Then, a multiobjective particle swarm optimization(MOPSO) is implemented to optimize the fuzzy controller parameters in order to decrease the distance error of the cart and summation of the angle errors of the pendulums, simultaneously. The feasibility and efficiency of the proposed Pareto front is assessed in comparison with results reported in literature and obtained from other algorithms.Finally, the Java programming with applets is utilized to simulate the stability of the nonlinear system and explain the internetbased control.展开更多

Here, several examples of Java programs are presented. These examples show some major features that Java language provides, such as multi-thread, exception handling, network application writing, and the usage of Java applets. This article also shows some ways of setting up a Java language programming environment. All these examples are correct and ready to run.展开更多

In this paper, a new slicing model is proposed to slice Java programs based on their inherent hierarchical feature. The main idea of hierarchical slicing is to slice programs in a stepwise way, from package level, to class level, method level, and finally up to statement level. The stepwise slicing algorithm and the related graph reachability algorithms are presented, the architecture of the Java program Analyzing TOol (JATO) based on hierarchical slicing model is provided, the applications and a small case study are also discussed.

This system grades submission both dynamically and statically to ensure a complete and through grading job. While dynamic analysis is based on JUnit framework, the static analysis is based on the graph representation of the program and its quality which is measured by software metrics. The graph representation is based on the Control Dependence Graphs (CDG) and Method Call Dependencies (MCD). eGrader outperforms existing systems in two ways: the ability of grading submission with semantic-errors, effectively, and generating reports for students, as a feedback on their performance, and instructors on the overall performance of the class. eGrader is well received by instructors not only for saving time and effort but also for its high success rate that is measured by four performance indicators which are sensitivity (97.37%), specificity (98.1%), precision (98.04%) and accuracy (97.07%).展开更多
