In this thesis we will first review the problem of deformable modeling. Due to their corss-disciplinary nature, deformable modeling techniques have been the subject of the vigorous research over the past three decades and have found numerous applications in the field of machine vision. Thus the focus will be on general deformable models for computer-based modeling which can be used for computer graphics, visualization, and various image processing applications. So the state of the art of deformable modeling is discussed. Then the focus of the thesis will be on different approaches for the problem of deformable surface reconstruction in 3D space. Amongs these methods there are two main... 

Nowadays, the modern manufacturing dramatically has changed due to the intense global competition and the globalization of economics, resources, and rapid progress in manufacturing systems, information, computer and information management. Cloud manufacturing systems are a new network-based manufacturing paradigm which by utilizing cloud computing and service generation enables technologies to transfer manufacturing resources into manufacturing services. Moreover, recent researches have shown that security, reliability, and quality are enhanced by cloud computing systems. In cloud manufacturing systems, resources that are located in different geographic points enable the distribution of... 

Employing high-temperature superconducting (HTS) tapes, instead of copper or aluminum wires for winding in a superconducting transformer, results in a series of significant advantages; such as: smaller volume, lighter weight, higher efficieny, greatly extended overload capability, better voltage regulation, lower life cycle cost, fault current limiting capability, lower environmental pollution and lower risk potential against fire hazards.In this thesis, optimal design of flux diverter using genetic algorithm for axial short circuit force reduction in HTS transformers has been performed. Then, multilayered flux diverters have been proposed for reduction of weight and losses. The impact of...
