Due to their complexity and heavy wear from rail traffic, switches are a sensitive part of the railway infrastructure and moreover expensive to maintain. Furthermore, increasing railway traffic not only accelerates the wear rate but also obstructs the necessary maintenance measures. This paper examines the opportunities for a transition to a long-term maintenance strategy in the Swedish railway network. It contains a study of the maintenance strategy of Banverket, and also analyses statistics of errors in the railway infrastructure. The survey was completed utilising interviews with infrastructure managers, maintenance contractors, planners of railway operations and the Banverket material service department.

The Rya power plant in Borås produces district heating, district cooling and electricity. The plant is owned by Borås Energi och Miljö AB and is run by Dalkia Facility Management AB.In order to get the best heat exchange from the district hot water a pair of twin pumps and a turbine circuit pump are used as return pumps. Turbine circuit pumps are used to increase the pressure through the heat exchangers at the power plant. The pumps are in use when the flow is over 2 000 m3 h-1 and during the summer when re-cooling is used to improve the effectivens of the heat boilers.Since the pumps, that are parallel connected, rotating at a fixed rate per minute, the pressure is regulated with regulating valves. This report shows that during the 4,300 hours that the pumps where in use, energy corresponding to 590 MWh was wasted.

In health care today at Uppsala County Council the daily work involves spending time at the computer. IT-systems were implemented to support and aid the care givers in their work. Around these systems there is a support organization to support the users in using the system. The aim of this thesis is to investigate this organization in terms of how well it works and how successful it is in helping the users. This has been done by investigating the flow of information trough the organization and by focusing at the role of IT-coordinators with responsibility for support, process development, education and statistics.

The globalization that has occurred during the last few years has made it more important for companies to have a well-functioning logistics system. Customers demand more options, which lead to an increased flow that creates greater demand regarding packaging and transports. Diverse logistics costs are nowadays a substantial cost for many companies. Therefore, more effort is aimed at optimizing transportation to lower these costs.The purpose of this project is to create a user-friendly calculation of logistics costs that illustrates how the costs vary, depending on how the flow is structured. This is done by examining which aspects that affect the total logistics costs and by mapping which aspects that should be included in a calculation of the logistics costs.Literature studies have been carried out parallel with empirical studies at Scania's production unit, MC, in Oskarshamn.

During the Swedish banking crisis in the early 1990?s, the government paid out 65 billion Swedish kronor to save Swedish banks from bankruptcy. In the process, two banks left the private sector to be taken over by the state. This thesis builds on a study from 1998 in seeking to quantify the financial end result for the Swedish government from the subsidies. Taking a cash flow approach and accounting for the time difference, it starts with the money paid out during the years of crisis and subtracts the money that has since been returned to the government by successful management of the relinquished assets.

The main focus for this essay is to describe the relationship between human and nature through a material investigation that takes its shape through sculpture. With the help of a fairytale-like story the reader can share the creation of the sculpture and how my thoughts flow through the process that will result in an exam project. Rooted in earlier projects I discuss the crash between civilization and the wilderness as well as talking about the likeness of the creative process and child play. I also discuss the body's place in the forest and the loneliness that we humans created that has cut us off from the rest of the creatures and plants in the forest. My aim is that in the final piece I will create a fiction place where these can be joined together again.

This thesis paper discusses the results of a survey which was conducted to investigate the potential usefulness of mobile apps in the maintenance department at Perstorp Specialty Chemicals AB. The paper contains four sections, a theory section, a method section , a section that explains the functionality of the app, and finally a results section where the results and conclusions of the survey are discussed. The theory section explains and discusses relevant terminology used in the computer science field and in the maintenance industry. The theoretical model used in this paper is also discussed. The methods section gives a stepwise description of the project and a description of platform and software used.

At the department of Electronic Warfare Assessments at the Swedish Defence Research Agency in Linköping one of the activities is modelling and simulation of the duel between a robot and a target. The aim with this Master's thesis is to develop a simulation model of an hovering helicopter. First a theoretical description of the forces and moments acting on an helicopter is given. Then the equations of motion are derived. These equations are simplified to be valid only for a hovering helicopter and the result is a mathematical model.

Valmets own foundry in Karlstad has during a long period of time had problems being profitable. The goal today is to turn this around. Today there are three different productionlines; engine blocks, Yankeecylinders and components for the wind turbine industry. This master thesis has focused on examining if value stream mapping is a useful tool to use in a foundry, and therefore outside the typical manufacturing industry. The target has also been to evaluate if there is a possibility to improve the flow in the foundry and also the results.During the 20 weeks this work has been done at the foundry data has been collected and analyzed.

Title: Argument in favour of and against private health care ? A scenario for a future health care with a possibly new Government Authors: Jessica Andersson, Nina Gunnarsson Supervisor: Thomas Danborg Department: School of Management, Blekinge Institute of Technology Course: Bachelor?s thesis in Business Administration, 10 credits Purpose: To describe the problem with privatizing of the health care by analyse the arguments in favour of and against private health care and describe a scenario about a future health care with a possibly new Government. Method: Qualitative Grounded theory method, categorizing secondary facts in order to get the complete picture. Results: The market for private health care will increase by a possibly new Government.

Sjuksköterskor inom akutsjukvården har ett varierande yrke. Ingen dag är den andra lik och av sjuksköterskor krävs snabba beslut och ett lugnande arbetssätt. I ett rum kan en patient vårdas för en fiskekrok i fingret medan patienten i rummet bredvid är döende. Detta kan göra att personalen mår dålig och blir stressad vilket kan leda till brister i omvårdnaden mot patienterna. Syftet med studien var att undersöka och beskriva sjuksköterskors upplevelser av avlastningssamtal.

Hot och våld inom ambulanssjukvård är ett arbetsmiljöproblem såväl nationellt som internationellt. Ambulanssjukvården är den första länken i vårdkedjan och ställs inför många olika utmaningar varav hot och våld kanske är den största av dem alla då personalen som är där för att hjälpa istället är den som behöver hjälp. Forskningen inom området är begränsad och uteslutande kvantitativ vilket är ett problem då fenomenet är en högst subjektiv upplevelse. Syftet med studien var att beskriva ambulanspersonalens erfarenheter av hot och våld inom ambulanssjukvården. Metoden var empirisk med kvalitativ ansats och datainsamlingen bestod av intervjuer.

Today there is no way of measuring or simulating turbulent flow in high Reynolds numberenvironments. The computational power required to simulate these conditions is not expectedto be available for several decades so instead the CICLoPE project aims at solving thisshortage by the construction of a long carbon fiber wind tunnel in which real measurementscan be made. To do accurate measurements it is of importance that the wind tunnel, 0.9 metersin diameter and 110 meters long, is as straight as possible.This master thesis treat the design and construction of a device which may be used to align thetunnel along a reference laser beam. A design is presented which allows the pipe to be alignedwithin about a quarter of a millimeter along its entire length. Contents span over severalscience fields such as physics, mechanics, control theory and electronics.The result is a theoretically correct design.

Denna uppsats syftar till att analysera relationsmarknadsföringens roll vid offentlig upphandling. Den kommer även att försöka genomlysa till viken grad en relationsmarknadsföringsstrategi är genomförbar, samt hur detta kan vidareutvecklas för att skapa konkurrensfördelar. För att uppfylla detta syfte har en fallstudie av företaget SWEDE (Swedish Emergency Disaster Equipment), vilket verkar inom ett nischsegment av sjukvårdssektorn, närmare bestämt akutsjukvård/sanering genomförts. Fallstudien har genom en kvalitativ metod med utgångspunkt i grunderna inom modern relationsmarknadsföring undersökt vilka problem, samt möjligheter ett företag på en marknad vilken kontrolleras av Lagen om offentlig upphandling ställs inför.Vidare har andra teorier som stakeholder mapping varit en teoretisk grund för att identifiera viktiga aktörer och deras roll i den offentliga upphandlingsprocessen. De grundprinciper vilka Lagen om offentlig upphandling bygger på har presenterats och diskuterats ur fallföretagets synvinkel för att se hur de kan tänkas begränsa eller möjliggöra en framgångsrik relationsmarknadsföringsstrategi.Utifrån de genomförda intervjuerna, vilka haft för avsikt att skapa en djupare förståelse för det studerade problemområdet, drar jag slutsatsen att fallföretaget strävar efter att använda sig av relationsmarknadsföring i den mån det är möjligt utan att bryta mot Lagen om offentlig upphandling, då detta riskerar att resultera i juridiska påföljder.
