...lue 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 computed by that expression. You can build arbitrarily complex expression trees around undef, and everything fluctuates according to the constraints...

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 Analysis o...

I am trying to get a TrippLite SU1500RTXL2Ua working with nut on Mandriva 2007.1, is there a particular version of nut needed to get this to work? At first 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

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 the...

...onnected. 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 fluctuates up to 55kbps, then is the actual bandwidth requirement at that instant 550kbps? Or are the fluctuations more rapid than I can appreciate from the Winamp display? Or to put it another way, over what period of time is the average bitrate calculated, and is this period significant in terms of average buffer size? Also just quickly - could the external authentication mechanism be used to reject ne...

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 Mar,...

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).

In order to improve the performance of fsync, we use the outstanding ordered extents to avoid looking up the checksum from the csum tree. But we didn''t filter out the ordered extents whose csum is still being calculated, when we got those ordered extents, we had to wait for the csum calculation. It made the performance dropped down suddenly. (On my box, it drop down from 56MB/s to

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 critical...

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?

...t 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 10 fold cross validation step the training set is not being split well know to have enough alive and dead cases?

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,

This is a proposal to add strong GC reference types to LLVM. We have some local (downstream) patches that are needed to prevent LLVM's optimizer from making transforms that are problematic in the presence of a precise relocating GC. Adding a notion of a strong GC reference to LLVM will let us upstream these patches in a principled manner, and will act as a measure to avoid new problematic

...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 trying to "debounce" the voltage fluctuation by not switching back to line power immediately after the voltage went back to normal. For APCs and MGEs, I think it is typically 5 seconds. Several people have rigged up longer timers with upssched to not send the wall message until it has been on battery for, say, a full minute.
