两台处理机A 和B处理n个作业。设第i个作业交给机器 A 处理时需要时间ai，若由机器B 来处理，则需要时间bi。由于各作 业的特点和机器的性能关系，很可能对于某些i，有ai >=bi，而对于 某些j，j!=i，有aj<bj。既不能将一个作业分开由两台机器处理，也没 有一台机器能同时处理2 个作业。设计一个动态规划算法，使得这两 台机器 ...

加密的步骤 1) 计算N的有效位数tn（以字节数计），将最高位的零忽略掉，令tn1＝tn－1。比如N＝0x012A05，其有效位数tn＝5，tn1＝4。 2) 将明文数据A分割成tn1位（以字节数计）的块，每块看成一个大数，块数记为bn。从而，保证了每块都小于N。 3) 对A的每一块Ai进行Bi＝Ai^E MOD N运算。Bi就是密文数据的一块，将所有密文 ...

The double-density DWT is an improvement upon the critically sampled DWT with important additional properties: (1) It employs one scaling function and two distinct wavelets, which are designed to be offset from one another by one half, (2) The double-density DWT is overcomplete by a factor of two, a ...

A paper that I presented on Supervisory Control and Data Acquisition (SCADA) won the second prize at the symposium conducted by the Electrical and Electronics Engineering department of the SRM University. Other topics on which I presented papers were Performance enhancement of wireless sensor networ ...

PSO’s precursor was a simulator of social behavior, that was used to visualize the movement of a birds’ flock. Several versions of the simulation model were developed, incorporating concepts such as nearest-neighbor velocity matching and acceleration by distance

The radially averaged power spectrum (RAPS) is the direction-independent mean spectrum, i.e. the average of all possible directional power spectra. This function computes and plots the RAPS of an input image. The function was written to produce the RAPS for square weather radar reflectivity images s ...
