The aim of the present thesis is to give a comparision on sex determination of phenotypically undifferentiated birds species focused on the Long-eared Owl (Asio otus). Compared to other species of owls is relatively a few researches on the Long-eared Owl and researches on sex differences have not led to the quantified results yet. Attention is focused on characteristics and mechanisms of birds coloration. This work includes the methods and results of colour perception and interpretation in sexual dimorphism. It focuses primarily on the differences in color of certain parts of the bird, such as the alula, secondary remiges and lower part of the wing. For those pieces is further evaluating color differences in sex and proposes solutions that could help in further researches on sex determination of the Long-eared Owl.

My thesis deals with ecology and diet of the Long - eared Owl (Asio otus). The study area a wintering place is situated near the town of Kladno. 1) The hypothesis that a high snow cover has an influence on the Long-eared Owl diet has been confirmed. 3) The thesis deals with the determination methods of small vertebrate species in Long - eared Owl's diet. The work deals with postcranial skelet as well. There was compilled the method of the sex determination in Common vole (Microtus arvalis). The sex determination was based on the morphological differences of the pelvic bones. The results (sex ratio) had been statistically tested and as such found significant. 2) There were also analyzed the skeletal remnants of the pelvic bones in the pellets. The study of the pelvic bones was carry out in order to find expected seasonal changes in the sex ratio in a dominant prey Common vole (Microtus arvalis). That hypothesis was not confirmed. Keywords: Long-eared owl (Asio otus), diet, postcranial skeleton, pelvic bones

A collection of eight nonfiction stories by Missy Bowen about the Minnesota State Fair, owls, winter, summer, stairs, lumber, and the rock and roll life.

This diploma thesis deals with the monitoring of the Long-eared Owl (Asio otus) on the wintering grounds in Kladno Kročehlavy between 2015 and 2017. The monitoring is focused on spatial activity linked to food sources and food analysis. The research aimed at finding out whether the maximum distance of night overflight is within five kilometers from the night shelter. Another focus was on the discovery of the variability of the food supply in relation to the weather over the past 10 years and the comparison of the data with the results of the already published works. Several methods were used in the research. Method of observation, capture into impact ornithological nets, ringing, collection and analysis of pellets and modern method of GPS telemetry. Using mentioned methods, it was found that the maximum distance of overflights linked to food sources is not only within five kilometers from the night shelter. These distances may vary in length. The research managed to track the overflight less than 30 kilometers away. Further findings on the content of food supply and weather showed that there has been only slight variation in the occurrence of the main boar loot in the last ten years.

In most ICUs, monitoring and recording vital signs are performed in a manual fashion and in predefined time instants. The records of measurements of vital signs in ICUs are generally written on preprinted forms, and a health professional has to re-sort those forms when he wants to get some information about the clinical state of a patient. Besides, when an abnormal measurement of vital sign is detected, a multiparameter monitor triggers audible alarms, and that alarm may not be prompted detected by the medical staff, depending on the workflow within an ICU. In that sense, this work proposes a knowledge representation model of monitoring of vital signs of patients in ICUs. The model proposed exploits the expressiveness and the formality of ontologies, rules and semantic web technologies. This promotes the consensual comprehension, the sharing and the reuse of vital signs of patients. The aim is to develop context-aware applications for monitoring human vital signs, including the storage, query support and semantic alarms triggering. / O monitoramento de sinais vitais de pacientes em unidades de terapia intensiva (UTI) é uma atividade que faz parte da rotina de vários profissionais da área da Saúde, envolvendo médicos, enfermeiros, técnicos e auxiliares de enfermagem. Em várias UTIs, o acompanhamento e o registro dos monitoramentos de sinais vitais são realizados de forma manual e em instantes de tempo pré-definidos. Nesse cenário, os registros das medições dos sinais vitais são escritos em formulários pré-impressos, e quando um profissional da saúde deseja obter alguma informação sobre o estado clínico de um paciente, ele tem que recorrer a esses formulários. Além disso, quando ocorre alguma anormalidade no monitoramento do sinal vital do paciente, um monitor multiparamétrico emite alarmes sonoros e, dependendo do fluxo de trabalho dentro da UTI, esse alarme pode não ser percebido prontamente pela equipe médica. Nesse sentido, este trabalho propõe um modelo de representação do conhecimento relativo ao monitoramento de sinais vitais de pacientes em UTIs. O modelo proposto utiliza o potencial de expressividade e formalidade de ontologias, regras e tecnologias correlatas da Web Semântica, o que promove a compreensão consensual, o compartilhamento e a reutilização de informações de sinais vitais de pacientes. Com esse modelo, espera-se também viabilizar o desenvolvimento de aplicações sensíveis a contexto que envolvem o monitoramento de sinais vitais humanos, com armazenamento, consultas e produção de alarmes em casos de anormalidades detectadas nas medições desses sinais.

Les travaux de recherche développés dans cette thèse, définissent une approche d'évolution d'ontologie Onto-Evoal (Ontology Evolution-Evaluation) qui s'appuie sur une modélisation de patrons de gestion de changement CMP (Change Management Patterns). Ces patrons spécifient des classes de changements, des classes d'incohérences et des classes d'alternatives de résolution. Sur la base de ces patrons et des relations sémantiques entre eux, un processus automatisé permettant de conduire l'application des changements tout en maintenant la cohérence de l'ontologie évoluée a été développé. L'approche intègre également une activité d'évaluation basée sur un modèle de qualité d'ontologie qui a été défini. Ce modèle est employé pour guider la gestion des incohérences en évaluant l'impact des résolutions proposées sur le contenu et l'usage de l'ontologie à travers un ensemble de métriques quantitatives et ce, afin de choisir une résolution qui préserve la qualité de l'ontologie évoluée. La gestion des changements étant fortement liée au modèle dans lequel est représentée l'ontologie, nous nous sommes focalisés sur le langage OWL en tenant compte de l'impact des changements sur la cohérence logique de l'ontologie telle que spécifiée dans la couche OWL DL. Les principales contributions de l'approche résident dans la modélisation des patrons de gestion de changement guidant le processus d'évolution, l'intégration de l'évaluation de la qualité pour optimiser la résolution des changements et la modélisation formelle et explicite du journal d'évolution.

In today&#039 / s world, composite web services are widely used in service oriented computing, web mashups and B2B Applications etc. Most of these services are composed manually. However, the complexity of manually composing web services increase exponentially with the increase in the number of available web services, the need for dynamically created/updated/discovered services and the necessity for higher amount of data bindings and type mappings in longer compositions. Therefore, current highly manual web service composition techniques are far from being the answer to web service composition problem. Automatic web service composition methods are recent research efforts to tackle the issues with manual techniques. Broadly, these methods fall into two groups: (i) workflow based methods and (ii) methods using AI planning. This thesis investigates the application of AI planning techniques to the web service composition problem and in particular, it proposes the use of the abductive event calculus in this domain. Web service compositions are defined as templates using OWL-S (&quot / OWL for Services&quot / ). These generic composition definitions are converted to Prolog language as axioms for the abductive event calculus planner and solutions found by the planner constitute the specific result plans for the generic composition plan. In this thesis it is shown that abductive planning capabilities of the event calculus can be used to generate the web service composition plans that realize the generic procedure.

In recent years, web services have become an emerging technology for communication and integration between applications in many areas such as business to business (B2B) or business to commerce (B2C). In this growing technology, it is hard to compose web services manually because of the increasing number and compexity of web services. Therefore, automation of this composition process has gained a considerable amount of popularity. Automated web service composition can be achieved either by generating the composition plan dynamically using given inputs and outputs, or by locating the correct services if an abstract process model is given. This thesis investigates the former method which is dynamicly generating the composition by using the abductive lanning capabilities of the Event Calculus. Event calculus axioms in Prolog language, are generated using the available OWL-S web service descriptions in the service repository, values given to selected inputs from ontologies used by those semantic web services and desired output types selected again from the ontologies. Abductive Theorem Prover which is the AI planner used in this thesis, generates composition plans and execution results according to the generated event calculus axioms. In this thesis, it is shown that abductive event calculus can be used for generating web services composition plans automatically, and returning the results of the generated plans by executing the necessary web services.

In this thesis, a web service composition and execution framework is presented for semantically annotated web services. A monolithic approach to automated web service composition and execution problem is chosen, which provides some benefits by separating the composition and execution phases. An AI planning method using a logical formalism called Event Calculus is chosen for the composition phase. This formalism allows one to generate a narrative of actions and temporal orderings using abductive planning techniques given a goal. Functional properties of services, namely input/output/precondition/effects(IOPE) are taken into consideration in the composition phase and non-functional properties, namely quality of service (QoS) parameters are used in selecting the most appropriate solution to be executed. The repository of OWL-S semanticWeb services are translated to Event Calculus axioms and the resulting plans found by the Abductive Event Calculus Planner are converted to graphs. These graphs can be sorted according to a score calculated using the defined quality of service parameters of the atomic services in the composition to determine the optimal solution. The selected graph is converted to an OWL-S file which is executed consequently.

Nous appelons Bases de Données à Base Ontologique (BDBO), les bases de données qui contiennent à la fois des données et des ontologies qui en décrivent la sémantique. Dans le contexte du Web Sémantique, de nombreuses BDBO associées à des langages qui permettent d'interroger les données et les ontologies qu'elles contiennent sont apparues. Conçus pour permettre la persistance et l'interrogation des données Web, ces BDBO et ces langages sont spécifiques aux modèles d'ontologies Web, ils se focalisent sur les ontologies conceptuelles et ils ne prennent pas en compte la structure relationnelle inhérente à des données contenues dans une base de données. C'est ce triple problème que vise à résoudre le langage OntoQL proposé dans cette thèse. Ce langage répond au triple problème évoqué précédemment en présentant trois caractéristiques essentielles qui le distinguent des autres langages proposés : (1) le langage OntoQL est indépendant d'un modèle d'ontologies particulier. En effet, ce langage est basé sur un noyau commun aux différents modèles d'ontologies et des instructions de ce langage permettent de l'étendre, (2) le langage OntoQL exploite la couche linguistique qui peut être associée à une ontologie conceptuelle pour permettre d'exprimer des instructions dans différentes langues naturelles et (3) le langage OntoQL est compatible avec le langage SQL, permettant ainsi d'exploiter les données au niveau logique d'une BDBO, et il étend ce langage pour permettre d'accéder aux données au niveau ontologique indépendamment de la représentation logique des données tout en permettant d'en manipuler la structure.
