From a software engineer's point of view, refining object-oriented specifications in distributed software architectures seems to be a promising way for developing programmes. Unfortunately, the use of the most of current coordination models prevents a dire ...
This paper presents a pragmatic way to build a Reliable CORBA Event Service. Our approach is pragmatic in the sense that, rather than building the service from scratch, we show how to obtain it, through a simple transformation, from any standard (unreliabl ...
The article presents the first results of the CrySTINA project. We analyze and structure the security problem domain in the TINA-C architecture and present our approach to provide the necessary security functionality in the form of self-contained applicati ...
Distributed systems have strong similarities with object systems. However, coordination models for these systems have slightly different requirements. This paper presents a specific coordination model for distributed object systems, built on hierarchical e ...
This paper argues that the Reference-Model for Open Distributed Processing (RM-ODP) is a suitable basis for developing new standards pertaining to domain architectures, common business facilities, and common objects. However, the RM-ODP is difficult to und ...
We describe a speechreading system that uses both, shape information from the lip contours and intensity information from the mouth area. Shape information is obtained by tracking and parameterising the inner and outer lip boundary in an image sequence. In ...
This dissertation studies the problems to solve in order to use the invocation paradigm to express replicated object communication in fault-tolerant distributed systems. The ultimate goal is to define abstractions which achieve replication encapsulation, i ...
