the aim of this article is to review the application of current imaging techniques used for the detection of viable myocardium. each technique is discussed briefly, and the more commonly used techniques are compared. the imaging techniques reviewed herein are dobutamine stress echocardiography, single photon emission tomography, magnetic resonance imaging, positron emission tomography with f-18...

We study strategic capacity planning in the semiconductor industry. Working with a major US semiconductor manufacturer on the strategic configuration of their worldwide production capacities, we identify two unique characteristics of this problem as follows: (1) wafer demands and manufacturing capacity are both main sources of uncertainty, and (2) capacity planning must consider two distinct vi...

Foreign direct investment (FDI) is assumed to be a source of knowledge flows across National Innovation Systems, with particular relevance for developing countries. Nonetheless, empirical assessments are usually manufacturing-oriented, providing only a partial view of the phenomena under scrutiny. This article aims at contributing to this body of literature by investigating the impacts of inwar...

this paper is a state-of-the-art in sulphur-asphalt (sa) design technology based on a comprehensive analysis of current practice and technical literature, in order to investigate the possible use of sa pavements in iran. in this paper, the major aspects(material, technology, properties, production, placement, quality assurance, design, and field varification) of sa pavements are considered. fer...

Despite the fact that representation is at the center of AI and cognitive science, there is still no consensual model of what representation, thus cognition, is. I argue that there are good reasons for this impasse: none of the approaches to modeling representation that are currently on offer is ultimately viable. I outline several of the deepest reasons for this conclusion, and offer an altern...

Elaborating an appropriate cellular manufacturing system (CMS) could solve many structural and operational issues. Thereby, considering some significant factors as worker skill, machine hardness, and product quality levels could assist the companies in current competitive environment. This paper proposes a novel interactive possibilistic mixed integer nonlinear approach to minimize the total co...

We describe a new version of the Queueing Network Analyzer (QNA) software package that was developed especially to analyze manufacturing lines. The goal was to obtain a convenient tool for estimating capacity, work-in-process inventory and production intervals, as needed to design or change a manufacturing line. QNA is an analytic tool, based on mathematical formulas rather than simulation, and...
