thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...

Signi cant advances have been made in the area of macro planning for assembly operations (i.e., dividing a product into sub-assemblies, determining the sequence of assembly operations). On the contrary, the state of the art in micro planning (i.e., tool selection, path planning for tool and part movements) is rather primitive. To generate a realizable assembly plan, both macro planning and micr...

In this paper, we show how standard GIS operations like the complement, union, intersection, and buffering of maps can be made more flexible by using fuzzy set theory. In particular, we present a variety of algorithms for operations on fuzzy raster maps, focusing on buffer operations for such maps.
