slow simulations with signal source

This simulation works well, but then he suddenly stops! Can anyone shed light on what this may be?

Hello

I found that the simulation stops. I found that it slows down considerably when out of XFG1 is low. This event seems to cause some difficulties for the Simulator. Helps loosen the tolerances of convergence. Go to simulate-> Interactive simulation-> scan options settings-> Customize. I suggest the following settings:

ABSTOL = 1e-8

VNTOL = 1e-4

RELTOL = 0.01

Thank you

very slow niswitch with signal connected (PXI-2535)

First time using a switching FET card, running base vi where I connect a line and two columns, and make a measure of resistance with a multimeter.

I found that with the digital multimeter connected, IE the applied signal, the switch may take more than 5 seconds to close. (Ohm DMM reading 26 ohms after 5 seconds, the 'debounce expectation' although all good reported vi)

If the DMM is not connected, sometimes instantaniously. (disconnect the DMM, perform the trigger, connect the DMM - instant closing)

Anyone experienced the same thing?

Found the problem.

Seems the FET card goes into protection mode if you do not connect the DMM - signal to the chassis GND.

After that, it worked fine.

Weird behavior with Signal to simulate and loops

I'm having a weird behavior with Signal to simulate and while loops. Attached a photo of my program. The problem I have is that when I use Stop to stop inside while loop, then use to restart the inner loop, simulate Signal instantly generates a bunch of points of data between when I pressed Stop and Go. By example, if I stop for 5 seconds, wait 5 seconds, then press Go, it will instantly generate data for t = 5 t = 10. What I need is for the generation of signals to stop when I press stop and continue where it left off when I press Go. How can I accomplish this? I have no idea why he exhibits the behavior described in the first place.

Hi optometry.

Can you give us a screenshot of the configuration window for the VI express to simulate signal? I was able to reproduce the problem when I used "Simulate the time of acquisition" at times, but the VI's are featured as you described you wanted when I used "run as fast as possible." Have you tried this setting?

PC running slow increadibly with 128 MB of RAM - recommended to increase the RAM

Original title: pc running slow increadibly with 128 MB of RAM

My mother's PC runs incredibley slowly.
After you perform a clean installation of win xp and addition of firefox, and avast antivirus, pc still increadibly slow.
His laptop is a HP Omnibook xe4100 and has 128 MB of ram.
What I do need to update the ram of the laptop computer or is the problem of something that can be fixed with software recording cleaning?
Thanks for any help on this!

If you did a clean install, it is not the registry slow down your computer. A clean installation removes all and back windows on the system with just windows files, so the registry is only what is absolutely need to run.

128 MB of RAM is incredibly low, so even if the slowness is caused by something else, you should buy more in any case, because it will help the computer a little.

screenshot of my Simulator with my running app

How to take a screenshot of my Simulator with my application running on it.

Reason, I need to screen shot of my application, but don't want to recreate and resize everything on photoshop just for a screenshot. Any help would be thank you very much.

If you are on Windows, press print screen on the keyboard, start MSPaint and paste the image into Paint... You can crop then just to the Simulator window = should be pixel-to-pixel because simulator is not resizable. I hope this helps.

Slow WiFi with Broadcom 4322

After upgrading my laptop HP DV7 with Windows 8, I found my wireless connection was extremely slow. My card is a Broadcom 4322AG. This seems to be the same problem as has been in the forum

Slow WiFi with Broadcom 4322 and Windows 8 CP.

Following the advice in this forum, I changed to TKIP AES security and everything seems to work properly.

Thanks a lot for sharing your solution! My problem was that I downloaded at least 1 Mbit/s and transferred approximately 15 Mbps. Then I changed to TKIP, just as you said and now I'm moving 21 Mbps of download and 19 Mbps downloading. All this on a MacBook 5.1 :)

clone then target trying to make contact with the source

Hi all
Some strange behaviour in the land of Oracle today...
After a clone (managed, for the most part), we get alerts of the suite that tries to make the cloned instance of monitoring network contact with the source instance. As soon as I disable Apache alerts stop coming, so I'm halfway to understanding the problem.
Can anyone think all the configurations that I missed? I searched the usual places (httpd.conf etc) any reference to the PROD, but nothing appeared. If Apache is somehow trying to contact the server of PROD, does anyone know where she can be configured?
The connection between application layers - separate database levels are fine.
Our version is 11.5.10.2
The servers are RHEL 5.6
DB is 11.2.0.3
Thank you very much.
(Autoconfig has run ok, everything works fine - just the annoying fact that I can't put back the environment yet!)
DA

Hard to say, but since the original question was in the Web server, it could be a separate issue. Still, it might be linked to the root cause. If you access another environment (on another server), it MUST be something.

Preclone did run OK on the server database AND middle-ware? (on the source)

Did you manually run FND_CONC_CLONE. SETUP_CLEAN? (on the target)

Did you run the cmclean.sql file? (which could resolve the name of the source server in the managers of the conc.)

What is in ORATAB?

With the help of any alias servername?

End of Cup Video Clip off the power when send you first Pro CC 2014 to effects after 2014 CC and I slowed down with Timewarp?

Try adding effect temporal Deformation on an adjustment layer in AFX, rather than on the video it self.

Mapping of several columns in the source in 1 target with the source Excel file
Hello

I use to load Excel files in HFM FDM 11.1.2.1.
In Excel, I had 3 columns that need to be mapped in 1 column target using a few rules and mappings. Forest to source file should work in all cases.

For example,.

Source:
A, B AND C
1 company 1 xxx
2 yyy Company2
1 Company3 zzz

mapping for B:
Company 1 C1
C3 Company3

mapping for C:
C2 Company2

target after confirming:
C1
C2
C3

I take data from B or C according to data in A (1 or 2).

I found several ways to do so, but they are not perfect:

1 map columns B and C to the correct value (#C1, C2) and use scripting conditional on a column (for value correctly mapped either column B or C).
The problem here is that I can not break through the low PIF when B and C are mapped to values other than [none]. Can this been bypassed?

2 use DataPump import Scripts for concatenating the sources in one column only and use the tables mapping standart on 1 column.
The problem is that DataPump import Scripts do not work with the source files Excel. Is this correct? I could find a word in the documentation...

3. map columns B and C [None] script well but fat on the column, as:
If (varValues (13) = '1' and varValues (39) = "Company1")) then
Result = "C1".
ElseIf...

Which is horrible, and it would be very difficult to add new mappings in the script. But it works.

4. logical accounts. I can't use it I need to drill down.

Could you recommend me some better way to do this simple task to work?
It's a bit that I coded something like that in VBA, so you will need to do a bit of cleanup; However, it should get you well in a way that might work...

Why not add a formula in the excel file, once it is downloaded? (I guess the excel file that is being loaded is not something that you could develop a formula to start?)
```
on error resume next 'make sure all commands are executed.  If something happens in code and file is open, we don't want to leave it open...

Set objExcel = CreateObject("Excel.Application")
Set objWorkbook = objExcel.Workbooks.Open("")
Set objworkSheet = objWorkbook.Sheets("")      'OR you could use ordinal

objExcel.Application.DisplayAlerts = False
objExcel.Application.Visible = false

for x = 1 to 100   'I'm just doing a loop for the sake of doing a loop.  You might want to loop through rows and for each row that has a
      'value in col A, make the formula and then break out of loop so you don't add a metric ton of unnecessary formulas
    objworksheet.Cells(x, "C").Formula = "=A" & x & " + B" & x      'i.e. =A1+B1
next 

'Save the changes
objWorkbook.Save 

'Close the workbook
objWorkbook.Close

'Quit application  (important)
objworksheet = nothing
objworkbook = nothing
objExcel.Application.Quit
objexcel = nothing
```
NOTE: Microsoft DOES NOT officially support office (i.e. what we do above and what of FDM backstage I guess) seems to work very well, but in most cases, etc.. Be careful about cleaning to ensure that all memory is released and that the instance of excel stops.

Extremely slow performance with Radeon HD 7870

Hello
I use a number of Adobe programs on my new 64 bit system of Windows 8, with 16 GB of ram, a processor Intel Core 2.67 ghz i5 and AMD Radeon HD 7870 2 gig. All programs (including After Effects and Illustrator) work very well with the exception of Photoshop CS6 64 bits, which is extremely slow performance with GPU to use enabled in my preferences (Photoshop selects by default). If I disable the graphic processor use, this slowdown faints. If I change the Basic Design Mode, there might be a slightly detectable improvement during Normal and advanced, but it is still horribly slow. The refresh rate seems to be only a few frames per second. Everything is slow: brushes, zoom, panoramic, as well.
I tried changing the settings I've seen suggested elsewhere: I went 2 level of Cache, history says 10 and the size of the tile to 128 k. No effect. Photoshop is currently the default using 60 percent of available ram. Efficiency has remained 100% overall of all my tests. In addition, this slow performance touched me from the moment that I installed Photoshop; It didn't arise after previous good performance. The problem exists regardless of the size or the number of documents that I opened. Performance is always terrible, even when I create a new blank canvas of 500 x 500 pixels and try a simple task like drawing with a brush.
Photoshop is perfectly up to date, and so are my graphic drivers (Catalyst version 13.1). Any help would be greatly appreciated; yet performance is so bad in Photoshop it is unusable, graphic acceleration activated. Thanks in advance for the answer.

I use Catalyst 12.8 pilots at the moment and have a Windows 7 system and have a remote access utility called Radmin installed, but I don't know if seeing that Microsoft based Render driver is provided on Windows 8. It seems that this could be the key, as the basic OpenGL implementation of Microsoft is made all in software. If somehow driver Microsoft took control and you don't get really the GPU acceleration, then that would surely make things really slow.

Rafaello, you have updated drivers... You can post your top of your system information again?

Have you tried a full, complete deletion ATI driver and reinstall from for example, 13.2 beta? Here is the removal of ATI tool:

Slow simulation time.

I was wondering if there is a way to improve the performance of the simulation. I had made some changes, but still slow model execution.

I have the similar model on simulink that works almost instantly, but in LabVIEW, it takes a while.

PS: LabVIEW 2015.

I looked in your simulation and tried various changes to speed up the process. Tried different solvers and values, but apparently not much can be speed up because:

(a) your signal a 'burst' (oscillations around a value) which are of very high frequency;

(b) you are simlating for a last big time (86400 s)

(c) you collect data each ' continuous timestep.

Here are a few suggestions to try to make it's faster (other than to use a faster machine...):

(a) try to increase the maximum Stepsize from simulation to 10000. This will allow the Solver to skip stages more great if he can (there is some linear parts on the system)

(b) try to reduce the final time. Now you have 15 ~ swing that seemed to be the same. If you allow just 4 (as 25000), this would make it faster.

(c) try to make the 'collector' discreet and set a value which will capture the information you need. Fewer points to caption, faster it would work.

(d) try the 'rigid' as the Rosenbrock or the BDF Solver. Those who seem to be the best options in question.

With these changes, I was able to simulate the 25000 in 4.1 s and with all s 86400 in 13.4. I use a Dell computer (Intel Xeon CPU E5 - 1620 3.70 HHz 3.69 GHz with 32 GB of memory).

Very slow even with instances.

Hi all, I am trying to compress a bunch of my own videos to save space. I have the compressor 4.2.2 on El Capitan 10.11.5, latest version of the software. My specs are:

iMac 5K end 2015

4 GHz Quad Core i7, hyper threaded to 8 logical cores

32 GB of RAM

AMD Radeon R9 M395X 4096 MB

I export source H.264 in MPEG-4 h.264. I'm very slow sometimes, and this becomes even slower when I add an instance. Also, I edited the .plist preference file for the compressor and added more cases that I have been authorized by default because it was not maxing out my CPU. If I have 1 instance (as the compressor allows me) or 4 instances (which uses 90% of my CPU in the activity monitor), it seems much slower than the single instance. Why? My iMac is the most high-end model and a 8 logical cores, how is it unless its slow export when I use more instances? Its already very slow with just a single instance. How to speed this up?

The Mac Pro is the most high-end model. When transcoding to H.264 format, use not all instances. The CPU has a built-in H.264 encoder that uses the compressor. So bodies indicates compressor to ignore that and just do it via the encoding only software. The speed you get is the speed you get. Without knowing the length of your videos, what are their original format and the codex, or how long they take, I have no way of knowing if your Mac is slow or if you expect too much of him. This information would be useful.

Working with the source audio 5.1

Can anyone recommend a good resource / tutorial on the use of origin in FCP X 5.1 sound source?

Scenario: My new camcorder from Panasonic SC-V770K 5.1 surround audio recordings. I found that, in some areas as small theatres the rear channels pick up lots of unwanted noise, echo and the crowd.

What I would do in FCPX is to adjust the levels of the rear channels down to focus on the audio to the front.

But all the documents online and tutorials I found describe how to create a new 5.1 mix, not how to edit an existing levels. Surround 5.1 panoramic options are esoteric and not well documented, and all seem to place the existing channels at current levels in new 5.1 investments. Out the sound of the clip in 6 mono channels is slow work and means that I have to adjust separately and filter all the. 'Mono stereo + 2 2' and '3 StΘrΘo' options are not well explained, and if I switch between them I lose all my settings.

Any help or advice on how to change an existing 5.1 audio track?

More specific example: how to adjust the levels of the surround channels in a clip with audio 5.1?

If I change the audio channel of the Mono 6 element I can individually adjust the level of each track, but the surround mix is lost and they are all pan in the Center. I have to manually the value each mono track stereo Pan, pan L/R and set levels. Great for a clip but there is no apparent way to automate this.

If Pan Mode the Surround video, I can fix the respective rates of mixture and pan toward the Center with Attenuate. It is the closest, I came if they support Centre at the expense of the L/R.

Is there an easier way to take a track existing 5.1 and say 'just turn this channel up/down '?

Slow connection with the built in WiFi card

I have a connection wanadoo adsl internet 20 Mbit family with a direct box. The box is also a wireless router.
When I connect to the livebox with my toshiba mx40-231, the connection is very slow. The connection is constantly switch between 1 Mbps and 54 Mbps and speeds range between. It is also the problem. One moment an internet page is send in 1/10 of a second and 1 minute later a page to load in 20 secconds! the strang thing is that the intensity of the signal is constant high!

With the direct box, I also had a wireless USB key. When I use this stick I get a connection very quickly 54 Mbps constant.

It seems to me that the construction of the wireless card is the problem. I already have the latest wireless driver and tried a few channels on the router.

Someone at - it an idea to solve this problem so I can throw this wireless stick :-) Thing very clumpsy this stich on such a portable wireless of beautifull!

Hello

If you check the wireless card, you will find many topics on this subject. We know that Intel 2200 B/G card wireless make disorders and connection is not constant. We can only speculate why this happens, but the fact is that this card has problems with different routers.

For example: Satellite M40 has the same card and the fantastic work with Netgear router. Even with Belkin, it works well in full speed.

I recommend you to install the latest version of the driver Intel

Good luck

Super slow Mac with spiral spinning, please help

My MacBook Pro runs very slow for some time now. I have removed many files on my external hard drive and that what I need there. Most of the tasks take longer that it should and I see the spiral turning almost at every click. Help, please!

I did the check of the being, but I'm not very tech savvy so have no idea what to do with the news. Any help would be greatly appreciated
