This research investigated the state of art of computer aided detection systems for digital mammograms, and evaluated the related techniques in image pre-processing, feature extraction and classification of digital mammograms. Furthermore, this paper explored the further research directions for next generation CAD for mammograms. It was identified that computer-aided detection techniques for ma...

In this paper, we describe a repository for architectural 3D-CAD models which is currently set up at the German National Library of Science and Technology (TIB), Hannover as part of the larger German PROBADO digital library initiative: The proposed PROBADO-framework is integrating different types of multimedia content-repositories and adding features available in text-based digital libraries. A...

Heterogeneous systems combine both data and control processing functions. A programmable DSP core forms the central component. The design of such systems establishes a new application of compilers in electronic CAD: In order to meet given real-time constraints and optimize chip area consumption, the DSP core needs to be customized for each application. In turn, this requires compiler support fo...

Coordination of Mechanical, Electrical and Plumbing (MEP) systems among themselves and with the architectural, structural and other building systems is an important, challenging and time consuming task on the design phase of multistory buildings. Many researchers have already expressed a critical view on the most widely adopted coordination process, which makes use of transparent trade drawings...

In this paper a methodology of building documentation is presented which is focused on the development of a 3D GIS. The methodology is based on the description of buildings by means of hierarchically structured architectural elements. This form fulfills the requirements of spatial databases and thus enables the implementation in 3D information systems. INTRODUCTION A complete documentation of a...

We are developing CollabCAD, a novel software architecture and toolkit, that supports sharing of arbitrary user-de ned objects or applications over intranets and the internet. Developers can use CollabCAD to rapidly re-engineer existing CAD applications to be collaboration-capable or build new collaboration-capable CAD applications. CollabCAD provides the following functionalities: 1. Support f...

Architects typically tell stories about their design intentions and then translate the verbal descriptions into action-based commands in Computer Aided Design tools. In other words, during the creative process the designer works in a “concepts space” that is different than the “properties space” available in the software virtual world of CAD tools. In this paper we propose to study the vocabula...

This paper describes an innovative learning environment, which integrates the Internet, 3D-CAD, and simulation tools in a web based learning system to ensure a better understanding of light perception in architectural space. The learning system comprises of a virtual laboratory, in which architectural planning examples can be represented three-dimensionally and be changed interactively. A devel...

Due to the expected rise in defect rate of devices in a nanotechnology based digital system, tools and techniques to build reliable architectures is gaining importance. In this paper, we propose an automated environment for reliability analysis and insertion of adequate redundancy for reliability enhancement. The input to this prescribed design flow is the architectural description of a non-red...
