Data Acquisition Toolbox
Measuring a Noise Floor Using Custom Trigger Conditions
This example shows how to find and acquire a period of at least 2 seconds of relative quiet that occurs between two signals. This would be useful for applications that need to measure a noise floor and calculate a signal-to-noise ratio.
For this example we will show how to initiate a software trigger when using a custom set of conditions that is more complex than the standard values provided by the TriggerCondition property of Data Acquisition Toolbox™ objects.
Note: This can only be run using the 32-bit version of MATLAB® and Data Acquisition Toolbox™. To learn more about using data acquisition devices on other platforms, see this example.
First, find any running data acquisition objects and stop them. This stops all running data acquisition objects from interfering with this example. This code is usually not necessary outside this example unless there are multiple data acquisition objects running.
if (~isempty(daqfind))
Create the Analog Input Object
Before acquiring any data, we must create an analog input object and specify the channels from which to acquire data.
When executing the following code, you may need to modify it to match your acquisition hardware.
% Create the analog input object and specify the
% channel that data should be collected from.
ai = analoginput('winsound');
addchannel(ai, 1);
Define Trigger Condition Information
We must initialize a MATLAB® structure with the information needed to determine when the custom trigger condition has been met. We look for
 - A signal
 - At least 2 seconds of quiet
% Signal is defined as greater than 0.15 volts.
extraData.signalVoltage = 0.15;
extraData.signalFound = false;
% Quiet is defined as less than 0.04 volts.
extraData.quietVoltage = 0.04;
extraData.secondsOfQuietNeeded = 2;
extraData.secondsOfQuietFound = 0;
extraData.quietFound = false;
We store this information in the UserData property so that it can be accessed and modified by the timer callback.
set(ai, 'UserData', extraData);
Configure the Timer Callback
We use the TimerFcn and TimerPeriod properties to call a MATLAB function at regular intervals while the acquisition is running. We use this timer callback function to examine the incoming data to see if the trigger condition has been met.
NOTE: The timer callback function is shown at the end of this example.
% Make timer period 1/10 of our quiet period.
timerPeriod = extraData.secondsOfQuietNeeded/10;
set(ai, 'TimerFcn', _USER_);
set(ai, 'TimerPeriod', timerPeriod);
Configure the Trigger Properties
We use a manual trigger and configure the object to acquire the data during the quiet period.
By setting the TriggerType property to'manual', data logging will not begin until the trigger function is executed. The timer callback will execute the trigger when the correct conditions have been met.
In addition, we set the TriggerDelay property to a negative value to indicate that we want to log the quiet period data that occurred before the trigger was executed.
set(ai, 'TriggerType','manual');
set(ai, 'TriggerDelay', -extraData.secondsOfQuietNeeded);
set(ai, 'TriggerDelayUnits','seconds');
Configure the Amount of Data to Acquire
We set the SamplesPerTrigger property to indicate the maximum amount of data that the acquisition should log. However, the timer callback will stop the acquisition sooner, if it detects a second signal after the quiet period.
sampleRate = get(ai, 'SampleRate');
set(ai, 'SamplesPerTrigger', 10 * extraData.secondsOfQuietNeeded * sampleRate);
Start Acquisition
Now, we start the acquisition. After calling the start function, the object will be running, but no data logging will occur until the trigger function is executed. As the timer callback executes and evaluates the data, messages will be displayed indicating what has been detected.
 % Wait for trigger to occur and the acquisition to end.
 % Set the timeout to a sufficiently large value.
 wait(ai, 60 * extraData.secondsOfQuietNeeded);
 % If the acquisition ended successfully, plot the available data.
 samplesAvailable = get(ai,'SamplesAvailable');
 [data, time] = getdata(ai, samplesAvailable);
 % If the wait timed out, we end up here.
 % Display a message and stop the acquisition.
 disp(sprintf('Could not find quiet period of %d seconds.',...
Warning: The number of samples requested is not available.
The number of samples returned will be reduced.
First signal found. Waiting for quiet period of 2 seconds.
Quiet period found. Logging started.
Clean Up
When finished, we delete the object and clear the variable from the workspace to free system resources.
clear ai;
The Timer Callback Function
We use the timer callback function to examine the incoming data to see if our trigger condition has been met. When our trigger condition has been met, the trigger function is called to start logging.
type TimerCallback;
% The Data Acquisition Toolbox calls the timer callback function with the
% object and event.
function TimerCallback(ai,event)
% First, we get the information needed to evaluate the trigger condition.
extraData = get(ai, 'UserData');
timerPeriod = get(ai,'TimerPeriod');
sampleRate = get(ai,'SampleRate');
% Then, we look at the data received during the last timer period.
sampleData = peekdata(ai, timerPeriod * sampleRate);
maxValue = max(sampleData);
minValue = min(sampleData);
% Next, we analyze the data received and look for our trigger condition.
% If we have not found the first signal, look for it.
if ( ~extraData.signalFound )
 if ( maxValue > extraData.signalVoltage || minValue < -extraData.signalVoltage )
 % The first signal has been found.
 extraData.signalFound = true;
 fprintf('First signal found. Waiting for quiet period of %d seconds.\n',...
% If a signal has been found, we look for the desired period of quiet.
elseif ( ~extraData.quietFound )
 if ( minValue > -extraData.quietVoltage && maxValue < extraData.quietVoltage )
 % Increment the seconds of quiet that we have seen.
 extraData.secondsOfQuietFound = extraData.secondsOfQuietFound + timerPeriod;
 if extraData.secondsOfQuietFound >= extraData.secondsOfQuietNeeded
 % When the desired quiet period is found, we execute the trigger.
 extraData.quietFound = true;
 disp('Quiet period found. Logging started.');
 % No longer quiet. Reset the seconds of quiet that we have seen.
 extraData.secondsOfQuietFound = 0;
% If the quiet period has been found, look for the second signal.
 if ( maxValue > extraData.signalVoltage || minValue < -extraData.signalVoltage )
 % When the second signal is found, we stop the acquisition.
 disp('Second signal found. Acquisition stopped.');
% Finally, we save the updated information to the UserData property so
% that it will be available for the next execution of the timer callback
% function.
set(ai, 'UserData', extraData);


define(is_hex(S), (?is_digit(S) orelse (S >= $A andalso S =< $F) orelse (S >= $a andalso S =< $f))).
-define(is_bin(S), (S >= $0 andalso S =< $1)).
-define(is_octal(S), (S >= $0 andalso S =< $7)).
It's easy to see why parsing 0xf_f fails, _ is neither a digit nor a letter from a to f. My first instinct was to add the underscore as a possible character to the is_x functions, but that seems wrong. Instead, I added another pattern to function definitions, one that would just drop any _ that would be encountered while parsing these numbers:
tokenize_hex([H|T], Acc) when ?is_hex(H) -> tokenize_hex(T, [H|Acc]);
tokenize_hex([$_|T], Acc) -> tokenize_hex(T, Acc);
tokenize_hex(Rest, Acc) -> {Rest, list_to_integer(lists:reverse(Acc), 16), length(Acc)}.
tokenize_octal([H|T], Acc) when ?is_octal(H) -> tokenize_octal(T, [H|Acc]);
tokenize_octal([$_|T], Acc) -> tokenize_octal(T, Acc);
tokenize_octal(Rest, Acc) -> {Rest, list_to_integer(lists:reverse(Acc), 8), length(Acc)}.
tokenize_bin([H|T], Acc) when ?is_bin(H) -> tokenize_bin(T, [H|Acc]);
tokenize_bin([$_|T], Acc) -> tokenize_bin(T, Acc);
tokenize_bin(Rest, Acc) -> {Rest, list_to_integer(lists:reverse(Acc), 2), length(Acc)}.
As you can see, if we now encounter an underscore, we don't modify the accumulator at all. This in effect strips out all underscores in our numbers. Let's run the tests:
~/r/elixir (master ⚡=) make test_erlang
==> elixir (compile)
Compiled src/elixir_tokenizer.erl
==> elixir (eunit)
 All 198 tests passed.
And it works! Running make clean test shows that nothing else broke. The binaries in the bin folder now support the underscore notation:
~/r/elixir (master ⚡=) bin/iex
Erlang/OTP 17 [erts-6.4] [source] [64-bit] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:false]
Interactive Elixir (1.1.0-dev) - press Ctrl+C to exit (type h() ENTER for help)
iex(1)> 0b1001_0001
145
Finding my way around Elixir's codebase was surprisingly easy. The source files are layed out logically and the code itself is clean and easy to understand.
This also shows how important it is for a project to have a comprehensive test suite. Thanks to the existing specs, it was easy to find the relevant pieces of code I needed to work on.
This exercise resulted in a Pull Request and a slightly different version got merged, so look forward to this feature in upcoming versions of Elixir!

The Tuscobia Trail is a symbol for the development of Northern Wisconsin and is owned by the Wisconsin Department of Natural Resources. Conceived as a railroad line in 1899, construction lasted for 15 years, concluding in 1914 when the rail-line reached Park Falls. For nearly 70 years, the rail, known as the "Omaha Line", served as the lifeblood for the area through logging and farming opportunities, as well as the service industries that developed along the route.
By the 1940s, the decline of the railroad was apparent with logging no longer viable. In 1967, the dismantling of the old wooden bridges began. Citizens surrounding the old railway were interested in turning the grade into a functioning trail system that would serve as a representation of the area's history and provide an opportunity for people to learn about the area and experience the beauty that is available along the route.

Sole Source Suppliers and Escrow. While a sole/single source alliance can benefit both the buyer and the supplier companies through the creation of a more solid business/ partnering arrangement, the downside occurs if the supplier is unable to deliver.
In order to understand the full impact of this"downside", just be reminded of any recent problem you have had obtaining product from your sole source supplier.
What measures can be taken to protect our companies from these downside possibilities? While contracts are limited in their abilities to "solve" a problem, they can be helpful in addressing the issues to facilitate a solution.
Consider requiring that your supplier establish an escrow account in which the supplier deposits all designs, manufacturing data, processes, etc. necessary to manufacture and support the product. In addition, and if the bill of material for the product includes purchase of certain proprietary products, the supplier would deposit authorization that the buyer be able to purchase these proprietary products from third party suppliers. The contract would grant your company a license to use all the information in the escrow account if the supplier does not perform its contract obligations.
Keep in mind that in order to be able to effectively use this information, your company might likely first require technical understanding of the products. If that is the case, your contract will want to obligate the supplier to provide access to and training in the understanding and use of the information and data during the actual contract performance.
- Employee Issues: Confidentiality; Ownership; Nonsolicitation; Noncompete
- Confidentiality. The issue of confidential information and the employee's responsibility is two pronged. The first prong relates to that confidential information which the employee either develops or learns in the course of his or her employment with the company.
In general, state laws provide that an employee may not, either during or after his employment, divulge or use trade secrets which were developed by him during his employment or divulged to him by his employer, even absent an express agreement. The rationale is that a employee is in a relationship of trust and confidence with the company. In addition, most companies require that their employees sign an agreement which acknowledges that the employee will maintain the confidentiality of the company's trade secret information both during and after employment.
The problematic aspect of this issue is raised when the employee wants to go to work for a competitor of the employer. The employee should be aware that under appropriate circumstances, the ex-employer may prevent the employee from going to work at a competitor if the following three factors are found to exist:
(1) The former employee has knowledge of the first employer's trade secrets;
(2) The employee's new job duties (and the products and technology he is working on) are so similar to those in the former position that it would be extremely difficult for him not to rely on or use the first employer's trade secrets; and
(3) The former employee and the new employer cannot be depended upon to avoid using the trade secret information.
The second prong relates to that confidential information provided by a third party to the employee's company.
In those cases in which the employer signs a non-disclosure agreement to maintain the trade secrets of a third party, the employee -as an agent of the recipient company - is bound to the non-disclosure agreement and must abide by the confidentiality provisions. Failure to do so may subject both the company and the employee to damages.
- Ownership of Intellectual Property. If a work was created by an employee as part of his or her job, the law considers the product a work for hire, and the employer will own the intellectual property rights to that work, as explained above. A work for hire is defined as "a work made by an employee within the scope of his or her employment".
In many instances, the courts have considered the intellectual property rights to a product developed by the employee to belong to the employer when the employee used company resources in developing the product, even if the employee's development was done outside working hours.
- Non-Compete and Non-Solicitation Agreements. The non-compete clause prevents the ex-employee from working for a competitor or going into a business which competes with his or her ex-employer. The non-solicitation clause restricts the ex-employee from soliciting the business of the ex-employer's customers or suppliers.
The enforceability of these provisions vary by state. For example, in most employee/employer circumstances, California does not recognize the enforceability of a non-compete clause. Even in those states that do enforce non-compete provisions, the clauses must be narrowly written such that they are reasonable in time and geography limitations. The enforceability of the clause generally revolves around the underlying question of: Is there a legitimate business purpose for such restriction? In the absence of a sound business reason, the courts are reluctant to enforce a non-compete clause.
The non-solicitation clause will come under similar scrutiny in terms of reasonable time period and location, but is more often enforced by courts. A non-solicitation agreement may restrict the ex-employee from doing business with a supplier or customer of the ex-employer for a certain period of time.

Cambridge, UK and San Jose, CA (PRWEB) January 06, 2012
CSR plc today announced the availability of the SiRFstudio TM Client LoCoMo API, which gives developers the tools to add location, as well as context-awareness of pedestrian motion, on any MEMS-enabled Android device.
LoCoMo API innovations are based on the concept of "Locomotion" allowing the differentiation between different modes of physical movement, such as walking and running. These capabilities can be used to distinguish applications in a number of categories, such as gaming and physical fitness. The LoCoMo API Software Developer Kit (SDK) comes with a fitness applet called "GoRun" developed by CSR to illustrate LoCoMo API capabilities.
"CSR sees a strong desire on the part of application developers to bridge the physical and virtual worlds," said Ashu Pande, General Manager and Managing Director, Infrastructure and Services Business Unit (ISBU) of CSR. "Developers of games increasingly demand a means of incentivising physical activity with virtual rewards, and fitness application developers would like applications that can sense motion and classify and quantify physical activity throughout the day -- not just during exercise routines."
"With the SiRFstudio Client LoCoMo API, CSR is giving developers the benefit of our deep expertise in location and related signal processing so they may create compelling, differentiated applications," he added.
LoCoMo API offers alternative location determination by providing Cell ID/Wi-Fi positioning when GPS is unavailable by utilising CSR's cloud hosted Cell/Wi-Fi® Access Point Position Database and Motion (i.e. device heading, pitch, and roll) sensing. The LoCoMo API's "Locomotion Context" capability is a significant advance over existing mobile phone pedometer APIs that force developers to assume a static human stride length. This approach creates significant error in the calculation of distance travelled, calories burned and other related values.
In contrast, the LoCoMo API automatically recognises if the user is walking, fast walking, jogging, running, ascending/descending floors via stairs or elevator/escalator, and varies stride appropriately. The LoCoMo API uses the gait context information, which can change constantly during the course of an exercise routine, to provide accurate calculation of distance travelled, calories burned and more. In addition, automatic classification of physical activity simplifies application user interface by reducing the need for users to manually identify their activity.
Interested developers may request access to the LoCoMo API/SDK by contacting CSR at LoCoMo(at)csr(dot)com

Light vehicle: Example, how to calculate your vehicle licence fee
In the following example, a 12 month renewal is applied to a standard motor car (Tare weight: 1,650 kg - the weight of the unladen vehicle):
|Calculate your light vehicle licence fee||Fee calculation|
|Vehicle fee per 100 kg x Total weight (rounded up to the nearest 100 kg) / 100||$23.64 x (1,700 kg / 100) = $401.88|
|Plus prescribed flat fee $13.20 (12-month renewal: (discounted rate) = $6.60)||$6.60|
|Total vehicle licence fee (rounded to the nearest five cents)||$408.50|
- Prescribed flat fee for a vehicle for a period of one year is $13.20 discounted 50%.
- Any vehicle renewal term less than 12 months; calculation will be $13.20 divided by 12 then multiplying by the number of months in respect of which the renewal is paid.
- 6-month renewal: ($13.20/12)*6 = $6.60.
- 3-month renewal: ($13.20/12)*3 = $3.30.
- GVM = Gross vehicle Mass. kg = kilogram. cc = cubic centimetre, engine displacement.
- kW/t = kilowatt per tonne, 1 m² / S³.

text: Field sensors were deployed to determine tidal creek flow measurements and their associated turbidity changes during flood and ebb cycles. These measurements can aid in our understanding of sediment transport and possible accretion patterns occurring in Meadowlands wetlands. The study detected a clear tidal discharge asymmetry of the marsh drainage system. It has been suggested that these tidal discharge asymmetries occur as a consequence of drainage basin morphology and storage characteristics in conjunction with prevailing tidal range and stage (Boon 1975). In this study we use GIS to determine general basin morphology and storage characteristics of five tidal creek basins and compare these with the corresponding stage velocity curves. If there is a strong correlation between landscape metrics, properties, sediment transport, and accretion; then we could use landscape metrics to monitor and predict accretion rates without having to actually measure sediment transport.

Several installations in the Defenses of Washington, the ring of forts built around Washington, D.C., to protect the federal capital during the Civil War, were located close to and in Alexandria.
Unlike Fort Ellsworth and Fort Ward, which were positioned on higher inland elevations to the west, Battery Rodgers was located along the Potomac River, just south of the existing city limits.
Battery Rodgers was named for George W. Rodgers, a U.S. naval captain who was killed in 1863 during an attack on Fort Wagner at Charleston, S.C. Battery Rodgers was strategically positioned on a bluff at Jones Point, on the western side of the Potomac with Fort Foote, located about two miles south on the opposite side in Maryland. In this location, Battery Rodgers was able to guard against Confederate ships on the Potomac and enemy approaches by land to the south.
Plans for the water battery, as it was sometimes referred to, included a 185-foot-long main face, five 200-pounder Parrott rifles, one 15-inch Rodman gun, and two magazines. In this 1864 photograph, the door to one of those magazines is visible on the left, as is the Rodman gun. The gun was large enough for a person to crawl inside it and at least one man was photographed inside doing so. Additional facilities for this fortification included barracks, a mess hall, prison, hospital and slaughterhouse.
No remains of Battery Rodgers exist today, but markers along the waterfront and at the intersection of South Lee and Green streets recall its history.

Photochemical processing is an important way to transform terrestrial dissolved organic matter (DOM) but was rarely investigated by ultra-high resolution mass spectrometry. We performed an irradiation experiment with water from a shaded forest stream flowing into a lit reservoir. Bacterial activity explained only 1% of dissolved organic carbon (DOC) decline in a combined bacterial and photodegradation approach. Photodegradation decreased the DOC concentration by 30%, the specific ultraviolet (UV) absorption by 40%–50%, and fluorescence intensity by 80% during six days. The humification index (HIX) decreased whereas the fluorescence index (FI) did not change. Two humic-like components identified by parallel factor analysis (PARAFAC) of excitation–emission matrices followed the decrease of fluorescent DOM. Changes of relative peak intensities of Fourier transform-ion cyclotron resonance mass spectroscopy (FT-ICR MS) elemental formula components as a function of cumulated radiation were evaluated both by Spearman's rank correlation and linear regression. The FT-ICR MS intensity changes indicate that high aromatic material was photochemically converted into smaller non-fluorescent molecules or degraded by the release of CO2
. This study shows the molecular change of terrestrial DOM before the preparation of drinking water from reservoirs.

Strawberry shortcake is a beloved dessert that has become a summertime staple in the United States. It is a mouthwatering treat that combines the sweetness of fresh strawberries with the fluffiness of a homemade cake and the richness of whipped cream. This delightful dessert is not only visually appealing but also irresistibly delicious, making it a favorite among people of all ages.
What is Strawberry Shortcake?
Strawberry shortcake is a classic dessert that consists of three main components: the biscuit-like shortcake, fresh strawberries, and whipped cream. The shortcake is a tender, crumbly, and slightly sweet cake that forms the base of the dessert. It provides a sturdy foundation for the juicy and vibrant strawberries that are typically sliced and mixed with a touch of sugar to enhance their natural sweetness. The final component is a dollop of fluffy whipped cream, adding a creamy and light element to the dessert.
The combination of these elements creates a harmonious balance of flavors and textures. The sweet and slightly tangy strawberries complement the buttery richness of the shortcake, while the airy whipped cream adds a delightful smoothness to each bite. This classic dessert is often served during summer gatherings, picnics, and barbecues, as it showcases the fresh and abundant strawberries that are typically available during this season.
Preparing strawberry shortcake is relatively simple and can be done in just a few steps. To begin, you will need to gather the ingredients for the shortcake, which include flour, sugar, butter, baking powder, salt, milk, and vanilla extract. The dough is then mixed and shaped into individual biscuits that are baked until golden brown.
In the meantime, the strawberries can be prepared by washing, hulling, and slicing them. A sprinkle of sugar can be added to enhance their natural sweetness and macerate the berries, resulting in a juicy and syrupy texture. The whipped cream is made by whipping heavy cream, sugar, and vanilla extract until soft peaks form.
Once all the components are ready, it's time to assemble the strawberry shortcakes. Split each biscuit in half horizontally, creating a top and a bottom. Spoon a generous amount of strawberries onto the bottom half, allowing the syrup to soak into the cake. Top it off with a dollop of whipped cream and place the other biscuit half on top. Serve immediately, and for an extra touch, you can garnish with a fresh strawberry or a drizzle of chocolate sauce.
With a preparation time of around 30 minutes, cooking time of 15-20 minutes for the biscuits, and servings that can vary depending on the size of the biscuits, strawberry shortcake is a versatile dessert that can be easily adjusted to accommodate a small or large gathering. It is best enjoyed fresh, while the biscuits are still warm and the strawberries are at their juiciest. This delightful dessert is perfect for enjoying with friends and family on a warm summer day, and it will surely leave everyone craving for more.
History of Strawberry Shortcake
Strawberry shortcake, a beloved classic dessert, has a long and fascinating history that dates back centuries. This delightful treat has evolved and transformed over time, becoming a staple in many cultures around the world.
The earliest known references to strawberry shortcake can be traced back to the 16th century. During this time, English and European settlers brought their love for sweets and pastries to the United States. Strawberry shortcake quickly gained popularity, especially during the summer months when fresh strawberries were abundant.
One of the earliest recorded mentions of strawberry shortcake is found in an English cookbook dating back to the 1580s. This cookbook describes a simple recipe consisting of a sweet biscuit-like cake, topped with fresh strawberries and cream. The combination of the buttery cake, juicy strawberries, and luscious cream was an instant hit.
Over the years, strawberry shortcake became deeply ingrained in American culture. It became a traditional dessert served during summer picnics, backyard barbecues, and Fourth of July celebrations. Families and friends would gather to share this delectable treat while enjoying the warm weather and bountiful harvest of strawberries.
Today, strawberry shortcake continues to be a beloved dessert in the United States. While the basic recipe remains the same, there are countless variations and adaptations. Some prefer to use sponge cake or angel food cake instead of the traditional biscuit, while others experiment with different fillings or toppings. Regardless of the variations, the essence of strawberry shortcake remains the same – a delightful combination of juicy strawberries, fluffy cake, and creamy goodness.
Whether you enjoy it at a fancy restaurant or make it at home for a casual get-together, strawberry shortcake is a dessert that brings joy and nostalgia to anyone who takes a bite.

C# Job System tips and troubleshooting
When using the Unity C# Job System, make sure you adhere to the following:
Do not access static data from a job
Accessing static data from a job circumvents all safety systems. If you access the wrong data, you might crash Unity, often in unexpected ways. For example, accessing MonoBehaviour can cause crashes on domain reloads.
Note: Because of this risk, future versions of Unity will prevent global variable access from jobs using static analysis. If you do access static data inside a job, you should expect your code to break in future versions of Unity.
Flush scheduled batches
When you want your jobs to start executing, then you can flush the scheduled batch with JobHandle.ScheduleBatchedJobs. Note that calling this method can negatively impact performance. Not flushing the batch delays the scheduling until the main thread waits for the result. In all other cases use JobHandle.Complete to start the execution process.
Note: In the Entity Component System (ECS) the batch is implicitly flushed for you, so calling JobHandle.ScheduleBatchedJobs is not necessary.
Don't try to update NativeContainer contents
Due to the lack of ref returns, it is not possible to directly change the content of a NativeContainer. For example, nativeArray[0]++; is the same as writing var temp = nativeArray[0]; temp++; which does not update the value in nativeArray.
Instead, you must copy the data from the index into a local temporary copy, modify that copy, and save it back, like so:
MyStruct temp = myNativeArray[i];
temp.memberVariable = 0;
myNativeArray[i] = temp;
Call JobHandle.Complete to regain ownership
Tracing data ownership requires dependencies
See in Glossary
to complete before the main thread can use them again. It is not enough to check JobHandle.IsCompleted. You must call the method JobHandle.Complete to regain ownership of the NativeContainer types to the main thread. Calling Complete also cleans up the state in the safety system. Not doing so introduces a memory leak. This process also applies if you schedule new jobs every frame that has a dependency on the previous frame's job.
Use Schedule and Complete in the main thread
You can only call Schedule and Complete from the main thread. If one job depends on another, use JobHandle to manage dependencies rather than trying to schedule jobs within jobs.
Use Schedule and Complete at the right time
Call Schedule on a job as soon as you have the data it needs, and don't call Complete on it until you need the results. It is good practice to schedule a job that you do not need to wait for when it is not competing with any other jobs that are running. For example, if you have a period between the end of one frame and the beginning of the next frame where no jobs are running, and a one frame latency is acceptable, you can schedule the job towards the end of a frame and use its results in the following frame. Alternatively, if your game is saturating that changeover period with other jobs, and there is a big under-utilized period somewhere else in the frame, it is more efficient to schedule your job there instead.
Mark NativeContainer types as read-only
Remember that jobs have read and write access to NativeContainer types by default. Use the [ReadOnly] attribute when appropriate to improve performance.
Check for data dependencies
In the Unity ProfilerA window that helps you to optimize your game. It shows how much time is spent in the various areas of your game. For example, it can report the percentage of time spent rendering, animating or in your game logic. More info
See in Glossary
window, the marker "WaitForJobGroup" on the main thread indicates that Unity is waiting for a job on a worker thread to complete. This marker could mean that you have introduced a data dependency somewhere that you should resolve. Look for JobHandle.Complete to track down where you have data dependencies that are forcing the main thread to wait.
Debugging jobs
Jobs have a Run function that you can use in place of Schedule to immediately execute the job on the main thread. You can use this for debugging purposes.
Do not allocate managed memory in jobs
Allocating managed memory in jobs is incredibly slow, and the job is not able to make use of the Unity Burst compiler to improve performance. Burst is a new LLVM based backend compiler technology that makes things easier for you. It takes C# jobs and produces highly-optimized machine code taking advantage of the particular capabilities of your platform.

How Can Oracle Be Applied in Education Today?
oracle database, database software, Oracle in Education, Oracle in Education, Education Today
Information Technology has literally taken over every sector of the industry today. Computers and computerized devices are used in manufacturing, healthcare, and research, food processing and even education. I.T. resources such as laptops, tablets, Smartphone, intelligent circuits, Wi-Fi transmitters and more are utilized every day to run companies, industrial plants and organizations too. These I.T. resources are divided into hardware and software resources. One of the software resources used is the Oracle database. It is used to store information for future editing, viewing, and retrieval. The Oracle database is used in organizations as well as education centers. Why is it preferred over other database software in the market? Read on to find out.
Characteristics of Oracle database software
Oracle database software can run on all operating software platforms. Examples of these are Windows, Linux, and Mac OSX. It is also compatible with all standard protocols of networking. This database software satisfies all the industry standards applied in the technology sector. Moreover, developers can expect full support in the Oracle database software from manufacturers. This is essential in adding or adjusting the available features of this database software. Oracle also allows online backups for the latest versions. You can cover all the stages of a database development cycle.
Oracle is also capable of storing large databases. Moreover, it can support both numbers and alphanumeric characters in the data it stores. The databases created with Oracle are object-oriented in nature. As a result, this software is versatile and can be applied in companies, manufacturing plants and education facilities. Moreover, this database software allows the use of cursors. This makes it easier for developers to work with it. Security is a major feature in database software today. Oracle enforces this by dealing with each computer transaction independently. This secures the data that is involved in each transaction. Why is Oracle used for student learning computer concepts? Read on to find out.
Why Oracle can be used for education
This database exhibits concepts of database computing that students need to learn so as to fill roles such as being a remote oracle dba. These concepts include:
 1. Consistency
 2. Atomicity
 3. Durability
 4. Isolation
Consistency of data
For a database to stay secure, it needs to be consistent. This means that it should move from one valid state to another without compromising the integrity of the data stored in it. Oracle exhibits this characteristic. Thus, it is used to educate students on the database creation concept.
Atomicity of data
The data involved in a database transaction is viewed by the system as one unit. In this way, the results of a transaction can only take one of two forms. It can be rolled back in its entirety or committed fully. There is no half-way point. This is atomicity of data. It is an important concept of databases that students can learn from Oracle.
Durability of data
After a database transaction is complete, the results are durable. This means that they are able to survive various conditions such as system failure or viral infection. The results of the transactions in an Oracle database are durable and secure. This is another concept that students can learn using Oracle database software.
Isolation of data
The Oracle database program handles each data transaction independently. None is visible to the other or even to other users of the same database. A transaction can only be viewed after it is complete. This is a feature that contributes to data security.
In addition to the above concepts, there are other reasons why Oracle can be used in an educational setting.
Ability to perform effective error correction
This database software allows you to recovery your data efficiently in case of human error. This error can be incorrect entry or improper editing. Oracle saves multiple instances of a database. Therefore, human error can be corrected by backing up to the latest instance.
Ability to perform data recovery
The nature of saving multiple instances of a database also contributes to faster recover of Oracle databases. In case of resource corruption or system failure, you can restore your database by activating the most recently saved instance.
It has a short learning curve
Oracle has a short, comfortable learning curve. Its concepts are easy to grasp. Moreover, it is built such that it can be easily used in various organizations. This makes it ideal database software to use for teaching data storage concepts to students.
Research Methodology
Every year our worldwide group of specialists leads a yearly study of thousands of big business programming sellers by reaching them legitimately on their most recent quarterly and yearly incomes by nation, practical zone, and vertical market. We supplement their composed reactions with our own essential research to decide quarterly and yearly development rates, notwithstanding client wins to find out whether these are net new buys or extensions of existing usage.
Another component of our proactive research procedure is through nonstop improvement of our client database, which stores more than one million records on the venture programming scene of more than 100,000 associations around the globe.
The database gives client knowledge and logical data on what kinds of big business programming frameworks and other significant advancements are they running and their affinity to contribute further with their present or new providers as a major aspect of their general IT change undertakings to remain aggressive, fight off dangers from problematic powers, or agree to inner commands to improve by and large endeavor productivity.
The outcome is a mix of stock side information and request age client knowledge that enables our customers to more readily situate themselves fully expecting the following wave that will reshape the endeavor programming commercial center for quite a long time to come.
Today, it is necessary to teach students some of the fundamentals of I.T. These are the creation, storage and access of data. This is done using database software such as Oracle. A number of reasons why this particular software is effective in education are indicated above. They are comprehensive and applicable in any student facility teaching I.T.
Author's Bio: Andrew Thompson is a remote oracle dba. He has been in this position for five years. In addition to maintaining Oracle databases for organizations, he also teaches the system to students. The characteristics of Oracle normally prepare students for the demanding world of data maintenance. Andrew made a valid contribution to this report.

What is the difference between a cold drink cup and a hot drink cup?
With the acceleration of the rhythm of life, disposable paper cups are increasingly entering people's convenient life? For disposable paper cups, it can be divided into "cold cups" and "hot cups...
Maybe everyone will feel that disposable paper cups are nothing more than cold water and hot water. What is the difference?
According to the material, disposable paper cups can be divided into two types: paraffin cups and PE coated cups:
Paraffin is very stable at 0-5 degrees Celsius, but when it reaches 42-62 degrees Celsius, the paraffin will melt and release harmful substances such as polycyclic fen hydrocarbons, which are a possible carcinogenic chemical substance, so , the paraffin cup can only be used for cold drinks!
PE film is a kind of plastic film, which can prevent moisture, ultra-low temperature and high temperature of 100 degrees Celsius, so it can hold both hot and cold drinks!

Tombs of the sacrificers?
A few tombs share the characteristic of containing a few very specific objects
: full warrior equipment including a sword in its sheath, spear, shield and also a knife or cleaver (butcher's blade) and an axe with an eye handle, together with one or more small buckets, a bronze pan, a toolbox, and fragments of amphorae. One or other of these objects may be missing, depending on the chronology, but the assembly is still remarkable
. The trilogy of weapon(s)-small bucket(s)-axe/cleaver is always found and the general destruction of the weapons is reminiscent of the Gauls' sacred sites.
One of the axes fits perfectly into the wound in the skull of the murdered man discovered at the settlement and this similarity, together with the specific sets of metal objects, could indicate the tombs of sacrificers
. The replacement of the axe with the butcher's cleaver, at a time when hundreds of ewes were ritually slaughtered at the settlement, is another argument for viewing these remains as those of men of religion.

pageant, modern dramatic spectacle or procession celebrating a special occasion or an event in the history of a locality. In medieval times the word pageant had meant the wagon or the movable stage on which one scene of a mystery or miracle play was performed. The pageant was built on wheels and consisted of two rooms, the lower one being used as a dressing room and the upper used as a stage. The word also referred to the complex wooden machine-structures built for the Tudor masque. The modern form of the pageant came into general use in England and America since the production, in 1905, of L. N. Parker's Sherborne pageant in England. Pageants include such celebrations as the Mardi Gras and annual local festivals.

South Side schoolyard transformation mitigates flooding, improves water quality, learning environment and play areas
Space to Grow benefits Mann Elementary in the South Chicago neighborhood
Space to Grow partners officially unveiled a new schoolyard transformation, taking an old barren playground area and converting it into a vibrant place to play, learn and benefit from the power of green infrastructure by soaking up more water.
Metropolitan Water Reclamation District of Greater Chicago (MWRD) President Kari K. Steele and MWRD Commissioners Debra Shore and Kimberly Du Buclet joined Chicago Public Schools (CPS) CEO Pedro Martinez and Space to Grow partners from the Chicago Department of Water Management, CPS, Openlands and Healthy Schools Campaign to celebrate the completion of a new schoolyard at Horace Mann Elementary School, at 8050 S. Chappel Ave. Space to Grow transforms Chicago schoolyards into beautiful and functional community spaces for physical activity, outdoor learning, environmental literacy and engagement with art. The spaces also address neighborhood flooding issues by using special surfaces and design elements to capture more rainwater.
"We are thrilled that in addition to all of what is below the ground that these talented students now have a beautiful space to play above ground," said MWRD President Kari K. Steele. "Thank you to all of the partners and the entire school community that helped build and will maintain this beautiful space."
Mann's schoolyard can hold 271,203 gallons of stormwater per rain event and includes: an artificial turf field, porous playground surfacing, two large rain gardens, a nature-play area, and an outdoor classroom with permeable pavers. The campus renovation reduces basement backups, reduces the load on the combined sewer system and educates students and neighbors about green infrastructure techniques and purpose.
"As a former CPS student who attended neighborhood schools, I truly understand what this beautiful new outdoor space at Horace Mann will mean for student learning and the entire community," said CPS CEO Pedro Martinez.
"The green schoolyard at Horace Mann will incorporate landscape features that capture a significant amount of rainfall, helping keep our water resources clean and resulting in less neighborhood flooding," said MWRD Commissioner Du Buclet. "We thank our Space to Grow partners for their commitment to educating our students and protecting our water environment."
Space to Grow has now completed 27 schoolyards, with three more set to be completed in the fall. These 30 schoolyards bring the grand total of storage volume to 5.6 million gallons per rain event, equal to 8.4 Olympic-size pools or 111,108 bathtubs per rain event.
"Like the students at Horace Mann Elementary School, we have been anxiously awaiting the completion of this state-of-the-art schoolyard – a beautiful place for children to play, which will also capture stormwater, reduce flooding, and improve water quality in our streams and waterways," said MWRD Commissioner Debra Shore. "We hope students and their teachers and families enjoy this wonderful space to grow."

The marathon is instituted in commemoration of the renowned long distance run coming from Marathon to Athens in ancient times. The actual distance for the very first modern Olympic in 1896 is about 40,000 meters. Because marathon race intervals have been preserved, the world record time has slipped by more than 30 %, from 2:55:18 to the recently set record of 2:03:38. Exploring the advancement of times and the factors that contribute to a runner's success is important whether you are in the middle of your first marathon training or seeking to observe what are the ideal marathons to see.
An athlete who breaks a record doesn't always mean that he actually breaks the world record time. The International Association of Athletic Federations (IAAF) needs to ratify and approve it first. This particular international athletic governing panel only began documenting marathon world record times in 2004, and they have founded strict, continually-evolving regulations regarding precisely what events and times count as world stats. A lot of records are not accepted since the standard regulation which was made in 1921 is not followed like the exact distance and the way it should be measured..
One of the most recent changes to the criteria include disqualifications of competitions for inclusion in world record data according to elevation drops, tailwind, or whatever they label "artificially fast time" aspects. Because of this, a record-breaking 2:03:02 time in the Boston Marathon by Geoffrey Mutai of Kenya was recorded as "fastest marathon ever run," but not as a world record breaking time.
Similarly, despite the fact that most women have been running modern marathons since the 1896 Athens Olympics, whenever Stamata Revithi unofficially ran the men's marathon course the day after the standard competition was held, the IAAF continuously make adjustments to what is approved women's marathon times as world record settings. For a woman's world record to be recorded it should happen in an allwomen's event and that's exactly what should happen in January 2012. To date the best time clocked by a woman in a marathon was made by Paula Radcliffe in the 2003 London Marathon and the time was set to 2:15:21.
The latest men's marathon world record was set in September 2011 by Patrick Makau from Kenya; the man ran a 2:03:38 race in the Berlin Marathon. Today, the Berlin Marathon has become the world record mine, with 4,000 runners and eager fans. It's one of the five most favored, best marathons on earth, along with NYC, Boston, Chicago and London.
In the past 100 years, most of you must've noticed how the pace has dropped significantly. Standard pacing for male marathoners currently hovers about 4:45, and race breaks for the best marathon runs shows the 2nd part of numerous marathoners' runs in fact fall by seven seconds. Aside from the athletes, there are some factors that really affects the time record, the weather, the sport itself, the preparation and so on.
If you're seriously into running marathons and other sports and fitness activities, don't forget the importance of nutrition. It's the fuel you need.

If you still don't know the importance of practicing patience, try reading the following explanations so that there is an inner desire to change. Listen carefully, yes!
1. Remember that life is really hard
Everyone must have the same perspective regarding the hardships of living in this world. Life is tough, your job as a human being is to train your adaptability. One of the things that must be trained is the ability to remain patient.
If you can be patient in facing various kinds of obstacles, believe that everything will work out fine. That's because you can accept whatever happens gracefully.
2. Sometimes whatever you expect is not what you expected
You must have a lot of dreams to fulfill, right? This is certainly a challenge for you to fight for it. Besides that, you also have to be able to prepare yourself to be patient when your expectations don't match your expectations.
Therefore it can be concluded that you need to practice patience. The more often you are patient, then anything that is burdensome is definitely not too heart-consuming.
3. You will meet people who have different thoughts
Don't you realize that everyone has a different perspective in seeing a phenomenon? When differences arise, sometimes you will tend to feel hurt because you do not agree with his words and actions.
But remember that it is irreversible and absolute. All you can do is be patient in dealing with all these differences.

4. Remember that patience is the key to success
Previously we mentioned that everyone must expect a success. If you want to achieve this, sometimes you need extra patience. This patience will help you to smooth the path of struggle.
Train the strength of your heart from now on so that later you can survive despite the many ordeals that come without stopping.
5. With the habit of being patient, you will be a wise person
Everyone is required to be wise in dealing with everything. This wisdom will certainly appear within you if you are used to being patient. You will definitely be a legowo person in the face of various obstacles.
You will also understand the fact that the reality of life is really bitter. With patience, you will be able to accept whatever it is without complaining.


What are some examples of formal operational thought?
Quick Answer
An example of formal operational thought would be imagining the outcome of a particular action that has yet to be undertaken. Formal operational thought, in general, involves the ability to think in the abstract, the ability to combine and classify items and the ability to use high-order reasoning skills.

What are some examples of formal operational thought?

Full Answer
Formal operational thought is the type of cognitive activity that occurs within the titular formal operational stage as articulated by Piaget's theory of cognitive development. According to Piaget, the formal operational stage begins at around age eleven. Another example of formal operational thought would be reasoning through word problems, which involve coming to conclusions about hypothetical situations that involve abstractions of physical objects. A key element of the formal operational stage is the ability to make an inference. Someone in this stage of cognitive development should be able to draw conclusions about things they have not actually experienced by considering information presented to them.
Piaget used a test called the 'third eye problem' to determine one's full transformation into the formal operational stage. Piaget asked children where on their body they would put an extra eye and why. Children around nine years old typically answered that the third eye should be located on the forehead. However, children in the eleven year old range typically suggested that a third eye should be placed on the hand for seeing around corners. This answer characterizes the abstract thinking and reasoning which characterizes the formal operational stage.

Shoe Sizes: EU vs US vs UK, How To Know What Fits?
Hello Shoe Lady,
My shoe size in The Netherlands is 43. My search for really nice shoes has taken me far beyond the borders, to the US. I found different size conversion charts, resulting in conversion of my european shoe size to US size somewhere between 10.5 and 12.5. What is the right US shoe size for me?
Hope you can help me out!
Dear Elis,
I am so glad you found me! I am continually MORTIFIED by the bad information given out to women "who leave a larger footprint" by people in the shoe industry who should know better!
The short answer: US size 11.
Here's a little more information:
Take a look at the international size chart here:
Some of the confusion might be that Great Britain uses a women's shoe measuring system similar to that of the USA. Except different. A Euro size 43, US size 11 women's shoe in Great Britain is a UK 9.
Another source of confusion is that one of the most common sizes in the US is size 8. It is close to (actually a bit smaller than, but wider than a US medium so feels about the same) an EU size 8. So shoe people, who should know better, assume if US 8 equals EU 38, then US 9 equals EU 39 and US 11 equals UK 41. On the surface this sounds logical. But it is so wrong. Here's the mathematical back story. In 1374 the King of England decided to base shoe sizes on the length of a barleycorn. Each barleycorn represents a jump from one size to the next. This was refined in 1880 in the USA when Edwin Simpson got all scientific with the inch (I know everyone on the metric system will laugh at this, as silly as barleycorns) and set the standard for US sizing, In his system, still used, 1/3 of an inch equals one full (not half) size difference. But wait, there's more! Unlike EU sizes which have a standard, proportional width that runs comparable to a US wide, US shoe sizes also come in width measurements, narrow, medium, wide, extra wide.
Your best size may be size 11M ( M equals Medium), but I think you need to know more! I strongly suggest you read up on Measuring Your Feet and Understanding Shoe Sizes ( so you will be able to pick the right length, width and shoe shape for your feet. You want to get the right size the first time when you are ordering from another country!
Thanks for asking!

Instruments and methods for soil testing in the conditions of constrained dilatancy
This chapter dwells on the construction of special instruments designed for shear and triaxial tests. In the process of designing an attempt was made to widen the range of their possibilities and avoid errors which may appear due to an inadequate reflection of natural conditions of soil deformation and failure. The Dilatometric Apparatus of Contact Shear (Dacs) is defended by a USSR copyright, certificate _PHONE_ under the name 'Apparatus for measuring contact resistance to shear of dry materials'. Two modifications of the instrument were manufactured, namely: DACS-1 and DACS-2. The DACS-2 instrument is distinguished by a symmetric arrangement of rests and dynamometers on both sides of the carriage. Instruments DACS-1 and DACS-2 ensure step-by-step application of the shearing force, which allows to model conditions of gradual loading of a construction in soil.

For people visiting China for the first time or even the first few times, it can be a bit of an adjustment to initially figure things and not getting too lost in the process. One way to help visitors more easily adjust is with sharing a network with them, here are a few examples and benefits you get from doing so:
- Share over your own network. This could be adding them to one of your existing networks or creating a new network just for them.
- Create a folder for Travel. You can name it whatever is appropriate, such the name of the city being Shanghai, Shenzhen, Beijing and others. Share the folder with them once created.
- Create sub-folders for logistics. This could be one folder for the airport, one for hotels, one for restaurants and other places of interest.
- Add actions for things needed beforehand, such as getting a Visa getting updated or booking the flight.
- Add a note of specific directions, helpful for more personalized perspectives.
- Add websites as appropriate, such as for the hotels or other points of reference.
- Visitors can add comments to any content you've added for additional confirmation.
- Use in your preferred language, including Chinese (s), Chinese (t), English, Japanese, Korean and if visitors are from Europe, have available to use in French, German, Dutch, Spanish, Finnish, Swedish and others.
- Share the network with other people the visitor will be seeing and create folders just for them. This helps to have a central place for uploading and sharing any content beforehand and easily have available when needed.
Additionally, you and others can get started for free with the Basic plan, including the ability to create networks, use the applications and have initial storage for your files.

Brevard College Campus, Brevard, NC
After World War II, Gaines became college architect for the small Methodist college, which (as an undated but probably ca. _PHONE_ clipping from an Asheville newspaper reported) had begun a proposed expansion of the college. Anticipating funding from the Methodist College Advance campaign, the school planned to construct an infirmary, science building, auditorium, two boys' dorms, and a central heating plant as well as to remodel present buildings. Gaines was to take charge of drafting the plans. An undated birdseye view of the campus signed by Gaines shows a formal arrangement of about a dozen buildings, most of them in red brick with classical detailing. Among the first built were the Mary Frances Stamey Memorial Infirmary (1947, Pack Memorial Library Architectural Collection, SA0653) and the Addison Jones Library (_PHONE_), featured in the Greensboro Daily News of Aug. 22, 1947. Work continued for several years. Further research is needed to determine the status and current names of these and others of the campus buildings Gaines designed.

In the village "Mozori kukhna", located in the Turakurgan district, Namangan region, books of the 10th and early 20th centuries were found.
As UzA reports, the name of this village in the books "Jome ul makomat" and "Mavlono Lutfulloh manokibi" is given as "Bozori kukhna".
It was in the house of the late Abdugafur-ota that a chest with rare books was discovered.
"Everyone here is well aware of the name of Abdugafur Khakimov. His ancestors were religious figures with progressive and creative ideas, looking to the future and determined to tirelessly call the people to light and knowledge," the message reads.

This genus contains only a single species. A. minshullae was described in 1994, from Zimbabwe.
It seeks shelter on the southern side of boulders on granite outcrops, it may also be found under rocks and logs in such areas. Reaches a total length of 30mm. This scorpion has two large lateral eyes on each side of the carapace and two medial eyes giving a total of 6 eyes. A. minshullae is yellowish in colouration and does not have a subaculear tubercle. As with many other scorpion genera A. minshullae males are smaller than females. Because of their small size and colouration, UV light detection is the best technique used for locating members of this genus. This scorpion was named in honour of the late Jacqueline Minshull who founded the department of arachnology at the Bulawayo museum in Zimbabwe. It's venom is likely to be potent but not life threatening under normal circumstances. Few collection records for this species indicate that it is a rare scorpion. A. minshullae was previously placed in the genus Lychas.
Because of its small size and distribution, this species is unlikely to be encounted.

union
Class: dataset
(Not Recommended) Set union for dataset array observations
The dataset data type is not recommended. To work with heterogeneous data, use the MATLAB® table data type instead. See MATLAB table documentation for more information.
Syntax
C = union(A,B)
C = union(A,B,vars)
C = union(A,B,vars,setOrder)
[C,iA,iB] = union(___)
Description
C = union(A,B) for dataset arrays A and B returns the combined set of observations from the two arrays, with repetitions removed. The observations in the dataset array C are sorted.
C = union(A,B,vars) returns the combined set of observations from the two arrays, with repetitions of unique combinations of the variables specified in vars removed. The observations in the dataset array C are sorted by those variables.
The values for variables not specified in vars for each observation in C are taken from the corresponding observation in A or B, or from A if there are common observations in both A and B. If there are multiple observations in A or B that correspond to an observation in C, those values are taken from the first occurrence.
C = union(A,B,vars,setOrder) returns the observations in C in the order specified by setOrder.
[C,iA,iB] = union(___) also returns index vectors iA and iB such that C is a sorted combination of the values A(iA,:) and B(iB,:). If there are common observations in A and B, then union returns only the index from A, in iA. If there are repeated observations in A or B, then the index of the first occurrence is returned. You can use any of the previous input arguments.
Input Arguments
A,B
Input dataset arrays.
vars
String array or cell array of character vectors containing variable names, or a vector of integers containing variable column numbers. vars indicates the variables for which union removes repetitions of unique combinations of the variables.
Specify vars as [] to use its default value of all variables.
setOrder
Flag indicating the sorting order for the observations in C. The possible values of setOrder are:
'sorted'Observations in C are in sorted order (default).
'stable'Observations in C are in the same order that they appear in A, then B.
Output Arguments
C
Dataset array with the combined observations of A and B, with repetitions removed. C is in sorted order (by default), or the order specified by setOrder.
iA
Index vector, indicating the observations in A that contribute to the union. iA contains the index to the first occurrence of any repeated observations in A.
iB
Index vector, indicating the observations in B that contribute to the union. If there are common observations in A and B, then union returns only the index from A, in iA. iB contains the index to the first occurrence of any repeated observations in B.

Business Rules (I realize these rules are a little abnormal): A Person (student) can attend multiple schools. Once one or more Schools are chosen, the student can pick one or more degrees at each school. Once a degree is chosen, the Student has an option of choosing to participate in many DegreeSpecificGroups, Courses, and OptionalTrips.
I have 4 tables:
Table Person
Table School
Table Degree
Table DegreeSpecificGroup
Table Course
Table OptionalTrip
Assume that each table has a need for a unique set of properties for each Person. However, I am trying to keep this simple. My question is - where should I keep the relationships with the Person table? Do I make a relationship table for each combination - ie: PersonSchool, PersonDegree, PersonCourse, PersonOptionalTrip...?
I am having troubles convincing myself to do this because it contradicts my hierarchical thinking - IE: you cannot attend an OptionalTrip unless you are enrolled in the School and have selected a Degree. Half of me wants to keep all relationship information in the highest relationship level (SchoolPerson) - but of course that table will become bloated and unmanageable. What is the proper way to handle these multi tiered relationships?
I have looked at some ER diagrams to see some examples of other diagrams but they do not have the level of detail I am looking at enter image description here

 What is the relationship between a school and a person (student?)? If a Person goes to 0 or 1 schools you don't need SchoolPerson. In general, it's difficult to discuss design without knowing the business rules, perhaps you should start formulation sentences like "A student can enroll for 1 or more Courses", "A Course has a degree and is given by a School", etc.

1 Answer 1

You have a Person, who is attending a School? They are studying for a Degree? A Degree will consist of 1 -> many Courses. A Course may be on many Degree programmes (e.g. Foundation Maths)?
The totally general case is that 1 Person can attend 1 or more schools studying for 1 or more Degrees in each school at any one time - is this possible? Some people may be repeating one course but have been allowed to advance, contingent on passing an exam elsewhere?
So, in order to be completely general, you want a Person table, a Degree table and a School table - with Person_Degree being your joining table between Person and Degree and Person and ultimately School. If a Person can only be doing 1 Degree in 1 School at any time, then you can simplify.
You then have a Degree_Course table which will have the joins between Degrees and Courses and a Course table.
Some Degrees can be multi-School - then you'll just have to have a further joining table. However, remember the YAGNI principle - if you don't have a current need, don't include it in your design. This can be difficult to judge - we want our systems to be flexible, but I'm with Einstein on this - make it as simple as necessary but no simpler!
Before a first take on the tables themselves - you could do worse than having a quick look here - you might get some ideas (and I might have even overlooked something! :-) )
Two things to bear in mind - one is that DDL (Data Definition Language) is quite powerful in its own right - right there in the database structure is a lot of "intelligence" - i.e. you can't have a degree without a school or a course without a school! The various other UNIQUE, PRIMARY KEY and FOREIGN KEY constraints enforce other logical rules about the system - rules you would otherwise have to spend a lot of time enforcing in your app!
Finally, a couple of words about table names.
I always use singular names for tables - they are like a class definition and/or a collection - (for me it is a singular concept - you might disagree). As an aside, you have tables in which you might want to have only 1 or even 0 records (think nuclear power plant system with a table called "catastrophic_meltdown"). In any case, choose one convention and stick to it.
Furthermore, my table_names_might_appear_long! :-) It can be greatly helpful when debugging to have meaningful table names - code spends >> 99% of its time in maintenance, so the extra typing is a (very) small price to pay for helpful error messages when things go wrong - and they will, no matter how good a programmer you are!
In PostgreSQL, I would do it like this (should translate reasonably well to other systems - check your documentation for details!) - note that I haven't dealt with semesters/trimesters here - adding a semester field to the degree and course tables might be necessary - again, this depends on your system requirements.
CREATE TABLE person
(
 person_id SERIAL,
 CONSTRAINT person_pk PRIMARY KEY (person_id),
 person_first_name VARCHAR(25) NOT NULL,
 person_last_name VARCHAR(50) NOT NULL
 --
 -- .. other person stuff... address, phone &c.
 -- .. could make f_name + l_name UNIQUE?
);
CREATE TABLE school
(
 school_id SERIAL,
 CONSTRAINT school_pk PRIMARY KEY (school_id),
 school_name VARCHAR(50) NOT NULL
 -- other school stuff
 -- Tel., address... &c.
 --
);
CREATE TABLE degree
(
 degree_id SERIAL,
 CONSTRAINT degree_pk PRIMARY KEY (degree_id),
 degree_name VARCHAR(50) NOT NULL,
 degree_code VARCHAR(10) NOT NULL,
 degree_school_id INTEGER, -- no "NOT NULL, since it is an FK field - see below
 CONSTRAINT degree_school_fk FOREIGN KEY (degree_school_id) REFERENCES school (school_id)
 -- other degree stuff - faculty, prerequisites (another table?)
);
CREATE TABLE course
(
 course_id SERIAL,
 CONSTRAINT course_pk PRIMARY KEY (course_id),
 course_name VARCHAR(50) NOT NULL,
 course_code VARCHAR(10) NOT NULL,
 course_school_id INTEGER,
 CONSTRAINT course_school_fk FOREIGN KEY (course_school_id) REFERENCES school (school_id)
 -- other stuff - possibly a course_prerequisites table
);
CREATE TABLE degree_course
(
 degree_course_id SERIAL,
 CONSTRAINT degree_course_pk PRIMARY KEY (degree_course_id),
 degree_course_degree_id INTEGER NOT NULL,
 degree_course_course_id INTEGER NOT NULL,
 CONSTRAINT degree_course_degree_course_uq UNIQUE (degree_course_degree_id, degree_course_course_id), -- prevent same entry twice
 CONSTRAINT degree_course_degree_fk FOREIGN KEY (degree_course_degree_id) REFERENCES degree (degree_id),
 CONSTRAINT degree_course_course_fk FOREIGN KEY (degree_course_course_id) REFERENCES course (course_id)
);
CREATE TABLE prerequisite
(
 prerequisite_id SERIAL,
 CONSTRAINT prerequisite_pk PRIMARY KEY (prerequisite_id),
 main_course_id INTEGER,
 preq_course_id INTEGER,
 CONSTRAINT prerequisite_uq UNIQUE (main_course_id, preq_course_id) -- prevent same entry twice
 -- other info...
 --
);
CREATE TABLE person_degree
(
 person_degree_id SERIAL,
 CONSTRAINT person_degree_pk PRIMARY KEY (person_degree_id),
 person_id INTEGER NOT NULL,
 degree_id INTEGER NOT NULL
 -- various FOREIGN KEY and UNIQUE constraints to be added here!
);
Similar principles apply to your optionaltrip and degreespecific group tables - if you're having further issues, post back!

Admin Multi-Check is a security feature built into RealmsCore that helps protect your server.
Some commands, such as permissions and moderation commands, use Admin Multi-Check. This means that in addition to the normal permission node (such as realms.kick for the /kick command), they require:
- The realms.admin permission
- If permissions and multi-check are enabled, "admin: true" must be listed below the player's UUID in the playerperms.yml file.
For example, here is an example excerpt from a playerperms.yml file:
# Kyle_Necrowolf's permissions c7a0e7df-5141-4344-b119-9f1102e5178c: admin: true permissions: default: admin_utility cheat: admin_cheat
If the "admin: true" line (bolded above) is not found, the player will be denied access to the command.
Why use Admin Multi-Check
Because this feature is separate from permissions, your server stays protected even if your permissions system is compromised.
"Force op" hacks will fail the multi-check, because they only fool the permissions system. They can't modify the file, so they can't fool RealmsCore.
In most cases, the server owner is the only person with access to the server files. No one on the server can modify or bypass this system, therefore, the owner is always in control.
Disabling Admin Multi-Check
If Admin Multi-Check is disabled, only the realms.admin permission is required. The playerperms.yml file will not be checked.
The console, command blocks, and remote console (RCON) are not affected (see below).
Disabling permissions (in coreconfig.yml) will automatically disable Admin Multi-Check.
Beyond that, it is not recommended that you disable Admin Multi-Check manually. It is a non-intrusive security feature that can help protect your server. However, if you do not want to use it, you can disable it in coreconfig.yml.
How it works with Console, Command Blocks, and Remote Console (RCON)
Admin Multi-Check also applies to commands run from the console, command blocks, and remote console (RCON).
For all commands that use Admin-Multi-Check:
- By default, the console is allowed. Can be blocked in the config.
- By default, command blocks are blocked.
- Can be allowed in the config, but not recommended, as it allows commands to be run without restrictions, and any player on your server can maliciously activate command blocks.
- By default, the remote console (RCON) is blocked.
- Can be allowed in the config, but not recommended, as it can open your server up to remote attackers.
- All other command senders (entities, proxies) are blocked.
Note that this applies even if Admin Multi-Check is disabled. Disabling the feature will only disable it for players.
