the current thesis is composed in five chapters in the following fashion: chapter two encompasses the applied framework of the project in details; the methodology of carl gustav jung to explain the process of individuation, the major archetypes and their attributes and his techniques to assess the mind’s strata are all explained. moreover, the austrian psychoanalysts, heinz kohut’s models of a...
the present study was an attempt to conduct a contrastive analysis between general english (ge) and english for specific purposes (esp) texts in terms of cohesion and cohesive devices. to this end, thirty texts from different esp and ge textbooks were randomly selected. then they were analyzed manually to find the frequency of cohesive devices. cohesive devices include reference, substitution, ...
abstract this paper discusses several commonly used models for strategic marketing¹ including market environmental analysis methods (i.e. swot and pest analysis) and strategic marketing tools and techniques (i.e. boston matrix and shell directional policy matrix)and shows how these models may help a firm to achieve its strategic goals. at first, the main reason for doing this research is de...
Exact dynamic analysis of piers due to lack of information about their constituting sub systems, is very complicated. Ordinary finite element methods cannot be used in modeling of complex dynamic systems such as these structures since many uncertainty factors exist which cannot be identified exactly. In addition to physical modeling of a pier structure, existence of uncertainty in dynamic behav...
it is correct control and monitoring of modern embankment dams that are very vital in the geotechniqual constructions. the improvement of methods of stability control, using the effective stress and the measurement of ganglionic water pressure in embankment dams cause more the safety for this kind of dams. nowedays there is such an idea that in stead of using of being safety factor against coas...
The finite element method (FEM) can be applied to practically analyze the tall buildings in which the shear walls are used to resist the lateral loads. Accordingly, a variety of displacement and strain-based as well as frame macro elements have been proposed for analysis of the tall buildings. With respect to application of the lower order plane stress elements, analytical problems may arise wi...
Fatigue analysis and estimation of safe life of structures that are subjected to cyclic loadings, such as ships and offshore structures is one of the most important steps of structural design. Fatigue failure in the form of crack will start from details and propagate in structure. In steel structures these cracks will started from welds. Most of the methods for fatigue life assessment in welded...
Evaluation of stress distribution in endodontically treated teeth, restored with post and crown by finite element analysis Dr. H. Kermanshah * - Dr. M. Mirzaee* - Dr. L. Ranjbar Omrani** *- Assistant Professor of Operative Dentistry Dept. - Faculty of Dentistry–Tehran University of Medical Sciences. **- Operative Dentistry Specialist. Background and Aim: Proper restoration of root canal treated...
Laser welding is a novel method for direct joining of metals and polymers, which leads to a mechanical and chemical bond between metal and polymer. In this study, feasibility of dissimilar joining between St12 and polycarbonate is studied theoretically. Then, the ND: YAG laser is implemented to join St12 and Polycarbonate. Empirical results indicate creation of a joint between St12 and polycarb...
