Businesses need fast computing environments to quickly process the voluminous transactions and to respond to market requirements. Most companies cannot afford the cost of a supercomputer. As an experimental design, the authors have developed a cluster-computing project at their institution, to expose business students to the process of building and operating a cluster computer for use in superc...

introduction: one of the software packages designed for libraries and documenting centres is unesco cds/isis mini-micro software package. most libraries in iran have a copy of it. this research was aimed to investigate the degree of its application in central libraries of medical sciences universities in 2004. methods and materials: it is a descriptive study in which a questionnaire was used to...

Introduction: Mobile phones and computers are a reservoir of growth and transmission of microorganisms. This study aimed to evaluate the microbial contamination of computers and mobile phones used by students of an academic dental school, compared to the students of a non-medical school. Methods: Sampling was performed on 44 computers and 45 mobile phones in a dental school (test) and a non-med...

The simulation of morphodynamical processes with a 3D model requires high horizontal and vertical resolution at least in some parts of the model domain. In particular, all areas with steep bathymetry gradients like tidal rivulets or shipping channels require highly resolved simulations. Since it is not feasible to run the total model domain with the same high resolution everywhere, this problem...

The aim of this study was to describe and find out motivational English language learning strategies through computers among Iranian EFL learners and find out how learners’ motivations change towards English language learning through computers.The mixed method approach (quantitative and qualitative) was employed in this study. A total of 84 (out of 130) female freshman university learners from ...

800x600 as a tendency to use new technologies, gadgets such as laptop computers are becoming more popular among students, teachers, businessmen and office workers. today laptops are a great tool for education and learning, work and personal multimedia. millions of men, especially those in the reproductive age, are frequently using their laptop computers on the lap (thigh). over the past several...

A cluster is a group of computers which are loosely connected,together to provide fast and reliable services. There have been many applications built on cluster systems such as distributed/parallel database applications, telecommunication systems and, recently, internet/intranet servers. Cluster systems can deliver similar or better performance and reliability than traditional mainframes, super...

Until recently, cluster computing was too expensive and too complex for commodity users. However the phenomenal popularity of single board computers like the Raspberry Pi has caused the emergence of the single board computer cluster. This demonstration will present a cheap, practical and portable Raspberry Pi cluster called Pi Stack. We will show pragmatic custom solutions to hardware issues, s...
