This is GPS Matlab acquisition code. Function performs cold start acquisition on the collected "data". It searches for GPS signals of all satellites, which are listed in field "acqSatelliteList" in the settings structure. Function saves code phase and frequency of the detected signals in the "acqResults" structure.

Introduction Matlab is an ideal tool for simulating digital communications systems, thanks to its easy scripting language and excellent data visualization capabilities. One of the most frequent simulation tasks in the field of digital communications is bit-error- rate testing of modems. The bit-error-rate performance of a receiver is a figure of merit that allows different designs to be compared in a fair manner. Performing bit-error-rate testing withMatlab is very simple, but does require some prerequisite knowledge.

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.

In an electromagnetic cloak based on a transformation approach, reduced sets of material properties are generally favored due to their easier implementation in reality, although a seemingly inevitable drawback of undesired reflection exists in such cloaks. Here we suggest using high-order transformations to create smooth moduli at the outer boundary of the cloak, therefore completely eliminating the detrimental scattering within the limit of geometric optics. We apply this scheme to a non-magnetic cylindrical cloak and demonstrate that the scattered field is reduced substantially in a cloak with optimal quadratic transformation as compared to its linear counterpart.

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

This book was intended specifically for people who know how to program already but have taken only rudimentary stabs at graphics/game programming or never taken any stab at all, such as programmers in another field or college students looking to embark on some side projects.
