• Trace the outline of the acquisition of the live camera: best strategy?

  Hello world

  I am creating a VI in order to acquire images from a camera (Basler scout). Among the features, I need to implement, one is the direct route to the contour of the gray scale values to increase their visibility (I then use it to tune in to a light source a Gaussian distribution centered).

  My problem here is that the images are too big and the whole VI accused, with a new track that appear every 3 to 5 seconds, which is too long. A constraint is that I must be able to record images with full resolution.

  Attached are 2 easy examples, one using labview only and the other using Matlab to decimate the number of pixels and a typical result. The two performed in the same way, too slowly.

  Ultimately, conversion and decimation in matlab seems very time consuming too. I'm not a labview expert so I can have overlooked an easier way of doing it, but so far I feel really stuck...

  So should what direction I follow? MATLAB or Labview? What could I use in Labview to reduce processing time?

  Hope you can help me,

• Use ContinousPDF.vi with NXT blocks

  Hi all

  I'm programming an alogrithm location, which uses the ContinousPDF.vi to trace the current location of the robot that follows a Gaussian distribution. The problem is that the VI that uses the ContinousPDF.vi is developed in order to make a NXT Robot. This VI uses NXT bloks. The combination of this block with the PDF it does not work.

  Is it possible to fix this?

  Thank you!

• 625 x noise specification

  I have a card PCI-6255 that I intend to use for certain sensitive measures. I'm trying to put together a budget-to-end error and I have a few questions. My model is in terms of number of analog-to-digital converter (also known as the LSB in your datasheet). In the table of absolute precision on page 5 of the 615 x standard OR I see a column called random noise, (uVrms). I think I understand the residual gain error, offset error residual and associated with it and the INL error, but random noise is confusing to me. Here's why: on the +/-2V of type range, the random noise is 16 uV.  On this beach, the resolution of the ADC is 6.1 uV so random noise is about 2.6LSB If I look at the +/-5V Beach, I see a random noise of 140uV.  On this beach, the resolution of the ADC is 305uV so random noise is well under a LSB. Therefore, in the budget of my mistake, I can use "1 LSB" for noise random when on the beach of 5V, but I have to use LSB '2.6' or '3' when the type 2V range. I expect a signal of about 150 mV riding on a 2, 5V CC.  I was worried, I might need to compensate the signal (remove the 2, 5V dc) in order to use the +/-gamme.2 volts to get the best resolution.  Also, I thought that I would get better sound performance too.  In looking at the figures here, but looks like I'd be better off using the +/-5V range (assuming that there is enough resolution) because the readings have less noise counties (even if it's more noise volts). I can explain the error of Gain and Offset error by injecting known signals and making a "correction of the software.  Not sure, but I think I can correct for the INL also if I use a 2nd or 3rd order polynomial.  It is the random noise, I have problems understanding. Here's the question: what is the random noise in table AI accuracy for 625 x boards?  Can you give an example of how NEITHER could have measured it? Secondly, note 2 says "sensitivity is the smallest voltage change this canbe found. It is a function of the noise. "He measured with a signal to noise ratio of '1' or '2' or some other standard, or is it a calculated value? Thank you MG

  The function of Gaussian Distribution is often used to describe the noise. Random noise spec'd in the table of precision is a gap type distribution of probability of noise and was probably calculated using statistical analysis. That's why the uncertainty of noise takes into account a 3 coverage factor that represents the largest part of the distribution.

  

  

  With respect, the specification of sensitivity, this requires a more detailed explanation, but it is essentially an industrial standard that takes into account more statistical analysis on a signal when awarded with noise. According to me, the mix is a compoenent of this measure.

• What is the best Linux distribution to work with Firefox (or Thunderbird)?

  With the advent of Win8 & Win10, I am considering (re) installation of Linux. I stopped using it because I was not getting timely Firefox and Thunderbird updates. I rely on Thunderbird calendar & Tbird interface.
  So what is the Linux distribution to be more likely to be kept up to date?

  Regular distributions Linux versions may be supported for a few years more or less Long term releases of the same or other Linux distributions support there.

  The drawback with the LTS (like Ubuntu with some versions) versions, is that they tend to use older packages more stable vs using the most current set.

  Older versions LTS which are always supported by distribution may not meet required minimums to use the current version of Firefox for example.

  https://www.Mozilla.org/en-us/Firefox/41.0/system-requirements/

  The current currency out June 30, 2025 is supported until April 2019, so there are options.

  openSUSE is a community which tries to keep some older versions updated when openSUSE drops in support.

  https://en.openSUSE.org/lifetime
  https://en.openSUSE.org/openSUSE:Evergreen

  Linux for Firefox 41.0 requirements are the same for Firefox 17.0. However, a big change in a while is GTK 3.4 or newer will be the new requirement, probably to start Firefox 43.0 communicated that he was going to be Fx 42.0 release.

  It looks like this bug. If you have a Bugzilla account, it would be useful to vote for this issue.

  It seems that lists with a description that includes several words have this problem. The bug report suggests to replace whites "" between the words in the descriptions of these lists with an underscore "_".

• Distribution-double processor MacPro 4,1 of RAM Board

  Hello world.

  I currently have a tray of uniprocessor MacPro 5.1 with 32 GB of RAM (4 x 8 GB) - 3.46 GHz six core (I replaced the 2.8 GHz processor it initially comes with).

  I recently bought a MacPro 4,1 dual processor tray with 32 GB of RAM (8 x 4 GB) - dual 2.26 GHz quadruple-heart, with whom I intend to replace the tray uniprocessor (after I have updated the firmware of 5.1 and swap on processors with two 3.46 GHz).

  I intend to move my original 32 GB of RAM to the new status bar and use of the 16 GB of RAM of the double set. Is there a better/correct set of distribution of RAM; 24 on a single series and 24 GB on the other (for example a 8 GB, slots slots two 4 GB, slot machines three 8 GB, slots four 4 GB), or is it possible to place the RAM everything?

  I just hope that the RAM on the Board of two processors are 1333 MHz DDR3 ECC, as what I currently have.

  Thanks in advance for any help!

• FIRST HP: Normal Distribution

  Hello

  I am trying to solve the following equation:

  X - N(50,15^2) find Pr (50 < X < 70)

  When I type the above in the calculator, the following occur:

  

  I don't understand why I get a 'erf' rather than a decimal answer.

  Can anyone help me please with the help of the function of standard normal distribution on HP Calculator first.

  Thank you

  Please, do not change the settings of your CASE, as described. Usually it makes more problems then helps until you understand how things work a bit more. Default settings are almost always going to be better for most users.

  Basically, the reason for this is because you are in the display CASE. Click home, try again and you will see it comes out a decimal number. Putting a decimal value at the end of one of your own in the CASE would ALSO return a decimal value lead (as you say the CASE "Please calculate using values digital apprixmated, since I gave you an approximate numeric value with a decimal"), as would hit the function SHIFT + ENTER to close the last calculation After obtaining this result.  None of those are the best solutions instead of changing the settings as shown.

  As to which is the (Railroad), which is in fact the way in which the normal distributions are calculated. See this link for a large Description: http://mathworld.wolfram.com/NormalDistributionFunction.html

  Cite this page: ' or or erf may be expressed in terms finished additions, subtractions, multiplications and extraction of roots, and must therefore be either computed numerically or otherwise by approximation.»

  Essentially, the CASE is you give the representation exact, symbolic of your normal distribution using a function that represents a certain operation. These types of 'special functions' are becoming more frequent in senior type math/engineering calculations.

  When it comes to exact/approximate, mathematicians refer to the idea that something is "a perfect representation of the concept of this thing" or just "a number which is quite close to her.  For example, + infinity is a concept that CASES can actually understand, but a normal calculator could not - he could not hold a number large enough to be "infinite". Yet in many cases, simply put it in a very large number in the calculation is "good enough" to represent the positive idea of infinity.

  Another good example of this is pi. Are pi cannot be represented as a decimal number is perfect, but in most cases a round off the coast of the value is "close enough".   The first CASE mode takes all integer with no decimal to be "the idea of this number. For example, sqrt (2) return sqrt (2) in the form of CASE. It is not a number that can simplify low. If you try to do SQRT(2.) (<-note the. after the two), you say really "take the square root of the number which is"close enough"of the ideal value of 2. The calculator then returns a number that is "close enough" to the result perfect, exact square root.

  If you get an accurate result and want to see the decimal approximation, just press SHIFT ENTER. This sign of equality gribouilli little is the mathematical symbol for "approximates of»

  As to the last question, use this rule to help go you as you - if you try to get an approximate result of decimal number, the home screen is where you work. If you want accurate results, symbolic algebra, the CASE screen is where you work. If you are in the display CASE and you want a decimal result, press shift ENTER to run the command "about" that will make an estimate time of your last result in a decimal number. Make sense?
