rain modeling in recent years has been of great importance in water resource management and its function in long term and short term planning, especially its great effect on agricultural economy. to reach to good results box-jenkins model is much more efficient. the writers of this article have used the data collected in tabriz and oroumiyeh stations in a fifty year period and then presented th...

A. J. Keel M. A. Orr R. R. Hernandez E. A Patrocinio J. Bouchard In this paper we focus on information technology service management (ITSM), a new direction for managing information technology (IT) organizations that requires a change from a technology-oriented to a service-oriented approach to IT management. We first examine the main challenges to implementing ITSM, which span four broad areas...

viscosity (µ) and density (ρ) are important physical roperties for analysis of membrane processes performance and for designing a new membrane process. in addition, the energy requirement for fluid pumping is depend on these two physical properties magnitiude. in this study, firstly, the effects of different process factors such as transmembrane pressure (51, 101, 152, 203 and 253 kpa), tempera...

Often in modeling the engineering optimization design problems, the value of objective function(s) is not clearly defined in terms of design variables. Instead it is obtained by some numerical analysis such as FE structural analysis, fluid mechanic analysis, and thermodynamic analysis, etc. Yet, the numerical analyses are considerably time consuming to obtain the final value of objective functi...

In this paper we present an object-oriented approach and a development environment for the system-level design of run-time reconfigurable computer systems. We use the Unified Modeling Language for the specification, modeling, and visualization throughout all phases of development. We show how object-oriented applications can be implemented and executed on custom computing machines comprising ru...

this paper illustrates the design and implementation of fain (filtering agent for internet) based on the gaia methodology and the auml notation. the proposed system generates and maintains a user profile by learning from examples that are judged and classified by the user during the training stage. a learning algorithm which is based on the baldwin effect that combines learning with evolution i...
