We characterize a TCP implementation by a function, called a pro le, that expresses the instantaneous throughput at the source in terms of the instantaneous roundtrip time and instantaneous loss rate for bulk transfers. We empirically obtain pro les of several TCP implementations, accurately enough to distinguish not only the TCP version but also the implementation (BSD, Windows, etc). Pro les ...

This paper gives a literature review of detection theory and information theory in the Poisson regime, where the channel model is a Poisson point process whose instantaneous rate is controlled by the input. I. Communication under the Poisson Regime In the semi-classical model of photodetection, the output of the photodetector (e.g. a p-i-n diode) is the superposition of two independent Poisson ...

In this paper, a new method for characterizing the newborn heart rate variability (HRV) is proposed. The central of the method is the newly proposed technique for instantaneous frequency (IF) estimation specifically designed for nonstationary multicomponent signals such as HRV. The new method attempts to characterize the newborn HRV using features extracted from the time–frequency (TF) domain o...

Auditory pattern recognition by the CNS is a fundamental process in acoustic communication. Because crickets communicate with stereotyped patterns of constant frequency syllables, they are established models to investigate the neuronal mechanisms of auditory pattern recognition. Here we provide evidence that for the neural processing of amplitude-modulated sounds, the instantaneous spike rate r...

background: presently, the british-american tobacco company (bat) located in ibadan, oyo state is the only tobacco producing company in nigeria accounting for about nine different brands of cigarette tobacco smoked in the country. the tobacco leaves are produced from some farmlands located in oke-ogun area of ibadan where special fertilizers are used for the growing of the tobacco leaves. the u...
