Determination of pore space shape and size in porous systems using NMR diffusometry. Beyond the short gradient pulse approximation

The influence of finite length gradient pulses on NMR diffusion experiments on liquids confined to diffuse between two parallel planes is investigated. It is experimentally verified that the pore size decreases when determined using finite gradient pulses if the results are analyzed within the short gradient pulse approximation. The results are analyzed using the matrix formulation. The observed m

Three conceptions of explaining how possibly - and one reductive account

Philosophers of science have often favoured reductive approaches to how-possibly explanation. This article identifies three varieties of how-possibly explanation and, in so doing, helps to show that this form of explanation is a rich and interesting phenomenon in its own right. The first variety approaches “How is it possible that X?” by showing that, despite appearances, X is not ruled out by wha

EGIS+ European level developments of flexible learning models within geographical information systems (GIS) for vocational training

This paper deals with experiences from a successful previous pilot project under the Leonardo da Vinci programme implemented during the time period 2002-2006. That project E-GIS www.e-gis.org, is the basis for eGIS+ in the Lifelong Learning Programme (LLP). Ten partners from six European countries; Bulgaria, Lithuania, The Netherlands, Norway, Sweden and Portugal participated in E-GIS. During the

The paradigmatic tourist

In the Western thought tradition, the tourist has not been a subject worthy of intellectual musings and philosophical deliberations. Indeed, the tourist has been portrayed in primarily derisive ways. Nietzsche's remark, "Tourists-they climb mountains like animals, stupid and perspiring, no one has told them that there are beautiful views on the way," epitomizes the dominant attitude. Why does the

Coupled LDPC Codes: Complexity Aspects of Threshold Saturation

We analyze the convergence behavior of iteratively decoded coupled LDPC codes from a complexity point of view. It can be observed that the thresholds of coupled regular LDPC codes approach capacity as the node degrees and the number L of coupled blocks tend to infinity. The absence of degree two variable nodes in these capacity achieving ensembles implies for any fixed L a doubly exponential decre
