This master's thesis deals with the creation of an extension to the existing information system NLPIS. A part of solution is the creation and maintenance of automatically generated pages for projects in the MediaWiki application. The data will be generated into the MediaWiki from database NLPIS information system and e-mail communications.

Over the past years, many software industries have adapted the Software Product Line(SPL) as a paradigm that empowers software reuse by exploiting software similarities and managing variabil- ities to enable high-quality deliverables with a shorter time to market. Nevertheless, the lifecycle of SPL development often faces complex tasks. Creating a specific product from the product family is the main challenge. One way towards product realization is through configuration files. Still, manually creating configuration files for each product is an error-prone and time-consuming activ- ity. Therefore, this thesis proposes a variability modeling approach that shall enable an automatic generation of the configuration files for a single product. We conduct a thorough investigation on how to model variability to support automatic generation of the configuration files, introduce four essential decisions related to variability expression, features, constraints and configuration transformation, and present a number of alternative solutions to these decisions. Moreover, we identify evolution scenarios of SPL and evaluate the decisions concerning the scenarios. Finally, a validation of the approach in an industrial case study provided by Bombardier Transportation is presented.

Aplicativos simples e utilizados durante um curto período de tempo são cada vez mais comuns nos dispositivos móveis. Eles perdem a utilidade uma vez que seu objetivo específico é atingido. Porém, consomem memória e processamento do dispositivo, além de seu desenvolvimento consumir recursos humanos e tecnológicos. Para minimizar esses problemas, este trabalho apresenta uma nova abordagem para geração e controle desse tipo de aplicativo por meio de uma nova arquitetura e modelo de ciclo de vida para aplicações de curta duração. A abordagem permite que os aplicativos sejam gerados automaticamente e possam ser excluídos ou gerenciados de acordo com a vontade do usuário ou por outros critérios pré-estabelecidos (e.g., por tempo transcorrido ou por localização). A arquitetura e modelos desenvolvidos foram utilizados em três aplicativos típicos com funcionalidades básicas, layout trivial e processamento leve. Essa validação demonstrou que a abordagem atende às necessidades de aplicativos em diferentes domínios (restaurantes, shoppings e eventos) e pode ser aplicado em situações com diferentes restrições de tempo e localização / Simple applications that are used over a short period of time are becoming increasingly popular on mobile devices. They lose their usefulness once their specific goal is achieved. However, they consume memory and processing of the device; furthermore, its development consume human and technological resources. To minimize these problems, this work presents a new approach for generation and control of this type of application by means of a new architecture and life cycle model for short lived applications. The approach allows applications to be automatically generated, excluded or managed according to the user\'s wishes or other pre-established criteria (e.g., by time elapsed or by location). The architecture and models developed were used in three typical applications with basic functionalities, trivial layout and light-weight processing. This validation demonstrated that the approach addresses the needs of applications in different domains (restaurants, malls and events) and can be applied in situations with different time and location constraints

A proposal for the spinning reserve assessment and allocation for El Salvador¡¦s Deregulated Electricity Market is formulated. Traditionally, the Independent System Operator calculates the spinning reserve as percentage of the forecast demand. And Automatic Generation Control (AGC) is allocated based on the partition factor. The reserve calculation neither reflects consistency achieving its main objective, reliability, nor is optimum performance control reached by the allocating mechanism. In the proposed method, the spinning reserve is estimated taking into account the generators outage ratio and AGC is allocated based on the North American Electric Reliability Corporation¡¦s Control Performance Standard-1. The allocation problem is solved with an improved Particle Swarm Optimization algorithm with a technique to modify the inertial factor on each iteration. The proposed method exhibits better results and it matches the Salvadorian technical requirements and market characteristics.

Over the last decade the increase in penetration of wind power and its variable nature has begun to add considerable stress to and threatened the stability of the nation's grid. In order to continue growth wind farms will need to have the ability to participate in the same grid frequency regulation as traditional generating sources. The goal of this research is to explore the use of energy storage devices to provide wind farms with a method to regulate their power output and the grid frequency. Using energy storage, this research aims to allow wind farms to participate in automatic generation control (AGC). Software simulations were performed to design an advanced energy storage controller that will allow maximum participation in AGC. A comprehensive in-lab grid was constructed to produce experimental results for this work and was used to evaluate the performance of the advanced energy storage controller. The first stage of this research aims to use super-capacitors to balance rapid excursions in frequency and wind power output while the second stage of this research will preliminarily explore the use of a zinc-bromine flow cell battery for medium-scale, sustained excursions in frequency and wind power output. Results show that wind farms are capable of participation in AGC with the addition of an energy storage device, but the amount of participation is heavily reliant on the amount of energy storage available. / Graduation date: 2012

Dans cette thèse, nous abordons le problème de la génération automatique de contenu graphique avec un haut niveau de détails pour la génération de mondes. Dans cette quête du réalisme, les principaux verrous scientifiques et techniques sont : la gestion des masses de données géométriques nécessaires à la création de variétés d'objets naturels, la prise en compte des interactions en les différents objets et le contrôle utilisateur.Notre approche s'appuie sur un modèle volumique original et unificateur permettant de représenter les différents matériaux d'un terrain. Nous proposons un ensemble d'algorithmes de haut niveau, combinant des étapes de simulation pour assurer la plausibilité physique et le réalisme visuel à des techniques de génération procédurale permettant de gérer efficacement la complexité. Nos algorithmes permettent ainsi de sculpter des terrains complexes avec des grottes ou des surplombs et de générer des routes avec des tunnels et des ponts permettant le franchissement d'obstacles naturels. / In this thesis, we address the problem of automatic generation of graphical content with a high level of detail for the generation of worlds. In this quest for realism, the major scientific and technical challenges include: managing the mass of geometric data needed to create varieties of natural objects, taking into account interactions with the various objects and user control.Our approach is based on an original volumetric model for representing and unifying the different materials of land. We offer a range of high-level algorithms, combining simulation steps to ensure physical plausibility and visual realism, and procedural generation techniques to effectively manage complexity. Our algorithms are used to sculpt and complex terrain with caves and overhangs and generate roads with tunnels and bridges to cross natural barriers.

The vision of automated driving demands a highly available system, especially in safety-critical functionalities. In automated driving when a driver is not binding to be a part of the control loop, the system needs to be operational even after failure of a critical component until driver regain the control of vehicle. In pursuit of such a fail-operational behavior, the developed design process with software redundancy in contrast to conventional dedicated backup requires the support of automatic configurator for scheduling relevant parameters to ensure real-time behavior of the system. Multiple implementation methods are introduced to provide an automatic service which also considers task criticality before assigning task to the processor. Also, a generic method is developed to generate adaptation plans automatically for an already monitoring and reconfiguration service to handle fault occurring environment.

The goal of this thesis is to design and implement a program capable of automatically generating synthetic images of eye retinas. The generated images should be similar to those of real retinas, which are hard to obtain, so they could be used for development of various algorithms, which work with eye retina images in their place. This thesis describes anatomic properties of the eye retina, ways to take images of it and also usage of eye retina recognition in biometric and medicinal applications. Design of the program and the way in which individual parts of the retina are assembled together into the final image is also explained in this thesis. These individual parts are created using procedural textures in separate layers of the image. Next chapter of this work describes implementation details of the program. The conclusion then experimentally verifies suitability of the generated images for algorithmic processing.

La reconnaissance de la langue des signes française (LSF) comme une langue à part entière en 2005 a créé un besoin important de développement d’outils informatiques pour rendre l’information accessible au public sourd. Dans cette perspective, cette thèse a pour cadre la modélisation linguistique pour un système de génération de la LSF. Nous présentons dans un premier temps les différentes approches linguistiques ayant pour but la description linguistique des langues des signes (LS). Nous présentons ensuite les travaux effectués en informatique pour les modéliser.Dans un deuxième temps, nous proposons une approche permettant de prendre en compte les caractéristiques linguistiques propres au LS tout en respectant les contraintes d’un processus de formalisation. En étudiant des liens entre des fonctions sémantiques et leurs formes observées dans les corpus LSF, nous avons identifié plusieurs règles de production. Nous présentons finalement le fonctionnement des règles comme étant un système susceptible de modéliser un énoncé entier en LSF. / The recognition of French Sign Language (LSF) as a natural language in 2005 has created an important need for the development of tools to make information accessible to the deaf public. With this prospect, this thesis aims at linguistic modeling for a system of generation of LSF. We first present the different linguistic approaches aimed at describing the sign language (SL). We then present the models proposed in computer science. In a second step, we propose an approach allowing to take into account the linguistic properties of the SL while respecting the constraints of a formalisation process.By studying the links between semantic functions and their observed forms in LSF Corpora, we have identified several production rules. We finally present the rule functioning as a system capable of modeling an entire utterance in LSF.
