摘要： Java Card technology is already a standard for smart cards and (U) SIM cards using an IC chip. Java Card technology has a problem related to slow execution speed of a program. It is also supports the transaction mechanism based on Flash memory to guarantee the integrity of data and a complete transaction during the execution of applets or downloading of applets. It is caused by too many Flash memory writing operations. In this paper, we have proposed a method to reduce the number of writing that new transaction mechanism in RAM memory.

摘要： Computational Grids deliver the necessary computational infrastructure to perform resource-intensive computations such as the ones that solve the problems scientists are facing today. Exploiting Computational Grids comes at the expense of explicitly adapting the ordinary software implementing scientific problems to take advantage of Grid resources, which unavoidably requires knowledge on Grid programming. The recent notion of "gridifying" ordinary applications, which is based on semi-automatically deriving a Grid-aware version from the compiled code of a sequential application, promises users to be relieved from the requirement of manual usage of Grid APIs within their source codes. In this paper, we describe a novel gridification tool that allows users to easily parallelize Java applications on Grids. Extensive experiments with two real-world applications - ray tracing and sequence alignment - suggest that our approach provides a convenient balance between ease of gridification and Grid resource exploitation compared to manually using Grid APIs for gridifying ordinary applications.

摘要： The authors use unified modelling language (UML) 2.0 interaction overview diagrams (IODs) and sequence diagrams to construct simple and expressive scenario-based specifications, and present an approach to runtime verification of Java programs for exceptional consistency and mandatory consistency. The exceptional consistency requires that any forbidden scenario described by a given IOD never happens during the execution of a program, and the mandatory consistency requires that if a reference scenario described by a given sequence diagram occurs during the execution of a program, it must immediately adhere to a scenario described by a given IOD. In the approach, the authors first instrument a program under verification so as to gather the program execution traces related to a given scenario-based specification; then they drive the instrumented program to execute for generating the program execution traces; finally they check if the collected program execution traces satisfy the given specification. The approach leads to a supporting tool for testing in which UML interaction models are used as automatic test oracles to detect the wrong temporal ordering of message interaction in programs.
