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

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

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

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

...able 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

Hi all I'm a programmer at the psychology dept, and last week, I was asked to write an application to analyze some result data 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.

I am experiencing some problems at working with lists at high level. In the following "coef" contains the original DWT coefficients organized in a list. Thorugh applying the following two commands: coef.abs <- lapply(unlist(coef,recursive=FALSE,use.names =TRUE),abs) coef.abs.sorted <- sort(unlist(coef.abs),decreasing=TRUE) I get vector "coef.abs.sorted" containing

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

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 a method in R for fitting a given sine function to a

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.

Hello, I use rsync to mirror the home directories of users on a computational cluster for backup purposes. There are users who have single directories containing 12,000+ files. I am using RHEL 4.0 update 4, and the rsync is version: rsync version 2.6.3 protocol version 28 When rsync is deleting the files in a directory with 12,000+ files (i.e. when the directory was removed in the

Hi honorable people! In self-education purposes only, I would like to ask is 35 Mbytes/sec bandwidth limitation of SMB/CIFS 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

I've run into an odd (at least to me) performance issue between a samba server and windows 2003. The windows side is w2k3 w/ SP2 on an 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

Hello again, Is it possible to split a bandwidth equally 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

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

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,

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
