Stump wood is a hot alternative when the heating plants demands more and more forest fuel. The aim with the study has bean to calculate the costs in four different systems for transportations of stump wood, examine if there are any differences in fuel quality for the stump wood in the different systems, analyse if the fuel quality in stump wood is affected with the time it lays by the road side and how much space the stump wood demands on the road side. To calculate the costs for the different systems a system analysis was carried out, where some of the costs were collected through field studies on Holmen Skog stump experiment and other costs were collected from literature and contacts. Data for the fuel quality study was collected from Eons heat plant in Norrköping. Data for the study of how much space stump wood takes along a roadside was collected from field studies.

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.

In this essay I examine the causal relationship between confidence in institutions and growth in Sweden 1989-2002. By examining the causal relationship between these two variables, valuable indicators of the causal relationship between trust and growth can be obtained. The institutions which are used in this essay are chosen according to the theory on institutions for public administration building trust and social capital. The chosen institutions are primary schooling, the police and medical service. A Granger causality model is used to measure the causal relation and the results from the tests show that there is no causal relationship between growth and confidence in institutions.

Ur ett historiskt perspektiv har hedgefonder som grupp klarat sig bra i finansiella kriser, vilket tyder på att deras strategier och förvaltning fungerar. De omgärdas av friare placeringsregler än traditionella fonder vilket gör att korrelationen med marknaden (SIXRX) är låg. Eftersom dagens ekonomiska kris är den värsta på länge är det intressant att undersöka om hedgefonder lyckats även i denna kris. Syftet är att ta reda på hur hedgefonder med sitt säte i Sverige har presterat i den nuvarande ekonomiska krisen, i jämförelse med hur de presterade under ITkrisen. Förklaringar till hedgefondernas prestationer söks i deras förutsättningar och strategier i relation till varandra och andra fonder.Resultatet av undersökningen visar att hedgefonder med sitt säte i Sverige har presterat sämre i den nuvarande krisen än under IT-krisen.

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%.

Syftet med denna uppsats har varit att pröva en kombination av fyra olika metoder för att utvärdera ett IT-system. Metoderna som kombinerades var: processbaserad utvärdering, kriterie- och målbaserad utvärdering av systemet i användning samt kostnad "nytto"-analys. Som underlag för min undersökning har jag använt mig av en fallstudie. För att utvärdera respektive metod har jag använt ramverket NIMSAD (Normative Information Model-based Systems Analys och Design) som är utvecklat utifrån erfarenheter av problemlösning inom aktionsforskning, industrin och konsultuppdrag. Ramverket kan användas för att utvärdera olika typer av utvecklingsmetoder och bygger på fyra väsentliga beståndsdelar (metodens kontext, användare, metoden samt utvärdering av dessa).

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.

The aim of this thesis is to analyse the most common economic effects of countries pursuing trade facilitation. Trade flows are constrained by non-tariff barriers and through trade facilitation these barriers can be decreased. We will study the effects of trade facilitation from a theoretical perspective and evaluate a number of empirical studies. Several different trade barriers will be identified as well as those regions and countries that will gain the most from trade facilitation. We draw the conclusion thatlarge gains would prevail for all countries and that the consumers, businesses and the state all benefit from trade facilitation.

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 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.

Syftet med uppsatsen är att identifiera vilken ekonomisk information som en företagsledning i ett större tillverkande företag förmedlar, samt verifiera om detta stämmer överens med vad produktionspersonalen har vetskap om. Vi ämnar även undersöka vad som inverkar på produktionspersonalens vetskap om denna information. Slutsatser: Vad ledningen vill föra ut för ekonomisk information och vad produktionspersonalen har vetskap om stämmer generellt inte överens. De respondenter som har störst vetskap om den ekonomiska informationen är mer engagerade, känner större samhörighet i gruppen och är mer insatta i företagets ekonomiska situation. Gemensamt för dessa är att de alla har kontinuerliga och täta möten med roterande ansvar för att hålla i dessa samt tillgång till väl uppdaterade anslagstavlor..

1st of may 2003, a new energy system based on electricity certificates, was initiated in Sweden. The purpose with this system, is to stimulate an enlargement of energy production from renewable sources. The electricity system, ist built on that the producers of energy from renewable sources confer a electricity certificate from the government for every produced MW energy from renewable sources. The electricity certificate is supposed to be turned over and with that generate reciepts to the producers. Furthermore there is an obligation for the energyusers und energysuppliers, that means that the users and the suppliers every year the 1st of april got to have electricity certificates in proportion to their energy consumption during previous year.

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.
