Despite the great effort devoted to the development of Workflow models and Workflow Management Systems during the last decade, a strong foundation about workflow development is still to come. Assuming that a workflow is a complex software product, in this paper we argue that the principles and techniques of software development — in particular, methodological concerns— can help in the developme...

methanol as a biofuel is an environmental friendly substitute to pure diesel and can be obtained from biomasses. use of biofuels such as methanol for combustion process is associated with positive environmental impacts. using pure methanol or blended with diesel fuel in automotive has been proposed by researchers. in this paper, methanol was injected into combustion chamber of a ism 370 hd dies...

Information retrieval emerged as independent research area from traditional database management system more than a decade ago. This was driven by the increasing functional requirements that modern full text search engines have to meet. Current database management systems (DBMS) are not capable of supporting such flexibility. However, with the increase of data to be indexed and retrieved and the...

Advanced information retrieval and database management systems employ a variety of elaborate data representation, indexing and retrieval techniques, but usually apply less elaborate – often simplistic – models of the human-computer interaction. Effective interaction, however, is essential for effective information retrieval. To be able to assist and guide the user actively through the entire in...

background: quality management is one of the most effective strategies for improving the health systems performance in developed and developing countries. the main goal of this study was identifying the most important aspects of quality management and preparing an appropriate model for health system. method: this research was a comparative study on quality management models in the health system...

A Grid Workflow is critical to grid computing for its ability of creating complex grid computation by connecting different grid jobs logically. User can easily define and reuse the workflow for their applications that are loosely coupled. In this paper, we proposed a Grid Workflow Management System (GWMS) to provide the interface of processing workflow with grid schedulers, e.g., Sun Grid Engin...

This is an exploration to foretell a future in which traditional approaches for developing workflow management systems can be supplanted by new techniques and emerging technologies. This thesis recommends sets of methodologies for performing multiagent-based distributed and flexible workflow systems. Its objective is to deal with some of the present issues in the traditional workflow system fro...
