Purpose: This study aimed to describe the periodontal condition of children, adolescents and young Saudi adults and to investigate its relationship with salivary variables and oral hygiene status. Materials and Methods: A sample of 114 children, 99 adolescents and 99 young adults were randomly selected from patients attending dental clinics at the school of dentistry. Clinical examination of oral health status included using WHO Community Periodontal Index and Green and Vermillion oral hygiene index. In addition, salivary flow rate, pH, buffering capacity and microbial flora were measured. Results: A healthy periodontal condition was found in 6.7% of the sample. Calculus was the most frequently encountered periodontal disease. Children had better periodontal condition than adolescents and adults. Males had higher plaque and gingival scores than females. The salivary flow rate and pH were significantly higher in individuals with good periodontal condition. The salivary level of fluoride and buffering capacity was not related to the periodontal condition. Yeast was the only microorganism related to periodontal condition. The relationship between poor periodontal condition and high plaque score was highly significant. Conclusions: Periodontal disease increased with age and was strongly related to salivary flow rate, pH value and yeast level, as well as plaque accumulation. Preventive efforts must be increased in order to achieve the WHO goal for the year 2010 of no more than one sextant showing bleeding or calculus at the age of 15.
Keywords: community periodontal index, microbial flora, oral hygiene, saliva

In a year not short of family drama, the Royals have been rocked by another scandal, this one concerning claims of historical racism.
It has emerged that until the 1960s, The Queen's courtiers banned "coloured immigrants or foreigners" from working in clerical roles within the royal household.
The explosive information comes after the perusal of papers found at the National Archives reports the MirrorOnline.
The same papers also show how Buckingham Palace insisted on clauses exempting the Queen and her household from laws that prevent race and sex discrimination.
In 1968, the Queen's chief financial manager informed civil servants that "it was not, in fact, the practice to appoint coloured immigrants or foreigners" to clerical roles in the royal household, although they were permitted to work as domestic servants, the Guardian newspaper said.
Buckingham Palace told the newspaper its records showed people from ethnic minority backgrounds being employed in the 1990s, but before that decade it did not keep records on the racial backgrounds of employees.
The newspaper highlighted how, in the 1960s, government ministers sought to introduce laws that would make it illegal to refuse to employ an individual on the grounds of their race or ethnicity.
The Queen has remained personally exempted from those equality laws for more than four decades, but it is argued the exemption made it impossible for women or people from ethnic minorities working for her household to complain to the courts if they believe they have been discriminated against.
A Palace spokesperson said on Wednesday: "Claims based on a second hand account of conversations from over 50 years ago should not be used to draw or infer conclusions about modern day events or operations.
"The principles of Crown Application and Crown Consent are long established and widely known
"The Royal Household and the Sovereign comply with the provisions of the Equality Act, in principle and in practise.
"This is reflected in the diversity, inclusion and dignity at work policies, procedures and practises within the Royal Household.
"Any complaints that might be raised under the Act follow a formal process that provides a means of hearing and remedying any complaint."

Research and implementation of intelligent decision based on a priori knowledge and DQN algorithms in wargame environment
MetadataShow full item record
AbstractThe reinforcement learning problem of complex action control in a multi-player wargame has been a hot research topic in recent years. In this paper, a game system based on turn-based confrontation is designed and implemented with state-of-the-art deep reinforcement learning models. Specifically, we first design a Q-learning algorithm to achieve intelligent decision-making, which is based on the DQN (Deep Q Network) to model complex game behaviors. Then, an a priori knowledge-based algorithm PK-DQN (Prior Knowledge-Deep Q Network) is introduced to improve the DQN algorithm, which accelerates the convergence speed and stability of the algorithm. The experiments demonstrate the correctness of the PK-DQN algorithm, it is validated, and its performance surpasses the conventional DQN algorithm. Furthermore, the PK-DQN algorithm shows effectiveness in defeating the high level of rule-based opponents, which provides promising results for the exploration of the field of smart chess and intelligent game deduction

Experienced Nashville Defense Firm
What Tennessee Drivers Should Know About the Implied Consent Law
Tennessee drivers can benefit from understanding their rights and the penalties that they may face under the state's implied consent laws.
Most people in Nashville are aware that they have the option of refusing chemical testing if they are suspected of driving under the influence. However, declining this testing is a violation of the Implied Consent law in Tennessee. When deciding whether to agree to chemical testing, drivers may misunderstand this law or the consequences of a violation. It's important for drivers to be familiar with implied consent so that they can better understand their options if they are accused of DUI.
Mandatory Associated Penalties for Violation of the Implied Consent Law
Like a drunk driving conviction, an implied consent violation can result in driver's license suspension. According to the Tennessee Department of Safety & Homeland Security, the mandatory suspension periods are as follows:
 - A first-time offense results in a one-year license suspension period.
 - A second-time offense is punishable with a license suspension period of two years.
 - A violation that occurs after a crash that causes injury is also sanctioned with two years of license suspension.
 - A violation that occurs after a fatal accident can result in five years of license suspension.
Drivers should note that refusing to take a chemical test is a civil rather than criminal offense. Therefore, drivers cannot be punished with jail time for implied consent violations. However, drivers may be charged with DUI in addition to these violations, and a DUI conviction may lead to incarceration.
Role in DUI cases
Many drivers decline to take chemical tests due to concerns that a test will provide evidence that supports a DUI charge. However, drivers should understand that refusal to take a test may also be used as evidence in a DUI case. Therefore, declining a field sobriety test does not guarantee that a driver will avoid a DUI conviction.
'No Refusal' laws
Many drivers who are familiar with Tennessee's implied consent law may be confused about their rights during "No Refusal" DUI campaigns. The TDSHS explains that during these campaigns, law enforcement authorities can more easily obtain warrants giving them the right to take blood samples from suspected drunk drivers. Such warrants override a driver's right to refuse blood testing.
WMC Action News notes that state law also allows forcible blood draws when a warrant is obtained and a driver still refuses to consent to testing. In the past, such forcible draws were only permitted in extreme cases, such as fatal accidents in which drivers were accused of vehicular homicide. Now, these blood draws are allowed whenever authorities have secured a warrant.
Seeking legal help
The confusion that many people have regarding implied consent laws helps show why legal advice can be beneficial. Immediately after a DUI arrest, an attorney may be able to help an accused driver understand his or her rights and options. An attorney also may be able to help a person challenge DUI charges and any related evidence, from field sobriety test results to chemical test refusal.
Frequently Asked Questions About Implied Consent
What is implied consent?
When a person applies for a driver's license in Tennessee, he or she gives "consent" to be tested for impairment. This "consent" is not made expressly by direct communication; rather, the consent is made implicitly. Stated another way, by applying for a driver's license, a person provides unspoken consent to be tested for impairment.
Is refusing to submit to a sobriety test your right by law?
Absolutely. You can refuse to submit to a breath test or blood draw. But if you do, your driver's license will be automatically suspended. That doesn't mean you won't be tested. As stated above, the police can obtain a warrant and forcibly draw blood.
What constitutes an equivocal or unequivocal refusal?
The word "equivocal" refers to a statement that has several meanings or an indeterminate meaning. In the context of blood alcohol testing, what types of responses could be considered equivocal? Hemming and hawing repeatedly when you are asked to submit to testing could be interpreted as an equivocal refusal. Likewise, making sport of the officer or joking about being tested could also be equivocal. On the other hand, explicitly saying "no" when asked to submit to testing is an "unequivocal" refusal.
What happens if I refuse a breathalyzer test?
Your driver's license will be automatically suspended for one year or longer. It may be possible to successfully appeal the suspension in a civil hearing, but positive results will depend on the specific circumstances of your case.
Is it better to refuse a breathalyzer test?
The answer depends on your specific situation. You have the right to consult with an attorney before consenting to a blood alcohol test, so you may want to take advantage of this right by speaking with a lawyer who is familiar with the implied consent laws of Tennessee.

Phase Change Heat Exchanger Project (Phase Change HX) - 03.29.17
Maintaining safe temperatures is difficult in space, where there is no atmosphere to provide warmth in the shade or protection from the sun's heat. Phase-change material heat exchangers can help by freezing or thawing a material to maintain critical temperatures inside a spacecraft, protecting crew members and equipment. Phase Change Heat Exchanger Project (Phase Change HX) tests a new type of heat exchanger that could help offset heat on future spacecraft, enabling future missions to better regulate temperatures. The test bed brings a new capability to the International Space Station (ISS) where test articles, requiring sub-zero fluid temperatures, can be tested on ISS. The Phase Change HX Payload includes a plug and play design allowing common interfaces for future payloads that require fluid temperature between -10°C to 30°C with flow rates between 50-300 lb/hr.

- Creating a unique test platform using the EXPRESS Rack on the ISS for testing phase change material heat exchangers (PCM HX).
- PCM HXs store energy by thawing a phase change material (i.e. wax or water) via hot coolant.
- The vehicle's radiators are capable of cooling the coolant, then refreezes the PCM for later use.
- Providing the ability to run numerous thaw/freeze cycles for the PCM HX while logging data from numerous temperature and pressure sensors.
- Sending the collected data to the ground team for processing and assessing how the PCM HX is performing in a micro-gravity environment.
- Removing the currently tested PCM HX within the experiment and installing a new PCM HX prototype with a different phase change material (i.e. water vs wax). This change-out will be capable of being performed by the on-orbit crew.
- Advancing the technology readiness level of phase change heat exchangers for use on future exploration missions.
- Assessing the performance of phase change heat exchangers in a micro-gravity environment.
- The ability to test numerous phase change heat exchangers capable of being installed by the on-orbit crew.
- Providing a low temperature loop (down to -10°C) that could be used in the future for other experiments in need of a lower temperatures than the ISS can currently provide.
- Entire experiment is contained within an EXPRESS Rack double locker.
- Utilizes the Moderate Temperature Loop (MTL), Low Temperature Loop (LTL), two EXPRESS Rack power connections, and one EXPRESS Rack data connection.
- Includes a contained Propylene Glycol Water (PGW) loop and a Thermal Electric Cooler (TEC) HX which provides the -10°C fluid used to freeze the PCM Heat Sink.
- The TEC HX includes strip heaters which provide the maximum 30°C fluid used to melt the PCM heat sink.
- Includes an avionics box which is cooled by the MTL and provides all data monitoring/logging and the software interface required to run the experiment from the ground workstation.
Wax-based phase-change heat exchangers have been used in space before, including on the Apollo lunar rover and the former Skylab space station, but with inconsistent results. A water-based phase-change heat exchanger has significantly better energy storage than wax, but it has not yet been tested in space. This investigation tests these heat exchangers in a microgravity environment, providing data needed to use phase-change heat exchangers on future space missions.
Phase-change heat exchangers are a low-energy means to control temperatures in chemical plants, power plants and other settings. By using materials that change phase from liquid to vapor depending on the temperature, facilities like power plants and factories can more easily move heat into areas that must be warmed by removing heat from areas that must be cooled. While this investigation is geared to space-based use, results improve basic research on phase-change heat exchangers.

Assault course
From Wikipedia, the free encyclopedia
Jump to: navigation, search
An assault course (also called trim trail) is a special sort of trail that combines running and exercising. It was more popular in the 1970s than it is now.[original research?] It is heavily used in military training. The prime use is to evaluate progress and weaknesses within the team involved.[original research?]
Military training[edit]
Assault courses are used in military training to increase fitness, to demonstrate techniques that can be used for crossing very rough terrain, and to increase teamwork and self-confidence.[original research?]
Often military assault courses will be standardised, and will have, for example (in the UK), a six foot and a ten foot wall, a climbing net, some type of bar to climb over, and a high rope or net that must be crossed (these being or representing the most likely difficult terrain that a soldier will come across). The standardisation means that every course will be to the same quality, though it also means that there will be certain parts that may be familiar if practised.[original research?]
However, they have different purposes. For example, they can be short (less than a minute) with a range on the end (e.g. Junior Leaders, Folkestone), or long (five minutes) as at Thetford.[original research?] This is partially because of space restraints and training objectives. The short one can be run as an individual course and a warmup for the range. The long Thetford course is more of an exercise in endurance and teamwork.
Trim trail[edit]
The term "trim trail" has more recently been applied to a series of wooden exercise stations, scattered in parkland or other locations beside a jogging or walking trail, which can be used to develop balance, strength and coordination.[original research?] They are suitable for both adults and children, and the individual stations have been scientifically designed to provide a range of exercise.[original research?] Most have simple instructions attached to them, and the stations include balance beams, sit-up bars, chin-up bars, parallel bars, and more challenging stations such as pole climbs and ladder walks.[original research?] Bristol City Council have now installed trim trails in six parks, ranging in complexity from Withywood Park, which has a single station, to Victoria Park, which has nine.[1][2] Funding for the trim trail at Hollingworth Lake, in Greater Manchester, which was the idea of the Friends of Hollingworth Lake and opened in August 2010, was provided by the Big Lottery Community Spaces fund.[3]

The house sparrow (Passer domesticus), popularly known as the "sparrow," is probably one of the most common birds in Europe. But what do sparrow eggs actually look like? Everything about color, size and general appearance can be found here.
To the point
- the typical appearance of sparrow eggs is a white to greenish ground with dark dots or spots
- each female lays eggs of an individual coloration and pattern, but this is the same for each egg
- the size of the eggs can vary greatly depending on the weather conditions
Shape and color
Sparrow eggs have an elongated-oval shape with the typical shape known from the hen's egg:
one pole very flat and almost round
one pole clearly pointed
Color can vary significantly from animal to animal, but remains largely constant per animal from egg to egg:
- basic color white to slightly greenish
- more rarely grayish basic coloration
- gray to brown mottling
- spots partly extremely dense up to the complete covering of the ground color
The average size of sparrow eggs is 15 x 22 millimeters with a weight of about 3 grams. However, this figure should be treated with some caution. Because observations show that the size of the eggs can vary greatly. Thus, even within one year with one and the same female, the volumes of the eggs can vary by up to 50% in each of the 2 to 3 clutches per season.
Science now believes it knows the reason for this: By adjusting egg size to the weather, sparrows provide their offspring with optimal conditions to start life. For while it is generally assumed that a larger egg offers better development opportunities, the state of knowledge is different in the case of the house sparrow. In cold and wet weather, a larger egg provides more nutrient reserves for better chick development. In warm dry weather, on the other hand, the excess supply leads to too rapid development, which causes stress to the organism during development and also later in life. Observations show that these animals have fewer offspring and lower life expectancies.
Note: This relationship may exist in other bird species as well, but has only been documented for the sparrow through observation and study.
A look into the sparrow's nest usually does not show only one sparrow egg. Instead, the typical appearance of the clutch is defined not only by the actual coloration, but also by the number of eggs it contains. Typically there are 4 to 6 eggs per clutch, although rarely 3 or even 7 eggs can be laid.
Frequently asked questions
Why are the sparrow's eggs speckled?
The sparrow lays its eggs in open nests that are fairly easy to see. The dots or spots serve to blur the outline of the egg and camouflage it as best as possible against the background of the nest.
Where does the slightly greenish coloration of the eggs come from?
Egg color is determined by two pigments that are present to a greater or lesser degree in all birds. One pigment has a blue base color, the other a red to brown base color. Depending on the intensity, ratio of both pigments to each other and layer of occurrence in the eggshell, the coloration can produce almost any color. In the sparrow, a low occurrence of the blue pigment mixed with minimal influences of the red pigment results in a slightly greenish coloration.
Where are sparrow eggs found?
The sparrow is known to be both a niche or cavity nester and an open nester. This means that its nest can be found in tree cavities and nest boxes, as well as in hedges, branch forks, and even on ledges on buildings, rocks, etc. This wide distribution of habitats used contributes significantly to its strong occurrence.


Using the ambassador pattern for reliable pipes-and-filters text processing
In our last article, Alex Anikiev, Arman Rahman and I introduced a text exploration pipeline based on microservices. The pipeline contains a variety of processing steps such as extracting plain text from a document, cleaning up and canonicalizing the text, extracting insights, and so forth.
Overview of the text exploration pipeline from the previous article.
In essence, the system described in the previous article implements a pipes-and-filters architecture orchestrated by HTTP calls: each microservice receives an input document via a request, performs a stateless document transformation and then sends its output to one or more independent downstream processing steps. This architecture has several advantages including speed of development and ease of maintenance: frameworks such as Express, Sanic or Spark enable us to quickly spin up web services and single-responsibility processing layers require less code to be understood or re-tested in the face of changes to any particular processing step.
However, the system has one big flaw: an orchestrator process has to manage the HTTP requests to the various services and pipe data between the inflight calls. This not only introduces a single point of failure but also makes it difficult to cleanly implement reliability features such as retries or handling intermittent failures. A natural way to improve system reliability is to introduce task queues between the processing steps, but this usually requires extensive code changes.
In this article we'll show how we improved the reliability of the pipes-and-filters architecture via task queues without any service-side code changes by leveraging the ambassador container pattern, thus unlocking the best of both worlds: an easy to develop text processing system that also is fault tolerant.
Definition
An ambassador container brokers interactions between the application container and the rest of the world. […] The two containers are tightly linked in a symbiotic pairing that is scheduled to a single machine.
Designing Distributed Systems also provides concrete usage examples for the ambassador container pattern such as service sharding: when the application container makes a request to an external service, the ambassador handles the logic required to dispatch the request to the correct shard of the sharded service. This allows the application container to remain simple since it's not burdened with the sharding logic.
Diagram demonstrating the use of the ambassador container pattern for service sharding
In the example above, the ambassador container hides the sharded nature of the dependent service from the application: the application does not need to be aware that it's talking to a sharded service such as for example a Redis cluster where data grew too large to fit into the memory of a single instance.
Following this example, we can use a variation of the ambassador container to improve reliability for our pipes-and-filters text processing architecture by transparently adding task queues to the system. Our text processing application container remains unchanged as a HTTP service and the ambassador container takes care of the integration with a queuing system:
 - Continuously, the ambassador container listens for messages on an input task queue.
 - When a message is received from the queue, the ambassador converts it into a web request to the text processing container and executes the request.
 - The ambassador container waits for the response from the text processing service and on receipt sends the appropriate messages to notify one or more downstream task queues of the result.
Diagram showing an ambassador container for injecting queues into the text processing pipeline
Note that the addition of the queues by construction improves the reliability of the system. For one, task queue implementations can be set up for high availability, thus removing the orchestrator as a single point of failure. Additionally, the task queues also protect against intermittent outages of the text processing containers: a message will only get deleted from the queue once the processing step is complete and all downstream messages have been enqueued; so if the processing of a message crashes part way through, it will simply be retried by the next available queue listener.
Implementation
We additionally decided to implement the ambassador container in C# since (unlike the Node SDK or Python SDK) the DotNet Core SDK for ServiceBus exposes a push-style API via AMQP. This simplifies the queue integration code by removing the need for implementing a message polling loop.
Setting up a simple tool that listens for ServiceBus messages, creates a post request and forwards the response to one or more downstream queues is fairly straight forward, as demonstrated by the snippet below:
The snippet above necessarily will have to contain some domain-specific logic to convert between a ServiceBus message and a HTTP request (omitted here for brevity), however, if the text processing steps all expose a unified interface such as "expect a posted plain text file and return a text response", the same ambassador container can be reused for all the processing microservices. Beyond the conversion logic, the code skeleton above is fully general and will enable any type of application to leverage transparent ServiceBus queues for improved reliability.
Deployment
Next, we can use the depends_on directive in Docker-Compose to connect the ambassador with its service on a single machine:
Alternatively, we can use multi-container pods in Kubernetes to orchestrate the ambassador next to its service in a cluster context:
Conclusion
The approach described in this article can be reused in any system where fault tolerance and automatic retries are important but where the application code should not be burdened with these concerns.

Do you need Image Classification in your IoT project? In this blog article, we will show you an easy way to develop a simple image classification application using Node-RED packages that are publicly available.
Who is this for? If you're new to low-code IoT programming and machine vision, this blog article will help you learn the ropes quickly and easily. If you've used Node-RED or are familiar with machine vision then you'll likely find our upcoming webinar more insightful as it tackles the challenges surrounding industrial machine vision IoT applications. Register here.
Toolkit: Node-RED, TensorFlow and Prescient Designer
We'll be using some open-source packages and libraries in this tutorial, so you can easily access them for this exercise.
Node-RED is an open-source software application that enables low-code programming of an IoT edge device. You'll be able to build this app quickly if you're already familiar with Node-RED. If you haven't used Node-RED before, it's still easy to get started with this introductory video.
Node-RED is focused on a single edge device, while Prescient Designer is built to scale
Node-RED and TensorFlow.js make it possible to design applications for remote monitoring, asset tracking or any other industrial application easily. However, Node-RED by itself only focuses on a single edge device, making it very difficult to scale your application to a large deployment.
However, Node-RED by itself only focuses on a single edge device, making it very difficult to scale your application to a large deployment.
Scaling Node-RED requires knowledge and experience in complex technologies and domain expertise like security, communication, protocols, orchestration and more.
That's where Prescient Designer can help. Prescient Designer is built for enterprise-class applications, with a specific focus on scaling large IoT deployments. It may look similar to Node-RED on the surface, but it's packed with advanced features like distributed programming, end-to-end security, recovery and rollback, remote collaboration built-in communication, application template solutions, and more. You can watch an overview of Prescient Designer's features here.
Getting Started with TensorFlow in Prescient Designer and Node-RED
This tutorial will work if you only have access to Node-RED, but it will be easier and more straight-forward with Prescient Designer. Watch our video tutorial to walk you through this exercise. Let's begin!
Installing Nodes from Palette Manager
Here are the required nodes you need to install from Palette Manager.
- node-red-contrib-browser-utils – This provides a file inject node to upload files from the browser
- node-red-contrib-image-output – Helps in viewing the image on the Node-RED editor.
- @prescient-devices/node-red-contrib-usb-camera - Enables image capturing from within Node-RED
- node-red-contrib-TensorFlow – Contains pre-trained TensorFlow models.
The node-red-contrib-TensorFlow node has 4 pre-trained tensorflow models.
- Object Detection -- The node to identify objects in an image
- MediaPipe Handpose -- The node to detect fingers in a hand
- MobileNet -- The node to classify images with MobileNet
- PoseNet Model -- The node to estimate human pose
It has been developed by Kazuhito Yokoi (@kazuhitoyokoi), software engineer at Hitachi and an avid node-red contributor.
If you're using Prescient Designer, import the template using Template Browser.
Things you'll need to successfully deploy this solution at the edge:
- Prescient Designer
- Any USB camera
- Raspberry pi 3+ or similar device.
If you're using Node-RED only, You can download the flow used in this tutorial here - image-classification.json.
Using MobileNet to classify images
In this demo, we will be using MobileNet to classify Images. If you want to see the full list of supported classes, you can access them here.
First, we'll drag in the required nodes inside the flow and wire them up.
Then, click on the "Deploy" button
Test your application by adding an arbitrary image using the file-inject node to see the results
There you have it! You just successfully built your first machine vision application using TensorFlow and Node-RED. Wasn't that hard, was it?
Applying your machine vision application to multiple edge devices
If you want to use the same image classification application on many devices, you will need to scale your application. Because Node-RED is a single system app, scaling this object classification solution to many devices will require expertise in vast domains from security to orchestration and everything in between.
Scaling your solution with Prescient Designer
We can use the power of Prescient Designer to deploy this solution to one edge device or thousands of edge devices with a single click of a button.
Instead of uploading images, we'll be using a camera connected to our edge device. It performs these actions:
- Take a picture
- Run inference
- Return back the result
Add (or provision) the edge device with Prescient Designer. Use ssh into the edge device and run the provisioning script found under settings. If you're not sure how to provision your edge device, you can visit our Documentation or simply follow this short tutorial video here.
Next, create a subflow. Add the following nodes to the subflow. The USB-camera node will get triggered on a message from input one and route the image to:
- Output 1 - Encoded Image for display
- Output 2 - The result of classification
Your overall flow should look like this:
Next, we'll convert this sub-flow to a device. The block of code inside the sub-flow will run on the edge device provisioned in the previous step.
Then, you can deploy and test your application.
You can download the flow used in this tutorial here, or watch this video tutorial demonstration. For more IoT learning, visit our Resource Library.
In our next blog article, I will show you how you can use TensorFlow models to classify custom images based on your application requirements.

Basics of Core HRMS in Oracle Apps Part6
Basics of Core HRMS in Oracle Apps
Application Programmatic Interface: API is nothing but a logical grouping of PL/SQL packaged procedures and functions, which acts as an interface to the database.
APIs are used extensively in Oracle HRMS. For every insert/update or delete to any of the base tables, an API is available.
APIs are primarily used to validate the data being inserted into the base tables and also for inserting or updating the data on deleting the data from the base tables.
Object Version Number
In Oracle HRMS, every row in the database table has an object version number. When a new row is created, the object version number for the row is 1. When the row is changed, the object version number is incremented by one. When a user queries a record, the object version number is also fetched along with the other information.
Consider, two users A and B query the same record having Object Version Number 1 simultaneously. If user A makes changes to the records and saves the changes, the current object version number (in this case 1) is compared with the object version number of the record in the database (in this case 1). Since, these values are same, the changes are valid and so the changes are saved and the object version number of the record is incremented by 1. It will become 2.
If user B also does changes and tries to save them, the object version number in the database is 2 against the object version number of the record sent to client (in this case 1). Since, the object version numbers are different, it is evident that the record is already changed by another user and so the changes done by user B are not valid as they may override changes done by user A.
The user B will get an error message:"Record has been modified by another user". He/she will have to re-query the record to do the changes.
This is one of the important parameters for an API.
Every API has a number of parameters. Not all parameters are mandatory. Generally, the optional parameters are followed by a default value, e.g. p_email_address in varchar2 default null.
Control Parameters
Control parameters are the mandatory parameters common across all the APIs.
This is one of the control parameters. For insert APIs, p_object_version_number is an OUT parameter. For update APIs, p_object_version_number is an IN OUT parameter.
This is an IN parameter. The parameter decides that the record needs to be saved to the database or not Default value for p_validate is FALSE. If TRUE value is passed, the data is only validated and not saved to the database.
APIs that are used to insert/update/delete the date tracked data have this control parameter. This is a mandatory IN parameter that defines the date from which the current change needs to be applied.
APIs used to update the date tracked data have this control parameter. Valid values for this parameter are: UPDATE, CORRECTION, UPDATE_OVERRIDE and UPDATE_CHANGE_INSERT
APIs used to delete date track data have this control parameter. Valid values for this parameter are: ZAP, DELETE, FUTURE_CHANGE, and DELETE_NEXT_CHANGE

Work Structures
SIT stands for Special Information Types.
This is nothing but the Personal Analysis Key Flexfield. This can be used to define any special information that cannot be stored with the help of the main system. Any number of instances can be defined of the Personal Analysis KFF. Each instance is knows as Special Information Type. Each SIT can have up to thirty fields. Each field is a segment of the KFF.
When a new segment combinations is created, the system will first check to see whether that combination already exists in the table before creating a row. If the combination does exist, the system only retrieves the ID of the row it found. The system therefore has to scan through the whole SIT combinations table.
SITs are primarily attached to people. They can also be used with Jobs, Positions, and Activities (in OTA), but with skill meaning (competencies).
EIT stands for Extra Information Types.
EITs are a type of Descriptive Flexfield. When a new segment combinations is created, the row is just inserted into the appropriate table (without checking whether the combination already exists). There is now full scan of the underlying table and so performance shouldn't be affected by the size of the table.
EIT's can be attached to People, Assignment, Job, Position, Location and Organization.

National Instruments has tested a subset of syntax possible in LabVIEW MathScript and found that this syntax typically executes in a bounded amount of time when used according to the examples and requirements in this topic and certain other guidelines. When determinism in your application is important, use this syntax to write scripts and user-defined functions for use in MathScript Nodes that you deploy in a real-time application.
General Operations
The following table provides recommended syntax for commonly used operations in MathScript.
Construct Grammar Requirements Example
Binary Operations a operator b operator is a numeric operator, such as +, -, .*, ./, .\, .^, <=, >=, <, >, ==, and ~=.
a and b are vectors of the same orientation and number of elements, or matrices of the same dimensions. Or, if one input is a scalar, the other input is a scalar, vector, or matrix.
a and b must be numeric data types only.
[1, 2] + [3, 4];
a operator b operator is a logical operator, such as ==, ~=, &&, ||, &, and |.
a and b are vectors of the same orientation and number of elements, or matrices of the same dimensions. Or, if one input is a scalar, the other input is a scalar, vector, or matrix.
a and b must be Boolean values only.
[2, 3; 2, 2] ~= [3, 3; 2, 3];
a * b a and b must be double-precision, floating-point numeric or complex double-precision, floating-point numeric values. One input is a scalar or vector and the other input is a scalar, vector, or matrix. 2 * [2; 3];
One input is an n-by-m matrix and the other input is an m-by-1 column vector. [1, 4; 2, 3; 0, 3] * [1; 2];
One input is a 1-by-n row vector and the other input is an n-by-m matrix. [1, 2] * [1, 3, 5; 2, 4, 6];
One input is an m-by-n matrix and the other input is an n-by-r matrix [0, 2; -1, 6; 3, 1; -2, 5] * [1, 3, 5; 2, 4, 6];
Unary Operations -a, ~a, a', a.' a is a scalar, vector, or matrix value.
For -a, a must be a numeric value or values. For ~a, a must be a Boolean value or values. For a' and a.', a must be either a Boolean or numeric value or values.
[1, 2]';
~[1, 0; 0, 1];
Constant Values constant constant is a MathScript function that produces constants, such as zeros, ones, true, false, and functions of the constants class. pi;
constant(n) n is a constant integer number and constant is a MathScript function that produces constants. a = true(3);
constant(n, m) n and m are constant integer numbers and constant is a MathScript function that produces constants. z = zeros(2, 3);
Literals literal literal is a string constant or a constant of any numeric data type. a = 4;
b = 'string';
Matrix Definition [a1, a2, ..., an] Values of a must be scalar values of any numeric data type, or constants such as NaN or Inf. If a is a vector or matrix, index scalar values from a for use in the matrix. a = [1, 2, 0];
b = [0; Inf];
Values of a must be scalar values of any numeric data type, or constants such as NaN or Inf. a = [1, 2, 0; 6, 1.5, 3];
Range Definition start:stop start and stop are constant scalar numbers of either integer or floating-point data types, or non-constant integer or floating-point numbers with the length of start:stop fixed over successive executions of the line of script. b = 2:20;
start:step:stop start, step, and stop are constant scalar numbers of either integer or floating-point data types, or non-constant integer or floating-point numbers with the length of (start:step:stop) fixed over successive executions of the line of script. b = 2:2:20;
Loops and Statements
The following table provides recommended syntax for loops and statements you can use in MathScript.
Construct Grammar Requirements Example
For Loop for iter = expression
statement_list
end
statement_list and expression, if applicable, are composed of operations, syntax, or built-in functions recommended by National Instruments in this topic and as described in other guidelines. expression must result in a scalar, vector, or matrix of numeric or Boolean values. for i = [3, 6, 9]
 a = sin(2*pi*i/10);
end
for iter = start:stop
statement_list
end
start and stop are scalar numbers of either integer or floating-point data types. for i = 1:10
 a = sin(2*pi*i/10);
end
for iter = start:step:stop
statement_list
end
start, step, and stop are scalar numbers of either integer or floating-point data types. for i = 1:2:10
 a = sin(2*pi*i/10);
end
If-Else Statement if expression
statement_list
[elseif expression
statement-list]
...
[else
statement_list]
end
expression must result in a scalar Boolean value. if b == 1
 c = 3;
else
 c = 4;
end
While Loop while expression
statement_list
end
expression must result in a scalar Boolean value. while i < 10
 a = cos(2*pi*i/10);
 i = i + 1;
end
Matrix Operations
The following table provides recommended syntax for indexing and replacing values in vectors and matrices, where values in italics indicate syntax for replacement operations only. Always specify indexes as 32-bit signed integers. When you specify a start:stop range, explicitly define the range rather than defining the range and assigning the value to a variable on a separate line of the script.
Vectors and matrices in MathScript are one-based, not zero-based as in LabVIEW. Therefore, the index of the first element in a vector or matrix is one. Also, when you specify a single index for a matrix element rather than both a row and column index, the elements are ordered linearly and column-wise. For example, given a 2-by-2 matrix, the index of the element in the first row and second column is 3.
Operation Grammar Example
Return or replace a single element in a vector vector(index) = scalar Return the second element of b:
b = [4, -7, 0];
b(2);
Return or replace a range of elements in a vector vector(start_index:stop_index) = vector Replace the second and third elements of b:
a = zeros(1, 2);
b = ones(1, 4);
b(2:3) = a;
Return a column vector of all elements in a row vector vector(:) a = ones(1, 4);
a(:);
Return a single element in a matrix matrix(index) Return the element in the second column and first row of b:
b = [4, -2; 9, 5];
b(3);
Return or replace a single element in a matrix matrix(column_index, row_index) = scalar Replace the element in the second column and second row of b:
a = 0;
b = ones(2);
b(2, 2) = a;
Return or replace a single column in a matrix matrix(:, column_index) = vector Return the second column of b:
b = ones(2);
b(:, 2);
Return or replace a single row in a matrix matrix(row_index, :) = vector Replace the second row of b:
a = zeros(1, 2);
b = ones(2);
b(2, :) = a;
Return a range of elements in a matrix matrix(start_index:stop_index) Return the third through fifth elements of b:
b = [3, 7, -1; 4, 5, 0];
b(3:5);
Return a range of elements in a matrix column matrix(start_index:stop_index, column_index) Return the second through fourth elements of the second column in b:
b = [3, 7; -1, 4; 4, 5; 0, 9];
a = b(2:4, 2);
Return a range of elements in a matrix row matrix(row_index, start_index:stop_index) Return the second through fourth elements of the second row

We use Postgres 9.3, we want to split a large database (evaluated final size will be > 100 T) on many servers. As our users already have a set of existing queries, we cannot use solutions like PL/Proxy. We would like to use the postgres_fdw contrib to externalize some part of the data.
To illustrate our problem, we created 2 foreign tables foreign_table_1 and foreign_table_2. As inheritance seems not available on foreign tables, we created an union view like this :
CREATE VIEW union_table (id, name) AS ( SELECT id, name FROM foreign_table_1 where id BETWEEN 1 AND 100000 UNION ALL SELECT id, name FROM foreign_table_2 where id > 100000 ) ;
The problem is that Postgres does not push the constraints into the query plan. For instance here both foreign tables are scanned :
postgres=# explain analyze select * from union_table where id = 1234; Append (cost=100.00..303.35 rows=5 width=8) (actual time=1.113..1.113 rows=0 loops=1) -> Foreign Scan on master_table_1 (cost=100.00..154.82 rows=1 width=8) (actual time=0.567..0.567 rows=0 loops=1) -> Foreign Scan on master_table_2 (cost=100.00..148.48 rows=4 width=8) (actual time=0.538..0.538 rows=0 loops=1) Total runtime: 1.876 ms (4 rows)
- Is it possible to push the WHERE clause into the query plan?
- Is it possible to use inheritance with postgres_fdw?
- Is there any other way to obtain a sharded table with Postgres?

Multiple-Valued Logic Design in Current-Mode CMOS
Over the last two decades, design using Multiple-Valued Logic (MVL) has been receiving considerable attention. With recent advancements in processing technologies it is now possible to implement higher-radix functions. MVL circuits have shown the potential of improving the use of chip area through increased functional density and reduced requirements for interconnection wiring. Currently, it is advantageous if MVL circuits are used along with binary circuits in the design of Very Large Scale Integration (VLSI) circuits. In order to minimize the fabrication process related overheads, it is desirable to design MVL circuits that can coexist on the same chip with binary logic circuits. This thesis considers MVL design in current-mode CMOS compatible with existing binary logic CMOS fabrication processes. A given MVL function can be realized in the sum-of-product (SOP) form. The realization cost, in terms of the number of required product terms (PTs) and hence the circuit area, depends on the set of operators used. The choice of the set of operators is technology dependent. A new set of operators, consisting of literal, cycle, complement of literal, complement of cycle, min, and tsum operators is proposed in this thesis. A general structure has been identified for realizing MVL circuits in currentmode CMOS. The structure consists of input, control, and output blocks. The input and the output blocks deal primarily with multiple-valued current signals. The control block signals are binary voltage signals providing flexibility by allowing the use of arbitrarily complex binary circuits. MVL circuits have been designed for the new set of operators using the general structure. The cost, in terms of number of transistors, of realizing the new set of operators and that of each of the existing sets of operators is comparable. The functionality of the designed circuits has been verified for 4-valued logic using HSPICE transient analysis simulations. MVL function realizations using the new set of operators requires fewer PTs compared to realizations based on the existing sets of operators. A comprehensive comparison has been conducted for all 19683 3-valued 2-variable functions. The maximum number of PTs is reduced from 6, using the existing set of operators, to 3, using the new set of operators. The average number of PTs is decreased from 3.61 to 2.61. Sample 4-valued 2-variable function realizations using the new set of operators have also shown similar improvements. In the past, several heuristic-based programs have been reported to obtain an efficient SOP expression for a given MVL function. HAMLET is one of these programs. It accepts user specified function expression and minimizes this expression. It includes implementation of many earlier reported heuristic-based algorithms. The Gold heuristic chooses the best realization after applying all other heuristics implemented in HAMLET. A new heuristic-based synthesis program has been developed to obtain a SOP expression for a given MVL function using the proposed set of operators. For a random sample of 4-valued 2-variable functions, the realizations have been compared for the developed program and the existing program, HAMLET (Gold). It is observed that for 69% of the functions, the developed program performs better and for 4% of the functions the HAMLET (Gold) realizations are better. The average number of PTs required by the developed program and HAMLET (Gold) are 5.53 and 6.62, respectively. In order to further reduce the number of PTs required for MVL function realizations two new approaches have also been identified. The new approaches are based on difference-of-sum-of-products (DOSOP) and sum-of-terms (SOT) realization of MVL functions. It has been shown that the required number of terms can be reduced in the realization of some MVL functions, using the new approaches, as compared to those obtained using the SOP realization.

[FFmpeg-devel] Definition of audio and video frames according to av_read_frame()
Unga unga888 at yahoo.com
Sun Aug 26 08:52:22 CEST 2012
Dear all
FFmpeg documentation says "For video, the packet contains exactly one frame. For audio, it contains an integer number of frames if each frame has a known fixed size (e.g. PCM or ADPCM data). If the audio frames have a variable size (e.g. MPEG audio), then it contains one frame."
1. Regarding video, does av_read_frame() return anything other than I-frame,
P-frame or B-frame?
2. Regarding audio, what is the definition of audio frame? If I say, an audio frame contain one audio sample, is it correct?
Many thanks in advance.
Best regards

I am working on a code that searches a folder gets a specific part of the file name and adds 1 to a file counter. There are some files in tehre that have a special character that indicates that is is only half. I ahve got it to count the full ones but can not figure out a way to get the half ones to count. The special character that is in the names to inficate half is H. If someone could please help me figure this out it would help increase my production time.
def bedCount(pathname, bednumber):
 filecount = 0
 for file in os.listdir(pathname):
 if fnmatch.fnmatch (file, ''+bednumber+''):
 filecount = filecount+1
 return filecount
countbeds=bedCount(filestart, 'B')
print countbeds
I'am using different imports and python 3
import tkinter.filedialog as tk_FileDialog
from tkinter import*
fileCount = 0
for x in range(0,10) #read as many as you want
 f = tk_FileDialog.askopenfile(mode='r') #Or what file your trying to open
 fileContents = f.readlines(1) #Or what lines you want to read
 if fileContents == 'H':
 fileCount += 0.5
 elif fileContents == 'h':
 fileCount += 0.5
 else:
 fileCount += 1
print "File count was", fileCount
This is if the first letter of the filename is the indicator otherwise regex required.
import os
def fileCheck(pathname):
 countB = 0
 countH = 0
 for file in os.listdir(pathname):
 if file[0] == 'B':
 countB += 1
 elif file[0] == 'H':
 countH += 1
 else:
 pass
 return countB, countH
Maybe more explicit and hence more pythonic? Unsure.
import os
def fileCheck(pathname):
 countB = 0
 countH = 0
 for file in os.listdir(pathname):
 if file.startswith('B'):
 countB += 1
 elif file.startswith('H'):
 countH += 1
 else:
 pass
 return countB, countH

Little Rock, Arkansas
The Federal Reserve Bank in Little Rock stood vacant for many years, until a $5.9 million rehabilitation transformed the building into a charter school. The building retains many of the unique bank features, including the vault and lobby gun tower originally used to protect the currency, from its construction in 1924. The recent renovation, assisted by a Federal Historic Preservation Tax Credit, allowed the exterior of the building to remain largely the same while the interior was adapted for educational needs. The lobby was restored and glazed walls were added to allow spaces to be used for classrooms. The rehabilitation revealed original historic features including fluted columns and plaster ceilings that were obscured in the past.

Schooner – a sailing vessel with fore and aft sails on three masts. The foremast being shorter than the mainmast which is no taller than the mizzen mast.
What ship is bigger than a galleon?
I'm sorry, but that is not a quantifiable statistic. A ship size bigger than a galleon would quite frankly be a frigate rather than a man o war/ship of the line. Frigates are actual predators as far as ships go, designed to seek and destroy/capture enemy ships and raid merchants.
Why is the black pearl so special?
In the movie Pirates of the Caribbean: The Curse of the Black Pearl, the Black Pearl was able to easily beat the speed and firepower of the HMS Interceptor, which was the fastest warship in the British Royal Navy fleet and specially designed to crush pirates.
Why was the Black Pearl cursed?
Barbossa, who was Jack's first mate aboard the Black Pearl, led a mutiny against Jack and marooned him on a desert island. Sometime after finding the treasure, the crew suffered under the Aztec curse; a curse they originally thought to be a ridiculous superstition and didn't believe to be true.
Where did they poop on old ships?
It is a nautical or naval term that goes back to the day of the old sailing ships. Let's start at the back of the ship. The upper-most rear, or the stern, was called the poop deck.
What is the poop on a ship?
In naval architecture, a poop deck is a deck that forms the roof of a cabin built in the rear, or "aft", part of the superstructure of a ship. The name originates from the French word for stern, la poupe, from Latin puppis.
What was the biggest wooden warship ever built?
The longest wooden ship ever built, the six-masted New England gaff schooner Wyoming, had a "total length" of 137 metres (449 ft) (measured from tip of jib boom (30 metres) to tip of spanker boom (27 metres) and a "length on deck" of 107 m (351 ft).
What are big ships called?
Tanker Ships Tanker ships are specialised vessels for carrying a large amount of liquid cargo. Tankers are further sub-divided into different types on the basis of the cargo they carry.
How rare is a black pearl?
Black pearls are formed when that piece of sand gets stuck in the body of a very specific type of oyster, the Tahitian black-lipped Pinctada margaritifera. … This, however, is rare; it occurs in only one in 10,000 pearls.
What was the first ship to sink?
The first cruise ship ever built to ply the frigid waters off Antarctica became the first ever to sink there. The red-hulled M/S Explorer struck ice Friday, took on water as 154 passengers and crew members scrambled to safety aboard lifeboats and rafts, and then it went to the bottom.
What does Galleon mean?
: a heavy square-rigged sailing ship of the 15th to early 18th centuries used for war or commerce especially by the Spanish.
What is a boat with 3 masts called?
A barque—a three-masted sailing ship with square sails on the first two masts (fore and main) and fore-and-aft sails on the mizzenmast.
What is a boat with 2 masts called?
A ketch is a two-masted sailboat whose mainmast is taller than the mizzen mast (or aft-mast), generally in a 40-foot or bigger boat. The name ketch is derived from catch. The ketch's main mast is usually stepped in the same position as in a sloop.
What are pirate ships called?
Sloops. Sloops were the most common choice during Golden Age of Pirates during the 16th and 17th century for sailing around the Caribbean and crossing the Atlantic. These were commonly built in Caribbean and were easily adapted for pirate antics.
How did pirates poop on ships?
What is the biggest ship in the world?
Seawise GiantThe largest ship in the world by length is the oil tanker Seawise Giant at 1,504 feet (458.46 meters). It was in service from 1979 to 2009. In the decade since its retirement, no ship has surpassed its length.
What is the oldest ship in the world?
Pesse canoeThe Pesse canoe is the world's oldest known ship, dating between 8040 and 7510 BC.
What are the small boats on a pirate ship called?
yawl (or dandy) A ships small boat crewed by rowers. A two-masted fore-and-aft-rigged sailing vessel similar to the ketch but having a smaller jigger or mizzenmast projecting out behind the rudder.

How to Enable Automatic Callback
In this article
Introduction
At the end of this article, you will be able to configure the PBX queue callback object within your call flow. The article will also assist you with some common uses for the object within your PBX configuration. Should you need any assistance, feel free to contact our support department.

Configuring a PBX queue callback
The PBX queue callback object allows a caller being held in a queue the ability to request a callback when they reach position 1. When the caller reaches this position, all available agents assigned to the queue callback will ring according to the ring mode configuration. Once you have logged into your customer portal, click on the PBX tab. Then select the queue callback from the toolbox menu on the left, drag and drop the object onto the main configuration screen. Next, click on the settings icon.

callback1.PNG

You should now enter a descriptive name and add the agents by clicking on the add green button. Enable user control is a feature which allows the user to accept or decline the callback request. This is not recommended for call centre environments. If this option is disabled, the agents would not have the option to reject the callback.
mceclip0.png
On top of this, it is possible to configure your desired callback hours, the interval between callbacks (pause between callbacks), and the delay to send a new callback request to a user that has just finished a callback, this is known as the wrap-up time.
mceclip1.png
Lastly, it is important to set your desired caller ID, this is the number that your callback requesters will see on their phone, and there is the ability to email notification if the callback times out, or does not connect. Don't forget to save and apply the new configuration.

mceclip2.png

PBX queue callback usages

This scenario simulates a medical clinic that has two receptionists coping with all customer's appointments. During peak business hours the receptionists are unable to handle the increased volume of inbound calls and eventually they reach the queue timeout clause, or the callers abandon the call. With this in mind and to provide a better customer experience, the medic clinic manager decided to utilise a queue callback object when the calls time out.

callback3.PNG

The callback object was configured in a way to allow the receptionists the ability to accept or reject the callback requests, an extended length for the callback duration to allow for the backlog of the peak business hours to settle and finally, an email notification to catch all failed callback requests for the medical centre manager to review.

mceclip3.png
Calls now have the ability to request a callback once they time out in the call queue. However, if the abandon ratio was very high on the call queue, it would be recommended to enable the exit clause on the call queue and point to a callback object, this would allow the callers the ability to press a number to leave a callback request.

_URL_ TableViews, collectionViews and Swift enums 2016-03-15T12:37 2016-03-15T12:37 Roland Leth _URL_ I talked about how we can have a safer and cleaner tableView/collectionView section handling, but we can improve it even further, with protocol extensions:
protocol Countable {
 var rawValue: Int { get } // 1
 init?(rawValue: Int) // 2
 static var count: Int { get } // 3
}
This is a protocol that mimics an enum that conforms to Int: it has a rawValue of type Int (1), it has an initializer based on said rawValue (2), and it has a static var (3) that will be used to hold the total number of cases. And here's where extensions come into play:
extension Countable {
 static var count: Int {
 var max = 0 // 1
 while let _ = self.init(rawValue: max) { max += 1 } // 2
 return max // 3
 }
}
We start from 0 (1), and, as long we can create a case from the current max, we keep incrementing max by 1 (2). When a case can no longer be created, it means we previously reached the last valid case, so we will return max (3) -- one valid case means 0 + 1 = 1, two mean 0 + 1 + 1 = 2, and so on.
Then, when we create an Int enum, we just have to also conform to Countable, and we'll have the number of cases out of the box:
private enum Section: Int, Countable {
 case products
 case shippingDetails
 case paymentDetails
 case totalValue
 // numberOfSections - we don't need this anymore
}
print(Section.count) // 4
As I mentioned in the previous post, this approach only works for UITableViews and UICollectionViews, but does so perfectly.

_URL_ Frame debugging on a device 2016-03-11T16:58 2016-03-11T16:58 Roland Leth _URL_ There's this handy feature, Debug -> View Debugging -> Show View Frames, which, if turned on, draws borders around views. The sad part is that it only works on the simulator. But we can (somewhat) easily simulate its behavior.
First, we create a helper method that does the coloring:
func activateFramesDebug() {
 guard debugFrames else { return }
 layer.borderWidth = 1
 layer.borderColor = UIColor(
 hue: CGFloat(arc4random_uniform(100_000)) / 100_000,
 saturation: CGFloat(arc4random_uniform(100_000)) / 100_000,
 brightness: 0.5 + CGFloat(arc4random_uniform(50)) / 100,
 alpha: 1.0).CGColor
}
Then, we override drawRect / layoutSubviews, depending on the extension:
// Easy to avoid production slips, easy way to turn on / off.
#if DEBUG && false
let debugFrames = true
extension UILabel { // UIImageView, etc...
 override public func layoutSubviews() {
 super.layoutSubviews()
 activateFramesDebug()

}
extension UIButton { // UITableViewCell, UICollectionViewCell, etc...
 override public func draw(_ rect: CGRect) {
 super.draw(rect)
 activateFramesDebug()
 }

}
#else
let debugFrames = false
#endif
It will not always work perfectly, it's not a perfect solution, but it's better than nothing. I'm also hoping there's an easier / better way to do this, but I don't know where we could hook up in an UIView extension. Let me know @rolandleth if you find a better solution.

_URL_ Improving git log 2016-03-03T11:17 2016-03-03T11:17 Roland Leth _URL_ We can already use --graph and --decorate to get a pretty, colored commit tree, but we can create a function for less typing, more flexibility and more info:
git_branch() {
 git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/'
}
# Short for git decorated log
gdl() {
 branches=''
 if [ -n "$1" ] && [ -n "$2" ]; then

 elif [ -n "$1" ]; then

 git log --oneline --graph --decorate $branches
 echo "${blue}Difference: ${green}$(git rev-list --count $branches) commits."
}
This will also print the number of commits between the two branches at the end, and the rules are as follows:
 1. If we pass in two parameters, it will show the differences between the two branches.
 2. If we pass in just one parameter it will either
 - print the current's branch tree, if the parameter is equal to the keyword (make sure it's something unique), or
 - show the differences between the current branch and the one passed in.
 1. If no parameter is passed in, it will show the differences between a fallback branch (in this case master) and the current branch.

_URL_ Working easier with tags 2016-02-27T15:02 2016-02-27T15:02 Roland Leth _URL_ One usual approach is to create an enum, so your tags are more expressive by having a name:
enum ViewTag: Int {
 case none
 case titleLabel
 case loginButton
}
Then tagging and retrieving views by tag will be safer, and easier to remember:
let container = UIView()
let titleLabel = UILabel()
container.addSubview(titleLabel)
titleLabel.tag = ViewTag.titleLabel.rawValue
let loginButton = UIButton(type: .Custom)
container.addSubview(loginButton)
loginButton.tag = ViewTag.loginButton.rawValue
if
 let titleLabel = container.viewWithTag(ViewTag.titleLabel.rawValue) as? UILabel,
 let loginButton = container.viewWithTag(ViewTag.loginButton.rawValue) as? UIButton {
 // Do stuff.
}
This is already much better than triple checking that the titleLabel's tag really is 1 and not 2, but what if we can go a step further and improve this, by extending UIView?
extension UIView {
 func tag(with value: ViewTag) {
 tag = value.rawValue
 }
 func viewWithTag(_ tag: ViewTag) -> UIView? {
 return viewWithTag(tag.rawValue)
 }
 // Speaking of Swifty, we could also change the above in:
 func view(tagged tag: ViewTag) -> UIView? {
 return viewWithTag(tag.rawValue)
 }
}
So all of our code can be shorter, cleaner and prettier:
let titleLabel = UILabel()
view.addSubview(titleLabel)
titleLabel.tag(with: .titleLabel)
let loginButton = UIButton(type: .Custom)
view.addSubview(loginButton)
loginButton.tag(with: .loginLabel)
[...] // somewhere else
if
 let titleLabel = view.viewWithTag(.titleLabel) as? UILabel,
 let loginButton = view.view(tagged: .loginButton) as? UIButton {
 // Do stuff.
}

Recently, the Grand Canyon National Park officials have been reminding visitors that the use of rodent poison is illegal after the discovery of a deceased bobcat in the park.
On Tuesday, the National Park Service reported that a bobcat found in Grand Canyon Village on the South Rim had passed away due to an excessive amount of rodenticide in its system.
In recent years, a variety of animals such as condors, coyotes, foxes, mule deer, and chipmunks have been killed by rodent poison, even if they did not ingest the lethal chemicals.
At Grand Canyon National Park, why is the use of rodenticides prohibited?
Park officials have indicated that the use of poison to eradicate rodents may have unintended negative repercussions. It could lead to contamination of the ecosystem and put other species that feed on the poisoned rodents at risk. Harm to both humans, especially kids, and animals is a possible consequence.
At the Grand Canyon, the use of rodent poison is only allowed in certain, specified circumstances when it is necessary to stop the spread of disease.

Located in Central Highlands geography zone, Dalat has the geographic coordinates from 11°48'36'' to 12°01'07'' north latitude and 108°36'27'' east longitude. Dalat shares borders with Lac Duong district in the north, Don Duong District in the east and southeast, Lam Ha District in the west and Duc Trong District in the southwest.
Dalat topography has the average height of 1,500 m above the sea level. The highest place in the city is Nha Bao Tang (1,532m) while the lowest one is Nguyen Tri Phuong valley (1,398.2m). Dalat terrain is classified into two distinct types including lowlands and mountainous areas. The lowlands have a shape of a basin having hills with round peaks and steep slopes. The average height of this region is about 1,500m.The mountainous areas are distributed surrounding the highlands. Mountains have the height of 1,700 meters forming a windbreak belt for the lowlands. In the direction of the north, Lang Biang range of mountains looks like a wall towards the northeast - southwest stretching from Da Sar stream to Dankia lake. The two highest peaks of the range has the height of 2,167 m and 2,064 m. Bi Doup and Cho Proline ranges of mountain are locate in the east and southeast of Dalat.
Because of lying in the altitude of 1,500 m and covering by ranges of mountain and forests, especially pine forests, Dalat climate is pretty mild and temperate all year round. Located in the tropical savanna climate, Dalat has two distinct seasons including rainy seasons and dry seasons. Rainy seasons last from May to October often witnessing the presence of the southwest monsoon winds. On the other hand, dry seasons are influenced by the northeast monsoon winds lasting from November to April. In dry seasons, Dalat is affected by the air mass of the South China Sea which brings the sunny weather. The weather in this season has less clouds and no rains with the lower temperature at night and the large temperature range. In rainy months, the northeast monsoon winds almost have no influence on Dalat anymore. It is replaced by the equatorial air mass moving from the south to the north. The southwest monsoon winds bring the major source of humidity causing heavy rains. However, due to the influence of the tropical air mass of Pacific, there are still some dry periods in rainy seasons.
Temperature: The average temperature in Dalat never exceeds 20°C even in the hottest months. In winter, the average temperature of Dalat is over 14°C. Diurnal temperature range in Dalat is very large with the average number of 11°C.
Sunshine hours: The total sunshine hours in the city are relative high, about 2,258 hours per year focused mainly from December to March in dry seasons. The total amount of radiation in Dalat is approximately 140 kCalo/cm2/year. In comparison to other regions, the amount of solar radiation in Dalat is not high; however, it brings the relatively low and mild temperature for the city.
Rainfall: On average, Dalat City has 161 rainy days with the total rainfall is 1,739 mm mostly focused on July, September and October. The rainfall from May to October accounts for 80% the total amount of one year.
Fog: The average number of days having fog is 80 - 85 days per year. However, this phenomenon appears mostly from February to May and from September to October.
Alternating between low hills and surrounding mountains, Dalat has over 20 streams belonging to a system of Cam Ly and Da Tam streams, and Da Nhim River system. These streams are the headwaters belonging to the basin of Dong Nai River. A half of these streams are shallow and only flow in rainy seasons. Cam Ly stream has 64.1 km in length derived from Lac Duong district flowing in the direction of north - south. This is the largest stream of Dalat having an important role in the creation of urban landscapes.
In addition, Dalat is known as the city of lakes and waterfalls with about 16 big and small lakes which are widely distributed. Xuan Huong Lake is located in the centre of the city. The total area of Xuan Huong Lake is 38 hectares created in 1919 during the construction of Dalat. Before 1986, Xuan Huong Lake and Than Tho Lake are the main sources providing water for the city. Nowadays, the water for daily activities of local people is taken from Dankia Lake (Lac Duong District).

In December, the Guardian UK website posted the questions for the notoriously difficult King William's College quiz or General Knowledge Paper (GKP) given to students (and parents) at King William's College on the Isle of Man. In another article on, "The Story of the King Wiliams's College Quiz" quizmaster Dr Pat Cullen discusses the impact of the Internet on the 106 year old quiz and attempts to Google and social media proof the quiz to keep it intellectually challenging. MacLean's Canada article on the history of the quiz is simply titled, "The World's Most Difficult Quiz. Really."
While only section 2 relates specifically to geography and cartography, I estimated that about 70 of the 180 questions could be considered geo-spatial. These range from questions such as, "4 Who first used continuous and broken lines to indicate fenced and unfenced roads?" to 5 Where did close neighbours claim the invention of a device for observing at a distance? The answers to last year's questions were posted in February, so you will have to wait a while if you get stumped.
The quizmaster Dr. Pat Cullen doesn't live in a dusty library tower, he is also a birder and citizen scientist for the Isle of Man which is home to several rare species of birds.

SPEXOR: Design and development of passive spinal exoskeletal robot for low back pain prevention and vocational reintegration
A Correction to this article was published on 15 April 2019
This article has been updated
Abstract
The objective of SPEXOR project is to address low back pain as one of the most appealing health problems of the modern society by creating a body of scientific and technological knowledge in the multidisciplinary areas of biomechanics, robotics, and computer science that will lead to technologies for low back pain prevention. In this paper we provide an overview of the current state-of-art of SPEXOR that the consortium achieved in the first twenty-four months of the project. After introducing the rationale, we describe the biomechanics of low back pain intervention, development of the musculoskeletal stress monitoring for assessment of neuromuscular trunk functions, modeling and optimization of the interaction of spinal exoskeleton with the human body, electromechanical design and development of the passive spinal exoskeleton and its control, and finally the end-user evaluation of the functional effects, usability and satisfaction.
Introduction
Low-back pain (LBP) is often termed a pandemic of the modern world and represents great socioeconomic burden. Epidemiological studies have shown correlation between physically demanding jobs and prevalence of LBP, symptoms exaggeration and back injuries. Among these jobs handling heavy loads, repeated lifting and working time spent in flexed position are the most challenging. The objective of SPEXOR project is to address LBP by creating a body of scientific and technological knowledge in the multidisciplinary areas of biomechanics, robotics, and computer science that will lead to technologies for LBP prevention. In the following sections we provide an overview of the current state-of-art of SPEXOR that the consortium achieved in the first twenty-four months of the project.
Biomechanics of LBP intervention
Based on literature with regard to risk factors of LBP we established core requirements for each of the SPEXOR systems. These requirements included key variables to control, and their safety limits. Furthermore, using existing benchmark passive and actuated exoskeletons, we assessed how such systems interact with subject behavior in static trunk bending, dynamic lifting, and functional activities [1]. We found that current systems do reduce spine loading, especially during static work (Fig. 1). However, load reduction during dynamic lifting is insufficient, i.e. below 10%, and functional activities are hindered to some extent [2]. Additionally, current systems cannot be tuned to individual properties such as spine flexibility. These findings resulted in specific biomechanical requirements for the spexor passive and actuated systems. Iterative prototype testing is being performed in order to optimize the SPEXOR systems. Furthermore, based on parallel measurements of lab and mobile systems, we defined the optimum set of sensors, needed for real time monitoring of low back loading at the workplace [3, 4]. We subsequently tested the resulting SPEXOR sensor set under controlled conditions, and we found that it is capable of monitoring low back load with sufficient accuracy. At present, we are testing how real time feedback of such a system affects subject behavior and spine loading.

Musculoskeletal stress monitoring
One important aspect that is being researched in the project SPEXOR is a musculoskeletal stress monitoring system. With this monitoring system, it is possible to estimate biomechanical parameters such as joint angles and moments, especially from lumbar joints. This information it is used to send a feedback signal in critical situations. For example, when the person has surpassed an ergonomic limit during a working day. The monitoring system is based on inertial measurement units (IMU) place at different parts the human body, as well as force insole technology. These sensors are connected wirelessly to a base station. The system was designed to be robust, easy to wear and comfortable. The logistics industry is a good example of a use case scenario for this monitoring system. Lifting boxes is a typical scenarios in this industry (Fig. 2). Therefore, a biomechanical model was developed to identify the kinematics and dynamics of the movements done to lift a box [4,5,6]. This model is based on a rigid multibody system that solves the inverse kinematics and outputs the position and velocities of all degrees of freedom. The force insoles are used to provide the necessary information to solve the inverse dynamics, which gives the information of internal joint moments, i.e. to estimate the L5/S1 joint moments. For the system to work in a real scenario, the model has to be optimized for real-time operation taking into account the limitations of the wireless transmission from the sensors, of drifting of the IMU signals, and of the computer processing power. For the future, it is important to develop a parametrized model that can be customized to the height and weight of the user. This way it is possible to derive the length, mass, center of mass and inertia tensors of the segments using the regression method [7].

Modeling and optimization
In SPEXOR, model-based optimization is used as a tool to analyze and predict motions that are critical for the lower back and to design exoskeletons that best support such motions. For this purpose, we have developed subject specific multi-body system models describing various lifting and bending motions that take dynamic properties as well as characteristics of muscular joint torque generation into account. For describing the exoskeletons, a sequence of models with different components and free parameters has been established in the course of the project, to evaluate different design concepts for passive and active exoskeletons, involving rigid segments and bendable parts as well as compliant elements, damping and actuators in the joints. We have investigated two types of optimal control problems:
 1. 1.
 Optimal control for motion analysis: focusing on a tracking of recorded motions of healthy subjects without exoskeleton with combined human-exoskeleton models to explore how exoskeletons can provide maximum support for such standard motion patterns.
 2. 2.
 Optimal control for motion prediction: applying different objective functions such as a minimization of activation or a minimization of joint torques to predict motion trajectories for these behavior rules as well as parameters and (in the active case) required motor torques of the exoskeleton.
In these models, the connection between human and exoskeleton model can be described by either constraint forces or compliant forces which both allow to analyze these interaction forces and limit them to stay below ergonomically acceptable constraints. Figure 3 shows two example models investigated. More details can be found e.g. in [5, 8] or [9]. Current research on modeling and optimization in the SPEXOR project involves inverse optimal control of patients with back pain, with the aim to identify behavior models in terms of optimality criteria for such patients with which further motion prediction and design optimization can be performed.

Examples for models of a passive (a) and an active (b) exoskeleton model investigated in SPEXOR
Electromechanics of spinal exoskeleton
Based on the musculoskeletal stress monitoring system as well as the robot-centred requirements for LBP intervention, we developed a passive spinal exoskeleton that achieves a similar range of motion as a human lumbar spine of up to \(60^\circ\) in the sagittal plane. We addressed this need by developing and testing a novel passive back support mechanism that consists of an elastic back support mechanism, the misalignment compensating hip module and a passive hip torque source. The elastic back support mechanism is comprised of flexible beams that run in parallel to the spine, providing a large range of motion and lowering the peak torque requirements around the lumbo–sacral (L5/S1) joint. The misalignment compensating hip module is a mechanism with three parallel hinge joints that compensate the misalignment and provides a good fit of the exoskeleton to the human body. Two torsional springs are mounted on the top two joints to avoid singularities and increase comfort. The passive hip torque source is a purely passive version of the Mechanically Adjustable Compliance and Controllable Equilibrium Position Actuator (MACCEPA 2.0) (Fig. 4).

This paper looks at why work-related road safety is important in Australia, and introduces the Haddon Matrix as a tool to identify and manage the distractions faced by people driving as part of their work. It is intended as a discussion paper to provoke and widen the debate on driver distraction beyond the vehicle and the driver.
What causes driver distraction and tools to help reduce the risk?
Fleet and work-related road safety has grown in prominence in recent years as the scale of the problem has emerged. This includes people involved in crashes as pedestrians when they are commuting to and from work, or walking on work-related errands, people involved in crashes whilst working by the roadside, or driving as part of their work, either in their own vehicle or a vehicle provided by their employer (STAYSAFE 36, 1997; STAYSAFE 57, 2002).

Analogue Tachographs: A Brief History
Note: Since May 2006, Analogue Tachographs are being phased out in favour of digital versions which record data on a smart card. Find out more about Digital Tachographs.
A tachograph displays vehicle speed and makes a record of all speeds during an entire trip. The name 'tachograph' comes from the graphical recording of the tachometer or engine speed.
Analogue units record the driver's periods of duty on a waxed paper disc – a tachograph chart. An ink pen records the engine speed on circular graph paper that automatically advances according to the internal clock of the tachograph. This graph paper is removed on a regular basis and maintained by the fleet owner for government records.
In the 1950s, there were an increasing number of road accidents attributed to sleep-deprived and tired truck drivers. Concerns for safety led to the rapid spread of the tachograph in the commercial vehicle market, but at this point it was voluntary and not legislated.
Fleet operators then found that tachographs helped them to monitor driver hours more reliably, and safety also improved. In Europe, use of tachographs has been compulsory for all trucks over 3.5 tonnes since 1970.
For safety reasons, most countries also have limits on the working hours of drivers of commercial vehicles. Tachographs are used to monitor drivers' working hours and ensure that appropriate breaks are taken.
Legislation relating to Tachographs has been in force in the UK for 16 years. The tachograph is now an indispensable tool for managing fleets and ensuring the safety of drivers of commercial vehicles.
