Fano Sequential Decoding is a technique for communicating at a high information rate and with a high reliability over a large class of channels. However, equipment cost and variation in the time required to decode successive transmitted digits limit its use. This work is concerned with the latter limitation. Others have shown that the average processing time per decoded digit is small if the in...

The operational cycle of a storm water quality control basin can be divided into the waiting period between events and the filling and draining period during an event. In this study, an inherent overflow risk is defined as the probability of having a large event exceed the basin storage capacity. Such a probability is prescribed by the basin storage capacity and the local distribution of rainfa...

Software testing is an integral part of modern software engineering practice. Past research has not only underlined its significance, but also revealed multi-faceted nature. The practice and adoption influenced by many factors that go beyond tools or technology. This paper sets out to investigate the context from practitioners’ point view mining analyzing sentimental posts on widely used questi...

Conditions are provided to conclude an error bound for truncations and perturbations of Markov decision problems. Both the average and finite horizon case are covered. The results are illustrated by a truncation of a Jacksonian queueing network with overflow control. An explicit error bound for this example is obtained. Key-words Markov Decision Problems * Truncation * Perturbation * Error Boun...

Buffer overflows still remain a problem for software today. Even with address space randomization and non-executable stacks software remains vulnerable to clever exploits. In this paper we introduce the buffer overflow through a pratical example and take a retrospective look on the past 25 years of the arms race on buffer overflow exploits and protections.

Using both in vitro (hippocampal synaptosomes in superfusion) and in vivo (microdialysis) approaches we investigated whether and to what extent β amyloid peptide 1-40 (Aβ 1-40) interferes with the cholinergic modulation of the release of glycine (GLY) in the rat hippocampus. The nicotine-evoked overflow of endogenous GLY in hippocampal synaptosomes in superfusion was significantly inhibited by ...

We consider a fluid queue fed by a superposition of n homogeneous on-off sources with generally distributed onand off-periods. We scale buffer space B and link rate C by n, such that we get nb and nc, respectively. Then we let n grow large. In this regime, the overflow probability decays exponentially in the number of sources n; we specifically examine the situation in which also b is large. We...

BACKGROUND Endothelin (ET)-1 and norepinephrine (NE) are involved in myocardial ischemia/reperfusion injury. We investigated the role of ET-1 in ischemia/reperfusion-induced NE overflow and cardiac dysfunction using a selective ET(A) receptor antagonist (ABT-627), a selective ET(B) receptor antagonist (A-192621), and the spotting lethal (sl) rat, which carries a naturally occurring deletion in ...
