In this letter, the error performance of an ultra-wideband (UWB) system with a hybrid pulse amplitude and Position modulation (PAPM) scheme over indoor lognormal fading channels is analyzed. In the PAPM UWB system, input data is modulated onto both the pulse amplitudes and pulse Positions.

1) Write a function reverse(A) which takes a matrix A of arbitrary dimensions as input and returns a matrix B consisting of the columns of A in reverse order. Thus for example, if A = 1 2 3 then B = 3 2 1 4 5 6 6 5 4 7 8 9 9 8 7 Write a main program to call reverse(A) for the matrix A = magic(5). Print to the screen both A and reverse(A). 2) Write a program which accepts an input k from the keyboard, and which prints out the smallest fibonacci number that is at least as large as k. The program should also print out its Position in the fibonacci sequence. Here is a sample of input and output: Enter k>0: 100 144 is the smallest fibonacci number greater than or equal to 100. It is the 12th fibonacci number.

HZK16文件是按照GB 2312-80標準，也就是通常所說的國標碼或區位碼的標準排列的。國標碼分為 94 個區(Section)，每個區 94 個位(Position），所以也稱為區位碼。其中01～09 區為符號、數字區，16～87 區為漢字區。而 10～15 區、88～94 區是空白區域。 如何取得漢字的區位碼呢？在計算機處理漢字和ASCII字符時，使每個ASCII字符占用1個字節，而一個漢字占用兩個字節，其值稱為漢字的內碼。其中第一個字節的值為區號加上32(20H)，第二個字節的值為位號加上32(20H)。為了與ASCII字符區別開，表示漢字的兩個字節的最高位都是1，也就是兩個字節的值都又加上了128(80H)。這樣，通過漢字的內碼，就可以計算出漢字的區位碼。

The PMSM FOC is made of several C modules, compatible with the free-of-charge IAR EWARM KickStart edition toolchain version 4.42. It is used to quickly evaluate both the MCU and the available tools. In addition, when used together with the STM32F103xx motor control starter kit (STM3210B-MCKIT) and PM motor, a motor can be made to run in a very short time. It also eliminates the need for time-consuming development of FOC and speed regulation algorithms by providing ready-to-use functions that let the user concentrate on the application layer. Moreover, it is possible to get rid of any speed sensor thanks to the sensorless algorithm for rotor Position reconstruction.

非常好的優化算法的書，詳細介紹了蟻群算法和粒子群算法以及相關的matlab工具箱，講了理論和應用給出了工具箱的下載地址。 Swarm intelligence is an innovative computational way to solve hard problems. In particular, particle swarm optimization, also commonly known as PSO, mimics the behavior of a swarm of insects or a school of fish. If one of the particle discovers a good path to food the rest of the swarm will be able to follow instantly even if they are far away in the swarm. Swarm behavior is modeled by particles in multidimensional space that have two characteristics: a Position and a velocity. These particles wander around the hyperspace and remember the best Position that they have discovered. They communicate good Positions to each other and adjust their own Position and velocity based on these good Positions.
