There was an explosive growth in the bioprocess industry market during the last decade. The tight control of these processes is often very critical in order to optimize the process efficiency or even achieve the right product. Capillary electrophoresis (CE) system is a good option for process monitoring and controlling, since it has already been proved to be a powerful analytical tool used in laboratory situations. However the extremely high separation voltage required by CE operation is preventing the system miniaturization and integration, and thus hindering its way to in-line application. Therefore, in this work, two low-voltage separation methods are proposed and investigated with the aim of substituting the conventional microfluidic CE. In the first DEP method, the curved parts of a serpentine channel are effectively used for diel...
Stereo matching has been widely used in many fields, such as viewpoint interpolation, feature detection system and free-view TV. However, the long processing time of stereo matching algorithms has been the major bottleneck that limits their real-time applications. During the past decades, many implementation platforms and corresponding algorithm adaptations are proposed to solve the processing time problem. Although notable real-time performances have been achieved, these works rarely satisfy both real-time processing and high stereo matching quality requirements. In this thesis, we propose a stereo matching algorithm suitable for hardware implementation based on the VariableCross and the MiniCensus algorithm. Furthermore, we provide parallel computing hardware design and implementation of the proposed algorithm. The developed stereo ...
The research in ultrasonic processing for metallurgical application shows a promising influence on improving casting properties of aluminium alloys. The principle of ultrasonic processing is introduction of acoustic waves with a frequency higher than 17 kHz into liquid metal. Several promising beneficial effects caused by ultrasonic processing in aluminium alloys were observed and researched, such as ultrasonic-aided grain refinement, reduction of thermal contraction during solidification, and ultrasonic degassing. The systematic study of this subject allows us to achieve a better understanding of ultrasonic processing in aluminium alloys. It also provides valuable information for optimization of ultrasonic processing parameters in industrial application.
