By modelling an organization’s business processes, it is possible to capture how the organization coordinates the work and resources with the aim of achieving its goals and strategies (Sharp, et al., 2001). Since business processes and goals are intrinsically interdependent, establishing an alignment between the process and the goal domains arises as a natural approach. This thesis reports on a real-life exploratory case study in which we investigated the relationship between the elements of the enterprise (modeled in the ARIS framework) and the goals (modeled in the Tropos framework and modeling language) which are attained by these elements. The case study has been conducted in the Rheumatology Department of a University Hospital in Brazil. In the course of the case study, we have identified the need of splitting this effort into three phases: the elicitation phase (in which goal models and business process models are captured from the organizational domain), the harmonization phase (in which the goal domain is structured for alignment according to the business processes structures that will support it) and the alignment phase (in which the relationships between the goal domain and the elements of the organizational domain are established). In order to investigate the relation between goals and enterprise elements, we propose an ontological account for both architectural domains. We recognize the importance in considering the business process as the means for implementing an enterprise’s strategy, but we do not exclude the remaining enterprise elements. Furthermore, we are concerned with both the identification of the relationships and with a classification for their nature.

An entity capable of assessing its and others action capabilities possess the power to predict how the involved entities may change their world. Through this knowledge and higher level of situation awareness, the assessing entity may choose the actions that have the most suitable effect, resulting in that entity’s desired world state. This thesis covers aspects and concepts of an arbitrary planning system and presents a threat analyzer architecture built on the novel planning system Goal-Oriented Action Planning (GOAP). This planning system has been suggested for an application for improved missile route planning and targeting, as well as being applied in contemporary computer games such as F.E.A.R. – First Encounter Assault Recon and S.T.A.L.K.E.R.: Shadow of Chernobyl. The GOAP architecture realized in this project is utilized by two agents that perform action planning to reach their desired world states. One of the agents employs a modified GOAP planner used as a threat analyzer in order to determine what threat level the adversary agent constitutes. This project does also introduce a conceptual schema of a general planning system that considers orders, doctrine and style; as well as a schema depicting an agent system using a blackboard in conjunction with the OODA-loop.

L’adaptation de maillage est un outil puissant pour l’obtention de simulations aérodynamiques précises à coût limité. Dans le cas particulier des simulations visant au calcul de fonctions aérodynamiques (efforts, moments, rendements...), plusieurs méthodes dites de raffinement ciblé (ou, en anglais, « goal-oriented ») basées sur le vecteur adjoint de la fonction d’intérêt ont été proposées. L’objectif de la thèse est l’extension d’une méthode de ce type basée sur la dérivée totale dJ/dX de la grandeur aérodynamique d’intérêt, J, par rapport aux coordonnées du maillage volumique, X. Les trois méthodes usuelles de calcul de gradient discret – la méthode de différentiation directe, la méthode adjointe-"paramètres" et la méthode adjointe-"maillage" évaluant dJ/dX – ont tout d’abord été étudiées et codées dans le logiciel elsA de l’ONERA pour des maillages non-structurés, pour des écoulements compressibles de fluide parfait et des écoulements laminaires. La seconde étape du travail a consisté à créer un senseur local θ basé sur dJ/dX qui identifie les zones du maillage volumique où la position des nœuds a une forte incidence sur l’évaluation de la fonction J. Ce senseur sert d’indicateur pour l’adaptation de différents maillages, pour différents régimes d’écoulement (subsonique, transsonique, supersonique), pour des configurations d’aérodynamique interne (aube et tuyère) et externe (profil d’aile). La méthode proposée est comparée à une méthode de raffinement ciblée très populaire (Venditti et Darmofal, 2001) et à une méthode de raffinement basée sur les caractéristiques de l’écoulement (ou, en anglais, « feature-based ») ; elle conduit à des résultats très satisfaisants. / Mesh adaptation is a powerful tool to obtain accurate aerodynamic simulations with limited cost. In the specific case of computation of aerodynamic functions (forces, moments, efficiency ...), goal-oriented methods based on the adjoint vector have been proposed. The aim of the thesis is the extension of a method of this type based on the total derivative dJ/dX of the aerodynamic output of interest, J, with respect to the volume mesh coordinates, X. The three common methods for calculating discrete gradient – the direct differentiation method, the parameter-adjoint method and mesh-adjoint method evaluating dJ/dX – have been studied first and coded in the elsA ONERA software for unstructured grids, for compressible inviscid and laminar flows. The second part of this work was has been to define a local sensor θ based on dJ/dX in order to identify zones where the volume mesh nodes position has a strong impact on the evaluation of the function J. This sensor is the selected indicator for different mesh adaptations for different flow regimes (subsonic, transonic, supersonic) for internal (blade and nozzle) and external (wing profile) aerodynamic configurations. The proposed method is compared to a well-known goal-oriented method (Darmofal and Venditti, 2001) and to a feature-based method ; it leads to very consistent results. very consistent results.

Mobile widgets now form a new paradigm of simplified web. Probably, the best experience of the Web is when a user has a widget for every frequently executed task, and can execute it anytime, anywhere on any device. However, the current method of programmatically creating personally relevant mobile widgets for every user does not scale. Creation of these mobile web widgets requires application programming as well as knowledge of web-related protocols. Furthermore, these mobile widgets are also limited to smart phones with data connectivity and such smart phones form just about 15% of the mobile phones in India. How do we make web accessible on devices that most people can afford? How does one create simple relevant tasks for the numerous diverse needs of every person? In this thesis, we attempt to address these issues and propose a new method of web simplification that enables an end-user to create simple single-click widgets for a complex personal task - without any programming. The proposed solution enables even low-end phones to access personal web tasks over SMS and voice. We propose a system that enables end users to create personal widgets via programming-by-browsing. A new concept called Tasklets to represent a user’s personal interaction, and a notion of programming over websites using a Web Virtual Machine are presented. Ensuring correct execution of these end user widgets posed interesting problems in web data mining and required us to investigate new methods to characterize and semantically model browser-based interactions. In particular, an instruction set for programming over web sites, new domain-specific similarity measures using ontologies, algorithms for frequent-pattern mining of web interactions and change detection with a proof of its NP-completeness are presented. A quantitative metric to measure the interaction complexity of web browsing and a method of classifying relational data using semantics hidden in the schema are introduced as well. This new web architecture to enable multi-device access to user's personal tasks over low-end phones was piloted with real users, as a solution named SiteOnMobile, and has received very positive response.

La sécurité-innocuité est une propriété émergente des systèmes critiques de sécurité (SCS), notamment les systèmes ferroviaires. Cet aspect émergent complexifie leur processus du développement et nécessite un raisonnement judicieux permettant de diminuer les dangers. Cette thèse propose une approche ontologique qui intègre les activités de sécurité dès les premières phases de conception des SCS. Ce cadre structuré offre une harmonisation sémantique entre les domaines impliqués, tels que l'ingénierie de sécurité et l'Ingénierie des Exigences Dirigée par les Buts (IEDB). La logique métier intégrée dans cette approche est validée par des cas d'étude ferroviaires d'accidents réels et d'une mission télé-opérée. Dans un premier temps, nous avons proposé une ontologie d'analyse dysfonctionnelle appelée DAO et fondée sur l'ontologie de haut niveau UFO. DAO considère les aspects sociaux-techniques et environnementaux des SCS et intègre les différents types de fautes et de propriétés cognitives liés respectivement aux défaillances techniques et aux erreurs humaines. Le modèle conceptuel de DAO est exprimé en OntoUML et formalisé en langage OWL afin de fournir un support de raisonnement. Ensuite, un pont sémantique est établi entre les mesures de sécurité, les buts de sécurité et les exigences de sécurité par le développement d'une ontologie de gestion de sécurité orientée-but, appelée GOSMO. La gestion des décisions de sécurité s’appuie sur la réinterprétation du modèle de contrôle d'accès Or-Bac d'un point de vue sécurité-innocuité. Afin d'assurer la cohérence globale des exigences, GOSMO permet de structurer la gestion des évolutions des exigences et leur traçabilité. / Safety is an emergent property of safety critical systems (SCS), including railway systems. This emergent aspect exacerbates their development process and requires a thorough reasoning to reduce hazards. This thesis proposes an ontological approach that integrates safety activities from the early design stages of SCS. This structured framework provides a semantic harmonization between the involved domains, such as safety engineering and Goal Oriented Requirements Engineering (GORE). The business logic integrated in this approach is validated by real rail accident scenarios and a remotely operated task. At first, we proposed a dysfunctional analysis ontology called DAO and based on the high-level ontology UFO. DAO considers the socio-technical and environmental aspects of SCS and integrates the different types of faults and cognitive properties that are respectively related to technical failures and human errors. The DAO conceptual model is expressed in OntoUML and formalized in OWL language in order to provide a reasoning support. Then, a semantic bridge is established between safety measures, safety goals and safety requirements through the development of a goal-oriented security management ontology, called GOSMO. The management of safety decisions is based on the reinterpretation of the Or-Bac access control model from a safety point of view. In order to ensure the overall consistency of requirements, GOSMO allows structuring the management of requirements changes and their traceability

Disertační práce Porovnávání středoevropských jazyků: za horizont strukturních rysů a lexikálních přejímek se soustředí na zhodnocení a přehodnocení přístupu k výzkumu jazyků střední Evropy. Hlavním cílem předkládané práce je (1) podat přehled dosavadních poznatků o porovnávání středoevropských jazyků, (2) na jeho základě naznačit možné nové směřování němu přispět. Druhá kapitola práce se věnuje areálové lingvistice, jakožto disciplíně zaměřené na výzkum podobnosti a konvergence geograficky blízkých jazyků, a zejména jejímu ústřednímu pojmu . Představuje okolnosti jeho vzniku, jeho různé definice a jeho kritické (pře)hodnocení pracích současných areálových lingvistů. Třetí kapitola sumarizuje výzkum středoevropských jazyků: různé koncepce středoevropského (popř. dunajského) jazykového svazu vzájemné vlivy lexika a frazeologie těchto jazyků a popisy situací jazykového kontaktu v areálu. Tento přehled ukázal, že hlavními doménami porovnávání jazyků areálu dosud byly strukturní rysy a lexikální přejímky a kalky. Novější vývoj lingvistiky, jak je naznačeno ve čtvrté kapitole, však operuje rovněž s jazykovými jednotkami, které překlenují a relativizují -lexikon. Nabízí se tedy, aby se rovněž komparativní výzkum středoevropských jazyků soustředil na tyto jevy zahrnutelné pod pojem idiomatičnosti. Pátá kapitola...

Les systèmes de dialogues sont à même de révolutionner l'interaction entre l'homme et la machine. Pour autant, les efforts pour concevoir des agents conversationnels se sont souvent révélés infructueux, et ceux, malgré les dernières avancées en apprentissage profond et par renforcement. Les systèmes de dialogue palissent de devoir opérer sur de nombreux domaines d'application mais pour lesquels aucune mesure d'évaluation claire n'a été définie. Aussi, cette thèse s'attache à étudier les dialogues débouchant sur un objectif clair (goal-oriented dialogue) permettant de guider l'entrainement, et ceci, dans des environnements multimodaux. Plusieurs raisons expliquent ce choix : (i) cela contraint le périmètre de la conversation, (ii) cela introduit une méthode d'évaluation claire, (iii) enfin, l'aspect multimodal enrichie la représentation linguistique en reliant l'apprentissage du langage avec des expériences sensorielles. En particulier, nous avons développé GuessWhat?! (Qu-est-ce donc?!), un jeu imagé coopératif où deux joueurs tentent de retrouver un objet en posant une série de questions. Afin d’apprendre aux agents de répondre aux questions sur les images, nous avons développés une méthode dites de normalisation conditionnée des données (Conditional Batch Nornalization). Ainsi, cette méthode permet d'adapter simplement mais efficacement des noyaux de convolutions visuels en fonction de la question en cours. Enfin, nous avons étudié les tâches de navigation guidée par dialogue, et introduit la tâche Talk the Walk (Raconte-moi le Chemin) à cet effet. Dans ce jeu, deux agents, un touriste et un guide, s'accordent afin d'aider le touriste à traverser une reconstruction virtuelle des rues de New-York et atteindre une position prédéfinie. / While dialogue systems have the potential to fundamentally change human-machine interaction, developing general chatbots with deep learning and reinforce-ment learning techniques has proven difficult. One challenging aspect is that these systems are expected to operate in broad application domains for which there is not a clear measure of evaluation. This thesis investigates goal-oriented dialogue tasks in multi-modal environments because it (i) constrains the scope of the conversa-tion, (ii) comes with a better-defined objective, and (iii) enables enriching language representations by grounding them to perceptual experiences. More specifically, we develop GuessWhat, an image-based guessing game in which two agents cooper-ate to locate an unknown object through asking a sequence of questions. For the subtask of visual question answering, we propose Conditional Batch Normalization layers as a simple but effective conditioning method that adapts the convolutional activations to the specific question at hand. Finally, we investigate the difficulty of dialogue-based navigation by introducing Talk The Walk, a new task where two agents (a “tourist” and a “guide”) collaborate to have the tourist navigate to target locations in the virtual streets of New York City.

Abstract. Autonomous agents, also known as AI agents, are staples in modern video games. They take a lot of roles, everything from being quest-givers in roleplaying games, to opposing forces in action- and shooter games. Crafting an AI that is not only easy to create, but also retains humanlike and believable behavior, has always represented a challenge to the development industry, and has in several cases ended up with open world games using AI systems that limit the AI agents to simple moving patterns. In this thesis, a form of AI systems more commonly used in simulation games such as The Sims video game series, are taken and implemented in an environment that could possibly be seen in an open world game. After the implementation, a set of tests were performed on a group of testers which resulted in the insight that a majority of the testers, when asked to compare their experience to other games, found this implementation to feel more lifelike and realistic.

Bakgrund och problemdiskussion: Inom organisationer är vd:n ett hett och debatterat samtalsämne när det kommer till verksamhetsstyrning. Inom små till medelstora verksamheter är det inte ovanligt att ägaren är både ägare och vd för verksamheten, vilket betecknas som ett ägarlett företag. När ett företag går från ett ägarlett styre till en extern vd kan det ha en stor inverkan på verksamheten. Ett byte av vd innebär att en ny person kommer att bestämma hur verksamhetens styrning ska utformas och implementeras. Fortsättningsvis innebär det ett stort steg för ägaren när den ska frånsäga sin vd-position och lämna över till en extern vd. Det finns två olika teorier som förklarar relationen mellan ägare och vd. Agentteorin, som antar att människor agerar utifrån sitt eget intresse, och stewardshipteorin, som utgår från att människor agerar utifrån verksamhetens bästa. Syfte: Syftet med studien är att undersöka om verksamhetsstyrning förändras i samband med att en extern vd intar vd-rollen i ett tidigare ägarlett företag. Ytterligare kommer studien att undersöka hur ägaren och den externa vd:n ser på skiftet när en extern vd intar vd-rollen utifrån agentteorin och stewardship. Metod: Studien är en fallstudie som undersöker två företag som har genomgått ett skifte från ägarlett styre till externt styre. Denna studie kompletteras med inblick och erfarenhet från rekryterare inom högre befattningar. Studien utgår från en kvalitativ forskningsstrategi, med induktiva forskningsval som har abduktiva anslag. Det empiriska materialet har samlats in via sju stycken respondenter via semistrukturerade intervjuer. Slutsats: De slutsatser som kan dras från studien är att verksamhetsstyrningen förändras till att bli mer målstyrd när företaget går från ett ägarlett styre till att en extern person intar vd-rollen. Både ägare och vd från respektive verksamhet visar en skiftning av både opportunistiskt beteende och beteende som liknar en ‘steward’. Det innebär att det inte finns ett svart-vitt beteende avseende om individerna agerar efter sitt eget bästa eller efter verksamhetens bästa. Deras synsätt och agerande uppvisar en kombination av båda teorierna i samband med att verksamheten blir mer professionell, strategisk och målstyrd. / Background: Within organisations, the CEO is a well-known and debated subject when it comes to corporate governance in small to medium-sized enterprises (SMEs). When a company moves from an owner-led governance to an external CEO, it can have a major impact on the business. An alteration in the role of CEO would allow for a change in the governance of the business, through potential new individualistic implementations and structural decisions. Furthermore, it is a largely significant step for the owner to relinquish the position of CEO to an external individual. There are two different theories to explain the relationship between owners and CEOs. Agent theory, which assumes that people act in their own interest, and stewardship theory, which assumes that people act in the best interests of the business. Purpose: The purpose of the thesis is to investigate whether corporate governance changes when an external person is appointed CEO in a previously owner-managed company. Furthermore, this thesis will investigate how both the owner and the external CEO perceive the transition when the role of CEO is assigned to an external individual based on agent theory and stewardship theory. Method: The study is a case study examining two case companies that have experienced a shift from owner-led governance to external governance, along with the insight and experience of two senior recruiters. The study is based on a qualitative research strategy, with specific attention to inductive research choices and abductive approaches. The empirical material has been collected via semi-structured interviews and the involvement of seven respondents. Conclusion: The conclusion that can be drawn from the thesis is that the corporate governance changes and becomes more goal-oriented when an external person is the CEO. Both owners and CEOs from each business have a tendency towards both opportunistic and steward-like behavior. This means that there is no specific behavior regarding whether they act in their own best interests or in the best interests of the business. Their views and actions reflect a combination of both theories as the organisation becomes more professional, strategic and goal- oriented.
