The design scheme and key technologies of remote tax declaration system (RTDS) is proposed in this paper. Especially, it is presented that how to apply XML to deal with heterogeneous data source, how to make use of the PKI and DES algorithms to improve the efficiency of encryption, and how to solve the concurrency of clients in RTDS by using Java threads. Finally, the experiment results are shown...
With the development of multicore-processor, the parallel computer system are gaining a rapid progress from supercomputer to personal computer. But the knowledge on parallel computing is seldom involved in the traditional undergraduate stage of computer specialty. Under the current situation, it is very necessary to set the parallel computing as an independent course in the teaching plan of computer...
Java programming is an important and basic specialized course for students of computer specialty in higher vocational colleges. In addition, object orientation programming is currently widespread programming method. In this paper, basing on the characteristic of Java programming and our practical teaching experiences, we proposed many measures how to improve the teaching quality.
We know that the statistical properties of random number generator with single chaos mapping have some shortcomings of unsatisfactory statistical performances. In this paper we propose a combined random number generator with uniform distribution, which is composed of non-linear chaotic Logistic mapping, hybrid optical chaotic mapping and linear congruential method. Experiment results demonstrate that...
