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.

This book brings together indispensable knowledge for building efficient, high-value, Linux-based embedded products: information that has never been assembled in one place before. Drawing on years of experience as an embedded Linux consultant and field application engineer, Christopher Hallinan offers solutions for the specific technical issues you re most likely to face, demonstrates how to build an effective embedded Linux environment, and shows how to use it as productively as possible.

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
