摘要： The medical industry has taken advantage of Java and Java technologies over the past few years, in large part due to the language's platform-independence and object-oriented structure. As such, Java provides powerful and effective toots for developing tissue section analysis software. The background and execution of this development are discussed in this publication. Object-oriented structure allows for the creation of "Slide", "Unit", and "Cell" objects to simulate the corresponding reat-world objects. Different functions may then be created to perform various tasks on these objects, thus facilitating the development of the software package as a whole. At the current time, substantial parts of the initially planned functionality have been implemented. Getafics 1.0((R)) is fully operational and currently supports a variety of research projects;however, there are certain features of the software that currently introduce unnecessary complexity and inefficiency. In the future, we hope to include features that obviate these problems. (C) 2004 Elsevier Ireland Ltd. All rights reserved.

摘要： The paper describes an experiment in which a framework for model checking Java byte code, combined with the application of runtime monitoring techniques through code rewriting, was used to guarantee correctness properties of a Java Card applet.

关键词： Java   Memory management   Run-time analysis   Real-time and embedded systems  

摘要： We present a method to analyze, monitor and control dynamic memory allocation in Java. It first consists in performing pointer and escape analysis to detect memory scopes. This information is used to automatically instrument Java programs in such a way memory is allocated and freed by a region-based memory manager. Our source code instrumentation fully exploits the result of scope analysis by dynamically mapping allocation places to the region stack at runtime via a registering mechanism. Moreover, it allows executing the same transformed program with different implementations of scoped-memory managers and perform different run-time analysis without changing the transformed code. In particular, we consider a class of managers that handle variable-size regions composed of fixed-size memory blocks for which we provide analytical models for the intra-and inter-region fragmentation. These models can be used to observe and control fragmentation at run-time with negligible overhead. We describe a prototype tool that implements our approach.

关键词： 并发程序   程序分析   escape分析   同步删除  

摘要： 同步操作是并发Java程序非常大的一部分开销.在现有程序分析方法的基础上,提出了一种精确而有效的冗余同步操作的静态删除方法.该方法分为基本处理和线程间时序分析两个阶段,充分考虑了控制流结构和线程交互时序对同步删除的影响.构造了一个Java编译器JTool,并在其上实现了同步删除算法.对于确定的单线程程序,同步删除率达到100%;对于多线程程序,同步删除率高于现有的分析工具.

摘要： 问题的产生：在编写网站的JSP页面中使用了JSP的页面指示符<％@include％>，目的是为了让网站中的页面具有统一风格的外观，即每一个页面的开头部分是相同的。

关键词： Java语言   MVC   EJB   程序开发  

摘要： 在Java中MVC和EJB是两个流行的开发模式,当然它们的难度也是可想而知的。文章中 利用一个经典的Hello World的例子(具备MVC和EJD的基本特征),力图用简单易懂的方式, 展示怎样将这两种开发模式结合起来,希望给Java入门者一点帮助。

关键词： Java   algorithms   VSIPL   spectral estimation  

摘要： This paper examines the capability, performance, and relevance of a high-performance advanced signal processing toolkit in Java, a programming language for Web-based applications. To demonstrate the simplicity, ease, and application use of the toolkit, a spectral estimation applet has been developed in the Java environment using advanced Internet technologies such as Remote Method Invocation (RMI). This application provides an interactive and visual approach in understanding theoretical concepts of advanced signal processing methods and shows the need to create more application applets to better understand additional concepts in signal and image processing. Furthermore, a toolkit with limited functionality and different framework has been developed for embedded and handheld devices such as cellular phones and palm pilots. This toolkit is also shown to be useful in developing applications MIDlets on those devices. (C) 2004 Elsevier B.V. All rights reserved.
