Konstruktion av upprätningssystem för CICLoPE

Today there is no way of measuring or simulating turbulent flow in high Reynolds numberenvironments. The computational power required to simulate these conditions is not expectedto be available for several decades so instead the CICLoPE project aims at solving thisshortage by the construction of a long carbon fiber wind tunnel in which real measurementscan be made. To do accurate measurements it is of importance that the wind tunnel, 0.9 metersin diameter and 110 meters long, is as straight as possible.This master thesis treat the design and construction of a device which may be used to align thetunnel along a reference laser beam. A design is presented which allows the pipe to be alignedwithin about a quarter of a millimeter along its entire length. Contents span over severalScience fields such as physics, mechanics, control theory and electronics.The result is a theoretically correct design.

The study was done with a qualitative method, where we conducted interviews with six boys who were all born in 1997. The results showed that they knew how to react critically to information on Twitter.

?Det är järnet i blodet som väger? : Elevers uppfattningar om materia en kvalitativ undersökning i årskurs 3

The purpose of this investigation was to find out more about students? spontaneous ideas about properties and transformations of matter. Examples of matter chosen are such which students know about from everyday life and focus is mainly on the questions if students know that all matter has weight and that matter is preserved in transformations.The method used is semi structured qualitative interviews with individual students. Different experiments were carried out together with the students who afterwards were interviewed. However, the students show varying answers and no generalizations can be done.

En studie av ekonomiska sanktioner - Försvarbart utrikespolitiskt verktyg eller irrationell galenskap

Den här uppsatsen mål är att undersöka om ekonomiska sanktioner är ett försvarbart utrikespolitiskt medel. Sanktioners effektivitet utreds genom en kvantitativ studie av sanktioner utfärdade av FN och en kvalitativ studie av fallet Sydafrika. Uppsatsen konstaterar att ekonomiska sanktioner är ineffektiva och kostsamma och går därefter över till att diskutera dem i normativ analys och försöker sedan utreda vilka fördelar som kan identifieras och erbjuder konstruktiv kritik av ekonomiska sanktioner. En positiv faktor som identifieras är den psykologiska påverkan som sanktioner har på en inhemsk motståndrörelse för att visa omvärldens stöd. Slutligen konstateras att smarta sanktioner och vapenembargon kan vara komplimenterande åtgärder, men inte uppfyller sina mål utan hård bevakning..

Allmänna bestämmelser Avtal 90 version 2004; En undersökning av enskilda villkor och skapandet av ett tilläggsavtal

Abstract The IT- business is a fast growing business trade. This expansive line of business continuously demands flexibility both economically and legally. It is, today, of great importance to have knowledge about your own trade especially when it comes to new agreements. Laws and regulations are seldom flexible and adaptable tools, this is due to the fact it takes time to create new laws and, above all, it takes time to create laws with the right effect. This is where standard agreements enter the scene.

Sverigedemokraterna - En retorisk studie

The Sweden democrats are a political party that has had a time of success duringthe last year. However many people believe them to be a racist party, in contrastto how they view themselves and their political message. How is it possible thatthe views of the same party differ to this extent, it seems to be a large ambiguityin their message. Rhetoric is a tool that everybody uses in some way or anotherand can be crucial to how a political party is perceived by people. Can thereforethe use of rhetoric be a factor that has contributed to the different perception of theparty and if so, in which way?With the help of theories such as semiotics, classical rhetoric and antiestablishmentstrategy, different texts, such as motions, and pictures published bythe Sweden democrats can be analyzed to find ways they use rhetoric.In the analysis it was obvious that they used rhetoric, even though therhetorical quality differed between the leading persons in the party and the peoplewho represented the Sweden democrats in the local government.

Utvecklande AI - En studie i hur man skapar ett system för lärande AI

AI är något som blir allt viktigare inom dagens spel och får allt högre krav på att agera mänskligt och intelligent. Detta kandidatarbete undersöker vilken metod som är att föredra för att skapa en AI som kan lära sig av sina tidigare erfarenheter. Några av de metoder som undersöks är trädstrukturer, Artificial Neural Network och GoCap. Genom att skapa en applikation med en av metoderna samt göra en undersökning på hur AI:n i applikationen upplevdes fick vi resultat om denna metod var användbar. Utifrån detta diskuteras det ifall andra metoder hade varit mer effektiva, hur man hade kunnat förbättra AI:n samt hur framtiden för spel-AI skulle kunna se ut..

Nya gränssnitt mellan människa och hav: interaktiva teknologier för ett marint upplevelsecenter.

This thesis project explores technologies that enable people to experience the world through animals' senses in order to spark interest in and awareness about the marine environment and its inhabitants. The project is carried out as part of a planned ocean themed Science center. The purpose is to explore how a greater understanding of the marine environment can be achieved using interactive technologies. The thesis is based on a theoretical framework consisting of academic works on experience, learning in a museum context and sensory perception. Our proposed designs are a series of, primarily, wearable devices that translate sensory experiences and principles from the marine world to humans.

Lost in translation? En empirisk undersökning av användningen av tesaurer vid queryexpansion inom Cross Language Information Retrieval

The purpose of this thesis is to examine the performance of queries that is expanded before translation in comparison with only translation of the queries using a bilingual dictionary, and also to see if the number of terms that was used to expand the queries was of any importance i. e. if many terms from a thesaurus helped or destroyed a query. To answer these questions i used two online thesauri, Rogets thesaurus and Merriam-Webster Online and one printed bilingual dictionary, Norstedts English-Swedish dictionary. Even though the number of examined queries is too small to draw any definite conclusions, the results suggest that expanding using a general thesaurus may have a negative effect on the queries.
