C programming is a craft that takes years to perfect. A reasonably sharp person can learn the basics of C quite quickly. But it takes much longer to master the nuances of the language and to write enough programs, and enough different programs, to become an expert. In natural language terms, this is the difference between being able to Order a cup of coffee in Paris, and (on the Metro) being able to tell anative Parisienne where to get off. This book is an advanced text on the ANSI C programming language. It is intended for people who are already writing C programs, and who want to quickly pick up some of the insights and techniques of experts.

Boost C++ Libraries Free peer-reviewed portable C++ source libraries Boost C++ Libraries 基本上是一個(gè)免費(fèi)的 C++ 的跨平臺(tái)函式庫集合，基本上應(yīng)該可以把它視為 C++ STL 的功能再延伸；他最大的特色在於他是一個(gè)經(jīng)過「同行評(píng)審」（peer review，可參考維基百科）、開放原始碼的函式庫，而且有許多 Boost 的函式庫是由 C++ 標(biāo)準(zhǔn)委員會(huì)的人開發(fā)的，同時(shí)部分函式庫的功能也已經(jīng)成為 C++ TR1 (Technical Report 1，參考維基百科)、TR2、或是 C++ 0x 的標(biāo)準(zhǔn)了。 它的官方網(wǎng)站是：http://www.boost.org/，包含了 104 個(gè)不同的 library；由於他提供的函式庫非常地多，的內(nèi)容也非常地多元，根據(jù)官方的分類，大致上可以分為下面這二十類： 字串和文字處理（String and text processing） 容器（Containers） Iterators 演算法（Algorithms） Function objects and higher-Order programming 泛型（Generic Programming） Template Metaprogramming Preprocessor Metaprogramming Concurrent Programming 數(shù)學(xué)與數(shù)字（Math and numerics） 正確性與測(cè)試（Correctness and testing） 資料結(jié)構(gòu)（Data structures） 影像處理（Image processing） 輸入、輸出（Input/Output） Inter-language support 記憶體（Memory） 語法分析（Parsing） 程式介面（Programming Interfaces） 其他雜項(xiàng) Broken compiler workarounds 其中每一個(gè)分類，又都包含了一個(gè)或多個(gè)函式庫，可以說是功能相當(dāng)豐富。

We introduce a sub-cell WENO reconstruction method to evaluate spatial derivatives in the high-Order ADER scheme. The basic idea in our reconstruction is to use only r stencils to reconstruct the point-wise values of solutions and spatial derivatives for the 2r-1 th Order ADER scheme in one dimension, while in two dimensions, the dimension-by-dimension sub-cell reconstruction approach for spatial derivatives is employed. Compared with the original ADER scheme of Toro and Titarev (2002) [2] that uses the direct derivatives of reconstructed polynomials for solutions to evaluate spatial derivatives, our method not only reduces greatly the computational costs of the ADER scheme on a given mesh, but also avoids possible numerical oscillations near discontinuities, as demonstrated by a number of one- and two-dimensional numerical tests. All these tests show that the 5th-Order ADER scheme based on our sub-cell reconstruction method achieves the desired accuracy, and is essentially non-oscillatory and computationally cheaper for problems with discontinuities.

最近在學(xué)習(xí)Oracle，對(duì)測(cè)試人員而言必須掌握兩種語言：第一種是DML，數(shù)據(jù)操縱語言 (Data Manipulation Language) 是SQL語言中，負(fù)責(zé)對(duì)數(shù)據(jù)庫對(duì)象運(yùn)行數(shù)據(jù)訪問工作的指令集，以INSERT、UPDATE、DELETE三種指令為核心，分別代表插入、更新與刪除。第二種是：DQL，數(shù)據(jù)查詢語言 (Data Query Language) 是SQL語言中，負(fù)責(zé)進(jìn)行數(shù)據(jù)查詢而不會(huì)對(duì)數(shù)據(jù)本身進(jìn)行修改的語句，這是最基本的SQL語句。核心指令為SELECT，以及一些輔助指令，如FROM、WHERE等，F(xiàn)ROM：表示來源，可以搭配JOIN做鏈接查詢； WHERE：過濾條件；GROUP BY：在使用聚合函數(shù)時(shí)用到，如SUM,COUNT,MAX,AVG；HAVING：對(duì)聚合結(jié)果進(jìn)行篩選，這是和WHERE的不同點(diǎn)；Order BY：排序。

This book addresses two aspects of network operation quality; namely, resource management and fault management. Network operation quality is among the functions to be fulfilled in Order to offer quality of service, QoS, to the end user. It is characterized by four parameters: – packet loss; – delay; – jitter, or the variation of delay over time; – availability. Resource management employs mechanisms that enable the first three parameters to be guaranteed or optimized. Fault management aims to ensure continuity of service.

In Order to improve the spectral efficiency in wireless communications, multiple antennas are employed at both transmitter and receiver sides, where the resulting system is referred to as the multiple-input multiple-output (MIMO) system. In MIMO systems, it is usually requiredto detect signals jointly as multiple signals are transmitted through multiple signal paths between the transmitter and the receiver. This joint detection becomes the MIMO detection.
