The purpose of single source separation is to recover a particular signal from a mixed signal. This work develops a novel source separation method for use with an automatic speech recognition (ASR) system. The proposed method is based on non-negative matrix factorization (NMF), which is extensively used in single channel source separation. In the cost function, a flexible distance, αβ-divergence,...
The research on clinical data is one of the fastest growing fields all over the world. In general, most of the data have imbalanced issues, which may cause some problems in the researches. In this study, the methods of over-sampling and under-sampling are used for handling the issues of data imbalanced. The case based reasoning (CBR) is used for developing classification models to predict recurrent...
This paper developed an automatic optical inspection (AOI) technology for characterizing the motion amplitude and the vibration mode shape of in-plane micro-actuators. The technology involves a multi-stage image process method. It includes an image contrast enhancement step and a Canny edge detection method. To evaluate this approach, a rotational electrostatic actuator has been prepared for testing...
This research presents a new and noncontact method to measure the adhesion strength between micro-particles and substrates in parallel. It is cost effective and time saving. In this study, the adhesion strength between micro solder ball and PDMS (polydimethylsiloxane) and ReproRubber® (polymethylhylhydrogen) are investigated. The setup is capable of evaluating more than 8 particles separately each...
