Hi all, The problem is on the volume of the voice sent by the SPA-841. I think the echo cancel algorithm sets a limit to the microphone when detects sounds or noise from the earphone. This problem generates an oscillation on the voice volume sent by the phone and even turns it off completely for very little lapses of time making the communication very uncomfortable. I manage three different implementations with Asterisk and Sipura SPA-841 on different clients and network topologies, and on every one we are exp...

Hi all, I have just got going with R and think it is really nice however, as far as I can see, it can't do what I got it for: I have some output from a computer simulation of mutating genes represented by a biological statistic - so the graph looks roughly like the top of: x = y^2 - with oscillations around the general curve. If I use scatter.smooth() I get a nice curve representing the oscillations but what the curve I want to fit is the more basic curve ie the top arm of the x = y^2. Any suggestions?

Has anyone seen this problem before? I have a server with a single X100P card. The audio level is a low, but if I raise the gain to more than -2db (Rx + Tx) it starts to oscillate in an echo test. Not at a high frequency but with a noise that is best described as a steam engine starting up. It then starts to clip and crackle. If I bring the gain down to Rx=-2.0 and Tx=0.0 or lower then it settles down but it is very very quiet. I have tried the latest CVS Head with echo...

Hi List, I have a time series of 122 values, actualy it is a time series of daily indian monsoon rainfall. now i want to filter this time series for a particular oscilation say 10 to 20days oscilation. i want to find out what amount of variance is explained by this mode. Which package is available in R for this purpose. and how to calculate nquest frequancy of this series. any help is much appriciated. thanks in advance anil ANIL KUMAR( METEOROLOGIST) LRF SEC...

...s of some periodic data. I have an output from measurement each minute and this output is modulated by rotation of the equipment (approx 6.5 min/revolution). I can easily spot this frequency from spectrum(mydata, some suitable span) However from other analysis I suspect there is a longer term oscilation (about 70-80 min) I am not able to find it from mentioned data. Plese give me some hint how I could prove that such long term modulation of my data exist in presence of quite strong modulation by this short term oscilations. Thank you Best regards Petr Pikal petr.pikal at precheza.cz

...ata from CO2 measurement experiments. I don't want to reinvent the wheel, so before I start custom coding in C, I'd though to look around a bit and bumped into R on freshmeat. basically, it is a 2-column data sheet, with timings on col1 and CO2 value on col2. These value have a pretty nice oscillating nature, with some occasional false spikes. the analysis simply means extracting the 'ceilings' of the curves = the start-end times of the top of each oscilation. my Q to the mailinglist is now : can such analysis be done in R ? Or is R not the appropriate package for this kind of st...

First, thanks to all who helped me with my question about rescaling axes on the fly. Using unlist() and range() to set the axis ranges in advance worked well. I've since plotted about 300 datasets with relative ease. Now I'm trying to fit a lossy oscillator resonance to (the square root of) a lorentzian (testframe$y is oscillator amplitude, testframe$x is drive frequency): lorentz <- nls( y ~ a0 / (Q*sqrt((1-(x/f0)^2)^2 + ((x/f0) * 1/Q)^2)), data = testframe, start = list (a0=1.4, f0=84321.6, Q=600000)) and am r...

Greetings, I have several sets of oscillation data and would like to estimate the parameters of a sine function to each set (and hopefully automate this). A colleague provided an excel sheet that uses solver to minimize the RSS after fitting the sine function to each data set, but this cumbersome and difficult to automate. Is there...

Hi R users, I have collected data which I plot(x,y).The problem it has oscillations. Now i'm trying to "make better" this curve with a smooth line starting let's say @x=300 s. And then collect my new datas. But I don't know how doing this. Perhaps a linear regression ?? See .jpeg foto. Thanks for any help it will be given. http://www.nabble.com/fi...

...FS in Gigabit applications? I've try read large file (45GB) from server to client's dev/nul and don't get bandwidth greater than specified... But, using FTP or NFS I get REAL stable read speed at 80 MB/sec! Same picture in synthetic TCP tests. Why while SMB in use network utilization oscillate around 25% and nothing more? Is that mean that in 10GbE we get max utilization in 2-5%? I tested various combination SAMBA server/client, MS server/client - all for nothing.

...HP DL585 with HP EVA SAN storage. Linux is CentOS 5 on a Sun X4200 with samba package samba-3.0.25b-1.el5_1.4and a FUSE mounted filesystem (glusterFS). Watching the network tab of task manager while pulling a few large files from the samba server to the fast drive on the windows end I see an oscillation between 50% (of gigabit) and 0%. A trace captured on the linux side and analyzed in wireshark corroborates, periods of high throughput alternating with periods of near-inactivity. The periods are roughly of equal length, usually between 4 and 8 seconds. As far as I can tell during the...

...among clients regardless of its current link speed? I have a link that can get bursty at times. At any given time the N active sessions (the ones with non-empty queues) need to be serviced simultaneously, each at a rate of 1/N''th of the link speed. My case is an internet connection that oscillates between 96 kbps and 256 kbps. I cannot predict the connection speed in order to use the classical HTB (to set up a 96/96 kbps class), because I would loose a lot of bandwidth when the speed goes over 96kbps. This might not be a strictly HTB related question. It doesn''t matter if I us...

Dear list, I apologies first for my English, hope you will understand well my question. I am working on 1/2 hour piezometric data, time unit is second. They present daily oscillation when using the spectrum() function. What I am really interested in, is to find the amplitude corresponding to this oscillation. I work with a college using Matlab, and although we apply the same methodology, our results differs : we find the same frequencies, but not the same amplitudes....

I have release my routines for PRI circuit monitoring. You, your client or anyone can be notified by phone, beeper, email or txtmsg that your circuit is down. If Asterisk crashes due to an oscillating circuit (as I have found it sometimes does), sendmail is usually intact and email notification and txt messages will usually get through. If the client has backup lines, and Asterisk remains up, calls can be made supplying all the information necessary to initiate a support call to the carrie...

I am having a hard time interpreting the phase and coherency plots. x is two timeseries that occur at the same time i.e. a b 1 11.2 12.3 16 11.3 12.4 31 11.4 12.5 46 11.5 12.6 ...etc even though my example is does not show this they are oscillating at more or less the same frequency just shifted by t=x (imagine two sine waves offset with the 2nd sine wave starting at the peak of the first). I would like to know what x is. I think I am looking for the phase shift? The coherency? Cross-spectrum? And I have read the help files, Shumw...
