Fisher (1987a,b) introduced a performance task for conceptual clustering: flexible prediction of arbitrary attribute values, not simply the prediction of a single 'class' attribute. This paper extends earlier analysis by considering the effects of noise and other environmental factors. The degradation in flexible prediction accuracy that results from noise is mitigated by 'preferred' prediction...

One of the requirements which is poorly supported by spatial data models is a consistent management of different representations of the same spatial phenomena from different viewpoints or at different resolutions. This need is well known by users and designers. Modelling of applications, where users share the same database for different contexts and cartographic applications are examples of env...

There are challenges faced in today‘s world in terms of crime analysis when it comes to graphical visualization of crime patterns. Geographical representation of crime scenes and crime types become very important in gathering intelligence about crimes. This provides a very dynamic and easy way of monitoring criminal activities and analyzing them as well as producing effective countermeasures an...

The latest results from the WMAP satellite [1] confirm the success of the ΛCDM model, where ∼ 75 % of the mass-energy density is in the form of dark energy, with matter, most of it in the form of cold dark matter (CDM) making up the remaining 25 % . Neutrinos with masses on the eV scale or below will be a hot component of the dark matter and will free-stream out of overdensities and thus wipe o...

N-body simulations find a universal structure for the halos which result from the nonlinear growth of Gaussian-random-noise density fluctuations in the CDM universe. This talk summarized our attempts to derive and explain this universal structure by analytical approximation and simplified models. As an example, we show here that a 1D spherical infall model involving a fluid approximation derive...

Conceptual analysis of health and disease is portrayed as consisting in the confrontation of a set of criteria—a “definition”—with a set of cases, called instances of either “health” or “disease.” Apart from logical counter-arguments, there is no other way to refute an opponent’s definition than by providing counter-cases. As resorting to intensional stipulation (stipulation of meaning) is not ...

Background: Studies have shown that combining tender loving care (TLC) with the treatment of patients recurrent miscarriages can improve pregnancy outcomes. The importance TLC has long been recognised in studies on psychiatric, gerontological, and end-of-life nursing Western countries. Recently, randomised controlled trials (RCTs) used to examine improvement outcomes addition miscarriages; howe...
