The reliability is the important performance of high power semiconductor laser. Thermally accelerated ageing test is an important technology of lifetime evaluation and reliability analysis. In this study, three groups of thermally accelerated ageing tests of conduction-cooled-packaged 60W 808nm high power diode laser arrays packaged by Indium solder at constant current have been carried out. Analysis...
In this paper, we propose a novel method that is capable of detecting and removing moving cast shadows robustly. Four properties of the moving cast shadows are observed. To make full use of the four properties, pixel level processing is adopted to extract the color, texture and luminance features of the moving foreground, and region level processing is introduced to detect shadows. Another innovation...
In order to optimize the performance of the steam turbine unit performance monitoring system, improve the reliability, stability and accuracy of the system, a new idea to establish target value surface and coal consumption growth surface in different load is presented. Take an imported supercritical steam turbine unit, which capacity is 600 MW, as an example to expound the design idea, the mathematic...
Either as a significant augmentation of GPS system, or as an independent system for indoor positioning, pseudolites augmenting GPS technique has become an exciting technology whose potential can be explored for a wide range of positioning and navigation application. Indoor positioning using multiple pseudolites signals, however, comes up against a number of obstacles, and there are some challenging...
