...c "sext i32 undef to > i64", and thus also undef? No; sext i32 undef to i64 returns an extraordinary thing. It's a 64-bit value where the low 32 bits are undef, and the high 32 bits are sign extension from whatever bit 31 happened to be. And the low 32 bits in this new value also fluctuate, and the high 31 bits in this value fluctuate with them in concert with bit 31 of the new value. FWIW, you can also get non-bitwise fluctuation, such as (undef*3), which is a value which fluctuates around multiples of 3. Or (undef*3)/5+1, which fluctuates around, well, any value which could be co...

Dear R-users, Has anyone written a function for multifractal detrended fluctuation analysis? The "fractal" package does mono-fractal DFA, but not multifractal as far as I can tell. The MF-DFA approach is presented in: J. W. Kantelhardt, S. Zschiegner, E. Koscielny-Bunde, S. Havlin, A. Bunde, and H. E. Stanley, "Multifractal Detrended Fluctuation Analysi...

...I tried nut 2.0.5 (which came with 2007.1) but it wouldn't work, and then research showed it was an older version of nut. So nut-2.2.1-2 src rpm was pulled from Mandriva 2008.1, the binary rpm built, and nut and nut-server installed from that binary rpm. It mostly works, but the UPS status is fluctuating between B and L. With /etc/ups/ups.conf set like this: [myserverups] driver = usbhid-ups port = auto desc = "TrippLite SU 1500RTXL2Ua" and some entries in upsmon.conf and nut was started with: service upsd start service upsmon start it seemed to start up ok. upsc show...

I'm working with the DFA (detrended fluctuation analysis) function in the package fractal on postural sway data, and for the life of me can't get the results to turn out as they should given what my data looks like. The data resemble a random walk, but the Hurst exponent estimates that I'm getting at ~0.9 instead of ~1.4, which is...

Hi - Suppose I have a Q-1 Vorbis stream being served from a machine on a low-bandwidth internet connection. I listen to the stream locally using Winamp, which shows the bitrate fluctuating between around 35-55 kbps, the average being 48k. Now suppose I have 10 external listeners connected. How much bandwidth will they need/use? Common sense says: average bitrate * 10 = 480kbps (plus any overheads) Here's the question: If I have 10 listeners connected, and the bitrate fluct...

Good afternoon, my name is Gorka Merino and i am a scientist working in the Marine Science Institune in Barcelone. I'm interested in the application of "Detrended Fluctuation Analysis" (DFA) with the R packages. I've tried to obtain some information related to DFA from the 'Help' options but failed. Could somebody inform me about the use of these techniques in R language? Thank you very much. Gorka Merino Gorka Merino Institut de Ci?ncies del Ma...

Hi all, Has anyone tested for FA in R? I need to seperate out the variance due to measurement error from variation between individuals (following Palmer & Strobeck 1986).

Those ordered extents whose csum was being calculated didn''t belong to the current fsync, we can ignore them. By this patch, the performance fluctuating doesn''t happen, and the average performance grows up by ~2%.

Unless your code changes algorithm, you don't need to worry too much about performance fluctuations caused by that change. This may vary on compiler, compiler version, code around your change, and test cases. -------------- next part -------------- An HTML attachment was scrubbed...

Dear useRs, the strucchange package for testing for structural change has been updated: the current version is 1.2-4. The most significant additions were two functions gefp() and efpFunctional(). gefp() implements a class of generalized M-fluctuation tests for testing for parameter instability or structural change in general parametric models including generalized linear models (GLMs). efpFunctional() provides infrastructure for inference based on functionals applied to empirical fluctuation processes such as automatic tabulation of critic...

Hi All I was using the DFA() in the fractal package to examine a set of time series data. And I was not sure what the H estimate meant from the summary table. is it the alpha of the power law equation?

...r variables. I am using the cv.glmnet function to do 10-fold cross validation on a sequence of lambda values which I let glmnet determine. I then take the optimal lambda value (lambda.1se) which I then use to predict on an independent cohort. What I am finding is that this optimal lambda value fluctuates everytime I run glmnet with LASSO. It deviates quite a bit such that each time I generate an ROC curve for my validation cohort, I get AUC values which deviate a bit. Does anyone know why there is such a fluctuation in the generation of an optimal lambda? I am thinking it might be due to the 1...

hi all we're using rsync to backup our web server at the moment using it in a cron job the server we are using to receive all the sync files is a live but not heavily used linux machine but rsync still takes up more resources than we want it to it takes up to 95% (fluctuating) cpu load and a fair bit of memory too the cron job uses nice -19 rsync but that doesn't seem to do anything, is there anyway to make it use like 5% cpu or something? thanks dave

...CREF here, but it may actually still be "<ty> addrspace(k)*" where k is specially noted in the datalayout. Semantics: 1. GCREF represents an equivalence class of values (equivalence relation being "points to a fixed semantic object"). The bitwise representation fluctuates constantly outside the compiler's control (the dual of `undef`), but may have invariants (in particular, we'd like to be able to specify alignment, nonnull etc.). At any given point in time all GCREF instances pointing to the same object have the same bitwise representati...

The thing is that many UPS models will report "on battery" when the voltage fluctuates out of range, but a switching power supply might still be able to coast through it-- especially if the supply is oversized for the load at the time of the abnormality. Since both "outages" (really, the on-battery states) were exactly 10 seconds long means that the UPS was probably tryi...
