Prédiction de cycle et stratégie de gestion énergétique basée sur une méthode d’optimisation globale
2017
International audience; La nécessité de prédire le cycle de conduite d’un automobiliste afin d’améliorer sa gestion énergétique et ainsi réduire la consommation de carburant a été démontré (Debert, Quigley). Dès lors, il serait aisé d’appliquer une méthode d’optimisation globale, telle que la Programmation Dynamique (DP en anglais), pour obtenir la stratégie optimale. Cette méthode est déjà utilisée dans de nombreuses applications (Sciarretta), mais au quotidien nombreux sont les facteurs environnants qui peuvent perturber les conditions de circulation (météo, travaux, accidents....) et impacter le cycle de conduite. Il est donc nécessaire d’élaborer une stratégie adaptative en temps réel. …
Augmented context based on prediction for efficient knowledge reuse of business knowledge in design
2017
Works on the design context augmentation in product design, makes it possible to make awareness designers on their choice in the design for assembly. The presented approach will conclude on the method to develop a informatic system, based on case studies of mechanical design. The purpose of the project is to capture the design intent, in order to provide useful assistance to stakeholders, such as design support, decision making, verification/validation, and data structuring.
A multi-agent based cooperative control model applied to the management of vehicles-trains
2017
The use of individual vehicles is becoming more and more important in inner cities, leading to many side problems such as traffic jam, air pollution and accidents. Intelligent vehicles have been studied so as to overcome these problems. Some solutions provided by these works are already available to the general public market such as city safety systems, lane assists,... Many research works are focusing on finding suitable and acceptable solutions to these problems and dealing with traffic jam management. The proposal can tackle the traffic jam problem whether on system level or on individual vehicle providing better control and perception systems aimed at reducing time response and/or at in…
Study of control command of dynamic platform for driving simulation and influence on simulator sickness
2013
Simulation has been intensively involved nowadays in research and development for automotive industry. Driving simulators are one of those simulation techniques which are used to evaluate the prototypes for the vehicle dynamics and driving assistance systems. However with the driving simulator, there is a lock associated with its use. Because representing a permanent scenario as scale 1 is quite difficult. Because of that difficulty, motion/simulator sickness is an inevitably important topic to study.This thesis proposes to explore methods and tools to implement in static or dynamic simulators. In this implementation, studies of simulator sickness are conducted with objective measures (via …
Conception basée sur les origamis pour l'impression 4D de structures déployables
2020
Deployable structures can be deformed between the different configurations through predetermined mechanisms, showing the great potential in many engineering applications. However, their exquisite and intricate mechanisms also bring a great difficulty to the design of its structure. With the growing 4D printing efforts, its self-transforming characteristics under external stimuli provide new possibilities for deploying complex and challenging driving structures. Furthermore, origami-based engineering has provided tremendous technical support for structural conversion, especially from 2D to 3D states, leading to many design studies based on origami-inspired deployable structures. However, the…
Si j'aurai su, j'aurai pas venu" : éclairage stratégique sur le lancement simultané des deux " Guerre des Boutons "
2014
“If I knew, I will not come”: strategic insight on the simultaneous launch of the two Guerre des BoutonsThe purpose of this paper is to propose an insight on an unusual strategic situation in the movie industry: thesimultaneous launch on screens of two almost identical movies, La Guerre des Boutons. After recalling the stakesattached to the product launch in the film industry, a monograph devoted to this direct confrontation, supplementedby an analysis of the critics of spectators, is proposed. This analysis reveals determinants (the conflictand lack of control in the film industry) and consequences (sub-optimal strategy) of the temporal agglomeration.
Virtuālās realitātes adaptera ar elektriski vadāmām šķidrā kristāla lēcām izmantošana akomodācijas funkcijām
2020
Maģistra darbs ir uzrakstīts latviešu valodā uz 45 lapaspusēm. Tas satur 26 attēlus, divas tabulas, četrus pielikumus un 38 atsauces uz literatūras avotiem. Darba mērķis ir izstrādāt akomodācijas funkciju treniņu iekārtu, kas tiek darbināta ar elektriski vadāmām šķidro kristālu lēcām. Metode: elektriski vadāmās šķidro kristālu lēcas tiek iestrādātas virtuālās realitātes adapterī un darbinātas ar speciāli izstrādātu kontrolieri, kas izstrādāts uz Arduino programmatūras bāzes. Subjekti: eksperimentā piedalījās divas dalībnieces 26 un 31 gadus jaunas. Secinājumi: izveidotā iekārta faktiski ir izmantojama akomodācijas funkciju uzlabošanas/trenēšanas nolūkiem, lai gan ir nepieciešami vairāki būt…
Acceptabilité des vins à teneur réduite en alcool. Importance relative du goût et de l'information
2014
L’évaluation de l’acceptabilité des vins est généralement effectuée dans des conditions de dégustation à l’aveugle, afin de ne pas influencer le jugement du dégustateur. Cependant, les vins sont rarement présentés à l’aveugle en situation réelle de consommation, et de nombreux paramètres extérieurs au vin tels que le packaging, le prix, l’information sur l’étiquette peuvent influencer la perception sensorielle et l’acceptabilité globale du produit.L’objectif de cette étude était d’évaluer l’importance relative des caractéristiques sensorielles et de l’information dans l’acceptabilité de vins à teneur réduite en alcool.Pour cela, une méthodologie a été mise en place en faisant varier le vin …
