Many chemical processes need large computation time to simulate. It has been observed that the speed of a process simulation depends to a large extent on evaluation of certain important functions in the system to be simulated. One such function is K-value estimation function which involves heavy vapor-liquid equilibrium calculations. Because of large number of K-value calculations, there can be a bottleneck in simulation convergence. Thus within process simulation applications computational speed is often emphasized and accuracy is compromised. In situ adaptive tabulation or ISAT, a storage and retrieval technique is proposed for speeding up K-value estimation in a process simulator (CHEMCAD®) using the input-output data. C language code is developed to implement ISAT algorithm for this application. The C code is then converted into Dynamic link library to be able to be used vii by main CHEMCAD® code as required. The overall testing with different K-value databases gave promising results improving computational time while maintaining accuracy. / text

Le mobile crowdsensing consiste à acquérir des données géolocalisées et datées d'une foule de capteurs mobiles (issus de ou connectés à des smartphones). Dans cette thèse, nous nous intéressons au traitement des données issues du mobile crowdsensing environnemental. En particulier, nous proposons de revisiter le problème d'étalonnage aveugle de capteurs comme un problème informé de factorisation matricielle à données manquantes, où les facteurs contiennent respectivement le modèle d'étalonnage fonction du phénomène physique observé (nous proposons des approches pour des modèles affines et non linéaires) et les paramètres d'étalonnage de chaque capteur. Par ailleurs, dans l'application de surveillance de la qualité de l'air que nous considérons, nous supposons avoir à notre disposition des mesures très précises mais distribuées de manière très parcimonieuse dans le temps et l'espace, que nous couplons aux multiples mesures issues de capteurs mobiles. Nos approches sont dites informées car (i) les facteurs matriciels sont structurés par la nature du problème, (ii) le phénomène observé peut être décomposé sous forme parcimonieuse dans un dictionnaire connu ou approché par un modèle physique/géostatistique, et (iii) nous connaissons la fonction d'étalonnage moyenne des capteurs à étalonner. Les approches proposées sont plus performantes que des méthodes basées sur la complétion de la matrice de données observées ou les techniques multi-sauts de la littérature, basées sur des régressions robustes. Enfin, le formalisme informé de factorisation matricielle nous permet aussi de reconstruire une carte fine du phénomène physique observé. / Mobile crowdsensing aims to acquire geolocated and timestamped data from a crowd of sensors (from or connected to smartphones). In this thesis, we focus on processing data from environmental mobile crowdsensing. In particular, we propose to revisit blind sensor calibration as an informed matrix factorization problem with missing entries, where factor matrices respectively contain the calibration model which is a function of the observed physical phenomenon (we focus on approaches for affine or nonlinear sensor responses) and the calibration parameters of each sensor. Moreover, in the considered air quality monitoring application, we assume to pocee- some precise measurements- which are sparsely distributed in space and time - that we melt with the multiple measurements from the mobile sensors. Our approaches are "informed" because (i) factor matrices are structured by the problem nature, (ii) the physical phenomenon can be decomposed using sparse decomposition with a known dictionary or can be approximated by a physical or a geostatistical model, and (iii) we know the mean calibration function of the sensors to be calibrated. The proposed approaches demonstrate better performances than the one based on the completion of the observed data matrix or the multi-hop calibration method from the literature, based on robust regression. Finally, the informed matrix factorization formalism also provides an accurate reconstruction of the observed physical field.

The practical part deals with strategic analysis, financial analysis and value estimation of a company by profit method of discounted cash flow.

Dans des situations où la perception visuelle est fortement contrainte ou déficiente, il est nécessaire de rendre perceptible l'information dans une modalité non visuelle, tout en prenant en compte des capacités sensorielles et mnésiques humaines. Par exemple, un non-voyant, souhaitant prendre connaissance d'un itinéraire, devra le parcourir de façon non visuelle et le mémoriser. Cependant, outre l'aspect matériel, la mise en œuvre de solutions alternatives (non visuelles) demeure confrontée aux capacités cognitives de l'utilisateur (compréhension, mémorisation, intégration de plusieurs informations, etc.). L'objet de cette thèse est de contribuer à la conception de techniques d'interactions permettant d'optimiser la transmission non visuelle d'informations. A ces fins, j'ai exploré l'apport de la multimodalité comme moyen d'optimisation permettant d'outrepasser les limites de la mémorisation. Je me suis concentré sur l'étude des techniques d'interaction basées sur les modalités auditives et tactiles, en limitant au maximum l'utilisation de la parole, afin de concevoir des techniques pour des environnements différents (flexibilité), d'optimiser l'utilisation de canaux perceptifs (exploitation des propriétés du son dans des messages audio pour transmettre plus d'informations, par exemple), d'éviter de limiter mes techniques par la barrière de la langue ou de sa compréhension et enfin, pour explorer d'autres solutions que la synthèse vocale seule. Les travaux de ma thèse ont mené à la conception, à l'implémentation et à l'évaluation de techniques d'interaction multimodale non visuelle, en réponse à différents contextes, dont, en particulier, ceux de la transmission d'informations de type <valeur>, <position> (couple de coordonnées) et <itinéraire> (séquence de couples direction-distance). Pour parvenir à concevoir mes interactions, j'ai, tout d'abord, effectué une revue de la littérature, afin d'en extraire les principaux facteurs de conception de techniques d'interaction dédiées à la transmission non visuelle d'information. Puis, j'ai organisé ces facteurs sous la forme d'un cadre d'analyse, sur lequel je me suis appuyé pour concevoir chacune de mes techniques. Trois expériences distinctes ont permis d'évaluer l'influence de facteurs de conception sur l'efficacité des interactions et la satisfaction des utilisateurs vis-à-vis des techniques. Je peux, notamment, citer l'implication des utilisateurs (actif ou passif), la présence d'aides explicites", la transmission de plusieurs informations en parallèle et la modalité principale utilisée et, le type de codage dans lequel est encodée l'information. / In situations where the visual perception is strongly constraint or deficient, it is necessary to make perceptible the information with a "not visual form" while taking into account human sensory and mnesic capacities. For example, a blind person wishing to acquaint an itinerary must read it under a non visual form and memorize it. However, besides the material aspect, the implementation of alternatives (non-visual) still faces to the cognitive abilities of the user (comprehension, memorization, integration of various information, etc.). The purpose of this thesis is to contribute to the design of interaction techniques allowing to optimize the transmission not visual of the information. For these purposes, I explored the feature of multimodality as a means of optimization, allowing of exceeding the memorization limits. I focused on the study of interaction techniques based on auditory and tactile modalities and by minimizing the use of the speech, in order to develop techniques for different environments (flexibility), optimize the use of perceptual channels (operating the properties of sound in audio messages to transmit more information, for example), avoid limiting my techniques by the language barrier or understanding and finally, to explore alternatives to the synthesised voice alone. The works of my thesis led to the design, to the implementation and to the evaluation of interaction techniques "non-visual" and "multiform", in answer to different contexts, whom in particular those of the information transmission of type <value>, <position> (pair of coordinates) and <itinerary> (sequence of couples direction-distance). To achieve design my interactions, I have made a review of literature in order to extract the main factors of design of interaction techniques dedicated to the transmission not visual of the information. Then, I have organized these factors in an analytical framework on which I have relied to design each of my techniques. Three separate experiments were led to evaluate the influence of design factors on the effectiveness of interactions and satisfaction towards users of technology. I can give some of them, the involvement of users (active or passive), the presence of explicit help, the transmission of several information in parallel, the main modality used and the type of coding in which is encoded the information.

This master thesis is concerned with the estimation of the market value of equity of Plzeňský Prazdroj, a.s. as at 30 September 2016. The market approach has been selected as the primary valuation approach with the largest impact on the value estimation; specifically the guideline public company method and the comparable transactions method are employed. The income approach based on the DCF Entity method verifies the value conclusion derived from the market approach. The going concern premise is supported by thorough analyses concerning the relevant market; market position of the valued company in relation to its competitors; and its financial health. The thesis concludes a clearly defined and justifiable range of value.
