An efficient indexing of past solutions is crucial to case-based design (CBD) systems performing complex retrieval on large case-bases. This paper suggests a hybrid approach to the indexing and retrieval of design precedents. The suggested approach accounts for the issues of classification manifested in architectural discussions on type and CBD literature. The indexing scheme integrates descrip...

This study explores the dynamics of firm relocation in Johannesburg, South Africa, by analyzing the mass exodus of firms out of the city's Central Business District (CBD) over the past two decades. Using a historical approach, this study examines the interplay between urban form and firm behavior. We typically understand urban form to be a function of firm behavior-that is, firms choose their l...

This paper presents a component model for designing and implementing flexible software components in Java. Our model defines a mapping of how the fundamental concepts of component-based development (CBD) should be implemented using the object-oriented (OO) constructs, available in the Java programming language. The benefit of this mapping is to shorten the distance between a component-based sof...

There is a lack of durable thinking on digital longevity. For this we require cross-domain communication and acceptation of standardized concepts, procedures, document formats and IT-tools. Four kinds of standards are required for preservation of digital documents over an indefinite period of time: standards for the architecture, document format standards for preservation, metadata standards fo...

The prospect of reducing the time, cost and risk of system development has increased the interest in developing systems from COTS (Commercial-Off-The-Shelf) products. The development of complex COTS-based systems is known to be an intricate and risk prone process. There are three main reasons for this. Firstly, suppliers develop COTS products with the objective of satisfying the needs of the ma...

Biodiversity is a key to human well-being. However universally acknowledged, this reality is not appreciated as much as one might imagine or hope. Having achieved a high standing in the Convention on Biological Diversity (CBD) in 1992, biodiversity appears to have gradually fallen from that position in the 20 years since. This is evidenced by the fact that most discussions and actions in relati...

1. The Executive Secretary is circulating herewith, for the information of participants in the seventh meeting of the Subsidiary Body on Scientific, Technical and Technological Advice (SBSTTA), a background paper prepared by the International Plant Genetic Resources Institute (IPGRI) on on-farm management of crop genetic diversity. This information note supplements the progress report by the Ex...

The proposed patterns presented in this paper describe a sequence of steps for the Distributed Component Development integrating different known principles to support the process. The involved principles are: part of Catalysis method used as a Component-Based Development (CBD) method to define, specify and design the distributed components; the middleware to support components distribution and ...

Introduction The need to conserve farm animal biodiversity is accepted by many countries through the ratification of the Convention of Biological Diversity (CBD, 1992). Although farm animal breeds are not well defined in general terms, they are the typical unit for conservation. Based on an inventory of the actual breeds (on the global scale this is done by FAO through the world watch list, Sch...
