Improved methods of constructing wells and producing wells are one of the keys to increasing field profitability. In the areas of well construction and well productivity optimization, many of the problems encountered are related to the geomechanics of the reservoir and the overlying layers; these problems include well-bore stability, sand production and hydraulic fracturing. Hydraulic fracturing is a complicated phenomenon in which deformation of the porous medium and fluid leak-off to the surrounding area take place simultaneously. Their interaction, therefore, must not be overlooked. In the past, some experimental researchers performed laboratory investigations on the phenomenon of...

Cognitive radio is a tool for optimal use of radio spectrum, not used by the primary users all the time. Two main features of a cognitive radio are cognitive capability and reconfigurability. An intelligent cognitive radio uses its cognition ability to identify the environmental parameters and makes future decisions based on this information. Then the reconfigurability is used to set the sending parameters to the calculated values in the cognition phase. Cogition phase consists of major steps; spectrum sensing, decision, mobility and handoff. Throughout this thesis we first propose a cooperative sensing scheme using algorithmic techniques based on sensors’ spatial information through...

Analytic hierarchy process (AHP) is a structured technique for organizing and analyzing complex decision. This process is used around the world in a wide variety of decision situation, in fields such as government, business, industry, healthcare, and education. In this method, decision problem first is decomposed into a hierarchy of more easily comprehended sub-problems, each of which can be analyzed independently. Once the hierarchy is built, the decision makers systematically evaluate its various elements by comparing them to one another two at a time, with respect to their impact on an element above them in the hierarchy. In this thesis we will study the hierarchy process and also study a...

In this research, the aim is to find the factors that can influence on the utility perception of both private buyers and experts. What's more, the share of each factor on the overall utility is derived by the use of AHP technique. The next step is to derive a model that contain all the factors seen by private and inexpert buyers., and their relative weight. At the next step, the aime is to complete the model by adding the factors not seen by all private buyers, but advised by residential apartment experts and their relative weight. The model should be able to rank different residential apartments, when the value of each factor is given for each ot the apartments.
An appropriate approach for evaluation and optimization of performance Gas Turbo-Compressor Stations, M.Sc. Thesis Sharif University of Technology ; Eshragh Niaye Jahromi, Abdolhamid
Since early classical theories presented in management, consistently the evaluation of organization as one of the methods of control and planning has been considered. Besides due to intensification of competition among organizations, it is very important to consider performance evaluation as an effective tool in this regard. In this research DEA/AHP approach has been proposed for measuring performance organizations with fractal structure. Thus regardless of other units the first DEA model for evaluation of each pair of units is used and then a matrix of pairwise comparisons is made and the Analytical Hierarchy Process (AHP) model for two-level ranking is used. Finally the mentioned model for...
