Analysis of software fault removal policies using a non-homogeneous continuous time markov

by Swapna S. Gokhale
"... Abstract. Software reliability is an important metric that quantifies the quality of a software product and is inversely related to the residual number of faults in the system. Fault removal is a critical process in achieving desired level of quality before software deployment in the field. Conventi ..."

continuous time Markov chain. The fault removal rate is initially assumed to be constant, and it is subsequently extended to cover time and state dependencies. We then extend the non-homogeneous continuous time Markov chain (NHCTMC) framework to include imperfections in the fault removal process. A method

Supply Disruptions with Time-Dependent Parameters. Forthcoming

by Andrew M. Ross, Ying Rong, Lawrence V. Snyder - in Computers and Operations Research , 2006
"... We consider a firm that faces random demand and receives product from a single supplier who faces random supply. The supplier’s availability may be affected by events such as storms, strikes, machine breakdowns, and congestion due to orders from its other customers. In our model, we consider a dynam ..."

dynamic environment: the probability of disruption, as well as the demand intensity, can be time dependent. We model this problem as a two-dimensional non-homogeneous continuous-time Markov chain (CTMC), which we solve numerically to obtain the total cost under various ordering policies. We propose

Real-time american sign language recognition using desk and wearable computer based video

by Thad Starner, Joshua Weaver, Alex Pentland - IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE , 1998
"... We present two real-time hidden Markov model-based systems for recognizing sentence-level continuous American Sign Language (ASL) using a single camera to track the user’s unadorned hands. The first system observes the user from a desk mounted camera and achieves 92 percent word accuracy. The secon ..."

An Analytical Model for a Book-ahead Bandwidth Scheduler

by Xiangfei Zhu, Mark E. Mcginley, Tao Li, Malathi Veeraraghavan
"... Abstract — Optical networks with book-ahead bandwidth schedulers are being deployed to meet the high-speed and predictable-service networking requirements of applications in the scientific research community. We present an analytical model for a single-link book-ahead bandwidth scheduler, which resp ..."

responds to advance reservation requests with the first-available time interval in which a channel is available. The link is assumed to be divided into m channels, and time is discretized into intervals. Our proposed model is a non-homogeneous continuous-time Markov chain, which has an embedded discrete-time

Non-Uniform Random Variate Generation

by Luc Devroye , 1986
"... This is a survey of the main methods in non-uniform random variate generation, and highlights recent research on the subject. Classical paradigms such as inversion, rejection, guide tables, and transformations are reviewed. We provide information on the expected time complexity of various algorith ..."

Metabolic stability and epigenesis in randomly connected nets

by S. A. Kauffman - Journal of Theoretical Biology , 1969
"... “The world is either the effect of cause or chance. If the latter, it is a world for all that, that is to say, it is a regular and beautiful structure.” Marcus Aurelius Proto-organisms probably were randomly aggregated nets of chemical reactions. The hypothesis that contemporary organisms are also r ..."

A simple method for displaying the hydropathic character of a protein

by Jack Kyte, Russell, F. Doolittle - Journal of Molecular Biology , 1982
"... A computer program that progressively evaluates the hydrophilicity and hydrophobicity of a protein along its amino acid sequence has been devised. For this purpose, a hydropathy scale has been composed wherein the hydrophilic and hydrophobic properties of each of the 20 amino acid side-chains is tak ..."

When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved

Model-checking algorithms for continuous-time Markov chains

by Christel Baier, Boudewijn Haverkort, Holger Hermanns, Joost-Pieter Katoen - IEEE TRANSACTIONS ON SOFTWARE ENGINEERING , 2003
"... Continuous-time Markov chains (CTMCs) have been widely used to determine system performance and dependability characteristics. Their analysis most often concerns the computation of steady-state and transient-state probabilities. This paper introduces a branching temporal logic for expressing real-t ..."

"... WinBUGS is a fully extensible modular framework for constructing and analysing Bayesian full probability models. Models may be specified either textually via the BUGS language or pictorially using a graphical interface called DoodleBUGS. WinBUGS processes the model specification and constructs an ob ..."

The software offers a user-interface, based on dialogue boxes and menu commands, through which the model may then be analysed using Markov chain Monte Carlo techniques. In this paper we discuss how and why various modern computing concepts, such as object
