In this paper the conservative Chandy-Misra parallel simulation algorithm is discussed. The basic algorithm is improved by using null message cancellation, simulation loop optimization and multicasting techniques. The algorithms are used for the simulation of a GSM mobile network application in a distributed workstation environment, Diworse. In the simulation results, special attention is paid ...

Minimally invasive surgical techniques, in particular laparoscopy, have many advantages over traditional surgery, most notably more rapid patient recovery. Limitations of current instrumentation, however, can make laparoscopic surgery awkward for the surgeon. A teleoperative surgical workstation would improve the surgeon's dexterity and control during laparoscopy. This report rst presents a bri...

The General Assembly Line Balancing Problem with Setups (GALBPS) was recently defined in the literature. It adds sequence-dependent setup time considerations to the classical Simple Assembly Line Balancing Problem (SALBP) as follows: whenever a task is assigned next to another at the same workstation, a setup time must be added to compute the global workstation time, thereby providing the task ...

Cobotic workstations in industrial plants involve a new kind of collaborative robots that can interact with operators. These cobots enable more flexibility and they reduce the cycle time floor space workstation. However, also introduce safety concerns regard to operators, may have an impact on workstation ergonomics. For those reasons, introducing always require additional studies ergonomics be...

The process of cutting labels at the Jago Jaya Industry Shuttlecock has not implemented efficient working methods, so production targets are achieved. This study aims to improve method workstation through implementation a label tool in industry. used analyze hand movements uses Right Hand and Left Map. Improved operator be more balanced as increase productivity workstation. time required cut 50...

The ION Data Engine is a multþocessor tasking system that provides data manipulation services for collections of workstations or other conventional computers. It is a back-end system, connecting to a workstation via the Small Computer Systems Interface (SCSÐ disk interface. ION appears to the workstation as a large, high speed disk device, but with user extensible characteristics. By mapping an...

Workstation clusters are becoming more popular as a parallel computing platform. Several programming libraries, including Parallel Virtual Machine (PVM), allow workstation clusters to be programmed as a single parallel computer. The performance of parallel programs is often affected by complex interactions between hardware and software. Performance prediction tools can help characterize the per...

Geophysical techniques coupled with the modern computer workstation have not been widely used in environmental geology. The Kansas Geological Survey is investigating the application of the computer workstation in a number of projects underway that involve environmental questions and problems associated with salt dissolution. The computer workstation provides an efficient approach to integrate g...
