摘要: The grouping of sensors is a calculation method for partitioning the wireless sensor network into groups, each group consisting of a collection of sensors. A sensor can be an element of multiple groups. In the present paper, we will show a model to divide the wireless sensor network sensors into groups. These groups could communicate and work together in a cooperative way in order to save the time of routing and energy of WSN. In addition, we will present a way to show how to organize the sensor 阅读全文

摘要: Due to the limited communication range of WSN, the sensor is unable to establish direct connection to the data collection station, therefore the collaborative work of nodes is highly necessary. The data routing is one of the most fundamental processes exploring how to transmit data from the sensing field to the data collection station via the least possible number of intermediate nodes. This paper addresses the problem of data routing based on the sensors grouping; it provides a deep insight on 阅读全文

摘要: An Autofocus (or AF) optical system uses a sensor, a control system and a motor to focus fully automatic or on a manually selected point or area. An electronic rangefinder has a display instead of the motor; the adjustment of the optical system has to be done manually until indication.[wiki] Focus the out coming light beam of lens on none- Smooth panel 阅读全文

摘要: anel controls are most often used as—and are intended as—containers for other controls. They're often useful when you want to show or hide a group of controls at once, or when you want to add controls to a Web page in code. The figure below show four panels top, left, bottom and right 阅读全文

摘要: The NumericUpDown control looks like a combination of a text box and a pair of arrows that the user can click to adjust a value. The control displays and sets a single numeric value from a list of choices. The user can increase and decrease the number by clicking up and down buttons, by pressing the UP and DOWN ARROW keys, or by typing a number. Clicking the UP ARROW key moves the value toward its maximum; clicking the DOWN ARROW key moves the position toward the minimum 阅读全文

摘要: The TreeView control displays a hierarchy of nodes, like the way files and folders are displayed in the left pane of the Windows Explorer feature in Windows operating systems. Each node in the tree view might contain other nodes, called child nodes. You can display parent nodes, or nodes that contain child nodes, as expanded or collapsed. 阅读全文

摘要: Tabs attaches creates a tabbed interface from an unordered list of links/anchors that point to any elements on your page that have an id attribute. Since it attaches these behaviors to HTML that already has semantic meaning, it will degrade gracefully for browsers that do not support JavaScript, and is search engine friendly. It attaches in one line of code for simple use cases, but is highly customizable and can be used in a variety of edge cases. here we introduce the methods how can we creat 阅读全文
