we have devided the thesis in to five chapters. the first recollects facts from purely algebraic theory of jordan algebras and also basic properties of jb and jb* - algebras which are needed in the sequel. in the second chapter we extend to jb* - algebras, a classical result due to cleveland [8]. this result shows shows the weakness of jb* - norm topology on a jb* - algebera. in chapter three, ...

there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...

Deterioration of urban textures is an issue that most cities in Iran are faced with and the organization of such textures is of great importance. One of the safest and most practical solutions for urban planners is to assess the feasibility of regenerating such textures to determine the levels that can be regenerated and are relatively good and tolerable for urban society. Therefore, the presen...

Extended Abstract Introduction Urban vulnerability to environmental disasters in countries with high environmental risks has converted into a severe issue. Even though the relevant literature indicates that corresponding studies urban historical deteriorated physical structures started seven decades ago, literatures pertaining vulnerability to earth quake go back to mid 1970s.Vulnerability ...

a novel ultra wideband microstrip bandpass filter using radial stub loaded resonator and interdigital coupled lines is presented in this paper. the radial stub loaded resonator and decagonal patch form a resonator named m to create tuneable multiple notches in the passband for suppression wlan interference. to realize sharp roll-off, two adjustable transmission nulls are located at the lower an...
