Development of a modular room-temperature hydride storage system for vehicular applications
2016
The subject of this paper concerns the development of a vehicular hydrogen tank system, using a commercial interstitial metal hydride as storage material. The design of the tank was intended to feed a fuel cell in a light prototype vehicle, and the chosen hydride material, Hydralloy C5 by GfE, was expected to be able to absorb and desorb hydrogen in a range of pressure suitable for this purpose. A systematic analysis of the material in laboratory scale allows an extrapolation of the thermodynamic and reaction kinetics data. The following development of the modular tank was done according to the requirements of the prototype vehicle propulsion system and led to promising intermediate results…
Quelles approches cognitives pour les discours spécialisés ?
2018
Doctoral; Cet atelier doctoral part initialement d’une conférence prononcée au département de français de l’Université Craiova (Roumanie) en 2013 et capitalise sur les projets développés depuis à la MSH de Dijon, ainsi que sur les premiers résultats de thèses en cours, en particulier dans le domaine de la linguistique sensorielle.L’objectif est tout d’abord de situer la recherche sur les discours spécialisés au sein des sciences du langage, mais pas seulement, en partant de la proposition de Condamines / Narcy-Combes (2015) pour qui la linguistique appliquée, dont relève traditionnellement les discours spécialisés, est forcément une science située. On en tire les conséquences méthodologique…
Communication Interface Generation For HW/SW Architecture In The STARSoC Environment
2006
Mapping the application functionality to software and hardware requires automated methods to specify, generate and optimize the hardware, software, and the interface architectures between them. In this paper, we present a methodology flow to hardware-software communication synthesis for system-on-a-chip (SoC) design through STARSoC (Synthesis Tool for Adaptive and Reconfigurable System-on-a-Chip) tool for rapid prototyping. Our concept consists of a set of hardware and software processes, described in C-code, communicates through the streams channels. This methodology consists in analyzing dependences of data between processes and synthesis a custom architecture to interface it. Firstly, we…

Tiešsaistes Klientu Segmentācija, Izmantojot Klasterizācijas Metodes
2021
Bakalaura darba mērķis ir izpētīt tiešsaistes klientu segmentāciju, lai tā palīdzētu pieņemt loģiskus lēmumus par efektīvu mārketinga un reklāmas resursu izmantošanu. Darbā tika izmantotas divas klasterizācijas metodes: K-Medoīdu (K-Medoids) klasterizācija, un K-Prototipu (K-Prototypes) klasterizācija. Metožu izvēle tiek pamatota ar pētītā uzdevuma raksturojumu. Darba gaitā tiek aprakstīti gan abu metožu teorētiskie aspekti, gan metodes tiek pielietotas praktiski (izmantojot programmu R) konkrēta uzdevuma risināšanai. Tika veikta iegūto rezultātu analīze un salīdzināšana. Bakalaura darbā tika arī paskaidrota klientu segmentācijas nozīme veiksmīgam uzņēmumam, kā arī tika aprakstīts interneta…
Multiprocessor SoC Implementation of Neural Network Training on FPGA
2008
Software implementations of artificial neural networks (ANNs) and their training on a sequential processor are inefficient because they do not take advantage of parallelism. ASIC and FPGA implementations employ specific hardware structures to exploit parallelism in order to improve processing speed; however, optimizing resource usage requires the use of fixed-point arithmetic, thereby losing precision, and the final system is restricted to a particular network topology. This paper presents a mixed approach based on a multiprocessor system-on-chip (SoC) on a FPGA. The use of software-driven embedded microprocessors with custom floating-point extensions for ANN related functions allows for gr…
Représentations de l'Autre dans l'interaction : stéréotypes, prototypes, sosies et barbares
2011
Cet article pose la question du recours par les individus aux stéréotypes, mais aussi à différentes modalités de représentation de l'Autre, dans une interaction interpersonnelle. Il insiste sur l'influence du contexte figuratif, pour tenter de comprendre les rapports d'intersubjectivité propres à chacune de ces modalités, mais aussi pour chercher à expliquer leur fonctionnement dynamique et les facteurs qui peuvent provoquer le passage d'une modalité à une autre au cours d'une rencontre. Cette réflexion permet de mettre en avant les conditions d'intersubjectivité particulières qui semblent caractériser la communication avec un Autre identifié comme " différent ", contrairement à la communic…
NOTES ON A STATUE FROM THE COLLECTIONS OF THE NATIONAL MUSEUM OF UNION FROM ALBA IULIA
2016
This study proposes to re-evaluate a marble statue from the old collections of the National Museum of Union Alba Iulia. It was discovered by A. Cserni during excavations carried out at the Palace of the Governors of Roman Dacia, in 1898. It has been repeatedly published by Á. Hekler and Al. Diaconescu. While the latter author established dating and iconographic prototype of the statue, we believe that further details as discovery place and context, depiction, iconographic attribution and role of this work of art can be offered. Presence of a follower at the feet of the divinity, more precisely the right foot of a character – child, conveys us the idea of depiction of Eros, god of love. Usua…
Ultimate Order Statistics-Based Prototype Reduction Schemes
2013
Published version of a chapter in the book: AI 2013: Advances in Artificial Intelligence. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-319-03680-9_42 The objective of Prototype Reduction Schemes (PRSs) and Border Identification (BI) algorithms is to reduce the number of training vectors, while simultaneously attempting to guarantee that the classifier built on the reduced design set performs as well, or nearly as well, as the classifier built on the original design set. In this paper, we shall push the limit on the field of PRSs to see if we can obtain a classification accuracy comparable to the optimal, by condensing the information in the data set into a single tr…
New prototypes for the isolation of the anodic chambers in microbial fuel cells
2016
This work has been focused on the assessment of new prototypes of MFC in which a more strict separation of the anode and cathode compartments is looked for, in order to attain strict anaerobic conditions in the anode chamber and hence, avoid lack of efficiency due to the prevalence of non-electrogenic competing microorganisms and to optimize composition of the anolyte and catholyte. A cylinder reactor with an inner chamber with graphite bars acting as anodes and the outer one with a stainless steel tube acting as cathode was used in three different configurations and results obtained during lifetests are compared in terms of electricity production, cathode oxygen consumption and anode COD d…
