This paper describes a series of tests designed to evaluate the capacity of a personal computer (PC) based statistical curve-fitting program called MIX to quantify composite populations within multi-modal particle-size distributions. The main
Développement de l'hypothèse du décalage spatial. Méthodes pour tester cette hypothèse : analyse de l'impact de la ségrégation résidentielle sur le marché du travail, comparaison des temps de migration alternante, comparaison des salaires, mesure de
la proximité du travail, expériences spatiales, amélioration du transport, relocalisation forcée du logement, relocalisation des entreprises. Défis méthodologiques lors du test de l'hypothèse du décalage spatial.
Factors controlling carbonate dissolution rates quantified in a field test in the Austrian alps
data, and limestone pedestals. For the field test, 70 carbonate tablets were exposed to natural dissolution for 1 year, over 13 sites on the north slope of the Hochschwab Massif in the Austrian Alps. The influences of altitude, subsoil vs. sub-aerial
Testing bedload transport formulae using morphologic transport estimates and field data : lower Fraser River, British Columbia
tested in this paper include the original and rational versions of the Bagnold formula, the Meyer-Peter and Muller formula and a stream power correlation. The formulae differ in their sensitivity to input variables and between reaches. Average annual
Un projet test d'uniformisation des données GPS a été effectué à l'Ouest de l'Algérie sur 2 campagnes GPS déjà observées et traitées, dans les régions d'Oran, Arzew et Mostaganem. L'objectif de ce test consiste à adopter une méthodologie
A scanning t-test algorithm for detecting multiple time-scale abrupt changes in the level of a time-series was used to analyze an 8000 year time series of annual precipitation which was reconstructed from tree rings for the Nevada Climate Division 3
in the western USA. The results suggest that the precipitation reconstruction series is quite valuable for climate-change research on multi-centurial time scales in the western USA, and that the scanning t-test and coherency detection algorithms may have a wide
On the Faucon stream (South French Alps), representative of clay-shale basins, results of various rheological tests and numerical experiments are presented and discussed. The calibration of the model was undertaken using the results of both
The AA. present results of a test of the Hall et al. (1993, 1997) hypothesis that, in the early Pliocene, the alpine glaciers terminated at the edge of a Wright Valley fjord. The test consisted of re-mapping the surficial geology of the same 5
A model to simulate channel changes in ephemeral river channels and to test the effects of hydrological changes due to climate change and/or land use change was developed under the auspices of the EU funded MEDALUS programme (Mediterranean
periods of up to several decades. The modelling is based on cellular automata but with calculations for water and sediment continuity. the initial tests of the model are demonstrated and some validation results are presented.
Effets de la densité et de l'angle de pénétration. Test de charge cyclique-relaxation. Expériences dans un tunnel à vent. Comparaison des croûtes biotiques et de sel.
Forme urbaine, qualité de vie, environnements naturels et construits. Eléments de réflexion et test de mesure pour la région métropolitaine de Montréal
des dimensions socio-économiques, urbanistiques et environnementales caractérisant les espaces urbains : choix de variables clés pour un test. Un modèle synthétique d'analyse est conçu à partir d'un nombre restreint d'indicateurs. Les résultats, issus
The survey conducted has revealed that INTERREG projects have played an instrumental role for spatial development of northern Poland in several aspects. They have resulted in the elaboration and testing of new instruments important for spatial
Test d'une série d'hypothèses sur les conditions dans lesquelles les organisations adoptent ISO 9000, la série de normes internationales pour la gestion de la qualité, en utilisant les données d'un panel de 130 pays entre 1995 et 2001.
Méthodologie et méthodes d'évaluation biologique de la qualité des eaux : test biologique, bio-indication, diagnostic écotoxicologique. Méthodes d'études physiopathologiques des poissons : suivi clinique et anatomopathologique de l'organisme
This research tests the following hypotheses : the Polynesian settlement of Tonga is reflected in the sediment record, particularly through the appearance of microscopic charcoal in wetlands; the coastal swamp of Avai'o'vuna can provide information
