The re-entrant flow shop scheduling problem (RFSP) is regarded as a NP-hard problem and attracted the attention of both researchers and industry. Current approach attempts to minimize the makespan of RFSP without considering the interdependency between the resource constraints and the re-entrant probability. This paper proposed Multi-level genetic algorithm (GA) by including the co-related reen...

Re-entrant modulation of visual cortex has been suggested as a critical process for enhancing perception of emotionally arousing visual stimuli. This study explores how the time information inherent in large-scale electrocortical measures can be used to examine the functional relationships among the structures involved in emotional perception. Granger causality analysis was conducted on steady-...

Energy-corrected finite element methods provide an attractive technique to deal with elliptic problems in domains with re-entrant corners. Optimal convergence rates in weighted L2-norms can be fully recovered by a local modification of the stiffness matrix at the re-entrant corner, and no pollution effect occurs. Although the existence of optimal correction factors is established, it remains op...

This paper studies the exertion of market power in large buyer groups confronting an incumbent monopolist and a potential market entrant in a repeated trade situation. In the experiment, buyer power can either occur as demand withholding when only the incumbent is present in the market, or it can take the form of buying at higher prices from the entrant in order to foster future re-entry. Compa...

Much of our understanding of the mechanisms of macro re-entrant atrial tachycardia comes from study of cavotricuspid isthmus (CTI) dependent atrial flutter. In the majority of cases, the diagnosis can be made from simple analysis of the surface ECG. Endocardial mapping during tachycardia allows confirmation of the macro re-entrant circuit within the right atrium while, at the same time, permitt...

1. Our group has developed finite element models of ventricular anatomy that incorporate detailed structural information. These have been used to study normal electrical activation and re-entrant arrhythmia. 2. A model based on the actual three-dimensional microstructure of a transmural left ventricular (LV) segment predicts that cleavage planes between muscle layers may give rise to non-unifor...

This paper presents the development of an alternative method for makespan computation algorithms of a re-entrant flow shop scheduling problem using bottleneck analysis. The computation is specifically intended for the cyber manufacturing centre (CMC) which is an Internet based collaborative design and manufacturing services at Universiti Tun Hussein Onn Malaysia. The CMC processes scheduling re...

-There has been a lot of research about scheduling manufacturing systems with dispatching rules in the past. However, most studies concentrate on simplified scenarios considering only one type of resource, usually machines. In this study dispatching rules are applied to a more realistic scenario, which is dual constrained by machines and operators and has a re-entrant process flow. Interdepende...

A fast algorithm for computing the solvent-accessible molecular surface area (SAS) using Boolean masks [Le Grand,S.M. and Merz,K.M.J. (1993). J. Comput. Chem., 14, 349-352) has been modified to estimate the solvent-excluded molecular surface area (SES), including contact, toroidal and re-entrant surface components. Numerical estimates of arc lengths of intersecting atomic SAS are used to estima...

This paper focuses on a two-machine re-entrant flowshop scheduling problem with the objective of minimizing makespan. In the re-entrant flowshop considered here, all jobs must be processed twice on each machine, that is, each job should be processed on machine 1, machine 2 and then machine 1 and machine 2. We develop dominance properties, lower bounds and heuristic algorithms for the problem, a...
