Le nombre de véhicules électriques (VEs) augmente de plus en plus depuis des dernières années. De ce fait, des problèmes d’attente dans les stations de recharge apparaissent, vu leur nombre limité dû aux coûts élevés d’installation. En outre, il y a des problèmes liés d'une part à l’autonomie due à la capacité limitée des batteries et des problèmes liés d'autre part à la crainte d’avoir une portée insuffisante pour atteindre une destination du véhicule ou de tomber en rupture d’énergie entre un point de départ et un point de destination. Faire de la planification de recharge et diriger les conducteurs vers des stations de recharge disponibles pendant leur trajet pourraient contribuer à résoudre ces deux problèmes. Pour ce faire, une communication bidirectionnelle entre les VEs et la grille serait utile. C’est dans ce cadre, que ce projet est proposé. D’une part, dans ce projet, on propose une architecture sécurisée où les VEs et la grille intelligente peuvent échanger les données pour effectuer une réservation des créneaux horaires dans les stations de recharge et planifier les itinéraires. Une étape d’authentification et d’autorisation du véhicule ou de l’usager est primordiale pour garantir la sécurisation des échanges et la confidentialité des données des VEs. Cela implique une demande de fournir des informations en mode crypté à travers les protocoles de sécurisation. Cette étape d’authentification et d’autorisation est établie après une étape de notification du VE. D’autre part, on met en place un nouveau schéma pour planifier les itinéraires des VEs. Ce schéma prend en compte l’état de charge du véhicule, son origine, sa destination et les stations de recharge disponibles sur la route. Le schéma établit la réservation dans les stations selon des mécanismes d’optimisation de temps d’attente du VE dans les stations de recharge et de sa consommation d’énergie globale durant son voyage depuis le point d’origine jusqu’à la destination voulue. / Abstract : The number of electric vehicles (EVs) has increased significantly in recent years. Owing to the limited number of charging stations (CSs), the waiting time in charging stations has swelled. In addition, the limited capacity of EV batteries can evoke the drivers’ range-anxiety, defined as the fear of having insufficient range to reach a destination. Make a charging planning and directing the drivers to the available charging stations during their journey could help to solve these problems. To do this, a bidirectional communication between the EVs and the smart grid would be useful. It is within this framework that this project is proposed. In this project, we propose a secure architecture where EVs and the smart grid can exchange data information for making slots reservation at the charging stations and route planning. Authentication and authorization of EVs or users is essential to guarantee EVs confidentiality and the exchange of information. This implies a request to provide the sensitive information in encrypted mode through security protocols. These procedures are executed after the EV notification process. Besides, we propose a new scheme for planning EVs itineraries. This scheme considers the state of charge of EVs, their starting positions, their destinations and the charging stations available on the road. The system establishes the reservation of the charging slots via optimizing the waiting time at charging stations as well as the energy consumption during EVs journey, from their starting positions to their designated destinations.

The theme of this thesis is a process analysis of the Prague Congress Centre. The purpose of diploma work is to propose more effective running of processes in the company. The theoretical part focuses on business processes, process analysis and graphical languages. Another part deals with company's reservation system and analyzes typical characteristics of reservation systems. The main focus of the thesis is on process analysis of Prague Congress Centre, Inc. Current situation is analyzed and more effective operations which run through the whole company are proposed and evaluated. The emphasis is put on differences evaluation between present and proposed situation and suggestion for change. Another part deals with gaps detection in reservation system which is closely connected with chosen analyzed processes. These gaps, up to certain stage, do not allow effective running of chosen processes.

This dissertation examined personal, cultural, school, and family factors that contribute to the decision of Native American students to remain in school until graduation or to drop out. One hundred eighty-one participants who had either graduated or dropped out of school completed a 140-item questionnaire. Participants lived on the Shoshone-Bannock Indian Reservation located at Fort Hall, Idaho. Factors examined in the survey instrument included substance abuse by self or family members, peer pressure, trouble with the law, self-esteem, teen pregnancy, family structure, socioeconomic status, parents education, academic achievement, teacher attitudes and expectations, school attendance, tribal self-identity and pride, and bilingualism. This research was based on the assumption that issues and processes in Native American education must be addressed by Native people themselves in order for positive change to occur. In addition, the research looked for factors that seem to keep Native Americans in school. The analysis suggested that respondents who were at a higher risk of dropping out of school had a negative self-attitude, frequently skipped school, and had negative attitudes about their teachers' expectations. These results differed significantly from those of Native Americans who had positive self-attitudes, positive attitudes about their teachers' expectations, and positive family influences. Themes of poverty, self-esteem, and teacher attitudes repeatedly surfaced. Graduates frequently reported that positive family expectations (including teachers) kept them in school. This dissertation provides important information for those involved in Native American education. In addition, this dissertation brings together the views of the Native American, specifically the Shoshone-Bannock people, in the journey of education. Together, the review of literature and data collected on the Shoshone-Bannock Indian reservation provide a valuable resource for teachers, parents , and community members now involved, or soon to be involved, in Native American education.
