Scientific visualization is a technology to extend our understanding of important processes. The technology has been used to visualize data structures, sub-atomic processes, chemical bonds, and other entities that are difficult to imagine without graphical enhancements. The genesis of the concept was the remarkable abilities of some humans to visualize esoteric processes; for example, much of Einstein’s theoretical development was the result of his ability to image vivid thought experiments. Linus Pauling used three-dimensional constructions to help him understand different chemical bonds whereas Watson and Crick’s ability to visualize and draw the double helix was the start of the DNA revolution. The purpose of visualization technology is to capture this imaging capability in a software environment allowing humans to gain both insight and predict the course of the process under investigation.

Many modern systems are controlled by Computer-Based Systems (CBS). Examples include commercial management information systems such as airline reservations, payroll information, stock central, and electronic banking systems, real-time embedded computer systems such as process control and computer integrated manufacturing systems, space systems, telephone and communications systems, transportation systems (automotive control, train control, ship control, traffic control), medical instruments, avionics systems, missile control systems, microcomputer controlled domestic appliances and point of sale systems. The CBS controlling these systems, typically consist of many networked geographically distributed subsystems. Each subsystem may be or may contain a multi-computer system. They are intensively dependent on software, and frequently depend on data communication networks, human-computer interaction, and special hardware. Engineers developing such systems have to work with CBS engineers responsible for the development of the supporting CBS. To be able to work with them they have to have a basic knowledge in the Engineering of CBS (ECBS). The paper describes the ECBS tasks to be undertaken by systems engineers during the development of systems they build, the CBS subjects they should understand and comprehend and the structure of the courses they should take to augment their knowledge. The proposed courses can be given as part of regular engineering undergraduate or graduate programs, or as training courses in industry. The proposed ECBS courses are being developed by the Education and Training Working Group of the IEEE Computer Society ECBS Technical Committee. The current version of the suggested courses is based on the results of the discussions of the working group during the ECBS98 conference in Jerusalem, and on work done during the past year by the group following ECBS98.

A new technique for automatic generation of VHDL testbenches is presented. Testbenches are generated using stimuli description in the WEGA language (K. Sapiecha and S. Deniziak, 1996) and VHDL entity declaration of the model under test. This technique makes it possible to reduce the length and complexity of testbenches by the factor of 10, on average. Moreover, describing testbenches in WEGA is much easier and flexible than describing them directly in VHDL. The source WEGA code is also more readable.

This paper investigates the underlying flaws in the development of the LAS despatch system and compares it with similar attempts from across the globe. The common themes that seem to plague ambulance despatch systems are investigated and put into context and a set of recommendations and lessons is proposed. The question of professionalism and ethics stands out and leads to the recognition of the value of failure analysis in the context of information systems development. Failure it is argued provides a great learning opportunity that may lead, when recognised, to enhanced professionalism and future success.

Model interpreters play an essential role in model integrated systems: they transform domain-specific models into executable models. The state-of-the-art of model interpreter writing needs to be advanced to enhance the reusability and maintainability of this software. This paper presents an approach which makes this possible through the use of structured specifications. These specifications let the programmer express traversal strategies and visitation actions in very high-level terms. From these specifications efficient traversal code can be automatically generated.

Distributed systems are essential for many real world applications. The paper presents an experimental programming model that enables visual configuration, deployment and control of data flow based collaborative systems, a class of distributed applications (DA). The programming model solves the problem of interoperability among DA functional components through the introduction of a fast middleware network software layer and by implementing a transparent message based communication between processes executing on machines connected by a local area network. At the next higher level, the programming model allows deployment and interconnection of encapsulated modules by logical composition of the entire collaborative application. The project differs widely from the existing systems in the network communication overhead, and the user interface design.

Information is essential to the performance, control, and coordination of an organization's functions. Yet, although an increasingly broad variety of models is used for the analysis and evaluation of organizational processes and functions, their information-processing aspects are only rarely considered in these models. In this paper I present an approach to the abstraction and description of information-processing aspects of organizational functions. The descriptions so obtained can then be translated into simulation models that, interfaced with suitable models of the organizational functions they support; can be used for the design and analysis of organizational functions as well as for the development of their supporting information systems.

This paper presents a methodology for selection of optimal software design parameters using the experimental design. When an organization is at the point of taking up a new project with an objective of improving the software quality, Taguchi method is applied for the software design process with an objective that not more than one error is found per software module. The strategy in robust design is to conduct off-line experiments using orthogonal arrays (OA) and to optimize the design by maximizing performance measures with respect to design parameters. Towards this a cause and effect diagram for design errors was drawn with opinions from customer, production, quality personnel and engineers. This diagram gave three most likely parameters as candidate for software design error, they are coupling, number of requirements per module and McCabe's cyclomatic complexity. It was planned to consider coupling parameter at two levels as low coupling at level 1 and high coupling at level 2, in case of number of requirements per module parameter three levels were considered they are one requirement per module at level 1, two requirements per module at level 2 and greater than two requirements per module as the level 3. In case of McCabe's complexity value<5 is set at level 1, value 5 to 10 is set at level 2 and value >10 is set at level 3. The possible number of factorial experiment required be conducted for levels selected for the three parameters is 18. The appropriate orthogonal array based on the guidelines of Taguchi is L/sub 9/ that is nine experiments need to be conducted to find the optimal software design parameters.

Model integrated computing (MIC) is gaining increased attention as an effective and efficient method for developing, maintaining, and evolving large-scale, domain-specific software applications for computer-based systems. MIC is a model-based approach to software development, allowing the synthesis of application programs from models created using customized, domain-specific model integrated program synthesis (MIPS) environments. Until now, these MIPS environments have been handcrafted. Analysis has shown that it is possible to "model the modeling environment" by creating a metamodel that specifies both the syntactic and semantic behavior of the desired domain-specific MIPS environment (DSME). Such a metamodel could then be used to synthesize the DSME itself allowing the entire design environment to safely and efficiently evolve in the face of changing domain requirements. This paper discusses the use of the Unified Modeling Language and the Object Constraint Language to specify, such metamodels, and describes a method for incorporating these metamodels into the MultiGraph Architecture, a MIPS creation toolset.
