• How to perform the subtraction

  I created a mileage reimbursement form using Adobe 10 standard (Adobe X Standard).  The form has an engine Total Miles field, another field for Miles of the home port and a field that must be the difference between these two.  I do not see a calculation for the subtraction function, so my question is double.  One, how can I get the domain to perform the mathematical function and two, how do I know the field is no to enter negative numbers?  I imagine it'll be a custom script that will be loaded into the properties of the field on the tab calculation, under the area of calculation script, but I don't know what would be this script.  Any help would be appreciated.  Thanks to everyone for their help.

  

  You can use this code as the custom calcluation code of the difference field:

  var totalMiles = + this.getField ("Total Miles Driven") .value;

  var homeMiles = + this.getField ("Home Base Miles") .value;

  var totalMiles = diff - homeMiles.

  If (diff<0) diff="">

  Event.Value = diff;

• OBIEE: Cannot do the subtraction between two columns

  I would like to see the difference between the expenses of the customer in the current from the previous period. Thus, each row contains data from a single client. And my first field (column A) lists the customer spending in the current field of the era and the second (column B) for the previous period. I tried to calculate the difference in my third field (column C).
  
  However, given that some of the cells in column A are "null", the respective cells in column C appeared also as "null".
  I tried to convert the column A 0 help ifnull null cells. But the respective cells in column C may not always do the subtraction.
  
  Help, please! Thanks in advance.

  Hello

  In the column C set Ifnull(Col A) - Ifnull(Col B) try this. I tried and it works for me.

• Align the two signals and measure the Phase Shift

  Hello

  I do an experiment in which I use the NI USB-6221 DAQ card. The jury is able to make 250 k samples/second. I want to measure two voltages in a circuit and find the phase shift between them at frequencies between 1 and 10000. First I ouputted a wave sinusoidal frequency variable through the Commission and applied to a test circuit. Then I used the Board to measure the two tensions consecutively (thus reducing the maximum sampling frequency at 125 k). I used the signals align VI and measured the two phases and then calculates the phase shift (VI attached in Phase 1). It worked well for the test circuit I built in which the phase shift went way logarithmique.20 degrees ~84.5 degrees and then stabilized. At frequencies above 5 000 Hz phase shift must have remained constant, but it varies more or less 1 degree. When the phase shift is 84.5 degrees, present a degree of variability is not particularly explicit. When I asked my program on the circuit that I really wanted to measure, the phase shift went from-. 5 degrees up to about 1.2 degrees. The change in the values of phase shift at high frequencies (> 3000) was environ.2 degrees. Given the small phase shift, this variation is unacceptable. Now I tried to use a sequence to each blood individually (increase the maximum sampling frequency to 250 k) and then align the two signals and measure the phase of each shift. When I use align it and re - sample Express VI to realign the two signals, I get the message "error 20333 analysis: cannot align two waveforms with dt even if their samples are not clocked in phase." Is it possible to align two signals I describe here? I enclose the new VI as Phase 2

  Matthew,

  I think I have an idea for at least part of the problem.

  I took your program data and deleted stuff DAQ.  I have converted the Signal on the chart control and looked then what was going on with the signal analysis.

  The output of the Waveforms.vi line has two waveforms, like the entry.  However, arrays of Y in the two waveforms are empty!  It does not generate an error. After some head scratching, reading the help files and try things out, that's what I think is happening: the time t0 two input signals are 1,031 seconds apart. Since the wavefoms contains 1,000 seconds of data, there is no overlap and may not align them.

  I changed the t0 on two waveforms are the same, and it lines up.  The number of items in the tables is reduced by one. Then I increased the t0 of 0.1 seconds on the first element. The output had both greater than the entry by dt t0 t0 and the size of the arrays was 224998.  Reversing the t0 two elements shifts the phase in the opposite direction.

  What that tells me, is that you can not reliably align two waveforms which do not overlap.

  I suggest that you go to 2-channel data acquisition and that it accept the reduced sample rate.  You won't get the resolution you want, but you should be able to tell if something important happens.

  You may be able to improve the equivalent resolution by taking multiple steps with a slight phase shift. This is similar to the way that old oscilloscopes of sampling (analog) worked. Take a series of measures with the signal you are currently using.  The make enough average to minimize changes due to noise. Then pass the phase of the signal of excitement to an amount that is smaller than the resolution of phase of sampling rate and repeat the measurements.  Recall that I calculated that for a 5 kHz signal sampled at 125kHz, you get a sample every 14.4 degrees. If shift you the phase of 1 degree (to the point/mathematical simulation), you get a different set of samples for excitement.  They are always separated by 14.4 degrees.  Take another series of measures. Transfer phase another degree and repeat.  As long as your sampling clocks are stable enough so that frequency does not drift significantly (and it shouldn't with your equipment), you should be able to get near resolution of what you need.  The trade-off is that you need to perform more measurements and may need to keep track of the phase shifts between the various measures.

• Time scale does not properly after separation of the two signals of virtual channel

  Hi all

  I have a problem when I use a virtual channel with two analog inputs. I'm cutting the two signals into two separate tables of waveform, as shown in the attachment. The two signals seem to be reading very well, the problem is that the time scale (x-axis) begins to act on the strange. Seconds displayed time seems to keep jumping up and down at a high frequency, resulting in the two signals of displayed does not correctly in the table of waveform. Could someone please try to help me? Any help would be greatly appreciated!

  Thanks in advance.

  Try to acquire a signal with first time information. You can replace the DBL 2D with a data type of 1 d wave. You don't need this code extra silly - just a function of Board Index to get the separate channels.

  You have your clock set to continuous samples. I don't know if you can use 'Wait until what' If you the task will never happen. Set your click on over and see what happens.

• How the process in two steps of authentication does not work if you are not in an area of cellular service

  Outside cellular service areas, IS those who know how the two step aunthicatuon process works in an iPhone 6, using the operating system iOS 9.3.4?  Would a being completely locked out of their iphone and apple services until they could find themselves in a cell service area? Or can it be accessed by a public wifi? Who beg to differ on whether or not it is beneficial to use when you travel?

  I did a little research to see if all Apple items shed light...

  See "How it works" in the Apple ID - Apple Support for two-factor authentication - a time that a device is approved, he'll never ask again unless you perform one or more of several things to "break the connection.

  If I were you, I would spend it TURNED off if you fear that one of these things could happen while you might not be able to obtain the code by SMS

  Frequently asked questions about the audit in two steps for Apple ID - Apple Support

  I'm confused as to why Apple would use two different expressions for what seems to be the same:

  • "Two -authentication"- and
  • "Two -step".

  The above two articles begin with a statement like: [underlining is unique, "BOLD" is synonymous with]

  "Two-factor authentication is just an extra layer of security of your ID Apple aiming to sure you are the only person who can access to your account, even if someone knows your password."

  «The two-step verification is an additional security feature for your Apple which designed to prevent anyone to access or use your account, same ID is they know your password.»

  Maybe someone with more experience can shed some light on your question and MY confusion?

• Why the extreme to express signal is broken

  I have an Airport Extreme b, g, n, ac cable (ethernet) to my router Verizon Wireless. The router has been updated by Verizon end of last year and works very well. From there, I have an iMac with 802.11 b/g/n/ac cable into the extreme as well. I have a Windows pc in another room wired with ethernet to the extreme as well.

  At the back of my house, I have an Airport Express b/g/n I used to extend my Airport Extreme signal for the past 18 months without any problem. I had problems of signal with the Express and it seems to re-defining the Express worked, but the image of my signal has changed my Airport utility on my iMac. Previously, the signal was solid from the far down to the Express, and the image on my iPhone 6, at the launch of my Airport utility has been broken from the extreme to the Express.

  Now the images are reversed where my iPhone has the solid signal, and my iMac broke the line signal. Someone knows why? It works, but the lines threw me.

  A dotted line between the terminal of the AirPort Express and AirPort Extreme indicates that the Express connects to the extreme by using a wireless connection.

  What do you want?... or... the Express linking to the extreme by using a wired Ethernet cable connection?  If If this is the case, there should be a continuous line between the Express and Extreme.

  What device do you have used when you reset and reconfigured the Express... the iMac or the iPhone?

  Did you completely turn off the iPhone, has waited a minute or two and then he fed up and checked the AirPort utility again this way?

• The USB-6009 reading signals

  Hello

  I use 6009 USB to read the signals of the PMT and other equipment for experiments and I have a few questions:

  1. is it possible to read a signal with DAQ assist? I looked around forums and have not seen any relevant element.

  2. it is probably true, but I have not yet checked. Is it possible to read the two signals in the same loop (for example, AI0 & AI2 in awhile put in loop)?

  I would be grateful if you point me to the right direction.

  Thank you

  A

  P.S

  I should probably mention that I want to read the signals with using DAQ hardware help because of the assumption that the DAQ Assistant is slower than a direct measure.

  HEY Fan, Ravens

  Nevermind, I figured it out... Well the first step of it at least :-).

  Thank you once again,

• Add two signals different dt

  Hi, I try to achieve the function Sum (+) and Sub (-) with the participation of waveforms, I know the problem and the different dt when dt is the same the smooth executing operations but I want to achieve something like this Waveform sum Figure 1 as you can see if two signals with different frequencies are added between them the result looks like Figure 1 , but with the same dt different frequency is not calculated and the amount always show that the two signals have the same frequency. How can I realize the amount similar to that in Figure 1? Thank you all

  Hello Silversky,

  It seems you want to do something like that...

  But the figure referenced never mentions the signals with different dt! Simply to create waveforms with same dt in the first place...
