In the paper the analysis of wax pattern and casting dimensions changes during each stages of investment casting technology process has been presented. Results of wax patterns and castings of test plate free and restrained contractions dimensions changes research carried out in Department of Foundry Engineering at Brno University of Technology have been presented as well. Moreover obtained resu...

SU detection is specific to the context of automatic speech recognition (ASR) systems, which typically produce an unstructured sequence of words from an audio signal, and must then recover latent structural features in the signal such as word case (“true-casing”) and sentence boundaries (“SU detection”) in order for the output to be ready for human consumption. Recent efforts by the DARPA EARS ...

Ever increasing demand of higher pressure ratio of aero-engine compressors has always been hindered by two distinct aerodynamic instabilities. The first known as surge is; large one dimensional periodic mass flow fluctuation through the compressor, which involves the entire pumping system including compressor, ducting, plenum and throttle. The second is the rotating stall which can be character...
