02 is the Object-Oriented Database System being developed at Alta’ir. The 02 Object Manager is the layer of the system concerned with complex object access and manipulation, transaction management, persistence and disk management., and distribution in the server/workstation configuration. This paper describes the main choices made in the design of the Object Manager, and presents its overall ar...

Storage on Network has, always, been a key feature of the success of the network design. Various methods are in practice. Two techniques are suggested in this paper. Disk Clustering and a technique to have Uniform namespace KINDFS is a distributed file storage system designed to provide cost-effective storage service utilizing idle disk space on workstation

[Purpose] This study compared the forward head angle and the lumbar flexion and rotation angles of computer workers using routine and fixed computer workstations. [Subjects] Ten male workers voluntarily consented to participate in the study. [Methods] A 3-D motion analysis system was used to measure the angles of the forward head and lumbar flexion. All subjects performed computer work for 30 m...

This paper explores in detail the workstation and network performance issues for multimedia conferencing and collaboration. For concreteness of exposition, we consider two generic multimedia workstations \conversing" over an Ethernet. In order to facilitate a continuous play-out of voice and video streams, a timely transport across the workstation and the Ethernet is necessary. A cursory look a...

We present the design and implementation of CAOS, a domainspecific high-level programming language for the parallel simulation of extended cellular automata. CAOS allows scientists to specify complex simulations with limited programming skills and effort. Yet the CAOS compiler generates efficiently executable code that automatically harnesses the potential of contemporary multi-core processors,...

OBJECTIVE The literature on psychosocial job factors and musculoskeletal pain is inconclusive in part due to insufficient control for confounding by biomechanical factors. The aim of this study was to investigate prospectively the independent effects of effort-reward imbalance (ERI) at work on regional musculoskeletal pain of the neck and upper extremities of call center operators after control...

Background &Aims of the Study: Nowadays heat stress is one of the most current harmful physical agents in workplaces. Attentions to recognized consequences of heat stress and have no information about heat stress in Ardabil bakeries, this study have been done in 2013. Materials & Methods: This cross sectional research has been done in 96 different bread types bakeries in ...
