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.

Navigering i Habermas världsdimensioner : en fallstudie i bedömnings- och betygsförfarande inom praktisk idrottsundervisning

Aim: The purpose of the study was to investigate how the assessment and grading is designed and practiced in the practical courses of physical education at GIH - the Swedish School of Sport and Health Sciences, along with how it could affect newly graduated physical education teachers? ability to assess and grade students. The study was based on Habermas?s system and life-world theory.What view occurs concerning proficiencies, basis for assessment and marking among teachers who are responsible for examinations within physical education at GIH?How is the examination structured within physical education at GIH?How are skills and proficiencies among assessment and marking further mediated to students in the teacher education at GIH?Method: The case study was realized by performing qualitative interviews with a total of four teachers at physical education at GIH. Additionally, syllabi were text-analyzed to improve the validity of the study.Results: From the results we found that the teachers experience marking as a complicated assignment, where particularly the didactic ability but also the practical ability form a formative and summative assessment.

Intelligenta Switchar

This master thesis has been carried out on behalf of Stoneridge Electronics AB and is an investigation ofhow intelligent switches can replace the traditionally used direct controlled switches. The concept ofintelligent switches is that the switches contain electronic identification components which, by connectingthem to a network, give the same function independent of the location of the switch. This infers anincreased flexibility and configurability which can be a great advantage in development, production andcustomization in the commercial vehicle industry. Especially in the current situation when commercialvehicle manufacturers provides more and more functions and dashboard configurations.LIN (Local Interconnect Network) is a network protocol introduced in 1999. It is a simpler and lower costcomplement to CAN (Controller Area Network) and is adapted for applications where the demands forbandwidth are lower, for example reading sensors and switchers.

Att måla läppstift på grisen: En fallstudie om den interna interaktionen mellan Inköp och Miljö i arbetet mot hållbar utveckling

During the last years, the importance of sourcing in firms has increased. Globalization, fierce competition and an increased level of outsourcing are common explanations to why firms have highlighted the potential to realize savings and the value creation that the Purchasing department can generate. One trend that follows in parallel with globalization is an increased pressure from society on firms to take responsibility for the impact that its products and services have on the environment. This responsibility creates even more attention as outsourcing involves trade with suppliers in low wage countries, where the level of environmental and social responsibility is not always satisfying. The Purchasing department, the firm?s interface with suppliers should therefore, together with the firm?s Environmental department, play a key role in the firm?s contribution towards sustainable development.

Analys och förbättringsförslag för riktkopplardesign

Ericsson develops a new stripline directional coupler. Its design is described in appendix B and differs from the directional couplers Ericsson uses in current products. The new directional coupler will be used for transmission power measurement in future UMTS 3G base stations.The most important parts of directional coupler theory are presented. It is necessary to study this theory to understand how the coupler works and how it should be designed to get good performance.Optimal directional coupler termination component values to get high directivity and broad directivity bandwidth have been investigated.The trim screws trim ranges have been studied.A simple analysis of serial production performance when termination component tolerances are taken into consideration has been done.The resistance components reactive (inductive/capacitive) characteristics at 2.14 GHz have been analyzed.The directivity performance limitations of the directional coupler, when Ericsson?s band pass filter is connected, are investigated.Design changes leading to better performance are proposed.

Modellering av en panna med rörlig rost :  

The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.

Adaptiv katalysatormodell för reglering

This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.

Livscykelanalys för koldioxidutsläpp från flerbostadshus

Today, about 15 to 20 percent of Sweden?s total emission of carbon dioxide can be traced to the household sector. By examining apartment blocks in a life cycle perspective, the origin of the carbon dioxide emission has been charted and analyzed. This information has been used to create a computational model that calculates the total emission of carbon dioxide from a specific apartment block. The results from the analyzed apartment blocks indicate that both the use of energy and the emission of carbon dioxide have been reduced since the 1960s. Through the examination of building materials, it is possible to lower the emission of carbon dioxide that origins from the construction phase of an apartment block.
