[Industry research] [10]Minimum_cost_configuration_of_relay_and_chann DL : 0: Fixed broadband wireless access is a promising technology allowing Internet service providers to expend their customer base in sparsely populated rural areas. Because the size of the target service area is humongous, relay in- frastructure is essential. Installing and maintaining this relay infrastructure is the main cost associated with such networks. Thus, we develop an optimization framework which computes the minimum number of relay stations and their cor- responding channel conﬁ gurations such that a pre-speciﬁ ed subscribers’ trafﬁ c demand can be satisﬁ ed. Since the problem is a mixed-integer program, we pro- pose an efﬁ cient optimization algorithm to compute the optimal solution in a reasonable amount of time. Our numerical results show that by using a few relay stations in a rural community, broadband Internet access can be established in a cost effective manner.

[Industry research] rtklib_2.4.1 DL : 1: rtklib 版本2.4.1 An Open Source Program Package for GNSS Positioning 日本开源网站上提供的关于GPS卫星数据解算的程序。All of the executable binary APs for Windows are included in the package as well as whole source programs of the library and the APs. * For real-time PPP, EUREF and IGS have already started to distribute real-time satellite orbit and clock as RTCM v.3 SSR messages via NTRIP. To receive the real-time satellite orbit and clock, users have to make registration and get an account to access the NTRIP broadcasters. Refer BKG GDC site http://igs.bkg.bund.de/ntrip/index for details. -All of the library functions and APIs are written in ANSI C (C89). The library internally uses standard socket and pthread for Linux/UNIX or winsock and WIN32 thread for Windows. By setting compiler option-DLAPACK or-DMKL, the library uses LAPACK/BLAS or Intel MKL for fast matrix computation. The console APs are also written in standard C. The library and console APs can be built on many environments like gcc on Linux. The GUI APs are written in C++ and utilize Borland VCL for the GUI toolkit. All of the executable binary APs in the package were built by free edition Borland Turbo C++ 2006 (http://www.turboexplorer.com)* on Windows. The binary APs were tested on Windows XP SP3 32bit and Windows 7 SP1 64bit. The console APs are also built and tested on Ubuntu 9.04 Linux.

[Industry research] webv8 DL : 0: 安易王V8是使用新一代科技开发的纯WEB版财务及ERP管理软件，具有B/S结构的免安装，易维护，移动互联的特点外。还有具有普通WEB版软件没有的特点。一是页面不用刷新。二是所有操作方便，与桌面安装程序操作极其相像。三是数据进行压缩传输，比普通C/S结构的远程系统取代码要快100倍左右，比远程桌面方式的远程系统要快十倍左右，比传统的WEB版B/S结构程序要快15倍左右。四是解决了WEB版的打印难题，是传统的B/S系统不能比拟的。演示及下载地址：http://www.anyi.net.cn/v8.html 联系QQ:377475957-An easy king V8 is a new generation of technology development using pure WEB version of financial and ERP management software, with B/S structure of the free installation, easy maintenance, to the characteristics of mobile Internet. WEB version of the software also has no common characteristics. One page is not refreshed. Second, all easy to operate, with the desktop installer operation is extremely similar. Third, data compression and transmission, than ordinary C/S structure of the remote system access code is about 100 times faster than remote desktop-based remote system is about ten times faster than conventional WEB version of B/S structure of the program to be fast 15 times. Fourth, to solve the WEB version of the print problem, is a traditional B/S system can not match. Demo and Download: http://www.anyi.net.cn/v8.html Contact QQ: 377475957
