ware design and development, technical publishing, and advanced office applications. Integrated circuits, mechanical assemblies, computer programs, complex technical documents, and business reports and presentations are today being more efficiently and effectively designed and developed by professionals using dedicated computer workstations. Graphics is so integral to these workstations and app...

In recent years a number of load sharing (LS) mechanisms have been proposed or implemented to fully utilize system resources. We have designed and implemented a decentralized real-time LS mechanism based on the Condor package 17, 18]. Two important features of our design are use of region-change broadcasts in the information policy to provide each workstation with timely state information at mi...

OBJECTIVES Work-related musculoskeletal disorders in the neck and shoulder regions are common among carpet weavers. Working for prolonged hours in a static and awkward posture could result in an increased muscle activity and may lead to musculoskeletal disorders. Ergonomic workstation improvements can reduce muscle fatigue and the risk of musculoskeletal disorders. MATERIAL AND METHODS The ai...

The Computer Systems Laboratory has been involved in a VLSI research program for one and a half years. The major areas under investigation have included: analysis and synthesis design aids, applications of VLSI to computer graphics, !he design of a personal workstation, special purpose chip design, VLSI computer architectures, and hardware specification and verification. Progress on these resea...

computer-integrated manufacturing (cim), technologies are presented as solutions tomanufacturing organizations, which need to perform well in all customer-related dimensionssimultaneously. in the literature, cim technologies providing such benefits as more frequentproduction changes, reduced inventory level, improved ability of producing complex parts with ahigh degree of accuracy and repeatabi...

Nowadays sedentary behaviors such as prolonged sitting have become a predominant element of our lives. Particularly in the office environment, many people spend the majority of their working day seated in front of a computer. In this paper, we investigate the adoption of a physically active work process within an activity-promoting office workspace design that is composed of a sitting and a sta...

Performance evaluation plays a key role in manufacturing system design and productivity improvement. Characterizing performance objectively is the first step. Inspired by the underlying structure of tandem queues, we have derived an approximate model to characterize the system performance. The model decomposes system queue time and variability into bottleneck and non-bottleneck parts while capt...

We describe the use of a reconngurable interface board based on FPGAs and a UNIX workstation to implement a correlation tracker with 3.8ms latency. The correlation tracker is part of an active mirror system in use at the The reconngurable interface is used to leverage the workstation CPU, relieving it of tasks that it performs poorly such as rapid context switching and low-level bit manipulatio...

The ability to apply quantifiable mechanical stresses at the microscopic scale is critical for studying cellular responses to mechanical forces. This necessitates the use of force transducers that can apply precisely controlled forces to cells while monitoring the responses noninvasively. This paper describes the development of a micromanipulation workstation integrating two-photon, three-dimen...
