A framework for interpolating scattered data using space-filling curves

The analysis of spatial data occurs in many disciplines and covers a wide variety activities. Available techniques for such analysis include spatial interpolation which is useful for tasks such as visualization and imputation. This paper proposes a novel approach to interpolation using space-filling curves. Two simple interpolation methods are described and their ability to interpolate is compared to several interpolation techniques including natural neighbour interpolation. The proposed approach requires a Monte-Carlo step that requires a large number of iterations. However experiments demonstrate that the number of iterations will not change appreciably with larger datasets

Carrion Beetles Visiting Pig Carcasses during Early Spring in Urban, Forest and Agricultural Biotopes of Western Europe

Carrion beetles are important in terrestrial ecosystems, consuming dead mammals and promoting the recycling of organic matter into ecosystems. Most forensic studies are focused on succession of Diptera while neglecting Coleoptera. So far, little information is available on carrion beetles postmortem colonization and decomposition process in temperate biogeoclimatic countries. These beetles are however part of the entomofaunal colonization of a dead body. Forensic entomologists need databases concerning the distribution, ecology and phenology of necrophagous insects, including silphids. Forensic entomology uses pig carcasses to surrogate human decomposition and to investigate entomofaunal succession. However, few studies have been conducted in Europe on large carcasses. The work reported here monitored the presence of the carrion beetles (Coleoptera: Silphidae) on decaying pig carcasses in three selected biotopes (forest, crop field, urban site) at the beginning of spring. Seven species of Silphidae were recorded: Nicrophorus humator (Gleditsch), Nicrophorus vespillo (L.), Nicrophorus vespilloides (Herbst), Necrodes littoralis L., Oiceoptoma thoracica L., Thanatophilus sinuatus (Fabricius), Thanatophilus rugosus (L.). All of these species were caught in the forest biotope, and all but O. thoracica were caught in the agricultural biotope. No silphids were caught in the urban site

Etude theorique du transPort électronique et du contrôle de charge dans AlO,48_\mathsf{O,48}In0,52_\mathsf{0,52}As/Ga0,47_\mathsf{0,47}In0,53_\mathsf{0,53}As/InP. Applications a la realisation de HEMT

The purpose of this work is to study the AlInAs/GaInAs system and its applications to HEMT devices. First a Monte-Carlo method has been used to compute the transport parameters of InGaAs and InAlAs lattice matched to InP, and values of diffusion coefficients for these materials are reported for the first time. Then the charge control in InAlAs/InGaAs/InAlAs double heterostructure has been investigated by mean of ID model, and the influence of technological parameters is discussed. Finally a realistic device has been studied using a twodimensional MonteCarlo simulation. The main physical phenomena involved in the device's behaviour are described, and electrical characteristics are presented.Ce travail a pour but d'étudier les potentialités de l'hétérojonction AlInAs/GaInAs pour la réalisation de transistors à haute mobilité d'électrons (HEMT). Dans un premier temps, les phénomènes fondamentaux gouvernant le comportement du composant: transport électronique et contrôle de charge, sont étudiés avant d'envisager la simulation du composant complet. La méthode de Monte-Carlo est employée afin de préciser quantitativement les propriétés de transport des matériaux AI$_{O,48}$In$_{O,52}$As et Ga$_{O,47}$In$_{O,53}$As, et de donner une premiere déternùnation de leurs coefficients de diffusion. La modélisation unidimensionnelle de la double hétérojonction AlInAs/GaInAs/AlInAs nous a permis de dégager l'influence de quelques paramètres technologiques sur le contrôle de charge. Nous avons ensuite étudié comment ces propriétés, a priori intéressantes, se traduisent sur le fonctionnement d'un HEMT. Pour cela, la simulation Monte-Carlo bidimensionnelle d'une structure proche des réalisations expérimentales, nous a permis de mettre en évidence les principaux phénomènes physiques qui interviennent dans le fonctionnement du HEMT et d'en donner les caractéristiques électriques
