One of the environmental problems today in seas, lakes and streams is eutrophication. This is often caused by nutrients such as phosphorus (P) and nitrogen (N) that leak from agricultural areas. A measure to partly prevent the nutrient discharge is to construct or restore wetlands.In order to control the efficiency of nutrient reduction of existing wetlands in the county, the administrative board in Västra Götaland wants to find different criterias for reference wetlands. These reference wetlands should represent other wetlands and be used in future evaluations of reduction of nutrients and design of constructed wetlands. According to the administrative board in Västra Götaland the reference wetlands should have a catchment area of about 50 hectare consisting of at least 70 % arable land, to represent wetlands created to remove nutrients.

This thesis intends to analyse conditions for a successful implementation of consociational democracy, as a democratic model in Afghanistan. The lack of critical reviews regarding the democratisation-process in Afghanistan initiated the purpose of this study.Lijpharts democracy model was used as the basis in the comparative study. Along with empirical evidence regarding how the complex process of democracy in Afghanistan is progressing, the study investigated whether the identified conditions occurred or not.The choice of which democracy model to use can be crucial for the democratic possibilities to even survive and become established in conflict-affected communities. The principle of consociational democracy is that it is an empirically based normative model that aims to organise the state in a way that works against the risks of majority domination and oppression against the minority.The empirical case study revealed that a majority of the conditions were not met, which then can counteract the possibilities for consociational democracy in Afghanistan. The study has critically examined the prospects for the success of consociational democracy in Afghanistan, and it can be assessed that there is a limited probability for a successful applying of this model..

This master thesis holds a modelling in Simulink for a physical model of a main battletank tower, a three-phase induction motor and some mechanics. The aim of this work is to connect an earlier project at AerotechTelub, named StabSim to another called Eldris. In StabSim it has been made a Simulink model of the align and stabilisation system in a main battle tank 122 and in Eldris it has been build a physical model of a main battle tank tower. In this thesis the models that differs between Eldris and a real tower is changed in StabSim, and the parts that only exist in Eldris is added, for example a torque generating system which purpose is to make the model to behave like a real tower in control application, although it only has half the inertia as a real tower. The thesis even includes proposing a calculation of the torque that the torque generating system will actuate at the model..

This master thesis concerns the subject of a reference service named Book-a-librarian. The service makes it possible for the library-user to indulge in a subject with the help of a librarian after having made an appointment in advance. The main purpose of this thesis is to study the function of it. The methods used are a mix of literature and empirical studies to be able to comprehend and explain the practical nature of the service as well as placing the service in a theoretical framework. The empirical study is performed by a questionnaire, where librarians working with the service are asked to participate.

This bachelor thesis is about communication problems and treatment during the reference interview. The purpose was to investigate the reasons of why users? information needs are not always understood by the librarian and what to do about it. I have also investigated what kind of skills that can be useful for librarians to have and how a librarian can act in a way that makes the user feel welcome during the reference interview. The method I used was a literature study and an own study through interviews of library users.

Purpose: The purpose of this essay is to study how the hotel chain Radisson SAS works with prolonged customer relations with their business clients, with other words the clients that have business agreements with them.Methods: This study will contain an inductive approach and qualitative methods.

In 2006 the government assigned the Council of Cultural Affairs the task of making an update, consisting of 50 literary titles, to be added to the existing list called Alla tiders klassiker ? en klassikerserie för skolan (All-time classics suited for school).      The idea of ??a literary canon can be considered to be a tool for transferring socially, historically and culturally constructed norms and values ??from one generation to the next in order to create and maintain a common frame of reference. The common frame of reference affect the individual's thoughts and actions as well as their sexual desires and their own perception of self as a sexual being.

My goal with this Project was to create four pictures which de¬scribed four different emotions. The purpose of the project was that the pictures would be placed in a psychology department and they could use them as a starting point for a discussion about the patients? emotions. My personal purpose was that I wanted to create pictures in scale 1:1 in an analogue fashion, and try to learn more about how people see and feel about pictures. What kind of thoughts can a picture give you? Can I create a picture which can be used as a platform for a discussion? Can I make a picture which describes an emotion? The making of the pictures started with developing ideas and then I took photographs of my friend Joel, in different situations and moods, which I used as reference for my paintings.

In Trollhättan municipality approximately 700 school bus stops are in service. To ensure high quality of the performance of school bus operations, with focus on traffic safety, it was decided to conduct a survey of bus stops including assessments of risks.This master thesis aims to identify the factors affecting road safety at bus stops and pedestrian connections, and to conduct an inventory and analysis of selected sites in Trollhättan municipality. The work also aims to show examples of how risk assessment should be performed in future studies. A risk analysis model provided by the Swedish Transport Administration is supplemented and used in a field study. The risk assessment is based on, inter alia, traffic flow, visibility distance, lighting, speed of traffic and the presence of bus shelter.

The purpose of this paper is to investigate the possibility of replacing data from highspeed filming (Qualisys motion capture) with data from Inertial Measurement Units (X-io technologies), when used to run a model of torso and pelvis in OpenSim. Qualisys motion capture data is used as the golden standard to validate the result visually and with Bland-Altman plots.In order to obtain comparable data experiments are conducted where both methods of collecting data are used simultaneously. Data from the IMU's then need to be processed in Matlab before it can be used to run the OpenSim modell. Several Matlab programs rotate the IMU data to a static reference frame, filter and integrate it, then create viritual markers that correspond to Qualisys' optical markers.The conclusion is that using IMU as a method for collecting data can replace Qualisys in some applications, but not in ones that require high precision. However, this paper only begins the examination of IMU's and there are most likely improvements to be made..

Background: The difference between the market value and the book value of the companies has dramatically increased. One explanation is that the inflow of capital on the market has increased. Another explanation is that companies have a larger share of intellectual capital. The question is how this has influenced the company-valuator's use of valuation-models? Purpose: The purpose of this study is to find out what relevance the substance valuation model has, the DCF-model has, and also discover new valuation-models, among company-valuators.

The United States use of Unmanned Combat Aerial Vehicles (UCAV) or drones for targeted killings of terrorists has been on the rise in recent years and the method has become the core element of president Obamas strategy in the war against terror. This study examines the deterrent effect of targeted killings on terrorism using UCAV/drones as a method of counterterrorism. Building on the literature on counterterrorism, UCAV, targeted killings, deterrence theory and statistics on terrorism the study provides a case study of the CIA drone operations in Pakistan between the years 2004-2010. The goal has been to analyze drone operations and the extent of terrorism from the beginning of the drone campaign until 2010. This as a means of identifying possible trends in terrorism activity due to the occurrence of drone strikes.

AbstractWith increasing population and increasing demands for comfort and thus an increase in energy demand, it is necessary to examine various energy-efficiency measures. This work deals with the ability to control the flow through the heating system to achieve the desired comfort with as little energy as possibleA heating system contains of different parts, roughly speaking, you can divide it to three main components: Heat source, Distribution and Heat emitters. All components are working together to bring heat to the building. What is examined in this report are different ways of adjusting the flow and supply temperature and how it affects comfort and energy use in a building.At today ?s date the conventional method is to use a high flow through the heating system, which affects pressure drop and cooling of the fluid.

Foreign invested SMEs have recently become increasingly interested in China. The enterprises are in this report categorized as second wave companies since they follow the footsteps of previous pioneers, of which mostly were larger companies. The ambitions of the SMEs are either to sell products on the ever expanding Chinese market or to utilize the potential of low cost production for global markets. The existing literature is fragmented and solely based on the experience of larger companies. We believe that SMEs are facing new and different challenges, and thus a new generic theoretical frame work is desirable.
