C 开发的有限元软件，界面还可以，不错，可以试试。 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.

密码学界牛人Victor Shoup用C++编写数论类库。 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.

签于目前市场上结合Query万能查询的第三方控件，适合DELPHI的特别多，如武稀松先生的WNQUERY，但适合CBUILDER的几乎是麟毛凤脚，由于公司产品上需要用到该功能，所以特别花了一天时间编了这个适合CBUILDER6版本的万能查询模块（如有需要亦可提供CBUILDER5的版本），供大家参考使用，改天有时间我会推出该系列的第三方控件，希望大家多提宝贵意见。 功能特点： 1、结合adoQuery（只适合adoQuery），如需支持Query，请另行通知我； 2、结合adoQuery->fields属性，查询条件可以根据fields的Visiable属性来定，也就是说fields->Field[0]->Visiable=false，这时你可以设置属性既可以把这类字段作为查询条件，也可以隐藏这类字段不作为查询条件显示； 3、根据字段类型显示比较值，举例说明：如果你选择的是DateTime字段，那比较值自动改为DateTimePicker，这比武稀松先生的WNQUERY要先进多了； 4、可以单项条件查询也可以多项条件结合查询； 上海同文信息技术有限公司 赵秀江（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.
