Le programme de physique de l'expérience ATLAS auprès de l'accélérateur LHC au CERN couvre un vaste domaine allant de la physique du Modèle Standard, avec la recherche d'un boson de Higgs, à la recherche de nouvelle physique (comme la recherche de super-symétrie ou de dimensions supplémentaires). Cette thèse s'oriente selon deux axes principaux. Elle présente premièrement des études liées à l'électronique de calibration et d'acquisition des signaux issus du calorimètre électromagnétique à argon liquide du détecteur ATLAS. Deuxièmement, elle présente des études menées dans le cadre de la recherche d'un boson de Higgs du Modèle Standard dans sa désintégration en deux photons : l'un des canaux de recherche les plus importants dans la région de basse masse favorisée par des mesures de précision et des prédictions théoriques. Ces études portent en particulier sur la reconstruction et l'utilisation des photons convertis en paires électron-positron dans le but d'améliorer le potentiel de découverte du boson de Higgs dans ce canal de désintégration. D'autres aspects liés à la validation du code de simulation rapide du détecteur ATLAS y sont également décrits, concernant ses performances sur la simulation et la reconstruction des photons convertis et non-convertis mais aussi sur le signal de physique $H\to\gamma\gamma$.

<p>Bio-inorganic structures have been found to exhibit impressive optical and mechanical properties, such as control of light and/or high fracture strength. Certain species of diatoms (single-celled algae) form siliceous microshells (frustules) with organized structures that affect the transmission of light or fracture strengths. It has been found that <i>Coscinodiscus wailesii</i> diatoms have frustules with a quasi-regular hexagonal pattern of pores, which act as micro-lenses. In terms of mechanical strength, <i>Fragilariopsis kerguelensis</i> diatom SiO₂ frustules have been observed to exhibit impressive compressive and tensile fracture stress values. In this study, shape-preserving chemical conversion (using gas/solid reactions) is used to transform biogenic structures (diatom frustules) into high IR refractive index or ultrahigh specific strength materials. High-fidelity MgO/Si, Mg₂Si, Ca₂Si, MgO/Ti, and Ti replicas are successfully synthesized and characterized by SEM, EDX, XRD, and TEM. Focal point imaging experiments are used to show that focusing behavior of MgO/Si and Mg₂Si replicas can be enhanced in the IR range upon conversion into higher index replicas. Mechanical properties of SiO₂ frustules, MgO/Ti replicas, and Ti replicas have been measured by using in-situ and ex-situ indentation, which revealed that the mechanical properties can be enhanced by the shape-preserved chemical conversion of Bio-inorganic structures.</p><p><br></p>

The aim of the thesis is to revive the former textile factory complex, which is located on a unique place - on the island between the river Svitava and the race. The main idea is to make the area accessible and to use its potential, focusing primarily on the link of history, identity of the place, quality public space and the functional content of the whole area. The concept of the whole work is the planning in time and the gradual phase of integrating brownfields back into the lives of not only local Brno citizens. The island in Obřany could thus become the heart of this city district, a meeting place with a rich cultural life, a space for relaxation, activities and leisure activities close to nature in a charming environment with a touch of Brno's industrial history.

This study investigates the effects of the digital marketing channels Search engine optimization (SEO) and SEM, focusing on Google Ads, in the context of the consumer decision funnel in the Swedish market. This was done through a single-case study with a medium-sized digital marketing bureau in Sweden. Our research was summarized in a conceptual framework that aims to create a foundational understanding of best practices and strategies for companies to establish a robust and profitable online presence. The research shows that SEO and SEM has different main focuses within the digital marketing landscape where SEO has a more holistic approach and covers areas further up in the consumer funnel, and SEM operated more targeted with a high focus on measurable conversions. However, our research also finds how the respective channels both have the capacity to be used in all parts of the funnel. Concepts such as budget, strategy, timeline, and consumer behavior are key concepts within our research. The research highlights the importance of tailoring a digital marketing strategy to a company’s specific goals and circumstances. This research takes such aspects into consideration, and strategies depending on budget constraints and company size are explored separately. This paper thus provides marketers with a foundational understanding of how to approach digital marketing, and how to best tailor a digital marketing strategy to align with company goals. Effectively combining SEO and SEM creates a great opportunity for companies to establish a good online presence, which in today's society serves as a very effective media to reach out to consumers.

Thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Agriculture (Agricultural Economics) at Stellenbosch University / Thesis (MScAgric (Agricultural Economics))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: The main objective of the research is to understand the concept of cooperative conversions and compare the performance of converted cooperatives to those that never converted using financial accounting analysis and organisational dynamism. Even though the differences were relatively small, companies had the strongest relative financial performance than cooperatives. Companies had the strongest performances in asset and revenue growth. Average revenue growth for companies from 2004 to 2007 was 29% as compared to 15% by cooperatives and asset growth was 25% for companies compared to 12.5% by cooperatives. Results further indicate that for the past two years, cooperatives seem to be reporting decreasing performance in most of the financial ratios analysed. Thus, based on results from the financial analysis, operating as a company or converting from a cooperative to a company could result in slight increases in financial performance. Rapid change presents various challenges and opportunities for businesses in today‘s dynamic environment. As a result, business dynamism is becoming an increasingly important aspect and factor in determining success. Based on a dynamism score card, the study shows that companies are by far much more dynamic than cooperatives, with a score of 83.75 compared to 62.33 out of 100 respectively. However, cooperatives compare relatively well to companies in as far as organisational strategy, management, organisational structure and culture. Their limitations come from their property rights framework which is by far less dynamic than that of companies owing to the limitations and constraints of the Cooperatives Act (Act 14 of 2005). The main shortcomings of cooperative property rights were that of not allowing external investors into the cooperative and the one member one vote principle for primary cooperatives or the 15% cap for secondary cooperatives. / AFRIKAANSE OPSOMMING: Die vernaamste doelwit van hierdie navorsing was om die konsep van koöperatiewe omsettings te verstaan en die prestasie van omsette koöperasies te vergelyk met dié wat nog nooit deur middel van finansiële rekeningkundige analise en organisatoriese dinamisme omgesit is nie. Hoewel die verskille relatief klein was, het maatskappye die sterkste relatiewe finansiële prestasie gehad in vergelyking met koöperasies. Maatskappye het ook die sterkste prestasie in bate- en inkomstegroei getoon. Gemiddelde inkomstegroei vir maatskappye vanaf 2004 tot 2007 was 29%, in vergelyking met 15% vir koöperasies, terwyl bategroei vir maatskappye 25% was in vergelyking met 12.5% vir koöperasies. Die resultate toon verder dat koöperasies oor die afgelope twee jaar verminderde prestasie blyk te rapporteer in die meerderheid van die finansiële verhoudings wat geanaliseer is. Dus, op grond van die resultate van die finansiële analise, sal funksionering as ‘n maatskappy of omsetting van ‘n koöperasie na ‘n maatskappy kan lei tot ‘n effense verhoging in finansiële prestasie. Snelle verandering bied verskeie uitdagings en geleenthede vir maatskappye in die huidige dinamiese omgewing. Gevolglik is sakedinamisme besig om ‘n toenemend belangrike aspek en faktor in die bepaling van sukses te word. Op die basis van ‘n dinamisme-telkaart het hierdie studie getoon dat maatskappye baie meer dinamies is as koöperasies, met ‗n telling van 83.75 in vergelyking met 62.33 uit 100 onderskeidelik. Koöperasies vergelyk egter relatief goed met maatskappye in soverre dit organisatoriese strategie, bestuur, organisatoriese struktuur en kultuur behels. Hulle beperkings kom van hulle eiendomsregraamwerk, wat baie minder dinamies is as dié van maatskappye op grond van die beperkings van die Wet op Koöperasies (Wet 14 van 2005). Die vernaamste tekorte van koöperatiewe eiendomsregte is dat hulle nie eksterne beleggers in die koöperasie toelaat nie en die beginsel van een lid, een stem vir primêre koöperasies of die 15% perk op sekondêre koöperasies.

Resumo:Aplicação da Teoria dos Registros de Representação Semiótica no ensino-aprendizagem da Matemática. O objetivo deste trabalho foi verificar se, com a aplicação da Teoria dos Registros de Representação Semiótica, seria possível melhorar o desempenho escolar em Matemática, mais precisamente, na resolução de problemas envolvendo operações com números naturais, junto aos alunos do sexto ano A do Ensino Fundamental do Colégio Universitário - COLUN, da Universidade Federal do Maranhão, Campus São Luís do Maranhão. A tarefa foi iniciada com a aplicação de um instrumento de avaliação denominado Lista de Exercícios, composta de dez problemas, com o objetivo de diagnosticar o nível de desempenho dos alunos. A partir da análise dos dados desse instrumento, foi elaborado um plano de estudos baseado nos conteúdos do livro de Matemática adotado pelo Colégio. Durante a pesquisa, foram feitas várias reuniões com a professora da turma, para verificar se estava havendo melhoria de desempenho dos alunos e, assim, poder ajustar a forma como os conteúdos deveriam ser desenvolvidos em sala de aula, à luz da aplicação da Teoria das Representações. No acompanhamento diário na sala de aula, também foram aplicados outros instrumentos de avaliação, tais como exercícios individuas e em grupo, para comprovar se estava havendo melhoria de desempenho escolar. A aplicação das operações de tratamento nos registros de representação e na conversão semiótica, nos instrumentos avaliativos e nas atividades realizadas em sala de aula, foi feita de forma aleatória, com o objetivo de se garantir a imparcialidade na análise dos dados. Como resultado final da pesquisa, verificou-se que, aproximadamente, 60% dos alunos tiveram bom rendimento (Bom de 61% a 80%) e 37% rendimento regular (Regular de 41% a 60%). Verificou-se, também, que aproximadamente 3% dos alunos não apresentaram... / Abstract:Semiology Presentation Register, applying theory to Mathematics teaching-learning process. This paper aimed to check whether there was a better student performance after Semiology Presentation Register being applied to Mathematics, that is, with regards to solving problems, natural numbers resolutions for the 6th grade fundamental school children at COLUN - Colégio Universitário (UFMA College School). The first task consisted of a list of exercises based on Semiology Presentation Register with ten problems aiming to measure students performance level. From the analysis of the data collected, a study plan was elaborated based on the mathematics book contents adopted by the school. During the research, several meetings were held with the students teacher to detect if there was any improvement on students performance, and thus adjust the way contents would be developed in the classroom on Presentation Register Theory applied to. In observing the daily classroom, several types of evaluations were made, such as single and groups exercises, in order to secure improvement and school performance. The applying of study, approach and semiology conversions, related to evaluation and classroom activities, were made at random in order to guarantee analysis' data impartiality. As the research result it was found out that nearly 60% of students had suitable improvement (good: 61% - 80%) and 37% had fair improvement (fair: 41% - 60%). It was also found out that about 3% of students did not show any problem solution whatsoever. Those results show that it was possible to improve school performance on Mathematics for the researched students. / Orientador: Raul Aragão Martins / Banca: José Carlos Miguel / Banca: Paulo Sérgio Teixeira Prado / Banca: Adriano Rodrigues Ruiz / Banca: Nelson Antonio Pirola / Doutor

Thesis (MA (Geography and Environmental Studies))--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: Land for agricultural development gets scarcer as more and more agricultural land is being transformed by non-agricultural uses. The increased agricultural land use change in the Western Cape Province results in transformation, fragmentation and loss of productive agricultural land. With the A2 planning area of the Department of Environmental Affairs and Development Planning (DEADP), in the Boland region of the Western Cape, as its study area, this study investigates the role of legislative control measures on changes of land use from agriculture to a different form of development, by analysing the Environmental Impact Assessment (EIA) applications for the change of agricultural land use and agriculture applications for the conversion of undeveloped land for the period 1 January 1998 to 3 July 2006. The study examines the role that the relevant legislation plays in agricultural land use control; considers the nature, extent and reasons for agricultural land use change in the study area (under the Environment Conservation Act (Act 73 of 1989) (ECA)); determines the impacts associated with the transformation of agricultural land use in the study area by assessing transformation of undeveloped land applications (captured under the Conservation of Agricultural Resources Act (Act 43 of 1983) (CARA)); and measures the amount of agricultural land potentially lost to development through EIA change of land use applications (according to the DEADP database) opposed to the amount of agricultural land potentially gained through conversion of undeveloped land (according to the DoA database). Two databases were created, based on variables obtained from EIA change of agricultural land use applications authorised by DEADP [DEADP’s database] and conversion of undeveloped land for agricultural use, authorised by the Department of Agriculture (DoA)[DoA’s database]. The variables used to create DEADP’s database are the applicant, property owner, type of property, development function, year of authorisation, municipality, town, size of property, permanent and temporary jobs created, percentage of property developed, footprint of development, existing land use and unique source. The variables used to create DoA’s database are the year of authorisation, new and existing land use, year of authorisation, municipal area, property owner, percentage of property converted and footprint of development. The variables in the two databases are analysed using cross tabulations, with the variables measured against each other using pivot tables. The final tables are investigated through interpretation of the results and making recommendations for better management and planning in the future, based on relevant literature. The main findings are that DEADP gave authorisation for 416 agricultural land use change developments between 1 January 1998 and 3 July 2006, resulting in 2855 hectares of agricultural land potentially being developed. It was also found that DoA gave approval for 118 undeveloped land conversion applications, converting a total of 2589 hectares for agricultural purposes. The findings also revealed that 1707ha of this undeveloped land were covered with indigenous vegetation, while only 299ha were covered with alien vegetation. The challenge is to use valuable agricultural land optimally and sustainably for agricultural purposes. Non-agricultural developments should be kept within the urban edge and away from valuable agricultural land. If such development must take place on agricultural land, it must be done on the poorest soils and should not jeopardise agricultural activities. Keywords: land use change, undeveloped land, applicant, property owner, type of property, development function, year of authorisation, municipality, town, size of property, permanent jobs, temporary jobs, percentage of property developed, footprint of development, existing land use, new land use and unique source. / AFRIKAANSE OPSOMMING: Grond vir landbou ontwikkeling word al hoe skaarser namate meer en meer landbougrond omskep word vir ander grondgebruike. Die gevolg is dat meer landbougrond in die Wes-Kaap omskep word vir ander ontwikkelingsdoeleindes, wat lei tot transformasie, fragmentering en verlies van produktiewe landbougrond. Met die A2 beplanningsgebied van die Departement van Omgewingsake en Ontwikkelingsbeplanning (DOeOB), wat geleë is in die Boland streek van die Wes-Kaap, as studiegebied, ondersoek hierdie studie die rol van wetgewende beheermatreëls op grondgebruiksverandering vir die periode 1 Januarie 1998 tot 3 Julie 2006, deur Omgewingsimpakbepalings (OIB) aansoeke wat ‘n verandering van landbougrondgebruik insluit, asook landbou aansoeke wat die omskepping van onontwikkelde grond insluit, te ontleed. Die studie ondersoek die rol wat relevante wetgewing in landbougrondgebruikskontrole speel; analiseer die aard, omvang en redes vir landbougrondgebruiksverandering in die studiegebied soos voor aansoek gedoen in terme van die Wet op Omgewingsbewaring (Wet 73 van 1989); die impakte wat geassosieer word met transformasie van landbougrond deur verandering van landbougrondgebruik soos voor aansoek gedoen in terme van die Wet op Bewaring van Landbouhulpbronne (Wet 43 van 1983); en vergelyk die hoeveelheid landbougrond wat potensieel omskep is vir ontwikkeling deur middel van OIB verandering van grondgebruik aansoeke (volgens DOeOB databasis) teenoor die hoeveelheid nuwe landbou grond wat potensieel geskep is deur onontwikkelde grond te omskep vir landbou (volgens DvL databasis). Twee databasisse is geskep, gebaseer op veranderlikes wat verkry is uit OIB-aansoeke wat ‘n verandering van landbougrondgebruik ingesluit het en deur DOeOB goedgekeur is [DOeOB databasis] en aansoeke wat ‘n verandering van onontwikkelde grond vir landboudoeleindes insluit, goedgekeur deur die Departement van Landbou (DvL) [DvL databasis]. Die veranderlikes in die DOeOB databasis te skep sluit die volgende in: aansoeker, eienaar, tipe eiendom, tipe ontwikkeling, jaar van goedkeuring, munisipale area, dorp, groote van eiendom, permanente en tydelike werksgeleenthede geskep, proporsie van grond ontwikkel, voetspoor van ontwikkeling, bestaande grondgebruik, nuwe grondgebruik en unieke bron. Die veranderlikes in die DvL databas is: jaar van goedkeuring, nuwe en bestaande grondgebruik, munisipale area, dorp, grondeienaar, proporsie van grond ontwikkel en voetspoor van ontwikkeling. Die veranderlikes in die twee databasisse is ontleed deur kruistabelle. Die finale tabelle word geanaliseer deur die resultate te interpreteer en voorstelle te maak vir beter bestuur en beplanning in die toekoms, gebaseerd op relevante literatuur. Die hoof resultate van die studie toon dat DOeOB goedkeuring gegee het vir 416 landbougrondgebruiksveranderingontwikkelings tussen 1 Januarie 1998 en 3 Julie 2006, wat moontlik veroorsaak het dat 2855 hektaar landbougrond ontwikkel is. Die resultate dui ook dat DvL goedkeuring uitgereik het vir 118 ontwikkeling van onontwikkelde grond aansoeke, wat ’n totaal van 2589 hektaar grond potensieel omskep het vir landbou doeleindes. Die bevindinge bevestig ook dat 1707 hektaar van die onontwikkelde grond bedek was met inheemse plantegroei, terwyl slegs 299 hekaar bedek was met uitheemse plantegroei. Die uitdaging vir die toekoms is om vrugbare landbougrond optimaal en volhoubaar te gebruik vir landbou. Nie-landbou ontwikkelings moet binne die stedelike grens geskied, weg van vrugbare landbougrond. Indien ontwikkeling op landbougrond plaasvind, moet dit op lae-potensiaal landbou grond geskied en geensins landbou aktiwiteite benadeel nie. Kernwoorde: grondgebruiksverandering, onontwikkelde grond, aansoeker, eiendoms eienaar, tipe eiendom, tipe ontwikkeling, jaar van goedkeuring, munisipale area, dorp, groote van eiendom, permanente werksgeleenthede, tydeike werksgeleenthede geskep, persentasie van grond ontwikkel, voetspoor van ontwikkeling, bestaande grondgebruik, nuwe grond gebruik en unieke bron.

In this thesis, we provide an adequate lexicographic representation of lexical-semantic conversion. Under the term lexical-semantic conversion, the relation between semantically similar syntactic structures which are based on separate lexical units of the same verb lexeme is understood. These relations are associated with various changes in valency structure of verbs - they may involve a number of valency complementations, their type, obligatoriness as well as morphemic forms. These changes arise from differences in the mapping of situational participants onto valency complementations. On the basis of semantic and syntactic analysis of two types of Czech lexical- semantic conversions, the locative conversion and the conversion Bearer of action-Location, we propose to represent lexical units creating syntactic variants in the relation of lexical semantic conversion by separate valency frames stored in the data component of the lexicon. The special attribute -conv whose value is a type of lexical-semantic conversion is assigned to relevant valency frames. Then the rule component of the lexicon consists of general rules determining changes in the correspondence between situational participants and valency complementations. This proposal is primarily designed for the valency lexicon of Czech verbs, VALLEX....

The conversion from one to the other is the essence of knowledge creation. Following this principle, the organizational management should create conditions for the exchange of experiences among people for the conversion and consequent sharing of knowledge to flow dynamically in the organizational structure. Technology is a means of access to facilitate dissemination of information and organizational culture elements should contribute to encouraging the creation of new ideas. Considering these arguments, the project will discuss the relationship between tacit and explicit knowledge in four types of conversion, socialization, externalization, combination and internalization. / O presente projeto desenvolve a ideia de que a gestão do conhecimento será eficiente se contemplar o conhecimento em suas duas principais modalidades: tácito, presente na mente das pessoas, e explícito, presente nos registros da organização, nos manuais e nos procedimentos. A conversão do primeiro para o segundo é a essência da criação do conhecimento. Seguindo esse princípio, a gestão organizacional deverá criar condições para trocas de experiências entre as pessoas, para que a conversão e consequente compartilhamento do conhecimento fluam de forma dinâmica na estrutura organizacional. Por um lado, a tecnologia é um meio de acesso para facilitar a disseminação da informação, por outro, a cultura organizacional deverá contribuir com elementos incentivadores à criação de novas ideias. Considerando esses preceitos, o projeto discutirá o relacionamento entre os conhecimentos tácito e explícito em quatro tipos de conversão: socialização, externalização, combinação e internalização.
