Design patterns have greatly helped spreading a limited number of well-tried solutions to recurring object-oriented problems. But as new patterns are introduced at a steady rate, the concept must evolve so that tools can help programmers not to be lost, facing a host of patterns. In this paper, we propose that design patterns be systematically analyzed and reformulated to exhibit a reasoning bi...

Charcoal records from lake sediments may show changes in fire frequency over thousands of years, but such records are ambiguous with regard to the actual locations of fires. Using a comparison of fire dates from an 1800-year lake sediment record from the west coast of Vancouver Island (British Columbia, Canada) and dates of last fire from 38 sites in the same watershed using tree-ring and soil-...

résumé – Une approche combinatoire de la ressemblance phonétique entre langues En exploitant une représentation géométrique des phonèmes vocaliques, nous réalisons un modèle bidimensionnel dans lequel des voyelles sont des points et les distances entre ces points expriment des différences auditives. Ceci nous permettra de décrire le système vocalique d’une langue du point de vue d’une autre lan...

On a regional scale, some of the most profound impacts of climate change due to increases in greenhouse gases would probably be major changes in the hydrological cycle, in water availability, in agricultural production and in the use of energy. This paper gives a brief overview of studies carried out on climate change and possible impacts on hydrology and water resources in India, covering also...

The philosophical logic developed by the Franco-Romanian thinker Stéphane Lupasco (Bucharest, 1900 – Paris, 1988) includes a systems approach to epistemology that complements independent work of von Bertalanffy and other general systems theorists. Basing his theory primarily on quantum mechanics, Lupasco proposed that the fundamental dualistic antagonism present in energy and accordingly in all...

Semi-classical measures and eigenvalue crossings). — Semiclassical study of multidimensional crystals leads naturally to the following question: how do semiclassical measures propagate through energy level crossings ? In this contribution, we discuss a simple 2 × 2 system which displays such a crossing. For that purpose, we introduce two-scaled semi-classical measures, which describe how the us...

Stylometric authorship attribution is a fundamental problem. The basic idea behind the research is that one can determine the authorship of a document on the basis of cognitive and linguistic quirks that uniquely identify a person. In many cases, however, noise in the original documents can make this analysis more difficult and less reliable. We investigate the errors introduced by a typical op...
