Matrix multiplication
Hi, I have a transition matrix T for which I want to find the steady state matrix for. This could be approximated by taking T^n , for large n. T= [ 0.8797 0.0382 0.0527 0.0008 0.0212 0.8002 0.0041 0.0143 0.0981 0.0273 0.8802 0.0527 0.0010 0.1343 0.0630 0.9322] According to a text book I have T^200 should have reached the steady state L L

AUC steady state calculations
Hi, a collegue has send me an excel sheet with some plasma values, and now he wants to know the AUC steady state. I took a look at the CRAN taskviews, and came up with PK, PKtools, ... The AUC calculation, no problem with that, but how do I calculate the steady state? One way of thinking was with the aid of multiple t-test, to find where we couldn't find difference between the different

alternative to multiple t-test to find steady-state
Hi, My collegue has asked me to calculate the steady state of a pharmacokinetic study. This is defined as where the concentration after a certain time doesn't increase anymore. So if I perform multiple t-tests between the sample points, with alternative less, then I can see which from which time point there isn't an increase in concentration. But this doesn't feel good to me. I

trouble with installing pbatR
Hello folks, I am having a problem installing pbatR package. (My R version is 2.8.1.) As I execute a command > install.packages(lib='/usr/local/apps/R-2.8.1/lib64/R/library', "pbatR") it detects lack of rootSolve package and attempts to install it. But cannot seem to compile it, and the rest is aborted. Any hint as to what I can do? Thank you in advance for your

SMB throughput inquiry, Jeremy, and James' bow tie
I went to the site to subscribe again and ended up watching some of Jeremy's Google interviews. I particularly enjoyed the interview with James and the bow tie lesson at the end. :) So anyway, I recently upgraded my home network to end-to-end GbE. My clients are Windows XP SP3 w/hot fixes, and my Samba server is 3.5.6 atop vanilla kernel.org Linux 3.2.6 and Debian 6.0.6. With FDX fast

busy lamp filed
Hi, Previously i was using asterisk 1.4 with freepbx installation. To try the 1.6 version i installd anc configured everything.. Just one thing didnt work so far.. I am using grandstream 2000 and it has a line busy indicator for chef secretary phones. But now, this feature does not work. I can see the line is online..with a green steady light.. But when the line is busy or DND, it wont change to

Noise Cancellation of Server Noise
Has anyone come across a device that could cancel out the noise from servers, ie. the fan noise? I have a server rack near my office and would like to see if i can decrease the noise level. It would seem to me that the steady drone of the fans could be cancelled out to a large extent.

Infrequent but steady NULL-pointer caused segfault in as.POSIXlt.POSIXct (R 3.4.4)
In an optimized build, debug info is just an approximation. It might help to debug in a build of R and packages without compiler optimizations (-O0), where the debug information is accurate. However, first I would try to modify the example to trigger more often, or try to find external ways to make it trigger more often (e.g. via gctorture). Then I would try to make the example smaller (not

[LLVMdev] Proposal for a Google summer of code project for the Java frontend.
I would prefer to see actual code to make safe schedules. With code I can see what changes one must make. I can also show in detail these changes, which would give security to the LLVM project that the proposal is viable. By contrast, without code, neither me nor LLVM project can ensure that the project will be successfully performed behind schedule. Since this is a difficult project (we are

Problems with TDBs on CTDB-managed Samba instance
Hi Jeremy, Thanks so much for your reply! As a matter of fact, we did just that around 3:45p yesterday when our CTDB cluster was unable to self-heal from the latest in this series of failover events. Here's how the situation went down: 1) We saw flapping identical to that described in my original post 2) After about 30 minutes of waiting, CTDB was just spinning with `smbd` repeatedly

Xen time drift issues
Hello everyone! I been observing some peculiar time drift on my Xen domains (dom0 and domUs). The time (as returned by timeofday) on my domains drifts at an almost steady rate from the real time ( as read from the time stamp counter ). The drift is so constant that it makes me think there should be some simple explanation for it in the way Xen keeps time. Some info about my set up: guest OS:

current zfs tuning in RELENG_7 (AMD64) suggestions ?
I gave the AMD64 version of 7.2 RC2 a spin and all installed as expected off the dvd INTEL S3200SHV MB, Core2Duo, 4G of RAM In the past it had been suggested that for zfs tuning, something like vm.kmem_size_max="1073741824" vm.kmem_size="1073741824" vfs.zfs.prefetch_disable=1 However doing a simple test with bonnie and dd, there does not seem to be very much difference in

[llvm-mca] What's the difference between Rthroughput and "total cycles" in llvm-mca
What is the difference between the two? I thought "Rthroughput" is basically the number of cycles required to execute a single iteration at steady state, but this does not seem to match with the schedule/timeline generated by llvm-mca.

Infrequent but steady NULL-pointer caused segfault in as.POSIXlt.POSIXct (R 3.4.4)
A reply from stackoverflow suggests I might have hit this bug: https://sourceware.org/bugzilla/show_bug.cgi?id=14023 I can confirm that this glibc bug affects my system (latest CentOS 7). However, as far as I know, R is not multithreaded in its core. Is it possible that some library triggered this? Regards, Steve Tomas Kalibera <tomas.kalibera at gmail.com> ?2019?8?2??? ??4:59??? >

Physical or Statistical Explanation for the "Funnel" Plot?
The R code below produces (after running for a few minutes on a decent computer) the plot shown at the following location: http://n2.nabble.com/Is-there-a-physical-and-quantitative-explanation-for-this-plot--td2542321.html I'm just taking the mean of a given set of random variables, where the set size is increased. There appears to be a quick convergence and then a pretty steady variance
