Bakgrunden för denna studie är problematiken kring beslutsfattande. Tidigare forskning visar att en individ dagligen fattar en mängd medvetna och omedvetna beslut. Dessa beslut faller sig olika utefter vilka erfarenheter, preferenser och känslor individen har och hur detta påverkar individen vid köp av dyra sällanköpsvaror. Syftet med studien är att identifiera faktorer och personlighetstyper som influerar köparens beslut gällande dyra sällanköpsvaror..

The aim of the present study was to evaluate the effects of large amounts of straw in the farrowing pen on thermal regulation of the newborn piglet in different weight classes. 20 sows were given 15 kg of straw in the farrowing pen 2 days prior to until 7 days after parturition. A control group of 18 sows had no straw in the pen. 6 litters from each treatment were observed. Measurements of piglet body temperature were made at 0h, 2h, 4h, 8h and 24h after parturition. At ?8h? the body temperature of the piglets in the Straw group were significantly higher (P=0,0149) than the piglets in the Control group.

Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.

Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.

How can you do a right measurement of culture as well as with other social sectors and with what can culture contribute when it comes to a town´s development? We found out that in Linköping the regional federation Ostsam recently (2005) started mapping the region's creative centers in order to look into the spreading of the culture in the county, and then use the uniqueness of the culture as an advantage in society- planning contexts. The reason was that both municipal - and State directions detected that the culture has a broader importance when it comes to building up society and infrastructure than earlier considered. This is called Cultural planning and is the foundation- method that Östsam used when working with their new projekt The creative sector. The outcome of the Östsam study resulted in an exciting study basis to work further on with and to examine through own demarcations and directions.This research manages the matter of the creative sector as an extension to the cultural sector.

The banking industry is a fundamental part of the economy in Sweden. Despite its importance, the competition and the concentration level within the Swedish banking sector is relatively unexplored. This paper aims to examine the development of the concentration level in the Swedish banking sector during a period of ten years, 2003 to 2013. The examined banks in the study are the four largest banks in Sweden; Handelsbanken, Nordea, SEB and Swedbank, and four selected niche banks, ICA banken, Ikano Bank, Länförsäkringar Bank and Skandiabanken. In order to examine the development in percentage change, there are six selected variables; loans, deposits and borrowings (both public and households), net interest income and return on equity, which are observed during a period of ten years.

This thesis deals with query formulation in full text retrieval. The variables studied were query expansion and query structur[INS: e :INS , and the aim of the thesis is to study their co-effects on retrieval performance in a probabilistic system. The expansion was made with synonyms, and the structure by expressing facets and phrases. The study was performed using QPA, Query Performance Analyzer, which includes InQuery retrieval system and a sub-collection of TREC documents with its topics. The measurement used was precision at 11 DCV points.

This master thesis includes a description of how a number of sensors are put together in a sensor platform. It also gives a description of how localization and mapping has been performed with data collected from the sensor platform. Localization is a prerequisite for most of the tasks that can be requested from an autonomous mobile robot. In many situations the GPS signal is not available and hence an additional localization system is required. One approach is to apply localization based on landmarks extracted from the robots surrounding.

The aim with this paper is to study Karl Popper?s view on realism and relativism. Further aim is to see whether those ideas have been consistent over the years. The paper argues that Popper since his first interest in philosophy has taken a realistic and antirelativistic attitude. Only his arguments for this position have been developed to meet his critics.Common sense speaks for realism but can neither be proven nor refuted.

In this study we examine how much latency is required in an RTS-game (Real-Time Strategy) before the player quits the game. In the study latency is simulated in the games Age of Mythology and Starcraft: Brood War with the program WANem, and then the testplayers are asked ?Do you want to quit because of latency??. This data is then gathered and compiled into graphs to show the results. These results show that the limit for when players want to quit differs between the two games and that there are two factors that play into this.

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

As trucks are getting more and more advanced, information about their weight has become a key factor for controlling them in a more fuel efficient and safe manner. Knowing the mass of a heavy duty vehicle in real time has been a difficult challenge for the truck manufacturers. With the processing power for electronic control units in trucks steadily increasing, more advanced algorithms for calculating the mass has been developed, but at the moment there still is a wish for better performance.Since there is a lack of good information regarding the external forces acting on the vehicle, forces that depends on the slope of the road, foundation of the road and the wind, the methods have to be able to disregard these. Such an approach, based on an indirect least square solution, has been evaluated in this thesis. The results have been promising and based on these a recommendation about further evaluation has been made..

This report is about helping Q-Med AB in Uppsala to start its implementation of uncertainty of measurements analyses in their manufacturing department. Prior to this, the company relied solely on personal experience or did not take this uncertainty into consideration at all during different kind of measurements, which means that some of the processes that the company previously believed were within specified acceptance limits, will actually fail when considering these sources of uncertainties.Q-Med AB needed some sort of instruction to help the company, in a systematic way, to investigate different types of disorders that are affecting all kinds of measurements. This instruction includes a short summary about measurements and uncertainty of measurements in general and a detailed procedure about how these uncertainties are going to be handled in their daily work.The goal was to be able to use this instruction to systematically locate, eliminate (when possible) and analyze all kinds of disorders when measuring. Q-Med is using a lot of different types of instruments when measuring different types of quantities, including temperature, mass, pressure and density. This instruction will hereafter be used for every instrument, regardless of quantity and type of instrument.The instruction is tested through 4 different kinds of measurements, for mass, temperature and humidity.

Många av de verktyg som används för mätning och styrning av prestationer i offentliga organisationer är hämtade från privat verksamhet. Dock har offentliga organisationer ofta andra typer av mål och styrning än privata företag, vilket försvårar måluppföljningen. Denna uppsats syftar till att få en förståelse av Trafikverkets användning av prestationsmätning samt tillämpning av mål- och resultatstyrning. Vidare kan studien ge ett bidrag till ökad kännedom kring hur mätning och styrning av prestationer sker inom en statlig organisation. I en fallstudie som innefattar intervjuer och dokumentgranskning studeras hur mätning och styrning av mål fungerar i Trafikverkets största investeringsverksamhet.
