In order to continue to be competitive in the current industrial climate, producers must increase efficiency at their plants. Several Swedish companies choose to utilise the principles of Lean production. Tour & Andersson AB (TA) has elected to create their own model using Toyota?s productions system which has been named TAPS (Tour & Andersson Production System). Following two years of working with TAPS the company has decided to introduce Total Productive Maintenance (TPM). Most of the work carried out in the maintenance department today is in form of repairs to already faulty equipment.

The purpose of this thesis is to analyse and propose improvements to the cost accounting system in use at an airline operating on the Swedish market. The choice of study object is based on the airline?s desire to have its cost accounting system evaluated. During the analysis we have identified a number of points where the current cost accounting system does not correspond to its intended purpose. These points include significant groups of costs not being considered in the current system, potential over capacity is not visible and logic connections between distribution keys and the use of resources are sometimes lacking.

Quadrotor UAVs are self-stabilizing, autonomous flying machines that has recently become more popular than ever. Unmanned Aerial Vehicles have their roots in the military, where they were developed for use in reconnaissance and combat. During the last few years, advances in the fields of electronic sensors, electric motors and microcontrollers have enabled smaller designs and autonomic flight control even for private use. The quadrotor, which is the particular kind of UAV we are looking closer at in this paper, has 4 rotors in an X-like formation. This configuration has many advantages such as good lift capacity, non-complex mechanical structure and serviceability.In this project we aquired a current overview of the domain and determine whether it is possible to construct a quadrotor UAV designed for use in a WISENET sensor network on a low budget and short time schedule.Based on existing community project AeroQuad, a quadrotor is constructed with a budget of about 500 euro.

In Sweden approximately a half per cent of the population have diabetes mellitus type 1. Self-care responsibility is a part of the treatment. Orem?s self-care theory has been used as theoretical framework. The purpose was to describe what it means to be young and have diabetes mellitus type 1.

This is a case study about the effects that disasters have on social work. The case in question is the fire in Berga village, Kalmar, which took place the 12: th of October 2011. The aim of this study is to describe the ways in which Kalmar worked crime preventive towards young people before the fire and after. The study also aims to specify if, and how the disaster affected the crime preventive work with young people. In this study we define the fire like a disaster and disaster has the ability to create changes in policy.

Today's global market means that raw materials are sought and bought from all over the world. This creates an higher demand for a well-functioning supply chain. In our thesis we have studied a large paper mill in northen Sweden which experiences issues with flow of raw material. Our aim has hence been to examine which aspects affect the flow of raw materials to the mill, and how these can be adressed using an IT-system. The question we sought to answer was; What factors are important to consider and how do these affect the ability of an IT-system which will support the flow of raw material at the paper mill? We have found that the problems are strongly connected to the low amount of information sharing between the mill and the suppliers.

Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.

The purpose of this study was to examine whether a L2 learner could correct or imitate structures of the language that they could not produce in written production defined by processability theori levels.The Informants had Arabic as their mother tongue. The study showed that the ability of correction developed slower than the capacity for imitation and the ability to written production. The ability of the correction developed by the duration of the stay. The result was a confirmation of theory formation in processability theory. Corrective elicitering could be developed into a useful diagnostic tool in the classroom and thus provide an education that followed a natural learning order according to processability theory by Pienemann.Keywords: processability theori, imitation, correction, written production.

There are different ways of developing a second language. The purpose of this qualitative study is to investigate whether and possibly how music, focused on singing, can improve the development of Swedish as a second language. Through interviews with three vocal teachers, from three different schools in Sweden, and observations of one of the vocal teachers, information about how they work and think about the subject has been collected. The vocal teachers teach groups of second language learners by singing songs made especially for second language learning. The vocal teachers consider singing beneficial in the development of the pronunciation and improvement of the prosody, which affects the students? capacity to sound like a native Swedish speaker.

A philanthropist needs long arms- An investigation on how to illustrate difficult wordsThe feeling of not understanding all the words that I read made me initiate the project of investigating the capacity of drawn images to increase the understanding of difficult words. I?ve been working with my own personal understanding and skills in illustration.My aim was to reflect on the function, composition and manner of my illustrations. I wanted the images to be clear enough to explain and function as a help for memorizing the words but also open enough to give them a new dimension. One of my conclutions is that my way of changing the original shape of a body in my drawings, by giving it new functions such as longer arms, helps me to explain the words clearer and deeper.

Abstract: In this Master's thesis our aim is to study the situation and process regarding the decision to use outsourcing of the media acquisition function in a Swedish public library. By using New institutional theory, focusing on ways of organising and values in the organisation we are able to analyse this phenomenon. Skot-Hansens theory about three different culture political argumentation schemes, humanistic, sociological and instrumental (or market oriented), gives us the opportunity to place statements and facts into a functional theoretical context. The market oriented scheme is further clarified with the concept of New Public Management. The role of values in the institution, regarding aims and goals is stressed.

In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.

Because of increasing demand of power on Malmbanan the capacity of the existing wires which supply the trains must be increased. This increases the stress on the existing poles and for this reason the system for supplying the loads along the railway is to be removed from the poles and be replaced by some other system. This thesis is a study on a two-level low voltage (1 kV and 0.4 kV) electrical system with the aim to investigate if it can be an alternative to the system used today taking into account the voltages, fault currents and costs.In this thesis the following tasks have been performed:? Gathering of data? Description of basic theory? Loadow and fault current calculations of the system with MATLAB? Life Cycle Cost estimate of the system? Analysis and conclusions from the resultsThe results show that the new system can be an alternative to replace today's system. The simulations and calculations show that the voltage drop is at an acceptable level and that the fault currents are large enough to supply a safe disconnection if a fault occurs at the far end of the system..

Sweden is one of five nations in the world manufacturing fighter aircrafts. Highly advanced technology is needed in order to develop a fighter aircraft. When developing advanced technology, new applications, other than those initially intended occur, spin-off. Some of Sweden?s largest companies are spin-offs from the fighter aircraft industry.

This hermeneutic case study examines how and why an insurance company?s output has been affected by a CEO-succession. The authors pay specific attention to three activities; changes in personnel and organization structure, handling of media and change in customer focus. It is shown that the CEO was able to influence the company?s activities and this discretion was primarily created through her relational capacity.
