Fragmentation measurement using image processing
In this research, first of all, the existing problems in fragmentation measurement are reviewed for the sake of its fast and reliable evaluation. Then, the available methods used for evaluation of blast results are mentioned. The produced errors especially in recognizing the rock fragments in computer-aided methods, and also, the importance of determination of their sizes in the image analysis ...

متن کاملSound velocity measurement using transfer function method
Abstract The transfer function of a piezoelectric transducer, buffer rod and sample assembly is used to measure the sound velocity of solid materials. From the recorded transfer function, pulse echo patterns at frequencies of the passband of the input signal are reproduced after convoluting with monochromatic RF input signals. The time delay is obtained by performing pulse echo overlap and phas...
متن کاملSpeech and Picture Processing
During the first half of the contract year, the program continued the following studies: speech analysis by linear prediction, digital frequency warping, development of a high speed digital processor for speech synthesis, and the design of two-dimensional recursive digital filters. These projects are summarized in the following pages and reprints of available publications are appended.
