To render outdoor scenes with lots of vegetation in real time is a big challenge. This problem has important applications in the areas of visualization and simulation. Some progress has been made the last years, but a previously unsolved difficulty has been to combine high rendering quality with abundant variation in scenes. I present a method to mathematically generate and render vegetation in real time, with implementation in the scene graph Gizmo3D. The most important quality of the method is its ability to render scenes with many unique specimens with very low aliasing.

Delaktighet är ett multidimensionellt fenomen som gynnas av ett flertal faktorer, främst positiva personegenskaper och underlättande faktorer i miljön. Syftet med studien var att undersöka hur vårdare på en gruppbostad för vuxna personer med lindrig utvecklingsstörning uppfattar samt menar sig skapa förutsättningar för brukarnas delaktighet i fritid, mathållning, städ/tvätt och ekonomi. Studien genomfördes med hjälp av 6 individuella intervjuer med halvstrukturerade frågor. Resultatet visade att vårdarna uppfattar brukarnas delaktighet i sin fritid som stor, då självbestämmandet och engagemanget är stort. I mathållningen har brukarna självbestämmande, men de väljer att inte vara delaktiga.

Tidigare forskning belyser den påfrestande tid nyutexaminerade sjuksköterskor befinner sig i under inträdet till den nya yrkesrollen. Studiens syfte var att genom intervju undersöka nyutexaminerade sjuksköterskors upplevelser av sin första introduktion. Nio sjuksköterskor deltog i studien. Under introduktionen sker ett rollbyte från student till legitimerad sjuksköterska med tillhörande ansvar. Rollbytet skapar stress och osäkerhet vilket leder till ett stort behov av stöd och samtal.

Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.

In these days we can witness a growing number of combined school and public libraries in Sweden. It can be explained as an economy measure or as an attempt to develop the library work. The aim of this thesis is to picture how working in combined libraries affects high school librarians? own apprehensions of their professional identity. The results are based on in-depth interviews made with four high school librarians, working not only towards the students but also the public.

The use of subscription services directed towards customers has become a common phenomenon in a vast number of different industries. We have noticed a clear trend of new businesses emerging solely offering subscriptions, and existing companies altering sales of their products to become parts of subscriptions. But research has not caught up with this trend yet, especially regarding why it occurs and how it affects existing businesses internally. The purpose of this study is to examine the driving forces for change and examine how existing businesses have to change parts of their business models to offer subscription services. The premise of this study has been Vargo & Luschs (2004) Service Dominant Logic with their foundational premises and Business Model Canvas by Osterwalder et.

Syftet med Barnahus är att barn som misstänkts blivit utsatt för våld eller övergrepp ska i en trygg och barnvänlig miljö förmedla sin upplevelse, samt hjälpa barnet genom stöd och insatser att bemästra utsattheten. Studien grundas på kvalitativa intervjuer som metod. Respondenterna som ingår i studien representerar Socialtjänsten, Polismyndigheten, Åklagarmyndigheten, Barnkliniken och Barn- och ungdomspsykiatrin. Resultatet presenterar samverkansparternas upplevelse av samverkans funktion, fördelar och brister, samt hur barnets rättigheter tillämpas i utredningsprocessen. Resultatet påvisar att respondenterna upplever samverkan i Barnahus som en möjlighet till personlig och yrkesmässig utveckling, och att samverkan över yrkesrollerna är en förutsättning för att tillgodose barnets behov av skydd och trygghet.

In todays' society e-commerce is growing at a rapid speed. 4,6 % of all retail sales on the Swedish market are done on the Internet. In the makeup category, which will be the category of focus in this study, 9 % of all the sales were done on the Internet during the last quarter of 2011. As it is today many suppliers do not have enough knowledge about e-commerce and instead of focusing on the development of the channel the focus should instead be on the development of the users of the channel.The purpose of this study is to understand the buying process with respect to the existing theories. The focus will be on the two stages information search and evaluation of alternatives.

The aim of my thesis was to investigate in what grade teachers who work within special education make use any methods to train the working memory of their students to improve learning ability. I also wanted to examine the material used to train working memory and if any results were noticed. My choice of method was qualitative semi-structured interviews that were recorded during the interviews I conducted these in five different school with education for children with intellectual impairment. The result shows that the schools that are aware of recent research on working memory training had methods for training with their students. They could also see a result that shows that working memory can be improved with training.

AbstractThe purpose of this thesis is to examine if performing art is a good medium to convey human rights.To make this examination Riksteatern, The National Touring Theater of Sweden has been used as anexample. To bring more depth to the thesis and to be able to answer whether performing art is agood medium to convey human rights Riksteatern´s work with human rights has been examined andalso what kind of responsibility Riksteatern think they have to communicate human rights. Toanswer the questions the thesis have investigated Riksteaterns policy documents, webpage, differentprojects and performing arts performances. Moreover interviews with five employees at Riksteaternhas also been used to answer the questions. Different theories regarding theater, culture and learninghave been used to highlight what purpose art and culture has and to see what kind of qualitiesperforming arts has when it comes to convey human rights.

I sitt dagliga arbete möter sjuksköterskor svårt sjuka patienter. Ibland kan det bli aktuellt att på en del av dessa patienter ta ett förhandsbeslut om att inte återuppliva dem vid ett eventuellt hjärtstopp, ett så kallat ejHLR-beslut. Syftet med studien var att undersöka sjuksköterskors erfarenhet av ejHLR med fokus på vilken kunskap de har om innebörden av begreppet samt vilken syn sjuksköterskor har på sitt eget, patienters och de anhörigas deltagande i beslutstagandet. Studien som gjordes var en litteraturstudie och omfattade både kvantitativ och kvalitativ forskning där totalt 11 artiklar inkluderades. Resultatet visar på bristande kunskaper hos sjuksköterskor, dels om definitionen av ejHLR men även om riktlinjer för beslut om ejHLR. Det uppvisar också att sjuksköterskor anser att dem själva, patienten och anhöriga borde vara med och fatta ett eventuellt ejHLR-beslut men att rollerna i beslutsfattandet är vaga.

Examensarbetet behandlar delaktighetsbegreppet i fritidshemsverksamheten. Syftet med vår undersökning var att se hur delaktiga eleverna är i fritidsverksamheten och hur pedagogerna arbetar med elevdelaktighet. Alla har rätt till en likvärdig utbildning men hur det kommer till uttryck i verksamheten kan se olika ut beroende på de förutsättningar som finns. Undersökningen belyser pedagogers bristande kompetens att tillgodose elevers behov. Via den empiriska insamlingen framkommer det att pedagogerna som intervjuats är överens om vad begreppet delaktighet innebär.

Glulam is a product that was engineered to make use of timber in a more efficient way. Bychoosing timber of similar quality and discarding natural defects during production, thedevelopment of a stronger cross-section is achieved.Carbon fiber is a relatively new material with a high tension capacity. This feature is used toexamine how the bending capacity of the beams improve by adhering carbon fiber laminateson the lower edge of the beamsThe strength of the material is tested with three experiments: carbon fiber on the bottom of thebeam (a), carbon fiber attached to the lower sides of the beam (b) and carbon fiber in thebeam, covered with a layer of wood (c)The results show that the first case, where the carbon fiber is attached to the bottom of thebeam, gave the best result with an increase in capacity of 59 % compared to the nonreinforcedcontrol. The other two cases also show an improvement in capacity, beam-type 3had a capacity increase of 47% and beam-type 4 increased with 25 %Tests were also made with glulam beams reinforced with fiberglass, but these tests were notanalyzed in depth because the purpose was to compare the capacity to carbon fiber. Thisbeam improved its capacity by 40.3%.The tests show that carbon fiber as a reinforcement material for glulam is a good choice whenthere is a requirement for stronger cross-sections in both new production and renovation ofold buildings.

The aim of this study is to through six interviews, with six experienced, social workers?, in three cities, understand how the child?s position in the Swedish child protective services? enquiries has change, and the factors behind it. The aim is also to compare if the social workers? view of the child?s position in the enquire has change accordingly to Socialstyrelsens intentions of BBIC. The theoretical approaches that was used is the new institutionalism, the Shier?s pathways to participation and the term discretion.

Eftersom anestesi påverkar homeostasen är det alltid förenat med risker. Mätning av anestesidjup, en term som kan delas upp i hypnosgrad och analgesigrad, har diskuterats sedan anestesins födelse. Trots det saknas fortfarande en objektiv mätmetod för detta och de parametrar som används idag tycks inte reflektera inte graden av medvetande direkt. Bispectral Index (BIS) är en mätmetod baserad på en algoritm framtagen genom att studera elektroencefalogram (EEG) hos hundratals människor i vaket tillstånd och under anestesi. Metoden omvandlar EEG-aktivitet i hjärnan till en siffra som speglar hypnosdjupet mellan 0-100, där 100 representerar en helt vaken patient och 0 EEG-tystnad. BIS-värden mellan 40-60 indikerar på människa ett kirurgiskt anestesidjup.
