Turbinkretspump system - Kraftvärmeverket i Borås
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.
Får vårdpersonalen bästa tänkbara IT-stöd? : Kartläggning och analys av informationsflödet mellan EPJ systemförvaltning och vårdpersonal
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.
Efter bankkrisen: Vad är notan för skattebetalarna nu?: En uppföljning av Peter Jennergren och Bertil Näslunds studie från 1998
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.
Lost World : Home of the seven and a half legged tree
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.
Implementering av lean i ett gjuteri med låga volymer och hög variation
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.
Datorbaserad analys av enzymdesign för Diels-Alder reaktioner
This thesis has been focused around the Diels Alder reaction with the goal to design an enzyme catalyzed reaction pathway. To achieve this goal computer aided enzyme design was utilized. Common traditional methods of computational chemistry (B3LYP, MP2) do not do well when calculating reaction barriers or even reaction energies for the Diels Alder reaction. New calcu- lation methods were developed and tested. This was the focus of the first part of the thesis, by choosing a small system, extensive and heavy calculations could be done with CBS-QB3.
AUTOMATISERING AV PAKETERINGSPROCESS
The aim of this thesis is to investigate if an automation of the manual packaging process at Legosan AB is profitable. Legosan AB, located in Kumla, performs subcontract work of dietary supplements and medical products to companies within Europe. The chapterportal robot is used in the other. As there are several options in the choice of packaging robot the suggestions of improvement are divided into two different designs. Other machines and equipment necessary for the different suggestions of improvement are showed and their measurements are presented.
Konstruktion av upprätningssystem för CICLoPE
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.
Internprissättning på lån inom multinationella koncerner - En kvalitativ studie av det svenska rättsläget
Due to the growth of multinational concerns during the last decades, with large parts of international trade involving such corporations, the field of transfer pricing, including financial transactions such as internal loans, have received a great deal of attention in tax legislation. The internationally accepted foundation for transfer pricing is the so called Arm's length principle, expressed in Swedish law through the "Korrigeringsregeln". In the Diligentia court case, the concepts of transparency and control were given a crucial role in the calculation of an Arm's length's price of interest rates. The Swedish tax agency interpreted the ruling in that case as if a parent company always can be assumed to enjoy sufficient transparency and control to reduce the risk on their debt obligations. A great deal of uncertainty therefore surrounded their position and to what extent the Diligentia-ruling could be cited as precedent.
Rengöringsmaskin av produktionslina : Rengöring av band i produktion
The project was carried out with SwedSafe AB, engaged in hearing and manufacture of earplugs. Since the company is a world leader in the sale of these products, it is important that they keep a higher level of quality of these products.Production of earplugs is currently a automated manufacturing process that is divided into four conveyor belts and one of the conveyor belts is what will be affected in the project. The belt affected during this process is exposed to various elements such as filling, closing, fermentation and extraction of products. Because the belt gets dirty, degraded products and the work environment is affected. To increase the quality of products and improve the working environment requires an automatic cleaning process, which collects dirt from the belt.The aim of the project is to design a machine that prevents the belt from becoming dirty, preserve molds clean and improve the working environment without disrupting production.

Är goodwillnedskrivningar värderelevanta - En studie av den svenska aktiemarknaden
This study investigates the value relevance of goodwill impairments for equity investors in Swedish listed companies. We provide insight on whether goodwill impairments are value relevant before as well as after the implementation of IFRS 3 and IAS 36. We express market value of equity as a function of book value of equity; net income excluding goodwill impairments and goodwill impairments, using the Ohlson valuation model and Hellström's price regression. Our findings suggest that goodwill impairments are statistically value relevant for equity investors. Prior to the implementation of IFRS 3 and IAS 36, our findings imply that equity investors respond negatively to goodwill impairments.

Den positiva hälsovågen : En kvantitativ studie om hälsofrämjande arbete
The construction of buildings and paved surfaces changes the natural water balance.Precipitation generates surface runoff and storm water instead of infiltrating into the soil.Storm water has come to be considered as a major source of pollution in lakes and streams inthe vicinity of urban areas. Reduction of pollutants in storm water is a key action in order toprotect sensitive recipients and maintain high water quality. Storm water is traditionallytransported by storm sewers to the nearest recipient. In recent years the approach to stormwater management has changed; storm water should primarily be disposed of on site, throughlocal disposal of storm water, LOD. LOD is created by a combination of the function ofseveral smaller local facilities and the general sewer system.
