Several technical solutions are ready to step forward as the new generation of propellant, and this report aims to explore the possibility of commercializing fuel cell cars. The report is based on current research and data from today's technology and engineering solutions that are estimated to be commercially realized before 2020.A mapping of today?s different fuel cell options has shown that the most suitable fuel cell option is the Proton Exchange Membrane Fuel Cell, which uses hydrogen as fuel. The report is focusing on a techno-economic well-to-wheel analysis of hydrogen and the energy balance and costs in a system perspective. The basis for this analysis consists of two centralized methods of production, steam methane reforming (SMR), and alkaline water electrolysis.

Sammanfattning Titel: Lågkonjunktur ? En studie i vilka skillnader som finns för variationen i antal anställda inom IT- respektive industribranschen Författare: Emilio Nilsson, Oscar Kacprzak Handledare: Emil Numminen Institution: Blekinge Tekniska Högskola Kurs: Kandidatarbete i Företagsekonomi Syfte: Syftet med uppsatsen är att undersöka och analysera för hur företagets ekonomiska data för den relativt unga IT-sektorn förklarar antal anställda gentemot hur företagets ekonomiska data förklarar nyckeltalet för en äldre mer erfaren bransch som industrisektorn. Metod: Vi har samlat ihop kvartalsrapporter från 1999 års första kvartal till 2009 års första kvartal för totalt 10 stycken företag som vi bedömt lämpliga för studien, 5 företag från IT-branschen samt 5 företag från industribranschen. Vi har därefter fört regressionsanalyser med antal anställda som Y-variabel och totala intäkter, aktienivå, rörelsekostnader samt rörelseresultat som X-variabler för att finna korrelationen däremellan. Slutsats: De framkomna resultaten från regressionsanalyserna pekar på att det finns skillnader branscherna emellan.

Bakgrund Yrket som operationssjuksköterska är idag den äldsta sjuksköterskespecialiteten men förblir främst en dold yrkesroll på grund av att det utövas bakom stängda dörrar. Yrkesrollen skildrades som komplex och kretsade omkring patienten, samarbetet och den tekniska utrustningen Patricia Benners teorier om sjuksköterskans yrkesutveckling användes som teoretisk förankring i studien. Syfte Studiens syfte var att belysa hur operationssjuksköterskan upplever sin yrkesroll. Metod Studien genomfördes med en kvalitativ ansats och tio semistrukturerade intervjuer utfördes med operationssjuksköterskor från två sjukhus i Sverige under våren 2011. Alla intervjuer spelades in och transkriberades ordagrant.

Purpose: Corporations today see a greater responsibility towards society regarding the environmental impact of their actions, using available transportation options that are more eco-friendly can reduce this impact significantly. Martinsen and Björklund (2012) identifies a set of gaps between supply and demand of green logistics services. This paper aims to address what it is that affects the demand for these alternative solutions and what could be done to increase the usage of them, thereby decreasing this gap.Design/methodology/approach: A quantitative study with six Logistics Service Providers (LSP) and 24 companies that purchase transportation services, all operating in Sweden. Data is collected through semi-structured telephone interviews with people responsible for the purchasing of transports as well as key account managers within the service providing companies.Findings: Just as the LSP?s interviewed in this paper thought, the main focus of the transport buying companies are the costs.

Fallstudien baseras på ett samarbete med Ericsson Operating Expenses Financial Control och syftar till att belysa förväntningar, förväntningsgap och bakomliggande osäkerheter i samband med ett förändrat arbetssätt. OPEX Financial Control är en supportverksamhet som tillhandahåller tjänster vad gäller uppföljning av omkostnader till ett antal affärsenheter och övriga verksamheter inom Ericsson. I ett under hösten 2005 pågående pilotprojekt prövas ett nytt arbetssätt som innebär att linjecheferna tar ett ökat finansiellt ansvar för sin egen omkostnadsuppföljning. Detta medför att ett nytt verktyg och nya rutiner prövas. Studien utgår ifrån intervjuer med fem controllers, varav fyra representerar enheten OPEX Financial Control, samt fem linjechefer.

The purpose of this essay is to describe how Boverkets Byggregler has affected the cost ofnewly built houses from 2003 to 2012, to Boverkets Vision 2025. The purpose is also to findagent-principal relations in the construction sector.When investing in an energy efficient house the operating costs are reduced compared to aconventional house. But due to the lower operating costs, the investment cost rises. In thisstudy, we find out if it is economically viable to invest in an energy efficient house comparedto a conventional house from the customer's perspective.The study's approach has been qualitatively where we in collaboration with Derome Hus hadaccess to three conventional reference houses and a passive house and data that was necessaryto conduct viability assessments on houses. We conducted five interviews with people fromDeromekoncernen and Varbergs kommun.The calculation methods we have used in this study are present value method, annuity methodand a sensitivity analysis.

BakgrundOperationspersonal är den yrkesgrupp inom vården som är mest utsatt för risk för blodsmitta genom frekvent hantering av stickande och skärande instrument samt exponering av blod. Bland operations­sjuksköterskor finns en stark önskan att arbeta så säkert som möjligt för att minska risken för smittöverföring. Det finns föreskrifter, metoder och hjälpmedel för att förhindra stick- och skärskador men få skriftliga riktlinjer och rutiner.SyfteSyftet med den här studien är att undersöka operationssjuksköterskans hantering av stickande och skärande instrument i operationssalen.MetodStudiens design är en empirisk tvärsnittsstudie med en kvantitativ ansats. En strukturerad observationsstudie utfördes på Södersjukhuset i Stockholm. 18 operationssjuksköterskor observerades under 50 operationer.ResultatStudiens resultat visar på brister inom samtliga områden som observerats.

In this paper the effect of capital structure on profitability has been investigated among Swedish companies. The essay intends to examine how the relationship between debt and profitability appear among Swedish companies and if the relationship differs between industries. The purpose is to find out how debt affects the profitability of Swedish companies.A quantitative approach has been applied. The selection was made among companies listed on Nasdaq OMX Stockholm, which resulted in a sample of 207 companies. Several regression analyzes has been formed, based on the independent variable debt-ratio and the dependent variables profit margin, pre-tax profit margin, operating margin, return on assets and return on equity.

To be examined in hospitals can sometimes be perceived aspainful by children. Therefore there is a need for something,which can distract children?s attention from their perceivedpain. During my graduation project, I discovered a designopportunity to work with suspended ceiling systems inexamination rooms, as there is not much to look at whilebeing examined.The result, Twig Ceiling is an interactive nature-inspiredbacklit module with colored LEDs. Twig Ceiling has onelayer of pattern that is visible when the module is not litand the second layer of pattern appears when turning onthe light.

During its lifetime, a road goes through a number of different stages; pre-study,inquiry of the road, work plan, documenting stage, building stage and operatingstage. The operating stage is the one that takes the longest time and costs themost. Those have a tendency of becoming unnecessarily high because the projectengineers don?t always take the management and maintenance prerequisites intoconditions.To decrease the management and maintenance costs, the Swedish RoadAdministration SouthEast has been in need of a work procedure that makes theroaddesign engineers take the management and maintenance of the road intoconsideration. This shall be achieved by a checklist where the most commondesigns that lead to increased management- and maintenance costs are compiledand listed.Through interviews with project leaders in management, the most commonproblems have been identified, analyzed and summarized under the headlineswinter-road, vegetation, road equipment and road designs.To elucidate the problem from several points of view, interviews wereimplemented with project leaders in investment and roaddesign engineers.

This thesis describes the process of developing a reservation system for common resources through a TV-interface.

The main goal was to develop a reservation system and to make it work with Dreamgallery, to develop a demonstration version of the system. The thesis describes the approach for developing an easy-to-use and customisable program and interface for making reservations. How this is inserted into an existing program in a suitable way.

The aim of this essay is to examine the relationship between picture and room, between wallpainting and architecture. The basis for such exploration is the mural painting in Sweden at the turn of the 20th century, and the artist in focus is Prince Eugen (1865-1947).His works "Sommar"(1904), "Rimfrosr"(1909) & "Staden vid vattnet"(1922) and the rooms in which they are in make for an anlysis concerning how the totality of the space is experienced by the viewer.The main issue in mentioned expeience is how the mural is perceived with regard to the other elements in the room. And here, the walls' "flatness" enhancing its decorative qualities plays in. The problem with a mural built on the principles of perspective becomes evident when a wall is seen to vanish through the painting of an illusion on it..

The foundation of our study is five strategically selected printed advertisements which all contains signs that refer to digital medias. Through a quality content analysis, we are studying how advertisers may use a room with extended communication too enlarge the space given in a printed advertisement. The potential in these rooms are proposing a social connection and a flexible interaction by providing content that is not possible to create in a printed advertisement. The form of communication is changing and there is a two-way communication created in an obvious way. The different kinds of roles in the communication process are here partially integrated with each other.

Climate and environmental issues is now high on the agenda. We live in a generation that must try to solve some major environmental problems. Buildings and habitations account for approximately 40 % of Sweden's total energy today. To reduce this figure, as needed, more research in the field of energy efficiency is required.This thesis concerns the heating of buildings. The load on district heating is heavy during certain times of the day.

This thesis of 15 hp has been implemented at Halmstad University, in collaboration with Saab Dynamics in Linköping. Saab Dynamics is a company operating in the defence industry where competition is tough. This necessitates new ways to increase efficiency in the company, which is the basis for this thesis. Saab Dynamics wants to introduce simulation driven design. Since Saab Dynamics engineers have little experience of simulation, required a user methodology with clear guidelines.
