This master thesis was initiated with the aim to answer at what level of installed capacity of wind power in the northern parts of Sweden it would be beneficial to improve the transmission capacity from the northern Sweden. During the process of this work the aim has changed to try and create a model that can be used to analyze how well the hydro power installed in the northern Sweden can even out the quick changes in wind power production.To create a good model of all hydro power in northern Sweden is a very large job, unfortunately too large for a master thesis. This report therefore ends with an extensive analysis of the simplifications that have been made and their effects as well as a list of the future work that has to be done.The model that has been created have shown to be effective and produce good results. The conclusions that can be made is that the northern Swedish hydro power have very good possibilities to balance the wind power production. Only a few cases where water have been spilled even though there has been some free capacity has been discovered.

After the tsunami disaster in December 2004 many arguments were heared that one oft the major reasons behind the poor Swedish effort connected to the evacuation and health care of the Swedish citizens in Thailand right after the incident is the Swedish model with independent government authorities. By comparing the constitution, the political decision making tradition by the ministers and the handling of the catastrophe in the tree Scandinavian countries Denmark, Norway and Finland, plus analysing the behaviour of the Swedish foreign and prime minister from a rational choose inspired individual decision making theory the research shows that there is no proof that a constitutional change in Sweden into the traditional model with government authorities controlled by the ministers alone would led to a more effective crisis handling by the government due to crises concerning Swedish citizens out states. Although the research shows that the constitution and the tradition of decision making in the government provides the basic condition of the ministers individual rational decision making.

Risk management is a key competency that is constantly being researched how it can be improved within project management. The risk management process consists of four major steps: identify risks, assess the risks? significance on the project, evaluate and address the key risks and follow up.The majority of companies seem to neglect certain identified risks, and decide not to mitigate if the risk does not cause adverse effects to the business. To counteract undesirable consequences and help organisations to become more effective at managing risks an initial work has been conducted for a risk repository.The project develops a proposal on the design of a risk repository which aim to effectively support a database implementation. The study includes literature studies which resulted in a relational model for database implementation.

The purpose of this study is to investigate how six students at a Secondary School describes interaction patterns among teachers when students express in a way that the teacher perceives as racist and/or xenophobic, by presenting a qualitative interview study. The interviews were analyzed by two opposing models of value education: the traditional and the constructive model.The results show that students divide teachers in different categories based on five qualities: 1) they listening, 2) they accept students' opinions, 3) they allow discussion, 4) they are knowledgeable and 5) they can express their own opinions.These qualities are included in the value pedagogical model for deliberative conversations, whose strategies for interaction aim to create an understanding of different rules and values, thereby creating skills of rules by using a democratic approach. In contrast to this model, the rule-based moral education, in which the teacher uses his authority and refers to rules without giving an explanation for why they occurred, as strategies. .

BackgroundToday a common approach to solve a complicated problem is to assemble a temporary workforce in order to solve the problem by working together within a project. One of the difficulties with working in projects is to maintain the planned budget. Working hours and costs are often exceeded. Many companies presume that any certain project will succeed, a presumption that leads companies not to anticipate risks involved in a project. In companies today there is seldom time for evaluation or moderation of a project, in order to have time for evaluation there is a great need for an adequate planning of the project.IntentThe intention with this study is to create a model for planning, budgeting and evaluation of projects within consultancy companies.MethodWith the help of interviews and discussions within the group Hamnar och Byggkonstruktioner at Sweco has evidence to present a proposal on planning, budgeting and monitoring been developed.ResultsA model has been developed to ease for consultancy companies to plan, budget, monitor and evaluate projects.

Title: Process description of round timber transports ? a case study at Tra?frakt Go?taland ABAuthors: Karl ? Johan Tern, Christian Johansson and Andreas IvarssonTutor: Anders JerrelingExaminer: Fredrik KarlssonBackground: Today the profitability of forest haulers is unsatisfactory. Negotiations on prices are more about the relative strength of the negotiation parties rather than a discussion about actual costs. Adding extensive changes in the forest haulers cost structure has led to insufficient knowledge of whether the negotiated prices really correspond to their costs.Methodology: We decided to carry out a case study at Tra?frakt Go?taland AB, a special interest organisation whose members represent the majority of forest haulers in Go?taland.Purpose: To describe the processes and underlying activities of round timber transports.

Two ecological models of nitrogen processes in treatment wetlands have been evaluated and compared. These models have been implemented, simulated, and visualized in the Modelica language. The differences and similarities between the Modelica modeling environment used in this thesis and other environments or tools for ecological modeling have been evaluated. The modeling tools evaluated are PowerSim, Simile, Stella, the MathModelica Model Editor, and WEST. The evaluation and the analysis have been performed using McCall?s factors for software quality (McCall et al, 1977), a correlation analysis and the Constant Comparative Method (Glaser&Strauss, 1999).

?Liberal Democracy? is a common term in political theory, and it is used as if it had a commonly accepted referent, with both normative and descriptive content. This is certainly the case in democratic theory, where it on the one hand seems to refer to a normative democratic model; on the other hand it is used descriptively, to refer to real-life democracies. The deliberative democratic sub-field is not an exception; on the contrary, the term is frequently used albeit rarely defined; yet the concept it refers to is supposedly developed enough to allow detailed propositions about its citizens?s political behaviour.This essay is an attempt to analyze how Liberal Democracy is used by three deliberative democrats (Jürgen Habermas, John Dryzek and Stephen Elstub), in order to understand the democratic model (or models), whether normative or descriptive, they refer to.

The aim for this study was to investigate if it is less stressful for cow and calves in loose housing systems when separation is made so they can see and touch each other (Physical Contact-PC) instead of just hearing each other (Hearing Contact-HC). The behavior of eight cow- calf pairs (n=4 pairs per treatment) on an ecological dairy farm with cubicle housing were studied for four hours directly after separation and four hours the day after separation. The first four cows that gave birth were used for treatment PC, and the following four cows that gave birth were used for treatment HC. The only selection criteria used was that both cow and calf were healthy. Separation took place 3-4 days after birth and the calves were put separately in two different pens while the mothers were let loose into the cubicle system.

This study is based on a proposition about the legislation regarding sexual offences prepared by a commission initiated by the Swedish government in 1972 which was presented in 1976. The purpose of this study has been to ascertain the commissions views on rape based on their representation of the problem, their presuppositions and assumptions regarding it and future consequences in behavior for victims and offenders of the crime. The key results of this study is that the commission regarded the ?problem? of the then current legislation to be non-consistently with the time being. In their opinion the legislation needed to be loosened from its moral strings and be adjusted to the ?new? sexually liberal era.

Begreppet ekosystemtjänster kan användas för att tydliggöra värdet av landskapets funktioner och därmed underlätta kommunikation mellan markanvändare då olika intressen konkurrerar. Emellertid finns det få studier som inkluderar en kvantitativ eller kvalitativ värdering av ekosystemtjänster på landskapsnivå. I detta arbete har markanvändning och ekosystemtjänster studerats i ett landskapsperspektiv, med Vilhelmina Model Forest (VMF) som studieområde. Den övergripande frågan i VMF är hur rennäring kan kombineras med andra markanvändningsintressen, huvudsakligen skogsbruk. Syftet med studien var att göra en kvantitativ värdering av markanvändningsintressen och ekosystemtjänster.

The thesis presents an optimally designed kinematic structure for a new 6-DOF haptic devicebased on TAU configuration. The configuration of the TAU-2 proposed by Suleman Khan andKjell Andersson [1] was modified and its mobility was verified by using Grübler criterion tohave a 6 DOF. Analytical kinematic models for the inverse and forward kinematics weredeveloped for the haptic TAU configuration to determine a set of optimal design parameters.Kinematic performance indices such as volume of the workspace, kinematic isotropy and payload index, were defined based on the singular values of the Jacobian matrix. The Jacobianmatrix was scaled to homogenize the physical units. The Jacobian matrix dependent on theposition and orientation of the end-effector gives local isotropy and pay load index, so globaldesign indices were defined, which represent the performance of the mechanism in the wholeworkspace.

Concern about personal privacy continues to grow among online users along with the fact that new technologies help online companies to share user's private information. Still the usage of online entities such as social networks and e-commerce sites continue to increase. This raises the question of why online users act in such a contradictory and irrational way.Our study examines what impact one recently developed application called social login, which is provided by several social networks and used by millions of online companies, has on consumer's evaluation of online brands when they are primed for various types of information concerning privacy issues. Our assumptions are built up on the theory of cognitive, dissonance and suggest that there will be no differences in evaluation of the brands due to the human need to rationalize their existing behavior and attitudes when they receive new or contradicting information. The potential effects are measured by a manipulation presented in a survey distributed in an online environment to a sample of users (n=,154).

During the last two decades, technology has developed rapidly. It has become a natural part of everyday life, which we today take for granted. It isn?t until the last few years that technology has quickly become a big part in the school environments. Computers, tablets and other technology is today a big part of the education and teaching.

This thesis explores the changing prerequisites for accountability in terms of Swedish arms export. The study aims to uncover what has happened with the conditions for accountability in Sweden since the responsibility for export control was transferred from the government to the public administration. By investigating how the term ?accountability? has been used in the literature of democratic theory, an abstract ideal model is being created.  Comparing the changed structural arrangements, with each other and the ideal model, it is concluded that the prerequisites for accountability now seems to be in a worse state than they were before..
