Water balance and nitrate leaching from arable land in a changed climate : a model study
This thesis aims to present the essential background on how to perform climate changeimpact assessments, and to present the results from a climate impact assessment on waterbalance and nitrate leaching for an arable Swedish soil. The soil is a sandy soil in southwesternSweden, grown with spring cereals. This study is meant to be a benchmark example,and cannot be seen as a regional or national assessment for Sweden, rather as an approachto present and analyze the most important parts of these kinds of assessments.A dynamical simulation model (COUP, Jansson and Karlberg, 2004) was used for thisstudy. The model was parameterized and calibrated against data from an experimental site,located in Mellby in Hallands county, south western Sweden. Measurements were carriedout between 1st of April 1988 and 1st of April 1991.
Speltestning ? Med Fuzzy Logic
Vid design av ett dataspel försöker speldesignern ofta skapa banor och fiender som tvingar spelaren att använda olika strategier för att överleva. För att hitta dessa strategier krävs speltestning. Speltestning är tidskrävande och då också dyrt. Den enklaste metoden för att spara tid är då att använda data hooks i spelet och sedan låta testpersoner spela spelet. Data samlas då in under alla spelsessioner och lagras i loggfiler.Med hjälp av data hooks samlades data in till denna rapport.
Cementstabilisering av Biltemas andra lagerbyggnad i Halmstad
This is a technical report about cement stabilization in general and the stabilizationprocess during the construction of a warehouse in Halmstad, Sweden in particular and iswritten at the section for economy and technology at Halmstad University incollaboration with NCC Anläggning.NCC encountered variations in compression strength in the stabilized material on the firstwarehouse that they constructed for the company Biltema. In our report we used thestabilization process of the second warehouse for the same company as a reference todetermine what could be done to get a more homogeneous result for future projects.We also looked in to what testing method is the most suitable to determine the result ofthe stabilization.After interviews with people involved in the process and visits on the work site we havecome to the conclusion that the most probable cause to the variations in compressionstrength is segregation in the ballast material. This segregation can occur in severaldifferent occasions in the process such as during the production, transportation andhandling on the work site.Other causes for the variation can be improper compaction, overlapping stabilization insome places and different duration of hardening of the samples that are tested.The best way to do in situ test of the stabilized material is to do seismic investigations asthose are non-destructive tests in comparison to taking core samples and you can discoverany cracks or air bubbles in the material..
Regression då data utgörs av urval av ranger
För alpina skidåkare mäter man prestationer i så kallad FIS-ranking. Vi undersöker några metoder för hur man kan analysera data där responsen består av ranger som dessa. Vid situationer då responsdata utgörs av urval av ranger finns ingen självklar analysmetod. Det vi undersöker är skillnaderna vid användandet av olika regressionsanpassningar så som linjär, logistisk och ordinal logistisk regression för att analysera data av denna typ. Vidare används bootstrap för att bilda konfidensintervall.
Intresseavvägningen i personuppgiftslagen - Det kommersiella intresset
Personuppgiftslagen (1998:204) är en lag som syftar till att skyddavåra personuppgifter. Huvudregeln i personuppgiftslagen är attsamtycke krävs från den som personuppgifterna tillhör för att de ska fåbehandlas. Till denna huvudregel finns det dock ett viktigt undantagsom stipulerar att om behandlingen är nödvändig får den utföras utansamtycke, om exempelvis ändamålet uppfyller ett berättigat intressehos den som ämnar behandla uppgiften som väger tyngre än denenskildas intresse av skydd för den personliga integriteten. När ettsådant berättigat intresse ställs mot den personliga integriteten blir enintresseavvägning nödvändig för att avgöra om behandlingen skallvara tillåten eller ej. Det berättigade intresset som upptar dennauppsats är det kommersiella intresset, som exempelvis omfattar ettföretags intresse av att behandla personuppgifter för att via direktmarknadsföring marknadsföra sina produkter.
Inverkan av stora mängder halm som underlag i grisningsboxen på den nyfödda smågrisens temperaturreglering :
The aim of the present study was to evaluate the effects of large amounts of straw
in the farrowing pen on thermal regulation of the newborn piglet in different
weight classes. 20 sows were given 15 kg of straw in the farrowing pen
2 days prior to until 7 days after parturition. A control group of 18 sows
had no straw in the pen. 6 litters from each treatment were observed.
Measurements of piglet body temperature were made at 0h, 2h, 4h, 8h and 24h
after parturition. At ?8h? the body temperature of the piglets in the Straw group
were significantly higher (P=0,0149) than the piglets in the Control group.
Uppskattning av Ytkurvatur och CFD-simuleringar i Mänskliga Bukaortor
By applying a segmentation procedure to two different sets of computed tomography scans, two geometrical models of the abdominal aorta, containing one inlet and two outlets have been constructed. One of these depicts a healthy blood vessel while the other displays one afflicted with a Abdominal Aortic Aneurysm. After inputting these geometries into the computational dynamics software FLUENT, six simulations of laminar, stationary flow of a fluid that was assumed to be Newtonian were performed. The mass flow rate across the model outlet boundaries was varied for the different simulations to produce a basis for a parameter analysis study. The segmentation data was also used as input data to a surface description procedure which produced not only the surface itself, but also the first and second directional derivatives in every one of its defining spatial data points.
"Snipp snap snut, nu tog tiden slut" : En analys av användares medvetenhet kring integritet på mobilapplikationer
This study focuses on the integrity of students at Uppsala University that has used the university?s network, UpUnet. We?ve studied their opinions with the use of questionnaires that cover questions related to privacy and awareness about logging of data traffic.The results showed that more students than our hypothesis suggested were unaware of the surveillance on the network, and the majority of these also had a negative opinion towards logging of data traffic. However, we found that there were several relations between how the students responded on our questionnaire, and we?ve presented these in the analysis chapter towards the end of the essay..

The tool is called PLS (Process log server), and is developed in Visual Studio.NET Framework 2005. PLS works as a client with Beijer Electronics OPC Server. The program is able to read data from PLC (Programmable Logic Controller), trough the OPC Server.
Högre krav men mindre tid : en jämförande studie av lärares upplevelser av fördelningen av arbetstiden
Purpose: The purpose of this study is to find out how much influence underlying factors have in connection to the internationalization of Born Global firms. Methodology: This study has a qualitative approach in which data is obtained mainly through interviews and secondary data which consists previous theories about the internationalization in small and medium sized firms and recent theories that entitle these firms as Born Global. Conclusion: Based on the existing theories and the qualitative data, we have concluded that the underlying factors for the Born Global firm?s internationalization are abilities and opportunities to create insidership in relevant networks. The most crucial underlying factors for Born Global firm?s internationalization are the ability to create processes to break old patterns of thoughts and the ability to ally with right partners. .
Välfärdsstad i förändring-Idéburna organisationers roll i dagens socialpolitik
The Swedish society and welfare model are under constant changes anddevelopment. One of the core areas in this welfare model is the social policy. By analysing the changing role of the organizations in the civil society on a local level with a theoretical typology changes in the roles can be noted. These changes can with a model for ideal types raice questions about bigger changes concerning issues of legitimacy and accountablility. I uses qualitative method including interviews with actors on the local level, earlier reseach in the field and public documents.
Informationsmäklarens roll i gränsöverskridande aktiviteter - En studie kring mervärdet av informationsmäklare
En teknik som på senare år fått allt större uppmärksamhet på grund av dess potentiella nytta är RFID-tekniken som bland annat utlovar kostnadsminskningar och ökad konkurrenskraft. RFID i en logistikkedja genererar stora mängder data som måste lagras, hanteras och användas i realtid. Detta tillsammans med antalet användare av denna data gör att informationsmäklare kan vara nödvändiga. En informationsmäklarens uppgift är att hantera avläsare, filtrera och aggregera den insamlade RFID-data och skicka den, förädlad, till användaren av den data. Då utbudet av forskning kring de mjuka aspekterna av informationsmäklare inom RFID är begränsad är det oklart vilken roll informationsmäklare har vid gränsöverskridande aktiviteter.
Solokvist eller ensamvarg : Socialt samspel hos personer med psykosproblematik
Background: People diagnosed with psychosis are often described as introvert, isolated and with little or no ability to create and maintain social relationships. While every angle of a phenomena is valid and important, we believe that the first-person perspective provides the only direct access to the diagnosed persons? feelings and experiences.Aims: The aim of this study is to explore how a few people diagnosed with psychosis describe their experiences of social interaction.Method: This study is conducted in a Grounded Theory manner. An analysis has been performed on interviews made with five individuals, all diagnosed with a psychosis diagnosis.Results: The main result of this study is that the self-image is a core factor in the individuals experiences of, and initiative to, social interaction. The social interactions are linked to the individuals own relation to their diagnosis in a dynamic process where all components affect each other in the creating of the self-image.Conclusion: This study concludes that people diagnosed with psychosis is no different than other people when it comes to dreaming and longing for functional social relationships, but that they have some difficulties in actually finding them due to both social stigma and a poor self-image..
Svensk delnormering av Lundamaterialet för åldrarna 3:0?5:11 år och undersökning av materialets effektivitet
The purpose of this study was to collect Swedish normative datafor Lundamaterialet for children aged 3:0-4:5 years. Another aim was toexamine the effectiveness of the test; if it elicits adequate responses fordeciding if a child has acquired a specific language structure or not.Normative data was collected for 195 children with typical languagedevelopment. Participants were recruited from pre-schools in themunicipalities of Göteborg, Mölndal, Härryda and Skövde. This studypresents normative data for 79 children constituting the three youngest halfyeargroups. Results show that the children had acquired more than half ofthe investigated phonological and grammatical structures and that the olderchildren had acquired more structures than the younger ones.
Utveckling av ett svensk-engelskt lexikon inom tåg- och transportdomänen
This paper describes the process of building a machine translation lexicon for use in the train and transport domain with the machine translation system MATS. The lexicon will consist of a Swedish part, an English part and links between them and is derived from a Tradostranslation memory which is split into a training(90%) part and a testing(10%) part. The task is carried out mainly by using existing word linking software and recycling previous machine translation lexicons from other domains. In order to do this, a method is developed where focus lies on automation by means of both existing and self developed software, in combination with manual interaction. The domain specific lexicon is then extended with a domain neutral core lexicon and a less domain neutral general lexicon.
