and implementation phases of the Online Home Delivery System. The paper commences with highlighting the momentous aspects of computer technology and its development effects on today’s society. The system also brings to light how computer technologies are mounting the luxuries of today’s life by introducing new

. The approach is based on bundled-goods auctions and allows to achieve a high degree of analysability, economic efficiency and usability. The resource allocation service is implemented in Java based on the exchange of XML messages. The utilized schemata are expressed using XML DTDs as a lowest common

-configure to form an application-level overlay network, which they use to discover new services, perform late binding, and maintain weak consistency of names using soft-state name exchanges and updates. We analyze the performance of the INS algorithms and protocols, present measurements of a Java-based

The Ponder language provides a common means of specifying security policies that map onto various access control implementation mechanisms for firewalls, operating systems, databases and Java. It supports obligation policies that are event triggered conditionaction rules for policy based management

the media flow on the basis of the RTCP feedback of the client. The paper also describes the Java-based implementation of the system which uses the Java Media Framework library.

We describe Jcon, a new, Java-based implementation of the Icon programming language. The implementation includes a compiler and runtime system. The runtime system is novel in its concise and efficient object-oriented implementation of a dynamically typed language, as well as its simple mechanism

Many of today's wireless devices apply the Wireless Application Protocol (WAP). To fully implement the security features that WAP defines, a Wireless Identity Module (WIM) is required within the client device. This paper describes a prototype WIM implementation running on a Java-based smart

Abstract: Mobile information system require client side caching of data for various reasons. Caching issues are discussed in many scientific publications that mostly lack an usable implementation. Nearly all mobile devices support Java’s mobile information device profile (MIDP). In this paper we

Our work involves the development of a prototype Geographical Information System (GIS) as an example of the use of process networks as a well-defined high-level semantic model for the composition of higher-order functions. Our Java-based implementation of this prototype is known as Jade.
