La première mesure du spectre en phi*_eta du boson Z à 7 TeV a été réalisée dans cette thèse. Cette variable permet de sonder la dynamique de production des Z de façon fine. L’échantillon complet des données enregistrées par ATLAS en 2011 a été utilisé ce qui correspond à 4.7/fb de luminosité intégrée. Les résultats de cette mesure sont publiés dans la Ref. [18] fondé sur la note interne Ref. [69]. La section efficace différentielle de Z->ee en fonction phi*_eta a été mesurée et comparée aux calculs perturbatifs à ordre fixé, avec/sans resommation pour la région des petits phi*_eta. Le code RESBOS fournit la meilleure description des données, cependant il est incapable de reproduire, à mieux de 4%, la forme détaillée de la section efficace mesurée. La section efficace différentielle a également été comparée aux prédictions de différents générateurs Monte Carlo interfacés avec un algorithme de parton shower. Les meilleures descriptions du spectre en phi*_eta mesuré sont données par les générateurs SHERPA et POWHEG+PYTHIA8. La mesure précise de la section efficace différentielle en phi*_eta fournit des informations précieuses pour l’ajustement des codes Monte Carlo. La précision expérimentale typique de cette mesure (~0.5%) est dix fois meilleure que la précision des calculs théoriques et elle est donc aussi précieuse pour contraindre la théorie. La mesure du spectre en ptZ a également été faite pour quantifier l’incertitude systématique de cette mesure en utilisant la grande statistique de l’échantillon de données. Cela permet de comparer deux mesures qui traitent de l’impulsion transverse du boson Z. Dans la plupart du domaine en phi*_eta l’incertitude systématique de la mesure de ptZ est deux fois plus grande que celle de la mesure de phi*_eta. Cette comparaison confirme l’intérêt de la variable phi*_eta. Les résultats présentés dans cette thèse ont beaucoup d’implications pour les études futures. Ajustant les générateurs Monte Carlo en utilisant les résultats de la mesure précise du spectre en phi*_eta minimisera l’incertitude sur leurs paramètres. Une mesure de la section efficace doublement différentielle en ptZ et phi*_eta est intéressante pour mieux comprendre la corrélation entre ces deux variables. La mesure précise du spectre en ptZ utilisant la variable phi*_eta peut être appliquée au spectre en ptW et on sait que des mesures plus fines du ptW sont importante pour une détermination précise de la masse du boson W. De plus, une compréhension précise du spectre en ptZ est importante pour comprendre les propriétés cinématiques de la production du boson de Higgs. / The first measurement of the phi*_eta spectrum of Z bosons at 7 TeV of pp collisions has been studied in this thesis, which is an alternative way to probe the transverse momentum of Z bosons. The full data sample recorded by the ATLAS detector during 2011 run of the LHC was used, which corresponds with 4.7/fb integrated luminosity. The results of this measurement were reported in Ref. [18] supported by the internal note in Ref. [69]. The differential cross section of Z->ee as a function of phi*_eta has been measured and compared to fixed order perturbative QCD calculations with/without a resummation for the low phi*_eta region. Calculations using RESBOS provide the best descriptions of the data. However, they are unable to reproduce the detailed shape of the measured cross section to better than 4%. The differential cross section was also compared to predictions from different Monte Carlo generators interfaced to a parton shower algorithm. The best descriptions of the measured phi*_eta spectrum are provided by SHERPA and POWHEG+PYTHIA8 Monte Carlo event generators. The precise measurement of the differential cross section as a function of phi*_eta provides valuable information for the tuning of MC generators. The typical experimental precision of this measurement (~0.5%) is ten times better than the typical theoretical precision and therefore is valuable to constrain the theoretical predictions further. The ptZ measurement has been also studied to quantify the systematic uncertainty of this measurement using the high statistic data sample. This allows to compare two measurements which both address the physics issues of the Z transverse momentum. In most of the phi*_eta range, the systematic uncertainty of the ptZ measurement is two times larger than the one of the phi*_eta measurement. This comparison confirms the interest for the phi*_eta variable. The measurements presented in this thesis has many implications for future studies. Tuning MC generators using the result of the precise measurement of the phi*_eta spectrum will minimize the uncertainty on the tuned parameters. A double differential cross section measurement as a function of ptZ and phi*_eta is interesting to understand the correlation between ptZ and phi*_eta variables. The precise measurement of the ptZ spectrum using the new variable phi*_eta can be applied to ptZ. More precise measurement of ptZ are important to obtain precise measurements of the W mass. In addition, a precise understanding of the ptZ spectrum is important to understand kinematic properties of Higgs boson production.

La transition alimentaire touche tous les pays émergents avec un développement des pathologies dégénératives liées à l'alimentation. Notre recherche visait à étudier la typologie alimentaire libanaise actuelle sous l'angle de la question suivante: le Liban a-t-il préservé son alimentation traditionnelle ou a-t-il évolué vers une alimentation occidentale ? Une pré-enquête menée au Liban en 2003, a permis d'identifier que la place des plats traditionnels dans l'alimentation libanaise reste importante de nos jours. Cependant, les outils d'enquêtes nécessaires à caractériser de manière fiable et précise les consommations alimentaires n'étaient pas disponibles. Ceci nous a conduits à développer des outils pour évaluer la part de l'alimentation traditionnelle dans la diète libanaise et à évaluer sa contribution à la couverture des besoins nutritionnels. Nous avons construit et validé un cahier de photographies de portions alimentaires, un questionnaire de fréquence alimentaire et une table de composition nutritionnelle correspondant à ces plats. Nous avons ensuite réalisé une enquête sur une sous-population représentative et conclut les points suivants :1- La population libanaise moderne a préservé une place importante à l'alimentation traditionnelle : 57% de la population libanaise consomme plus de 9 plats traditionnels par semaine, soit près de 2 plats par jour.2- Cette alimentation est caractérisée, comme dans la plupart des régions méditerranéennes, par une contribution prépondérante des fruits et légumes (42%), des céréales (34% : pain 14% ; feuilletés 5%) et des légumes secs (7%) dans la ration alimentaire.3- Le régime alimentaire libanais traditionnel est entrain d'être abandonné surtout par les hommes actifs, les étudiants et les personnes célibataires, qui passent la plupart de leur temps hors domicile et sont donc plus susceptibles de consommer une alimentation plus industrielle, indépendamment de l'âge, du niveau d'éducation et de la région de résidence.4- La population libanaise, au travers de la consommation des seuls plats traditionnels dont l'apport calorique dépasse les 75%, a des apports moyens en calories de 2047 kcal/j, des apports énergétiques moyens en glucides de 46%, en protéines de 11% et en lipides de 43% dont 10% d'AGS, 20% d'AGMI et 10% d'AGPI. Elle couvre presque tous ses besoins en vitamines et minéraux.5- La ration alimentaire libanaise présente aujourd'hui une forte tendance à évoluer vers des régimes riches en lipides au détriment des glucides. Ces derniers gardent cependant une place relativement importante dans la ration mais ont changé de nature: autrefois consommés sous forme de céréales complètes, ils le sont aujourd'hui sous forme de céréales raffinées et transformées. En conclusion, le Liban semble être le lieu d'une coexistence entre la tradition et la modernité. Une revalorisation du régime traditionnel encore très présent dans les habitudes alimentaires devrait permettre de ralentir la transition nutritionnelle et améliorer l'état de santé de la population. / All emerging countries are now subjected to a dietary transition accompanied by a development of degenerative pathologies related to human diet. Our research is aimed at investigating the current Lebanese food typology under the following theme: have Lebanon been able to preserve its local traditional diet or have it been affected by the exposure to western diet? A pre-survey administered in Lebanon in 2003, showed that the existence of the traditional dishes in the Lebanese diet remain important till date. However, the absence of reliable and precise tools to conduct surveys aiming to describe food consumptions gave us an incentive to develop such tools. The main purpose of the exercise is to determine the contribution of the traditional Lebanese food to the relative overall intake and to evaluate its contribution in covering the various nutritional needs. For this reason, we developed and validated a photographic atlas of food portions, a food frequency questionnaire and a table of food composition corresponding to the traditional Lebanese dishes. This effort was followed by a survey on a representative sub-population that suggested 5 main findings:1-The modern Lebanese population preserved an important place for the traditional food: 57 % of the Lebanese population consumes more than 9 traditional dishes per week, which means 2 dishes per day.2-This diet is characterized, as in most of the Mediterranean regions, by a dominating contribution of fruits and vegetables (42 %), cereals (34 %: bread 14 %; pastries 5 %) and legumes (7 %) in the daily food ration.3-The traditional Lebanese diet is especially absent from active men, students and the single persons, who spend most of their time out of home and may thus consume industrial food, independently of their age, educational level and the location of their residence.4-The Lebanese population, through the consumption of the only traditional dishes of which the energy intake exceeds the 75 %, has mean energy intake of 2047 kcal/day. The breakdown shows a statistical mean of carbohydrates ranging up to 46 %; 11% of proteins; 43% of lipids; 10 % of SFA, 20 % of MUFA and 10 % of PUFA. The Lebanese population covers almost all their needs in vitamins and minerals.5- The Lebanese daily food ration presents a strong trend today to evolve towards diets rich in lipids on the detriment of carbohydrates. Carbohydrates keep however a place that is relatively important in the ration but with a changed pattern: consumed in the form of wholegrain cereal in the past, they are now replaced by refined and transformed cereal. In conclusion, Lebanon seems to be the place of coexistence between the tradition and the modernity. A valorisation of the still very present traditional diet in the food habits should allow to slow down the nutritional transition and to improve the health of the population.

Em algumas pesquisas, mostra-se que a anotação de informações relacionadas ao contexto no qual uma determinada fotografia foi capturada auxilia na busca das fotografias, sendo as informações mais relevantes para uma pessoa recordar de uma fotografia: a identificação das pessoas que estão presentes na fotografia (Quem); a localização geográfica (Onde); e informações temporais (Quando). Para anotar essas informações, podem ser utilizados mecanismos manuais, automáticos e semiautomáticos. Os mecanismos manuais não possuem muitos adeptos devido ao processo oneroso e tedioso. Os mecanismos automáticos utilizam os algoritmos de análise de conteúdo, sendo o reconhecimento de faces a principal estratégia, a qual só possui bons resultados com faces frontais e sem oclusões. Já os mecanismos de anotação semiautomática, utilizam algoritmos de recomendação de anotações para auxiliar o usuário. Nesta pesquisa, propõem-se algoritmos para a anotação automática e semiautomática de pessoas e eventos em fotografias. Para a anotação de pessoas, utiliza-se o reconhecimento de faces para a anotação automática e informações de contexto mais conteúdo para a geração de listas de sugestões de pessoas para a anotação semiautomática. Para a anotação de eventos, propõe-se um método para a detecção de eventos em coleções pessoais de fotografias e um método para detecção de eventos compartilhados, nos quais as fotografias são capturadas por usuários distintos em um mesmo evento. A partir do método de detecção de eventos compartilhados proposto, pretende-se melhorar a busca de fotografias de um evento em uma rede social, a realização de anotação cruzada e a detecção de inconsistências nas anotações de fotografias. Nos resultados, comprova-se que a ponderação e a filtragem de estimadores para os algoritmos de anotação semiautomática de pessoas presentes nas fotografias baseados em estimadores melhoram os resultados desses algoritmos. Além disso, é possível fazer a detecção de eventos compartilhados em uma rede social utilizando informações de quem, onde e quando das fotografias. / The popularity of digital cameras has created a new problem: how to store and retrieve efficiently a large number of captured and chaotically stored digital photos in multiple locations without annotation. The photo context assists in search of photographs. The most relevant information for a person remember a photograph are: who are present, where and when was captured. To annotate this information, manual, automatic and semiautomatic mechanisms can be used. The manuals mechanisms did not have many fans due to the costly and tedious process. Content analysis and face recognition are the main strategy to automatic mechanisms, which has only front faces with good results and without occlusions. In the semiautomatic annotation, recommendation of annotations are used to assist the user. In this research, we propose algorithms for the automatic and semiautomatic annotation of people and events in photos. For the annotation of people, we use face recognition for automatic annotation and content and context information for generate suggestions from people for semi-automatic annotation. For the annotation of events, we propose a method for detecting events in personal photo collections and a method for detection of shared events, in which the photographs are captured by different users in the same event. The method to detect shared events aims to improve the search of photographs of an event in a social network, conducting cross-annotation and detection of inconsistencies in the annotations of photographs. The results prove that the weighting and filtering algorithms estimators for semi-automatic annotation of persons in photographs based estimators improve the results of these algorithms. Furthermore, it is possible to detect shared events in a social network using information of who, where and when of the photos.

Dissertation focuses on the verification of construction family houses made of concrete shell block with internal thermal insulation system. The construction technology is transferred to the Czech Republic from France. The work focuses on building envelope. The suitability of implementation is assessed on the basis of verification selected thermal technical requirements placed on building envelope. Requirements are specified by legislation in force in the ČR. The verification was performed by using software simulations and measurements on realized buildings. Critical areas of construction technology were identified on the basis software simulations and measurements on site. It was suggested solution, in which critical areas comply the thermal technical requirements. The building envelope was checked also using the thermography imaging on site. Continuous measurement of interior temperature was used to evaluate thermal comfort in the room. In the completed buildings was tested airtightness of the building envelope, which revealed other critical areas of the building envelope. Critical areas are necessary to solve with sufficient care. The economic cost of implementing each variants of exterior walls made of concrete shell block with internal thermal insulation were compared with the economic costs of implementing external walls made of burnt clay hollow blocks and made of burnt clay hollow blocks with external thermal insulation system ETICS. Subsequently, the economic return was calculated for individual variants of external walls made of concrete shell blocks with internal thermal insulation. From the environmental viewpoint was made comparison of production greenhouse gas CO2 and SO2 (cause acid rains) during the life cycle of the individual variations of exterior walls made of concrete shell blocks with system of internal thermal insulation, exterior walls made of burnt clay hollow blocks and burnt clay hollow blocks with external thermal insulation syst
