Synopsis
Propellor modules
System modules
getTemporaryDirectory :: IO FilePath #
Returns the current directory for temporary files.
On Unix, getTemporaryDirectory returns the value of the TMPDIR environment variable or "/tmp" if the variable isn't defined. On Windows, the function checks for the existence of environment variables in the following order and uses the first path found:
 - TMP environment variable.
 - TEMP environment variable.
 - USERPROFILE environment variable.
 - The Windows directory
The operation may fail with:
 - UnsupportedOperation The operating system has no notion of temporary directory.
The function doesn't verify whether the path exists.
getUserDocumentsDirectory :: IO FilePath #
Returns the current user's document directory.
The directory returned is expected to be writable by the current user, but note that it isn't generally considered good practice to store application-specific data here; use getXdgDirectory or getAppUserDataDirectory instead.
On Unix, getUserDocumentsDirectory returns the value of the HOME environment variable. On Windows, the system is queried for a suitable path; a typical path might be C:/Users/<user>/Documents.
The operation may fail with:
 - UnsupportedOperation The operating system has no notion of document directory.
 - isDoesNotExistError The document directory for the current user does not exist, or cannot be found.
getAppUserDataDirectory #
Arguments
:: FilePath
a relative path that is appended to the path
-> IO FilePath
Obtain the path to a special directory for storing user-specific application data (traditional Unix location). Newer applications may prefer the the XDG-conformant location provided by getXdgDirectory (migration guide).
The argument is usually the name of the application. Since it will be integrated into the path, it must consist of valid path characters.
 - On Unix-like systems, the path is ~/.<app>.
 - On Windows, the path is %APPDATA%/<app> (e.g. C:/Users/<user>/AppData/Roaming/<app>)
Note: the directory may not actually exist, in which case you would need to create it. It is expected that the parent directory exists and is writable.
The operation may fail with:
 - UnsupportedOperation The operating system has no notion of application-specific data directory.
 - isDoesNotExistError The home directory for the current user does not exist, or cannot be found.
getXdgDirectoryList #
Arguments
:: XdgDirectoryList
which special directory list
-> IO [FilePath]
Similar to getXdgDirectory but retrieves the entire list of XDG directories.
On Windows, XdgDataDirs and XdgConfigDirs usually map to the same list of directories unless overridden.
Refer to the docs of XdgDirectoryList for more details.
getXdgDirectory #
Arguments
:: XdgDirectory
which special directory
-> FilePath
a relative path that is appended to the path; if empty, the base path is returned
-> IO FilePath
Obtain the paths to special directories for storing user-specific application data, configuration, and cache files, conforming to the XDG Base Directory Specification. Compared with getAppUserDataDirectory, this function provides a more fine-grained hierarchy as well as greater flexibility for the user.
On Windows, XdgData and XdgConfig usually map to the same directory unless overridden.
Refer to the docs of XdgDirectory for more details.
The second argument is usually the name of the application. Since it will be integrated into the path, it must consist of valid path characters. Note: if the second argument is an absolute path, it will just return the second argument.
Note: The directory may not actually exist, in which case you would need to create it with file mode 700 (i.e. only accessible by the owner).
As of 1.3.5.0, the environment variable is ignored if set to a relative path, per revised XDG Base Directory Specification. See #100.
Since: directory-1.2.3.0
getHomeDirectory :: IO FilePath #
Returns the current user's home directory.
The directory returned is expected to be writable by the current user, but note that it isn't generally considered good practice to store application-specific data here; use getXdgDirectory or getAppUserDataDirectory instead.
On Unix, getHomeDirectory behaves as follows:
 - Returns $HOME env variable if set (including to an empty string).
 - Otherwise uses home directory returned by getpwuid_r using the UID of the current proccesses user. This basically reads the etcpasswd file. An empty home directory field is considered valid.
On Windows, the system is queried for a suitable path; a typical path might be C:/Users/<user>.
The operation may fail with:
 - UnsupportedOperation The operating system has no notion of home directory.
 - isDoesNotExistError The home directory for the current user does not exist, or cannot be found.
setModificationTime :: FilePath -> UTCTime -> IO () #
Change the time at which the file or directory was last modified.
The operation may fail with:
Some caveats for POSIX systems:
 - Not all systems support utimensat, in which case the function can only emulate the behavior by reading the access time and then setting both the access and modification times together. On systems where utimensat is supported, the modification time is set atomically with nanosecond precision.
 - If compiled against a version of unix prior to 2.7.0.0, the function would not be able to set timestamps with sub-second resolution. In this case, there would also be loss of precision in the access time.
Since: directory-1.2.3.0
setAccessTime :: FilePath -> UTCTime -> IO () #
Change the time at which the file or directory was last accessed.
The operation may fail with:
Some caveats for POSIX systems:
 - Not all systems support utimensat, in which case the function can only emulate the behavior by reading the modification time and then setting both the access and modification times together. On systems where utimensat is supported, the access time is set atomically with nanosecond precision.
 - If compiled against a version of unix prior to 2.7.0.0, the function would not be able to set timestamps with sub-second resolution. In this case, there would also be loss of precision in the modification time.
Since: directory-1.2.3.0
getModificationTime :: FilePath -> IO UTCTime #
Obtain the time at which the file or directory was last modified.
The operation may fail with:
Caveat for POSIX systems: This function returns a timestamp with sub-second resolution only if this package is compiled against unix-2.6.0.0 or later and the underlying filesystem supports them.
getAccessTime :: FilePath -> IO UTCTime #
Obtain the time at which the file or directory was last accessed.
The operation may fail with:
Caveat for POSIX systems: This function returns a timestamp with sub-second resolution only if this package is compiled against unix-2.6.0.0 or later and the underlying filesystem supports them.
Since: directory-1.2.3.0
getSymbolicLinkTarget :: FilePath -> IO FilePath #
Retrieve the target path of either a file or directory symbolic link. The returned path may not be absolute, may not exist, and may not even be a valid path.
On Windows systems, this calls DeviceIoControl with FSCTL_GET_REPARSE_POINT. In addition to symbolic links, the function also works on junction points. On POSIX systems, this calls readlink.
Windows-specific errors: This operation may fail with illegalOperationErrorType if the file system does not support symbolic links.
Since: directory-1.3.1.0
pathIsSymbolicLink :: FilePath -> IO Bool #
Check whether an existing path is a symbolic link. If path is a regular file or directory, False is returned. If path does not exist or is otherwise inaccessible, an exception is thrown (see below).
On Windows, this checks for FILE_ATTRIBUTE_REPARSE_POINT. In addition to symbolic links, the function also returns true on junction points. On POSIX systems, this checks for S_IFLNK.
The operation may fail with:
Since: directory-1.3.0.0
removeDirectoryLink :: FilePath -> IO ()

TRIM THE TREE
A holiday game for 1-5 players
by Jeffrey D. Allers
If you like puzzle games, or if you simply enjoy the surprise of seeing what kinds of ornaments are in each box as you decorate your Christmas tree, you might enjoy "Trim the Tree." Play alone or with up to 4 opponents and try to score the most points by having the tree with the most balanced decorations in color and shape.
5 Christmas Tree boards:
5 Star scoring markers:
5 Star scoring markers:
80 Ornament counters (in 4 different shapes and 4 different colors):
1 Ornament Box tile with overview of the scoring:
Each player takes a Christmas Tree and a Star.
Place the Star next to the scoring space marked „0" on the Tree.
With only 3 players, take one set of 16 Ornaments out of the game.
With only 2 players, take out two sets (32 Ornaments total).
If playing solataire, take out 3 sets (or 4 sets for a more calculating version).
Place all the remaining Ornaments in the Bag and give to the starting player.
Place the Ornament Box in the middle.
1) Open a box of Ornaments: the starting player draws as many Ornaments from the Bag as the number of players and places them on the Box.
2) Trimming the Tree: starting with the starting player and continuing clockwise, each player chooses an Ornament from the Box and places it on an empty space on her Tree.
A space is represented by the intersection of 2 or 3 lines on the Tree.
After the first Ornament is placed, players must place each new Ornament on a space adjacent to an Ornament already on her Tree.
3) Scoring: if an Ornament placed completes one or more triangles on the Tree, that player may score points for the triangle(s) if all 3 Ornaments in each triangle are of a different color and shape.
One triangle completed in this ways scores 1 point. If an Ornament completes two triangles, and each of these includes Ornaments of different colors and shapes (but Ornaments of one triangle may match the color and or shape of Ornaments of the other triangle), the two triangles score 3 points. Three triangles completed by the same ornament score 5 points. Four triangles score 7 points. Five triangles score 9 points. And six triangles score 11 points.
See Ornament Box for a summary of the scoring.
Any points scored by completed triangles are marked by moving the Star along the outside of the Tree so that it points to that player's current score.
Example: a player places a blue box ornament that completes two triangles on his tree at the same time. One triangle has a red bell and a yellow candle, the other has a blue bulb and red candle. The first triangle scores because all of the ornaments are of a different color and shape. The second triange does not score because it has two blue ornaments. The player scores 1 point total for the two completed triangles and moves his star one space around his tree. If that player had placed a purple box instead of a blue one, he would have scored 3 points total for both triangles.
Note: a player must always place an Ornament from the Box. The last player in the round does not have a choice as to which Ornament to take.
BEGINNING THE NEXT ROUND:
After the last Ornament is taken from the Box, pass the Bag to the player on the left.
END OF GAME:
When all the Christmas Trees are filled with Ornaments, the game ends. The player with the highest score places her Star on the Tree and wins the game. If there is more than one player tied for the highest score, the tied players share the victory.
The original idea and first prototype originated naturally at Christmastime several years back, when I found some nice wooden bits and Christmas tree-shaped box at a local hobby shop. Seasonal games are notoriously difficult to market, and publishers usually avoid them, so my motivation was strictly personal--to create a fun game for myself, friends and family to play over the holidays. The early version pictured above actually works fine as a game, but did not have the elegance and efficiency I was looking for. So, just as I have done every year this time of year, I brought out the bits and began thinking again about changes I could make. This year, in the interest of improving the design, I finally "let go" of my beautiful bits in favor of cardboard counters (or one could print the ornaments on wooden or plastic chips as well), and I think this is much more "my type of game," if there is such a thing.
And since I doubted a publisher would be interested, I decided to "self-publish" on my blog. Enjoy!

Tutorial: Obtaining Spectra based on Color Constraints
How to Find all Objects with Spectra that Satisfy a Given Set of Color Constraints and then Get the Spectra.
This query, in particular, finds spectra for all objects at the hot end of the WD cooling sequence. For a simple example, this list is defined as objects with g-r <-0.15 and u-g <0.4. Normally, when querying based on filter or color magnitudes, you should also make sure all the appropriate photo QA flags are set properly (to indicate the object's photometry is trustworthy), but in this case, since all these objects have spectra, we will assume they were targeted and allocated a fiber based on good photometric magnitudes, so we don't bother to check the QA flags.
 1. Go to the Spectro Query Server (all data access tools are linked from Data Access in the left navigation bar).
 2. Select "html" as output format if you want to look at your query results in your browser, or "csv" to save them in a "comma-separated values" file which you can use to retrieve spectra from the Data Archive Server later
 3. At the first line, enter 0 to have your query return an unlimited number of output rows/objects.
 4. Select "minimal" under "Spectroscopy Parameters" under "Parameters to Return". This will return the MJD, plate, and fiberID that you will need to actually get the spectra from the DAS. Make sure none of the filters are checked in the "Filter (for DAS use)" section.
 5. Select the Best radio button between the parameter listboxes.
 6. Under Position Constraints, make sure "No Position Constraint" is selected.
 7. Enter 0.4 in the "u-g max" box.
 8. Enter -0.15 in the "g-r max" box.
 9. Unselect "Extended Sources" and make sure "Point Sources" is selected in the "Object Type" section of the form.
 10. Verify that nothing else is selected.
 11. Click on "Submit Request". Depending on database load, this query takes about half a minute to run and returns 3493 objects.
To get the actual spectra for these objects:
 2. Go to the DAS spectroscopic data retrieval form.
 3. Select the data release you for the spectra you want to download. DR7 uses a later version of the pipeline, and includes spectra not included in DR6. Note that if you select "All data" then the rerun you desire must be included in the csv table you upload, and you will need to slightly modify the procedure you use to generate the cvs accordingly.
 6. Follow the link given the "Download selection" section to the form for mass download.
 7. Under "File types," select spSpec. (You might also want spPlotGif if you want to see simple GIFs of each spectrum.) The spSpec selection will get you the FITS file for each spectrum.
 11. See the tutorial on "Displaying SDSS Spectra" to learn how to display your new SDSS spectra.

Hi guys,
So, we are making a project where we use 3 UV sensors.
We want to get the readings of 3 sensors connected together but we want the serial monitor to show only the readings of the highest intensity of the sensors. So whenever one of the sensor is been directed towards the sun we want only that sensor's readings to show up. And we are not sure how to make the 3 sensors all in one code
This is the original code of one sensor
//Hardware pin definitions
int UVOUT = A0; //Output from the sensor
int REF_3V3 = A1; //3.3V power on the Arduino board
void setup()
 pinMode(UVOUT, INPUT);
 pinMode(REF_3V3, INPUT);
 Serial.println("ML8511 example");
void loop()
 int uvLevel = averageAnalogRead(UVOUT);
 int refLevel = averageAnalogRead(REF_3V3);
 //Use the 3.3V power pin as a reference to get a very accurate output value from sensor
 float outputVoltage = 3.3 / refLevel * uvLevel;
 float uvIntensity = mapfloat(outputVoltage, 0.99, 2.8, 0.0, 15.0); //Convert the voltage to a UV intensity level
 Serial.print("output: ");
 Serial.print("ML8511 output: ");
 Serial.print(" / ML8511 voltage: ");
 Serial.print(" / UV Intensity (mW/cm^2): ");
//Takes an average of readings on a given pin
//Returns the average
int averageAnalogRead(int pinToRead)
 byte numberOfReadings = 8;
 unsigned int runningValue = 0;
 for(int x = 0 ; x < numberOfReadings ; x++)
 runningValue += analogRead(pinToRead);
 runningValue /= numberOfReadings;
//The Arduino Map function but for floats
//From: _URL_
This is the original code of the Sensor

Help:Contents import
From semantic-mediawiki.org
This help page explains how the contents import is done with help of the "Importer" feature provided since Semantic MediaWiki 2.5.0Released on 14 March 2017 and compatible with MW 1.23.0 - 1.29.x..1 In short, import is done upon Installation of Semantic MediaWiki from legitimate files located in the directory specified with configuration parameter $smwgImportFileDirsSets the contents import directory for legitimate files to be imported upon Installation of Semantic MediaWiki which are available in the .json format (currently no other formats are supported) and contain the version specified with configuration parameter $smwgImportReqVersionSets the contents import file version for legitimate files to be imported upon Installation of Semantic MediaWiki. After every import maintenance script setupStore.phpAllows to set up the data backend/store has to be run.
Preselected import content is defined in the "vocabulary.json" file and includes "Smw import skos", "Smw import foaf", "Foaf:knows", "Foaf:name" and "Foaf:homepage".
The objective of the Importer is to provide a simple mechanism for deploying data structures and support information in a loose yet structured form during the installation (setup) process.
Import definitions
$smwgImportFileDirs defines import directories from where content can be imported.
Import definitions are defined using a JSON format which provides the structural means and is considered easily extendable by end-users.
The import files are sorted and therefore sequentially processed based on the file name. In case where content relies on other content an appropriate naming convention should be followed to ensure required definitions are imported in the expected order.
Default definitions
Preselected import content is defined in the "default.json" file and includes:
 - "Smw import skos"
 - "Smw import owl"
 - "Smw import foaf"
 - "Foaf:knows"
 - "Foaf:name" and
 - "Foaf:homepage"
It should be noted that default.json is not expected to be the authority source of content for a wiki and is the reason why the option canReplace is set false so that pre-existing content with the same name and namespace is not replaced.
Custom definitions
It is possible to define one or more custom import definitions using $smwgImportFileDirs with a custom location (directory) from where import definitions can be loaded.
$GLOBALS['smwgImportFileDirs']['movie-actor-vocab'] = __DIR__ . '/import/movie-actor';
$GLOBALS['smwgImportFileDirs']['custom-vocab'] = __DIR__ . '/custom';
Fields
JSON schema and fields:
 - description short description about the purpose of the import (used in the auto summary)
 - page the name of a page without a namespace prefix
 - namespace literal constant of the namespace of the content (e.g. NS_MAIN, SMW_NS_PROPERTY ... )
 - contents it contains either the raw text or a parameter
 - importFrom link to a file from where the raw text (contains a relative path to the $smwgImportFileDirs)
 - options
 - canReplace to indicate whether content is being allowed to be replaced during an import or not
The $smwgImportReqVersion stipulates the required version for an import and only definitions that match that version are permitted to be imported.
Examples
XML import
It is possible to use MediaWiki's XML format as import source when linked from the importFrom field (any non MediaWiki XML format will be ignored).
The location for the mentioned custom.xml is relative to the selected $smwgImportFileDirs directory.
{
 "description": "Custom import",
 "import": [
 {
 "description" : "Import of custom.xml that contains ...",
 "contents": {
 "importFrom": "/xml/custom.xml"
 }
 }
 ],
 "meta": {
 "version": "1"
 }
}
{
 "description": "Template import",
 "import": [
 {
 "description" : "Template to ...",
 "page": "Template_1",
 "namespace": "NS_TEMPLATE",
 "contents": "{{{1}}}, {{{2}}}",
 "options": {
 "canReplace": false
 }
 },
 {
 "description" : "Template with ...",
 "page": "Template_2",
 "namespace": "NS_TEMPLATE",
 "contents": {
 "importFrom": "/templates/template-1.tmpl"
 },
 "options": {
 "canReplace": false
 }
 }
 ],
 "meta": {
 "version": "1"
 }
}
Import process
During the setup process, the Installer will automatically run and inform about the process which will output something similar to:
Import of default.json ...
 ... replacing MediaWiki:Smw import foaf contents ...
 ... skipping Property:Foaf:knows, already exists ...
Import processing completed.
If not otherwise specified, content (a.k.a. pages) that pre-exists are going to be skipped by default.

Herb & Honey Compounds
Australerba Herb and Honey Compounds
Australerba Herb and Honey Compounds are a combination of pure unrefined bee's honey and spagyrically prepared extracts from selected herbs species from different parts of the world.
Herbs and honey have been combined as tonics and therapeutic formulae since antiquity. they are nature's gift readily available to mankind and come from the same source, the generous plant kingdom.
Honey is the processed nectar of flowers, a wonderfully balanced energizer and suitable carrier of principles obtained from herbs through our special extraction methods.
They are highly concentrated, syrup like consistency and pleasant to taste. They can be taken from a teaspoon, or mixed with milk, water, fruit juice etc.
At present the following range is available:


Infrastructure at your Service

An Introduction to Pester – Unit Testing and Infrastructure checks in PowerShell
If you never heard of it, Pester is a PowerShell module, written in PowerShell.
It's a framework for writing and running unit tests, integration tests, and also infrastructure checks as we will see in a moment.
Pester is used for example to test PowerShell Core and Pester itself.
In this blog post, I'll do a short introduction to Pester with Installation and basic checks examples.
Pester is shipped by default with Windows 10 and Windows Server 2016. The version installed is 3.4.
The latest version is available in the PSGallery. It is currently version 5.1.
If you have the 3.4 version installed and would like to update it you will face errors with Update-Module. You need to use the following command to get the latest version:
PS C:\> Install-Module -Name Pester -Force -SkipPublisherCheck
PS C:\> Get-InstalledModule
Version Name Repository Description
5.1.0 Pester PSGallery Pester provides a framework for...
PowerShell function example
I will now show you a very basic Pester test.
Let's say I want to write a Pester test for the following PowerShell function.
This is a very basic function that reverses the string characters. This is the output:
Now that I have a working function I can start to write the Pester test.
Create a Pester Tests file
The Pester function New-Fixture will create a template file for me but you could definitely create it yourself.
By convention, Pester test files should end with "Tests.ps1".
The Tests file has been created.
I already edited the file and wrote the test.
This is what a Pester test looks like:
Pester basics
Pester is very declarative and easy to read.
You can ignore the first 3 rows in the Tests file, they came from the New-Fixture function and just dot sources the function to test into the PowerShell session.
The main commands with Pester are Describe, It, Context, and Should.
Describe is a block that contains tests. You will often have one Describe block for each function you want to test.
Context blocks are like Describe, they contain It blocks. They are optional and are useful to organize your test code.
The It block is the one that actually contains the test. The It block should have an expressive phrase describing the expected test outcome.
Finally, the Should command defines the test condition to be met. If the assertion is not met the test fails and an exception is thrown up. I used the -Be parameter. Many more are available like -BeFalse, -BeGreaterOrEqual, -BeLike, -Contain, etc.
In this example the test is simple. I set the expected value that I should get and I compare it to the actual value returned by the function.
Running Pester Tests
Now let's run the test itself with Invoke-Pester.
Also, running Invoke-Pester without any parameter will run all the "Tests.ps1" files in the current location.
So, everything is green. We can see that one test was performed and it Passed.
Now let's say another developer worked on the Get-ReverseString function and the latest change introduced a bug. Function behavior has changed and the Pester test will now throw a beautiful exception:
What is great is all the details (in red color) we can get when a test fails.
Infrastructure Testing
Pester is often used by sysadmin to do infrastructure testing. Your environment changes frequently and you need to be sure that your infrastructure is aligned with your standard.
Here are a few examples of such tests. The test is done directly inside a Pester code block not using a function like I did previously.
Check that my Windows Server Power Plan is set to High Performance.
Describe "Power Plan" {
 $PowerPlan = (Get-CimInstance -ClassName Win32_PowerPlan -Namespace 'root\cimv2\power' | Where-Object IsActive).ElementName
 It "Should be set to High Performance" {
 $PowerPlan | Should -be "High Performance" -Because "This Power Plan increases performance"
The best practice for SQL Server disks is to have an allocation unit size of 64 KB, here is the check:
Describe "File Allocation Unit Size" {
 $BlockSize = (Get-CimInstance -ClassName Win32_Volume | Where-Object DriveLetter -eq $SQLDisk).BlockSize
 It "Should be 64 KB" {
 $BlockSize | Should -Be 65536 -Because "It is recommended to set a File Allocation Unit Size value to 64 KB on partitions where resides SQL Server data or log files"
Here I used the dbatools command Get-DbaErrorLogConfig to get the number of files configured for my ErrorLog. My best practice is to have 30 files instead of 6 by default.
Describe "SQL Server Error Log Files" {
 $errorLogCount = (Get-DbaErrorLogConfig -SqlInstance $SQLInstance).LogCount
 It "Should have Number of Log files set to 30" {
 $errorLogCount | Should -Be 30 -Because "Best practices requires 30 logs files to perform daily recycling"
When all put together the output of the Tests looks like this:
As you can see I can easily validate that my SQL Server infrastructure is configured as expected.
Code Coverage
Code Coverage is the percentage of lines of code that is tested by unit tests.
It's an indicator of how thoroughly your code has been tested. Having 100% coverage doesn't mean that the code is bug-free, it just indicates that all your code is being executed during the test.
If I add some code to my Get-ReverseString.ps1 file, the -CodeCoverage functionality will tell me exactly what is not covered by tests:
This blog post was just to get you started on learning Pester. There are a lot more possibilities with Pester. I might cover some more advanced usages a future post like the TestDrive or Mocking.
Here are some resources I'd recommend:
You can find all the code from this blog post on GitHub.

Tissue classification from electric impedance spectroscopy for haptic feedback in minimally invasive surgery
MetadataShow full item record
Haptic feedback is missing in teleoperated surgical robots creating a sensory disconnect from the surgeon and their patient. This thesis proposes using the electric impedance of tissues, instead of the traditionally used mechanical impedance, to develop haptic feedback for surgical robots. Electric impedance spectroscopy (EIS) and a modified surgical needle were successfully able to measure the electric impedance for gel-based phantoms, ex-vivo tissue, and freshly excised organs. Processes for fitting the electric impedance of these tissues to the double-dispersion Cole model were developed including stochastic and deterministic approaches. The tissues were classified with least square error, k-Nearest Neighbour and Naïve Bayes using the measured electric impedance and the extracted model parameter values. The thesis culminates in applications of using EIS as part of implementing vibrotactile and force feedback applications involving sets of user trials to validate its effectiveness in identifying the tissue through haptic feedback.

Tamarac Refuge offers history tours
In recognition of Minnesota's sesquicentennial, the refuge will present three Discovering Tamarac History tours during the month of July.
These tours will highlight sites related to the logging era, pioneer settlement, the Civilian Conservation Corps, and the early development of the refuge. These first ever refuge history tours provide a unique opportunity to visit selected sites, learn about area history, and imagine how folks survived in the wilderness.
The Discovering Tamarac History tours are a part of a new history initiative by the Tamarac Interpretive Association.
Tours will be presented Saturday, July 12, from 1-4 p.m.; Tuesday, July 15, from 7-9:30 p.m.; Sunday, July 27, from 1-4 p.m. Participants are to meet at the visitor center for a short presentation and then will car caravan to several historical sites.
There will be some walking involved so wear sturdy shoes and don't forget to bring your stories to tell. For more information, please contact the refuge at _PHONE_.
The Tamarac Interpretive Association is a nonprofit organization whose mission is to support the conservation and wise use of the natural and cultural resources of the refuge.
The U.S. Fish and Wildlife Service is the principal federal agency responsible for conserving, protecting, and enhancing fish, wildlife, and plants and their habitats for the continuing benefit of the American people. The Service manages the National Wildlife Refuge System that includes more than 540 refuges nation wide.
Within Becker County, the Service is represented by the Tamarac National Wildlife Refuge, Hamden Slough National Wildlife Refuge, and the Detroit Lakes Wetland Management District. Becker County enjoys an impressive diversity of both plants and wildlife as a result of its location where the eastern deciduous forest meets the prairie.

Liu Liping Xu Baoxiang Wang Zhijun Wang Jun(Lanzhou Institute of Plateau Atomspheric Physics, Chinese Academy of Sciences, Lanzhou 730001 )
This paper presents the calculations of the scattering properties of hydrometeors with different shapes and phases. Based on these properties and ZDR features of rain and clond echos, the dual linear polarization radar RHI data observed during hailstorm processes on August 9 and August 30, 1990 are analysed. We deduced that the area with negative ZDR values corresponded to hail shafts where may appear large oblate hailstones and small conical hailstones, and the area with great positive Z D R values corresponded to raining area. The Z D R greater than 5dB was caused by huge raindrops (D0.5cm). It is possible to detect the presence of hail using ZDR as a criterion. Compared with a S-band radar, the C-band dual linear polarization radar is unique in several aspects : the Z DR values are larger in raining area and smaller and negative in hail shooting area, which are useful for the study of microphysics and spatial structure of storms. The dual linear polarization radar will be impartant to cloud physics and weather modification.

can a spider plant grow in something other that water? (ex: vinegar, liquid jell-o, coffee)

That's a very interesting question! I am thinking the acid in vinegar might be a problem. But jello -- mostly sugar, gelatin, water, and coloring, right? Coffee? Hmm, is the chemical makeup of coffee?
I found a lot of information about spider plants on Google when I typed "Growing spider plants." It seems that maybe too much water could be a problem -- whether it is coffee or jello. So you will need some kind of control -- perhaps distilled water and another control grown in soil. One reference on the web said chemicals are a problem --so you might compare distilled water to water from a creek or even your street after a storm.
A basic scientific approach is to understand the dimensions you are studying (usually called dependent variables). For example -- the amount of water and the properties of the water could affect the growth of the plants. The acidity of the water is another variable.
When you test other liquids such as coffee and vinegar, you'll need to know how they are related, and this will suggest other liquids to test. For example, given that vinegar is acidic, you could also use milk, which is non-acidic (pH > 7). In this case, you'd want to measure the pH of the coffee. This doesn't mean that pH is a critical factor, but it's one of the differences you'll need to consider between the liquids you test.
As another example, jello has sugar in it. So in using jello you might actually be testing how sugar affects the growth of spider plants.
To summarize, you'll need to understand some of the properties of the liquids -- a way to relate them chemically -- or your results will be perhaps interesting, but not tell you anything fundamental about the growth of spider plants.
I hope this is helpful to get started.

Before you start creating jobs on magnetic, let us first discuss what a job is.
Project / Booking / Job/ Order / Case
First off, a job can be renamed to Jobs, Bookings, Orders, or Case.
A job in Magnetic mirrors a project in a company where you have to complete work for a customer or internally over a period of time. A job is always something that has been agreed in principle with a customer or it is agreed internally.
A Job may include all or some of the following:
Private Jobs:
You can create a private job that is only visible to you or to somebody else if you assign them a task in your private job.
When creating a job, simply tick the Private tickbox. Setting to Private will make the job only visible to the users with assigned tasks in the project/job.

What's happening in my country
This page contains specific information about the planning and implementation of smart villages in Sweden. The information aims to orient people on policy planning, key contacts and resources on smart villages. However, it neither aims to be fully comprehensive, nor necessarily reflects the official government or European Commission position.
Explore how smart villages are being implemented in Sweden.
Key CAP contact(s) :
Support for Smart Villages under the Common Agricultural Policy (CAP)
- The preparation of the CAP Strategic Plan and its future interventions is in progress.
- Smart villages will only be included as a possible thematic focus within LEADER, depending on the extent to which the local LEADER strategies are including the concept in their measures. Thus, LEADER will have a supporting role to develop local projects that function as concrete, small-scale smart village initiatives/plans, adjusted to the lo-cal village or community context. In the applications to be approved as LEADER areas, many of the Local Development Plans have special measures for smart villages or are mentioning support to Smart Rural Areas as an objective.
- Broadband and commercial services will not continue to be supported under the CAP. These will be supported through national funding instead.
Key NRN contact(s) :
Activities of the National Rural Network (NRN) on smart villages
- The Swedish NRN runs a thematic working group on 'smart villages' and one thematic working group on 'innovation in rural areas'. They both consist of representatives of national organisations, authorities and associations.
- The working group on 'smart villages' has developed a work plan with activities on financing and advice for smart initiatives, methods for local transition/development plan and translation of materials from the European Network for Rural Development (ENRD) Contact Point, as well as webinars to inspire cooperation between local, regional and national levels.
- The working group on 'innovation in rural areas' has developed a work plan with activities to define and describe methods to guide and promote innovators and innovations, describe innovation infrastructures in rural areas, collect and publish information on good examples and create meeting places and opportunities to exchange experiences of innovations and innovation processes in rural areas.
- The Swedish NRN has had representatives at the ENRD thematic group on smart villages and its meetings.
- As for the future, the Swedish Board of Agriculture suggested that the NRN should play a distinct role within the national coordination of the 'smart villages' concept.
Support provided through other national/ regional policies & initiatives
The 'smart villages' concept is not included as a specific measure or objective in other Euro-pean structural and investment funds, nor national funding programmes. Nevertheless, it will be possible to fund activities and projects that contribute to the development of a smart village through several of these funds, such as the ERDF, the national funds for commercial services and for broadband.

1537
In the never-ending race to the top between Android and iOS, the main culprits have mainly been users. The urge to try out new and wonderful smartphones might have often seen you jump ship either way. However, when you do this, you are likely to encounter a well-known problem. Both types of phones use completely different processing systems. This means that you might be able to smoothly transfer some things. Chief among them is transferring messages from Android to iPhone.
If this is your situation, this article should help. It provides amble ways to copy text messages from Android to iPhone.
Two Best Methods for transferring messages from Android to iPhone
1. Move to iOS
The first way to get this done is by using the official method that was released by Apple. This method works for all Apple phones and devices that use 4.3 upwards. It allows you to transfer a lot of things completely free from your Android to the iPhone.
Step One
The first thing you have to do is to download the application on the Google play store. Once you have done it, install it and run the application on your Android device. Once you have done this, choose the option to move data from Android to iPhone.
Step Two
Make sure it has been launched. Then, make sure your wireless connection and Bluetooth are both switched on, you are going to need it through this process. Do the same for your Apple smartphone and place it side by side. Once you have done this, it's time to move on to the next stage.
Step Three
To make sure that the transfer is authorized by you, you will need to match a code. This code will be sent to both phones and you will have to verify that the codes are the same. Once you do this, then you get to choose what to move and what you can choose not to move.
2. Using Backuptrans
You also have the option of using a tool to get this done. The reason why this method might be more appealing is that you get to transfer a wider range of things including text messages.
To use backuptrans, all you have to do is to install and run the program on your computer. Once you have that figured, you will have to connect your Android and iPhone to the computer. To know about the procedure of using backuptrans, all you have to do is click the link in the first paragraph of this article.
Conclusion
So here's the deal. If you want your messages and other things transferred from Android to iPhone, then you have two really good methods. You can choose to use the official method or use other tools such as backuptrans. Before you make a decision, you should do well to consider the options that are more convenient for you. You should also consider what you want to transfer.
By considering all these variables, you set yourself for future success.

Purpose: To develop a method for estimating the radiation dose to the conceptus from multidetector computed tomography (CT) of the abdomen and pelvis in pregnant patients during the first 7 weeks of gestation.
Materials and methods: This study was approved by the institutional review board and informed consent was obtained. A CT simulation software package was used to (a) develop voxelized models on the basis of image data from 117 nonpregnant patients who underwent abdominal and pelvic multidetector CT and (b) calculate dose at a position of the uterus assumed to be the position of the conceptus in case of pregnancy during the first 7 weeks of gestation. Regression analysis was carried out to establish the relationship among conceptus dose, patient body size, and distance from the conceptus to the anterior skin surface.
Results: Normalized conceptus doses calculated by using the software package ranged from 0.335 to 0.785 mGy per absorbed dose to air. Conceptus dose showed a significant correlation with maternal body size and conceptus depth (R² = 0.793, P < .001). A multivariable correlation of conceptus dose normalized to the free-in-air CT dose index (CTDI(F)) with conceptus depth and patient perimeter was produced for estimating conceptus dose from abdominal and pelvic multidetector CT. Conceptus dose data provided for a specific scanner can be applied to other scanners by using correction factors based on ratios between the weighted CT dose index and CTDI(F), resulting in inaccuracies in the estimation of conceptus dose of less than 12%.
Conclusion: The radiation dose to the conceptus from abdominal and pelvic multidetector CT can be estimated with a method that allows for variations in maternal body size and conceptus position.

Attaching of shifting cables to Aeroad CF frame
The bowden cables of the Aeroad CF are routed inside the frame. This reduces the air drag and the cables are covered from water and dirt. This is how you route the cables inside the frame:
1. The Aeroad CF has built in Liner (long thin plastic tubes). These liners facilitate the routing of the cables inside the frame. They are only to be used to route cables, they do not replace GoreTex cable housings. One bowden cable runs from the left shift lever to the right side of the down tube and the cable of the right shift lever runs to the left side of the down tube.
2. Push the bowden cables through the appropriate liner. Both cables cross inside the down tube. The cable exits the bottom bracket on the side of chainwheel. The cable for the front derailleur exits on the other side of the bottom bracket.
3. Pull both liners out of the down tube. You should keep the liner.
4. Thread the cable through the cable guide fixed underneath the bottom bracket.
5. Now you push the bowden cable for the rear derailleur through the liner inside the chainstay.
6. Pull the liner out of the chainstay. Attach the cable to the rear derailleur.

The answer is found on the following page:
What is the difference between an air tanker and a water bomber?
Air tankers are land-based aircraft which leave the base with a load of fire retardant and must return to the base for additional loads. Water bombers are amphibious aircraft that skim over large water bodies and scoop up water which is then dropped on the fire. The B.C. Forest Service uses air tankers almost exclusively.
All air tankers have basically the same function on a fire, however, some will have more carrying capacity than others.

Homemade plates are typically made from pottery clay and fired in a kiln to ensure long-term strength and durability. Decorations for homemade plates vary, depending on whether the plates are designed to be purely decorative, or if they are intended for practical, everyday use. For homemade plates that will be used as serving dishes, select only decorating materials that are clearly marked as being safe for food.
- Skill level:
- Moderately Easy
Other People Are Reading
Things you need
- Homemade plates
- Food-safe glazes and paints
- Pottery kiln
- Paint brushes
- Potter's wax
Select a food-safe glaze or glazes to decorate homemade plates. Glaze can be applied to homemade plates once they have been kiln fired. Use paint brushes, stencils, sponges or other faux finishing tools, like brushes and combs, to create unusual and organic patterns, such as waves, stripes or curls. Fire the homemade plates again following the glaze manufacturer's guidelines.
Allow glazed, fired plates to fully cool before removing them from the kiln. Further embellish by applying glaze-resistant waxes and additional layers of glaze, or by painting designs on the surfaces. Ideas for designs include scrolls or floral patterns around the rim of the plate or a floral or geometrical pattern on the centre of the plate. Re-fire the homemade plates again and repeat the reglazing process as often as necessary to achieve the desired design.
After cooling, add additional clay embellishments, if desired. Consider gluing raised elements around the rim of the plates, such as glazed pieces of clay sculpted into decorative balls, or premade pressed or stamped decorative clay pieces.
Add finishing touches to homemade plates by trimming and highlighting various design elements with food-safe decorative paints. Consider adding gold or silver flourishes around the rim of the plates. Or paint delicate scrolls around the centre of the plates.
Allow homemade plates to dry completely and seal with a food-safe spray sealant, if desired.
Tips and warnings
- If homemade plates are to be used for decorative purposes only, add wall-hanging hardware to the backs of the plates so they can be displayed.
- Some pottery glazes have texturising elements that create a somewhat rough surface, which some people may find to be undesirable when used for serving food.
- Wash handmade decorated plates carefully after use. For best results, hand wash in warm, soapy water using a mild detergent and a non-abrasive cloth.

Arguments vs Parameters and The Rest Parameter
Joe Eames

Knowing the difference between arguments and parameters can be important.
But before we begin, just a quick note that our new course, Fundamentals of Angular, is out and completely free. That's right. 100% free. Nothing behind a paywall. This isn't a half course or anything. This is the whole enchilada. Go check it out.
And for a video version of this blog, click here.
I recently ran a quick little twitter poll to see if people, in general, knew the difference between parameters and arguments. The results of the poll were quite interesting.
Image for post
Image for post
Only 50% of people were confident with the difference between arguments and parameters, which makes this a good subject to review.
An argument is the value you pass into a function. A parameter is the name the function assigns to that value. That is the difference. Often times we use these two terms interchangeably, and most of the time the difference is unimportant. But it can matter, so learning the difference, and learning to use the appropriate term at the appropriate time can help with communication of all kinds.
Image for post
Image for post
In the above example, "itemName" and "quantity" are parameters, and "handSanitizer" and 300 are arguments.
This actually clues us in as to why the arguments object in JavaScript is named arguments, and not parameters. Arguments are the values, not the names. The arguments object contains the values, but doesn't care about the names.
If you're not familiar with the arguments object, it's a global object that gives you information about the arguments used in the function call for the current context.
So in this example:
Image for post
Image for post
Notice how the arguments object was never created or referenced, it just exists. Inside that function, those three calls will log out "2", "Hand Sanitizer" and "300" respectively.
Now, why is there an arguments object when we have the named parameters anyway?
Well, JavaScript is just so loosey-goosey that it doesn't care if you pass it more arguments than there are parameters.
Now, look at the sentence I just typed. This is a GREAT example of why we need to understand the difference between arguments and parameters. If you use those two terms interchangeably, then the sentence makes no sense. But they're not the same thing. And understanding them lets us learn about things like the arguments object.
So continuing on, you can pass more arguments than there are parameters. Let's look at a case for this. Let's say we want a function that can receive a list of numbers and add them all up, but doesn't require that they're in an array, and can instead be passed in as separate arguments. Doing this with separate arguments would be impossible, and even if we do our best it's messy.
Image for post
Image for post
But with the arguments object, this is trivial. Since the arguments object only has the arguments that were already passed in, it's basically an array of numbers we just add up.
Image for post
Image for post
Unfortunately, arguments is only an array-like object, and not a full array, so we can't do things like reduce().
But thank you EcmaScript for coming to the rescue here. The Rest Parameter is a way to get the best of both worlds.
A rest parameter is a special parameter in a function signature (good thing we know what a parameter is vs. an argument) that is signified by three dots before it. It must be the very last parameter in a function signature. This parameter receives all the arguments that don't have named parameters already, and is an array of those arguments.
So our new AddEverythingUp method would look like this:
Image for post
Image for post
You can mix in named parameters (only before the rest parameter).
Image for post
Image for post
So for most uses, a rest parameter is preferred over the arguments object, and many developers now consider the arguments object to be a code smell.
And that's the rest parameter, and also arguments and parameters. Think you get it? Try this challenge and see if you can solve it!
How to learn five times faster
Here at Thinkster, we use educational science to teach yo five times faster than just about anything else out there. How? With proper instruction based on educational principles and hands-on exercises, you will retain 75% to 90% of what you learn. Without these techniques, you only remember 7% to 15% of what you learn. That's why you can watch a video or a course or read a blog and feel like you need to watch a couple more before you really "get it".
You can see this in action in our courses. And you can get it for free in our Fundamentals of Angular course. Go check it out.
Happy Coding!

Gas Faucets Frequently Asked Questions
Jul. 12, 2021
Gas taps are the backbone of most laboratories and play a central role in daily operations. But even though they are so common in these environments, it is not common knowledge how they work, what they are specifically used for, and what gases they are suitable for.
Therefore, the laboratory valve supplier will answer all your gas tap questions in one helpful post.
What is a gas tap?
A laboratory gas tap or laboratory gas valve is a device that controls the flow of gas from its source of supply through a pipe.
They are essential devices in a range of chemical and physical exercises, from the basic level all the way up to commercial, industrial or research laboratories. They are usually located on a laboratory bench where they can be easily accessed by students, scientists or laboratory technicians.
Laboratory Gas Valve
How do gas taps work?
Gas faucets work very similar to faucets in that the valve blocks the free flow of gas until the faucet is turned and the valve is opened. Different faucets have different types of valves. An example of this is the push-turn valve or needle valve used in a drop lever faucet.
Gas Faucet Applications
Gas valves are used to control the flow of various gases in laboratory applications. The most common are natural gas and liquefied petroleum gas. Gas taps suitable for most pressurized gases in this environment are available.
Water Valve
Water Valve
Why are gas faucets yellow?
Gas tap controls are often bright yellow in school laboratory environments where they need to be easily visible and error free for safety reasons. The yellow pull-down lever, used for a series of gas faucets, allows teachers to quickly scan the room and determine if the faucet is turned on.

Definition of Shotgun sequencing
Shotgun sequencing: An approach used to decode a genome by shredding ("shotgunning") it into smaller fragments of DNA which can then be individually sequenced. The sequences of these fragments are then ordered, based on overlaps in the genetic code, and finally reassembled into the complete sequence.
The "whole genome shotgun" method is applied to the entire genome all at once, while the "hierarchical shotgun" method is applied to large, overlapping DNA fragments of known location in the genome.Source: MedTerms™ Medical Dictionary

Elbow carrying angle - excessive; Excessive carrying angle of the elbow; Cubitus valgus
When your arms are held out at the sides and your palms are facing forward, your forearm and hands should normally be about 5 to 15 degrees away from the body. This is the normal "carrying angle" of the elbow. This angle allows your forearms to clear the hips when swinging your arms, such as during walking. It is also important when carrying objects.
Certain fractures of the elbow can increase the carrying angle of elbow, causing the arms to stick out too much from the body. This is called an excessive carrying angle.
If the angle is decreased so that the arm points toward the body, it is called a "gunstock deformity."
Because the carrying angle varies from person to person, it is important to compare one elbow with the other when evaluating a problem with the carrying angle.

Chronicle of Foreign Lands
The Zhifang waiji (Chronicle of foreign lands) is a concise geography of the world, the first of its kind written in Chinese. The Italian Jesuit missionary Matteo Ricci produced a map of the world in Chinese in 1584. The map, which followed Western principles of cartography then unknown in China, underwent several revisions between 1584 and 1602. Ricci's fellow priests Diego de Pantoja and Sabatino de Ursis were instructed by imperial order to compose a book explaining the map. Pantoja died in 1618 and the work eventually was completed...

Hourglass funnel diagram PowerPoint and keynote template is a professional design that can be used to show multi-topic presentations. Normally hourglass and funnel represent the different spheres of organized knowledge. Hourglass indicating time management and the funnel symbolizes the filtering process; both have certain values in management and marketing areas. Historically hourglasses have been used to measure time years back. One can calculate the time by the amount of sand that has been distributed from the top part of the hourglass to the bottom. When all the sand is found at the bottom, it means that time has run out. Users can apply the hourglass theory to project reports and studies. This template can use to display the importance of time scheduling in project management and personal development.
Funnel diagram PowerPoint is used to show the conversion rate of a specific product. It is for sales presentations. To achieve preferred goals and milestones this diagram process flow chart surely helps you. The process behind marketing and sales and the strategies and plans and project and business development can be illustrated with this simple hourglass funnel diagram PowerPoint. The layout has seven segments including the heading section. Users can depict six-element or concepts related to the theme. Each segment is colored differently and having individual text areas. Any topic like; time cost, quality, HR management, risk evaluation, procurement can display on this structure. It is for the presentation of organized knowledge than random perception. The presenter should try to filter out the concepts through using the method of science and make an exact presentation before the executive audience. The presenter can resize the design and its objects, also customize the color including background. Users can search funnel diagram to showcase business and marketing plans.


SLC 500 Timers
Thread Starter
Justin Lund
Can anyone please help. I need to input a separate value into 16 timers but also need to increment or decrement all of them together at the same time.
I am using a Panelview 550 and an SLC5/04
Jocko Harmet
You could make all of your values an offset from a single value(Register X - then incrament that value -
Each value would go into a separate register with a number such as 16000 added to it(same number would start out in Register X). For examples sake, this would be registers 0 through 15
Then the timer value for timer 1 would be (Register 0 - Register x)
The timer value for timer 2 would be (Register 1 - Register x)
Then when you need to incrament or decrement, you would perform this function on Register x only.
The number 16000 was used assuming that your timer is cabable of a 16 bit preset
This number would need to be greater than the maximum timer value. This would allow you to decrament all the way down to 0.

Please make your query more clear. As such what do you want to acheive? Which value you want to increment or decrement? Preset Value or Accumulated value? Are you looking forward to synchronise the timers?
I don't understand. Are you wanting to load values into the timer preset addresses? Then do you wand to increment and/or decrement the preset values all together with a pushbutton, or something? If you know the relative values you want, the operator could enter one number, then let the plc do the math and write to the presets. Otherwise he'll have to fat-finger each one seperately. If you want to do a group inc/dec from the entered values, use indirect addressing to "catchall" the values with each adjustment.
Are you saying that the initial values will be different but thereafter you will add or subtract the same amount from all timers?
Not sure if I understand the problem, but:
On the panelview, use the timers PRE word as the tag for the register. For example for timer T4:1, set the tag for the panelview as T4:1.PRE
In the PLC, use the timer blocks normally. The write will occur during the housekeeping portion of the scan (actually the communication slice, but it all occurs between scans).
If you want all timers running at the same time, just put them all in parallel on a rung. It would make a big rung, but it would work. Give
them some default time for programming, but know that the time will be overwritten when the panelview comes online.
For example, enter the following rung. B3:1/1 is the enable bit. This is for 4 timers, but you can expand it as needed....
(note: in RSLogix, you can get to the text entry prompt by typing / with the rung selected)
xic b3:1/1 bst ton t4:1.01 100 0 nxb ton t4:2.01 100 0 nxb ton t4:3.01
100 0 nxb ton t4:4.01 100 0 bnd
This will give you 4 timers in parallel with an enable bit to start and stop them. 16 timers would just be more branches. For readability and
trouble shooting, you may want to break them into smaller rungs that all use the same enable bit.
Hope this helps!
--Joe Jansen
Yes. The timer presets will be keyed in for each of the 16 timers. The operator then needs to be able to increment or decrement all 16 at the same time even if the values are different. It is a lot quicker than having to enter 16 new values.
Thank you.
Crucius, Wesley
I didn't interpret Justin's question the way Joe did, so I'll offer a suggestion.
My interpretation is that you wanted to use a single panelview "button" (or pair of buttons) to increment and decrement either the accumulator or,
more likely, the preset timer element for 16 different timers "simultaneously". If I've understood your question correctly, here's what
you need:
- pick an intermediate integer register to be written to by the panelview with a desired increment/decrement value
- add a rung of logic in the processor to check this imtermediate register for a non-zero increment/decrement value and add this value to each of the desired timer elements
- reset the intermediate increment/decrement register value to zero when all timer elements have been updated, so that the process can be repeated
- you'll obviously want some limit test logic to avoid invalid timer element values (both in terms of what the PLC considers valid values and what you're process considers valid values)
John Paley--Graphic Pkg Corp
This example requires the timer addresses to be consecutive!!!
After the initial preset values are entered, use indirect addressing to easily change the rest.
If you use a pb to increment the value, one shot it to latch a bit--b3/0. if b3/0 is true, add 1 (or whatever) to t4:[n7;0].pre dest t4;[n7;0].pre.
branch output--add 1 to n7;0 dest n7;0. this increments the index to 1. the next scan, 1 gets added to t4;1, next scan t4;2 etc.
next branch output if n7;0 > 15, move 0 to n7;0 and branch unlatch b3/0. this shuts off the routine and resets n7;0 to start over next time.
this method takes 16 scans to get all the presets incremented, but how long is a scan, anyhow.
Another way is to let the operator set the value of the inc/dec then add that number to the presets.
This example uses timers 0-15, but it depends on the number you reset n7;0 to to start and the number you examine n7;0 greater than to finish. It will work with any range of consecutive timers (or any consecutive data table values).
Look out--be careful not to allow the operator to enter a preset less than zero. The processor won't like it and will lock up when the timer rung goes true. You could do a similar indexed rung to check the presets before you allow a decrement in value that might put one less than zero.
I could e-mail sample [email protected]
Draw a data entry screen on the PV550 to display the actual values for the 16 timer registers. Link these to the addresses you are using. This will allow individual timer preset values to be set independently.
Next add an Inc/Dec object to the screen and use this to ADD/SUBTRACT to/from ALL of the timer registers simultaneously (via ladder in PLC).
I've used similar screens for recipe/sequence modifications.


Adjaruli Khachapuri - Gastro Obscura
Prepared Foods
Adjaruli Khachapuri
Economists use this cheesy bread as a metric for cost of living between Georgian cities.
Georgians make khachapuri (pronounced "hatch-ah-POO-ree") all across the country. This cheese bread is so popular that economists at Tbilisi State University actually use the dish as a metric for inflation and cost of living between cities. They divide the average household income by the "Kh-index" (the cost of ingredients, as well as energy like gas or electricity, needed to produce one Imeretian-style khachapuri in a given city). This reveals how many servings the average family can afford to make in each city.
Despite the ubiquity of khachapuri, the details of this dish vary by region. It can be double-crusted, round, square, cheese-topped, or cheese-filled. Georgians incorporate a wide array of cheeses and doughs, and will cook it on a stovetop or in the oven. Some versions contain bitter greens or boiled potatoes, while others are filled with whole eggs.
Adjaruli khachapuri, hailing from the Adjara region on the coast of the Black Sea, has three distinct features: an open-faced boat shape, a raw egg, and a pat of butter on top. Adjarians fill their bread boats with sulguni, a brined cow cheese that's a little bit sour and salty, with the elasticity of mozzarella. Even better, the Kh-index indicates that Adjara is on the up and up. More boat-shaped cheese breads all around!
Need to Know
To properly eat Adjaruli khachapuri, mix the yolk and butter into the melted cheese, then rip off chunks of the bread boat to scoop up the insides. Think of it as an all-in-one fondue.

Called the Cloud Seeding Pavilion, the 2,500-square-foot (232 square meter) structure is located outside the Design Museum Holon – Israel's only museum dedicated to design, which occupies a building designed by Ron Arad that opened in 2010.
Though it is used to hold small events, the pavilion is designed to be an attraction in its own right due to its ever-shifting ceiling plane made of thousands of white plastic balls.
The lightweight spheres move in response to even small changes in wind direction, creating an interplay of light and shadows on the ceiling and the ground.
"Our practice is always trying to work on the border of architecture and the environment," Rachely Rotem, director at MODU, told Dezeen. "When we first came to the site we noticed that it was very hot, but the wind was very present there."
MODU used a conventional greenhouse frame – very common in Israeli agriculture – which is inexpensive and easy to construct. Simple beach chairs under the ceiling encourage visitors to lounge and observe the movement above.
"The nature of good public space is that it's not over prescribed," said Phu Hoang, principal at MODU. "The project is less about the form than how you engage the public."
The 30,000 balls are made of recycled PET plastic and are suspended between architectural fabric mesh panels that allow air to flow through.
MODU conceived the structure as a prototype and the firm is currently in talks with another organisation about creating a second version on a different site in Holon.
Pavilions, Rotem said, have always been an important typology for architectural experimentation and research. Other recent pavilions include the water-purifying Cosmo by Andrés Jacque at MoMA PS 1 and a canopy of folded metal plates by Boston studio Höweler + Yoon in Pheonix.

Acid treatment of crystalline silicates is a facile method of creating pores for the preparation of crystalline silica-based microporous materials, but its success depends on the acid treatment conditions and both the composition and crystallinity of the starting silicates. Here, europium silicate Eu-AV-9 containing Na+, K+, and Eu3+ ions was treated with acetic acid for 1 d or 14 d to synthesize microporous silicate with high Eu loading by the selective leaching of K+ and Na+ from the silicate. The acid-treated Eu-AV-9 had both crystallinity and microporosity capable of adsorbing CO2, while the adsorption of Ar was very low. In addition, the values of both micropore volume and BET area of acid-treated samples increased when the time of acid treatment was increased. This result was attributed to the formation of structural defects caused by eliminating Eu in Eu-AV-9 over time of acid treatment.

I need a way to tag photos in a Delphi desktop application the way Facebook does it.
That includes some way to easily add the tags over the people, and then hovering the mouse over the person in the photo to show the tag.
The two suggestions in the answer given to: "Delphi Components for Face Identification and Tagging" don't solve this.
But I have no idea where to start, and have been unable to find ideas on the web on how to do this. How does Facebook do it? Or maybe there's a component for Delphi that will allow it.
What would be the best way to try to implement Facebook-like tagging?
p.s. This is some of Facebook's API definition for this: _URL_
Here is a Java program that implements the face tagging functionality that I want to do in my Delphi app: fb-photo-uploader

The key parameters of the API you cited are the picture ID, the coordinates, and the tag. The tag can be either the user ID of a Facebook user, or it can be free-form text (for the case when the tagged subject is not a Facebook user). Facebook uses just one coordinate because it uses fixed-size regions to denote a tagged area; the idea is that you click on the center of a person's face, and Facebook just stores that point.
If you display a picture in a TImage control (that's the obvious first choice, after all), you can detect mouse clicks with the OnMouseDown and OnMouseUp events. (The OnClick event is simpler, but doesn't tell you the coordinates.) Once you've acquired a point, prompt for a label to accompany that point. You can use predetermined labels, like Facebook's user IDs, or just use ordinary text, or use something of your own devising. The question of what you use to represent a tag value is orthogonal to whatever other questions you've asked so far.
The other half of Facebook's photo tagging is that moving the mouse over the image displays the tag text over the image, and moving the mouse over the labels below highlight the associated regions. Handle OnMouseMove events and write some code to display or hide labels and shapes as appropriate. If you use TLabel and TShape, you might not even have to modify the image, but showing those controls on top of the image might interfere with further OnMouseMove events for the image. It shouldn't take too long to try some experiments and see what works for you.

lkessler, I just read your reply to Marshall Fryman, so may have a couple options for you:
THotSpotImage - If you already have TMS components...
ImageEn - in case you already have them...
See w2m's answer #3 i think in further i need get all inner pixels of my selections, so how i can save my selections/objects?
Save selection just saves the selection itself. It does not save the image inside of the selection:
procedure SaveSelectionToFile(const FileName:string); SaveSelectionToFile saves the current selection to the specified file. Example ImageEnView1.Select(10,10,100,100); ImageEnView1.SaveSelectionToFile('selection1');.. sel1.Position:=0; ImageEnView1.LoadSelectionFromFile('selection1'); // this is like Select(10,10,100,100)
share|improve this answer
Good selection of options. I wish there was a THotSpotImage outside of TMS. I wouldn't want to get it just for that one component. I already use LMD ElPack for my additional components, and that's enough. – lkessler Apr 15 '09 at 0:08

I'm a bit confused as to your question. Are you trying to interact with Facebook or just copy the functionality?
If you are trying to copy the functionality: You should be able to just display the image, let the user select the rectangle, possibly copy the image to a new copy to notify the other person with, and apply a tag in a DB. Some helpful links: here is a select image example and here is the copy image portion example. I'd actually think you could do the select image in a paintbox but haven't actually played with one of those in forever.
If you are trying to access the API: The.NET interface may work for you. From what I can tell, there is no COM interface so you'd have to write your own connector or use a.NET Delphi app. Note: all of this information is coming from Google so I won't swear up and down that it's really the current state of things. The only other Facebook API request I saw was from 2007.
If you want to do automatic face recognition, OpenCV from the referenced question looks like a decent way to do it (especially if you have access to C++ Builder).

Thanks for the thoughtful answer and the useful examples which is the sort of thing I'm looking for.

In the Graphic32-library, you can have several layers upon each other in a image. One of the layers that is provided out of the box, is a TRubberbandLayer that allows the user to reposition/resize the layer at runtime.
The mousemove event for the TImage32-component, has a parameter that gives the layer currently under the cursor.
type TImgMouseMoveEvent = procedure(Sender: TObject; Shift: TShiftState; X, Y: Integer; Layer: TCustomLayer) of object;
A combination of rubberbandlayers and the mousemove-event should be good solution, I think.

The Importance of Festive Attire in the Healthcare Industry
In the healthcare industry, professionals work tirelessly to provide care and support to those in need. Especially during the holiday season, when many patients may be feeling lonely or unwell, it becomes even more crucial to spread joy and cheer. One creative way to do so is by wearing Christmas-themed scrubs. These festive outfits not only bring a smile to patients' faces but also boost the morale of healthcare workers. We're committed to providing an enriching learning experience. That's why we suggest this external website with extra and relevant information about the subject. christmas scrub tops _URL_ investigate and broaden your understanding!
The Psychology Behind Festive Attire
Research has shown that clothing choices can significantly impact our mood and mindset. When healthcare professionals don Christmas-themed scrubs, they are sending a positive message to both themselves and their patients. The bright colors, cheerful patterns, and symbols associated with the holiday season can create a joyful atmosphere, promoting a sense of happiness and optimism.
The festive attire also serves as a conversation starter, allowing patients to engage in lighthearted conversations with healthcare workers. This human connection can bring solace to individuals who may be spending the holiday season in a hospital or long-term care facility away from their loved ones. It helps to create a warm and empathetic environment that fosters healing and emotional well-being.
The Benefits of Christmas-Themed Scrubs for Healthcare Professionals
Wearing Christmas-themed scrubs can have numerous benefits for healthcare professionals themselves. Firstly, it breaks the monotony of wearing standard uniforms or lab coats, which can become mundane over time. By introducing festive attire, healthcare workers can add a touch of personalization and self-expression to their daily outfits.
Secondly, Christmas-themed scrubs can significantly boost team spirit and camaraderie among healthcare professionals. When coworkers dress up in festive outfits together, it creates a sense of unity and shared enthusiasm. This, in turn, leads to increased collaboration and a more positive work environment.
Furthermore, wearing Christmas-themed scrubs allows healthcare workers to showcase their creativity and sense of fun. In an inherently challenging and sometimes emotionally draining field, it's important for professionals to find moments of joy and laughter. The colorful and whimsical scrubs offer healthcare workers an opportunity to inject a sense of lightness into their workdays, ultimately benefiting their mental well-being.
The Impact on Patient Experience
Patients often associate hospitals and medical facilities with negative experiences, anxiety, and fear. By introducing Christmas-themed scrubs, healthcare professionals can transform this perception and create a more positive environment. Patients, especially children, are likely to be more at ease and receptive to treatment when surrounded by cheerful and comforting surroundings.
Additionally, the sight of healthcare workers donning festive attire can help patients feel more connected and understood. It reminds them that the healthcare professionals caring for them are not just professionals but also individuals who share in the joys and traditions of the holiday season.
Implementing the Tradition
Introducing Christmas-themed scrubs into healthcare settings can be done in various ways. Healthcare organizations can provide healthcare workers with a set of festive scrubs to wear during the holiday season or allow healthcare professionals to personalize their own scrubs with holiday-themed accessories such as pins, patches, or hair accessories.
It is essential, however, to ensure that the festive attire does not compromise the professionalism and hygiene standards of the healthcare industry. The scrubs should still be comfortable, practical, and adhere to any dress code policies in place. For a deeper understanding of the subject, we recommend this external resource packed with more details and insights. christmas scrub tops australia, discover new aspects of the subject discussed.
The holiday season is a time of joy, love, and giving. By incorporating Christmas-themed scrubs into healthcare settings, we can spread holiday cheer to patients, boost the morale of healthcare professionals, and create a more positive and festive environment. These simple yet impactful gestures remind us of the importance of compassion and empathy in the healthcare industry, ultimately improving the patient experience and overall well-being for all involved.
