District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

The purpose of this thesis work is to create a prototype for an augmented reality application that isaimed to support service technician when performing service and maintenance of machines andengines. The prototype will be used for investigating what technical limitations there is and toestablish basic usability for the user interface. The method that is used is user studies and analysis toevaluate use cases and user stories. An Iterative work process is then applied for design and theprototype is continuously user tested.The resulting prototype uses a Samsung Galaxy Tab 2 running on Android operating system. Theframework used for augmented reality is NyARToolkit which handles marker recognition andconnections to Android.

Every plan and program decided on by an authority or municipality, where the environmental impact can be considerable, must be environmentally assessed according to Environmental Code, the Planning and Building Act (PBA) and the Regulation on Environmental Impact Assessment.The purpose of this study is to examine the Environmental Impact Assessment (EIA) for The Region Development Plan for the Stockholm Region, RUFS 2010. The plan was approved by at that time the Regional Planning Office (Regionplanekontoret), which procured the process by consultants. RUFS 2010 includes two merged plans ie. a regional Development Plan (RUP) and the Regional Spatial Plan for Stockholm. It was necessary to establish an environmental assessment of RUP, but not for the regional plan.

Hemsidan är den enskilt största kommunikationskanalen mellan Ericsson och potentiellt framtida anställda. Företaget har idag problem med att den globala karriärhemsidan inte uppfattas som användarvänlig av särskilt studenter, och detta examensarbete syftar till att definiera krav för hur en global karriärhemsida bör utformas för att vara användarvänlig och välkomnande för studenter.Med en användarcentrerad designstrategi och en teoretisk bas inom interaktionsdesign och human factor syftar avhandlingen till att förstå vad studenterna efterfrågar och hur Ericsson kan möta och överträffa dessa förväntningar. Tester, workshops, utvärderingar och intervjuer har använts för att iterativt utveckla en prototyp och kravspecifikation.Studien visar att det finns två huvudsakliga typer av användare att designa för: de med ett tydligt mål att hitta ett jobb och de som försöker ta reda på om företaget är av intresse. Vanliga känslor hos användarna att ta hänsyn till ärångest, ensamhet, beslutsamhet, spänning och glädje. Några av slutsatserna kring den befintliga karriärhemsidan är att den vänstra menyn inte är organiserad på ett sätt som hjälper användaren att hitta vad han/hon letar efter, innehållet i mitten är för allmän och tråkig för många användare och högerspalten används sällan, trots att den innehåller vissa användbara funktioner.

Ett affärskoncept har tagits fram och resulterat i en marknadsplats. Marknadsplatsen är en webbsida och mobil applikation vars syfte är att skapa värde av resursers bokningsbara tider som idag har generellt låg beläggning hos aktivitetsanläggningar inom sport, kultur och nöje.Marknadsplatsen är tänkt att samla ett brett utbud av lågbeläggningstider inom olika aktivitetstyper som är typiska vardagsaktiviteter som vänner gör tillsammans. Tanken är att bygga ett starkt varumärke för marknadsplatsen med det tydliga budskapet att "marknadsplatsen tillhandahåller ett brett utbud av prisvärda erbjudanden inom sport- och nöjesaktiviteter, om du väljer att anpassa ditt schema utifrån anläggningarnas lågbeläggningstider". Dessutom är det tänkt att marknadsplatsen ska ha funktionalitet som gör det enklare för användare att boka en tid via marknadsplatsen, genom att synkronisera de olika alternativ av aktiviteter och tider som personer inom en grupp av vänner är intresserade av. Marknadsplatsen är tänkt att riktas till målgrupper med personer som har flexibla scheman, framförallt egenföretagare, studenter och pensionärer.

Thesis purpose: The purpose of this master thesis is to investigate the expectations of roles between supplier sales representatives and retailer store personnel in relation to in-store campaigns, this in order to enhance effectiveness of these functions creating an increase in consumer response. Methodology: The researchers believe that social phenomenon and their meanings are continually being accomplished by social actors, hence a study of individuals? expectations must have a point of departure in these people?s social reality. Store personnel and supplier sales representatives are to a certain degree affected by the structural power relationships within the organizational network, thus the researchers combine an interpretative and radical structuralist paradigm. Theoretical perspective: The researchers investigate expectations of roles through examining interaction between parties involved.

Provbanken är en del i ett nationellt provsystem som är tänkt att vara ett bedömningskomplement till existerande prov i gymnasieutbildningen. Växjö universitet har varit delaktig i utvecklingen av prov för de yrkesinriktade ämnena sedan 1997. Eftersom innehållet i dessa numera webbanpassade prov är det väsentliga, måste utformningen av provet göras lättförståelig. Användbarheten måste m a o vara självklar och inte ställa till problem för användaren. Som en av utvecklarna av dessa interaktiva prov, ville jag finna ett sätt att minimera problemen och öka användbarheten.

The project concerns a predevelopment work for Scania AB, a leading manufacturer of heavytrucks, and was performed as a master thesis work for the program Design and ProductDevelopment at KTH. The purpose of this work was to examine how the work situation of truckdrivers, especially long-haulage drivers, can be improved with respect to prolonged sedentaryoccupation. Mental fatigue and under-stimulation due to low cognitive load during long drivescan be major risk factors for traffic accidents. Physical strain injuries to both the skeleton andmuscles are common for this working group and minimal opportunity for daily exercise alsoincreases the risk of developing blood clots in the legs, which can have serious consequences forthe driver's health.An extensive background study, both theoretical and exploratory, was performed to identify thedrivers' concerns and comfort needs. Various treatments such as massage and active sitting wereinvestigated and existing products within the area studied.

Abstract Title: Ethanol for Scania?s future ? A scenario based analysis Authors: Anna Hansson and Julia Persson Tutors: Annette Cerne ? Department of Business Administration, Lund University Jonas Holmborn ? Head of Advanced Combustion, Engine Development, Scania Lennart Thörnqvist ? Department of Energy Sciences, Faculty of Engineering, Lund University Problem: Oil-based products are the dominating fuels in the transport sector but alternative fuels are currently challenging the world-wide dominance. The large number of alternative fuels that are under development at present makes the future fuel-market impossible to predict. Scania?s ethanol project is associated with a number of uncertainty factors that are beyond the company?s control.

The purpose of this paper is to examine how seams in an interactive system should be managed. Seamsin this study refer to the boundaries that arise when users move between for example differentsoftware, products or positioning systems. These seams are a cornerstone of the relatively unexploredarea called seamful design, which is based on that users can avail highlighted seams through activeparticipation in the use of a system. To analyze this area, seamful design is applied to the developmentof an interface of a smoothie vending machine. This smoothie machine thus provides the analyzedinteractive system, which the research questions are applied to as well as answered by.

AbstractAt the UN Conference on Environment and Development in 1992 the nations stated that traditional environmental policies were not sufficient to handle the multidimensional challenges posed by sustainable development. Governments needed to broaden their political decision making procedures in order to coordinate and integrate environmental, social and economic policies. Therefore a new tool was introduced in Agenda 21, National Strategies for Sustainable Development (NSDS). The aim of an NSDS would be to bring together actors from all parts of society to jointly reach a consensus on how to work towards the vision of a sustainable society. An NSDS would be seen as a strategic tool to help focus national policies for SD.
