[Software Engineering] as DL : 0: To improve the boiler drum level control system of a power plant, the three challenging issues encountered include (1) effect of ‘‘false water level’’, (2) controller parameter mismatches due to variant working conditions and (3) signal noise caused by uncertainties of drum level. In this paper, based on analyses of the drum level signal, an adaptive derivative action is presented to monitor steam flow, and thus, the effect of ‘‘false water level’’ is weakened. The uncertainties of parameter mismatches and noise are predicted by developing a Grey predictor based algorithm (GPBA). In order to resolve the three problems and further control performance, an adaptive technique is combined with the GPBA to develop an adaptive Grey predictor based method. Finally, concrete simulations give that the proposed method has obvious superiority over conventional methods.

[Software Engineering] WaveletTransform DL : 0: 边缘是图像中最重要的信息，是模式识别、图像分割以及场景分析的重要基础。边缘检测是图像处理领域一项重要的技术和任务。图像中边缘通常解释为灰度值有突然改变，像素梯度具有局部极大值。很多经典的边缘检测算子如:Roberts, Sobel, Prewitt, Frei- Chen和Laplacian等，均以图像局部区域特征与特定边缘模式匹配为基础，定义数个方向导数模板(一般为窗口)，将图像与模板进行卷积运算实现边缘检测。它们具有实现简单，速度快速，易于应用的特点。当模板方向与边缘方向相匹配时，能取得非常有效的边缘检测结果。 -The edge is the most important information in the image, and is an important basis for pattern recognition, image segmentation and scene analysis. Edge detection is an important field of image processing technologies and tasks. Edge in the image is usually interpreted as grayscale values sudden changes in pixel gradient local maxima. Many classic edge detection operators such as: Roberts, Sobel, Prewitt, Frei-Chen and Laplacian, etc., are the image of local regional characteristics specific edge pattern matching based on the definition of a number of directional derivative template (usually a window), the image convolution operation of edge detection with a template. They have a simple, fast speed, easy to apply. When the template direction and the edge direction matches, can achieve very efficient edge detection result.
