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.

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 main purpose with this study was to investigate whether the tree growth differs or not in prescribed burnt areas compared to mechanically scarified. Together with the result from the main purpose, answers of whether it's possible or not to combine nature conservation with tree production in prescribed burnt areas was presented. In these areas the regeneration were analyzed to see if there was enough tree plants to comply with the Swedish Forestry Act regulations terms for approved regeneration. A field survey was conducted at 6 objects, three objects for prescribed burning and three for mechanically scarification. All objects were planted within the same year.

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.

Cnior Mobile AB i Lindesberg utvecklar en mobil trygghetstelefon för äldre. Detta examensarbete går ut på att utforma en handsfree-enhet för denna. Handsfree-enheten ska integreras i larmknappen, som bärs av användaren runt handleden, och har kontakt med telefonen via blåtandsradio. I examensarbetet ingår att välja ut lämplig högtalare och mikrofon, hitta lösningar för smuts- och vattentålighet samt att lösa problem med ekon och bakgrundsstörningar.En högtalare hittades som uppfyllde kraven för smuts- och vattentålighet samtidigt som den hade utmärkt frekvensgång för återgivning av tydligt tal. Vattenavrinning från högtalaren löstes genom att ett sinussvep sänds ut från högtalaren varje gång ett samtal ska kopplas upp.

With an increased demand for biomass based energy and with development of better technique harvest biomass, new possibilities open up. With the possibility to combine traditional cleaning of road?s right of way with biomass harvesting, the work of suppressing tree vegetation could become profitable or at least decrease the road maintenance cost. However, knowledge about productivity and profitability in mechanical biomass harvesting in roads? right of ways are still limited.

På Sandvik Materials Technology, SMT, Rörverk 68 i Sandviken tillverkar man ånggeneratorrör till kärnkraftsindustrin. Rören är upp till 30 meter långa och ca 20 mm i diameter, så när de ska lyftas upp ur ett rörställ där de mellanlagras, kräver det stor försiktighet. Inte minsta repa får förekomma på rören och de får inte bli krokiga. Lyftet görs nu för hand vilket inte är lämpligt ur arbetsmiljösynpunkt. Därför finns behovet av ett lyfthjälpmedel som underlättar för operatörerna.

Background: A large number of companies works as a link between manufacturers and final users. These companies buys and stores goods to be able to deliver when a need comes up later in the chain. The storage could have a negative effect on profitability and therefore places great demands on the management control systems. ABC as a method has been used with some success in manufacturing for over ten years. In wholesale companies the method is not frequently used.
