Akustisk mätning av U-värde

This pre-study investigates the possibility of U-value measurements through an acoustic method. A hypothesis about an acoustic model built on acoustic theories combined with U-value theories is presented to answer the questions: ? Can U-value theory be combined with acoustic theories? ? Can the coefficient of heat be affirmed trough an acoustic measurement? The idea for this dissertation begun with a logical idea in mathematical similarity, between the coefficient of heat transmission units and sound intensity units. The U-value theory is based on assumptions such as initial resistance for inner walls and initial resistance for outer walls. The resistance in the material is interpreted through sound intensity theory. The argument is built upon mass law theory, which means if the frequency or thickness of the material layer doubles it implies an increase of sound reduction by 6 dB.

Introduktionskurs, underprissättning och institutionellt ägande : samband mellan prissättning och ägande vid en börsintroduktion

Who would not like a profit of more then 95 % in a day? Investors in Sweden had thatopportunity, if they had bought a certain stock on the primary market and sold it on the firsttradable day at the Stock Exchange. Most of that profit fell into the hands of institutionalinvestors. The reason for this extraordinary profit was the underpricing of that specific stockduring its initial public offering (IPO).Our report aims to analyze the relationship between offer price, underpricing and theownership structure of stocks. Our investigation is based on all IPO?s on the Stockholm stockexchange during the years between 2000 and 2005.

Alternativa byggsystem för att minska transmissionsförlusterna på miljonprogrammets byggnader

The purpose with this project is to explore and verify three renovating systems for Miljonprogrammet (common expression forbuildings constructed during the years 1965-1975 when over a million houses where built in Sweden) to take measure to thelargely transmission losses of these buildings. Many of the buildings from this period have similar constructions and thereforethe same techniques can be used to renovate several of them. This project only considers the climate scale, although thereare many more factors to concern for to efficient the buildings of Miljonprogrammet.This thesis presents examples of renovations carried out using two of the three renovation systems.The essay presents a reference house of choice on which we apply the three systems and calculate the new U-values,consumption of energy and the investment costs. The new U-values the building is given is matched to the values ofrecommendation for passive houses. Our reference house is a two story apartment building, located in the village ofLammhult, with brick facades at the ends and plaster at the long sides.

Rökgaskondensering och skrubber till vedeldade villapannor :

This paper deals with the opportunities for the technique of condensation, for wood fired household heaters, on the Swedish market. In this project the condenser is preceded by a scrubber and both energy exchange and separation of unburnt particles have been studied. The facility studied is connected to a wood stove at 30 kW. The tests would show that the effect from the stove never reached above 16 kW. This might be a result of the low temperature of the water going into the stove, from the condenser. In addition to this the wood was not of highest quality and the stove could have needed some maintenance before the tests.

Humankapitalets roll vid företagsvärdering

This study investigates a method for identifying human capital and its effect on company valuation. We devise a measure for the efficiency of human capital based on the personnel cost. We include all companies listed in the financial and industry sector on Nasdaq OMX Stockholm in an attempt to examine human capital and its effect on firm valuation. Our results indicate that a higher efficiency of human capital has a positive effect on return on assets. However, we find that our measure can be interpreted in two ways; either as a firm?s level of human capital efficiency or its dependency on human capital, to achieve its net sales and revenue.

Kringtjänster för fastighetsmäklare

The amendment of a law which is expected to come may well have a significant impact on the Swedish real-estate broke market. The law change will probably have an effect in the number of ways real-estate brokers will compete as a result of the increasing variety of services offered. In order to gain competitive advantages brokers must be at the forefront in the development regarding the changing market. To do so requires that the company chooses an appropriate range of peripheral services that are profitable. The problem is to choose the ?right? services to convey. The purpose of this paper is to describe the services that are in demand for transmission and how the agents can work to meet the demand of this new market.

En diskursanalytisk studie av Aftonbladets publiceringar kring ADHD

This paper examines the Swedish newspaper Aftonbladets conception of the phenomenon ADHD. The essay regards the language that is used (and the values reflected in it) as a sort of mirror where the public opinion is expressed, established and put forward. Being such a constructive factor in the creation of the phenomenon, the language is considered of big importance and therefore this essay is using a discourse-analytic approach to the problem.The aim of the essay is to achieve a discourse-analytic understanding of Aftonbladets ADHD publications. This paper reaches the conclusion that in Aftonbladet, ADHD is put forward as something extraordinary, not normal and unusual, which results in the subject-positions ?Unwanted?, ?Disabled? and ?Function beneficial?.

Biologisk bekämpning av Fusarium graminearum

Fusarium graminearum causes reduction in both yield and quality in cereal grain worldwide. One of the diseases it can cause is Fusarium Head Blight (FHB). Both sexually and asexually produced spores can infect living plants. Asexual conidia are produced in the mycelium while sexual ascospores form in asci in perithecia on debris. In biological control, living organsims are used to control pests and diseases.

Integrerad hästanläggning : ridhus/stall

Today there is an increasing market for businesses concerning horses, and since we are already running such establishments we sort of speak already have a finger in the pie. Due tothe increasing competition and demands, new and more practical constructions have become a necessity. In doing this project I wanted to make a comparison between having a stable integrated with a manege and having both constructions kept separate. I wanted to compare different layout and make an estimate of costs to see which solution would be less expensive and better with regard to working environment. I will further also deal with different ventilation-systems andlight transmissions.

Vittneskonfrontationer och weapon focus effect: inverkan på vittnens korrekthet och konfidens

Vittnens minne från brottstillfällen påverkas av en mängd variabler vilka kan inverka vid en vittneskonfrontation. I studien undersöktes effekten av vapens förekomst vid en simulerad brottssituation, vilket testades i en vittneskonfrontation enligt Rikspolisstyrelsens rekommendationer. Huvudsyftet var att pröva huruvida ett vapen har en effekt på vittnens hågkomst av ett ansikte (weapon focus effect). Inga egentliga resultat påträffades. Emellertid observerades en könsskillnad gällande deltagarnas konfidens relaterat till deras beslut.

Kortsiktig fosforeffekt av avloppsslam : krukförsök i växthus där järn-, aluminium- respektive kalkfällt slam använts som fosforgödselmedel

The short term effect of phosphorus in sewage sludge was investigated to establish howmuch of this a farmer can grant him- or herself, if using sewage sludge as a phosphorusfertilizer. Possible differences in plant availability between sludge phosphorus precipitatedby iron, aluminum or calcium integrations were studied in a sandy soil at two pH levels.The sludges were analyzed using pot and incubation trials. As the intention was to investigategrowth limitation due to phosphorus deficiency, a soil with low phosphorus supplywas chosen as well as a low phosphorus application rate. Sludge corresponding to 12kg phosphorus per hectare was applied. Treatments fertilized by sludge were compared totreatments where 0, 6 and 12 kg phosphorus per hectare from mineral fertilizer was applied.Every treatment was replicated six times.

Bankers syn på ändringar av aktiekapital, revisionsplikt och redovisning : En fallstudie av svenska storbanker i Karlstads kommun

The amendment of a law which is expected to come may well have a significant impact on the Swedish real-estate broke market. The law change will probably have an effect in the number of ways real-estate brokers will compete as a result of the increasing variety of services offered. In order to gain competitive advantages brokers must be at the forefront in the development regarding the changing market.

Aktiefonder : Ett lönsamt investeringsalternativ?

Background: Mutual funds have become an important part of the Swedish deposit market. Savings in mutual funds add up to almost 20 percent of the households'assets. When the pension reform is carried out all employees are going to have savings both in mutual and bond funds. But only if the fund overperforms the market it is worth investing. Purpose: The purpose of this study is to explore if Swedish mutual funds have generated higher returns than market portfolio in the late nineties.

En designad fluidsimulation

In this report I will describe how an art-directed fluid effect for motion picture can be achieved. This effect will be an explosion with a visual style that is congruent with Pixar's movie Up. To begin with I will analyze the visual components that are used in Up and control the fluid simulation to get the desired visual style. I will briefly explain the background of my thesis, why it is interesting to create designed effects and why it is hard to design fluid effects. In the method I will explain my work process and some of the challenges that arises.

Ekonomisk utsatthet i skolan : - En kvalitativ studie om hur lärare identifierar och hanterar ekonomisk utsatthet bland elever i en svensk storstad

The aim of this essay was to understand how teachers identify and deal with the problems surrounding economic vulnerability among their students.  A qualitative study method was conducted by seven semi-structured interviews with teachers from a big city in Sweden. When analyzing my result I found support in Goffman's stigma theory as well as in previous research. The teachers identify economic vulnerability amongst their students through their material belongings, when the class does something extraordinary, and through how the students communicate. Problems that the teachers can see in the classroom for economically disadvantaged students are that they can be aggressive, unruly and become introverted. Problems with studies and shoplifting are also common.
