TOOL PRESENTATION: The paper introduces the HeKatE design environment called HaDEs. The HeKatE project aims at delivering new knowledge representation methods for rule-based systems. Principal ideas include an integrated hierarchical design process covering stages from conceptual, through logical to physical design. These stages are supported by speci c knowledge representation methods: ARD+, X...

This paper presents an approach that enables a design tool to learn through its use. This approach uses a situated agent that wraps around a design tool and constructs concepts from interactions between the agent, the design problem and the use of the tool. The concept underpinning this research is founded on the ideas of “situatedness”. Situatedness involves the context and the observer’s expe...

This paper outlines a possible locus for knowledge-based systems in computer-aided architectural design education. It commences with a review of computer-aided architectural design and knowledge-based systems. It then proposes their use at various stages in CAAD education. Introduction There are a number of paradigms to consider in computer-aided architectural design education. We could think o...

Today, IC technology offers the possibility of integrating so many functions onto a single chip that it is indeed possible to implement an “environment-to-environment” system on a single chip. The literature is rich with papers discussing the System-on-Chip (SoC) opportunities; however, there has not been a wide market acceptance for this concept. The basic misconception has been attempting to ...

The need for exible le sharing in distributed systems is increasing in applications such as calendar management, collaborative editing of documents, collabor-ative software developments etc. The le sharing policies required in these applications are often very diierent from the traditional read/write policies. Hence, a exible way of specifying and implementing sharing policies on individual les...

US schools spend $5 billion annually on technology. However, despite the educational software market's size and potential impact on students, its fragmented nature makes it difficult for software producers to develop viable education business strategies based on traditional monolithic applications. Component-based software design radically changes this picture by supporting the design and disse...

{ With the growing emphasis on reuse, software development process moves toward component-based software design. In this paper we present an overview of the architecture-based approach to reliability estimation of the software composed of components. First, the common requirements of the architecture-based models are identiied, and the classiication is proposed. Then, the key models in each cla...

Complex software-based system design poses significant tractability problems that can be addressed by using higher level abstractions of the design such as architecture level abstractions. The architecture-level design distinguishes coarse-grain components and interactions between them. This paper develops approximate modeling of the interactions between the components in terms of a set of feat...

Context: Medication alerting systems are promising technologies but suffer from a poor usability. Objective: In order to help manufacturers of medication-related alerting systems improve the usability of their systems, this paper aims to provide evidence-based usability design principles. Methodology: Two independent analyses of the literature have been performed to identify, on the one hand, u...

The large variety of architectural dimensions in automotive electronics design, for example, bus protocols, number of nodes, sensors and actuators interconnections and power distribution topologies, makes architecture design task a very complex but crucial design step especially for OEMs. This situation motivates the need for a design environment that accommodates the integration of a variety o...
