Busking, S. (author)As datasets grow in size and complexity, the importance of comparison as a tool for analysis is growing. We define comparison as the act of analyzing variation or variability based on two or more specific instances of the data. This thesis explores a number of cases spread across the range of comparisons, from variability within one entity...doctoral thesis 2014

Gün, O.Y. (author)Realistic renderings contain a large amount of information about the spatial, geometric and material properties of prospective buildings that can directly affect design decisions, yet these images are most of the time used as after-the-fact representational visualizations. In this paper we propose a model to make the realistic images a very part...conference paper 2013

Shannon, P.T. (author), Grimes, M. (author), Kutlu, B. (author), Bot, J.J. (author), Galas, D.J. (author)Background: Biomolecular pathways and networks are dynamic and complex, and the perturbations to them which cause disease are often multiple, heterogeneous and contingent. Pathway and network visualizations, rendered on a computer or published on paper, however, tend to be static, lacking in detail, and ill-equipped to explore the variety and...journal article 2013

Hermans, F.F.J. (author)Spreadsheets are used extensively in industry: they are the number one tool for financial analysis and are also prevalent in other domains, such as logistics and planning. Their flexibility and immediate feedback make them easy to use for non-programmers. But as easy as spreadsheets are to build, so difficult can they be to analyze and adapt....doctoral thesis 2013

Wang, Chen (author), Pouliot, Jacynthe (author), Hubert, Frédéric (author)This paper proposes to investigate which among visual variables are more appropriate (if they are) for geo-visualization of 3D legal units in a probable 3D cadastre system. Visual variables, as proposed by Bertin (1983), include position, size, shape, value, color, orientation and texture. The appropriateness is evaluated base on whether a...conference paper 2012

Meijers, B.M. (author)The use of geo-information is changing by the advent of new mobile devices, such as tablet-pc's that harness a lot of computing power. This type of information is more and more applied in mainstream digital consumer products, in a net-centric environment (i.e. dissemination takes place via the Internet) and the advances in mobile hardware also...doctoral thesis 2011

Meijers, B.M. (author), Van Oosterom, P.J.M. (author)This paper introduces the concept of a space-scale partition, which we term the space-scale cube – analogous with the space-time cube (first introduced by Hägerstrand, 1970). We take the view of ‘map generalization is extrusion of 2D data into the third dimension’ (as introduced by Vermeij et al., 2003). An axiomatic approach formalizes the...conference paper 2011

Fisher-Gewirtzman, D. (author)Reviving neglected existing urban fabrics is one of the main frame-work for our future. A contemporary theory of conservation regarding architectural intervention and buildings subsequent re-use, has been developed to address a growing number of tired and neglected buildings. Rehabilitation is required for buildings that are no longer fit to...conference paper 2011

Hermans, F. (author), Pinzger, M. (author), Van Deursen, A. (author)Thanks to their flexibility and intuitive programming model, spreadsheets are widely used in industry, often for businesscritical applications. Similar to software developers, professional spreadsheet users demand support for maintaining and transferring their spreadsheets. In this paper, we first study the problems and information needs of...report 2010

(author)In this paper, we address the registration of two images as an optimization problem within indicated bounds. Our contribution is to identify such situations where the optimum value represents the real transformation parameters between the two images. Consider for example Mean Square Error (MSE) as the energy function: Ideally, a minimum in MSE...conference paper 2008
