There have been changes in Earth?s climate system on both global and regional scale since the pre-industrial era and some of these changes are due to human activities such as the combustion of fossil fuels. This calls for the development of engines with a higher efficiency and less harmful emissions. One interesting concept is the Homogeneous Charge Compression Ignition (HCCI) engine, which has the advantages of potentially low emissions combined with high efficiency. However, HCCI with diesel fuel requires a relatively long fuel/air mixing time to ensure a "homogenous" charge.

Can the Danish "Aftalesystemet", a system with the intention to simplify the use of services within health care, be used in Sweden? This project has investigated the possibility by installing and testing the system and explored its functions to detect any eventual problems. Analyses were made of the system's graphical part and the underlying code to see in greater detail how the communication between units occurred, since no actual documentation of it existed. Discussions with the developers took place regarding how the current system works and how further development should continue. In order to test the system, a completely virtual environment was used.

Anne Charlotte Leffler, Victoria Benedictsson and Frida Stéenhoff were all part of the Modern Breakthrough in Swedish literature. By utilizing Jürgen Habermas theoretical works on communicative action, and Nancy Fraser?s supplementary reading of his theory, this essay makes clear that the authors? struggle for an understanding and a rethinking of social norms in their plays Skådespelerskan (1873), Romeos Julia (1888) and Lejonets unge (1896) can be read as a contribution to the public debate. Dialogue has a key function for female authors during the Modern Breakthrough. Women and mens? possibilities to take part in conversation and argument as equals, requires the professional woman?s transgression and access to the privileges of both public (State) administration ? ?system?, and world of everyday life ? ?lifeworld?.

Syftet med den här uppsatsen är att studera vad som har påverkat spotpriset på el i Sverige mellan åren 1996 och 2002. För att besvara syftet har de variabler som påverkar utbudet respektive efterfrågan, och därmed också spotpriset på el, identifierats med hjälp av traditionell ekonomisk teori. Därefter har en modell utformats och lösts med hjälp av Two-Stage Least Square metoden. De inkluderade variablerna i modellen är disponibel inkomst, pris på olja, teknologisk utveckling, kapacitet samt importerad kvantitet el. Förklaringsgraden på regressionen blev cirka 82 procent vilket tyder på att det kan finnas variabler som påverkar spotpriset på el som utelämnats från modellen.

This report treats a Master Thesis performed at Scania CV AB. The task was to create a computer model of a hydraulic actuator system in the software AVL Hydsim. The system consists of two spring-loaded masses with surrounding hydraulic components. The purpose of the model is to study phenomenon and problems in the system, as well as to be a support in the development of the system. It is not supposed to be used to study absolute values in its current form.

Webbloggens aktualisering i medielandskapet har inspirerat oss till denna uppsats vilken behandlar detta nya fenomen. Främst riktas uppsatsens fokus mot att studera hur webbloggens potential kan användas som komplement till andra kanaler som används för nyhetsförmedling och debatt i det offentliga rummet. Vidare önskar vi finna svaret på om någon demokratisk funktion för webbloggen existerar? Kan webbloggen som kommunikationskanal bidra till att skapa en deliberativ demokrati genom att inbjuda till dialog i offentligheten. Kan den information som publiceras komplettera den traditionella nyhetsförmedlingen?Till grund ligger en kvalitativ studie som bygger på fältstudier på sex bloggande journalister och deras webbloggar.

Den här rapporten har som syfte att utreda vilket eldistributionssystem för offshoreenheter som sparar mest vikt och utrymme. De två elsystem som jämförs är GVAs standard system och Siemens Blue Drive System. Rapporten innehåller en teoretisk bakgrund för båda systemen och dimensionering av systemens kraftkablar samt beräkning av kabelvikter och komponentvikten för systemen. För att uppskatta kabel- rutter och längder kommer ritningsunderlag för GVAs offshoreenhet 7500 att användas.Resultatet visar att GVAs standard system är det eldistributionssystem som har den lägsta totalvikten med 168 ton, GVAs standard system har en vikt som är 101 ton lägre än Siemens Blue Drive System som har en vikt på är 269 ton. GVAs standard system har en lägre ström vilket gör att ledararean blir mindre och i med det blir kabelvikten mindre.

Syftet med detta examensarbete har varit att ta fram badrumsinteriör för företaget Space Interiör innehållande kommod, spegelskåp och högskåp eller motsvarande. Bakgrunden till projektet har varit att uppdragsgivaren önskat att utveckla sitt sortiment för badrumsinredning. Målgruppen för projektet var enligt angivelse personer under 35 år boendes på en yta mindre än 50 m2. Nyckelorden från företaget var smart förvaring samt innovation.Den teori som behandlats i projektet rör sådan som varit relevant för utvecklingsarbetet så som ergonomi, material och dess underhåll, standarder samt det som påverkar det estetiska uttrycket. Arbetet har varit målstyrt och har därför utförts enligt en stage-gate-modell som lämpar sig för denna typ av projekt.

Jämtkraft AB has recently modernized its hydropower station at Hissmofors by replacing four older worn out units with two new units. The generators uses a concept with sliding stator feet to deal with the thermal movements that occur in the stator during operation when the unit is operating intermittently. At other sites, this method revealed shortcomings in the reliability. This has made Jämtkraft AB feel uncertainty about its function and therefore want to investigate it during an early stage. The generators have a built-in monitoring system for the sliding stator feet and by using data from there the function of the sliding stator feet has been investigated. The study focused on how the different stator feet move relative to each other and how the eccentricity and deviation from roundness changed during operation. The results show that there are several indications that the function of the sliding stator feet is not satisfactory.

Emissions of radionuclides to the atmosphere can lead to wet deposition on plants in theevent of rainfall. An increased level of radioactivity in the plants may occur due tointerception and retention of the radionuclides. If the content of the plants is above thethreshold limit value, entire yields may have to be destroyed. In order to preventcontamination or decrease the content countermeasures can be taken. The impact of thebiomass, leaf area index (LAI) and growth stage of the plant on the interception andretention is important to know in order to decide which countermeasures to use.Weather may also be an important factor.In this work the interception and retention of 134Cs and 85Sr by spring wheat, ley andspring oil-seed rape was studied.

The purpose of this essay is to do an ecocritical reading of Vilhelm Moberg?s The Emi-grants from 1949. By asking and answering the three following questions; How does a system present itself, What are the different reasons for emigration; Why does differentsystem fit some well and some not.By using two articles from Green Planets - Ecology and Science Fiction to illus-trate two different views; Different parts value in an ekosystem and The Ship as an ecosystem. I have also created, based on the literary text four different terms concern-ing the dynamic system; Stable, Static, Unstable and Collapsing systems. I have found that all system goes through changes, some drastic, that changes the way the parts of the systems fit with in it.

This Thesis aims to explore how to integrate an IT-system for facilitating anorganizations work with Continous Impprovements.This is done here by examining and analyzing the process within a handful ofcompanies who seem to have been successful with their own implementations. Thestudy is focused on the implementation of one particular system, "System C2".Simliarities and differences between the companies, and the established rule of thumbfor these kind of activities are focused upon. This to emphasis how another actormight emulate some of the apparent success.Part of the core question is found in the title, since Continous Improvement is oftenseen as a relativly low-risk activity, is it then also possible to take a low-risk slow pathto the implementation of such a system in the entire organization?.

When planning new wind farms, the cost for the internal electrical grid is estimated to account for 8-9 % of the total investment cost. On top of that, the cost for accumulated reduced income over several years (due to electrical losses), has to be added. The economic lifespan is relatively long (about 20 years) which means that an error in the loss calculation could lead to a bad decision basis. The accumulated reduced incomes due to electrical losses can be higher than the initial investment cost for the internal electrical grid.Today, Statkraft Sweden is using a template number when estimating the electrical losses in a wind farm. The actual losses are probably lower than the template number which could lead to an unnecessary high loss cost when planning a new wind farm.The aim of this M.Sc.

This thesis aims to develop a control system for measuring electromagnetic compability (EMC). This has meant that a controller designed around an ATmega8 microcontroller has been manufactured and programmed. It has also meant the development of a comprehensive control software in the program MATLAB. The control system has been tested with satisfactory results and can now, monitor and control measurements of the EMC-type..
