从高斯-牛顿迭代的角度对迭代扩展卡尔曼滤波(IEKF)进行分析,提出了一种基于组合牛顿迭代法的改进IEKF算法。该算法通过实时判断每次迭代对状态的逼近程度,采用加权平均的方法确定新的迭代值,继而采用卡尔曼滤波框架对状态进行量测更新。新算法较传统的IEKF具有精度高以及对初值不敏感的优点。实例仿真验证了该算法的有效性。

ComponentOne 2012 V2 Studio for Silverlight 文件名称：C1Silverlight_2012v2.msi 60+ powerful, yet lightweight, controls offer the latest Web UI trends and take advantage of everything Silverlight 5 has to offer. Silverlight UI Controls with Power and Style Get the controls and features you need to develop compelling applications and dashboards with ease. ComponentOne Studio® for Silverlight is a suite of 60+ controls built on Microsoft® Silverlight®. These powerful, yet lightweight, controls offer the latest Web UI trends and take advantage of everything Silverlight 5 has to offer from rich media to business application development. What's Inside? § Chart § DataGrid § FlexGrid § Maps § RichTextBox § Scheduler § § § § § § § § § § § § § § § § § § § § § § § § § § § § § § § § § § § § § § § § § § § Show More Why Choose Studio for Silverlight? § Professional Themes and Simple Styling Get 12+ themes including Metro, Office and Expression for the entire studio. Plus, with built-in ClearStyle technology, you can easily change control colors without having to modify complex templates. By just setting a few brush properties in Visual Studio you can quickly give a unique look to any C1 control without having to work in Expression Blend or be a professional designer. § Stunning and Powerful Data Visualization With 40+ chart types, flexible data binding, run-time interaction, optimization for large data sets, and so much more, Chart for Silverlight is the most advanced charting control on the market. Apply styles, animations, markers and live updates to bring your dashboards to life! § Maps Powered By Esri When it comes to mapping, we have you covered. ComponentOne has partnered with Esri, the leading online map and GIS provider, to bring you the best mapping tools and UI controls together in one package. Easily transform GIS data into business intelligence with Maps powered by Esri®. With Studio for Silverlight you get free access to to the Esri controls, online map tiles and the ArcGIS API for Silverlight. § Fast and Flexible FlexGrid Experience the FlexGrid's legendary flexibility, speed, and small footprint. Inspired by Microsoft Excel for creating bound and unbound grids and scrolling speed 10x faster than the competition, FlexGrid for Silverlight provides built-in printing, cell merging, column aggregation, custom cells, and all the extensibility you need for your business data. § HTML and PDF Support Get first-class support for HTML and PDF content in Silverlight with many of the ComponentOne controls. View your PDF documents and HTML reports using the innovative PdfViewer and ReportViewer controls. Deliver complete HTML editing with the Microsoft Word-like RichTextBox control. Export your data to PDF with ease using the C1Pdf class library. § Built-in Localization Broaden your global audience with quick localization support for 20+ international languages. Studio for WPF includes the necessary resource files for localizing your apps so you can publish in Arabic, Chinese (General, Simplified and Traditional), Czech, Danish, English, German, Greek, Finnish, French, Hebrew, Italian, Japanese, Dutch, Norwegian, Polish, Portuguese, Russian, Slovak, Spanish and Swedish. § MVVM Support Use the latest presentation model or MVVM (Model-View-ViewModel) design patterns in your applications with ComponentOne Silverlight and WPF controls. Each control supports dependency properties, complete XAML configuration and WPF data-binding techniques. § Write Once Deploy Everywhere Studio for Silverlight controls share the same codebase as our WPF controls and Windows Phone controls. So you can build rich web, mobile and desktop client applications while sharing a lot of the same code. This will reduce development time, cost and eliminate the learning curve of having to learn controls from multiple platforms. You can also use your XAML skills to develop LightSwitch extensions and SharePoint Web Parts using our controls. See our Studio for SharePoint and OLAP for LightSwitch as examples.

准确认定贫困生资格,是高校公平、公正、合理分配国家资助资源的先决条件.将数据挖掘的决策树方法引入高校贫困生资格认证分析中,利用C4.5算法创建决策树,挖掘学生信息和贫困种类关系的历史数据,建立学生信息―贫困种类智能评价模型.通过实验仿真发现,C4.5决策树算法取得了较为理想的分类预测效果.

浅海环境中,海底地形复杂且散射强度大,加之波导效应明显,因此有效地掌握浅海低频海底混响的空间分布特性对工作在浅海的主动远程探测系统极为重要.以耦合简正波理论为出发点,把海底混响视为界面不规则起伏对入射声场的耦合作用所致.依据浅海混响的耦合简正波模型,分别计算了远程海底混响的垂向、水平纵向、水平横向相关性随收发位置、时间和频率的变化关系.利用实验数据验证了该理论得到的垂向相关的计算结果,并通过理论仿真比较了垂向、水平纵向、水平横向的相关特性.研究结果表明,对于低频远程海底混响水平横向相关大于水平纵向相关,垂

基于小波分析理论和概率统计原理，提出一种损伤存在概率成像方法，对复合材料结构进行在线的健康监测。首先对结构损伤前后Lamb信号进行比较，提取信号的能量特征差异系数，作为损伤指标；然后用概率统计方法判断该损伤指标是由损伤引起的还是因环境变化造成的；最后用成像算法给出存在概率图像识别损伤。对复合材料板结构进行实验验证该方法的可行性，具有一定的实际工程应用价值。
