摘 要 瞬態(tài)仿真領域的許多工作需要獲得可視化數(shù)據(jù), 仿真電路不能將輸出參數(shù)繪制成圖形時研究工作將受到很大影響. 而權威電路仿真軟件PSpice 在這個方面不盡如人意. 本文提出了一種有效的解決辦法: 通過MATLAB 編程搭建一個PSpice 與MATLAB 的數(shù)據(jù)接口,使PSpice輸出數(shù)據(jù)文件可以導入到MATLAB中繪制圖形. 這令我們能夠很方便地獲得數(shù)據(jù)的規(guī)律以有效地分析仿真結果, 這項技術對于教學和工程實踐都有比較實際的幫助.關鍵詞: 瞬態(tài)仿真 仿真程序 PSpice MATLAB 可視化數(shù)據(jù)The Data Transfer from Pspice to MATLABWu hao Ning yuanzhong Liang yingAbstract Many works in the area of transient simulation has shown how a emulator such asPSpice can be interfaced to an control analysis package such as MATLAB to get viewdata.

Modern electronic systems solve so many difficult problems that they often seem like magic. Nonetheless, these systems all have thesame basic limitation: they need a source of electrical power! Most of the time this is a straightforward challenge for the electronicdesigner, because there are many power-delivery solutions. Yet sometimes a device has no direct power source, and running wiresor replacing batteries is impractical. Even when long-life batteries are usable, they eventually need to be replaced, which requires aservice call.

設計說明：1。數(shù)據(jù)結構和表示：程序用1、2、3、4分別表示將右、上、左、下的數(shù)字塊移動到空格之中。采用典型的樹+鏈表結構，每種局面產(chǎn)生一個BoardState類。出于避免走法順序列表被過多復制的考慮，在樹結構中保存局面的繼承關系。每種新的局面產(chǎn)生后，引用估值函數(shù)產(chǎn)生f的值，再根據(jù)大小將其插入鏈表之中，以便實現(xiàn)“優(yōu)先展開f值小的節(jié)點”。solve()函數(shù)在成功解決問題之后保存一個走法序列供輸出并返回零，而失敗則返回失敗處的節(jié)點層數(shù)。(具體的判斷方法見后文)

This model is just testing an idea of MIMO, which IEEE802.11n will have. But I havo not seen the standard, I tried to make it with 11a. Actually this model would not work in real world, because the preambles were not designed to solve the MIMO feature. But this model may be useful to get some idea to start to design a PHY with MIMO.

With the release of PHP 5 web developers need a guide to developing with PHP 5 to both learn its complex new features and more fully implement the long-standing features on which PHP s success is built. PHP 5 in Practice is a reference guide that provides developers with easy-to-use and easily extensible code to solve common PHP problems. It focuses on providing real code solutions to problems, allowing the reader to learn by seeing exactly what is happening behind the scenes to get your solution. Because a real-life situation will rarely match the book s example problems precisely, PHP 5 in Practice explains the solution well enough that you will understand it and can learn how to truly solve your own problem.

This paper presents an interactive technique that produces static hairstyles by generating individual hair strands of the desired shape and color, subject to the presence of gravity and collisions. A variety of hairstyles can be generated by adjusting the wisp parameters, while the deformation is solved efficiently, accounting for the effects of gravity and collisions. Wisps are generated employing statistical approaches. As for hair deformation, we propose a method which is based on physical simulation concepts but is simplified to efficiently solve the static shape of hair. On top of the statistical wisp model and the deformation solver, a constraint-based styler is proposed to model artificial features that oppose the natural flow of hair under gravity and hair elasticity, such as a hairpin. Our technique spans a wider range of human hairstyles than previously proposed methods, and the styles generated by this technique are fairly realistic.
