Mikrovågssimulering med realtidsljus : Realtids-ray tracing i CUDA

Detta arbete undersöker möjligheterna med att simulera mikrovågor i ett slutet system. Systemet implementeras med en redan befintlig teknik kallad Ray tracing. Ray tracing är en ljussättningsteknik som går ut på att simulera fotoners rörelse mellan ljuskälla och betraktare i en miljö man önskar ljussätta, och sedan belysa de områden som blir träffade för att på detta vis rendera en bild. Fotoner och mikrovågor har egenskaper som liknar varandra då de båda är elektromagnetism med olika våglängder. Ray tracing är en krävande algoritm då många uträkningar för varje foton måste utföras varje uppdatering.

Mötet med patienten vid klamydiasmittspårning : En kvalitativ studie om barnmorskans upplevelse av mötet

Background: Studies show that unsolved contact tracing of chlamydia increase in Uppsala County. Research shows that the meeting between patient and caregiver, when performing a contact tracing, may be crucial to the outcome of contact tracing. Objective: The aim of the study was to investigate how midwives describe the encounter with the patient during contact tracing in youth clinics in Uppsala County Council. Methods: A qualitative approach with semi- structured interviews was used to collect data. Nine midwives of varying age and work experience from seven different youth clinics in Uppsala County Council were interviewed.

Simulering av exteriört bussljud : Undersökande av en Ray Tracing metod för ljudsimuleringar

En metod för att simulera exteriört bussljud med hjälp utav Ray tracing har testats och utvärderats. En modell av en buss har byggts upp i ett CAD program. Dominerande ljudkällor i bussen samt materialkoefficienter har tagits fram för de material som ingår i bussen. Bussen har sedan förts in i simuleringsprogrammet Odeon, där ett antal simuleringar har utförts. Olika pass-by simulering har utförts och jämförts med mätningar.

Flyktingpolitik och spårberoende : En jämförelse av svensk och finsk flyktingpolitik

The essay aims to compare Swedish and Finnish decisions regarding refugee policies by tracing them back to the critical junctures when the policies were established, in order to explain why there are big differences prevalent today. The questions asked involve the motivations of the refugee policies and how they have changed over time.The theoretical framework employed is based on historical institutionalism and path dependency. By using a most similar system design and process tracing, material in the form of government declarations and government bills are studied and summed up in two analytical models. The results show that there might be a weak path dependency in the case of Finland. However it is more apparent in the case of Sweden, with frequent statements of a generous refugee policy that is characterised by humanity.

Tsunamin - Krishanteringens beslutsprocesser

When the Tsunami occurred on Boxing Day 2004 it caused a major stress upon the governmental agencies in not only the affected areas but also in states that had a large number of citizens in the affected area. The governmental agencies were not prepared for the demands from the citizenry in these countries to deal with rescue and crisis management in areas situated halfway around the globe. This thesis main purpose is to research what the causal mechanisms of Sweden?s and Finland?s crisis management were through the method of process tracing. Taking its theoretical stance in Allison?s & Zelikow?s three models of decision making, the thesis compares the course of events of the first two critical days in Sweden and Finland to establish what mistakes were made during this critical period.

By the Secret Fashion Concil. Project No 1 - jewellery collection

The Secret Fashion Council blends spirituality with fashion, art and design. This jewellery collection shows the connections between parapsychology and quantum physics, based on the study of matter and energy, that everything in the universe is built of vibrations. Many believe psychics have the ability to sense this. By using the skills of a psychic, the Secret Fashion Council invites the wearer to have the jewellery ?read? and evaluated in a most special way, tracing the wearer?s spiritual past, present and future.

Det Otidsenliga : Om tid och tänkande hos Gilles Deleuze

Through the notions of the untimely (l'intempestif) and untimeliness (intempestif) this paper seeks to gain a better understanding of the problematic surrounding and determining the concept of time in Deleuze. By tracing Deleuze's development of the concept of the untimely through Nietzsche and Kant, we are allowed to concretize the concept of time as pertaining to an experience of modernity (modern life), thus enabling us to better determine the place it holds within the philosophy of Deleuze itself - as a constitutive and productive problematic relating directly to the activity of thinking and being philosophically..

Valfrihet eller solidariskt ansvar? : En kvalitativ fallstudie av Socialdemokraternas ståndpunkt i ebo-frågan mellan 1994-2009

The objective of this undergraduate thesis is to study the Swedish Social Democatic Party?s standpoint of the law allowing asylum seekers to choose where to live (ebo) between 1994-2009. The study?s empirical material is being based on official documents from the Swedish Parliament, which is being analyzed by a method called ?process-tracing?. A research question has been formulated to supplement the objective:What arguments has the Swedish Social Democratic Party expressed pro and con the law of ?ebo?? The study?s theoretical framwork is based on two theories which explain incentives behind parties? decision-making, strategic or ideological, on three arenas. As the law was ratified the party took a positive standpoint, but later shifted to become stricly against it.

Förhandling av kärnvapennedrustningsfördrag : En jämförande studie av CTBT och FMCT

AbstractThis essay discusses the negotiation of the Comprehensive Test Ban Treaty (CTBT) and the process that led up to a signed agreement. The CTBT forbids all nuclear weapon test explosions and all other types of nuclear explosions. The purpose of the study was to distinguish the critical steps of the negotiations that resulted in the success of the CTBT. Based on these insights, my intention was to identify relevant events and actors in the process around the Fissile Material Cut-off Treaty (FMCT), which has been on the nuclear disarmament agenda for over a decade. Furthermore, my ambition was that the examination of the CTBT negotiation would give me some clarity in what the next step would be to get the FMCT back on track.

Blodets biopolitik : Heterosexuell hygien och män som har sex med män

Following the wake of the AIDS-catastrophe in the beginning of the eighties, homosexual men or 'men who have sex with men' (MSM) have been barred from donating blood throughout the planet. In this thesis I look into the different discourses at play in the context of creating the legal framework for blood donation in Sweden. Genealogically tracing the emergence of the category of MSM and mapping how the category is brought to use in contemporary negotiations on blood safety, I scrutinize how scientific truth is established within blood transfusion practice. I argue that the rationality of risk group exclusion is contingent on economical grounds, and that the foucauldian concept of biopolitics could productively be used to understand this rationality. In particular, the concept of the 'biopolitics of blood' can be employed in order to understand the reluctance from the involved actors to acknowledge the heteronormative consequences of the legal framework of contemporary blood donation..

Modellering av en komplex ljudkälla med användandet av rumsakustisk modellering baserad på geometrisk rumsakustik

Detta arbete är genomfört i samarbete med ÅF Ingemanssons i Göteborg . Syftet med examensarbetet är att undersöka hur ljudkällor ska modelleras för att dess ljudeffekt och riktningskarakteristik ska överensstämma med dess verkliga motsvarighet. Syftet är att utifrån enkla mätningar i fält kunna modellera upp ljudkällorna i rumsakustisk programvara för att kunna bedöma hur de sprider buller i lokalen. Detta examensarbete utgör en första del i detta arbete och fokuserar på själva källan och tar inte hänsyn till bullerspridningen i lokalen. Allmänna akustiska begrepp som berör rumsakustik och ljudkällors egenskaper undersöks.

Fornstora dagar och framtidens risker : Historiemedvetande och historiebruk kopplat till Sverigedemokraternas principprogram från 2005 och 2011

The subject for this thesis is to analyze the Swedish political the Sweden Democrats (Sverigedemokraterna) through the use of history theories. The purpose is to examine the following two questions:1. what types of history consciousness is present in the source material2. the use of history (historiebruk) shown in the source materialThe source material has consisted two official party publications, Sverigedemokraternas principprogram from 2005 and 2011.The main theoretical frameworks for the analysis has consisted of the typology for use of history as presented by professor Klas-Göran Karlsson together with selected theories connected to history consciousness, not the least the model presented by Bernard Eric Jensen.The result of the analysis shows frequent examples where the use of history and history consciousness is present in the rhetoric used in the source material. By tracing the use back to the theories selected Sverigedemokraterna?s deployment of use of history and history consciousness is interpreted and discussed..

EMU till varje pris? : Spårbundenhet i beslutsfattandet angående EMU

In 2002, the euro as a common currency did replace the national currencies in the EU member-states that did choose to take part in the EMU. It was then viewed as one of the greatest accomplishments ever to be made by the EU. However, during the latest years, the economic situation has deteriorated in several EMU member-states. This affected the whole euro-area and the current situation is referred upon as the euro-crisis. In 2011, at the time of the euro-crisis, the Heads of State or Government of the euro-area did reaffirm their full commitment to strengthen EMU.

På vilka sätt kan stakeholders påverka EU? : En jämförelse av stakeholders påverkan på EU:s GMO policy och på ramdirektivet för vatten

How stakeholders can influence EU in global environmental politics and what consequences and risks this brings are heavily debated. Some scholars argue that civil society are being disenfranchised from the global political arena while others seem to find them having influence in areas where they normally shouldn´t have any influence. In this this paper I will compare the Europan Union policy on GMOs with the process in producing the Water Framework Directive using an analytical framework to study the level of stakeholder influence. Following the framework I will use two types of data namely NGO participation and Goal attainment. The data once summarized will be analyzed by using the methods of process-tracing and counterfactual analysis.My conclusions regarding both cases are that stakeholders, most notably, were able to influence policymaking in EU by using the internal revisions and by networking in smaller partnerships.
