Aeroelasticiy of Supersonic Wing Made of Functionally Graded Materials Using Finite Element Method
, M.Sc. Thesis Sharif University of Technology ; Haddadpour, Hassan (Supervisor)
Abstract
The aeroelastic behavior of wings made of functionally graded materials in supersonic flow is studied. For this purpose the flutter speed is calculated and in the next step the post flutter behavior is investigated. The structural model is based on the classical plate theory and material properties are assumed to be graded in the thickness direction according the power law distribution in terms of the volume fraction of material constituents. The linear piston theory which is modified to include thickness effects is used for supersonic aerodynamic modeling. The nonlinear structural model based on the Von-Karman strains is considered for prediction of the post-flutter behavior of the wing....
Towards a Architectural Model for Configuration Management of Software Architecture
, M.Sc. Thesis Sharif University of Technology ; Habibi, Jafar (Supervisor)
Abstract
Given the importance of software architecture in the field of software engineering and its influence, much attention has been paid to it in the past few decades. This has led to significant progress in the development and expansion of the technical foundations of design as an engineered discipline and today is regarded as a mature branch of producing cycle and software development. But considerations related to design based on architecture and activities required to achieve a correct and complete architecture 100 percent is difficult and considering progress of technology, this problem is adding to the concerns in the field of architecture. As a result, different approaches and activities...

Abstract
Nowadays, knowledge is the key to success in all software engineering processes. This valuable knowledge, obtained through analysis, design, development, and maintenance processes of the system, should be saved and reused in designing and developing current and similar systems. Using pre-existing knowledge is a practical approach which reduces design complexity, improves software architecture design and manages software quality. In this paper, we describe an approach to create architecture design knowledge using a hierarchical structure of architectural styles based on quality attributes. Knowledge is most importance asset of our approach that reuses similar domains, correlates architectures...
