C 開發的有限元軟件，界面還可以，不錯，可以試試。 FElt is a free system for introductory level finite element analysis. It is primarily intended as a teaching tool for introductory type courses in finite elements - probably in the mechanical/structural/civil Fields. In a command line environment, FElt uses an intuitive, straightforward input syntax to describe problems. It also includes a graphical user interface for workstations that allows the user to set-up, solve and post-process the problem in a single CAD-like environment.

密碼學界牛人Victor Shoup用C++編寫數論類庫。 NTL is a high-performance, portable C++ library providing data structures and algorithms for arbitrary length integers for vectors, matrices, and polynomials over the integers and over finite Fields and for arbitrary precision floating point arithmetic. NTL provides high quality implementations of state-of-the-art algorithms for: * arbitrary length integer arithmetic and arbitrary precision floating point arithmetic * polynomial arithmetic over the integers and finite Fields including basic arithmetic, polynomial factorization, irreducibility testing, computation of minimal polynomials, traces, norms, and more * lattice basis reduction, including very robust and fast implementations of Schnorr-Euchner, block Korkin-Zolotarev reduction, and the new Schnorr-Horner pruning heuristic for block Korkin-Zolotarev * basic linear algebra over the integers, finite Fields, and arbitrary precision floating point numbers.

We analyze, both analytically and numerically, the effectiveness of cloaking an infinite cylinder from observations by electromagnetic waves in three dimensions. We show that, as truncated approximations of the ideal permittivity and permeability tensors tend towards the singular ideal cloaking Fields, so that the anisotropy ratio tends to infinity, the D and B Fields blow up near the cloaking surface. Since the metamaterials used to implement cloaking are based on effective medium theory, the resulting large variation in D and B will pose a challenge to the suitability of the field averaged characterization of " and 碌. We also consider cloaking with and without the SHS (softand- hard surface) lining, shown in [6] to be theoretically necessary for cloaking in the cylindrical geometry. We demonstrate numerically that cloaking is significantly improved by the SHS lining, with both the far field of the scattered wave significantly reduced and the blow up of D and B prevented.

簽于目前市場上結合Query萬能查詢的第三方控件，適合DELPHI的特別多，如武稀松先生的WNQUERY，但適合CBUILDER的幾乎是麟毛鳳腳，由于公司產品上需要用到該功能，所以特別花了一天時間編了這個適合CBUILDER6版本的萬能查詢模塊（如有需要亦可提供CBUILDER5的版本），供大家參考使用，改天有時間我會推出該系列的第三方控件，希望大家多提寶貴意見。 功能特點： 1、結合adoQuery（只適合adoQuery），如需支持Query，請另行通知我； 2、結合adoQuery->Fields屬性，查詢條件可以根據Fields的Visiable屬性來定，也就是說Fields->Field[0]->Visiable=false，這時你可以設置屬性既可以把這類字段作為查詢條件，也可以隱藏這類字段不作為查詢條件顯示； 3、根據字段類型顯示比較值，舉例說明：如果你選擇的是DateTime字段，那比較值自動改為DateTimePicker，這比武稀松先生的WNQUERY要先進多了； 4、可以單項條件查詢也可以多項條件結合查詢； 上海同文信息技術有限公司 趙秀江（David） http://www.twsoft.cn Email：mail@twsoft.cn david@twsoft.cn MSN：twsoft@hotmail.com QQ：5281034

Text mining tries to solve the crisis of information overload by combining techniques from data mining, machine learning, natural language processing, information retrieval, and knowledge management. In addition to providing an in-depth examination of core text mining and link detection algorithms and operations, this book examines advanced pre-processing techniques, knowledge representation considerations, and visualization approaches. Finally, it explores current real-world, mission-critical applications of text mining and link detection in such varied Fields as M&A business intelligence, genomics research and counter-terrorism activities.

This book is about 3D math, the study of the mathematics behind the geometry of a 3D world. 3D math is related to computational geometry, which deals with solving geometric problems algorithmically. 3D math and computational geometry have applications in a wide variety of Fields that use computers to model or reason about the world in 3D, such as graphics, games, simulation, robotics, virtual reality, and cinematography. This book covers theory and practice in C++.
