Åtgärdsförslag och känslighetsanalys vid energieffektivisering ur ett fuktsäkert perspektiv : En fallstudie på timmerhuset Sofiedals herrgård

This thesis investigated the possibilities to resume cultivation of an old manor house built of timber and what this would mean from an energy and moisture perspective. The building in this case study is named Sofiedals mansion and was built in 1858 in Valbo 11 kilometers west of Gävle.The structure of the house was documented and used as a starting-point for carrying out calculations focused on energy and moisture aspects. With the help of a number of computer programs and a conducted air tightness test, the buildings energy consumption were calculated and compared with the current building regulations.In addition, the building was analyzed considering energy retrofitting and what it meant for moisture problems. The energy retrofitting consisted of additional insulation, decreasing the buildings permeability through air sealing; window and door replacements. When a building is equipped with natural ventilation it is difficult to know its precise performance and how an energy retrofitting affects it.

Värdegrunden i skolan : En kritisk studie av innehållet och arbetet med skolans värdegrund i en senmodern kontext

The purpose of this study is to investigate the content and work processes regarding the values written in the curriculum for Swedish high schools and compare it with theories regarding the individualized society and political moralism. After the clarification of the content in the values of Swedish high schools and the work processes that are supposed to give students fundamental understanding about them, I analyze and compere it to the theories that are presented in the study. The main questions of the study are the following: What kinds of values are found in the curriculum for Swedish high schools? In general, how do Swedish high schools work with the written values when focus have gone from education and learning to instrumental knowledge, results, abilities and flexibility?The result showed that the content and work processes regarding the values in Swedish high schools are purely instrumental and moralistic. Due to the fact, that the individualized society and the neoliberal ideology do not require reflection and real understanding regarding the values.

Förskollärares syn på Kvalitet i Förskolan

My purpose with this work is to find out how it relates with pre-schoolteatchers view about a quality in comparasion to control document, Lpfö-98, and with factors pre-schoolteatchers consider effects quality in pre-school describe pre-schoolteatchers view on that high quality is in pre- school.The investigation has been done by quality interviews with five pre- schoolteatchers working in pre- school. The results show that they do not make a difference between what are high quality and the factors that affect the possibility of creating high quality. Most important is qualified and engaged educationalist in the pre- school who who shows a good attitude towards the children, and where development and learning is central. The most decisive to a pre- schools quality are the personell who work there. A conditon to achieve high quality in pre- school is a head who knows the pre- school activity and its curriculum, and who takes active part in the activity, invites to discussions and offers pertinent competence development.According to the leading document Lpfö-98 you will achieve high quality by offering children rear and care.

Organisationsstrukturen & styrsystemets användbarhet - En fallstudie av Perstorp Performance Chemicals

Syfte:Syftet är att analysera och beskriva styrsystemets användbarhet utifrån vald organisationsstruktur i ett decentraliserat företag. Problem:Eftersom strategin utgör en grundtanke som ska förena och skapa en gemensam riktning för individer eller organisationer är det en central del av en chefs roll att sträva mot att skapa framgångsrika strategier och att implementera dessa. Enligt forskning kommer företagens diversifieringsstrategier leda till att de decentraliseras och organiserar sig efter divisioner. En decentraliserad, divisionaliserad organisationsstruktur har fördelar men också nackdelar. Eftersom organisationsstrukturen och styrsystemet ska samverka ställer strukturen krav på styrsystemet.

Utvärdering av fjädrande statorfötter : Nytt koncept i vattenkraftgeneratorer

This thesis is an evaluation of a new design concept for statorfeets in Gallejaur hydro power plant. Founder of the work is Vattenfall AB Vattenkraft. During the 70- and 80´s nuclear power began to be phased in to the Swedish grid, which meant that hydropower became an important source of rules. The generators began running in so called intermittent operations instead of basic operations, which meant 300-600 start/stop per year instead of one-ten numbers start/stop per year. In order to deal with the thermal forces that arise at every start and stop suppliers began to mount so called sliding joints, which is to take advantage of these forces and maintain the stator shape.

3D-skrivarens intåg i immaterialrätten : - Om 3D-bilder, 49 § URL och vikten av lämpliga avtalslicenser

The current study aimed to test the public self-consciousness impact on creative performance. An experimental design was used in which 40 participants were randomly assigned to two groups, one of which was the experimental group and the other was the control group. A mirror was used in the experimental group to induce public self-consciousness among the participants while they performed creativity tests. A consequence test was used where the participant had to give suggestions for the given scenario "What would happen if everyone became blind?" which was then measured in the number of proposals (fluency).

Nedbrytning av propylenglykol i uppsamlingssystem för avisningsvätskor : En studie utförd vid Stockholm Arlanda flygplats

Deicing fluids based on Propylene glycol are used at Stockholm Arlanda airport to remove or prevent ice on aircrafts. The high oxygen demand of propylene glycol can cause oxygen depletion in rivers downstream from the airport if not collected. Mass balance calculations made by Swedavia indicate that the actual amount of gathered propylene glycol is underestimated. Suspicions that propylene glycol is degraded in the stormwatersystem designed to collect deicingfluids, called the B-glycolsystem, have to be investigated in order to establish with certainty that no propylene glycol in other ways leaves the B-glycol system.The purpose of this study was to determine if degradation of propylene glycol is present in the B-glycol system and also to estimate the extent of the degradation. Propylene glycols high biological oxygen demand can cause oxygen depletion in waters downstream from Stockholm Arlanda airport if not collected.

Beräkning av direktljud genom homogena betongväggar : Densitetens och tjocklekens påverkan på reduktionstalet

Today's urban centers become denser, which contributes to higher demands on sound and noise. It is therefore highly relevant to build homes with good sound environment while maintaining living space. This thesis aimed to reduce the current concrete walls and see how the mass law affects the reduction index value and flanking transmissions. Handmade calculations were calculated according to the Swedish standard SS-EN 21354-1, where only air sound was calculated.Calculations we­­­re performed on wall elements with different weights and thicknesses, and compared with results from Bastian.In Bastian calculations of flanking transmissions were also made, this was made to see the impact of the flanking transmission when changing the mass per unit area. Mass law's impact was examined by flanking transmission and the result shows that they are not affected as long as the ratio between the thickness and the density remains the same.A questionnaire survey was conducted to determine the actual sound experience; this questionnaire was conducted on three concrete buildings in Växjö.

Varför ska vi välja just dig? : En studie om trenden performance urval och dess inriktningar.

I dagens arbetsliv används olika urvalsprocesser för att finna lämpliga kandidater till lediga tjänster. Inom en traditionell urvalsprocess selekteras kandidater utifrån en skriftlig ansökningshandling där kandidatens formella kompetens i form av tidigare meriter och erfarenheter lyfts fram. Den traditionella urvalsprocessen har nu utvecklats och delvis ersatts av nya metoder för att finna lämpliga kandidater. Utvecklingen mot nya urvalsmetoder ser vi som en trend i arbetslivet. Trenden har uppstått då en rad inriktningar har uppkommit som ett komplement till den skriftliga ansökningshandlingen.

Downside Risk - En studie av riskkompensation på den svenska aktiemarknaden

This paper investigates the compensation for risk in the context of the Swedish stock market with a special focus on downside risk. Using daily market data collected from the A-list of the Stockholm Stock Exchange between the years 1983 and 2005 the purpose is to answer the question whether Swedish investors are compensated for holding stocks with high downside risk, measured as downside beta. Using panel data analysis it is shown, in accordance with most previous evidence in international research, firstly that stocks with high beta values on average experience higher returns than stocks with low beta values, and secondly that stocks with high downside beta values experience higher returns than stocks with high beta values in general. On the other hand, cross-sectional regression methodology using a bivariate regression approach shows that downside beta does not explain excess returns very well. Instead, regression analysis suggest that high upside beta does a much better job in explaining excess return over this time period compared to downside beta.

Utveckling av dynamiska farthinder

The aim of this Master of Science Thesis is to develop guidelines and improvementsuggestions of RiNOVA Traffic AB?s dynamic speed bump. The project started with athorough pre study of the design and its function to find out how passing vehiclesaffects the dynamic speed bump. The majority part of the pre study was to createnecessary mathematical models to explain the arisen forces and strains.The results of the mathematical models gave necessary information about the designregarding weaknesses and flaws. The most critical ones where those which interferedwith the design?s performance and reliability, and therefore needed to be corrected.These problems where more thorough analysed and discussed with experts before thefinal guidelines and improvement suggestions where developed.The parts of the design that had to be redesigned were the extension springs and thebearing that enables the dynamic properties.
