• full waveform graph to calculate the area under the curve over time

  Hello

  If please find my attached VI and help me please for integration to get area undercut for my chart of waveform.

  I would like to find my wave power wind energy production chart oever within one month of time.

  I think I have to integrate to get the area under the curve and so I m now using tool integrated into labview attached.

  As I did not wait years for my result and so I want to make sure that the tool that I m using is correct.

  Please advise me what method I will use for my chart.

  Dominique says:

  I would like to integrate my table of power over time (table of power is on each interval of a minute) and the entire graph is one month. So, I'll put dt = 1?

  You put dt at some units you want in the final result. If you want Wh, you want dt in hours. If the spacing is currently a minute, you can express in fractional hours and use the result as dt. Try dt = 1/60.

• Advice on the restructuring of code to avoid the downturn over time

  Hi, I am a new user of LabView, you want some advice on how to better structure the program I wrote and which is used to perform a hydrostatic test arrangement. Data are collected on a module of AI cDAQ 9207 and a cDAQ 9474 module is used to control the two valves that subsequently controls pressure in and out of the test Chamber. I enclose my first version of the reference code.

  What the VI is supposed to do when the user of the weapon system and strikes then the execution, the program switch will cause a transition of the test chamber through several States corresponding to the levels of different pressure for some time. Time curve vs pressure is written to a file of measures. I built using a state machine structure.

  My problem is, during the initial trial, when the duration of the test was about 5 minutes or so, the program went very well. However, once I started to test the length of the actual test of 2.5 hours, I noticed the program running slower and slower as time progressed to the point where it would take several seconds for each iteration of the loop, then by accident about an hour or two in the test. After scouring the articles and messages, I suspect the main culprit is the diagram of waveform and to a lesser extent DAQ assistant.

  While I need the loop structure data collection and case to run pretty quickly (preferably the order a few hundred s/s) I need the code to be able to react to changes in pressure in the room quickly enough, the actual data, that I need to store and display the graph can be as slow as a sample per second or even longer. My guess is at this point that I have to rebuild the program using some sort of architecture of producer/consumer, I'm looking for some advice on how best to structure the program.

  Data acquisition obviously belongs in the producer loop that will run at a fast enough pace and there will be a consumer loop that will run at a much slower pace for the Bulletin Board writing to the extent of the file vi, but where should I put the case of structure state machine which currently controls the valves? Should put in the loop of the producer since it must run at the same fast pace as the collection of data, so it can react to changes in pressure or should I build another loop of consumer for him? What other indicators (pressure and Boolean) and controls on the front panel, they should be on another loop operating at a medium speed I want to respond to a faster pace than the data to the chart/write the loop, but they do not need to be as fast as the data acquisition loop?

  Finally, I'm not quite sure what would be the best way to reduce the sampling rate of the data that I have in fact appear on the graph and the store in the file, it wouldn't make sense to create another task of measurement that samples at a rate below just for that purpose. Suggestions and advice would be greatly appreciated! Thanks in advance!

  My guess is that if you monitor the use of memory over time, you see that going up, Yes? Everything is is always a good idea to get rid of the express VIs, I would look for the problem of slowdown in the structure of the case. You repeatedly open and never close tasks which are created using some DIO channels. Hnece each time that the loop more memory is allocated. Try to move creating channel screws out of the loop, then the tasks are created once before the start of the loop and then written to as required inside the loop - and don't forget to delete tasks once the loop over.

  Mike...

  PS: You are right with your comments regarding the structure of the producer consumer. Basically it break up as things get quickly (DAQ IO) that there is in a loop, while the user interface and the stuff that can take a long time (such as the data record) are in another loop. You can even have three loops with one for the acquisition of input data and the other for the digital output.

  PPS: Finally don't forget that even if the structure of consumption of the producer is usually represented with everything in a single diagram, there no need to be. I wrote a lot where each loop is in his own VI which is run dynamically, then the application starts.

• create the voltage over time

  Is it possible to generate an output voltage on a DAQ 6009 A0? I have a data excel sheet that I put in a 2D array. The voltage is not constant over time. I have problems with the synchronization of the signal. I was able to trace the signal on a chart. This is the same as the original data to excel. I have two data streams. Voltage and time. But after separating the two signals how can I generate the graph?

  
  

• Check the configuration of time synchronization in ESX 4.1 for Windows domain

  Hello

  Sorry if this topic will cover many, but browsing the forums I found some conflicting info and thought that it easier to ask you if I had it correct.

  I'm ready to virtualize our Active Directory environment and put all our virtual machines RODCs.  We have an environment with 8 ESX hosts and vCenter 4.1.  Most VMs are Windows member servers, but also several RHEL servers and a few non-domaine joined Windows servers.  We have also two domain controllers that are already virtual machines.  I'm down to the last physical domain controller which is our role PDC FSMO server so the Master Timekeeper.

  That's how I was going to change our Setup for the services of time with all being virtual domain controllers.

  1. the virtual FSMO PDC of our clocks of field it is time via w32tm to an external time such as us.pool.ntp.org source. That's the only DC with an external time source.
  2. all the domain joined machines Windows, whether virtual or physical (servers and clients OS) get their time via the domain controllers.  PDC-> all the other DCs-> clients and member servers.  On VMS, we do not use VMTools do a time synchronization. Throughout the normal Windows AD process.
  3. all ESX hosts serve time source external PDC, described above.
  4. all the non-domaine attached (Windows or Linux) machines that are virtual machines get their time synchronization via the VMTools Sync feature.
  Have I not my correct thought and not its ok to ensure synchronization of time between the field in a virtualized ad environment?
  Thanks in advance,
  HR

  That sounds about right, and I've implemented almost identical to this designs. The key is, as you say, do not sync using the time host via VMware Tools, in particular on the role of the PDCe.

  I also usually use this method to ensure that the PDC (role 5) is the only way to an external time source:

• How can I move the CRA over time default text?

  I have placed "Default Text" on a separate video track. In the video, a hand is oriented along an arc for 1.5 seconds.  I want the text to follow the CRA that the hand moves.

  I stumbled on how to do this all by pointing and dragging various things in the framework, then I screwed up the edit and CTRL-Z got myself back to a better point AND I LOST THE ABILITY to do so.

  While it worked, I would see my text in its framework, and the center of the image has a cross.  By positioning the scrubber at the beginning and ending points, there was a line drawn from the cross to the text.  The starting point was a line showing the starting position, the point of arrival had it showing the end position.

  Now, when I try to move the text, I get one of two things (none of them work for my plan):

  (1) I have the window "Settings" open and the pointer tool is used to fix the position of the text in my "Default Text" setting.

  (2) I'm moving the entire frame in the preview window and the cross moves with it.

  I stumble on something and I don't know how I got there.

  Thanks for any help you can give.

  Great news. Great job.

  Timeline clip selection, Panel applied effects tab/Applied effects Palette/movement extended to get across (to zoom) and properties of Position (panoramic view).

  That's where I was pointing you in my previous post when I wrote

  But if everything you want to do is to move text along a path in Premiere Elements, which can be done Motion Keyframing scale (to zoom) or

  Position (panoramic view) / probably better using this framing key to the Position property. Have you tried yet?

  There is always another way... creating keyframes for Position at the level of the "elastic" timeline, orange line that scrolls horizontally on a video editing or audio clip. More info on another time if you are interested.

  But, at present, a lot of progress.

• The maximum graph time

  I need to draw a picture that shows the behavior of the frequency of the peak spectral of the signal over time. I thought that this VI will work fine:

  

  The interesting thing is that before you plug the output of statistical Maximum of the block time to the time of Max graphic time, displaying the parameters correctly:

  

  Here's the diagram corresponding to the façade above:

  

  But as soon as I connect the Max permeate more graphic time to the output of statistical Maximum block time and run the VI, the time (x axis) of the chart changes frequency x axis:

  

  Once again, I want to the chart to view the changes in the value of maximum frequency over time. Any suggestions? I have attached the VI below. Thank you!!

• Over time fill color

  Hello, I am working on an audio model. I'm doing a waveform similar to that which you can see soundcloud. I managed to program an expression to generate the waveform. But I have a problem with filling the waveform with a color based on the time. For example, see you on soundcloud how the waveform fills orange along the song? This is the concept, I am working on that. Here's what I have so far:

  

  I want the blue bar to move to the right over time, but I want only the white parts of the wave to turn blue it progresses (the rest of the hidden solid blue). How would I go to do this? My knowledge in After Effects is limited, so any help is GREATLY appreciated! Thank you

  Please let me know if you need more information

  So just to clarify you are trying create a representation of levels for the duration of an audio file and not an animation audio frequency analysis. If that's what you do just before compose hundreds of layers, or nest the comp in your main comp, then use the cache by approach. If it was me I would probably just import the audio layer in the comp, press the L key twice to reveal the audio waveform, press on the ~ key to make complete timeline screen, expand the waveform, take a screenshot, add the screenshot to the model, apply Keylight, then add a shape layer below the screenshot set the screenshot as a reverse alpha cache approach for the animated gradient and be done with it. This model should be nested in my main computer to complete the effect.

  

  If I wanted a different look for the waveform I edit the screenshot in Photoshop or use a Premiere Pro or any other program to capture a screenshot of the wave. Since you did all the work of your hundreds of layers I just would compose before them, place a layer of shape with a gradient animated below the pre-comp and put in place the track matte.

• How to adjust audio speed/duration over time?

  I watched a video on how to adjust the video duration and speed over time, using time remapping and keyframes, but it doesn't seem to affect the audio for some reason any. Is it possible to adjust the speed/duration of the audio over time as you can do with the video?

  No, you need AE for this.

• How to make a game to replenish his life over time?

  I tried to write codes in my game it reconstructs the life of the player over time.  But I had no success. For example, in Candy Crush, it's called 'life '. You have 5 lives to the fullest. And once you start a level, he removes 1 5 life point. And then the timer next to the label of life begins to count down from 20 minutes to 0. Once it reaches 0, it gives you 1 point of life back so that you can restart a level. I tried to do it like this: stop Frame EventListener countdown from 20 minutes to 0 whenever the number of life is less than 5 years, and once it reaches 5, numbers count. It sounds simple, and it's simple. But what happens if the player leaves the game so that the countdown timer? Let's say the player to the left of the game at 15:10 with 3 lives and reconstruct the 10 min for a life left. And the player starts the game again at 15:30. The player would then 4 lives and rebuild 10 min for a life left. I tried to do by using the date class. But the remaining time is wasted when I left the game and restart the game.

  Instead of an absolute time countdown, count until you reach a maximum and dispatches an event when the maximum is reached. Have a separate object that stores the number and can be initialized at any point. When the user leaves the program, store the former total. When they start again, initialize a new instance of the object of the County with the old County. Display the countdown, if necessary, by subtracting the present value of the maximum value.

  If your object might look like this:

  Counter/public class extends EventDispatcher {}

  protected var _count:int;

  protected var _max:int;

  protected var timer: Timer = new Timer (1000);

  public void Counter(count:int=0,_max:int=20):void {}

  _Count = count;

  _max = max;

  }

  public void start (): void {}

  timer.addEventListener (TimerEvent.TIMER, incrementTime);

  Timer.Start ();

  }

  public function stop() {}

  timer.removeEventListener (TimerEvent.TIMER, incrementTime);

  Timer.Stop ();

  }

  public void incrementTime(e:Event=Null):void {}

  _Count ++;

  dispatchEvent (new Event ('countChanged'));

  If (_count == _max) {}

  dispatchEvent (new Event ('countIsMax'));

  possibly could reset _count here

  }

  }

  public function get count (): int {}

  return _count;

  }

  public function get max (): int {}

  return _max;

  }

  public function get count (): int {}

  return _max - _count;

  }

  }

  Its use might look like:

  SerializableAttribute public class votrejeu extends Sprite {}

  protected var counter: counter;

  protected var life: int;

  public var countText:TextField;

  public var livesText:TextField;

  public void YourGame() {}

  Super();
  logic to retrieve stored here number

  counter = new Counter (storedCountThatYouRetrieved);

  counter.addEventListener ('countChanged', updateCountText);

  counter.addEventListener ('countIsMax', updateLives);

  }

  protected function updateCountText(e:Event):void {}

  countText.text = String (counter.countDown);

  }

  protected function updateLives(e:Event):void {}

  life ++;

  livesText.text = String (lives);

  }

  }

• Increase video exposure gradually over time

  So, I made a timelapse in which photos is receiving more light to begging for more dark at the end of the day, because the natural light conditions also changed. I couldn't change the shutter speed, iso, openness throughout the process, as it has been set to manual. Is it possible to add an exposure effect that could change the exposure over time, gradually as a result of 0 to + 5, to compensate for the video to penetrate slowly more dark. I hope you get the idea. Or I have to manually change exposure from sources including ar images darker before making the timelapse video. Thanks in advance for answering the question.

  Add an adjustment layer for your offsetting effect, then:

• How to check the platform below, that the application will work over time?

  Hi all

  Is there a way that the application can check the app was supposed to work on what operating system. Say if I use an OS 5 and then the app was built for the 4.5 OS, so I need to check whether the application is a version 4.5 and inform the user and halt execution. I can change the appname or version number to detect but y at - it another way to do it programmatically.

  guys sorry for the stupid question. I had some caffeine. and resolved immediately. I used the preprocessors.

  Thanks for the help guys. I understand your desire to help me. Thank you
