Energy consumption is at present a major political issue, and numerous projects that comprise many nations are currently in process to increase energy efficiency and bring down energy dependency. As a member state of the EU, Sweden now faces the challenge of implementing substantial energy-saving measures until the year 2016. One of these measures is the project ?Green Islands? financed by the EU that intend on creating sustainable islands in areas around the Baltic Sea. The Archipelago Foundation leads the project that concerns the Stockholm archipelago, where focus has been placed upon decreasing energy usage in businesses and services on Utö among other islands.

The purpose of this essay is to examine how administrative officers at the Swedish social insurance agency experience and deal with the goal conflicts they may experience. Furthermore, the purpose is to gain a greater understanding on how they perceive their role in the implementation process, and their position as the link between the citizens and the state. Two potential conflicts are examined; between quantitative goals and performance measures and those more qualitative and hard to measure; between economic values such as cost efficiency and productivity and democratic values such as the rule of law. The other conflict examined is that between implementing and following the laws set forth, take into account the individual needs and interests of the citizen. The theoretical framework consists of Lundquist?s theory on public officers as the guardians of democracy, which means that they should not only implement laws and rules according to political intentions, but also make sure that the democratic values and principles are followed in the relationship between state and citizen.

An automatic milking (AM) system should be combined with some form of controlled cow traffic to minimize the time spend on fetching cows to milking and to increase the milking frequency. By restricting the hours spent on pasture per day you optimise the AM system use during pasture period. A reason for this is becuase cows do not return to the stable for milking during night which cause that the milking unit stands empty those hours. In organic production it is required that the cows should be able to graze a certain amount of daily dry matter (DM) intake on the pasture. In the county of Dalarna where the farm is located the yield of the pasture is about 3000 kg DM per grazing season and hectar.This means that the pasture area should be 14,25 hectare to 57 milking cows.

To measure losses in a transformer with today?s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%.

Tomo Hugglink (TOMO Skog) is an innovation for harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.

Tillväxtteori är ett centralt inslag i nationalekonomiska studier. Lika centralt i finansiella studier är frågan om vad som förklarar aktiekursers utveckling. Ett eventuellt samband mellan dessa är av intresse att undersöka. Om tillväxt visar sig förklara en del av kursutvecklingen hos aktier är detta mycket användbart vid val av investeringsstrategier. För att undersöka om ett samband föreligger används en modifierad modell av teknologispridningsmodellen till grund för att skapa ett index som visar hur nära man befinner sig sitt steady state (det jämviktsläge en ekonomi rör sig mot på lång sikt).

Den här studien beskriver en konflikt kring en bergvärmetrend för bostadsrättsföreningar som uppstått i Uppsala under hösten 2010 och våren 2011. Konfliktens parter är å ena sidan bostadsrättsföreningar som valt att satsa på bergvärme för att i första hand minska sina uppvärmningskostnader från fjärrvärmen. Å andra sidan majoriteten i Uppsala kommuns miljö- och hälsoskyddsnämnd som är oroliga för trendens miljömässiga effekter, framförallt för elförsörjningen, och förespråkar fjärrvärme. Utifrån två teoretiska perspektiv har jag satt konflikten kring bergvärmetrenden i ett större historiskt och samhälleligt sammanhang. Jag har prövat möjligheten att se konflikten som en konflikt kring fjärrvärme som ett stort tekniskt system med referens till teknikhistorikern Thomas B. Hughes.

This empirical work and base has been to analyze the government?s investigation (SOU 2008:27): the future road ? a reformed high school, which led to the high school reform that the Swedish government introduced as proposition (2008/09:199) about: Higher demand and quality within the high school. Skolverket (part of the Swedish government) has worked with the development of this steering document within their own mission Gy2011 in connection with the high schools during the transition. The reform comes into effect 1 of July 2011. This led to the main purpose to ask questions what high school principals and teachers think of the reform and to what extent it effects the high school programs, the examination system, what impact they see on the individual and the demand from society, and to some extent what the respondent´s answers about the government?s definition of what the higher demand and quality in the reform signify.

This thesis aimed to study the interaction between an educational technology system and its users and give suggestions for design improvements. The technology system is called EDIT (Educational Development through Information Technology) and has been developed and applied at Linköping University?s Faculty of Health Science. EDIT supports Problem Based Learning and enables scenarios to be presented through the World Wide Web. The study was divided into two parts.

The print- and mailroom at Gefle Dagblad (GD-tyck) is handling an increasing amount of commercial jobsalong with the newspaper production. Investments have above all been done in the mailroom to be able tooffer commercial costumers a higher degree of finishing and there are plans to expand further in the commercialmarket. GD-tryck is of the opinion that they need to secure the quality of their production to be ableto do such expansion, which is the reason why a quality system of some kind may be appropriate. Howeverthere are no plans to certify such a quality system according to ISO 9001:2000.In this exam report the present methods of working have been analysed from a quality perspective.Suggestions on how GD-tryck should be working with quality development is presented in the fields whereshortage of quality has been discovered. The suggestions taken together do not form a quality system butcan be looked at as ideas of approach to quality fields that have to be developed if a working quality systemshall be accomplished.Many of the quality fields that have been discussed do not have anything to do with technical qualitydirectly but are in some degree requirements for a working quality system.

The transformed municipality ? Economic and social growth in Örnsköldsvik 1997-2007Author: Kristina HanssonThis thesis focuses on the economic and social growth in the municipality of Örnsköldsvik. It is a single case study and the municipality is studied through economic theories concerning regional growth in the period of 1997-2007. The aim is to analyse whether these theories, such as Åke E. Anderssons and Ulf Strömquists K-society, and other more or less microeconomic assumptions, also are applicable in smaller local contexts.

The aim of this master?s thesis is to investigate how Paul Feyerabend?s anarchistic theory of knowledge can help our understanding of bibliographical classification and to analyse how epistemological assumptions are manifested in bibliographic classification. Paul Feyerabend?s anarchistic theory of knowledge and science is the theoretical approach of this thesis. The first part of the thesis consists of an introduction to bibliographical classification and epistemology.

This rapport contains an examination of the energy consumption of a kindergarten, which areas that have the largest impact on the energy consumption and what can be done to reduce those areas in ways that are relatively easy and profitable. It is also analyzed if it is possible to reduce the energy consumption from today?s consumption to a consumption that fulfils the demands placed on low energy houses by FEBY.The focus has been on reducing the energy consumption of the areas ventilation, heating system and hot water system, since those seemed to be the easiest ones to affect and since the building is quite recently built.There are different kinds of ventilation systems, at the moment the building have a CAV-system, which means that the ventilation is too high during large parts of the day. There are different ways to manage the ventilation system, for example presence detection, humidity sensors, CO2 sensors, temperature sensors and season adjustment. Many of those are in the end dependent on CO2 sensors to guarantee a good indoor climate, therefore the focus have been placed on this system.

In this report a systematic working procedure for risk classification of processing equipment from a maintenance point of view is described. How this system has been worked out is also an important part of the report. The classification system is adapted for use in complex processing plants. Preemraff Göteborg has been subject for the underlying study and application of the system.The system aims to give a good overview of the maintenance related risks at the plant. Furthermore, the analysis result is a good motivation for the suggested maintenance activities and as motivation for extended or decreased maintenance resources in total.

The development of IT systems is usually accomplished by some form of system development methodology. It can be performed as the waterfall method, where each phase is completed before the next begins. One of the reasons to follow a development methodology is that the process is more structured, faster and that the product will have higher quality. One risk of not using a system development approach is that the code can be unstructured and difficult to maintain.This paper describes an alternative method in which the development occurred without the use of any system development methodology. This has been possible because there was a clear goal of the program that should be developed.
