The purpose of this thesis is non-destructive determination of residual stress state in the multi-pass welded steel plates by Magnetic Barkhausen Noise (MBN) technique. To control the effectiveness of the developed procedure, continuous MBN measurements on the heat affected zone and parent metal of the welded plates were performed. In the experimental part, various steel plates were welded with different number of weld passes. Various series of samples were prepared for residual stress and for angular deflection measurements. Microstructural investigation and hardness measurements were also conducted. The results were discussed to evaluate the effectiveness of MBN measurements to monitor the changes in the residual stress state in the welded components as a function of weld pass number.

This study is an attempt to understand the politics of international film festivals and how it translates into local forms of colonialism. Theroretical review of this study focuses around the politics of festivals particularly through Iranian Cinema in the international frame. Inclusionary/exclusionary mechanisms of film festivals, the notion of national geographic effect and how they formed the canonization of Iranian cinema will be discussed. The thesis has also analyzed an Iranian film Kandahar as a case study with the notion of Orientalism to demonstrate how colonizing gaze organized in festival circuit has been internalized by a national filmmaker.

Forging operation is one of the most commonly used manufacturing techniques in defense industry. The products of forging operation have higher material strength when comparing to traditional manufacturing operations. Especially, for the mass production, it is a beneficial method considering metal and cost saving. The commonly used part named Fin Connector Rod in defense industry requires high material strength due to working conditions. In this thesis, manufacturing of this part by hot forging operation is accomplished after analyzing by using the finite element method. Two alternative forging processes are compared and the applicable alternative method is selected by using a finite element program. Dies are designed for applied processes. The stress distribution and the current temperature variation within the parts analyzed to evaluate the results. The fin connector rod is manufactured according to the results of the finite element analysis. It has been observed that, manufacturing of the fin connector rod by hot forging is succeeded and the waste material and cost is reduced when compared to the machining operation which is being used currently.

This thesis is intended to help eliminate misconceptions and missing information over the realm of smart materials, by offering a newly structured &lsquo / Information Hierarchy for Smart Materials Communication for Industrial / Product Design&rsquo / . Industrial and product designers are invited to use the findings of the thesis to assist in developing a common smart materials language and culture, enriched by details, technicalities, opportunities, and creative and innovative material attributes. The study commences with the creation of a concise and compact reservoir of technical knowledge on smart materials and critically contrasts two established systems of classification for smart materials. Then, the subject of materials information appropriate to industrial design is discussed, highlighting channels through which smart materials information may be communicated at an optimum level so as to be amenable to exploitation by industrial designers. A sectoral analysis of smart materials use follows, including the presentation of factors that may hinder their more extensive exploitation in major industrial sectors. v The thesis concludes that smart materials have potential to initiate a breakthrough in the materials universe, and that industrial designers have a role in promoting smart materials knowledge, the capabilities of smart materials, and their innovation possibilities. It is recomended that since smart materials are a new generation of materials quite different from the conventional, they be promoted carefully through the proposed Information Hierarchy.

This study analyzes the moral development of George Eliot&#039 / s characters in her novel Middlemarch according to Lawrence Kohlberg&#039 / s theory called &quot / The Cognitive-Developmental Theory of Moralization&quot / . Eliot&#039 / s moral view is characterized by man&#039 / s relation with other men, not man&#039 / s relation with God. As long as the individuals treat others with sympathy and understanding, they can develop morally. Eliot&#039 / s aim is to contribute to the creation of a happier society by presenting the harms of egoism. According to Kohlberg&#039 / s theory, individuals can develop their role taking abilities parallel to their cognitive developments. This development is displayed by three levels and at the heighest level an individual can go beyond the expectations of society with principles of justice and respect for basic human rights and dignity. However, although the characters in Eliot&#039 / s novel are sometimes in conflict with the society, they tend to find solutions to their problems within the social structure they live in because Eliot contends that the harmony of society is more important than the personal satisfaction and happiness of individuals for the welfare and happiness of humanity as a whole.

Ball mill grinding is an important operation in the processing of most minerals, in that it may be used to produce particles of the required size and shape, to liberate minerals from each other for concentration purposes, and to increase the powder surface area. Grinding of minerals is probably the most energy consuming task and optimization of this operation has vital importance in processing plant operations to achieve the lowest operating costs. Predicting the complete product size distribution, mill specifications and power draw are important parameters of this optimization. In this study, a computer simulation program is developed in MATLAB environment to simulate grinding operations using the kinetic model in which comminution is considered as a process continuous in time. This type of model is commonly and successfully used for tumbling grinding mills having strongly varying residence time as a function of feed rate. The program developed, GRINDSIM, is capable of simulating a ball mill for a specified set of model parameters, estimating grinding kinetic parameters from experimental batch grinding data and calculating continuous open and closed-circuit grinding behavior with mill power input. The user interacts with the program through graphical user interfaces (GUI&rsquo / s).

EVALUATING TWO SHOPPING CENTERS IN THE LIGHT OF PRINCIPLES OF UNIVERSAL DESIGN Sev&uuml / k, Muhammet Sancar M. of Arch., Department of Architecture Supervisor of the thesis: Prof. Dr. Vacit Imamoglu April 2011, 156 Pages Starting from the second half of the 20th century, the number of aged people and people with aging-related disabilities has increased significantly in the world. Parallel to this increase, special projects have been developed for aged people in the developed countries, but with these projects aged people were often excluded from society. People with disabilities were already living isolated from society. With the effect of raising awareness in the public after the adoption of the Universal Declaration of Human Rights in 1948, in the course of the last sixty years studies have been realized and new standards and principles have been developed for elderly people and people with disabilities to benefit from the social life equally together with everyone and to raise their quality of life. Starting with the barrier-free design approach, a new period improving and changing the view point of design from general and private design to design for all, to inclusive and/or the universal design has begun. In the thesis, this period has been reviewed through the summarized definitions of these stages. The effects of these improvements have been related to the design and construction of the built environments and buildings. Therefore, people with disabilities started to participate in the society more than ever. The implementation of principles of the Universal Design in the public buildings, especially to hospitals, cultural centers and shopping centers has gained more importance in order to advance full social integration of people with disabilities to the society. Number of shopping centers in Turkey increased rapidly after 1995. In this thesis, two examples were examined and evaluated in the light of universal design principles. The problems faced in these buildings were examined in order to design more inclusive buildings and environments. A brief history of shopping centers was presented. Brief information about some examples of old bazaars from Anatolia and shopping centers from different countries were given.

Boolean functions are accepted to be cryptographically strong if they satisfy some common pre-determined criteria. It is expected that any design criteria should remain invariant under a large group of transformations due to the theory of similarity of secrecy systems proposed by Shannon. One of the most important design criteria for cryptographically strong Boolean functions is the nonlinearity criterion. Meier and Staffelbach studied nonlinearity preserving transformations, by considering the invertible transformations acting on the arguments of Boolean functions, namely the pre-transformations. In this thesis, first, the results obtained by Meier and Staffelbach are presented. Then, the invertible transformations acting on the truth tables of Boolean functions, namely the post-transformations, are studied in order to determine whether they keep the nonlinearity criterion invariant. The equivalent counterparts of Meier and Staffelbach&rsquo / s results are obtained in terms of the post-transformations. In addition, the existence of nonlinearity preserving post-transformations, which are not equivalent to pre-transformations, is proved. The necessary and sufficient conditions for an affine post-transformation to preserve nonlinearity are proposed and proved. Moreover, the sufficient conditions for an non-affine post-transformation to keep nonlinearity invariant are proposed. Furthermore, it is proved that the smart hill climbing method, which is introduced to improve nonlinearity of Boolean functions by Millan et. al., is equivalent to applying a post-transformation to a single Boolean function. Finally, the necessary and sufficient condition for an affine pre-transformation to preserve the strict avalanche criterion is proposed and proved.
