The Swedish government has introduced a goal to reduce the energy intensity by 20% to the year 2020. To reach this goal actions need to be taken throughout the energy sector which includes residential and commercial buildings. This thesis considers the possibility to reduce the energy usage in a building located close to Uppsala. The analyzed building is a combined office, cafeteria and entrance and was completed about half a year before this project started. Therefore the measures presented for a more energy efficient building are presented as measures for future constructions.Simulations have been made in VIP-Energy, a dynamic energy calculation program.

The progress in the field of technology is often described as massive and its development has had a great impact on the social development (Vetenskapsrådet, 2012). As a result of the digital evolution, there has been a change in the way customer and company interact (Normann, 2011). The traditional way for players to interact with each other required an interaction human to human (ibid), a mode of interaction that now can be replaced or supplemented by todays technology and often Internet-based solutions (Salomonson et al., 2013). These technological solutions, the technical interaction, are often referred to as self-service systems. These systems enables the customer to carry out the tasks previously performed by the company (Hilton and Hughes, 2013).

Background: The most energy efficient houses today are so called passive houses. These houses achieve high energy-efficiency partly by having well insulated walls. U-value describes the amount of heat transfered through a building element, the more insulation, the smaller U-value. A typical passive house wall have a U-value of 0.10 W/m2,°C. The passive houses are primarily made as small family houses and not as a block of apartments.

I en konkurrenskraftig omvärld, finns det ett behov hos företag av väl integrerade informationssystem. Systemen har till uppgift att se till att aktuell information i verksamheten kommer alla till godo när personalen har behov av den. Idag har företag standardiserade affärssystem till sin hjälp för att hantera den information de har behov av i sin verksamhet. Studien har haft som syfte att beskriva hur anskaffningsprocessen kan se ut på olika företag och att besvara följande frågor:·       På vilka grunder togs beslutet om införskaffande av ett nytt affärssystem?·       Har ledningen varit involverad i anskaffningsprocessen?·       Ledde implementeringen till ett system företaget blev nöjda med?Studien har gjorts med en kvalitativ ansats, där halvstrukturerade intervjuer användes för att samla in empiri.

The purpose of this thesis work was to develop an automatic fault detection system for surveillance of bearing temperature in hydropower turbines. The parameters used except the bearing temperature were cooling water temperature and cooling water flow. A simple static model based on data sampled every minute was developed to estimate the bearing temperature. Then a detector for detection of change in bearing temperature based on the CUSUM-algorithm was designed. Since the amount of data was very small the developed model was too uncertain to be used in a working system.The designed fault detection system showed to work well for the available data.

Pigs are often mentioned as relatively intelligent animals when compared to other nonhuman species. Despite this knowledge, the vast majority of pigs are kept under conditions that lack opportunities to satisfy their cognitive needs. Therefore, a need to evaluate the present scientific studies about pig cognition was acknowledged, in order to evaluate to what extent the knowledge is applied in the husbandry of finishing pigs. If a considerable lack of application was determined, suggestions about how to use the obtained information to improve pig welfare were also to be made. A synthesis of the present literature was made, and it could be concluded that a considerable amount of studies had been carried out in the present area. The pigs of today appear to have the same behavioural and cognitive needs as their ancestor, the wild boar.

An introduction to the complexity which surrounds the matters of land in the northern parts of Sweden was the purpose of this thesis. The agriculture colonization, the delimitation and the development of forestry and mining business were big events which are shown from the view of property rights. The situation of the Lappish people and how their situation has changed through the history was the main theme of the thesis. Hopefully this thesis will also serve as a support while reading for example investigations published by the government and judgments by courts. Supply to the resources of nature has always been decisive for the survival of humans.

Denna avhandling avser produktutvecklingsprocessen för ett upphängningssystem tillhörande ett banddrivet fordon. Syftet med systemet är att tillåta fordonet nå högre hastigheter. Det ska också tillåta dämpning och viss nivellering vid körning i kuperad terräng. På så sätt blir fordonet smidigare och föraren utsätts för mindre helkroppsvibrationer.I samarbete med forsknings- och utvecklingsavdelningen på BAE Systems Hägglunds AB genererades ett antal koncept på upphängningssystemet. Genom att använda listan av produktspecifikationer som BAE Systems tidigare tagit fram tillsammans med exempelprocessen beskriven i Product Design and Development valdes ett koncept att analysera mer detaljerat.

We live in a stressful world and a demanding society where the ability to quickly adapt is one of the most important and most difficult challenges of today. A fairly new phenomenon called intranets has evolved to meet this challenge, however many examples of corporative intranets are stories about failures and systems with poor usability. This study focuses on how the user oriented approach to systems design affected upon a system development process of an Intranet, solely developed within a company, and how it impacts on the intranets popularity among the employees in the company. The study starts not from the literature but from a survey, which is based upon the Delphi method. Which results were used for further in-depth research about the subject, by interviewing three representatives from the company.

När en kommersiell hamn byggs ut fordras omfattande muddringsarbete för att säkerställa ett brukligt djup för sjöfart. Då stora delar av muddermassorna ofta är förorenade av tungmetaller och miljögifter krävs särskilt omhändertagande av dessa. Traditionella omhändertagningsalternativ består av att deponera massorna på särskild avsedd plats på land eller tippa till havs, något som inte tillåts för förorenade sediment. En relativt ny metod är stabilisering/solidifiering (S/S) som innebär att muddermassorna behandlas med ett bindemedel för att sedan kunna användas som fyllnadsmaterial i exempelvis kajkonstruktioner. Dessa alternativ behöver noga vägas mot varandra med hänsyn till ekonomiska och miljömässiga aspekter.

Today all buildings contain some form of home automation. It might be heating controlled by athermostat or motion detectors controlling outdoor lighting.This paper,The Intelligent House, deals with the planning of a house in Kiruna, in the north ofSweden and further immerses itself in home automation or intelligent control in single-familyhomes. The house has been entirely planned, from layout to structural design and plumbing.The purpose of the paper has been to investigate the possibilities in home automation in singlefamilyhomes and to choose a suitable home automation system for the house being planned.The system has been designed and the costs and energy savings have been calculated.The system chosen for the house is called KNX and is the largest system for home automation inSweden. It is used to control heating, ventilation, lighting and alarm systems in the house. Is hasbeen found that KNX is very expensive and that the amount of energy, possible to save in thehouse, using the system, is relatively small.

Comfort analyses regarding human induced vibrationsIt is not too common among civil engineers in Sweden to perform comfort analyses considering the vibrations caused by human activities. In addition, the Swedish standards lack requirements to be used for comfort analyses in design of floor-systems. The demand for large spans in combination with slender slabs, is today a reason to investigate the floor-system constructions, in order to prevent disturbing vibrations and oscillations.The purpose of this thesis is to create a guide for how a comfort analysis, considering vibrations, should be implemented. Göran Svedenbjörk who is an expert in structural dynamics has been interviewed where he presents his latest project Värtaterminalen and answers some questions about vibrations due to human activities.Floor-systems, consisting of concrete slabs supported by steel or concrete beams, have been investigated with simulations in the finite element program Abaqus. In the simulations, the influence of various factors on the natural frequency of floor-systems and the acceleration level caused by dynamic loads, is studied.

The Library of Uppsala University has decided to change their classification system from the Swedish SAB system to the American Dewey Decimal Classification. One of the main reasons for this decison was that Kungliga biblioteket also has made an exchange between these systems. Due to that, the national bibliography of Sweden classifies Swedish documents according to Dewey Decimal Classification and the SAB system is no longer maintained. A transition to Dewey Decimal Classification will enable Swedish librarians to import foreign catalouge posts and classification codes and will provide them with a common standard between their libraries and other libraries due to the use of the same international classification system. It is disputed whether the Dewey Decimal Classification is equally suitable for all subjects.

A recent development in the field of accounting has been an increasing use of fair values in financial reporting. In 2005, this development was reinforced in Sweden by the adoption of the International Financial Reporting Standards. The aim of this thesis is to discuss the problems related to the use of fair values, through a case study of the Swedish investment bank Carnegie. In May 2007, Carnegie announced that the result had been overly stated by 630 MSEK, due to the valuation of derivatives within the trading department. The empirical material consists of documents produced in the legal process between Carnegie and the Swedish Financial Supervisory Authority.

Rwanda is one of the poorest countries in the world and about 70-80 % of the population lives in rural areas. The land is strongly affected by land erosion which makes it difficult for the agriculture and food production. Agroforestry is a system where tree plantation is combined with livestock- and crop production. The system provides soil fertilization and binds the soil together. Some of the trees used in agroforestry systems are also used as fodder.
