Vibration signal prediction in R
I have a vibration signal coming accelerometer. I converted this signal from* m/s^2* to *mm/s*. Now I am supposed to predict this vibration signal in R using historical data. (Please see the attached picture of vibration signal). Can I use this vibration signal just like that to the prediction using predictive Model...

Force Feedback / Vibration
Hello, I bought a steering wheel for racing games some time ago (a SpeedLink Darkfire). Works great in wine, but no vibration. Actually it works if I use fftest. Just not in wine. I use Ubuntu 11.04, wine 1.3.28 (which is the most recent development version right now). The wheel is connected by USB. Wine also says something about it: Code: fixme:dinput:JoystickWImpl_SendForceFeedbackCommand No direct actuator control in...

To owners of xbox360 joysticks..
I'm looking for people who have an xbox360 joystick to help run some tests so I can get information on implementing xinput for wine. The more 360 joysticks plugged in the better. Can you please go to the forum post I made and test: http://forum.freegamedev.net/index.php?t=msg&th=1980&start=0 Thanks, Andrew

Replacement disks for Sun X4500
I am bumping this thread because I too have the same question ... can I put modern 3TB disks (hitachi deskstars) into an old x4500 ? If not, would the x4540 accept them ? -- This message posted from opensolaris.org

high density SAS
Well Solaris SAS isn''t there yet but anyway just found some interesting high density SAS/SATA enclosures. <http://xtore.com/product_list.asp?cat=JBOD> The XJ 2000 is like the x4500 in that it holds 48 drives, however with the XJ 2000 2 drives are on each carrier and you can get to them from the front. I don''t like xtore in general but the 24 bay (2.5" SAS) and 48

To begin with below is the transactional data format that i want prepare: Pump-id| Timestamp | temp | vibration | suction pressure| discharge pressure | Flow Above transactional data has to be prepared with below failure modes Defects : (1) Cavitation ? very high in frequency but low impact (2) Bearing Damage ? very low in frequency but high impact (3) Worn Shaft ? medium frequency but medium impa...

Hz vs bitrate?
the Vorbis FAQ says: "mid to high quality (8kHz-48.0kHz, 16+ bit, polyphonic) audio and music at fixed and variable bitrates from 16 to 128 kbps/channel." What is the difference between Hz and bitrate? Doesn't MP3 support higher bitrates? Pointers for more reading are welcome.

...cess to the machine, and you can afford the downtime to shut it down, open up the chassis and re-seat the drive and cables. Every now and then I have PCIe cards that work fine for years, then suddenly disappear after a reboot. I re-seat them and they go back to being fine for years. So I believe vibration does sometimes play a role in mysterious problems that creep up from time to time.

Gamepad Support
Hello, I have a big problem: I recently bought a gamepad (Speedlink) which is perfectly supported by Mafia - The city of Lost Heaven. But now, I tried it with several other games (18 wheels of steel, Farming Simulator 2011), but it is not recognized. Farming Sim 2011 doesn't recognize any button or axis pressed. 18 WoS - Pedal to the metal does recognize the gamepad itself (even twice), but

Fourier Transform with irregularly spaced x
Dear all, I work with (vibrational) spectra: some kind of intensity (I) over frequency (nu), wavelength or the like. I want to do fourier transform for interpolation, smoothing, etc. My problem is that the spectra are often irregularly spaced in nu: the difference between 2 neighbouring nu varies across the spectrum, and data...

Centos machine sometimes unreachable
I have a simple perl script that every few hours pings the handful of machines on my LAN. Lately I've sometimes been getting ping of 192.168.0.1 succeeded ping of 192.168.0.7 succeeded ping of 192.168.0.5 FAILED ping of 192.168.0.6 succeeded ping of 192.168.0.9 succeeded This machine in question has been running Centos faithfully for about six years and no recent changes to it have been

Re: An introduction to compressed audio with Vorbis
...irly fine-grained - it ranges from -32,768 (complete silence during that snapshot) to 32,767 (the loudest volume measurable)." That's not correct. A single sample is not meaningful by itself; each sample merely represents a voltage. It's the *difference* between samples that creates vibrations in a speaker, and therefore sound waves. Pure digital silence is a set of samples whose value is consistently zero (not -32768). A "pure" tone is produced by samples whose values conform to a sine function -- a "sine wave". The frequency of the sine wave (i.e., how quickly t...

Re: Hot swap CPU -- shared memory (1 NUMA/UPA) v. clustered (4 MCH)
...SAS. Parallel is dead, because it's much better to have a number of point-to-point devices with direct pins to a PHY to a wide ASIC than a wide bus that is shared by all devices. And these 10K RPM SATA models are rolling of the _exact_same_ fab lines as their SCSI equivalents, with the same vibration specs and MTBF numbers. They are not "commodity" [S]ATA drives, of which many 7,200rpm SCSI drives are even now sharing (and share the same 0.4Mhr MTBF as commodity [S]ATA). -- Bryan J. Smith mailto:b.j.smith at ieee.org

alternative FXO gateway to Mediatrix 1204?
I bought a couple of Mediatrix 1204's a few of months back. (Perceived advantages were relatively low overall cost and size per port, and it isn't nearly as vibration sensitive as a PC would be.) Rich Adamson's review from Feb 1 is comprehensive, and the only thing I'd like to add is this: One "feature" of these units that absolutely infuriates me is its behavior for an incoming PSTN call: 1) upon sensing an incoming PSTN call, it goes off-h...
