Matlab鼠标画图,用pop-up menu选择画图标记,颜色edit记录鼠标坐标 但是功能比较简单，只能画线，不能画矩形、椭圆等 其中一个难点就是：拖动鼠标的过程中如何显示矩形/椭圆的轮廓，并且轮廓跟着鼠标指针移动。 程序的亮点： 1、可选择点、线、矩形、椭圆进行画图； 2、可选择marker、LineTyple进行画图； 3、可选择画图颜色； 4、可实时显示鼠标指针当前坐标； 5、可清除画板； 6、可保存画好的图(bmp、jpg、gif)； 7、操作比较人性化，模仿了windows画板； 8、该程序牵涉的面广，是一个很好的GUI学习资料。 (Matlab mouse drawing, with the pop-up menu select the drawing marks, color edit record mouse coordinates, but relatively simple function, can only draw a line, not drawing rectangles, ellipses, etc. One of the difficulties is this: how the process of dragging the rectangle/oval contours, and outline follow the mouse pointer moves. Program Highlights: 1, select point, line, rectangle, ellipse for drawing 2, optional marker, LineTyple the drawing 3, choose paint colors 4, real-time display the current coordinates of the mouse pointer 5, to clear the drawing board 6, save-drawn map (bmp, jpg, gif) 7, operation more user-friendly, imitating the windows drawing board 8, the program involved a wide range, the GUI is a good learning materials.)

This paper presents a new and efficient approach for capacitor placement in radial distribution systems (RDS) that determine the optimal locations and size of capacitor with an objective of improving the voltage profile and reduction of power loss. The solution methodology has two parts: in part one the loss sensitivity factors (LSF) are used to select the candidate locations for the capacitor placement and in part two a new algorithm that employs Dijkstra Algorithm (DA) is used to estimate the optimal size of capacitors at the optimal buses determined in part one. The main advantage of the proposed method is that it does not require any external control parameters. The other advantage is that it handles the objective function and the constraints separately. The proposed method is applied to 33 & 69 RDS. The solutions obtained by the proposed method are compared with other methods. The proposed method has outperformed the other methods in terms of the quality of solution. OPTIMAL C

接地技术最早是应用在强电系统（电力系统、输变电设备、电气设备）中，为了设备和人身的安全，将接地线直接接在大地上。由于大地的电容非常大，一般情况下可以将大地的电位视为零电位。后来，接地技术延伸应用到弱电系统中。对于电力电子设备将接地线直接接在大地上或者接在一个作为参考电位的导体上，当电流通过该参考电位时，不应产生电压降。然而由于不合理的接地，反而会引入了电磁干扰，比如共地线干扰、地环路干扰等，从而导致电力电子设备工作不正常。可见，接地技术是电力电子设备电磁兼容技术的重要内容之一，有必要对接地技术进行详细探讨。(Grounding technology was first applied in strong electric system (power system, power transmission equipment, electrical equipment), in order to equipment and personal safety, the ground wire directly connected to the earth. Because the earth capacitance is very large, under normal circumstances can be considered to be zero potential earth potential. Later, grounding techniques applied to extend the weak system. For power electronic devices directly connected to the ground wire on the ground or connected to a reference potential as a conductor, when the current through the reference potential, and should not generate voltage drop. However, due to unreasonable ground, but will the introduction of electromagnetic interference, such as co-ground interference, ground loop interference, resulting in power electronic equipment is not working properly. Visible, grounding technology is an important part of power electronic equipment EMC technology, it is necessary for grounding techniques disc)
