Integrated EMI/Thermal Design forSwitching Power SuppliesWei ZhangThesis submitted to the Faculty of theVirginia Polytechnic Institute and State Universityin partial fulfillment of the requirements for the degree of Integrated EMI/Thermal Design forSwitching Power SuppliesWei Zhang(ABSTRACT)This work presents the modeling and analysis of EMI and thermal performancefor switch power supply by using the CAD tools. The methodology and design guidelinesare developed.By using a boost PFC circuit as an example, an equivalent circuit model is builtfor EMI noise prediction and analysis. The parasitic elements of circuit layout andcomponents are extracted analytically or by using CAD tools. Based on the model, circuitlayout and magnetic component design are modified to minimize circuit EMI. EMI filtercan be designed at an early stage without prototype implementation.In the second part, thermal analyses are conducted for the circuit by using thesoftware Flotherm, which includes the mechanism of conduction, convection andradiation. Thermal models are built for the components. Thermal performance of thecircuit and the temperature profile of components are predicted. Improved thermalmanagement and winding arrangement are investigated to reduce temperature.In the third part, several circuit layouts and inductor design examples are checkedfrom both the EMI and thermal point of view. Insightful information is obtained.

Apriori算法源碼（C++） 看了以前在這里發(fā)的apriori源碼，覺得寫得代碼有些繁瑣，現(xiàn)在重寫了一下，主要是把數(shù)據(jù)操作和界面顯示分離，使用了stl和boost，簡(jiǎn)化了字符操作的算法，數(shù)據(jù)庫用的是mysql的，API是mysql++,在mfc下mysql++無法運(yùn)行，所以gui框架用的是win32gui-lib(可以到sf.net/project/win32gui下載)。當(dāng)然你也可以用odbc改寫，或是換用別的數(shù)據(jù)庫，因?yàn)樗惴ㄟ壿嬍仟?dú)立的，所以應(yīng)該很容易改寫

This collection of C++ templates wraps the FORTRAN or C interfaces for LAPACK so that they integrate with the Boost uBLAS library. Currently implements Cholesky decomposition, LU decomposition, inversion and determinant for general and positive-definite matrices.

Recite(一個(gè)輔助英語學(xué)習(xí)軟件源碼) 該程序的UI部分使用了WTL7.5。WTL7.5可以很容易的在微軟的官方網(wǎng)站找到，安裝也很簡(jiǎn)單。 另外使用了BOOST庫中的部分內(nèi)容。包括filesystem用于操作文件名和目錄，可以在（ http://lunatic.bokee.com/5899788.html ）找到更詳細(xì)的介紹。serialization用于將對(duì)象序列化在磁盤文件中。datetime用于做日期的計(jì)算。還用到了string algo做簡(jiǎn)單的字符串操作。因此你需要從（ http://www.boost.org ）下載boost的最新版本1.33.1，并在本地編譯它。 配置文件的讀寫使用了TinyXML，源碼已經(jīng)包含在源碼包中，無須另外下載。 整個(gè)程序的祼奔性相當(dāng)好，不依賴于其他任何的DLL或COM庫，就一個(gè)EXE文件。 我的編程和調(diào)試環(huán)境為WindowsXP，Visual Studio .net 2003。 該軟件的目的及作用請(qǐng)參見（ http://lunatic.bokee.com/6153131.html ） 使用方法（ http://lunatic.bokee.com/6153160.html ） 相關(guān)的資源（ http://lunatic.bokee.com/6153181.html ）

此書名為超越C++標(biāo)準(zhǔn)程序庫，是的，它講述的正是boost庫（boost庫可是未來c++的標(biāo)準(zhǔn)方向喲，掌握了boost就是掌握了未來的c++）。包含了各個(gè)庫的功能的詳細(xì)介紹以及列舉的例子。總的包含通用庫、容器及數(shù)據(jù)結(jié)構(gòu)、函數(shù)對(duì)象及高級(jí)編程幾個(gè)大的部分，內(nèi)部又有很多小的部分。

If you re like me, you re excited by what people do with template metaprogramming (TMP) but are frustrated at the lack of clear guidance and powerful tools. Well, this is the book we ve been waiting for. With help from the excellent Boost Metaprogramming Library, David and Aleksey take TMP from the laboratory to the workplace with readable prose and practical examples, showing that "compile-time STL" is as able as its runtime counterpart. Serving as a tutorial as well as a handbook for experts, this is the book on C++ template metaprogramming."Chuck Allison, Editor, The C++ Source
