Competition for forest fuels in Sweden : exploring the possibilities of modeling forest fuel markets in a regional partial equilibrium framework

This thesis project focuses on the need for better tools for analyzing competition for forest fuels in Sweden, in particular how policy measures may influence the market and involved actors in different regions of Sweden. Raw materials from the forest have for long constituted important inputs in the Swedish forest industry. Today some of these raw materials are increasingly used as inputs also in bioenergy production, largely driven by bioenergy promoting policies, and there are signs of increased competition for forest fuels which may have various and uncertain effects on the industries in question. The thesis project explores the possibilities to adapt previously used forest sector equilibrium models into a new model suitable for analysis of Swedish forest fuel markets, called the Swedish Forest Sector Trade Model (SFSTM). The approach takes into account regional differences in supply and demand for 23 types of products produced and/or used by eight types of producers, plus consumers, in five different regions (four Swedish and one international).

Beslutsunderlag för energianpassade gallringar i Västerbotten

The demand for renewable energy is increasing in Sweden. This consequently increases the pressure for and willingness to pay for forest fuels. One method to extract forest fuel from suitable commercial thinnings is the "long top method? (LT-method). With this method saw logs and non-delimbed tops are recovered, i.e.

Energieffektivisering och beslutsfattande inom fastighetsbranschen : En studie av hur ett energibolag kan bistå fastighetsägare

I Sverige står byggnader för nästan 40 procent av den totala energiförbrukningen och energibesparingspotentialen är enorm. Samtidigt dyker det upp mängder med aktörer som vill hjälpa fastighetsägare att energieffektivisera och allt fler energitjänster introduceras till marknaden. Möjligheterna för ett samarbete mellan fastighetsbolag och företag som erbjuder energitjänster har aldrig varit större, och en av dessa aktörer är energibolagen. Konkurrensen är dock hård och för att säkerställa sin konkurrenskraft på marknaden krävs effektiva samarbeten, där kundnöjdhet är i fokus, vilket i sin tur ökar behovet av kundkännedom hos energibolagen.Syftet med denna studie är att hjälpa energibolaget Elkraft Sverige att förstå olika fastighetsbolags energisituation och behov av energitjänster, samt rekommendera hur de bör utveckla sitt energitjänsteerbjudande för att kunna bistå dessa kunder på bästa sätt i framtiden.Detta gjordes genom att olika typer av svenska fastighetsbolag kartlades och analyserades med avseende på deras energisituation, beslutsfattande gällande energifrågor samt behov av energitjänster. För att samla in data genomfördes först en litteraturstudie, sedan semi-strukturerade intervjuer med högt uppsatta beslutsfattare samt en enkätundersökning.Slutsatsen blev att Elkraft Sverige bör finslipa sina befintliga energitjänster och komplettera sitt begränsade erbjudande genom att ingå externa allianser med kompetenta aktörer.

Egenproducerad solel i ett småhusområde

Sverige ska år 2020 ha en energiförsörjning bestående av 50 % förnybara energikällor. Den viktigaste källan till förnybar energi är solen. Solel är dock en dyr investering idag och gällande regelverk försvårar möjligheterna till att tillgodoräkna sig egenproducerad el.Byggföretaget JM bygger redan hus med låg energianvändning. Ett sätt att bidra till ett förnybart energianvändande är att installera system som producerar egen el till husen. Detta arbete har genomförts för att undersöka om solel kan komma att bli en konkurrenskraftig produkt att erbjuda JM:s husköpare.

Nyttjanderätt till fast egendom - Hyra eller arrende?

Uppsatsen behandlar olika definitioner av korruption utifrån internationella regelverk. The United Nations Convention against Corruption (UNCAC) ger en mer specifik definition till korruption än the African Convention on Combating and Preventing Corruption and Related Offences (AUCPCC). Då det finns flera olika definitioner av korruption kan diskuteras huruvida en enhetlig definition är nödvändig. Korruption påverkar även rätten till att bli prövad av en självständig och oberoende domstol. De internationella regelverk som behandlar denna rättighet är the Universal Declaration on Human Rights (UDHR), the African Charter on Human and Peoples? Rights (ACHPR) och the International Covenant on Civil and Political Rights (ICCPR).

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..

Finansiella värderingsmodeller : En empirisk studie

This study tests two financial valuation models empirically by valuing three stocks from three industries, with the purpose of studying how well valuation models work empirically and to make a forecast. The models which will be tested are residual income valuation and discounted cash flow. Nine stocks will be picked strategically from the Swedish stock market and additional analysis will follow in the analysis chapter.Based on analysis and valuation, the commodities industry has decent valuation as the healthcare industry is undervalued thanks to the high valuation of AZN. The energy industry has low value due to the capital intensive nature of the industry. When it comes to the models and their practical implementation, DCF has been the most problematic to apply empirically whereas RIV was better but it still shows extreme values, which teaches the student the clear difference between theory and empiri..

USA:s syn på Turkiet, från 1997 fram till våren 2007

The aim of this essay is to analyze the political interests of the United States Government in Turkey, from 1997 to spring 2007, using a qualitative method. I will also analyze any strategic changes during this period, by using theories of realism, particularly Structure Realism and Rational Choice. Using the Rational Actor Model (RAM), I will analyze how nation states such as the United States act in the political arena in Turkey. How can the US Government legitimize the support to Turkey and at the same time criticize there democratic deficit and their view on human rights. Turkey has been an American Military Ally, via NATO since 1952 and its demographic situation has changed since the Cold War.

Avsättningsmöjligheter för slaggrus från avfallsförbränning vid Åmotfors Energi

The incineration of waste is steadily increasing in Sweden and so is the production ofashes. The bottom ash has for many years been used as construction material inlandfills. Now many of the nation's landfills are closed and there is a great need to findanother beneficial use for the ash. Bottom ash is a gravel-like material and with itsmaterial properties it can replace natural gravel in parts of roads and surfaceconstructions. Today this use is only approved within landfill areas where leachate iscollected and checked.

Avloppsvattenbehandling med membranbioreaktor : En jämförande systemanalys avseende exergi, miljöpåverkan samt återföring av närsalter

In the pilot plant at Hammarby Sjöstad, Sjöstadsverket, several new methods are tested in order to achieve a good use of resources. When a new technique is considered it is often the performance of the technique itself, under given conditions, that is evaluated. However, in order to evaluate the overall function the whole picture is needed. With a system analysis it becomes possible to make a comparison where all the positive aspects are put up against the negative ones, for the technique itself as well as its requirements. In this way the influence that minor components have on an entire system can be considered.This report presents a system analysis of an anaerobic membrane reactor (MBR) with a VSEP-membrane (Vibratory Shear Enhanced Process).

Termisk energilagring i borrhål : En studie av borrhålets temperaturinverkan på värmepumpens värmefaktor

Sverige har en hög andel installerade bergvärmepumpar, som är en typ av vätska-vatten värmepump. Ett problem som finns för befintliga bergvärmesystem är att berget med tiden kyls ned då returslangen till borrhålet konstant levererar kyla till berget. Till följd av detta mister systemet en betydande del av sin verkningsgrad samtidigt som det i extrema fall kan leda till permanent isbildning i borrhålet.Ett sätt att motverka detta problem är att tillämpa termisk energilagring i bergvärmesystemets borrhål. Den internationella benämningen för denna teknik är ?Borehole Thermal Energy Storage, BTES?.Rapporten har behandlat en friliggande enplansvilla med ett befintligt bergvärmesystem som tillämpar termisk energilagring i bergvärmesystemets borrhål med solvärme.

"Målsättningen är en nöjd värmlänning" : Vårdpersonalens syn på tillgänglighet, bemötande och kvalitet i patientmötet

We have made a qualitative study where we have chosen to interview a number of respondents consisting of ophthalmologists, eye nurses and patients. The purpose of the study was to examine employees' perceptions of patient-related status and treatment and quality, and meaningful participation in the work. The conducted interviews, we then sat in relation to how patients experienced the visit to the eye clinic and their perception of accessibility and hospitality. The result is then compared against the policy of the Title use of internally and we have also tried to explain what is happening with the help of various theorists. Theorist that we made use of is Maslow, Foucault, Deming (TQM) and Herzberg.

En studie av sex ISA-system

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.

Hur påverkar en ökad andel solceller Umeå Energis elnät? : ? En utredning med fokus på spänningsvariationer och osymmetri inom landsbygds- och tätortsnät vid en- och trefasanslutning av solcellsanläggningar

A good power quality can be an important prerequisite to achieve a sustainable society. Scandinavia's electrical system is in many respects superior, and Sweden has a fossil free electricity generation at 97 % and a reliability of electricity distribution at 99.98 %. Meanwhile, the EU has an ambition to expand the electricity market in order to achieve a joint trading business across Europe. This cross-border market will result in a large proportion of fossil energy sources integrated into our electrical system, which also leads to an increased need for renewable electricity production in Sweden. One part of this development is to increase the share of renewable micro generation that is locally or regionally connected to the power grid.
