This is GPS Matlab findPreambles finds the first preamble occurrence in the bit stream of each channel. The preamble is verified by check of the spacing between preambles [6sec] and parity checking of the first two words in a subframe. At the same time function returns list of channels, that are in tracking state and with valid preambles in the nav data stream.

The Bit Array structure provides a compacted arrays of Booleans, with one bit for each Boolean value. A 0 [1] bit corresponds to the Boolean value false [true], respectively. We can look at a stream of bytes as a stream of bits each byte contains 8 bits, so any n bytes hold n*8 bits. And the operation to manipulate this stream or bits array is so easy, jut read or change the bits state or make any Boolean operation on the whole bits array, like 鈥楢ND鈥? 鈥極R鈥? or 鈥榅OR鈥?

The Kalman filter is a set of mathematical equations that provides an efficient computational [recursive] means to estimate the state of a process, in a way that minimizes the mean of the squared error. The filter is very powerful in several aspects: it supports estimations of past, present, and even future states, and it can do so even when the precise nature of the modeled system is unknown.

The main MIPS processor of SMP8630 comes with a JTAG interface, allowing: access to caches and data bus (DRAM) with a bandwidth of about 200kbit/s examining the processor state whatever the execution mode (monice) connecting to monice using mdi-server and using a gdb client on the processor to step and break accurately whatever the execution mode running semi-hosted applications fl ash write tool memory testing (MT command) real-time traces: has not been built in CPU (Config3_TL=0) and only supported by MajicPLUS probes (maybe built into emulator?)

(有源代码)数值分析作业,本文主要包括两个部分,第一部分是常微分方程(ODE)的三个实验题,第二部分是有关的拓展讨论,包括高阶常微分的求解和边值问题的求解(BVP).文中的算法和算例都是基于Matlab计算的.ODE问题从刚性(STIFFNESS)来看分为非刚性的问题和刚性的问题,刚性问题(如大系数的VDP方程)用通常的方法如ODE45来求解,效率会很低,用ODE15S等,则效率会高多了.而通常的非刚性问题,用ODE45来求解会有很好的效果.从阶次来看可以分为高阶微分方程和一阶常微分方程,高阶的微分方程一般可以化为状态空间(STATE SPACE)的低阶微分方程来求解.从微分方程的性态看来,主要是微分方程式一阶导系数大的时候,步长应该选得响应的小些.或者如果问题的性态不是太好估计的话,用较小的步长是比较好的,此外的话Adams多步法在小步长的时候效率比R-K(RUNGE-KUTTA)方法要好些,而精度也高些,但是稳定区间要小些.从初值和边值来看,也是显著的不同的.此外对于非线性常微分方程还有打靶法,胞映射方法等.而对于微分方程稳定性的研究,则诸如相平面图等也是不可缺少的工具.值得提出的是,除了用ode系类函数外,用simulink等等模块图来求解微分方程也是一种非常不错的方法,甚至是更有优势的方法(在应用的角度来说).

A Design and Implementation of The Online Shopping System Abstract: Along with the development of the computer ,the database technique is widespread in the application of Internet, more and more , providing more thoughtful and humanized service for the large network customer. Characteristic services have already become gradually the current as the application of Wed nowadays. This text studied a method of project which composed of characteristic page and dynamic state of technical customer according to the data connection rule, compared with some projects that adopt already on present nets, this project have the advantage of providing customers more simple ,reflective obvious meticulous use and so on..

This program incorporates the FV method for solving the Navier-Stokes equations using 2D, Cartesian grids and the staggered arrangement of variables. Variables are stored as 2D arrays. SIMPLE method is used for pressure calculation. UDS and CDS are implemented for the discretization of convective terms, CDS is used for the diffusive terms. The boundary conditions are set for the lid-driven cavity flow. Only steady flows are considered.

开发人员使用JavaScript的一个主要原因就是可以避免回发过程中带来的页面刷新。例如我们可以根据用户的需要使用Treeview控件来展开和折叠相应的数据节点。当你展开一个节点时，该Treeview控件将会利用JavaScript读取服务器上的子节点信息，然后平滑无刷新地插入这些新节点。如果没有使用JavaScript的话，Treeview控件将会因为页面的回发而重新构建。不但用户会发现因页面刷新而带来的延迟，而且页面极有可能回复到原来的状态，即丢失前面所展开的那些子节点信息。对于服务器端来说，因为每次回发的过程中都要处理大量的视图状态（View State）信息，这也会严重影响程序的整体执行性能。在ASP.NET 2.0中，引入了一个称为"客户端回调"的功能，利用这个内建的解决方案我们可以轻松实现客户端脚本和服务器端代码间的交互，从而避免了页面因回发带来的频繁刷新。

If you d like to know where visitors to your site live, add this to your feedback forms. They just choose a region, and the second menu changes appropriately, allowing them to choose their country. (If they choose USA, it allows them to select their state) Neat!
