Analys och förbättring av en mätenhet för laddning av elfordon
Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.

Balanserat styrkort : Att förmedla vision och strategier inom divisionen för flygtrafiktjänst vid svenska Luftfartsverket
The purpose of this essay is to investigate how well vision and strategies communicates from division level to underlying business unit levels with focus on the Balanced Scorecard Concept. The investigation was carried out within the ANS division and two of its underlying business units at the LFV Group (Swedish Airports and Air Navigation Services). ANS is responsible for the air navigation services in Sweden and the production of the services is carried out of the business units AER (En Route) and ATA (Tower and Approach). With Air Navigation Services means supervision and conducting air traffic mainly within national air space. The purpose of the services is to insure that air traffic could be carried out in a safe way.The Balanced Scorecard was introduced for the first time in the beginning of the 1990´s.
Är det en enkel konst att återvinna för rullstolsburna i Örebro kommun? : En deskriptiv observationsstudie
Bakgrund Dagens samhälle ställer allt större krav på den enskilde individen att bidra till ett hållbart samhälle, där återvinning av förbrukade material är en del. Samtidigt talas om tillgänglighet för alla individer i samhället och lika rättigheter.Syfte Studien syftar till att undersöka hur förutsättningarna i miljön ser ut vid återvinnings-/miljöstationer för rullstolsburna i Örebro Kommun.Undersökningsmetod En observationsstudie av miljöfaktorer har gjorts utifrån egen utarbetad checklista med grund i bland annat bedömningsinstrumentet Housing Enabler samt rekommenderade mått från svensk lagstiftning angående byggnormer för tillgänglighet. Urvalet skedde genom bekvämlighetsurval.Resultat Observationerna av återvinnings-/miljöstationerna indelades i åtta kategorier, utifrån typ av station. De hinder som observerades var för höga/låga kärl, otillräckligt manöverutrymme, hindrande trösklar/trottoarkanter, tunga dörrar utan automatik och tunga lock/luckor på återvinningskärlen.Slutsats Samtliga observerade återvinnings-/miljöstationer innefattade miljöhinder för rullstolsburna vilket påverkar möjligheten till självständig återvinning. .

"Digi"-war - En uppsats om att utveckla en digital handledare för ett komplext tärningsspel.
This rapport aims to examine the difficulties in presenting a complex game in a way that will invite new players by making the game more accessible. We discuss and present our process on how to create an application named ?Digi?-war that is easy and fast to, both, learn and use. Our solution to this issue includes RFID-tags and readers together with four buttons, as input devices. This simple input device, placed in a gun-type control unit, aims to provide an intuitive interaction..
Automatisk lockmekanism : från idé till prototyp
Wavecraft AB develops medical equipment for heating of organic synthesises. The heating is done with microwaves, which improves the process in both speed and accuracy compared to the more traditional methods where heating elements are used. This report discusses the developement of an automatic lid mechanism for one of Wavecraft's product prototypes. The company assumes that the final product will be integrated by customers into fully automated systems, and the upgrade from a manually to an automatically controlled lid is therefore an important step in the product's developement process.The first stage och the project was an idea generation process. The ideas generated here were organized into five different concepts of which the best one was selected through the use of a concept matrix.
Informationsfrihet och IT-användning i demokratifrämjande syfte
The potential of information technology as a means to invigorate democratic practise is constantly under discussion. Regardless of the differing opinions as to the most suitable way to utilise IT, there are certain democratic core values that have to be considered. One of these is freedom of information, defined by us as the right of every citizen to seek, obtain and express information. The aim of this study is to explore whether the use of IT as a means to enhance democracy can strengthen the citizens right to freedom of information. As an instrument for analysis we use an article by Jan van Dijk, professor of communication science.
Lika makter leka lika? Sanktioner eller dialog, varför skiljer sig USA respektive EU handlingsplaner från varandra angående Irans kärnvapen?
In this thesis I will discuss how US respectively EU general international security policies are formed with the scientific theories Rational Choice and Cognitive theory in mind. I?ll discuss how come US tends to go towards a more sanction orientated strategy while European Union seems to prefer a dialog and diplomatic problem solving strategy. I?ll exemplify respective security strategy through the qualitative cases study of Iran and analyse why they have taken different cores of action while trying to solve the problem with Iran's alleged nuclear weapon.
Investeringsprocesser i storbanker : en undersökning på tre svenska storbanker
There are no general working processes that can stand for how all the investment process is preceded in the organization of major Swedish banks. It is not a question of investment process but rather a question of, investment processes. How these investment processes operates depends totally on the type and size of the current investment, which unit that is operating the processes and what situation the bank currently finds itself in. There is a written form that describes how the different processes should be operated and which capital budget models that should be used but the usage of these forms can be questioned..

Forest enterprises have always searched for ways to improve efficiency. For the past few
years there has been an emphasis on stock-keeping levels. Increased demand for fresh
round timber and the need to decrease the amount of tied-up capital has made the forest
industry reduce its inventory levels. This has brought on a higher demand on the timber
supply from the forest management districts concerning both delivery in time and
assortment output. As a result, the flow of timber has fluctuated a lot with serious
consequence for the timber supply during 1994.

Ett hem eller två hem: hur vuxna skilsmässobarn tolkar och beskriver sin uppväxt mot bakgrund av den boendeform de vuxit upp i efter familjeupplösning
The break up of the family unit leads to new living arrangements and significant changes for children. This can be an extremely upsetting experience for a child, especially if the child is old enough to understand what is happening. New living arrangements can effect a childs fundamental sense of security as well as having consequences later on in life. The object of this research paper was to examine how a group of seven people (children from split families who are now adults), interpreted and described their childhood in relation to the living arrangements they grew up with after the breakdown of the family unit. The main question areas we have examined are: How have the interviewee's living arrangements during childhood affected their understanding of themselves today? In what way has the adult's present day lifestyle been influenced by the split up of the family that they grew up with - using their own words? How do the children from split families describe and interpret concepts such as family and marriage, based on their own experiences? Our research was conducted with the help of seven people from split families who are now adults and who experienced different types of split family arrangements as a child ? permanent residence with mother/father or alternate living with both parents.
