    In this paper, a full adder cell based on a parallel design using MOSFET ‎technology is presented. The main goal of designing this full adder cell is to reduce ‎critical path delay in adder circuits. The proposed design by reduces length of data ‎path and positively, affects speed and power consumption parameters. In order to ‎evaluate the proposed full adder cell, several simulations are performed in ‎different load capacitors, frequencies and temperatures using HSPICE in 32nm ‎CMOS technologies. The proposed full adder cells were compared with eight other ‎full adder cells using 4-bit Ripple Carry Adder (RCA) and 8-bit RCA circuits in ‎power consumption, speed, and Power Delay Product (PDP) parameters. The ‎obtained results indicate that the proposed design is faster than other designs due ‎to a shortened data path. The results of the simulations confirm the higher efficiency ‎of the proposed full adder cell with respect to other designs. ‎

    Strategy map is a human based activity that combines the knowledge and organizational managers’ opinions. This point of view is a kind of group decision making that is determined by our existing relation between the accepted objectives of experts and organizational decision makers (DM). In this study, to design a strategy map for Fanap Company, the combined approach of Analytical Network Process (ANP) and Decision Making Trial and Evaluation (DEMATEL) were applied to determine the systematic interactions between criteria and the relationship between criteria, respectively. In this paper, the results about the importance of relations between strategic objectives level by combined approach, were compared to the importance of relations between AHP strategic objectives level, calculated by Fanap Company’s experts and managers. The final results showed that the importance of strategic relations between BSC levels to achieve the strategic objectives in this company in combined approach was more than AHP method.

    Web development goal was information resources sharing between individuals and organizations. While resources is increasing, our processing capacity about a particular subject remains unchanged. Decision making in any field with available information resources on the web has a significant impact on human life. In this paper, an AHP method is proposed which pays attention to the concept of trust dimensions for available information resources credibility evaluation on the web. Our proposed method based on the existing ontology with a semantic search engine extracts various attributes to evaluate the credibility of a resource and assigns a numerical value using experimental evaluation. To confirm the correctness of the proposed method, an experiment has been organized to select a book based on the author's academic degree, author's reputation, publication year, publisher's reputation, organization and structure, price and etc. The feature ranking of mentioned book is performed, and finally, achieved results are expressed.
