En kostnadsanalys av energieffektiva flerbostadshus
In Sweden the real estate sector accounts for 33 % of energy consumption and just below 10 % of the emission of carbon dioxide. As a consequence of the external pressure from climate change it?s in everybody?s interest to reduce the energy consumption and thus reduce the emission of carbon dioxide. An additional incentive to reduce the energy consumption is the substantial increase of the energy price since the deregulation of the electricity market in 1996.In this study the techniques that exist to build multi-storey residential buildings with high energy performance will be investigated. Further the study intends to investigate the optimal energy performance from a real estate economic perspective.In order to investigate the optimal energy performance a model has been created with the parameters investment cost, rental revenues, operation and maintenance cost, discount rate and investment horizon.The result shows a relationship between a high investment cost and a high energy performance for newly constructed multi-storey residential buildings.
Analys av linjetaxering i samband med gallringsinventering med avseende på kvalitet, tillförlitlighet och framtida utformning
Modern forest owners are very familiar with forest management and forest economics. Therefore they have high demands for quality in forest operations. Guarantee of quality in the shape of self-checking activities is an important tool to guarantee a well managed forestry operation. To meet the forest owners? demands on guarantee of quality and the entrepreneurs wish of an easy method for self-checking, the forest owners association, Södra skogsägarna, has developed a new method for thinning inventory.
The purpose of this study is to evaluate the method that is used for self-checking and to find ways to develop and improve of the method.
The data has been collected by inventory in a number of stands with circle-area survey and with strip survey, which is method that is used for self-checking.
The results show that the strip survey does not diverge more than ±10 % in measuring values of basal area, number of stems, roads share, thinning quotient, outtake of basal area and total volume compared to circle-area survey.
Productivity of Norway spruce (Picea abies) and Scots pine (Pinus sylvestris) in coastal areas of northern Sweden
Productivity of Norway spruce (Picea abies) and Scots pine (Pinus sylvestris) was
studied on 12 sites in coastal areas of northern Sweden. On each site, sample
plots were placed in adjacent Norway spruce and Scots pine stands with similar
ages in between. Basal area, tree height, Site Index, volume production,
simulated maximum mean annual increment (MAImax) and tree vitality were
compared for the two species. Average basal area at the time of measurement
was 30.4% larger for Scots pine stands than for Norway spruce stands. The
difference between the two species in basal area increment during the last 10
years was related to stand age.

I kunskapsläget finns tre centrala begrepp presenterade, organisation, bestående beteendeförändring och ungdomsgrupp, vilka är relevanta för såväl syftet som frågeställningarna.Utifrån studiens syfte valdes en kvalitativ forskningsansats för att förstå varje intervjupersons livsvärld och framställa mening sett från dennes perspektiv och erfarenheter.
Aktiv ventilstyrning
To achieve an optimal combustion, an even air/fuel ratio in the combustion chamber is required. An optimal combustion leads to reduced amount of emissions due to a more complete combustion, which is an important matter because of the sharpened environmental laws. This can be attained, among other things, by applying entirely variable cam times. To optimize the engines efficiency and its emissions at all workloads and speeds, an active valve control can be applied. This means that the intake and exhaust-valves can be opened and closed at any time, independent of the crankshaft position.

Fire impact in the wood quality and a fertilization experiment in Eucalyptus plantations in Guangxi, southern China
Chinas government has a multifunctional program for a more sustainable forestry since 2000. This six key forest programs goal is to develop a more sustainable forest sector but also take environment consideration. The state forest administration in China has decided to create 5.8 million hectare of fast growing and high yield forest. Eucalyptus has showed to have good properties for pulp and timber production and therefore Eucalyptus plantations are under development in costal areas in southern China. By adding extra nutrients, growth can be enhanced in Eucalyptus plantations.
Patienter och sjuksköterskors upplevelser av palliativ vård
Människor har genom tiderna tagit hand om sina släktingar, vid sjukdom och i
livets slutskede, det som idag kallas för palliativ vård. För att den
palliativa vården ska bli så bra som möjligt för patienten krävs det att
sjuksköterskan har ett professionellt förhållningssätt, detta innebär att
hon/han har en helhetskompetens för att kunna bemöta patienten. Syftet med
studien var att undersöka patienter och sjuksköterskors upplevelser av
palliativ vård. Den valda metoden var en litteraturstudie där åtta artiklar med
kvalitativ ansats har analyserats. I resultatet framkom det att patienterna
upplevde att en optimal palliativ vård var en vård där någon tog sig tid att
lyssna och vara hos patienten.
Skattning av den integrerade hydrauliska konduktivitetens variation kring Tunåsens infiltrationsanläggning : En utredning av påverkan från möjliga osäkerheter i befintlig information
Estimation of the variation in the integrated hydraulic conductivity around the Tunåsen infiltration facility - An investigation of the effects of uncertainties in existing informationAlmost half of Sweden?s drinking water volume is produced from groundwater. The main fraction of this is extracted from eskers, some of which allow for very large extraction rates. Despite this, the groundwater volume is not sufficient in some areas. This has led to an extensive use of artificial recharge.In Uppsala, the total volume added through artificial recharge is divided between four infiltration facilities.
En jämförelse mellan två datorprogram för utbytesberäkningar :
This thesis is made on behalf of SCA's Forestry Division and is a comparison of two bucking simulation tools: Aptan (manufactured by Skogforsk) and Best/upr (from Berget Systemdesign). The data is based on 32 stands from SCA's forests in Norrbotten and Västerbotten. The objective is to compare the simulations created by the tools with the harvested volumes from those stands. Three variables are needed for the bucking simulation; these are the diameter distribution (at breast height), the relationship function between diameter and height, and the taper coefficients. The volumes of five different assortments from the stands are compared.
Ska åkerier leasa eller köpa? : Optimal kapitalstruktur för företag med stora investeringar
This study deals with the road freight sector's capital structure and how leases, loans and equity affect the ratios. The study is based on a ten-year period between 2000-2010 in Sweden. Investments in finance is a complex and interesting subject to study, there are many factors that can affect how the company best choose their investments when they have many great business investment the decisions plays a greater role. The aim is to find an optimal capital structure from a financial investment point of view. The purpose will be answered by the following research question: Are there significant differences between leases, loans and equity financed fleet of factors, profitability, tax, turnover, age, and cyclicality. The study will also examine how debt is related to profit margin, DuPont and the tax, all through a regression analysis. Then were plausible economic theories for the study.
Trafikklasser för markplattor av natursten : förslag till klassificeringstabell
This report deals with hard surfaces and the factors which are behind the criteria for dimensioning, also dependent on the level, or volume, of traffic. A test was made on slabs of two kinds of natural stone. This was made to see if the values that were reached for breakload was transferable to the same tables that the concrete industry is using for surface dimensions of slabs and paving stones. The test showed very high values and the result, together with the written study, led to the author?s suggestion for a classification table where slabs of natural stone were divided in to different classes depending on traffic, thickness and durability..

Påverkan på TED- spread under den nuvarande finansiella krisen
The purpose of this essay is to test for significance between TED- spread and four different macrovariables, housing prices, Federal funds rate, Asset Backes Securities and mortgage volume. Multiple regression has been used to search for significance between the dependent and the four independent variables. Our data consist of quarterly reports from January 1998 to June 2008. Our conclusion is that all of the four variables show a significant relation with TED- spread. The model explains 76 percent of the variation in TED- spread..
Matting of Natural Image Sequences using Bayesian Statistics
The problem of separating a non-rectangular foreground image from a background image is a classical problem in image processing and analysis, known as matting or keying. A common example is a film frame where an actor is extracted from the background to later be placed on a different background. Compositing of these objects against a new background is one of the most common operations in the creation of visual effects. When the original background is of non-constant color the matting becomes an under determined problem, for which a unique solution cannot be found. This thesis describes a framework for computing mattes from images with backgrounds of non-constant color, using Bayesian statistics.
