Decimate an array of meaningful size to 1 GB of data and apply the filter

Hey guys,.

So I used a high-precision laser Interferometer to collect data to frequencing 10 MHz, which will lead to a 1 GB of raw data files. I converted this position given to speed for parsing data. But I still have a file of 1 GB with billions of lines for treatment. I'm supposed to get all frequencies below 1500 Hz according to the results in the time domain analysis for lower frequencies. I have no idea on how to proceed on this. Any help is greatly appreciated.

In addition, due to the size of the high line, Labview meets to errors of memory, that's why I want to decimate the 1 GB file into meaningful data.

  • When I go to my pictures and zoom in on it and then click on print schrinks it down to size. I want to zoom and make the image more closely

    I want to zoom in on my pic. and printing and it keeps schrinking it to the low size ot.

    Hi wtfe.

    It is normal that you cannot print the entire image after zooming it.

    When you zoom the image and select to print automatically to change the zoom level print as normal image.

    However if you want to print pictures after that zoom you can only do this to some part of the image and import later than some larger version of the image in any photo editing software, save it as a separate image and then print it out.

    I hope this helps!

  • Dynamic PDF up to 200 images, the size of the pdf is greater, cannot save the data and images to the form

    Hi all

    My client would like to dynamic images up to 200 photos to my forms. It works very well. However, when I add images up to 35 images. I could not add images to shape more. Then I save data on the form. All the images and the data entered on the form are missing. I don't know why.

    If I add only 10 images - I can record data and images on the form. 15456 KB is the size of the pdf.  I was unable to add more photos or data on the form.

    There may be a problem the size of the pdf? How big can make a limited dynamic pdf?

    Can save us the information and images as much as we want?

    I spent two weeks to work and trying to figure out this problem. However, it is not successful.

    Help, please

    You must ensure that your users do not import large images.

    Therefore, you can use a script on the change event of an image field that checks the size of the data and warns the user if the file is too large.

    function formatNumber(number) {
        var num = number + '',
        x = num.split('.'),
        x1 = x[0],
        x2 = x.length > 1 ? '.' + x[1] : '',
        rgx = /(\d+)(\d{3})/;
        while (rgx.test(x1)) {
            x1 = x1.replace(rgx, '$1' + ',' + '$2');
        }
        return x1 + x2 + "KB";
    }
    
    var sizeLimit = 200, //allow upto 200KB images
      thisSize = Math.round((this.value.oneOfChild.value.length * 3 / 4) / 1024);
    
    if (sizeLimit > 0) {
      if (thisSize > sizeLimit) {
      xfa.host.messageBox("Note: With " + formatNumber(thisSize) + " the size of the imported image is greater that the recommended maximum of " + formatNumber(sizeLimit) + ".\nLarge images can cause a insufficent performance.\n\nIf possible, use images with the following recommended specs:\nFormat:\t\tPNG or JPG\nColor depth:\t8 Bit (higher is not supported)\nColor space:\tRGB (CMYK is not supported)\nFile Size:\t\t" + formatNumber(sizeLimit), "Recommended image size exceeded", 3, 0);

  • Adding items to an array of unknown size several times

    Hey,.

    I had an application that communicates with a device (a generator of microwave) via the Protocol modbus RS-232. It is within a state machine. The VI running generator initialization first and then move to the State 'pending', where I have a structure of the event to follow any value change of control. In the structure of the event, a timeout of 300 ms is implemented, because communication to the generator must be active at least every second (if not a defect is reported). In the case of timeout I read all record and display values.

    Within this time-out I would record a value of the indicator ('measure Pfwd') several times in a 1 d table (the table size is unknown!). However, I would like for the variable to record only when the indicator 'MW?' is 'TRUE '. And "MW?" goes from 'FALSE' to 'TRUE' every time, I would like to start writing on a table from the beginning.

    I tried several options, including the table to remodel, but I can't make it work. Or it works in a separate VI, but when I use it within the structure of the event and state machine, nothing works.

    If someone has an idea, it would be welcome...

    Thank you

  • Get the array of unknown size of the CVI code module

    I'm creating a type custom for my client, and I've encountered a problem that I'm not sure how to solve.

    Here's the situation:

    We have a custom step in which the main code is executed within a step after step. The code acquires samples of an instrument, but it is unclear how many samples will be returned. The CVI function has a table, the size of this table and an output parameter that indicates how many samples have been returned as parameters.

    void AcquireSamples (double* samples, int samplesBufferSize, int *numSamplesRetrieved)
    

    The goal is to have the array returned by the size of the number of samples taken.

    I tried several ways, none of which works completely. The problem is that, as described here, TestStand creates a temporary table to move to the code module. but it does not resize the TestStand array property. So I need to manually resize the properties of the table, and I did not understand an elegant way to do it.

    It would be easy if I had to create just a not, because I could use expressions after. I'm creating a type but I don't have that luxury (my code should allow the customer to enter expressions of post, but I run the risk of my client, removing any expression after default I get home).

    First question:

    I noticed when I was creating a stage with a CVI code module, that additional results allowed me to specify logging in both settings [in] and [out]. This I extrapolated that the parameter expression was evaluated before calling the function both again after the call to the function. I did some tests, and it doesn't seem to work that way.

    (1) this is expected behavior? I don't see it documented anywhere, if can I rely on it remains the same in future versions of TestStand?

    I used this behavior to my advantage to create an expression that does what I need an an step code module. But it does not work for a module of code to a later stage.

    I did a small test DLL file and sequence illustrates my problem. I tried to document the file in sequence to show where I'm stuck. You will need to put the DLL in one of your directories to search for the type of custom work.

    Any help would be greatly appreciated!

    I think the problem is that the C programming language does not provide enough information for a caller to know the size of an output table in any kind of standard. I recommend again, you pass a CAObjHandle which is the variable of array instead and set the table directly using CA_Array1DToSafeArray() to create a safearray and SetValVariant on the propertyobject which is the property of the table to set the table. Don't forget to free the array (using CA_SafeArrayDestroy()) that you created with CA_Array1DToSafeArray after that SetValVariant call to avoid leaks.

    Hope this helps,

  • What is READ the array returned by the DAQmx meter? How can I know the two functions DAQmx READ data stream in the same WHILE loop?

    I have a question about the order of execution.  In the WHILE loop, I have two things to measure, period and tension using the DAQmx READ functions for voltage and the meter.  In the end, I want to collect these data as points almost simultaneously as possible, as a pair and then send them together to another piece of code (not shown here) which them will result in some sort of command for an engine.  It would be run, and then I want to perceive the tension and the period at a time later and do the same thing.

    (1.) I'm a little confused on what the meter of the READ function is back because it's a table.  What is a picture of?  I thought that it was up to the value of the individual periods between rising edges.  The output of the counter 1 DBL d's a table. How many elements in this table, and what determines the size of this table?  Are the elements of the array the individual delays between the edges?  How many values are stored in the array by executing?   We take the AVERAGE of the last 15 items, but do not know if we are throwing some of the data or what.  How to understand the composition of this painting?  How can I change the composition of this painting?  Is it possible to measure only one period at a time, for example the time between TWO edges?

    2.) Will this WHILE loop execute as it gathers tension and a "period table ' (remains to be understood by me) by TIME running in a loop?  In particular, we want that the value of the tension associated with the value of the AVERAGE of the period "array", so we can use two data items to create orders of next control every time that the two values are reported.  The structure for the delivery of vi will be attached data in pairs like this?  I understand that one of the READING functions run not before the other function of READING in the WHILE loop.  I want that the period "means" and "strain (Volt) collected at the same pace. This vi will he?

    Thank you

    Hi David,

    I suggest including the DAQmx Start Task function. If it does not start before the loop, it starts the loop and work very well, but it is not as fast and efficient. In the model of task status, task wiill go to run the checked each iteration of the loop and then back the time checked running when it restarts.

    The status of the task model: http://zone.ni.com/reference/en-XX/help/370466V-01/mxcncpts/taskstatemodel/

  • Is it possible to increase the font size on web pages? I can increase the size of the page but then lose the ability to see the entire page.

    I've just updated El Capitan, but the font size on web pages went all teeny weeny.

    I was wondering if we could increase the font size? The page can expand via "zoom in", but then lose the ability to view the web page in the blink of an eye.

    Thanks in advance.

    Yes.  Open the Terminal app and type the following command followed by the Enter key or return:

    : write com.apple.Safari com.apple.Safari.ContentPageGroupIdentifier.WebKit2MinimumFontSize - int XX

    (triple click on the line to select it to copy and paste into the Terminal application).

    Change the XX to the font size you want as the minimum font by default.

    Or you can use a css style sheet.  This site describes it and the Terminal method: specify Minimum font size in Safari 10.0, macOS Sierra

    The photos full size will always go to the cloud. They also remain on (or download) your Mac depends on if 'Download this Mac originals' or 'Optimize Mac storage' is ticked in Photos > Preferences > iCloud. If it is enabled, it also depends on how much storage is available on your Mac.

  • I did the screen too small (using about: config) and lost the address bar and all the menus. How to restore the display on a screen size can be used?

    I changed the size of display screen using about: config, as stated in the other answers help. After you use a value of 1.0, such as recommended, I've experimented with other sizes, because it seems small. I have entered a large number by chance (a typing error) and made the display so small that only a bug could read. And I lost all the features: bar address, menus, home, Favorites, settings icons.

    I uninstalled and reinstalled Firefox, thinking that this would fix it. But the new facility displays the same way: unreadable and no functionality.

    I found instructions on resetting to the factory settings, but cannot perform this task because I have to be able to access the menus to do so.

  • Why the same photo's file size different in Photos and in the Finder?

    I have a photo size 4608 x 3456. When I open the file information in the Apple's Photos app, it says that the file is 7.8 MB. When I open the same photo in the Finder and look at the news file, it is said that it is 3.1 MB on the disk. Why does this happen? All other metadata is the same in the pictures, Finder, Lightroom or Photoshop, but I can't understand why the file size seems to have changed since I dragged photo pictures to the Finder.

  • Blind Presenter: apply the font size to all slides

    Hi all!

    Keynote is a great tool for blind people create presentations; It works very well with the Apple own screen reader, VoiceOver.

    I have a few questions for you guys. your answers will make my workflow much more effective.

    (1) I know, use the minimum font size is 30. How many characters will fit online?

    (2) I've copied the text in a text document in a slide; of course, the font and size are not the same. Can you assure me that all fonts and sizes remain the same throughout the presentation?

    (3.) I have a table of 5 x 5 with numbers on a slide. I was told by sbd. who could read but not edit the documents Keynote (with Open Office) as the table is readable, but could be many, many more great. Is there a way of self-centring a picture so that it fills the slide?

    any ideas would be very appreciated. Thanks & best regards, Markus

    I regularly create educational materials for students with visual impairments through audio recordings.

    I can't imagine the challenge for blind people, creating material with Keynote.     I hope that the following remarks are useful as a point of departure if nothing else.

    I know, use the minimum font size is 30.

    In fact, the font size must be determined by the final product, which the spectators and the environment where the presentation takes place. Text at the point indicated 30 in a conference room is far too small to be legible, 30 points may be appropriate when sitting in front of a screen of 2 feet farther.

    How many characters will fit online?

    This, once again, must be determined by the final product, and not the number of characters can be demonstrated. What is really important is the number of words on a slide, not the number ofcharacters.

    The number of words that are easy to read on a projection screen in a small training room will be different for the number of words that are easy to read in a web browser on a computer screen.

    The rule for text created by professional designers on television broadcast as well as projected communications is a maximum of five words per line and 6 lines per page, a maximum of 30 words per slide. For example, in Europe, there are legal requirements imposed on broadcasters for viewers to read text easily.

    I copied the text to a text document in a slide; of course, the font and size are not the same. Can you assure me that all fonts and sizes remain the same throughout the presentation?

    Use the dough and the Style of game in the edit, the keyboard is shift option order V

    the table is readable, but might be much, much more. Is there a way of self-centring a picture so that it fills the slide?

    Select the table, and then increases the font size of the required amount.

    I am happy to answer questions about my answer.
