La canne à sucre est cultivée pour la production de sucre et d’électricité exportée sur le réseau. Actuellement, les taux de fibre de la canne dans les chargements livrés à l’usine augmente. L’objectif est de définir les conséquences de la réception de chargements contenant plus de fibres (lié aux variétés et au non canne) sur l’analyse de la canne et la performance du complexe sucrerie centrale thermique (production de sucre, de mélasse et d’électricité).La comparaison des méthodes d’analyses de la canne a permis de sélectionner la méthode Berding et Pollock comme méthode de référence pour l’analyse du sucre, de la matière sèche soluble et de la fibre.Une méthodologie d’analyse de la canne au laboratoire utilisant un broyeur et une presse est proposée Des relations sont établies pour calculer, en fonction des analyses effectuées sur le jus de presse et la bagasse, le débit horaire de canne, l’énergie nécessaire au broyage de la canne, le taux d’extraction du sucre dans le jus et le pouvoir calorifique de la bagasse. Ces mesures sont ensuite utilisées dans des bilans massique et énergétique de la sucrerie et de la centrale thermique. Ce bilan aboutit à la production de sucre cristallisable, de mélasse et d’électricité sur le réseau.Les résultats indiquent que par rapport à la R579, la variété fibreuse R585 produit 8% de sucre en moins et 51% d’électricité en plus alors que la R570 produit 3,9% de sucre en plus et 27% d’électricité supplémentaire. Par rapport à de la canne propre, une coupe de la canne entière entraine une diminution de la production de sucre de 16% et une augmentation de la production d’électricité de 21%. La coupe de canne avec feuilles entraine une baisse de 4% de la production de sucre et une augmentation de 12% de la production d’électricité. / Sugarcane is cultivated to produce sugar en electricity to the grind. Recently, the fibre content of cane delivered to the mill increase. Objective of this works is to determine the influence of cane delivered to the mill with more fibre (due to variety and trash) on cane analysis, sugar mills and energy plant complex performance (sugar, molasses and electricity production).Cane analysis method comparison show that Berding and Pollock method was the most appropriate for sugar, soluble dry matter and fibre in cane measurement.A laboratory cane analysis methodology using a grinder and a press is proposed. Relations are established to calculate according to juice and bagasse analysis, the cane capacity, energy for shredding cane, sugar extraction in juice and bagasse calorific value. Those analysis are used in mass and energy balance through the sugar and cogeneration plant. That balance conduct to crystallisable sugar, molasses and electricity exported.Results shows that compared to R579, the fibre variety R585 produce -8% of sugar and +51% of electricity, the R570 variety produce +3.9% of sugar and +27% of electricity. Compared to clean cane, whole crops harvesting decreased sugar (-16%) and electrical (-21%) production. Cane harvest with leaves conduct to a decrease of sugar (-4%) and increase of electrical (+12%) production.

Depuis les années 1980-90, les études de l’art préhistorique ont développé les analyses techniques afin de rechercher les choix individuels, aborder le contexte techno-économique des groupes paléolithiques, et proposer un modèle social et culturel. Les recherches menées sur l’art mobilier ont apporté des résultats tels que l’identification des outils, ou plus généralement les processus mis en œuvre pour la réalisation des œuvres. L’ensemble de ces renseignements a permis de comprendre la succession des gestes des graveurs et ainsi apercevoir l’Homme derrière la technique.Dans la suite de ces travaux, une étude des processus techniques des supports de l’art mobilier en matières osseuses depuis leur acquisition sur l’animal jusqu’à la réalisation de la gravure, semblait nécessaire pour compléter les informations du système technique, et documenter la complémentarité support/décor. L’objectif est de retracer dans un premier temps les différentes actions sur la matière première conduisant à l’obtention d’un objet orné. Puis, dans un second temps d’analyser la place du décor dans la chaîne opératoire de l’objet, afin d’identifier des possibles variations dans les choix techniques de cette production. La méthodologie choisie fait référence, à la fois aux travaux développés depuis les années 1970 en industrie osseuse, et à ceux en art mobilier. Une approche expérimentale a permis la création et l’observation d’un corpus de stigmates, amenant à l’étude d’un ensemble choisi d’objets archéologiques. L’analyse détaillée à la fois des éléments de transformation du support et de la description du décor, a permis de proposer la chaîne opératoire de chacun d’entre eux, de la phase d’acquisition de la matière à celle de son utilisation. Le corpus archéologique a été constitué de pièces des gisements magdaléniens de la vallée de l’Aveyron, Lafaye, Plantade, Montastruc et Courbet, conservées au Muséum d’Histoire Naturelle de Montauban et au British Museum. / Since the 80s and 90s, the studies of prehistoric art are mostly directed towards technical analyses allowing us to look for individual choices, to approach the techno-economic context of the palaeolithic groups, and to propose social and cultural models. Researches carried out on osseous mobiliary art have led to identify the tools and, more generally, the processes used for the manufacture of these objects. This set of information brought about a better comprehension of the engravers’ hand gestures, allowing to perceive the Man behind the technique.Following these works, a study of the technical processing of portable art on osseous materials from the acquisition of the raw material to the realization of engravings appeared necessary to complete our knowledge of the technical system, and get information about the complementary relationship between blank and decoration. The first objective was to understand the various actions performed on the raw material to obtain the final decorated piece. The second aim was to analyze when the decoration takes place during the “chaîne opératoire” and to identify possible variations in the technical choices during the whole process. The chosen methodology makes reference at the same time to the research developed since the 1970s in osseous industry, and to studies specifically dedicated to mobiliary art. An experimental approach was used to observe a large variety of traces and to create a reference corpus, that was useful afterwards to select a set of archaeological objects to be studied. The simultaneous analysis of the transformation of the raw material and the description of the decoration led us to propose a full “chaîne opératoire” for each of them, from the acquisition of the raw material to the use of the final artefact. The archaeological corpus was constituted by pieces from the Magdalenian sites of Lafaye, Plantade, Montastruc and Courbet in the Aveyron valley, cared in the Natural History Museum of Montauban (Tarn-et-Garonne, France) and in the British Museum (London, England).

La technologie est un facteur important pour obtenir des avantages concurrentiels, par conséquent, les processus d'acquisition, de développement et d'application rapide de la technologie sont essentiels pour les entreprises. Les entreprises comptent sur leurs activités internes de R & D pour maintenir leur compétitivité technologique, mais elles élaborent aussi des stratégies de coopération. Elles ont encore la possibilité de mettre en œuvre des acquisitions ou des alliances si elles veulent croître. En conséquence, une préoccupation majeure pour les chercheurs et les praticiens est «comment font les entreprises pour obtenir la technologie?» Et «quelles sont les sources de technologies que les entreprises souhaitent mobiliser ? Cette recherche examine les facteurs qui influencent le choix de modes d’accès à la technologie (TSM) dans des entreprises technologiques à forte intensité en Iran et de haute technologie tout en décrivant la façon dont ces facteurs influents sur le choix de la TSMs. 167 entreprises iraniennes actives dans quatre secteurs ont été interviewées : la microélectronique et télécommunications (y compris électronique), technologies de l'information, la biotechnologie, et la nanotechnologie. Dans ces entreprises, les tendances à opter pour des développements technologiques internes ou externes à étudier selon différents facteurs dont : la réussite des expériences passées, l’accroissement des ressources technologiques propres, la phase concernée du cycle de vie de la technologie, le degré d'incertitude technique, la qualité des ressources humaines internes et la capacité d’absorption. / Technology is a top management major concern in order to increase the competitiveness of companies. Thus processes relating to technology acquisition, development and application become strategic key factors. Companies rely on their own R&D activities but also on partnership. Thus, literature points out that the use of technology sourcing modes by itself could create advantages for the firms. Among others technology sourcing modes are: - alliance through technology collaboration, consortium, research joint venture,- acquisition through licensing, R&D sub contracting, technology purchasing. As a consequence academics and practitioners direct their attention toward two main questions: when is it necessary to develop a new technology and what is the best sourcing mode? Thus, this research studies the decision key factors of Iranian high technology companies in the field of technology sourcing. Internal and external variables are investigated including: internal scientific resources, past experience success, absorptive capacity, and, the concerned phase of the technology live cycle, the technological uncertainty.

Basic issues of introducing E - Justice into civil proceedings The subject of this thesis is modernization of civil proceedings, pushed forth by the department of justice, via implementation of information and communication technologies. Specific focus is granted to the perpetually forming phenomenon known as E - Justice, which is meant to enrich the judiciary by not only allowing complete rationalization of procedures to take place, but also by making civil proceedings more open and accessible to its clients. Modern technology and the electronic form of data, which it provides, have the potential, under the assumption that it will thoroughly be established in the judiciary sector, to bring vigor and financially effective processes while at the same time augmenting the processing capacity. The aim of this thesis is to emphasize the critical moments arising from the implementation of E - Justice, to concisely characterize the present state of this phenomenon in Czech republic and to propose its further attainable developmental pathways with respect to advancements of the information society. All of this will be covered while placing an emphasis on regulation of the civil proceedings. Because of the space limitations imposed by this assessment the entire battery of aspects regarding E - Justice and...
