题目：取一个整数a从右端开始的4～7位。 程序分析：可以这样考虑： (1)先使a右移4位。 (2)设置一个低4位全为1,其余全为0的数。可用~(~0<<4) (3)将上面二者进行&运算。 2.程序源代码：(Topic: take an integer a from the right end of the four to seven began. Program analysis: it can be to consider: (1) to make a move to the right four. (2) sets a low four total for the 1, all the rest for 0 of the number. Can be used to (~ 0 < < 4) (3) will above the difference and operations. 2. The source code:)

1. 实现图书馆对外借书,还书的简易操作，提高图书馆对最平凡工作的效率。 2. 实现图书馆对所藏图书的按类别，书名等多方面的查询，最大的方便读者和图书馆工作人员对所需图书的查询。 3. 建立图书馆外借读者数据库，方便工作人员对读者进行有效管理。 4. 建立图书馆工作人员数据库，限定每个工作人员对软件操作的权限，最大限度的保护数据库。 5. 实现图书馆对新书入库，旧书注销的简单处理，并且建立书籍档案，方便进货。 (1. 实现图书馆对外借书,还书的简易操作，提高图书馆对最平凡工作的效率。 2. 实现图书馆对所藏图书的按类别，书名等多方面的查询，最大的方便读者和图书馆工作人员对所需图书的查询。 3. 建立图书馆外借读者数据库，方便工作人员对读者进行有效管理。 4. 建立图书馆工作人员数据库，限定每个工作人员对软件操作的权限，最大限度的保护数据库。 5. 实现图书馆对新书入库，旧书注销的简单处理，并且建立书籍档案，方便进货。)

This Paper mainly deals with the implementation of vector control technique using the brushless DC motor (BLDC). Generally tachogenerators, resolvers or incremental encoders are used to detect the speed. These sensors require careful mounting and alignment, and special attention is required with electrical noises. A speed sensor need additional space for mounting and maintenance and hence increases the cost and size of the drive system. These problems are eliminated by speed sensor less vector control by using Extended Kalman Filter and Back EMF method for position sensing. By using the EKF method and Back EMF method, the sensor less vector control of BLDC is implemented and its simulation using MATLAB/SIMULINK and hardware kit is implemented.

poj 3941 Hideyuki is allowed by his father Ujisato some 1000 yen bills every month for his pocket money. In the first day of every month, the number of bills is decided as follows. Ujisato prepares n pieces of m-sided dice and declares the cutback k. Hideyuki rolls these dice. The number of bills given is the sum of the spots of the rolled dice decreased by the cutback. Fortunately to Hideyuki, Ujisato promises him to give at least one bill, even if the sum of the spots does not exceed the cutback. Each of the dice has spots of 1 through m inclusive on each side, and the probability of each side is the same. In this problem, you are asked to write a program that finds the expected value of the number of given bills.
