This paper investigates the possibility of using Java as a language for Digital Signal Processing. We compare the performance of the Fast Fourier Transform using Java interpreters, compilers, and native execution. To characterize the Java language as a platform for signal processing, we have implemented a traditional FFT algorithm in both C and Java and compared their relative performance. Addi...

jMonitor is a pure Java library and runtime utility for specifying event patterns and associating them with user provided event monitors that get called when the specified Java runtime events occur during the execution of legacy Java applications. jMonitor APIs define an event specification abstraction layer allowing programmers to design event patterns they would like to monitor during the run...

This paper describes how multi-agent system technology can be used as the underpinning platform for voltage control in power systems. In this study, some FACTS (flexible AC transmission systems) devices are properly designed to coordinate their decisions and actions in order to provide a coordinated secondary voltage control mechanism based on multi-agent theory. Each device here is modeled as ...

The Java programming language has been widely used to develop dynamic content in Web pages. The Java Virtual Machine (JVM) executes Java bytecode. For efficient transmission over the Internet, the Java bytecode is a stack oriented architecture: instructions need not contain source and destination specifiers in their bytecodes. The Java bytecodes may be executed on various platforms by interpret...

INTRODUCTION Why should Java security concern you? Many push-based applications are being ported to Java. In addition, Java is one of the cornerstones of active content and an understanding of Java security basics is necessary for understanding the implications of push security issues. A lot of people ask: “Why do I need Java security? I thought it was safe.” Java as a language is basically saf...

Many software developers are using the Java language as the language of choice on many applications. This is due to the effective use of the object-oriented (OO) paradigm to develop large software projects and the ability of the Java language to support the increasing use of web technologies in business applications. The recent release of the Java version 5.0 has further increased its popularit...

A number of Java environments run untrusted services as Java threads. However, Java threads may not be suitably secure for this task because of its problem with safe termination, resource control and thread isolation. These problem areas have been recognised by the research community and are comprehensively addressed in the not yet implemented Java Isolate API. Meanwhile, Java threads continue ...

SUMMARY The Java™ Native Interface (JNI) provides a set of mechanisms for implementing Java methods in C or C++. JNI is useful for reusing C and C++ code repositories within Java frameworks. JNI is also useful for real-time systems, where compiled C/C++ code executes performance-critical tasks, while Java code executes system control and feature tasks. Available JNI literature concentrates on c...

Title of Thesis: A RETARGETABLE OPTIMIZING JAVA-TO-C COMPILER FOR EMBEDDED SYSTEMS Ankush Varma, M.S., 2003 Thesis directed by: Professor Shuvra S. Bhattacharyya Department of Electrical and Computer Engineering The Java programming language is achieving greater acceptance in high-end embedded systems such as cellphones and PDAs. However, lowend embedded platforms, such as DSPs or microcontroll...
