In recent years, the Swedish railway track system has been neglected in terms of capacity and maintenance. To adapt the existing system to current traffic load there is a great need for extensive improvement and maintenance. Shortcomings are especially occurring on older embankments running over soft subgrades. To select the most suitable method for reinforcement of the embankment, it is important to evaluate different solutions from a life cycle cost perspective. In long-term perspective, it is often shown that a method with low investment cost causes a higher maintenance cost and a shorter technical lifetime.

The Animal Protection Agency was in 2006, commissioned by the Government to: Evaluate how free range animals in the winter, can be kept and managed with special emphasis to animal welfare. The Animal Protection Agency was closed later in 2006 and the commission moved to the Swedish Board of Agriculture. The keeping of free range out wintered cattle, certain basic requirement are needed: by regulation, cattle should have access to a lying hall or other building that gives protection against aversive weather and wind and should offer a dry and clean lying area. There is a possibility for farmers that get an exemption from this regulation. But cases regarding farms which have had difficulties for this exemption has led to a discussion about if the animals can get the same protection in the nature which is comparable to a lying- hall.

This is important for the companies chance of survival and for them to compete in their markets. This essay will discuss the subject of Scania?s long-term collaboration with their suppliers. The purpose of the essay in this case study is to analyze if a long-term cooperation with a supplier is of essence upon renegotiations of continued collaboration.

Business unit Cylinder at ASSA AB in Eskilstuna are having problem with frictions in their production process. Changes are occurring and older products along with machineries are phased out and transferred to low-cost countries. This opens up possibilities to at a larger extend customize physical flows after production flows. The authors where given the task to analyze the production and find problem areas to improve and to give suggestion on how Business unit Cylinder can work to optimize their production flow.The aim of the thesis work is to come up with suggestions on how to reduce the lead time in production and how the tied up capital can be reduced. In more detail the task included to find problem areas that are counteracting an effective flow, give solutions on new flows for the production of the cylinder core, give suggestions for new stock points for the production and how the production shall be managed and controlled.During the last twelve months ASSA AB has sold over 700 different types of cylinder cores, and the product range is very wide.

In the collections of the Vasa Museum, 100 leather objects have exhibited salt precipitations. The objects, that have previously been impregnated with PEG, have become deteriorated and fragmented due to the precipitations. During a previously conducted study it was established that the precipitations consisted of iron and sulphur. However, it was not established whether they occurred in the leather?s inner structure and no treatment plan was developed.

This master thesis was a continuation of a previous study in the diesel exhaust characterization, which is part of the academical work embedded in the EMIR-1 project. The main objective of this thesis work was to finish the installation and make the proper modifications of the particulate mass measuring system located in one of the engine test cells at KTH, in order to be able to measure the mass of the particles from the exhaust of diesel engines.This experiment requires a diluted flow sample from the exhaust that should be sent to the device that makes possible the measurement of particle mass, called TEOM. In the first stage of this project, the objective was to study and make the proper modifications in the existing KTH diluter because there were several problems to obtain a constant dilution ratio from it during tests.This modifications were made and it resulted in a great improvement in the maximum inlet and outlet flow that this diluter can handle. Therefore another modification is proposed for controlling the inlet exhaust flow so it will be possible to regulate the dilution ratio and make it constant along a wide range of engine loads and speeds.The second and most important stage was to make particulate mass measurements possible by analyzing the frequency signal from the TEOM device. The idea was to obtain the frequency of oscillation from the tapered element in the TEOM, and therefore with the proper correlations, be able to predict the particulate mass concentration in the exhaust flow from the engine.An electrical problem in the TEOM circuit was detected and corrected, so the signal that carries the frequency from the TEOM can be analyzed properly.

It is in society's interest that news is conveyed in a correct and memorable manner. News contributes to general knowledge and increases awareness of other people's life situations. Because of news the population is able to follow and be a part of the political debate. Therefore, it is important that one remembers what one has seen, both in long and in short term, i.e. memorability is a critical aspect when it comes to news.The aim of this work was to study the news form a memorability perspective, that is, how long one remembers the news after watching them.

To support, enhance and, in the future, develop the activity within the county councils in Sweden, IT support systems are currently used to a large extent. The need to document is central to the health care organizations and the counties have come a long way in the introduction of electronic patient record systems (EPR). The aim of the EPR systems is to support the care processes and the clinical professions in their work.This is a master thesis in the area of human-computer interaction (HCI), Department of Information Technology at Uppsala University. The aim of the thesis was to describe and compare the five most common EPR systems in Sweden. The comparison will focus on some usability aspects and on how well they support the users in their clinical practice.

Drivkraften till att människor reser har länge ansetts vara behovet att åka till en geografisk plats för att där utföra någon typ av aktivitet. Med dagens informations- ochkommunikationsteknik (IKT) har vår virtuella rörlighet ökat och således är vardagens aktiviteter inte lika bundna till en specifik plats. Resenärer numera använda IKT till att utföra aktiviteter redan under restiden. Genom att vi då kan använda tiden till fler aktiviteter kan det bidra till att restiden blir värdefull och inte bara en transportsträcka fram till målet. I takt med att det de senaste åren skett en mobil explosion har också tillgängligheten till IKT ökat under resan.Studien syftar till att undersöka vad människor ägnar sin restid åt när de pendlar regionalt och hur de ser på värdet av restiden.

As part of an internship at Ericsson, this report was written to enhance the understanding of how it is to develop a system that is well established at the workplace. To improve an already existing system is not always as easy as many developers may think. In this report the pros and cons of developing an already existing system has been researched and analyzed. Do note that the results are only from one development of a specific system and that comparison of other developments has been made from other reports and not from experiencing it firsthand. It was found that the choices made can have an impact on further developing and it is important to write down what has been done.

The aim of this study is to examine the services offered by the public libraries in the context of distance learning students. I wanted to examine if there has been any discussion among the public libraries on how the new needs and demands affect them. To get a premonition on the development in Sweden I have focused on the public libraries in the province of Blekinge, which in many ways can be looked upon as precursors. Interviews have taken place with the distance learning students contacts at the local public libraries, the responsible librarian and a distance learning organiser at the local university college, the county library consultant and one of the chief librarians. I have reached the conclusion that no thorough discussion on the far-reaching aspects has taken place.

The study examines the price elasticity of demand for cigarettes in the short- and long run in Sweden. The time period for the study is 17 years and covers the years 1996-2012. The results of the study shows that the price elasticity of demand for cigarettes in the long run is higher than in the short run for the Swedish consumers, which is in line with previous studies in the area. The fact that the price elasticity of demand for cigarettes is higher in the long run, indicates that the substitution effect has a significant impact on the price elasticity of demand for cigarettes in the long run. The study was conducted in two parts where the authors investigated the effect of cigarette tax on cigarette prices and in addition the cigarette prices impact on the demand for cigarettes in Sweden.

Traditional financial management has lately been criticized, since it gives inadequate and unilateral information for decisions and strategy of the operation. The purpose of this essay is to investigate if a balanced scorecard is able to work together with a budget and become a stronger control system for the management. Essential theory underlies the gathering of data as well as the analysis, and the empirical investigation is based on personal interviews. The conclusions drawn from my analysis are that two parallel control systems could complement each other?s weaknesses.

In this project the task has been to develop a product that will facilitate an operation for personnel working in a sterilization center. The operation is to steer the front of a loading trolley into the chamber of an autoclave, a so-called docking. The moment is complicated because the margins to deviate from ideal docking position and still succeed, is very small.The principal Getinge's desire was that the product could be retrofitted at the customers on their existing systems. One of the demands was that the product should fit two types of trolleys, one with a adjustable working height and one with a fixed working height. Getinge is supposed to purchase the system from a subcontractor who shall manufacture it and the requirement from Getinge is that the cost of purchase mustn't exceed SEK 500Initially principles, solving the problem was developed.
