Uppvärmd konstgräsplan : Beräkning av utnyttjningstid för en uppvärmd konstgräplan med alternativa rörplaceringar
For Skattkärr IF a turf field with warming has been projected to increase field?s utilization hours and to have a longer period for athletes to perform their activities outdoors. The technique chosen to heat the plan is a type of a geothermal heating system without a heat pump. The brine, which is water with 30% ethanol, collects heat from the borehole and discharges it to a coil in the field. There is at position 11 boreholes but it is planned to increase the number to 31, which is the design for the facility.

Tillgängliggörande Vs Distribution : Är en skiva en skiva om den enbart finns digitalt?
The aim of this essay is to examine if the Swedish Major labels are moving towards making their catalogue available on different platforms rather than their traditional distribution of music. The new technology has really stirred things up for the major labels and file-sharing has been a problem for a long time. The labels have a history of fighting new formats instead of embracing them and listen to what their consumers actually want. We have found that the majors now are in the leading edge of music distribution due to technology and that is a first. We have focused this essay on if the consumption of music has changed the distribution of it or the other way around and found that people have changed their ways of consuming music over the years and the labels have always been forced to adapt.
Riskpremier på den nordiska elmarknaden : En explorativ studie av riskpremien för Electricity Price Area Differentials (EPADs)
Uppsatsens explorativa syfte är att utforska samt beskriva riskpremiens storlek och utveckling för de EPADs som handlas för olika elprisområden på den nordiska elmarknaden. Riskpremien har definierats enligt de prissättningsteorier som ursprungligen formulerats av Fama & French (1987) och beräknats ur ett ex post-perspektiv. Studien omfattar drygt 700 EPAD-kontrakt från perioden 2006 till 2014Tillämpning av deskriptiv statistik visar existensen av betydande riskpremier vars tecken och storlek varierar mellan områden och tidsperioder. Detta är i linje med tidigare resultat av Kristiansen (2004) samt Marckhoff & Wimschulte (2009). Några långsiktiga trender har inte kunnat säkerställas statistiskt.
Hur fungerar egentligen ko?pbeslutsprocessen inom e-handel? : En kvalitativ studie om konsumenternas beteende vid konsumtion pa? Internet.
Title: How does the buying decision process really function within e-commerce? - A qualitative study of consumer behavior when they consume on Internet.Institution: School of Economics, Linnaeus University, Va?xjo?.Course code: 2FE16E.Authors: Sara Hja?rne, Mathilda Perem, Ewelina Wallin.Tutor: Dan Halvarsson.Examiner: A?sa Devine.Key words: Buying decision process, purchase decision process need recognition, information search, evaluation, purchase decision, postpurchase behavior, consumer decision making, E-commerce, E- commerce channels, online shopping, online purchase, e-retail, internet shopping, electronic shopping, consumer behavior, online appereal shopping, social media, decision making, online retailing, website design, customer satisfaction, webshopping, perceived risk, convinience, price, online consumption behavior.Background: Buying decision process is a model that marketers use to get a better understanding of their customers and their behavior when purchasing a product. This process consists of five different steps; need recognition, information search, evaluation of alternatives, purchase decision and evaluation. Buying decision process has for a long time been an accepted model but scientists argue that the introduction of Internet as a channel for consumption has changed this process. The Internet has also led to a change of power in which customers today have greater influence, which greatly affects the buying decision process in e-commercePurpose: The purpose is to explore how consumers perceive their behavior when they consume through e-commerce.Research questions:How do consumers perceive the buying decision process they experience when they consume through e-commerce?How do consumers perceive different factors that are important to them when they consume through e-commerce?Methodology: Qualitative study, cross-sectional design, semi-structured interviews.Conclusion: This thesis shows that the traditional model of the buying decision process is not consistent with consumers' perception of how they are undergoing the process when applied to an e-commerce context.
Klimatskärmens funktion : En jämförande analys av projekterade nybyggnationer i Östra Salabacke, ur ett energi- samt fuktperspektiv
The design of the building envelope affects the energy consumption of a building. As the energy requirements for new buildings are becoming more demanding, the performance of the building envelope must be improved. Energy efficiency and durability are important attributes to consider.This report includes investigations of the building envelope, moisture and passive solar energy. It is based on the analysis of two different buildings with different designs. These buildings stand as reference for two of the companies who are working on a new, climate smart, residential area in Uppsala, Sweden.Studies and analyses on energy consumption and moisture transportation were made.
Energi- och exergiflöden i stålframställningsprocesser vid
SSAB Tunnplåt AB i Luleå
Energy costs are high nowadays and that is the reason why the energy consumption needs to become as small as possible in most of the companies. To accomplish the small energy usage one needs to map the energy flows, study them and monitor them. One method that can be used for this is energy balance calculation. The method gives an opportunity to separate different energy flows and see where each flow is heading. There is also another method which is more advanced than energy balance calculation.
Optimering av driftläggningar i Fortums nät
Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.
Renovering av flerfamiljsbostäder inom miljonprogrammet ur ett energi- och lönsamhetsperspektiv
Miljonprogram is a Swedish building program from 1964 to 1975. During that time about a million homes were constructed. Now, almost 50 years later, they are in desperate need of renovation. In order to fulfil the Swedish environmental objective to decrease energy consumption 50 per cent until 2050, considerable housing stock built under the Miljonprogram has to be renovated.Focus in this thesis is on the building services and theirs profitability that can decrease energy consumption in households build during the Miljonprogram. Building construction is not considered in this report.
Investeringsbedömning av energieffektiva småhus i trä
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.
Man och kvinna till salu : En studie av manliga kontra kvinnliga modemagasins framställning av genus och konsumtion
Due to the developments in today's gender discussions, this essay aimed at investigating the gendered constructions and encouragements to consumption. As a former fashion student I have a special interest in the commercial constructions featured in fashion magazines, especially since advertising, fashion and perceptions of gender have long walked hand in hand. Just as feminism studies have shown femininity being a fluid identity, recent studies of masculinities, media and culture are also showing changes in the depictions of men.The aim was to clarify how fashion magazines encourage men and women to consume products and ideals, and also discuss the gender constructions occurring in the junction of editorial and commercial text (articles and advertisements). The analysis was thereof based on three main questions:- How is consumption encouraged in male and female fashion magazines?- What kind of gendered pattern appears in the junction of advertisement and editorial text?- With regard to the gender constructions, what is the reader encouraged to consume?The theoretical framework of the analysis was based on gender studies and political economy, mostly describing a commercial perception of feminine journalism and a new metrosexual expression in men?s fashion and lifestyle magazines.By using a combination of quantitative (content analysis) and qualitative (semiotics) approach two fashion magazines, Elle and King Magazine (published in May 2013) were used as representatives of fashion magazines in general.The results showed clear differences between the sexes.
Foderhäckar till hästar i lösdrift :
Knowledge about feed racks for feeding forages to horses is lacking. Racks for sheep and
cows are sometimes used for horses. Feeding roughage on the ground, or feeding silage bales
with the plastic and net still on, can bring on a lot of different problems. The opportunity to
control the hygienic quality is small and feed losses can be high.
The purpose of this experiment was to investigate how the eating behaviour and consumption
of horses were influenced by feeding racks of different constructions. Feed losses and changes
in chemical composition of the forage were also studied.

Energy from municipal solid waste in Chennai, India : a feasibility study
Solid waste management is one of the most essential functions in a country to achieve asustainable development. In India, it has been one of the least prioritized functions during thelast decades. The most common ways to treat waste in India today are open dumping anduncontrolled burning. These methods are causing severe environmental pollution and healthproblems. India is one of the world?s largest emitter of methane gas from waste disposal.Since methane is a strong greenhouse gas, even small emissions have large impact on theclimate.
