Normal aging is usually accompanied by increased difficulty learning new information. One contributor to aging-related cognitive decline is decreased intrinsic excitability in aged neurons, leading to more difficulty processing inputs and remodeling synapses to store new memories. Two measures of excitability known to be altered by learning are the slow afterhyperpolarization (sAHP) after a bur...

The river ranking problem is a strategic issue and has significant impact on the efficiency of a river system. On the other hand, the river ranking among many alternatives presents a multi criteria decision making (MCDM) problem. Hence fuzzy set theory can be applied. Fuzzy Analytic Hierarchy process (FAHP) technique is used to rank alternatives to find the efficient use of the river system. Fu...

In order to establish the appraisal target system, the principles and methods of the Fuzzy Analytic Hierarchy Process (FAHP) were described in aspects of structuring the comparative judgment matrix described by interval numbers, solving both the interval weight vector and the comprehensive weights of the general target determined by various layers, and selecting the strengthening proposal out o...

Underground mining method selection is one of the most crucial decisions that should be made by mining engineers. Choosing a suitable underground mining method to carry out extraction from a mineral deposit is very important in terms of the economics, safety and the productivity of mining operations. The aim of this study is developing a fuzzy model to selection the optimum mining method by usi...

Abstract Cloud Manufacturing (CMfg) is a new manufacturing paradigm that promises to reduce costs, improve data analysis, increase efficiency and flexibility, provide manufacturers with closer partnerships. However, most past CMfg research has focused on either the information technology infrastructure or planning scheduling of hypothetical system. In addition, cost effectiveness application ra...

Despite the innovative trends in marine technology and the implementation of safety-related regulations, shipping accidents are still a leading concern for global maritime interests. Ensuring the consistency of shipping accident investigation reports is recognized as a significant goal in order to clearly identify the root causes of these accidents. Hence, the goal of this paper is to generate ...

This study analyzes a barrier of developing Exchange named lack of information related to performance of organization. This paper proposes a combined approach to decision making that Examine companies financial performance and offers an optimal way to solve the problem of ranking and efficiency survey. FAHP-TOPSIS approach is used to rating companies and FAHP-DEA approach is used for efficiency...

In recent years, the mobile devices are equipped with several wireless interfaces in heterogeneous environments which integrate a multitude of radio access technologies (RAT’s). The evolution of these technologies will allow the users to benefit simultaneously from these RAT’s. However, the most important issue is how to choose the most suitable access network for mobile’s user which can be use...

To help the client to select a competent agent construction enterprise (ACE), this study aims to investigate the selection standards by using the Fuzzy Analytic Hierarchy Process (FAHP) and build an evaluation mathematical model with Grey Relational Analysis (GRA). According to the outputs of literature review, four orderly levels are established within the model, taking the consideration of va...
