<p>Virtualisering är en abstraktion av underliggande fysisk hårdvara som omvandlas till en förutbestämd struktur av hårdvara via mjukvara. En virtuell maskin kan då vara frånkopplad från hårdvaran. Virtualisering tillåter hårdvara att delas upp som flera separata virtuella hårdvaror vilket kan ske transparent för operativsystem i virtuella maskiner. Virtualisering ökade under 90-talet och det utvecklades två virtualiseringsteknologier: (i) den fullständiga systemvirtualisering och (ii) parallell systemvirtualisering. Fullständig systemvirtualisering erbjuder abstraktion som utgör en frånkoppling från hårdvara. Operativsystem som använder en virtuell maskin känner då inte till att virtualisering skett med resultatet att alla operativsystem kan användas. Parallell systemvirtualisering använder en delvis abstraktion då operativsystem modifieras för att virtuell maskin skall vara medveten om att virtualisering utförts för att möjliggöra för prestandaförbättringar. Den problemställningen som ställts försöker utröna vilken av dessa två teknologier som kan leverera bästa prestanda över FTP. Experiment har då utförts och visade att det är inga skillnader mellan teknologierna.</p>

The question of how to measure and classify people´s risk preferences is of substantial importance in the field of Economics. Inspired by the multitude of ways used to elicit risk preferences, we conduct a holistic investigation of the most prevalent method, the multiple price list (MPL) and its derivations. In accordance with previous literature, we find that revealed preferences differ under various and even the same versions of the MPL. Thus, an arbitrary selection of a particular risk assessment method can lead to biased results especially if researchers investigate its connection to other phenomena. In order to resolve this issue, we determine the most stable version of the MPL by using multiple measures of within-method consistency, and the version with the highest forecast accuracy by using behavior in two economically relevant games as benchmarks. A derivation of the well-known method by Holt and Laury (2002), where the highest payoff is varied instead of probabilities, emerges as the best MPL method in both dimensions.

Diversos aparatos tecnológicos são consequência deste importante ramo da Física que também contribui com a Medicina, Matemática, Filosofia, Literatura e Biologia. Logo, é imprescindível que o contato com esta ciência ocorra no contexto do ensino médio. Para inserir o estudante no mundo da mecânica quântica, isto é, na física do infinitamente pequeno, o aluno deve abandonar o pensamento clássico e pensar em termos do comportamento quântico e do indeterminismo no processo de medida, isto é, desenvolver a capacidade de abstração. Sendo este, o objetivo deste trabalho. Para tanto, foi escolhido o experimento da dupla fenda que permite trabalhar com a dualidade onda-partícula do elétron e do fóton. Por meio deste experimento, o aluno pode ser inserido paulatinamente numa trajetória rumo a descrição quântica necessária para o exame dos fenômenos subatômicos. A análise experimental é cuidadosamente realizada com o auxílio de laboratórios virtuais, disponibilizados gratuitamente em sítios eletrônicos, os quais representam um recurso que permite realizar procedimentos experimentais que necessitariam de grande aparato laboratorial. O experimento da dupla fenda é analisado em três etapas, relatadas a seguir: (i) a dupla fenda com partículas clássicas; (ii) a dupla fenda com ondas clássicas e; (iii) a dupla fenda com objetos quânticos como elétrons e fótons. O objetivo é demonstrar o comportamento dual do elétron. Posteriormente, para concluir de forma precisa e justificar o comportamento quântico do elétron é apresentado o princípio da indeterminação de Heisenberg e suas implicações filosóficas. Sendo assim, o objetivo central desta pesquisa é buscar integrar o comportamento quântico, que acontece na escala atômica, principalmente no contexto do ensino médio. Algumas orientações sobre como aplicar este trabalho em outros níveis de ensino aparecem no decorrer do texto e nos apêndices. Apresentando o comportamento dual, onda–partícula, do elétron, a interpretação probabilística e o princípio de incerteza. Acreditamos que o aluno será capaz de compreender um grande número de fenômenos que acontece em escalas que não são do domínio da mecânica clássica quando, em contato com estes temas. Este tema faz parte do conteúdo de física moderna contemporânea que vem sendo abordado em livros textos e vestibulares. Além disso, algumas das novas tecnologias utilizam a física quântica, desde microscópios eletrônicos, nanotecnologia, computação quântica, semicondutores, diodos (incluindo o LED), transistores, computadores, tablets, GPS, satélites, radares, aviões, lasers, scanners de código de barras, sistemas militares de defesa, CD e Blu-Ray players, criptografia, células fotoelétricas, sensores diversos, basicamente, tudo que é eletrônico. Um dos objetivos do trabalho é verificar quais os conhecimentos prévios o corpo discente possui, antes do contato com o conteúdo de física quântica, ou seja, o que faz parte do senso comum sobre este tema. Além disso, pretendemos verificar se o aluno consegue: i) distinguir, no final da aplicação desta pesquisa, que as leis da física em escalas atômicas são diferentes das leis da física clássica, ii) a importância da mecânica quântica na tecnologia e na sociedade. / Quantum mechanics is one of the areas of physics that emerged in mid-1900 and remains in development to the current day. Several technological devices are a result of this important branch of physics that also helps to Medicine, Mathematics, Philosophy, Literature and Biology. Therefore, it is essential that contact with this science occurs at the high school level, what actually occurs in a limited way, when it happens. To place the student in the world of quantum mechanics, that is, the infinitely small of physics, the student must leave the classical thought and think in terms of the quantum behavior and indeterminacy in the measurement process, namely to develop the capacity for abstraction. This is accurately the aim of this work. Thus, the double-slit experiment that lets you work with the wave-particle duality of the electron and the photon was chosen. Through this experiment, students can be gradually inserted on a path toward quantum description necessary for the examination of subatomic phenomena. The experimental analysis is carefully performed with the aid of virtual laboratories, available for free in electronic sites, which represent a resource to perform experimental procedures that would require large laboratory apparatus. The double slit experiment is analyzed in the following three steps, reported: (i) the slit paired with classical particles; (ii) the double slit and with classical waves; (iii) the double slit with quantum objects such as electrons and photons. The goal is to demonstrate the electron dual behavior. Later to complete accurately and justify the electron quantum behavior shows the principle of indeterminacy of Heisenberg and its philosophical implications. Thus, the main objective of this research is to seek to integrate quantum behavior, which takes place at the atomic scale, especially in the high school level. Some guidance on how to apply this work in other levels of education appear throughout the text and in the appendices. Introducing the dual behavior wave-particle, the electron, the probabilistic interpretation and the uncertainty principle. We believe that students will be able to understand a number of phenomena that occurs on scales that are not the classical mechanics of the domain when in contact with these topics. This topic is part of the contemporary modern physics content that is being addressed in texts and entrance exam books. In addition, some of the new technologies using quantum physics, from electronic microscopes, nanotechnology, quantum computing, semiconductors, diodes (including LED), transistors, computers, tablets, GPS, satellites, radar, aircraft, lasers, code scanners bars, military defense systems, CD and Blu-Ray players, encryption, photoelectric cells, various sensors, basically, everything is electronic. One of the goals of the work is to check what prior knowledge the student body has, before contact with quantum physics content, so the part of common sense on this issue. In addition, we intend to verify that the student is able to: i) distinguish, at the end of the application of this research, that the laws of physics at atomic scales are different from the laws of classical physics, ii) the importance of quantum mechanics in technology and society.

Background: The modern day era of the Internet gave birth to the growing phenomenon of Internet memes (IM), a type of online user generated content (UGC) (Gangadharbatla, 2008). Now marketers have begun researching the relationship between UGC and consumer based brand equity (CBBE) (Christodoulides et.al, 2012; Rachna and Khajuria, 2017). The problem discussion presents the issue of the diminishing control of brand equity due to the rise of UGC and lack of research on how to manage its influence (Morrison et al., 2013). Leading to the purpose of this thesis, which is to determine the impact Internet memes have on consumer based brand equity. Literature: The review presents two leading contributors to the field, Aaker’s (1991) framework on the different dimensions of CBBE and Keller’s (1993) definition of the concept. In addition recent studies on UGC and brand equity provided the basis for hypothesis development. Method: This thesis assumed a deductive research approach, developing the hypothesis from current literature in the field. A quantitative study, that utilized an explanatory research approach, because it best suited the experimental design. As for the data collection method, surveys were considered (Saunders et al., 2016), which the authors designed as a self-completion questionnaire and pre-tested (Bryman and Bell, 2015). Convenience sampling was chosen to select participants (Hernon, 2004). Construct and content validity was used along with homogeneity and stability to control reliability and measure the quality of research instruments (Bryman and Bell, 2015). SPSS version 25 was used to conduct all statistical analyses. Results: Four hypotheses were developed, to measure the effect of the independent variable IM on each of the four CBBE dimensions. To summarize, three of the hypothesis (H1, H3 and H4) were rejected as the difference in the means are not significant enough and can be explained by chance. The effect on brand association (H2) was however found to be significant therefore H2 was accepted.

En värdering av möjliga användningsområden för tillgänglig information är första steg i en sådan utveckling. Denna studie undersöker de praktiska effekterna av att använda positionsdata och bilder från smartmobiler i kombination med traditionella berättande rapporter från allmänheten.Studien påvisar att tillförandet av information från smart teknik under vissa förutsättningar förbättrar positioneringsförmågan när den utförs av försvarsmaktens personal.

La pratique artistique de Piotr Kowalski (1927-2004) est singulière. Mathématicien, scientifique puis architecte, Piotr Kowalski s’oriente dès les années soixante vers la sculpture et créé des outils d’art qui matérialisent des lois physiques ou de pensée. Ses « machines à faire des vierges » agissent sur le spectateur comme principe cognitif en proposant d’expérimenter directement une connaissance. La démarche de Piotr Kowalski rompt avec l’idée romantique de l’artiste isolé dans son atelier. Convaincu que la sculpture doit produire avec les moyens contemporains, il travaille dans les usines et les laboratoires où il met au point des procédés innovants. Cette attitude réconcilie l’art, la science et la technique. La carrière de Piotr Kowalski est emblématique de quarante années de création et de bouleversements institutionnels. Exposés dans les établissements les plus prestigieux (la Kunsthalle de Berne, le Musée Guggenheim, le Stedelijk Museem, le Moderna Musset, le Musée national d’Art moderne), Piotr Kowalski participe en parallèle aux grandes transformations du paysage artistique français (Beaubourg, la Cité des sciences et de l’industrie, la Défense, les villes nouvelles). À travers un parcours chronologique thématisé, cette monographie critique tend à rétablir l’importance d’une œuvre trop souvent réduite à la thématique art et science ou pire à de l’art technologique. La thèse présente le premier catalogue raisonné comprenant les projets d’œuvres non réalisées. / Piotr Kowalski’s (1927-2004) artistic approach is a distinctive body of work. Mathematician, scientist and then architect, Piotr Kowalski focuses from the 60s on sculpture and creates “art tools” materializing laws of physics or ways of thinking. His “virgins maker machines” influence the cognitive part of the viewers by directly experimenting a knowledge. Piotr Kowalski’s approach breaks with the romantic idea of the lonely isolated artist in his workshop. Convinced that sculpture must be made with contemporary means, he works in factories and laboratories, where he implements innovative processes.This attitude enable to bring together art, science and technical knowledge. Piotr Kowalski’s career is the symbol of fourty years of creation and institutional changes. Exhibited in the most prestigious institutions (Kunsthalle in Bern, Guggenheim Museum, Stedelijk Museem, Moderna Musset, Musée National d’Art Moderne), Piotr Kowalski also takes part in the great changes of the French art landscape (Beaubourg, la Cité des sciences et de l’industrie, la Défense, les villes nouvelles). Through a themed timeline experience, this critical monograph tends to restore the importance of his work, often reduced to themed art and sciences, or even worth to technological art. The thesis presents the first catalogue raisonné including his non finalized work projects.
