无线传感器网络的主要功能是实现数据发布,在接收到信息查询时能够以有效的方式传输给查询者.目前的数据发布方式通常基于洪泛机制查询信息,浪费了有限的能源.虽然一些最近的数据发布协议从不同程度上解决了这一问题,但不能保证查询成功率.基于圆形节点分布网络模型提出了一种既能减少能源消耗,又能提高成功率的数据发布模式——直径-弦模式DCS(diameter-chord scheme).该模式利用了每个圆的弦都存在一个直径与之垂直相交的性质.在此基础上提出了Two-Phase协议.它在信息查询时分成两个工作方式不同的阶段进行,在第1段查询不中时触发第2段查找.为了减少Two-Phase的延迟,提出了基于优先级和概率转发两种解决方法.理论分析和实验结果都表明,所提出的数据发布协议具有较好的性能.

ATViewer is a component for Delphi/C++Builder, which allows to view files of various types. There is no edit possibility, just quick view - so it s useful to implement "View file" feature in your Delphi/C++Builder application. The following view modes are implemented: Text, Binary, Hex, Unicode: all files, of unlimited size. Plain file dump is shown. Used ATBinHex component: only visible part of file is loaded into memory. Modes are suitable for huge files and files of unknown type. RTF/UTF-8: RTF and UTF-8 encoded texts. File is shown using RichEdit control. Image: all general image formats: BMP JPG ICO GIF PNG... File is shown using ATImageBox component. Multimedia: all file types supported by MS Windows Media Player: AVI MPEG WMV MP3... File is shown using WMP ActiveX control. Internet: all file types supported by MS Internet Explorer: HTML XML DOC XLS... File is shown using MSIE ActiveX control. Plugins: all files supported by Total Commander Lister plugins.

Welcome to Beginning Algorithms, a step-by-step introduction to computing algorithms for the real world. Developers use algorithms and data structures every day of their working lives. Having a good understanding of these algorithms and knowledge of when to apply them is essential to producing software that not only works correctly, but also performs efficiently. This book aims to explain those algorithms and data structures most commonly encountered in day-today software development, while remaining at all times practical, concise, and to the point, with little or no verbiage to distract from the core concepts and examples.

The control uses javascript to handle number formatting as you keep typing and does the validation as well. For one of our requirement, we needed a javascript based control that did formatting as the users kept typing. Google search only yielded script that did formatting on focus change events only. So I went about creating a new control myself.

Addfilter is a command-line application which adds and removes filter drivers for a given drive or volume. It is intended to demonstrate how to insert a filter driver into the driver stack of a device. The sample illustrates how to do this by using the SetupDi APIs. The sample works on the x86 platform. It has only been tested in a 32-bit environment. Since Addfilter is not a driver, it does not deal with Plug and Play or Power Management.

Accurate estimates of the autocorrelation or power spectrum can be obtained with a parametric model (AR, MA or ARMA). With automatic inference, not only the model parameters but also the model structure are determined from the data. It is assumed that the ARMASA toolbox is presen
