disciplined inquiry about problems of organization and management requires decision to be taken about an appropriate research deign. in making such a decision, the researcher tacitly assumes a philosophical point of view or a research paradigm. there are four research paradigms which are the basis for the selection of research methodology and research methods. these paradigms include: a) positi...

genetic algorithm (ga) has been extensively used in recent decades to solve many optimization problems in various fields of science and engineering. in most cases, the number of iterations is the only criterion which is used to stop the ga. in practice, this criterion will lead to prolong execution times to ensure proper solution. a novel approach is presented in this article as the approximate ...

Agent oriented software engineering (AOSE) is an emerging field in computer science  and  proposes some systematic ideas for multi agent systems analysis, implementation and maintenance. Despite the various methodologies introduced in the agent-oriented software engineering, the main challenges are defects in different aspects of methodologies. According to the defects resulted from weaknesses ...

The management of distributed software development projects presents many challenges. One of them happens right at the start of the project and consists of the allocation of tasks between remote teams. When allocating a task to a site, the project manager takes into account several factors such as technical knowledge of staff and proximity to the client. The project manager usually takes this d...

In this study, we tested the hypothesis, derived from the theorizing of Derryberry and Tucker (1994), that the mere enactment of approach or avoidance behavior, without concomitant pursuit of personal approach or avoidance goals, can independently moderate the scope (i.e., breadth or narrowness) of attention on both the perceptual and conceptual levels. SpeciWcally, we predicted that enactment ...

Abstrakt In this note we critically examine the current state of teaching of Discrete Simulation at our university. We consider the case study of one of the projects that students are expected to solve in the course. Three approaches are compared nonmodular resulting from the current approach, using Haskell, and using Reactive framework from C#. We conclude that functional approach can address ...

In addition to its intrinsic practical importance, nonlinear time delayed feedback control applied to lifting surfaces can result in interesting aeroelastic behaviors. In this paper, nonlinear aeroelastic response to external time-dependent loads and stability boundary for actively controlled lifting surfaces, in an incompressible flow field, are considered. The structural model and the unstead...

The development of service-oriented applications has reached a point where more specifications are needed to enable holistic transparent service-management. A three-schema-architecture for design of servicebase-management-systems according to the ANSI/SPARC-model for database design is proposed in this paper. The conceptual schema of the proposed architecture decribes the servicebase, what prov...

There exist two formulations of rough sets: the conceptual and computational one. The conceptual or semantical approach of rough set theory focuses on the meaning and interpretation of concepts, while algorithms to compute those concepts are studied in the computational formulation. However, the research on the former is rather limited. In this paper, we focus on a semantically sound approach o...
