The authors present a theory of stochastic interactive parallel processing with special emphasis on channel interactions and their relation to system capacity. The approach is based both on linear systems theory augmented with stochastic elements and decisional operators and on a metatheory of parallel channels' dependencies that incorporates standard independent and coactive parallel models as...

We propose an accelerated CTMC simulation method that is exact in the sense that it produces all of the transitions involved. We call our method Path Sampling Simulation as it samples from the distribution of trajectories and the distribution of time given some particular trajectory. Sampling from the trajectory space rather than the transition space means that we need to generate fewer random ...

We develop a Bayesian model for decision-making under time pressure with endogenous information acquisition. In our model, the decision-maker decides when to observe (costly) information by sampling an underlying continuoustime stochastic process (time series) that conveys information about the potential occurrence/non-occurrence of an adverse event which will terminate the decisionmaking proce...

We study the time reversal of a general Piecewise Deterministic Markov Process (PDMP). The time reversed process is defined as X(T−t)−, where T is some given time and Xt is a stationary PDMP. We obtain the parameters of the reversed process, like the jump intensity and the jump measure.

Online scheduling (also known as dynamic scheduling) refers to the real-time coordination of operation processing while new operations are continuously arriving. The objective of this paper is the study of different online scheduling techniques in a dynamic, stochastic job shop scheduling environment. We present a quantitative study of the quality of dispatching and optimizing scheduling techni...

 Background and Objectives:Rapid processing of histopathological specimens and decreased turnaround time is important to fulfill the needs of clinicians treating sick patients, so the present study was conducted to compare the time taken and quality of sections in processing of prostatic tissue by rapid microwave and conventional techniques using morphometry. Methods: Four to five mm thick p...

In this paper, we consider the stochastic profile scheduling problem of a partially ordered set of tasks on uniform processors. The set of available processors varies in time. The running times of the tasks are independent random variables with exponential distributions. We obtain a sufficient condition under which a list policy stochastically minimizes the makespan within the class of preempti...

On the future infimum of positive self-similar Markov processes. Abstract We establish integral tests and laws of the iterated logarithm for the upper envelope of the future infimum of positive self-similar Markov processes and for increasing self-similar Markov processes at 0 and +∞. Our proofs are based on the Lamperti representation and time reversal arguments due to Chaumont and Pardo [9]. ...

Improvements in the performance of end-computers and networks have recently made the construction of a grid system over the Internet feasible. A grid environment comprises many computers, each having a set of components and distinct performance, that are shared among many users and managed in a distributed manner. Thus, it is important to focus on a situation in which the computers are used une...

The problem of detecting changes in the statistical properties of a stochastic system and time series arises in various branches of science and engineering. It has a wide spectrum of important applications ranging from machine monitoring to biomedical signal processing. In all of these applications the observations being monitored undergo a change in distribution in response to a change or anom...
