Due to excess precipitation that cause runoff, all soils in Sweden naturally leaches nitrogen.High leaching from arable land is an environmental problem when the runoff reacheswaters. In the international agreement, Baltic Sea Action Plan, the aim is to reduce therunoff of nutrients. Sweden has agreed to reduce its load of e.g. nitrogen to the Baltic Sea.One of the proposed measures is an increased use of site-specific N-fertilization, which hasbeen shown to increase nitrogen use efficiency and therefore also reduce the nitrogen runoff.Either yields are increased with the same total amount of nitrogen, or the total quantityof nitrogen is reduced with preserved yield levels, which is profitable for the farmers.The dynamics of nitrogen leaching differs between top dressing applications above orbelow the economical optimum. There is a consensus about a difference in the dynamics,but not about its magnitude.

The purpose of this paper is to identify and analyze success factors in the integration of students with special needs in regular schools. This will be done through the case study of a nine year old autistic student in a small town public school ? a fairly representative case for the Swedish school system. The data collection methods used in the paper are; three participant observations of the student, and a qualitative interview with two of the student?s teachers.

This thesis has been conducted at Saab Bofors Dynamics AB. The purpose was to investigate if a non-linear missile model could be stabilized when the optimal control signal is computed considering constraints on the control input. This is particularly interesting because the missile is controlled with rudders that have physical bounds. This strategy is called Model Predictive Control. Simulations are conducted to compare this strategy with others; firstly simulations with step responses and secondly simulations when the missile is supposed to hit a moving target.

This thesis deals with the compatibility between analysis software Revit Structure2012 and Robot Structural Analysis 2012. The purpose is to become more aware ofinformation management models to be compatible across different softwareapplications. The structural model is made to be optimal for the compatibility of othersoftware Aim is also to gain an understanding of the transferring methods that exist,and which method is most convenient to use and to examine whether the methodswork in practice. Objective of this project is to make the modeling processtime-efficient for constructors. Models do not need to be structured in severaloccasions in different software; it only needs an optimal model that transfers properlybetween software.The method used in the thesis consist cases where the transferring process isexamined.

Berggrunden på norra Utö har karterats i fält som en del av projektet Metamorphic map of Sweden. Vidare har stuffer analyserats i tunnslip och mikrosond, för att med datorprogrammen THERMOCALC, AX samt Anovitz & Essenses kalcit-dolomit-geotermometer (1987) för kunna fastställa vilken grad av metamorfos området utsatts för. Berggrunden visade sig utgöras främst av pelagiska metasediment som karbonatbergarter och gråvackor, med avbrott i form av felsiska vulkaniter som följer lagringen. I fält såväl som mikroskop indikerade resultaten en relativt låg grad av metamorfos. De geotermobarymetriska uträkningarna som utförs i rapporten stöder detta resultat och bestämmer temperaturen till mellan 430 och 697°C samt trycket 4.5±2.3Kbar, vilket placerar metamorfosen inom ?Amphibolite facies?.

This report describes the development of a sample loader for my diploma work at Q-linea AB in Uppsala. The sample loader will replace the process of loading fluid samples into Q-linea?s instrument for biomolecule analysis. The earlier process was done by hand and was a time consuming and inefficient task.The work was initiated with a design phase where an overview of the system was created. The sample loader will be receiving text commands from a PC that coordinates all the subsystems like pumps and lasers on the analysis instrument.

Can degree of degenerative brain disease be predicted with the help of measurements of cognitive deterioration?Alzheimer?s disease progresses through nerve cell break down in the brain and the simultaneous deterioration of the individual?s cognitive function. This disease is common among elderly persons. This thesis examines if the level of deterioration of cognitive function is associated with different biochemical and clinical markers for degenerative brain diseases. In addition, this thesis examines if the level of decline in cognitive functions vary between groups with different levels of degenerative brain disease.

This paper examines possible applications of fuzzy logic on the field of artificial intelligence in digital games. It describes fuzzy logic in contrast to crisp logic. The paper will give several examples of possible applications of fuzzy logic-based decision making for game AI. These examples include the choosing of weapons for AI agents and the gas-break decision of an AI-controlled car. The paper will also analyze the impacts of game AI which makes decisions based on many factors.

In this study we have focused on how board work is affected by companies growth and development. This research has been conducted through a case study of Teleopti AB, a private Swedish family-owned company, together with theory and literature studies. We have studied the development of Teleopti since its founding in 1992 until today and what impact this company's development has had on Teleopti's board work and composition during the same period. Through the study we came to the conclusion that Teleopti's board work has gone from being supportive and advisory to more professional with a higher degree of board involvement. This change has been caused by the reduced information asymmetries, the increased need for board's expertise, the new board dynamics and the CEO change caused by the company's growth..

The purpose of this thesis is to examine value creation in networks. Based on a case study of Livebookings Network, an online booking service. This thesis has an explorative nature. As a theoretical framework we use theories on value and network dynamics. By combining these theories we develop an operationalized framework that we use to analyze our empirical findings.

Bakgrund: Förstoppning är ett av de vanligaste symtomen från mag- och tarmkanalen och att drabbas av förstoppning kan vara en hemsk upplevelse. Tillståndet påverkar personen både fysiskt, mental, socialt och existentiellt, vilket leder till försämrad livskvalité. Syfte: Att beskriva vilka icke-farmakologiska åtgärder som finns för att förebygga förstoppning hos äldre personer över 65 år. Metod: Studien genomfördes som en allmän litteraturstudie där vetenskapliga artiklar söktes i databaser på Internet och manuellt i referenslistor. Åtta vetenskapliga artiklar inkluderades i studien och dessa analyserades och utformades till ett resultat.

This study examines a case of cooperation between banks, commerce, police and the municipality of Skövde, which in a project has the target to reduce the use of cash by 15 % in the city during 2011. The purpose of this study is to increase the understanding of the importance of cooperation in which different actors come together to reach a common goal, such as speed or interfere with an ongoing change, while they must meet their own interests. In this study the case of cooperation has been studied by using a qualitative approach. The methods used in this study are participant observation and a group interview as well as personal interviews. The theories underlying the study revolve around the concepts of collaboration between organizations with similar interests, changes in society, conflict and resistance to change..

The purpose of my study is to examine if the total study results differ between music classes and regular classes. Are there higher grades in music classes? If so, what are the causes for this? I chose to make an inquiry at two schools in different town districts, with music classes. At those schools I also collected data of pupils grades, and was informed by the principals and the music teachers about the activities. The number of respondents were ninety.The inquiry showed that the grades were markedly better in music classes, and that you can see great differences in well-being, parental engagement and ambition level, compared to regular classes.

This work is a product development of a product which facilitates enduro drivers swallowing fluid while driving. My own experience of the problem and a custom survey gave me some frames and requirements of how such a product would look. To obtain the different concepts the method of brainstorming was used where I outlined the various proposals. The basic concept was that some kind of pump would build pressure in the liquid and when the user opens the nozzle the liquid will come out without the need to use the mouth to suck. The screening phase consisted of two steps.

The credit rating industry is a complex and fascinating industry. Its history stretches back more than 150 years and has gradually increased in importance. During its history the dynamics of the industry have changed. The extended-principal-agent model was developed by synthesizing different principal-agent-relationships into one model. This model provides a holistic understanding of the credit rating industry and illustrates the interdependence between the different relationships.
