The impact of user interface quality has grown in software systems engineering, and will grow further with upcoming new paradigms such as Ambient Intelligence or Ubiquitous Computing, which confront the production industry with a huge diversity of new usage situations. In this paper, we will show the adaptation of a task-oriented useware modeling language, which is employed in the model-based u...

The objective of our work is to develop a platform independent management architecture for open distributed systems. In this paper we describe one component of this architecture which enforces the observance of formally definable management policies and executes clerical management tasks automatically. Management components are defined in terms of an objectoriented class structure and policies ...

The rotavirus nonstructural protein 4 (NSP4), is a multi functional protein that play key role in both viral morphogenesis and cytopathic effect associated with cell death. However, the complete biological effect of NSP4 remains to be clarified. Since to obtain further knowledge about this protein there is a need for recognizing antibody and there is no commercial antibody against this protein,...

Although initially originated as a totally empirical relationship to explain the volume of trade between two partners, gravity equation has been the focus of several theoretic models that try to explain it. Specialization models are of great importance in providing a solid theoretic ground for gravity equation in bilateral trade. Some research papers try to improve specialization models by addi...

this study investigates the role structural priming plays in production of passive structures among iranian efl learners. in order to answer the research question, which asked whether structural priming effects result in an increase in the production of the target structure (i.e., passive structures), 60 iranian efl learners participated in the study. after taking the placement test, they were ...
