The phase-vocoder is a well-known tool for the frequency domain processing of speech or audio signals, with applications such as time compression or expansion, pitch-scale modification, noise reduction, etc. In the context of time-scale or pitch-scale modification, the phase-vocoder is usually considered to yield high quality results, especially when large modification factors are used on polyp...
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...
