Hållbara transporter i Hemavan Tärnaby och Åre : En innehållsanalys av 13 Svenska turistaktörers hemsidor
Transport is an important aspect to take account in efforts to achieve sustainable tourism development. If we do not change our behavior regarding travel, the consequences will be significant for the environment. This study examines the various transport operators on the two Swedish ski resorts if their websites and marketing are different from each other in the mode selection. The destinations are Åre and Hemavan Tärnaby. They studied modes are two Swedish airlines, two train companies, three bus companies and three taxi companies.These corporate websites are studied with a content analysis in which the results of the keywords that have been developed are scored according to different categories.
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.
Vätgas och bränsleceller : Ny energi för Försvarsmakten?
The purpose of this paper is to identify the current status of fuel cell technology and to establish whether said technology is mature enough to be implemented into the Swedish Armed Forces. The question to be answered in this paper is as follows: Can hydrogen gas and fuel cells be used as an alternative source of energy within the Swedish Armed Forces?This paper is based on theoretical studies and reports from prior research done on fuel cells. By studying these facts a predictive answer has been obtained. The answer I have come to, is that the maturity of fuel cell technology is currently inadequate for the Swedish Armed Forces to implement, especially considering its harsh working conditions..
Jag är teknisk : Ett stöd i teknikundervisningen
Teknikämnet har, sedan det fick en egen kursplan, åsidosatts i skolorna. Deltagande observationer och intervjuer med lärare verksamma i varierade åldersgrupper, visade samma resultat gällande tankar kring teknikundervisningen som de uppfattningar som litteraturstudien visat. Det framgår att många lärare inte uppfattar sin ämneskompetens som tillräcklig och att de inte vet hur de ska förhålla sig till ämnet i undervisningen. Resultaten av dessa studier ligger till grund för ett läromedel, bestående av en elevbok och en lärarhandledning, som utgår både från Lpfö 98 och centrala innehållet för år 1-3 och 4-6 ur kursplanen i teknik i Lgr 11..
Studieval och yrkesval : En jämförande studie om elevers val på Teknikprogrammet respektive El- och energiprogrammet.
The purpose of this study is to understand the factors that are affecting students at the Technology and Electricity- and energy programs in their choice of studies and vocation. The study is a comparative case study and quantitative method has been used in the form of questionnaires. The result shows that students do not like to be affected by another person but believes that they themselves have made their choice. Interest turns out to be the biggest influence factor of choice for both students at the Technology and Electricity- and energy program. For Electricity- and energy students have also access to work had some impact.The parents' education level was higher for Technician students and their parents worked with occupations requiring university degrees.
Effektivisering av byggproduktion med VDC och förstärkt verklighet : Streamlining construction work with VDC and augmented reality
Virtual Design and Construction (VDC) is currently used more and more within construction design and planning as well as construction as a streamlining tool aiming to improve communication and decrease the number of construction defects. VDC is constantly developing, but what comes next? The augmented reality (AR) technology is currently not used within construction in Sweden but should be considered as the next step in line regarding the integration of reality and digital information. Using this technology design can become reality even before it?s actually built.The purpose of this study has been to carry out an inventory of the existing AR technology and its shortcomings, and also to identify possible applications within the construction phase.
På väg mot ett hållbart resande? : En fallstudie kring den lokala kollektivtrafiken i Umeå tätort
Sustainability and the traffics impact on the environment have become increasingly central within spatial planning. For many years, planning has been focusing on building new roads - this has resulted in increased use of automobiles, which many believe is unsustainable in the longer term. Therefore, authorities at national, regional and local level want to increase the use of alternative transport modes ? such as walking, cycling and traveling by bus.The thesis intends to study if the Municipality of Umeå?s policies for sustainable development have led to an increased use of public transportation. The use of public transport in Umeå is also compared with developments at national level, in order to see if there are differences in the level and trend.
Knapptryckardemokrati : Om synsätt på IT-stödd demokratiförnyelse
With the increased significance of information technology (IT) in today?s society the term ?electronic democracy? (e-democracy) has gained much importance within the democracy theory. Naturally, there are several competing views on how the technology should be used for democratic purpose. One aspect of this is the somewhat revitalized claim for direct democracy in accordance with the hypothetical opportunity to finally realize it as a democratic system. The ideal of direct democracy combined with the almost total credence in the potential of technology constitute the idea of a ?push-button democracy?.
Att ta cykeln till arbetet : en studie av Stockholms satsning på cykelpendlare i jämförelse med Köpenhamn och London
The bicycle is an individual means of transport. Many people prefer to cycle over short distances and in congested areas rather than take travel by car or public transport. This is a study of the use of bicycle as an option for commuting to work. It is a comparison between three cities: Stockholm, Copenhagen and London. The comparison is focused on solutions that benefit commuter cyclist and performed by studying cycle policies and other related documents.
Däck-mark Interaktion hos skogsmaskiner
The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.
Ledtidsreducering ur ett värdeflödes-perspektiv
This case study is performed within the production of Sherwin-Williams, Bellö. The purpose is to increase the understanding how a value stream can function more efficient, from a lead time perspective. With the analytical model that is build up on known theories, the purpose have been fulfilled. Mapping of value and non value time for four products thru their respectively process reveals wastes, which is, waiting, transport and movement, incorrect processing and set-up time that in it self create transport and movement. Thru identified wastes that causes loss in lead time suggestions of improvement has been proposed.
Styrning och nödbroms av ModuLith
The purpose of this project is to get a fully functional, automatic steering system and a variable breaking system with an emergency breaking function to an off road vehicle. This off road vehicle is supposed to work as an aid in military situations. A team of two, Sebastian Attervall and Nichlas Gustafsson, got an order from Jonas Nyårds and the PreeRunners Project to construct a steering system that could manoeuvre an off road vehicle without any human involvement. To make this possible the vehicle would be guided by onboard sensors, cameras and computers. The team where also assigned to construct an automatic breaking system, there also no human would be involved.
Förutsättningar att utforma stationsbatterier i vattenkraftverk med Li-jonteknik
In hydropower plants it is necessary to always have local power supply. Therefore, the plants are equipped with batteries as stationary back up power. Vattenfall Vattenkraft is using lead acid batteries but has been investigating alternatives to replace them. The aim of this study is to investigate the potential of using Li-ion technology as back up power.The study showed that Li-ion batteries have many qualities. The Li-ion technology will decrease the space and maintenance demand.
Implementering av Virtuellt Byggande i byggprocessen : Fallstudie av NCC Construction Sverige AB
Virtual Design and Construction (VDC) is the definition for using BIM in the construction process to simulate and analyse the building. Resulting use of the technology will according to proponents lead to fewer construction errors, a better understanding between stakeholders for the construction project, less communication problems and a smoother construction process. Although BIM has according to researchers a big potential, few companies have succeeded in broad and continues implementation. The study aims to identify the factors affecting the implementation. More precisely identify what factors influencing the decision to adopt VDC and potential barriers in the diffusion process. The empirical findings are based on a case study of NCC Construction Sweden.
CSR inom livsmedelsbranschen : Studie över ICA:s CSR-arbete inom transport av varor
Corporate Social Responsibility, ett företags samhällsansvar, har på senare år fått större plats i näringslivet. CSR bygger på idén att företag frivilligt redovisar vilket socialt, etiskt, miljömässigt och ekonomiskt ansvar de tar inför sina intressenter. En företagsbransch med daglig inverkan på världens samhälle är livsmedelsbranschen. Branschen har ett välutvecklat och komplext logistiksystem där transportverksamheten är en central funktion. Syftet med denna studie är att beskriva och utvärdera dagens CSR-arbete ur ett miljöperspektiv inom livsmedelsbranschens transportverksamhet.
