What is P2 HD?
P2 HD is a full production-quality, high-definition recording system that utilizes removable solid-state memory cards. This approach eliminates the mechanical wear and environmental limitations of tape, hard disk and optical-disc-based systems. P2 HD ensures the highest reliability, especially in challenging conditions of extreme temperature, shock and vibration. P2 HD products provide a significant reduction in maintenance costs, longer useful product life and immediate access to recorded video (no need to digitize, ingest or create proxy video files) and metadata. Compatible with PCs and existing file-based IT infrastructures, P2 HD content is recorded as independent frames, can be randomly accessed and easily transferred to, or archived onto, low-cost consumer media such as hard drives or other affordable current IT storage technology and future-based systems. P2 HD systems offer long record times and can be upgraded with higher capacity cards.
How does P2 record?
P2 cards record the same way that digital still cameras record onto memory cards — they store the footage as pre-digitized computer files. Instead of recording the video as "video data," they record the footage as computer data files. These files are instantly editable and can be transferred to other computer storage media directly, without the restrictions of needing proprietary video decks or having to wait for real-time transfers. In fact, you can edit footage directly from a P2 card, without having to transfer to a computer at all. Because P2 cards record in universally interchangeable MXF data files, they are immediately usable by properly configured Windows and Macintosh computers. The P2 cards eliminate the need for VTRs, eliminate the need for proprietary video hardware to read or transfer their contents, and eliminate the need to "capture" or "digitize" your footage.
As for the actual recordings themselves, P2 cards record footage in the MXF (Material eXchange Format), a SMPTE-codified cross-platform universal file format. The MXF files use operational pattern OP-Atom, which means that each element of the footage (the audio tracks, the video footage, an "icon" or thumbnail and the descriptive metadata) gets stored in its own sub-directories. The MXF file format is supported by nearly every major nonlinear editing program, while file conversion utilities exist to convert MXF files into other types of files, if needed.
The P2 card itself uses the FAT32 file system, which makes the card compatible with both Macintosh and Windows systems.
What is DRS (Dynamic Range Stretch)? When should I use this tool?
DRS (Dynamic Range Stretch) is a fully automated dynamic range expansion tool that will compress highlight information, and boost shadow detail. It happens simultaneously, on a sector by sector basis - in realtime - at the push of a button. It is a great tool to use in "Run-and-Gun" situations where controlling lighting and dynamic range is very difficult. Daytime exteriors with rapidly changing conditions are a prime target for this tool. DRS should be avoided when you have all of the right tools (Lighting, Grip) to control and carve out a specific look. Its automated functionality will quickly conflict with your abilities to predict and create a consistent specific look for your scenes (adding shadow detail where you intentionally tried to omit it). This functionality is available on select cameras, including the AJ-HPX2700, and the AJ-HPX3100.
Which codec should I choose? AVC-Intra 100 or DVCPRO HD? What about AVC-Intra 50?
If QUALITY is the defining factor, always shoot in AVC-Intra 100, as long as your Post Production facility is equipped to handle that codec. If CONTENT is more important, and achieving extended record times and bandwidth efficiencies rank higher than absolute picture quality, then AVC-Intra 50 should be explored. DVCPRO HD is a good option for those unable to shoot in the AVC-Intra Codec because of legacy post production issues, but it is an 8 bit Codec, which is inferior to AVC-Intra 100's 10 bit Mastering Quality Codec.
What do the various GAMMA MODES represent? What's the difference between HD, VIDEO-REC, FILMLIKE and FILMREC?
GAMMA Mode selection is akin to picking a film stock for your camera. The GAMMA curve you select will determine the video signal output generated by the camera, for varying degrees of luminance input. HD, VIDEO-REC, and FILMLIKE 1 & 2, are fairly punchy, and contrasty curves that are ideally suited for live broadcast applications (News, Sports, Reality/Contest shows,etc...). They are "Air-Ready" and don't require any post processing to achieve full dynamic levels (0% black to 100% white). FILMLIKE 3 and FILM-REC, provide a wider dynamic range and latitude to the camera as well as a more linear transfer curve, but usually at the cost of a flatter, less punchy image, that needs to be Color Corrected in Post. This setting is ideal for applications that already follow this type of workflow, such as Narrative Features, Episodic Television, Music Videos and Commercials.
P2 Card
What's inside a P2 Card?
P2 cards are high-precision micro-computers with their own processors, firmware, a RAID controller, and gigabytes of the highest-quality zero-fault solid-state memory chips. A P2 card is an intelligent device that manages the data files — and even does a write-verification step for every byte of memory that gets written to the card (thus assuring fault-free operation). Early P2 cards were manufactured using actual SD memory cards in a striped RAID array, thus increasing the performance far beyond any individual memory chip's speed. The newest generation of P2 cards dispenses with using individual SD memory cards and actually uses the core memory components.
What sizes of P2 Cards are available?
P2 card are offered in 16GB, 32GB and 64GB sizes.
Whats the recording capacity of P2 Cards?
To establish a P2 card's recording time, you have to determine two factors: what recording format you will use and what capacity of P2 card you're planning on using. The calculation is quite simple after that.
 - For DVCPRO or DV, the data rate is 4 minutes per gigabyte
 - For DVCPRO50 or AVC-Intra 50, the data rate is 2 minutes per gigabyte
 - For DVCPRO HD or AVC Intra 100, the data rate is 1 minute per gigabyte
A 32GB P2 card is capable of storing more than two hours of DVCPRO footage (32 gigabytes × 4 minutes per GB), more than one hour of DVCPRO50 (32 GB × 2 minutes per GB), or 32 minutes of AVC-Intra 100 or DVCPRO-HD.
Please note, even more storage capacity is available in DVCPRO-HD 720P and AVC-Intra 720P and 1080P modes. Please review the P2 HD FAQs document [pdf] for further information.
What is the transfer speed of the P2 Card?
Today's E-Series P2 cards are capable of a transfer rate of 1.2 Gbps. This makes it fast enough to ooffload a 16GB P2 card with at least 16 minutes of DVCPRO-HD or AVC-Intra content in under 2 mintues, or, an 8 to 1 ratio. Please note, many P2 formats and frame rates offer more storage per card. For example, when shooting 1080/23.98p AVC-Inra 100, a 16GB E Series card will hold up to 22 minutes of content. This means that youcan offload these 22 minutes in under 2 minutes, or, an 11 to 1 offload ratio. E Series P2 cards are super fast. Even first generation P2 cards, with a 640 Mbps offload speed or second generation A Sires P2 cards (with an 800 Mbps offload speed) have the ability to offload at a slighter higher speed, through the use of the Panasonic AJ-PCD35 P2 Drive. As always, transfer speeds of IT storage device are subject to hardware configurations.
And, because there are no moving parts and no read/write heads to move or reposition, there's no "seek time" – switching from one stream to the next is instantaneous. Because of the high-speed design of P2 cards, they can be used as an edit media. In other words, there's no requirement to transfer the footage off of the cards before editing: you can actually edit immediately right from the cards.
Can I put 1080I and 720P AND/OR standard definition footage on the same P2 card?
Yes, you can freely inter-mix any type of footage. You can put high-definition and standard-definition, 625 (PAL) and 525 (NTSC), DVCPRO and AVC-Intra, interlaced or progressive or variable-frame-rate footage, or any combination of formats and frame rates all on the same P2 card. Remember, P2 cards are treated by the system as removable storage devices – they don't care what type of information gets stored on them. This gives you an unprecedented amount of freedom and flexibility to work with any format or media as you see fit.
Can a P2 card be used in all P2 HD and P2 camcorders, recorders and drives?
Yes, the P2 card is interchangeable across the entire P2 HD/P2 lineup of products. Any P2 card can be used in any P2-compatible device

Introduction: How to Make Portable Speakers With PET Bottles
Environment-friendly and cheaper alternative
- One can make his/her own speakers without buying expensive ones from the electronics store. Just look for old desktop or stereo speakers (preferrably with a diameter of approx. 2.5 inches).
- The speakers can be utilized either indoors or outdoors due to its compact size and ease of use.
Step 1: STEP 1
- Gather the following materials:
1. two (2) small speakers (with a diameter of approximately 2.5 inches) attached to a 3.5mm jack
2. wire cutter
5. small Phillips screwdriver
6. two (2) identical PET bottles with a diameter of 2.5 inches on their widest inner area on the top halves
Step 2: STEP 2
- Use the cutter to slice the bottle into two.
- The horizontal ridges on the top half of the bottle can be used as guides. One can adjust where to cut according to his/her requirements.
Step 3: STEP 3
- Remove the bottle cap. Detach the wires from the one of the speakers with the scissors.
- Insert the wires of the other speaker through the neck of the bottle and carefully pull them out of the mouth, with the speaker's front facing the open bottom of the top half of the bottle.
Step 4: STEP 4
- If there are any sharp edges on the metal support of the speakers, slowly fold them inwards with the wire cutter. Fit each speaker snugly on the top ridge, near the neck of the bottle.
Step 5: STEP 5
- Using the cutter, cut through the center of the bottle caps with one horizontal line and the other one vertical, forming a "+" sign. Slowly pull outwards the four flaps that were formed by the cuts. Insert the wires through the caps, and twist the latter back on the necks of the bottles.
- Reattach the other speaker to the cut wires.
Step 6: STEP 6
- The speakers are ready for use.

We report details of the fluid motion formed within and above grooves when a laminar continuous phase fluid flows over a second immiscible fluid enclosed in a grooved microchannel. Vortical structures within the transverse grooves were caused by a slip velocity at the fluid-fluid interface and act as "fluid bearings" on the boundary to lubricate the flow of the continuous phase. We investigated the drag reduction in the laminar flow in the microchannel by measuring slip at the boundaries and calculating an effective slip length, taking into account the influence of the effect of the viscosity ratio of the two fluids on the effective slip length. The "fluid bearing" effect can be used to transport high viscosity fluids using low viscosity fluids trapped in cavities to reduce drag.

What are the coordinates of the color Desert Sand?
237, 201, 175.
Sand? Some would say sand. However, the person who gives that answer is a bit uneducated about the desert. Sand is not difficult to sell in the desert. Normal desert sand is unsuitable for construction purposes so coarser, cleaner sand must be imported for making concrete. Desert sand is much too fine and contains a lot of dust, salts and other impurities that make it useless for construction.

Standard fuzzy systems suffer the "curse of dimensionality" which has become the bottleneck when applying fuzzy systems to solve complex and high dimensional application problems. This curse of dimensionality results in a larger number of fuzzy rules which reduces the transparency of fuzzy systems. Furthermore too many rules also reduce the generalization capability of fuzzy systems. Hierarchical fuzzy systems have emerged as an effective alternative to overcome this curse of dimensionality and have attracted much attention. However, research on learning methods for hierarchical fuzzy systems and applications is rare. In this paper, we propose a scheme to construct general hierarchical fuzzy systems based on the gradient-descent method. To show the advantages of the proposed method (in terms of accuracy, transparency, generalization capability and fewer rules), this method is applied to a function approximation problem and the result is compared with those obtained by standard (flat) fuzzy systems.


Ballast Resistors, Resistance and Coils
What is a Ballast Resistor and what does it do and why?
A Ballast Resistor is an electrical device that reduces voltage to the coil so that more energy is available for the spark plugs during starting.
Why would a Ballast Resistor be fitted in a car?
Traditionally, ignition systems didn't use a ballast, meaning that the ignition system used a 12v coil with a 12v feed from the battery via the ignition switch.
This system is fine when the engine is running, however can be problematic when starting. Because the starter motor draws a huge amount of current from the battery, the spark plugs are left with less energy to create the spark. This is worsened in colder starting temperatures or when the starter motor is worn, when even more energy is drawn by the starter motor leaving even less available for the spark plugs.
To counteract this distribution of energy, ignition systems were changed to use a 9v coil instead of a 12v coil. A 9v coil gives the same output as a 12v coil when provided with a 12v feed, resulting in a better spark for starting with less energy draw on the starter motor.
Once the engine is running, the 12v feed is cut and the coil continues to run on the 9v feed.
Which coil should I use if my car has a ballast resistor?
Using a non-ballasted coil would mean that you are running a 12v coil on a 9v feed, resulting in a weak spark. You can however use such coils provided you remove the ballast resister.
Never try to run a ballasted coil when a ballast resistor is not present in the ignition system!
Can I fit a Powerspark Electronic Ignition Kit if I have a ballast resistor?
If you have a ballast coil installed with a ballast resistive wire or a ceramic block then you can keep the coil as it is, there is no need to change it BUT if you change the coil you do need to match it to a ballast if one is present and not bypassed.
Some customers report that bypassing the ballast resistor by disconnecting the ballast feed wire ( from the starter solenoid or built into the loom) and providing a direct 12 volt feed from the starter solenoid/relay or fuse box to the ignition coil has proved to be a success and has given good results.

Impacts due to Density Current Deposition in Reservoirsby Jiahua Fan,
Document Type: Proceeding Paper
Part of: North American Water and Environment Congress & Destructive Water
Different flow pafterns of density currents in reservoirs are discussed. In delta region, lateral density currents from non-stratified flow in the main channel occurs resulting in floodplain deposits with silt and clay. Density current deposition downstream of the topset bed forms wedge-shaped deposit along the reservoir. When a density current reaching the dam under backwater effect, muddy lake deposit may occur before the dam with adverse impacts.

Simultaneous wireless power and information transfer (SWIPT) in a cognitive radio (CR) network is considered where a multiple antenna energy harvesting (EH) secondary receiver (SR) harvests the energy using the antenna switching (AS) technique. In fact, the AS technique selects a subset of the SR antennas to decode the information (namely the information decoding (ID) antennas) and the rest to harvest the energy (namely the EH antennas). In this context, we propose a thresholding-based antenna selection strategy, termed as the prioritizing data selection (PDS) scheme, which selects the ID antennas such that the received power from the secondary transmitter (ST) at these antennas is above a certain threshold. For this scheme, we derive the analytic expressions of the probability mass function (PMF) of the selected ID antennas, the average harvested energy, and the outage probability. In the simulation results, we illustrate the performance of the PDS scheme and we compare it to the prioritizing energy selection (PES) scheme which selects the EH antennas such that the received power from ST at these antennas is above a certain threshold. For both schemes, we show that there is a tradeoff between the outage probability and the average harvested energy.

Semilogarithmic plot
h = semilogy(...)
semilogy plots data with logarithmic scale for the y-axis.
semilogy(Y) creates a plot using a base 10 logarithmic scale for the y-axis and a linear scale for the x-axis. It plots the columns of Y versus their index if Y contains real numbers. semilogy(Y) is equivalent to semilogy(real(Y), imag(Y)) if Y contains complex numbers. semilogy ignores the imaginary component in all other uses of this function.
semilogy(X1,Y1,...) plots all Yn versus Xn pairs. If only one of Xn or Yn is a matrix, semilogy plots the vector argument versus the rows or columns of the matrix, along the dimension of the matrix whose length matches the length of the vector. If the matrix is square, its columns plot against the vector if their lengths match.
semilogy(X1,Y1,LineSpec,...) plots all lines defined by the Xn,Yn,LineSpec triples. LineSpec determines line style, marker symbol, and color of the plotted lines.
h = semilogy(...) returns a vector of handles to lineseries graphics objects, one handle per line.

Today we are in the year
CE. If we count backwards, we reach the year 0. Between the year 0 and today is a time of history called the Common Era or CE. The year 0 is the start of the Common Era. If we keep going backwards past the year 0, we get into a time of history called Before Common Era or BCE. For example, 2560 BCE means 2,560 years before the beginning of the Common Era. This is a time when ancient Egyptians lived. And long before the ancient Egyptians, there was the fabled continent of Atlantis.


Supporting nonbreaking spaces in headings
I recently ran into some issues with some headers not being parsed by CommonMark and the issue turned out to be caused by non-breaking spaces. The current specification defines a space as U+0020 and the requirements for a header are:
a string of characters, parsed as inline content, between an opening sequence of 1–6 unescaped # characters and an optional closing sequence of any number of unescaped # characters. The opening sequence of # characters must be followed by a space or by the end of line.
The reason why non-breaking spaces sometimes get entered is simple: on a Mac you type Option+3 to create a hash and to create a non-breaking space it's Option+Space. This means that if you're still holding down the Option key (usually when typing quickly) and you hit space, you're going to be entering an character which is incompatible with the CommonMark specification. For obvious reasons it's impossible to tell the difference between a non-breaking space and a regular space (without breaking out a hex editor), so it's often hard to tell where the issue lies - other that knowing that something is causing your heading to not parse.
Is it at all possible that the definition of either a space, or a heading, could be updated to allow non-breaking spaces?
4 Likes
I'd second this proposal. For UK keyboards (and likely others) it's easy to create broken headings as '#' is Option+3, so if you are slow to raise the option key between '#' and 'space', you'll get '# ' which won't create a heading.
As @danielsamuels says it's pernicious as you can't visually tell what's going on. I had to break out hexdump.

My concern is that this is really quite Mac specific?

VERA-C is a research project that investigates vortex encounters with curved vortices. It is funded by the German Research Foundation.
In the 1970s, the ICAO introduced vortex related separation minima to prevent severe vortex encounters. These separation requirements have proven to be safe, buth are also considered conservative. They limit airport capacities and are becoming a limiting factor for future air traffic growth. The impact of a separtion minima revision are assess via risk analysis that is based on fast-time Monte Carlo simulations.
Existing simulation models for risk assessment model vortex wakes as straight lines. In reality, vortex wakes deform quickly, break up and form to so called vortex rings. Vortex deformation is mainly triggered by atmospheric turbulence and by a phenomenon referred to as Crow-instability.
The objective of VERA-C is to analyze the impact of vortex distortion on vortex encounter severity by means of risk analysis. The strength of a vortex encounter, specifically vortex induced upsets of aircraft attitude and flight path, is mainly influenced by vortex circulation and encounter geometry. Initial studies show that vortex deformation also has some affect on the induced disturbance. Depending on the level of distortion, the encountering aircraft upset may degrade compared to an encounter with straight vortices.
As part of VERA-C, analytical models of curved vortices will be set up and implemeted in the departments research flight simulator SEPHIR. Simulator test with airline pilots will provide a data base for the development of vortex encounter pilot control models and for models that describe the pilots severity assessment. These models will then be integrated in a fast-time simulation environment to perform risk analysis based on large numbers (~100.000) of simulated encounters. Sensitivity studies and worst-case analysis will be used to assess the impact of vortex distortion on encounter severity.

Scrap paper was the primary ingredient in Mme. Webster's class' fruit salad this November. The grade 6 students took the challenge of "closing the loop", using waste material to create something new. In this case, they diverted scrap paper from the recycling and used it to make new paper – in the shape of fruits including watermelon and strawberries.
To make homemade paper, students first ripped up the scraps into small pieces, before putting it in the blender with water. Once it reached a smoothie-like consistency, the mixture was filtered, and shaped into whatever their creative minds could think of. Finally, the new paper was rolled out and left to dry.
What a fun way to learn first-hand h ow old things can become new again!

Background: Mixed-methods research (MMR) offers much to healthcare professions on clinical and research levels. Speech-language therapists and audiologists work in both educational and health settings where they deal with real-world problems. Through the nature of their work, they are confronted with multifaceted questions arising from their efforts to provide evidence-based services to individuals of all ages with communication disorders. MMR methods research is eminently suited to addressing such questions.
Objective: The aim of this tutorial is to increase awareness of the value of MMR, especially for readers less familiar with this research approach.
Method: A literature review was conducted to provide an overview of the key issues in MMR. The tutorial discusses the various issues to be considered in the critical appraisal of MMR, followed by an explanation of the process of conducting MMR. A critical review describes the strengths and challenges in MMR.
Results: MMR is less commonly used or published in the fields of speech-language therapy and audiology.
Conclusion: Researchers working in teams can draw on the strengths of different disciples and their research approaches. Such collaborative enterprises will contribute to capacity building. Researchers, SLTs and audiologists are encouraged to make use of MMR to address the complex research issues in the multicultural, multifaceted South African context. MMR makes an important contribution to the understanding of individuals with communication disorders, and in turn, researchers in the two disciplinary fields of speech-language therapy and audiology can contribute to the development of this research approach. MMR is well suited to the complexity of South African contexts and its populations, as it can provide multiple perspectives of a topic.

The differences between sixth form and university
When you get to university, you expect a lot of things to be different from the sixth form. However, some of those things might surprise you. Here are a few differences that the prospectus didn't tell you about.
At university (unlike at sixth form) no one will tell you what to do!
A big difference between sixth form and uni is that unlike at sixth form, you will not be told which parts of your class are important. Neither your lecturer nor your teacher will tell you what you should be writing down. Instead, they will lecture and you will have to scribble away, hoping you have got the important bits covered. In no other aspect of your university education will you be told what to do – unless you ask. No more letters coming home to your parents, or assemblies – it's every student for themselves.
Referencing everything is a huge difference between sixth form and university
The sixth form may or may not have introduced you to this ghastly and frankly evil ritual that is referencing. Regardless, you will have to get used to it! It is basically this horrible stage in the already horrible event of having to write a 4000-word assignment. You are physically unable to write a single word without having referenced the author who wrote that word prior to you including it in your essay, the date that it was originally published, the page number in which you found said quote and the publisher who so kindly published the book in which you are now referencing.
A big difference between sixth form and university is that you will live in the library!
The library of a university will have everything you could possibly need as a student: a place to study quietly, computers, sofas that are just about comfortable enough to sleep on and food. Thus, you will live in the library – what possible reason would you have to leave? Oh yes, lectures of course!
Books piled up and crammed into a room or library
Living hand-to-mouth is a real thing that happens
Many students struggle to handle their finances at university and money becomes really tight. The assumption is parties every night and living it up all the time. However, the truth is that this gets expensive very quickly and soon you will have to figure out your priorities. If this is the case, take some time to budget properly for the essentials and if necessary go speak to the professionals on hand at the university to help you manage your money and finances.
All this can come as a real shock to start but don't worry, we're all in the same boat and you will get used to it.

Am I allowed to add multiple TXT records for a single domain?
I've been asked to add a load of MS= records to domains, but some of the domains already have a TXT record.
Can I just add a new TXT record with the value or should I append it to the existing data?
Multiple TXT DNS records are perfectly acceptable. In fact, I think one of my domains has about 6 of them. If you append it to the end of another TXT record, it is likely to stop that one performing it's correct function.
In Amazon's DNS tool, Route53, if you're trying to create multiple TXT values that share the same name, you should surround each value in quotes and separate by a carriage return.

What is it about?
Aquatic invasive species (AIS), such as invasive fish, can spread through waterways. There are several strategies to prevent this, which can be deployed at lock and dam structures within major rivers. Injecting carbon dioxide (CO2) into river water is one such strategy. This method deters AIS from migrating upstream and does not disrupt vessel passage or lock operation. CO2 injection systems are quite effective in small scale, controlled settings. But how do they perform in large navigation lock structures? To find out, researchers assessed the design and performance of a system deployed in the Fox River in Wisconsin.

Why is it important?
CO2 injection in water can prevent the spread of AIS at navigation pinch points. The authors of this study assessed the performance of floor based and wall based CO2 injection manifolds in lock structures. They also studied the mixing time, mixing efficiency, injection efficiency, and power requirements for each system. Both manifolds performed well in preventing fish from entering the lock chamber or forcing resident fish downstream. Multiple concentrated manifolds met the performance requirements of locks that allow movement in one direction. Distributed manifolds performed best in locks that allow movement in both directions. These findings can help inform the effective design and operation of CO2 injection systems in the future. KEY TAKEAWAY: CO2 injection using a system of different manifolds can create a uniform CO2 field in the water. When deployed in navigation locks, this can stop the spread of invasive species.

Bumping is the common name for the process of colliding a ship into another ship or celestial object, resulting in a change of position for the ships involved in the collision.
General Bumping
Bumping can occur when a ship comes out of warp in a position "inside" of the geometry of a Station, Stargate, Ship, Sentry gun, Starbase Forcefield, or other object. The bumping produced can be severe, launching ships at hundreds to even thousands of meters per second away from the other object.
Bumping in Battle
Bumping a targeted ship is common, and typically used to push a ship away from a Stargate to be outside of the maximum jump range (2,500 meters away from the stargate), away from a station to be outside of its docking radius (500 meters), or away from the direction the ship is traveling to prevent it from warping to a celestial object.
POS bowling is an example of an infamous bumping strategy.
EVE's Physics Engine does not calculate damage for collisions, even ships as small as frigates. Frigates can slam into capital ships without negative consequences.
How to
To bump another ship, you can;
 - Set your ship to approach the other ship at high velocity through the right click menu, typically with a MicroWarpdrive running. The MWD increases both speed and mass, making collisions more violent.
 - Manually steer your ship to collide with another ship.

Coventry University and the University of Rwanda host collaborative Summer School on Smart Local Energy Systems
Monday 01 August 2022
As part of the continued growth of Coventry University's Africa Hub, researchers from the Centre for Computational Science and Mathematical Modelling delivered a three-day Internet of Things (IoT) summer school (SSES Rwanda 2022).
The summer school focused on the 'Internet of Things' a concept which defines the connectivity of any device to the internet, and thereby to other connected devices. Led by Professor James Brusey, the school welcomed Masters (MSc) candidates, PhD researchers, and early career researchers from 11 African countries.
The teaching aims of the summer school was to provide participants with the necessary understanding of taking products from concept to deployment, and to gain further understanding of designing wireless intelligent systems in the energy setting.
The summer school was organised in partnership with the University of Rwanda, and the Energy Revolution Research Consortium, with the support of the African Centre of Excellence in Energy for Sustainable Development, the African Centre of Excellence in IoT and the East African Institute for Fundamental Research.
It was such a transformative experience working with Postgraduate Researchers from across Africa. By sharing insights into the process and challenges of going from system concept through to real life IoT deployment, we could explore more critically how this knowledge can be applied to real-world scenarios in the sub-Saharan context.Professor Elena Gaura, Theme Director, Data Science and Emerging Technologies
The summer school opened in June 2022, following the Commonwealth Heads of Government Meeting (CHOGM) in Rwanda. CHOGM welcomed Coventry University delegates and world leaders including Prince Charles, to build productive and meaningful relations between commonwealth countries.
The summer school programme included a variety of interactive workshops, keynotes, and practical sessions to enhance understanding of how the IoT can be applied in the design of Smart Energy Systems.
Smart Energy Systems are imperative to deliver cleaner and cheaper energy services for more prosperous and resilient communities nationwide, offering greater resilience and flexibility for all. These systems benefit the national energy system as an entirety, with an estimated 2 trillion dollars a year invested globally in the transition to low carbon power, transport, heat and localised, digitally connected energy systems.
The feedback from the summer school was exceedingly positive, with many attendees commenting on the value of sharing knowledge across disciplines and with their peers.
The summer school taught me how we can optimise energy. I was introduced to Contiki, an open-source operating system, as well as emerging communication technologies which will be important in my field of work.Teleza Kanthoga, Msc. in the IoT, Malawi
Since my research involves how IoT can help farmers to monitor their farm activities remotely, I got to learn the latest trends, activities and applications in Internet of Things which can be beneficial to my research.Kazeneza Micheline, PhD in the IoT, Burundi

This blog post will answer the question, 'How to prevent a car engine from revving by itself?', and cover topics like reasons behind a car engine revving on its own, symptoms of a car engine revving on its own, and why does a car engine rev on its own?
How to prevent a car engine from revving by itself?
The following preventive measures can be taken up to prevent a car engine from revving by itself:
- The checking of spark plugs should be carried out regularly as they are directly linked to the car ignition system working optimally. It should be noted that the spark plugs should not be dirty or covered with carbon deposits.
- The fuel filter is also one of the crucial components that need to be checked regularly as a clogged fuel filter can cause serious problems and must be replaced immediately.
- A car oil change should be done once around every 3 months or so. This is because an optimum supply of oil will help keep other vital components intact by providing optimum lubrication.
Reasons behind a car engine revving on its own
These are the following reasons that contribute to a car engine revving on its own.
Faults in the ignition system
This is one of the main reasons behind a car engine revving on its own while driving. Therefore, in case the spark plugs are not working properly, the ignition system is to blame as it causes engine misfires.
Defective fuel line
A defective fuel line is another reason behind a car engine revving while driving. It basically signifies that inadequate fuel is being sent to the engine for combustion and thus causes the engine to rev on its own.
Defective fuel pump
A defective fuel pump fails to send sufficient fuel to the carburetor or the fuel injectors of the engine and thus results in improper combustion. It is indicated by a banging noise from under the car hood.
Faulty idle control valve
The idle control valve helps to regulate the idling speed of the car by opening and closing as per requirements. But, if this valve is stuck open and does not budge, it will lead to the car engine revving on its own.
Faulty EGR sensor
The EGR valve is also known as the exhaust gas recirculation valve. It helps to recirculate the exhaust gases back to the combustion chamber of the engine instead of releasing them into the atmosphere.
The EGR valve might get clogged due to the buildup of dirt, dust, gunk, etc. This can lead to the car engine revving on its own, due to inadequate air entering the combustion chamber.
A faulty throttle position sensor
The throttle position sensor or the TPS helps to keep a check on how much the accelerator pedal is being pressed, following which it sends this information to the electronic control unit(ECU).
If this sensor becomes clogged due to dirt, dust, or gunk buildup and starts to malfunction, it can lead to the car engine revving on its own while driving even if the accelerator pedal is not engaged at all.
Defective fuel injectors
Fuel injectors play a crucial role in the optimum combustion of the air-fuel mixture by injecting the fuel into the combustion chamber at the right time.
These fuel injectors can also get clogged at times due to the buildup of gunk, grime, etc. This will lead to improper combustion and the car engine will start revving as the power produced is inadequate.
Faulty oxygen sensor
The oxygen sensor helps in keeping tabs on the volume of uncombusted oxygen present in the combustion chamber after the exhaust gases have been discharged.
If there is an inadequate volume of uncombusted oxygen inside the chamber, and it cannot be used for further combustion cycles, it might cause the car engine to rev on its own while driving.
Symptoms of a car engine revving on its own
These are the following identification signs for a car engine that is revving on its own.
Engine misfires are a telltale sign of your car engine revving while driving as the engine fails to carry out combustion of the air-fuel mixture in one or multiple cylinders. This also causes the car to decelerate all of a sudden and feel sluggish.
In case of the car's idle speed is irregular or the car feels sluggish while idling, this is indicative of the car engine revving on its own while driving.
Why does a car engine rev on its own?
These are the following reasons behind a car engine revving on its own:
- Faults in the car ignition system
- Defective spark plugs
- Defective fuel line
- Faulty fuel pump
- Faulty idle control valve
- Faulty EGR sensor
- A faulty throttle position sensor
- Defective fuel injectors
- Faulty oxygen sensor
Research has shown why cars running on automatic transmission face jerking motions in the event of changing the gears.

This blog post addressed the question, 'How to prevent a car engine from revving by itself?'
We understood the different reasons behind a car engine revving on its own, and also came across the various identification signs for a car engine revving on its own. Furthermore, the primary contributing factors for a car engine revving have also been discussed. Please feel free to comment on the content or ask any questions in the comments section below.
Frequently Asked Questions(FAQs): How to prevent a car engine from revving by itself?
What does it mean when your car keeps revving?
The problem likely lies in a faulty mass airflow sensor(MAF) or a faulty oxygen sensor, this causes the engine to produce less than the required power and thus start revving on its own while driving.
Why does engine rev up and down while driving?
These are the following causes of an engine revving up and down on its own while driving:
- Defective spark plugs
- Defective MAF sensor or air control valve
- Vacuum leakage
What does a car engine revving on its own mean?
A car engine that is revving on its own occurs when the vehicle suddenly feels sluggish and the engine is not able to produce sufficient power for optimum performance.

The Real Reason Oranges Are Sold In Red Mesh Bags
Just because you don't see commercials for oranges on TV doesn't mean that they aren't being expertly marketed to you. According to HuffPost, the way food looks is extremely important, and in fact, it's a billion-dollar business. Essentially, foods need to look tasty, no matter what you're selling. This means lots of research has gone into making everything about the store as profitable as it can be. Everything from where products are placed on shelves to food packaging is all designed to pull you in.
Oranges, in particular, generally come in distinctive red mesh bags, and this was not a random decision on the part of the grocery industry. As it turns out, color is one of the most effective tools that the markets have. In fact, a study found that companies can use colors to "increase or decrease appetite, enhance mood, calm down customers, and reduce perception of waiting time" (via Emerald Insight).
So, which of these does the red bag do?
Selling oranges in red bags has to do with color theory
The red bag actually makes the oranges look, well, orange. If you think about it, the brighter orange an orange or tangerine looks, the riper we interpret it to be. A yellow orange can be instantly written off as unripe. That's the theory behind the red bag — by placing the thin, overlapping lines of red mesh over the oranges, they appear to be less yellow and more orange in color, which makes us interpret them as being of a higher-quality (via Mental Floss). This means you're more likely to purchase a whole bag of oranges than, say, just a few that are stacked by themselves (since those won't look as bright), which in turn means more money for the supermarket.
It's so effective that if you were to put some lemons in the same red mesh bag, they would appear much more orange. This is also why lemons are usually sold in yellow or green mesh bags — to make them look as yellow and green as possible, respectively (via Reader's Digest).
How to see beyond the red mesh bag when buying oranges
What does all this mean for your buying decisions? After all, it's one thing to know the red bag secret, but how can you really tell which oranges are the ripest if the color can't be trusted?
Buying local and organic is always a good way to beat the system and ensure high-quality produce. If you can't make it to the farmers market, though, there are still a few tricks you can use. Taste of Home recommends squeezing the fruits to look for firmness, "heft" (the heavier they are, the more juice they contain), and a thinner skin to suss out the sweetest oranges. There should be a smoothness to the rind and no obvious soft spots. Finally, don't forget to stock up between mid-winter and early spring to get oranges in season.


Disqualifying Offenses
The District shall obtain criminal history record information on final candidates for employment. All District positions have the potential for contact with students. The District shall disqualify from employment a person whose criminal history indicates that the person poses a threat to students or employees. Consistent with business necessity, the District shall also disqualify from employment a person whose criminal history is otherwise inconsistent with the job duties of the position for which the person is being considered.
Individualized Assessment
The District shall perform an individualized assessment of criminal history record information when determining a person's eligibility for employment in a specific position. The District shall take into account a variety of factors, including the following:
The nature of the offense;
The age of the person when the crime was committed;
The date of the offense and how much time has elapsed;
The adjudication of the offense (e.g., whether the person was found guilty by a trier of fact, pled guilty, entered a no contest plea, or received deferred adjudication);
The nature and responsibilities of the job sought;
The accuracy of the person's disclosure of his or her criminal history during the selection process;
The effect of the conduct on the overall educational environment; and
Any further information provided by the person concerning his or her criminal history record.
The fact of an arrest alone does not establish that criminal conduct has occurred, and the District shall not disqualify a person based solely on an arrest. The District may make an employment decision based on the conduct underlying the arrest if the conduct makes the person unfit for the position in question.
SBEC Notification
If a candidate for a position has a reported criminal history, and the candidate is certified by the State Board for Educator Certification (SBEC), the District shall report the criminal history to SBEC.
Credit History
The District shall obtain credit history information on a candidate for employment only when the credit history is related to the position for which the person is being considered. The District shall comply with the Fair Credit Reporting Act before obtaining a job-related credit history. [See DBAA(LEGAL)]

Filtering sequences
The filter expression is used to filter sequences. Filters are commonly used in combination with path expressions to create more precise selectors.
Context item expression
Before you can get started with filters, you'll need to know what a context item expression is and how it works. It is a very simple expression, but very useful while filtering sequences.
The context item expression consists of a single dot ("."). It evaluates to the context item. It will raise a dynamic error (XPDY0002) if the context is absent.
Context item expression example
XQuery

Filter expression
A filter expression consists of a base expression and a predicate. The base expression will be evaluated first. This will result in an input sequence that will be filtered. The predicate is an expression written in square brackets ("[" and "]") and directly follows the base expression. You can identify filter expressions by these square brackets.
Predicate
Since the predicate is an expression, it can be evaluated. It will be evaluated for each item in the input sequence. The predicate is evaluated with an inner focus. This means that:
 - The context item is the item currently being tested;
 - The context size is the number of items in the input sequence;
 - The context position is the position of the context item within the input sequence.
Predicate truth
The predicate may return anything since it is just a regular expression. The result of the predicate is turned into an xs:boolean value. This value is called the predicate truth value. If the predicate truth value is true, the item for which the predicate is evaluated will be kept. If the predicate truth value is false, the item for which the predicate is evaluated will be discarded.
The predicate truth value is determined by applying two rules to the result of the predicate. First, if the result is a singleton atomic value of a numeric type or derived from a numeric type, the predicate truth value is true if the result is equal to the context position, and false otherwise. For all other data types, the predicate truth is the effective boolean value of the result.
Ordering
The ordering of the resulting sequence is the same as the ordering of the input sequence.
Examples
Whew, that was a lot of information. Here are some examples of filter expressions.
Filtering atomic values
This is a short example. The base expression creates a sequence of xs:integer values using a range expression. The filter will keep every item with a value greater than 5. As you can see here, the context item is used to compare the value of each individual item in the input sequence.

Ordering of items
This short example shows that the ordering of items in the input sequence is the same as the ordering in the resulting sequence. The predicate will be false for every value that is an odd value.

Accessing members of a sequence
You may have seen a similar example before. The predicate returns a numeric value. According to the rules for determining the predicate truth value, it is compared to the context position. If it is equal to the context position, the predicate truth value is true, returning the item from the sequence on position two.

text: Abstract:This study presents a numerical investigation of the flow field in a screw pump designed to circulate biological fluid such as blood. A simplified channel flow model is used to allow analysis using a Cartesian set of coordinates. Finite analytic (FA) numerical simulation of the flow field inside the channel was performed to study the influence of Reynolds number and pressure gradient on velocity distribution and shear stresses across the channel cross-section. Simulation results were used to predict flow rates, circulatory flow and the shear stresses, which are known to be related to the level of red blood cell damage (hemolysis) caused by the pump. The study shows that high shear levels are confined to small regions within the channel cross-section, but the circulatory nature of the flow causes an increased percentage of blood elements to pass through the high shear regions, and increases the likelihood of cell damage.


Hot Tar Roof
Hot Tar Roofing Contractors in Houston
Hot tar roofing is popular in Houston due to its ability to reduce energy costs, decrease the demand for routine maintenance, and eliminate the adverse impact of ultraviolet radiation. Professional commercial roofing contractors Houston TX use torches to design watertight layers that can serve you for over 35 years. Depending on your unique requirements, you can also add fire-resistant coatings and a layer made up of minerals that increase the grip of the hot tar roofs surface. The sheets are strong and enable the roof to withstand hail and fast-moving winds. Are you looking for a durable and fuss-free roofing system? As you can see, you have all the reasons to consider hot tar roofing.
Best Way to Install Hot Tar Roofs
Step 1: Prepare for Emergencies
If you are an expert roofer, you have to train your team of workers in first aid. You should also have access to cold water on the site to help in case of burns. Whenever tar comes into contact with the skin, it solidifies. The best way to remove the material is to keep it submerged in water.
To avoid the risk of fire and explosion, you will need to keep your tar kettle 25 degrees or more below the flashpoint. Besides, flammable objects like wooden tools and rags will need to be far from the kettle. Your kettle will also need to be far away from plants and grass.
Your personal security is also essential. Ensure you have heat resistant-gloves, comfortable clothes, shoes, and safety goggles to protect yourself from burns.
Step 2: Estimate the Required Tar Amount
Measure the roof's dimension and use the findings to estimate the amount of hot tar that you will need. In many cases, people use asphalt roofing tar, but you may need coal tar bitumen if your hot tar roof is significantly slanted with slopes and eaves. You can also collaborate with other experts if you need some help.
Step 3: Create Base Layer
Nail a coating on the roofing system to create the base layer. The best coatings to use are asphalt, elastomeric, or aluminized asphalt. Your coating should be based on the roof's shape and the prevailing weather conditions. For a little extra, you can gravel-embed the coating to make it work as a buffer between the tar and the roof. This is the most suitable way of protecting your roof from intense heat.
Step 4: Transport the Tar
 If you have a large roofing project, the material can be poured from a truck's pipes. For small projects, you can use a steel bucket to transport tar to and from your roof. To be safe, make the bucket ¾ full.
Step 5: Pour Hot Tar
Start pouring the hot tar from the furthest corner. Push the tar in smooth strokes using a fiberglass mop. Cover all the areas. Besides, be sure to keep all the layers thin. Also, ensure that the hot tar does not clump in a single section of the roof, as you roll. Carefully lay tar paper and make not less than three layers.
Remember, the installation process of hot tar roofs requires the service of an expert. If you are one, you will appreciate that these tips make it is easy to do the work. Typically, for every 200 square feet, professional roofers apply about 30 pounds of hot tar.
Easy Routine Maintenance of Hot Tar Roofs
Hot tar roofing has significantly fewer maintenance requirements than others. However, with time, you are likely going to need to repair tiny blisters. Trapped airs that exist below the surface of the roof's layers precipitate these roofing issues. To be able to eliminate the blisters, contractors install additional felt.
Energy Efficiency of Hot Tar Roofing
The hot tar roofing's multi-layers successfully prevent too much heat from penetrating the commercial facility. At the same time, it ensures that warmth does not escape from the structure. As such, the roofing system helps to reduce the cooling cost during the summer. Also, it can reduce the heating cost of commercial buildings during the winter.

Official Answer: Quest Stage == Quest Card
Caleb by e-mail wrote:
you're asking if there is a significant difference between the term 'quest stage' vs 'quest card' and the answer is 'no.' Those terms are used interchangeably. The number of quest stages in play is equal to the number of quest cards in play.
I was hoping there wouldn't be inconsistency within a single set (I understand how words from 2010 and 2015 could end up inconsistent).

Voice over BLE
Bluetooth SDK version 2.6.0 introduces a new software example for Thunderboard Sense (TB Sense) boards, called SoC – Voice over Bluetooth Low Energy (VoBLE). The example can be created directly from Simplicity Studio's Launcher after a Thunderboard Sense is connected to the PC.
The application samples data from the microphone on TB Sense, runs it through a filter and codec, and sends it over the Bluetooth link to a GATT client.
The GATT client application, which can receive the samples from the Thunderboard, is made available as an NCP host code. It can be run on a PC connected to an EFR32 device programmed with NCP - target image. The default location of the VoBLE NCP host app is:
How it Works
The block diagram below summarizes the data flow from the microphone into the Bluetooth link.
Block Diagram
The EFR32 on the TB Sense samples the microphone using the ADC with the sampling rate and resolution configured by the GATT client. The sampled data is then run through a digital filter (if the filter usage is enabled) and coded using ADPCM codec before being sent via the Bluetooth link to the GATT client using notifications.
By default, the high pass filter (HPF) is set as the preferred digital filter. To change the filter type, configure it in the Thunderboard Sense software before compiling. The supported filter types are listed in filter_type_t in filter.h.
/** Filter types */
typedef enum {
 LPF, /**< Low Pass Filter */
 HPF, /**< High Pass Filter */
 BPF, /**< Band Pass Filter */
 NOTCH, /**< Notch Filter */
 PEQ, /**< Peaking Band EQ Filter */
 LSH, /**< Low Shelf Filter */
 HSH /**< High Shelf Filter */
To change the filter and filtering parameters, choose one of the filters listed above and configure the DEFAULT_FILTER -macro.
/** Default filter */
_TAG_ DEFAULT_FILTER \
 { \
 HPF, /** Default filter type */ \
 0, /** Default gain */ \
 100, /** Default frequency */ \
 8000, /** Default sampling rate */ \
 2, /** Default bandwidth in octaves*/ \
On the GATT client side, the application starts by sending the configurations to the TB Sense and idles until audio data is received over notifications. Finally, the received data is saved into a file.
Setting up
To test this solution, you need one TB Sense and one WSTK with any of our EFR32BG/MG or BGM radio boards.
Thunderboard Sense (GATT Server)
 1. Attach the Thunderboard Sense to your PC.
 2. Open Simplicity Studio and select your board (Thunderboard Sense).
 3. Click on the SoC – Voice over Bluetooth Low Energy tile in the Software Examples column to create a new project.
 4. Optionally change the filter type as described earlier.
 5. Build and flash the project to the Thunderboard Sense.
WSTK (GATT Client)
 1. Attach the WSTK (with any radio board) to your PC.
 2. Open Simplicity Studio and select your board (WSTK with any radio board).
 3. Click on the NCP target - Empty tile in the Demos column to run the NCP target code on the board.
 4. Open a command prompt and navigate to.
 5. Run make-command (it is recommended to use mingw32, but cygwin can also work).
 This will create four new folders: build, exe, lst and scripts.
 6. Navigate to the exe-subdirectory. If the compiling was successful, you will see the executable application called voice_over_bluetooth_low_energy_app.exe.
Running voice_over_bluetooth_low_energy_app.exe, you should be greeted by the following help message.
Help message
The program can be configured using the flags shown in the above image. When giving the parameters to the program, all units must be omitted.
Few notes about the parameters:
Saving the Audio into a File
To record audio into an audio file using this ncp-host-application, you will have to provide at least the following parameters (examples in parenthesis):
In the example below, the verbose mode is used with the default settings for both sampling rate and resolution (16 kHz and 12 bits respectively) and saving the audio data in a file called my_audio_file.
Command output
If you have activated the verbose mode, as in the above image, you will get status messages from the GATT client application. The application will stop printing status messages after is has written all the configurations, which in the above image happens after transfer status has successfully been enabled. When the initialization is done, the GATT client (ncp-host) is ready to receive data from the TB Sense.
To start recording and streaming audio data over the BLE link, press and hold TB Sense BTN0 (left button). After the button is pressed, you should see activity on the terminal window, summarizing the transmission progress. All audio data will be saved to a file defined by the output filename -parameter ( my_audio_file.ima in this example ). If a file with a same name already exists, the audio data is appended to the end of that file.
To end the transmission in progress, send a interrupt signal to the application. On Windows OS, a keyboard interrupt signal can be sent with CTRL+C key combination.
Importing to Audacity
(Conversion with SoX explained in the next chapter)
To listen to the audio, you can use a freeware tool such as Audacity to import and decode the data. In Audacity, select File -> Import -> Raw Data and select the audio file you have created. The select VOX ADPCM encoding and write down the sample rate that you used, either 8000 or 16000 Hz. In this example 16000 Hz was used.
Audacity Raw Conversion
After the file is imported, you can listen to it by pressing the Play button on the top left corner. Then, you can export the file to wav format through File -> Export Audio.
Optionally, you can also upload it to Watson's Speech to Text to get a speech transcription of the audio recording.
Watson Speech to Text
Using the Provided Scripts
There are few scripts provided to streamline the process, by using a command line audio editing software called SoX. To use the scripts, install the SoX 14.4.1 on your machine (SoX 14.4.2 has issues when capturing standard output, for that reason it is required to use the previous version). Windows scripts can be found from …\scripts\win -directory.
Executes the voice_over_bluetooth_low_energy_app.exe using the parameters given in the config -file.

set SOX_APP="C:\Program Files (x86)\sox-14-4-1\sox.exe"
Configuration options:
Searches the exe-folder for all files of a specified format and converts them to wav-format using SoX. Works for.ima or.s16 files.
Usage: convert.bat ima --OR-- convert.bat s16
The source code of this project can be found in the Bluetooth SDK, as explained in the Description section.
