Several weeks ago, we posted a message seeking information about time sources.? There were many helpful and educational responses. An excerpt from one of the responses is included below.? We have been following up with regard to how SDR capabilities might be used for obtaining time using SDR dongles as well as using the time source product referenced in that response. Our SDR investigation has

Hi everyone, I was trying to mode the following exercise using R. The question: Set up a one pool model using numericintegration. The model will run from time 1 to time 30 using a time step of 1.The pool (A) will be fed by flux "inA" at a rate of 5 units per hour anddrained by flux "outA" at a rate of 20% per hour. At time 0, A has 5units. At time 30, what is the pool size of

  Hi there,   I am beginner in R and I have some basic question. Suppose I run a common procedure such as a t test or cox model like below:   out<-coxph( Surv(tstart,tstop, death1) ~ x1+x1:log(tstop+1) , test1,method=c("breslow"))    Which yields the following result:   Call: coxph(formula = Surv(tstart, tstop, death1) ~ x1 + x1:log(tstop +     1), data = test1, method =

I have data that looks like this time_stamp (seconds) user_id The data is (partial) ordered by time - in that sometimes transactions occur at the same timestamp. The output I want is collated by transaction time on a per user basis, normalized by the maximum number of transactions per user, and aggregated over each day. So, if the users have 50 transactions in the first day and 20 transactions

I gave myself a toy, one of those cheap USB Software Define Radios, and would like to use it on my C7 box. Having wasted some time on it, I gave up and installed Ubuntu on a USB HD so I can boot that to play with SDR. The Ubuntu GQRX installation is well documented and went off without a hitch. but I just hate having to boot something else on my main box (partly because it also runs a mailserver

I've been monitoring CPU temperature on a few Dell SC1435s running CentOS4 via OpenIPMI and 'ipmitool sdr'. It's been working very nicely, but the upgrade to 4.5 not so long ago seems to have broken something: # ipmitool sdr type Temperature Temp | 01h | ns | 3.1 | Disabled Planar Temp | 04h | ok | 7.1 | 30 degrees C Temp Interface | 53h | ns | 7.1

Hi there, I have a rather large data set and perform the following cox model: test1 <- list(tstart,tstop,death1,chemo1,radio1,horm1) out1<-coxph( Surv(tstart,tstop, death1) ~ chemo1+chemo1:log(tstop+1)+horm1+horm1:log(tstop+1)+age1+grade1+grade1:log(tstop+1)+positive1+positive1:log(tstop+1)+size1+size1:log(tstop+1), test1) out1 Up to here everything works fine (with each covariate

Hi, While doing Linux kernel builds linked with lld, I've tracked down a difference that breaks relocation of the kernel image (e.g. under KASLR[1]). Some relocations are changed to ABS (weirdly, all are in .rodata section). Note the difference below in the resulting linked output. .L__const._start.instance becomes *ABS* only under lld: $ cat minimal.c struct minimal { void *pointer;

Hello, I have a cohort with approx 1,200 patients at the ages of 30-65 that had their first myocardial infarction during 1992: · They were in a follow up until 2005. · About 400 of them died during this period of time (right censored) · Each one of them had up to 4 mi recurrent events. I am using the semi-parametric model in order to assess the relationship of

Dear list, we have a relatively new Sun Storage 7310, where we connect CentOS 5.5 Servers (IBM LS21/LS41 Blades) via Brocade Switches, 4GBit FC. The Blades boot from SAN via qla2xxx, and have no harddisks at all. We want them to use multipathing from the very beginning, so /boot and / are already seen by multipathd. Problem is, that the Sun 7310 has two storage heads which run in

Hi. While submitting SDR-0149 on ZFS bug I encountered problem with format utility. This is v240 with snv_29 with internal disks. On s0 slices there is zfs pool (which is not imported). I did unload zfs modules then moved zfs driver and run format. Now format quits just because there''s no zfs module (and not even one zfs pool is imported). It shouldn''t behave that

Hi All, As I've said before, Opus is excellent. I use it to reduce network load when running a remote radio, the encoding improvements in 1.1 are very impressive. I downloaded and compiled 1.1 (VS2010) but can't find the 1.1 API changes - maybe I'm just being extra-thick this morning J . Simon GD4ELI/HB9DRV http://v2.sdr-radio.com/ -------------- next part

Hi Team, I have written below code to get the VM state at run time. I found, though the VM is in shut-off state, when I use the function virDomainGetInfo(); I get state as running. Could you please let me know what wrong I am doing. To know the actual VM state I used 'virsh list' and it clearly shows the VM is in shut-off state. Please find the log and code snippet below. Log from virsh:
