Tendency and requirement to transform and process information quickly forced us todesign and make circuits that can work in high frequency.. At this time there are differenttypes of high frequency devices for which their models for CAD are necessary. As far as I knowin the latest version of Spice only a class of five types of the MESFET model is available.Because of Advanced ANN training create...

freshwater resources represent around 3% of all water on earth, and less than 1% of that is available. consideringcurrent conditions, as well as future predictions of need, freshwater resources cannot meet human needs. thus,sweetening of the brackish water can be performed to provide freshwater for human use. solar energy, because ofiran's climatic conditions, may be used for sweetening the bra...

in the developed countries, many organizations are regarded as knowledge-based businesses in which knowledge management is necessary. today, this science is changing into integral activity of business in organizations. one of the concerns of knowledge management is its implementation.many companies and organizations which try to start knowledge management don’t ensure that the best approach is ...

this paper describes the application of process integration principles to the design of oil refineries hydrogen network. in this regard, a design hierarchy as well as heuristics and required guidelines are proposed. the recommended rules compensate lack of procedure to the design and make the design process easier. the guiding principles of the design are based upon pinch technology and extendi...

Abstract   The Analytic Network Process (ANP) is a generalization of the Analytic Hierarchy Process (AHP). The basic structure is an influence network of clusters and nodes contained within the clusters. Priorities are established in the same way they are in the AHP using pairwise comparisons and judgment. Many decision problems cannot be structured hierarchically because they involve the inter...

the main purpose of this paper is to present a fuzzy multi-criteria decision making (fmadm) model for appropriate location selection of a health center. therefore, we identify sixteen criteria and sub-criteria for selecting a health center location. these criteria and sub-criteria have been obtained from literature reviews and practical interviews. this paper proposes a method which combines th...
