This paper suggests a method for designing PSS to damp multi-machine power system oscillations.  The method is based on robust control theory. First, the conventional method for designing robust controller in LMI framework is illustrated. Then, the suggested method is given, in which, a PID output feedback controller is tuned using the LMI approach. Mostly, the classical methods are used t...

this paper addresses the concept of co 2 laser beam machining (lbm) and development of intelligent knowledge base system (ikbs) for co 2 lbm. feature based design is used for acquiring design specification. for optimization of laser beam machining computer based concurrent engineering environment is used. the ikbs is linked to feature base cad system. the ikbs is also linked to material databas...

without the surrounding environment of a site, architecture loses its full meaning. in the evolutionof the design process, a site's environment should be understood as the integral factor within which a designed productor artifact is expected to perform. the environment is not of secondary priority. every building is intertwined with itscontext; context being its physical, visual and ecological...

different models with various approaches to strategic positioning have been employed to define it in various industries. as one of the powerful models, bsc analyses all aspect of organization evenly. in this study bsc is used as an instrument to make shiraz university more efficient in implementing strategic and performance or supporting their strategic plan. therefore this study aims to design...
