Kunders betalningsvilja- från initialkostnad till drift- och underhållskostnad

Many interactive products constructed today is not produced towards a specific targetaudience and how they will interact with the product. This master's thesis follows the designprocess in the development of the Let's Walk webapplication. In the designprocess has users of the webapplikation been identified, prototypes developed and an interactive version has been evaluated. The Let's Walk webapplication is a fully working system used to administrate Let's Walk, an exercise competition between companies. Experts and users have been involved to evaluate the Let's walk high-fidelity webapplication prototype.

Alternativa dagvattenlösningar för nyexploateringsområden med avseende på substansflöden

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

?Ett fantastiskt redskap!? En studie om hur personer i åldern 65 ? 75 år använder och upplever Internet i sin vardag

The main purpose of this master thesis is to investigate how six elderly individuals, 65-75 years old, use and perceive Internet in their everyday life. The focus in this study is to enlighten elderly people as Internet-users.In 2010 many elderly people are still digital excluded. In Europe and in Sweden efforts are made to educate citizens to use the Internet, and that benefits of the digital society should be available to all.This study is based on the following questions: what made the informants take an interest in the Internet in the first place? How and for what purpose do they use it? And how do the informants regard to their own Internet usage and its importance in society?We interviewed six people aged 65-75 years old, using semi-structured questions. The data was analyzed by using the theory developed by Hektor concerning Internet and information behaviour in everyday life.

Finns det möjlighet till arbitrage på VINX30 aktieindexoptioner? : en empirisk undersökning

Optioner är ett instrument som investerare kan använda för att spekulera i framtida upp-eller nedgångar på olika tillgångar. Om dessa optioner är felprissatta finns det möjlighet att göra riskfria vinster med hjälp av Stolls köp-säljparitet. Tidigare studier visar att marknaden inte alltid är effektiv i sin prissättning av aktieindexoptioner och att det därigenom finns möjlighet till arbitrage. Denna studie undersöker huruvida marknaden är effektiv i sin prissättning av VINX30 aktieindexoptioner, d.v.s. finns det möjlighet till arbitrag på VINX30 aktieindexoptioner?.

Konsumenters kunskap och uppfattning om nyckelhålsmärkta produkter

Syftet med studien är att klargöra om nyckelhålsmärkningen har betydelse för konsumentens uppfattning och val av produkt, samt belysa förekomsten av källkritiskt tänkande kring nyckelhålsmärkningen. Som metod tillämpades intervjuer på 50 respondenter. Studien indikerar att nyckelhålsmärkningen har en inverkan på både val av produkt samt den generella uppfattningen om hur hälsosam en produkt är. Studien visar även på en slående avsaknad av källkritik då konsumenter utvärderar nyckelhålsprodukter..

Temperaturförhållande och fluidsammansättning vid metamorfos registrerat i karbonatbergarter på nordöstra Utö

The concept of sustainable development is a challenge that demands cooperation from all levels of society for it to be successful. The focus for this thesis is how politicians within the local councils understand the concept of sustainable development and how they implement it in political decision-making.The basis for the study is a questionnaire that was distributed to 303 local politicians in three municipalities of varying size in Southern Sweden. The study concentrates on departments within the local councils that are directly connected to the Swedish environmental law and the Swedish planning and construction law. One of the primary goals with the aforementioned laws is the achievement of sustainable development within one generation.The outcome of the study was that over half of the local politicians could correctly define sustainable development according to the World Commission on Environment and Development?s (WCED) definition.

Samhällskunskapsämnet över tid : En undersökning mellan läroplan och läromedel från 1962 och 2011 i ämnet samhällskunskap

This essay is from a student at the cultural science program in Karlstad University. The essay in Culture studies deals about the history use and about the cultural-historical values on buildings. The buildings are from a certain area called the neighborhood Almen and have in the past been threatening many times of demolition. The neighborhood Almen buildings survived a huge city fire back in the 19th century. Since then the buildings has been known as a memory and by the inhabitants and as the oldest part of the city left.

Energieffektivisering av Villor : Finns möjligheten till Passivhusstandard för befintliga bostäder

The climate change the earth today has to face is no longer a global problem when every individual has a responsibility to act. The residents in Sweden have no understanding how their energy consumption affects the environment, nor what measures can be taken to reduce the energy consumption.The use of the energy in new Buildings is considerably lower than in the older ones as conditions have improved and the requirements have been more stringent. As most of the buildings in the future have already been constructed it´s important to take every opportunity for energy efficiency and rebuilding of available buildings will become a significant act. Reconstruction of a building contributes generally to both a reduced individual and a reduced total energy use, while new constructions only keep a low individual energy use but a increase the total energy use. For this reason we present the opportunities for reconstruction, mainly to reach the standards for a passive house..

En energiutredning och miljöklassning av Hemsta 12:16

The purpose of this study was to implement an energy analysis and environmental evaluation of the property Hemsta 12:16 in Gävle. Based on two different methods, Energy Balance calculation and Environmental Building, the result of the property's energy use, energy performance and environmental impacts are presented. Except that, measures to reduce final energy consumption are presented.      The proposed measures can reduce energy usage by 100 400 kWh / year, which represents a decrease of 18% of the present energy usage. This would represent a total savings of 63 000 SEK per year. In addition, the environmental performance is improved by adopting the suggested measures..

Låna Dig Rik : om en marknadsföringskampanj för folkbiblioteken i tre regioner och dess mottagande i lokalpressen

The marketing campaign ?Låna dig rik? [Get rich by lending] involved 25 public libraries in three regions; Kronoberg, Kalmar and Blekinge. This paper examines 28 news-articles concerning this campaign, found in eight publications in the responding regions. The purpose of this is to determine to what extent the description of the campaign found therein responded to the intents of its founders and to what extent the public had a say in these articles. The result found indicates that the overall image of the campaign presented in the news-articles was well in correspondence with the intents of the campaign itself but that the public views where arguably absent..

Ökad användning av biodrivmedel i vägtransportsektorn : en styrmedelsanalys

The Swedish road transport sector relies almost completely on fossil fuels. In 2007, as much as 96 percent of the total sales of fuels was made up of petrol and diesel, while at the same time the share of total emissions of greenhouse gases in Sweden that came from road transports amounted to close to 30 per cent. Sweden is by no means worse off than any other European country in these respects. In order to address the questions of high oil dependence and CO2 emissions the European Commission has proposed a reinforcement of the legislative framework, with a 10 percent minimum for the market share of biofuels in 2020. Furthermore, the proposed target is binding for the member states, unlike the current voluntary target of 5.75 percent by 2010. More than doubling the usage of biofuels in only a bit more than a decade will most likely not be possible without policy interventions.

Att motivera med belöning : En studie av attityder och beteenden på ett företag i hemelektronikbranschen

The underlying question addressed in this paper is whether or not it is possible to influence the way a company?s employees behave using monetary incentives. How efficient is money as a means to enhance work motivation? Today, the assumption that employees perform better when bribed with rewards is questioned by scholars. The previous confidence in monetary reward systems is increasingly being replaced with hope for more effective programs, where employees to a greater extent can be motivated by non-monetary incentives.

How do intrinsic and extrinsic motivation correlate with each other in open source software development?

Open source is growing outside the boundaries of hackers, amateurs and software development, creating a humongous potential in many different areas and aspects of society. The intrinsic and extrinsic motivations that drives open source have been in the subject of much research recently, but how they affect each other when paid and unpaid contributors come together is still hidden in obscurity. In this study I investigate how intrinsic and extrinsic motivation correlates with each other and how those correlations affect paid and unpaid open source software contributors. The literature synthesis is based on of systematic reviews through searches in library databases, identification of articles by searching on the Internet and by reading relevant books. My results indicate that intrinsic and extrinsic motivations continuously affect each other and that paid contributors are more vulnerable since their extrinsic motivation in terms of money is reached only when many other motivations are fulfilled.

Förebyggande Brounderhåll

AbstractThe Swedish Road Administration in the region of Mälardalen has since 2004 worked to in¬crease the efficiency of the maintance of bridges based on limited functional requirements and time demanded action.The maintenance of the bridges is contracted in the county of Uppsala since 2004, and Örebro since 2007. The county of Nyköping and Västerås is contracted by the traditional system. The contractor will perform a regular maintenance on all bridges. The bridges are inspected by the contractor at least once every year.The contractor registers the result of the inspection in a database called BaTMan. BaTMan is a Bridge and Tunnel Management system and is a strictly web solution were the user logs in via the internet.The Swedish Road Administration also inspects the bridges to se that the demands on the bridges are followed.My work is to compare these different inspections and to see any development..

Behandling av sommareksem hos häst med cetirizin : ett fältförsök

In this study we intend to evaluate the effect of cetirizin, orally administrated to horses with insect dermal hypersensitivity. The study comprised 156 horses from 49 farms, which were located in different parts of Sweden. The horses were matched on the farms and were given cetirizin or placebo in a double blind test. Veterinarians collected a blood sample and examined the horses visually, before and after three weeks of treatment and filled in given forms. The results are based on the veterinarians? subjective evaluation of the clinical appearance of the allergic dermatitis before and after treatment.
