The concept of nanopublications was first proposed about six years ago, but it lacked openly available implementations. The library presented here is the first one that has become an official implementation of the nanopublication community. Its core features are stable, but it also contains unofficial and experimental extensions: for publishing to a decentralized server network, for defining se...

In recent years Java has matured to a stable easy-to-use language with the flexibility of an interpreter (for reflection etc.) but the performance and type checking of a compiled language. When we started using Java for astronomical applications around 1999 they were the first of their kind in astronomy. Now a great deal of astronomy software is written in Java as are many business applications...

The programming language Java has made it possible to develop device independent software. We introduce in this paper a robot visualization system implemented in Java. This graphical user interface is part of our robot simulation and monitoring system (RoboSiM). Currently two versions of the visualization exist, a Java 1.1 based system and its successor realized in Java 3D. Both applets display...

The Java programming language has gained substantial popularity in the past two years. Java’s networking features, along with the growing number of Web browsers that execute Java applets, facilitate Internet programming. Despite the popularity of Java, however, there are many concerns about its efficiency. In particular, networking and computation performance are key concerns when considering t...

John Lewis position Java will have a positive influence on software engineering practices at several levels. However, Java can also lead to software that lacks certain desirable qualities. The burden is still on educators and practitioners to uphold the best ideals. At least Java provides several language-based elements that directly support these high-quality ideals. Some good Java characteris...

Modern programming languages and operating systems encourage the use of threads to exploit concurrency and simplify program structure. An integral and important part of the Java language is its multithreading capability. Despite the portability of Java threads across almost all platforms, the performance of Java threads varies according to the multithreading support of the underlying operating ...

In recent years we have seen an explosion of markets for portable electronic devices such as PDAs, personal communicators and mobile phones. The size and complexity of applications, but also development constraints like getting the product to market on time make the use of high-level languages like Java necessary. Java 2 Micro Edition (J2ME) has emerged as a good solution for developing applica...
