OBJECTIVE
Only the simultaneous analysis of periodic and nonlinear properties of heart rate fluctuations (HRF) can describe completely this complex physiological process. Up to now there is, apart… (More)
The computation power of PC clusters running the Linux operating system rivals that of supercomputers of just a few years ago at a fraction of the purchase price. However, the lack of good… (More)

To evaluate whether or not heart-rate variations (HRV) have both periodic and deterministic-chaotic properties in conscious and anaesthetized states, HRV of 9 rabbits were analysed by power spectral… (More)

In adult conscious rabbits, the respiratory frequency (RF) is almost always higher than half the heart rate (HR) Thus, no "classical" respiratory sinus arrhythmia occurred. But now, slow HR… (More)

We discuss our findings on how well the Linux 2.4 and 2.5 TCPIP stack scales with multiple network interfaces and with the SMP network workloads on 100/1000 Mb Ethernet networks. We identify three… (More)
