• How does the Daubechies Wavelet - 4 VI actually work?

  Hello

  I'm a student working on my final year project, one of the objectives is to detect the peaks of the ECG (R - pics) signals using the Daubechies Wavelet - 4 VI in LabVIEW. I am current using 2013 LabVIEW student edition (6 months trail), if that makes a difference.

  I'm quite confused on the wavelet of Daubechies-4 works:

  (1) levels how it decompose the signal in?

  (2) is there a way to adjust the level of decomposition?

  (3) are already applied in the VI filters or do I really need to design a filter myself?

  (4) what is the main difference between a Db4 PtByPt and a normal Db4 transformation in terms of LabVIEW?

  (5) Finally, how the VI actually superimposed on the signal Wavelet? Should the entire signal into account or should I take each pulse into consideration when the superposition of the wavelet?

  Thanks in advance for the answers.

  Kind regards

  Hi Karine,.

  I was absent for the whole of last week, so I only read your answer today.

  The Wavelet Transform Daubechies4.vi you mentioned is indeed already included in LabVIEW (minimum full version, which is what offers Student Edition). From what I see, it's a very simple implementation of the transformation that the VI I mentioned in my post above. To better understand how it works, read first to the top of its help file (use ctrl + h), then open the VI by double-clicking on it to see the block diagram. From there, you will see that this VI essentially multiplication of matrix of coefficients db4 to the signal. That being said, we can go back to your questions:

  1. level of decomposition

  We see on the block diagram it's code to be a number such as recursively signal can be decomposed again by 2, for example signal length of 8 will have 2 iterations. You can change this setting by simply copying the pattern-block away and customize your VI, as long as you know what you are doing.

  2. the filters

  These are already applied in the VI as coefficients has explained in the help file and as seen in the block diagram.

  3 difference with his release Point by Point (PtByPt)

  They work in a similar way, but the calculation is done differently. The normal version uses the analysis based on the Bay and so buffering, then the analysis point by point is a new paradigm where input-output analysis is done continuously in real time. This is necessary for the deterministic real-time high-speed systems. If you open the VI, you can see that at the heart of it, it uses normal Wavelet VI for the análsis but bounded by a few functions to handle the case point by point. For more details, see the help of LabVIEW (ctrl +?) and read the analysis Point by Point.

  Finally, the Wavelet Transform Daubechies4.vi takes the entire signal into account, as can be seen in its block diagram.

  I hope this helps.

  Kind regards

• The firewall of windows 7 actually works? I tried to block certain IP addresses; He does not

  Original title: firewall

  The firewall of windows 7 actually works?

  I ask because I tried to block certain IP addresses; I created a rule for outbound custom where I entered the IP addresses and set it for all applications. However, when I go on a website, I see using TcpView IP (s) I created the rule for is connected (established).

  My question is how to use Windows Firewall to block the IPs, or is that not possible?

  I have re-installed Windows.

  The problem is resolved.

  Thank you

• Satellite L20-153 may not get the WLAN to work

  Hello world

  I have a problem with my laptop wifes that I've not been able 2 fix.

  Its windows had crashed and wouldn't start in 'BACK' keept marker just flashes and nothing happened, I tried to restore to later work windows, but that did not help, nor the integrated security mode. So I took out the CD/DVD recovery and tried to do a new installation, the configuration of the installation has functioned well until he asked me 2 remove the disc and restart the comp I did.

  When it restarts the same problem appeared (flashing marker and nothing happens).
  So what I did I took a normal windowes XP (SP2) and reinstalled eveverything (I formatted the drive also) and rebooted and it worked.

  2 my next challenge is 2 get all the hardware working I got all all work, but the WIFI network (integrated).
  After I installed everyting I saw my network wireless but next time I started the comp, it disappeared along with all other WLANS that I use to be Alba 2 see. and when I still have refreash sound empty.

  I tried to disable it and then turn it on again but it doenst help.

  I also tried once more to use the Toshiba recevory drive but you have the same problem.
  So now I'm back with my windows Xp is installed, but I can't get the WLAN to work.

  There isn't any conflics material.

  So now I need your help about how to do 2.

  tanks a lot.

  Kind regards

  Hello

  On WLAN, there is actually no philosophy, and few things are important:
  The wireless network card must be installed properly (properly listed in the Device Manager) and
  It must also be enabled. Initially with switch WLAN (WLAN light is on) and then activate it by using the FN + F8 key combination.

  After making this key WLAN card should see all available wireless networks. To connect to one of them is another theme.
  To be honest I didn't understand exactly what is happening. If I understand you right your laptop can see WLAN but after reboot all available wireless networks is not visible. Am I right about that?

  Have you tried rebooting your WLAN router and restart analysis the WLAN area?

  It's a delicate issue... like some patches cannot stipulate pitchbend...

  But to quickly test your pitchbend wheel actually works properly...

  Download the free lunch monitor...

  Run and see if it sees pitchbend data sent by your keyboard... and therefore by logic.

• Cisco ask the Expert Award winner - 7 October - thank you Cisco!

  Hi all

  I don't know if you had the chance to join the ask the Expert Live recent event with Lucien Avramov. I did, and guess what? I won a free subscription to Cisco Live virtual environment!

  I'm a little ashamed to say that I used a bug in the rules of the game to win. Know everything and then during the presentation, we were presented with a survey question and poll participants had a chance to win such a prize for each question. I downloaded the PDF and read the rules. It seems that the first person to answer a question would win. You can guess what happened then. I started by clicking on the radio buttons before reading the content. I replied that I have never heard before NX - OS. At this point, I think I heard one of the people to say Cisco "we already have one"never heard "! I don't remember the last time I laughed so much. I hope that my hotel room was really soundproof. In the next question, I think that I said that there are more than 60 Nexus in my environment! Now it makes sense!

  I think I've won more than once, but the rules did not have so many bugs and there is a limit of (1) price per participant. Cisco is likely to change the rules (randomizes) next time if they want honest answers. However, it has been a great experience and don't miss any future events. You never know what the father Christmas of Cisco is there for you!

  Cisco thank you! Thank you very much!

  Kind regards
  Maria

  Maria,

  I can always count on you to find a way to game the system I'm better to our administration tool to make sure that all your CSC are legitimate I have passed along your feedback to the team dealing with this event.  Looks like they need work on the rules.

  See you soon,.

• Will make the creation of work on my pc with the following components?

  A friend will build me a pc (budget) to work with premiere pro, I sent him the list with the specifics of the site and he returned me the following components which, according to him the system will work: CPU: Intel Core i5 3EGeneratie Moederbord 3470: ASUS H61M-K (Micro ATX moederbord) DDR 3 (8 GB) 10600U no Ecc Unbufferd Hitachi 320 GB SATA schijf herd 7200 RPM

  Because he is not an expert on the video editing I want to know if anyone here knows of that is just and that the components don't we eventually Miss?

  Xcuse for my poor English...

  Mario,

  Your price beach you will have to do serious, if not serious, sacrifices in performance in three main areas (CPU, GPU and disk i/o and possibly enough RAM) even if you buy used - you'll find yourself with limited and obsolete PC or a new PC not comply with standards. This is because it is still used, a PC that is very satisfying for first Pro have you would cost at least double what you intend to spend.

  That said, you might be able to use this old Ivy Bridge PC that you listed in your original post if you can run a cheapo edition consumer program such as Premiere Elements, like most consumer editing programs do not anywhere close to take full advantage of the potential performance of the high-end with new platforms CPU PC.

• How the cloning process works in the background?

  VMware dear Experts,

  I want to know "How the cloning process works in the background?", according to my understanding is it works like this

  (1) instant a VM cloned

  (2) recording a virtual machine to a destination host

  (3) copy the hard of the files to a destination host

  (4) commit the Flash disk to the destination host (changed blocks r commited)

  Peut sum1 brief the cloning process...

  Concerning

  Mr. VMware

  Almost correct, step 4 the Flash disk gets committed to the VM source not destination of VM, does start with a hot-clone vCenter no change after the clone operation (i.e. the snapshot has been added to the source of the VM) will be written to the destination virtual machine.

  If you use VMware Converter, it has an option to "sync" can you consult so that it does several passes to pick up all the changes of the past during the clone operation.

  One more thing to remember it is hot-clones consistent crash so there is the possibility of losing data, although from my experience there has never been a problem.
