nowdays, production of high quality engine oils is one of the worries of our country’s engine oil industry. in this study, the behavior of four commercial polymers used in nation motor oil industry in obtaining the best viscosity index improver was investigated. in this regard, viscometric behavior, shear stability and polymers’ performance for engine cranking were compared at low temperature. ...

The majority of our citizens are aware of the contributions of nuclear technology to the production of electricity via commercial nuclear power plants. But most are unaware that the impact of this technology is even greater for non-power applications. The world of medicine, agriculture, and modern industry has been substantially improved by the harnessing of radioisotopes, and new applications ...

Open Source Software (OSS) expresses the idea that developers should be able to license the publication of their software in a manner permitting anyone to freely use, modify, and distribute the software. Today OSS is widely used in the software industry, such as for language development tools (e.g., NetBeans for Java), office document processors (e.g., OpenOffice), and operating systems (e.g., ...

Finally, experiences and lessons learned from the system are presented. The system is designed to be able to provide traditional television service, video-on-demand service, and custom interactive applications, such as...

This paper describes results from a project aimed at developing computer exercises to be used in teaching undergraduate and graduate courses in the power engineering area. The paper first describes details about the project which is funded by the National Science Foundation, Electric Power Research Institute and a number of industry sponsors. After that, a customized power education toolbox dev...

For many years, free and open source software was exclusively associated with the research community, in contrast to the closed source products developed by commercial software vendors. Over the past decade, there has been a vast increase in the availability of open source software, growing from such projects as Linux and Apache. Open source software is being widely adopted in industry, which h...

Commercial software component models are frequently based on object-oriented concepts and terminology with appropriate binding, persistence and distribution support. In this paper, we argue that a process-oriented view on cooperating software components based on the concepts and terminology of a language/action perspective on cooperative work provides a more suitable foundation for the analysis...
