• create a spectrum of the order from scratch (i.e. get a fft-based on the position of the same time deductions in the sample data)

  Hello people,

  THAT THE QUESTION PERTAINS TO:

  I play on 2 parameters of a system based on the sampling time: Rotary position and vibration (accelerometer g increments).  I want to take a fft based on the post to create a spectrum of the amplitude-phase speed order in / s.  To do this, perform the following:

  1 integrate (and scale) g vibration signal in the / s (SVT Integration.vi)

  2 signal sampled vibration resample the same time at an angle similarly charged signal (ma-resample unevenly sampled input (linear interpolation) .vi)

  THE QUESTION:

  Order in which operations should be carried out, integrate then resample or vice versa?  I didn't order would be important, but using the same set of data, the results are radically different.

  OR ORDER ANALYSIS 2.0 TOOLSET:

  I have the NO order Analysis Toolset 2.0, but I could not find a way to get the speed profile generation live to work with signals of position encoder DAQmx (via pxi-6602) quadrature.  In addition, it seems that I have to specify all the commands I'm interested to watch, which I don't really know at this point (I want to see all available commands) so I decided to do my own fft based on the post to get a spectrum of the order.

  Any help is greatly appreciated.

  The order is to integrate the time domain of first - creating a speed channel.  You now have a new channel of data.  In general I would put this in the same table of waveform with waves of acceleration time.

  Then re - sample your acceleration and/or your speed signals, and then you can calculate the spectrum of the order.

• exclude data based on the position

  Hi all
  
  I use oracle 10g.
  
  We have a requirement where I need to exclude the data based on the 1st character of a column value.
  
  A table has a column that contains the varchar value.
  The condition is to exclude all rows where the column begins with an alphabet.
  
  Example;

   customer table:
  cust_id    cust_name   cust_age
  A123          JOHN            28
  1234         NASH            43
  B345         DEAN            32
  4325         SHAUN          21

  Now I want to select only rows with cust_id = 1234 and 4325 as these 2 is not first character as alphabet.
  There are thousands of row in the table.
  
  One way is to write all the alphabets as:

    SELECT *
      FROM CUSTOMERS
     WHERE SUBSTR(CUST_ID,1,1) NOT IN ('A','B','C','D',..............'Z');

  But I'm sure there is a better way to do maybe a function that can list all the alphabet or something.
  
  Kindly tell me how to get this result.
  
  Kind regards
  Shane

  SELECT *
  FROM CUSTOMERS
  WHERE NOT regexp_like(cust_id, '^[A-Z]');

• Selection of DAQ PCI cards - pulse based on the position of the AO

  I build a replacement computer for an aging instrument control system, and I'm trying spec a PCI card to use.  My line of sight is on the M6229, but I'm a little confused as to if she's going to do what I want.  We will use LabView 8.6 for the software, and RT module is not an option.

  The question has been posted here in various forms, but I think that this iteration could be a little original:

  The requirements of the program are:

  -Two analog outputs are used to generate a raster 2D model, while the internal counter counts the pulses of preamp at each stage of the grid.

  -The dwell for each point must be controllable by the user (ideally as low as 0.01 ms), and the count rate can go up to 5Mcps.

  -The number of points x / y in the raster model is controllable by the user, a will have a maximum of 400 x 400 (160000).

  At the moment I'm simulating a 6229 in MAX and written a model of Sawtooth on channel X and a linear ramp on the channel of Y.  The sampling frequency / can be deducted immediately requested size of dwell and pixel of the user.  I generate the set of values of xy 2D matrix and write to data acquisition.  I use voluntarily no more points that are necessary, because this application prefers one out an alias on the AO conducted, channels to maintain a separate position for each pixel in the detector.  Thus, for example, for a 100 x 100 pixel image with 1ms live per pixel, the quick scan signal is essentially a 100 Hz sawtooth, sampled 100 times at a sampling rate of 10 kHz.

  However, the frequency of sampling for the pulse counter must be very high to follow with the input of the preamplifier signal.  I think that I can't have separate sampling frequencies for two separate tasks, so I'm left with a choice between creating an XY array unnecessarily large to match the sample for the pulse counter clock, or ask your question here

  Does anyone have any advice? In the end, I want to make sure we buy the best equipment for the job, but as always, we are also interested in the best bang for the buck.  Is a map of the M series not up to this task?

  Hi, Ram,

  You can use SUBSTR to get the antepenultimate character (in other words, the 3rd from the end: I don't get to use that Word every day) and the last 2 characters.
  If the 2nd argument SUBSTR is a negative number, this means the end count.
  For example:

  SELECT  city_state
  ,       CASE
             WHEN  SUBSTR (city_state, -3, 1) = ' '
             THEN  SUBSTR (city_state, -2)
             ELSE  'Unknown'

• Sorting of images based on their position on the page

  How would I go about sorting the images based on their position on the page? I've read a few articles which mention the use of table method fate and checking their x and y values to sort the table. While that works on the page elements that are perfectly aligned with their x and is the axis, it fails on a layout like this. Does anyone have any ideas on how I could create an individual table for line1, line2, Row3 etc based on his position there and then sort them based on their position X and then create the master table combining them in order?

  I'm new to javascript, so it's a bit out of my League. Any help will be much appreciated.

  

  Hi again,

  I found an idea that seems promising to deal with the issues mentioned above. The main problem, as you have no doubt noticed, is that we cannot simply count about to coordinates (x, y) 'as they are', even after having rounded values, to extract implied rows and columns.

  When we look at the layout below:

  

  our eyes instantly detect what he expected to be 3 columns and 5 rows, but this underlying order is not immediately accessible from all sort all of the coordinates. We need to improve the algorithm.

  What I propose is to speculate about the gaps that occur on the ordered sequence of coordinates x and y, respectively. To reveal these gaps, we will first sort the data along the x-axis:

  

  The figure above shows that the width of the rectangles. Each arrow represents a rectangle, and I ordered the elements by increasing x-centers. We can estimate that the element identified #1 belongs to a new group of this simple fact: its left coordinate (red mark) is higher than the coordinated right (blue guide) of the #0element. This observation will give us a strategy to identify gaps in the column.

  Then, the same method is applied to detect the lines. (Sort by values y, identify gaps, based on the progress of the min - max).

  At the end of this process, each object has a (column, row) coordinate pair instead of fragmented values (x, y) . So, we can calculate the final order, i.e. the weight of the comparison function.

  Here is my implementation of this algorithm:

  // ========================================================

  Hi all
  
  I have a requirement in rdf as follows:
  
  I have two or three lines of the SELECT statement. An amount column having both negative and and postivie values.
  
  Based on the value of the parameter I need to take these records.
  
  Say, if the value of the parameter = "Credit amount", then I have to choose the records, the amount column value is negative.
  
  If the value of the parameter = "Debit amounts" then I have to choose the records, which the column value is positive.
  
  If the parameter Value = "All", then I must take all records, including both positive and negative.
  
  Please suggest how to achieve this scenario.
  
  Thank you

• Change the text displayed, based on the threshold value

  Hi users of Labview,.

  I need help with display and editing text in labview.

  The text should display and change according to the following conditions:

  0 volt - "no power".

  1 volt - "controller ON".

  2 Volt - "Rotor Running"

  3 volt - "Rotor stopped".

  Based on the voltage read by the channel, the text must be displayed and modified on the same area of the front panel. For example, initially it will be 0 Volt and the text "No power" should appear as an indicator of text (and not as a warning message). He needs to change ' controller we ' when the chages of voltage from 0 to 1 volt. The canal reads the analog input voltage (range 0 - 5V).

  I'm relatively new to labview. So please give me pointers or from suggestions on how can be done. Any help is greatly appreciated.

  Thank you

  Hello

  Thanks for the crossrulz of notes, have not used the front threshold.  For this simple example, it is "symmetrical", but I can see how the values in the table have been does not correspond to the index position that is so true useful.  Learn something every day, I could not resist, wanted to try.

  OK, here's a sample VI that puts a custom message based on the crossing of a threshold.  Home work is to study the components before asking to :-)

  The dice are the analog signal of 0 to 6.   He rounded to the whole number to provide the index number.  Power is the index number in the index table, the table being hard-coded text messages.

  Two additional indicators may be deleted, useful to see what is happening.

  And get rid of the value 0 if you want the text to match the number, he he he

  Enjoy.

  

• How to I raise an event based on the State of a button?

  I'm trying to trigger an event based on the State ON / OFF button.  When I click on the button, I want the structure of the event in a loop to trigger each iteration until the button goes back to the OFF position, manually or programmatically.  Is there an easy way to do this?

  Thank you very much.

  A structure of the event is absolutely necessary?  It's so simple with just a case structure, as shown in figure 1.  If you use a structure of the event, you can place the structure dealing with the push button inside the time-out event, as shown in Figure 2.

  

• How better to insert a subarray (line) in a 2D array to the correct index which is based on the value of the first column

  Hello

  I would like to insert a subarray (line) in a 2D to the correct index table. The position is to say the index value depends on the value of the first column of the table 2d.

  As an examlple my 2d array would look like this

  230 50 215 255

  300 60 270 330

  360 20 350 370

  And I would like to insert another line (subarray) with the following values

  320 40 300 340

  This new line should be placed between the second and third rows (this is based on the first column only).

  I tried the threshold 1 d function table by taking an 1Dsub array of my 2d array (first column), then using the first of the new line (320) as the threshold. It sort of work, but it does not work when I start the table (IE there is only 1 row) and it seems to not work properly on other occasions (as explained in the help of Labview).

  Hopefully the explanation is clear enough for any suggestion. Thanks in advance for the help!

  Ahh, so try this.

  This will also work with an empty array.

  You want to do with this function it is a Subvi.

  Make the entries 'table' and 'subarray"on the connector, then 'new array' output.

  You can then put this Subvi in a loop with a registry to shift and it will help to add new lines in a sorted order, when they are added.

  That is what you were aiming for?

• Change the structure of program based on the input file

  I have a program that takes parameters of an input file and then executes a Visual acquisition, using IMAQ, controlling some other hardware at the same time.  The duration of the various stages of this process control settings.

  There is a sequence stacked structure to control the playback of the input file, the initialization of the hardware, and then a while loop on the last image to actual purchase.

  The user of the program now wish to have several games acquisition in the same race, possibly with different time settings.  This would mean different iterations of the final loop, based on the parameters of the input file.  There could be 5 games of acquisition on occasion, 3 on another, etc., in a performance of the program.

  The structure VI already seems a little baroque, and I don't want to make it even more complicated.

  I would appreciate advice on how best to proceed, because I'm really a novice of LabView.

  If you use a "State Machine" architecture, you can do exactly that.

  Instead of having a structure of stacked sequence, it is essentially a case structure in a while loop.

  Each case represents a State.

  So in your case, you would have a State for:

  -reading the input file

  -initialization of hardware

  -data acquisition

  You can have the user controls the number of iterations of the State for the acquisition of data that you want to run.
