Miljöbilsanvändning : En attityd- och beteendeundersökning hos ägare av bilar drivna med förnybara drivmedel
The aim of this report is to give a picture of how attitudes and behaviours of owners of environment cars look like and how they can be influenced. The alignment lies on environmental cars which run on biogas and ethanol which both are renewable fuels. The starting point is to sort out if it is environmental thinking that controls the choice and use of an environmental car. The feeling is that there are many other factors that can be more controlling, for example the price and the quality of the car. The result of the questionnaire survey which is the foundation of the report shows however that those who buy an environmental car do it mostly because of environmental reasons.
Medias bild av incitamentsprogram - har publicerade artiklar en påverkan på aktiemarknaden?
This study examines how the stock prices are affected when articles, which negatively describe the companies? incentive programs, are published. According to the efficient market hypothesis, only new information should have an effect on the stock price. Furthermore, this study aims to examine whether this reaction is dependent of the economic climate. During the period of September 2005 to September 2009, stock price data was collected from the NasdaqOMX stock exchange and 75 articles were gathered from leading Swedish newspapers.
Korttidsregleringsmönster i Ångermanälvens avrinningsområde : Har elmarknadens avreglering påverkat regleringsintensiteten?
The effects of the deregulation of the electricity market 1996 in Sweden on short-term hydropower regulation are unknown. This report investigates patterns in subdaily regulation in the Ångerman River Basin during the period 1993-2011. Differences in subdaily flows and zero flow events between the periods 1993-1995 and 1996-2011 were studied by analyzing hourly data from 8 regulated and 8 unregulated locations with four subdaily flow variation indices. No correlations between the market deregulation and the regulation intensity in the Ångerman River basin were detected. The number of days natural ranges of variability were exceeded and the magnitude of subdaily variation were significantly higher at regulated locations.
Varmhållen och kyld skolmat : En jämförelse med fokus på energianvändning mot bakgrund av livsmedelssäkerhet och näringsretention
The aim of this report has been to investigate the use of electricity energy before and after a conversion of foodservice. The ambition was also to highlight the food safety and the retention of nutrients in relation to the conversion. The methods being used were qualitative interviews, case studies, study visits and literature. The equipment and the use of energy was the same in 2008 as in 2011 for hot-holding of the tested component, sauce with ham. The chilled system used more than three times the energy and cost for one portion than one portion in the hot-hold system.
Analys av mellanspänningsnätet i centrala delar av Västerås stad
The dependency of continuous electricity supply is high in the Swedish society today, at the same time no one is willing to pay for a too costly or over dimensioned power distribution system. The owners of the distribution systems are the ones responsible for this balance act of maintaining a high quality of electricity delivery to customers at a reasonable cost.In this master thesis a limited part of the primary distribution system (10 kV), owned by Mälarenergi Elnät AB and located in the city centre of Västerås, was chosen for a deeper analysis of its reliability. Its ability to handle outages of system components (N-1 and N-2 contingency analysis) was investigated to find out potential weak spots and parts of the grid that showed signs of being overdimensioned.The results of the performed simulations showed that in 74 % of the studied N-1 contingencies cases, consisting of outages of a bus bar in a distribution substation, the system could handle this without causing outages in other parts of the grid. For the N-2 contingencies 61 % passed the test. It was also found that one of the two included high voltage substations could alone supply the investigated part of the grid.
Återvinning av industriell restvärme som värdeskapande process : En fallstudie på SSAB EMEA i Borlänge
The industrial sector accounts for a large share of greenhouse gas emissions. To reduce its negative impact on the environment is crucial in the quest for a sustainable future. In discussions of the industrial sector's impact on the environment guidelines have been highlighted as a tool to assist the industries in their efforts to change the relationship between the consumption of energy and production. This by improving energy efficiency and a shift to the best available technology. During the past 30 years the steel industry has reduced its energy consumption per ton of steel produced by 50 percent.
Smarta lokala energisystem, Vision-Teknik-Tillämpning
The energy sector is facing an impending paradigm shift. Today?s technology enables the end-user to generate their own energy locally at home. Furthermore, recently developed storage technologies make it possible to balance energy demand with stored energy and integrate district heating with the local power grid. This means that in the future heat and electric power will interact and energy flows is converted over energy boundaries.
Hur återförsäljare kan arbeta med sitt varumärke : En fallstudie bland klädåterförsäljare i Halmstad
The study has shown that retailers in the mid-price segment differentiate their brand through developing a strong company identity around the brand. The personality involves store atmosphere, merchandise and advertising. Larger companies have chosen to lay the responsibility on management level, which facilitates on store level. By controlling the strategies on a central level the company can make sure that the stores are steered in the direction that the company wants them to be steered in, and also that they follow the positioning-concept. The company can also devote its efforts to working with its core value, which is service.
ITP - Market Entry Strategy
Forces of innovation alter the course of many industries. Currently there is a restructuring of the Swedish energy sector due to deregulation. This in combination with advanced technologies generates an innovative and a highly changeable environment. The result is differentiation of services and products. New actors are emerging and corporations grow larger.
Biogas till kraftvärme på Wapnö : en projektanalys utifrån ett företagsekonomiskt perspektiv
Biogas is a gaseous fuel, rich in methane, produced through a biological route in an anaerobic digester. A gas engine generates combined heat and power, which can be used at the farm to reduce energy cost. The process also generates a digestate, with better utilization of nutrient compared to cattle manure.
The aim of this study is to analyze the profitability of a farm-scale biogas plant for combined heat and power (CHP) at Wapnö. Wapnö is an agriculture company located in the southern part of Sweden.

Studien visar att det bara förekommer ett långsiktigt samband mellan oljepriset och ett fåtal av aktieindexen. Nyckelord: Olja, Kointegration, Tidsserier, Aktieindex Abstract This Study investigates if a long-term relationship between oil price and selected stock indices can be proved.
Nyckelfaktorer vid exportetableringar i Tyskland : - En studie gjord på fyra norrländska företag
A common assumption in marketing is the wider variety of product a corporation has, the better for the consumer: more product - more choices. Companies often develop a line extension to broaden consumer range through product attributes including quality, function and design. These developed attributes within the product are not always optimal for the consumer. As a result, companies often become entangled in having a price higher than the cost and benefit of the products. This essay aims to analyze the consumer value of line extension products and how these evaluations relate to extended line product pricing.
Potential för värmeåtervinning från mjölkkylanläggningar
The present climate discussion has made energy efficiency an interesting topic. Saving energy does
not only help the climate but also saves money for the energy consumer.
The purpose of this thesis was to examine the potential of heat recovering from milk cooling. Two
milk farms, one with voluntary milking system, VMS, and the other with conventional milking system
was used to measure interesting temperatures and electricity consumptions. The numbers were used
both to do theoretical calculations and to construct a SIMULINK model.
To calculate the potential for heat at milk farms theoretical calculations were made in MATLAB using
a reference farm with different combinations of heat recovery and pre cooling. The farm was
assumed to keep a dwelling house with the annual heat consumption 18165 kWh.
Environmental impact assessment of energy recovery from food waste in Singapore : comparing biogas production to incineration
As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.
Verkligt värde i praktiken : En studie av tillförlitligheten vid fastighetsvärdering till verkligt värde
The ongoing harmonization process aims to incorporate IFRS regulations into the Swedish accounting. As a consequence investment property?s starting from 2005 may be valued using the fair value method, in accordance to IAS 40. This involves major changes for listed property enterprises that from now on can value a large extent of their assets to fair value. All parties don?t appreciate this progress, opponents to fair value have expressed great concern that fair value don?t work in practice.
