This study is about how Athena is portrayed in two of the surviving works of antiquity, the Iliad and the Hymn to Athena by Callimachus. The study further shows in comparison of the two works, how Athena can be described based on her emotions, attributes, actions and character traits. In relation to the Iliad, Athena comes to express emotions such as frustration, dissatisfaction, anger, hatred, happiness, joy and as loving. Furthermore, the analysis of the Iliad has been able to identify actions and character traits such as cunning, persuasion, incitement, courage, eager and quickness. Athena has also been able to be attributed characteristics in relation to her as a goddess of war and her father Zeus within the analysis. The characteristics that emerged during the analysis are the goddess as terrifying, angry, with destructive powers, that she never tires, terrible deity and based on her epithet Tritogeneia.   Through analysis of the Hymn to Athena by Callimachus, the goddess can be attributed to emotions such as pity and love. Unlike the Iliad, emotions of a negative nature such as frustration, dissatisfaction and anger do not appear in the hymn. Furthermore, other actions and character traits can also be attributed to Athena in the hymn, such as female beauty and personal hygiene. The majority of epithets and designations can be attributed to the goddess within the hymn, which, unlike the Iliad, is more numerous in number. The epithets and designations that are claimed are polisgoddess, queen, lady and Thebes. Like other identifications attributed to Athena within the hymn, epithets and designations can be related to context. That in the sense that worshipers want to see Athena appear in their company, which is most likely to happen if they address the goddess with respectful words.

Arbetet bygger på förbättring av befintlig arkitektur för en tjänst som beräknar koldioxidutsläpp för molntjänster. Nuvarande arkitektur bygger på att samla ihop och klumpa stora mängder data i form av användarrapporter. Därefter körs frågor mot det data för att få ut relevant information. Detta kan ta väldigt lång tid. För att försöka påskynda denna process görs en undersökning om man kan minska tiden som går åt att köra frågor mot data om datamängden blir mindre. Detta uppnås genom att filtrera bort oönskad data ur mängden innan man kör frågor mot det. Vidare undersöks om den nya arkitekturen kan möjliggöra för enklare implementation av nya funktioner till tjänsten. Metoden för undersökningen var att bygga en alternativ arkitektur med hjälp av AWS och dess tjänster. Resultaten visar på att även om mängden data som skannas är nästan oförändrat så minskas körtiden avsevärt när den totala storleken på datamängden minskar. Vidare bidrar den nya arkitekturen till enklare implementation av nya tjänster än tidigare. / The current architecture the stakeholders are using consists of collecting large amounts of data. After the data is collected it is queried for relevant information. This query process can take a long time. This report looks at if it is possible to reduce this time by reducing the data size. This is done by filtering the data before doing queries towards it. Furthermore this report will investigate if the new architecture can make it easier to implement new functionality. To investigate these questions a new architecture will be built using AWS. The results show that even though scanning nearly the same amount of data, with the total data size reduced one can drastically reduce the query times. Furthermore this new architecture makes it easier to implement new functionality.

The SCT is a silicon strip detector forming a part of the tracking system of the ATLAS experiment at the LHC. The tracking performance of SCT is influenced by several fundamental effects: multiple scattering, Lorentz drift, energy loss variation, noise occupancy, and δ-ray production. In this thesis, the task requested by the SCT detector group has been performed. Clusters containing a δ-ray, which are assigned to a track were studied on data samples, specially prepared for this purpose. A correction to the affected cluster positions was successfully developed. The correction to δ-rays has been implemented into the ATHENA reconstruction framework and its performance was evaluated. A meaningful usage of correction for the detector alignment has been proposed. The ongoing detailed verification of the performance within the event reconstruction is partially beyond the scope of the thesis work.

Orientador: Edberto Ferneda / Banca: Silvana Aparecida Borsetti Gregório Vidotti / Banca: Guilherme Ataíde Dias / Resumo: A pesquisa realiza um estudo acerca de um catálogo específico, o Athena, considerado um sistema de recuperação de informação estruturado e organizado. Nesse ambiente se tem como objetivo avaliar um conjunto de diretrizes de usabilidade e aplicá-las em sistemas de recuperação de informação na Web, levando em consideração aspectos relativos não só à usabilidade de sua interface, mas também à sua eficiência no processo de recuperação. O estudo se caracteriza como exploratório e descritivo-analítico. Para tanto, procurou-se inicialmente revisar a literatura nacional e internacional sobre recuperação de informação e usabilidade, em várias fontes informacionais, impressas e eletrônicas, como embasamento teórico do trabalho. Em segunda etapa, foi realizada uma análise heurística, e por último foram realizados testes de usabilidade com usuários em que se aplicaram dois procedimentos: um questionário semi-estruturado e um instrumento de observação. Após as análises quantitativa e qualitativa dos dados, o teste com os usuários possibilitou verificar o modo como eles interagem com a interface do Catálogo Athena e as formas de busca que costumam realizar em outras ferramentas disponíveis na Web. Também foi possível validar alguns apontamentos feitos na análise heurística, pois a maioria dos participantes da pesquisa revelou não ter qualquer experiência na utilização do Catálogo Athena. Verifica-se, nesta pesquisa, a importância de se aplicar os testes com usuários em ambientes de recuperação de informação, considerando-os como parte fundamental no desenvolvimento de qualquer sistema. / Abstract: The research conducts a study about a specific catalog, the Athena, considered a system of retrieval of information structured and organized. In this environment you have to evaluate a set of guidelines for usability and apply them in systems for retrieval of information on the Web, taking into account aspects relating not only to the usability of its interface, but also its efficiency in the recovery process. The study is characterized as exploratory and descriptive and analytical. Thus, it was initially to review the national and international literature on recovery of information and usability in various informational sources, printed and electronic, as the theoretical work. In the second stage, was a heuristic analysis, and finally usability tests were carried out with users that were applied in two procedures: a semi-structured questionnaire and an instrument of observation. After the analysis of quantitative and qualitative data, the test allows users to determine how they interact with the interface of the Athena Catalog and the forms of search that usually take place in other tools available on the Web was also possible to validate some notes made in heuristic analysis, because the majority of the research has shown to have no experience in the use of Athena Catalog. This research shows the importance of applying the tests with users in environments of retrieval of information, considering them a vital part in the development of any system. / Mestre

Buildings generate millions of tons of greenhouse gases, toxic air emissions, water pollutants and solid wastes that contribute to negative environmental impacts. Life Cycle Assessment (LCA) is a methodology for assessing the environmental performance of products over their life time. However, many building products are discarded much before the end of their service life, especially as a result of refurbishment and renovation projects. The need for such projects is increasing because most buildings are not designed to accommodate changes in their functions and needs of their occupants. This is particular to commercial buildings, especially hospitality facilities, which are unique with regard to operational schemes and the type of services offered that are highly resource-intensive. In this investigation, statistical data related to refurbishment and renovation projects in Turkey were analysed to determine the percentage of refurbishment projects for hotels. Bills of quantities for refurbishment projects of three five-star hotels in Ankara were obtained and evaluated with regard to the volume and type of material discarded as a result of the renovation works. ATHENA, an LCA software, was used to evaluate these projects according to the six environmental impact indicators: primary energy consumption, solid waste, air pollution index, water pollution index, global warming potential and weighted resource use. A system was formulated for evaluating materials according to each indicator by calculating their &ldquo / eco-scores&rdquo / the total score is considered to be the yard-stick for comparing environmental appropriateness of these materials. Finally, recommendations on the choice of materials were made, with an aim to reducing material waste and harmful emissions.

Yes / The analysis of potentially large volumes of crowd-sourced and social media data is central to meeting the requirements of the ATHENA project. Here, we discuss the various stages of the pipeline process we have developed, including acquisition of the data, analysis, aggregation, filtering, and structuring. We highlight the challenges involved when working with unstructured, noisy data from sources such as Twitter, and describe the crisis taxonomies that have been developed to support the tasks and enable concept extraction. State-of-the-art techniques such as formal concept analysis and machine learning are used to create a range of capabilities including concept drill down, sentiment analysis, credibility assessment, and assignment of priority. We ground many of these techniques using results obtained from a set of tweets which emerged from the Colorado wildfires of 2012 in order to demonstrate the applicability of our work to real crisis scenarios.

Un réseau de seize détecteurs ATLAS-MPX a été mis en opération dans le détecteur ATLAS au LHC du CERN. Les détecteurs ATLAS-MPX sont sensibles au champ mixte de radiation de photons et d’électrons dans la caverne d’ATLAS et sont recouverts de convertisseurs de fluorure de lithium et de polyéthylène pour augmenter l’efficacité de détection des neutrons thermiques et des neutrons rapides respectivement. Les collisions à haute énergie sont dominées par des interactions partoniques avec petit moment transverse pT , associés à des événements de “minimum bias”. Dans notre cas la collision proton-proton se produit avec une énergie de 7 TeV dans le centre de masse avec une luminosité de 10³⁴cm⁻²s⁻¹ telle que fixée dans les simulations. On utilise la simulation des événements de "minimum bias" générés par PYTHIA en utilisant le cadre Athena qui fait une simulation GEANT4 complète du détecteur ATLAS pour mesurer le nombre de photons, d’électrons, des muons qui peuvent atteindre les détecteurs ATLASMPX dont les positions de chaque détecteur sont incluses dans les algorithmes d’Athena. Nous mesurons les flux de neutrons thermiques et rapides, générés par GCALOR, dans les régions de fluorure de lithium et de polyéthylène respectivement. Les résultats des événements de “minimum bias” et les flux de neutrons thermiques et rapides obtenus des simulations sont comparés aux mesures réelles des détecteurs ATLAS-MPX. / A network of sixteen ATLAS-MPX detectors has been put in operation in the ATLAS detector at CERN-LHC. ATLAS-MPX detectors are sensitive to a mixed radiation field of photons and electrons in the ATLAS cavern and are covered with lithium fluoride and polyethylene converters in order to increase the detection sensitivity of thermal neutrons and fast neutrons respectively. High energy collisions are dominated by partonic interactions with small transverse moment pT , associated with "minimum bias" events. In our case, the proton-proton collision occurs with an center-of-mass energy of 7 TeV with a fixed luminosity of 10³⁴cm⁻²s⁻¹ in the simulations. We use "minimum bias" events simulation generated by PYTHIA using the framework Athena. Athena’s framework makes a full GEANT4 simulation of the ATLAS detector. We include the positions of each detector in the Athena algorithms for measuring the number of photons, electrons and muons that can reach the detectors ATLAS-MPX. We measure the fluxes of thermal and fast neutrons generated by GCALOR in lithium fluoride and polyethylene regions respectively. The "minimum bias" events results and the flow of thermal and fast neutrons obtained by simulations are compared with real measurements of the ATLAS-MPX detectors.
