MCNP-modell för beräkning av neutrondos och DPA på reaktortanken vid Ringhals 2
In this report an MCNP (Monte Carlo N-Particle) model is described for the reactor vessel at Ringhals 2. The model is validated against the specific activity in neutron dosimeters, extracted in 1977, 1984 and 1994. The validation showed that the calculations of the model are within the requirements of a maximum of 20 percent uncertainty for every neutron dosimeter except one, extracted after the first cycle. The uncertainty of this cycle was mostly due to the operation data rather than to the MCNP model.The model has been used to investigate various questions concerning radiation damage. The reliability of the traditional measure of radiation damage, fast neutron flux (En > 1MeV) has been evaluated. This has been done by taking the ratio for this and another measure of radiation damage, DPA (Displacement Per Atom), for various positions and layers.
Kristianstad Kommuns destinationsutveckling : Utvecklingen utifrån tre hållbara aspekter

The municipality seeks knowledge both by sharing their own and takes part in other municipalities in the development process..
Inkluderande ?garskap i varierande demokratiska kontexter: En j?mf?rande fallstudie av svenskt utvecklingssamarbete med Rwanda och Tanzania
This thesis investigates how recipient countries' domestic type of democracy affects its
inclusive ownership in international development cooperation. This is done by examining
Swedish development cooperation with Rwanda and Tanzania during the period from 2010 to
2014, a time when ownership - a concept which emphasizes recipient countries' leadership
over its own development - was a central part of the international development agenda. The
two cases were selected through a most similar case design where the value of potential
explanatory variables was similar, except for the recipient countries' types of democracy.
Furthermore, the case study uses a comparative analysis to analyze strategies and reports
done by SIDA and the Swedish Ministry of Foreign Affairs. Previous research focuses on the
exclusion that national ownership can result in, in undemocratic national contexts. The main
argument for this should be seen as the fact that ownership can not be representative if the
power of the recipient's development agenda is limited to a decision-making elite.
Marknadsföring av ungdomsverksamhet på folkbibliotek
The purpose of this bachelor thesis is to examine the methods public libraries can use in order to market youth services. It is also a chance to evaluate an untested marketing model adapted to public libraries. Young people are one of the most difficult groups to attract to the library and thus librarians need adequate methods to deal with this problem. We have interviewed librarians, carried out observations and examined documents in accordance to the triangulation method. Before one can begin marketing the libraries one ought to know of how marketing is done and the principles behind it, therefore we have given a simple explanation of marketing and marketing theory.
What goes up must come down - Modelling economic consequences of wind turbine decommissioning
At the time being there is limited experience within turbine decommissioning in Sweden and the economic effects are unknown. Despite this, there are expectations that revenues generated by sales of materials will cover decommissioning costs. The model developed identifies thirteen parameters that vary between different types of turbines and that affect the economic consequences of decommissioning. The three most important parameters are turbine location, tower material, and the scope of decommissioning. Trends in the wind energy industry show that these three factors are developing in a manner that increases decommissioning costs dramatically.
Leder icke användarcentrerad systemutveckling till låg användbarhet?
Within system development users have rarely been involved or received much attention during the development. Most of the times, the primary focus within system development lies on insuring functionality, rather than making the system usable. The literature specifies that a non user-centered approach can contribute to a product with low usability, which can lead to an ineffective and unsatisfactory experience for the end users.The purpose of this thesis is to begin an investigation to see if the use of non user-oriented system development methods is a possible cause of low usability in the final system.To achieve the purpose of this thesis, we have conducted a case study. Within the case study we examined the usability of a time reporting system. The case study included seven minor studies; an investigation concerning the development of the system, an expert evaluation of the system, interviews and observations of users, developed paper prototypes and executable prototypes, both which user testing was performed on.The result of this study shows that by working with user-entered methods, the usability in the time reporting system increased after the design had been revised.
Spridning av bekämpningsmedel i banvall : Modellutveckling och känslighetsanalys
The stability of railway embankment is essential for safe transport. In order to ensure safe transport, water should be allowed to freely drain. Furthermore, as the engine driver has to be able to see signs, and people working on the embankment are supposed to easily see flaws on the rails to ensure safety for the passing trains, plants should not be allowed to grow on the embankment. In Sweden there are 12 000 kilometers of railway tracks and 25?30 % of them are treated for weed control every year.
Digital doggy bag : iPhone applikation som tar med dina mat- och dryckupplevelser
In this project an iPhone application for storing food and drink experiences was developed with focus on an easy interaction design. The already existing market of similar applications were studied and evaluated to extract their positive and negative features. Interviews with experts within the food and drink business where made in the pre study to get a good perception of how to divide and categorize the sections in the application. To optimize the usability, workshops with potential users with different technical experiences where continuously held during the development of the design.During the development two variants of development environments where evaluated. The final result of the application was developed in the environment that made the best impression and seemed to be the best alternative.The resulting product has a thought out design meant to be easy to understand, even for the first time users.
Vi vill ocks? vara med! : en kvalitativ teoripro?vande intervjustudie om politiskt deltagande bland personer med fysiska funktionsnedsa?ttningar
This thesis studied which factors affect political participation among people with physical disabilities in Sweden.? The aim of the study was to test how Civic Voluntarism Model should explain the low political participation among people with physical disabilities in Sweden, through deep interviews.? Following research questions has been studied in the thesis:? How can the Civic Voluntarism Model, based on the time, communicative skills and economic resources, explain the low political participation of people with physical disabilities in Sweden??Which other factors, linked to accessibility, discrimination and legislation, are needed to further explain and understand the barriers to political engagement and participation for people with physical disabilities?? Results about treatment, clearer legislation, economic possibilities and inclusion was central. It became important to considered that where is differences in which capabilities where are to political participation. The CVM could partly explain the low political participation among people with physical disabilities.
