In this paper we present a mathematical model based on graph homomorphisms permitting the analysis and the behavioral envisioning of software based systems. We first try to explain why a qualitative approach is needed and which are the limitations and problems of quantitative analysis techniques. Follow some results of a qualitative abstraction tool and some simple application examples on telec...

This paper investigates whether the wider context in which a sentence is located can contribute to a distributional representation of sentence meaning. We compare a vector space for sentences in which the features are words occurring within the sentence, with two new vector spaces that only make use of surrounding context. Experiments on simple subject-verbobject similarity tasks show that all ...

A method of generating complementary eigenspaces optimised for inter-class and intra-class separability respectively is presented. The objective of creating these spaces is to improve the efficiency of eigenspace search algorithms. The inter-class optimised space may also be used to improve classification and a quantitative evaluation of this against conventional Principal Component Analysis an...

The research question is: “How to develop and apply acoustic artefacts and design methodologies for improving soundscapes in urban outdoor spaces?” In the project, this research question is limited to one specific type of urban outdoor space – city-park – and to two types of acoustic design artefacts. These are: I. Dynamic promotion of qualitative site specific sounds (e.g., the overall site sp...

Yeap and Jefferies [1] show how a description of each local space is computed and by realising how these local spaces are connected, a cognitive map of one’s environment will emerge. However, roboticists have shown that it is difficult to compute such a map with precise metric information. In this paper, we show some preliminary ideas as to how a qualitative map could be constructed out of loca...

Many generic results have been proved, especially concerning the qualitative behaviour of solutions of partial differential equations. Recently, a new notion of “almost always”, the prevalence, has been developped for vectorial spaces. This notion is interesting since, for example, prevalence sets are equivalent to the full Lebesgue measure sets in finite dimensional spaces. The purpose of this...

This chapter focuses on the World Wide Web (Web) as a provider of shared information landscapes. It reviews our work to design 3D spaces for information navigation and social interaction, and suggests an approach to such design based on an experiential theory of meaning. The increasing use of virtual 3D space in information environments is noted, and Personal Spaces are contrasted with Public P...

this paper is a part of study about the impact of the microclimate on the space use and the user’s behaviours. the purpose of our study is to get an in-depth understanding of how people use out door public spaces in different climatic conditions, how their behaviour and perception of the space change with the climatic variations. we have employed a multi-method approach which combines a “qualit...
