VSCF
变速恒频风力发电技术风力发电具有一些自身所拥有的特点,因此如何提高整个风力发电系统的效率、性能以及其输出电能质量,是当今风力发电研究的重点也是风力发电研究的发展方向。目前已有的风力发电技术主要有四类:定桨距调节技术、变桨距调节技术、主动失速调剂技术、变速恒频技术。因定桨距调节技术产生的时间比较早,并且现在的风力发电系统中不再使用因此不做详细介绍。(VSCF wind power generation technology)

Locally-Laplace-Isometries
发表在 The MIT Talbot 2013 Workshop 的论文 (Locally Laplace Isometries and Fibonacci Primes. this paper shows that there exists a reversible, unique and separable elliptic, Brahmagupta arrow. In this setting, the ability to study positive scalars is essential. Recent interest in partially ultra-positive domains has centered on deriving Pythagoras{Wiles scalars.)

说明: 超紧耦合是 GPS/INS 组合导航系统的最新研究方向,它采用 INS 测得的载体动态信息辅助 GPS 接收机跟踪环
路,消除卫星信号中由于载体与卫星之间相对运动所产生的频率偏移,提高接收机在高动态环境下载波跟踪性能,同时还
可以压缩带宽,有效增强接收机抗干扰性能。介绍 GPS/INS 超紧耦合技术,给出 INS 辅助 GPS 载波跟踪环路结构图和相应
的数学模型,分析 INS 辅助 GPS 跟踪环路在动态环境下的动态残留及其对环路相位误差的影响,并进行了模型仿真,最后
对仿真结果进行了验证分析。仿真结果显示,辅助动态残留及其导致的环路相位误差的大小与加加速度、环路辅助时间间
隔成正比。
(The ultra-tightly coupled GPS/INS integrated navigation system latest research direction, it adopted the INS measured the carrier dynamic information auxiliary GPS receiver tracking loop to eliminate the satellite signal frequency due to the relative motion between the carrier and the satellite offset improve the receiver in high dynamic environment download wave tracking performance, but also can compress bandwidth, effectively enhance the anti-jamming performance of the receiver. Introduced GPS/INS ultra-tight coupling technology gives INS assisted GPS carrier tracking loop diagram and the corresponding mathematical model to analyze the impact of the INS assisted GPS tracking loop dynamic residues in a dynamic environment and the loop phase error, and model simulation, and analysis of simulation results verified. Simulation results show that the the residual secondary dynamic its resulting size of the error loop phase and jerk loop secondary is proportional to the time interval.)

rtklib_2.4.1
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.
