Miljöbyggnad, GULD värt? : En undersökning av fastighetsägares erfarenheter och tankar kring ett nytt certifieringssystem

During the past few years an increased attention has been paid to environmental issues in the construction and property sector in Sweden. In order to simplify the work with these issues a Swedish environmental certification system for buildings called Miljöbyggnad has been developed. This thesis aims to investigate the opinion of a selected number of selected property owners of Miljöbyggnad. From that basis recommendations and actions for the future work with the system will be presented.The investigation has been conducted through personal interviews with five property owners. The main issues that the interviews have been based on are their purpose, experiences, perceived complications and future prospects in terms of certification using Miljöbyggnad.The system intends to be cost-effective, simple and to offer a relevant environmental assessment of buildings and the result from the report indicates that this is largely fulfilled.

Tuppens och Förmiddagens filosofer : Thoreau och Nietzsche och uppvaknandets filosofi

AbstractThis paper is about the philosophies created by Henry David Thoreau (1817-1862) and Friedrich Nietzsche (1844-1900). The purpose is to show the high degree of similarities between Thoreau?s and Nietzsche?s philosphy.At first glance, it seems far-fetched to suggest an affinity between them; the differences in style and choice of subjects, have most certainly contributed to the fact that very few comparisons so far have been made. There is no evidence that one experienced any influence over the other, neither writer seems to have been aware of the other. Also their different areas of use during the 20th century, may have influenced the almost total lack of search for affinity.

The Low Line : ett gestaltningsförslag med inspiration från The High Line

In the summer of 2009 the High Line opened in New York, a park built on an out-of use elevated rail viaduct. The park meanders its way through the buildings and allows the visitor to see the city from a totally different perspecive than we are used to.I have made a Design proposal in Eriksdalslunden, Stockholm, with inspiration from the High Line. The proposal is based on design ideas of a park I logically call the Low Line, as the place isn't elevated as in New York, but lowered. The two places have some similarities, mainly the strong urban identity and the tracks crossing both areas. They also have very obvious differences, above all the fact that Eriksdalslunden is situated in a swale and is defined in a third dimension by the high bridges that crosses the area.The High Line is designed by James Corner Field Operations, and they have been working using their motto 'Keep it Simple, Keep it Wild, Keep it Quiet and Keep it Slow' during the whole process, words that normally aren't associated to Manhattan.

EC-Winder

Have you ever had problems sorting your cables, are the winders you use too big and crude then the EC-winder is the product for you. The EC-winder concept is a compact and intelligent winder for home application. Its simple design and subtle looks enables it to blend in with the surrounding environment. Its function is designed so that it with ease can be handled by any one after only a couple of instructions. You simply thread the cable trough the opening on the winder and then you rotate the upper part until the cable reaches the desired length. After use the winder can be opened to enable easy extraction of the cable..

Charlie och Sara : Narration, heteronormativitet och lesbiskhet i Margareta Subers Charlie

This essay explores the novel Charlie by Margareta Suber (1932) through lesbian narrative theory. The result is a revealing on how the lesbian main character can be established as a lesbian subject against the male and heterosexual narrative; how she escapes a simple male positioning in the narrative, how she subverts categorisation, how she parttakes in female bonding, and how she disturbs heteronormativity..

Produkthype: En fallstudie (En kvalitativ undersökning om vad som ligger bakom en produkthype)

To identify the underlying forces behind a product hype is difficult and the findings often seem random and unclear. To create a better understanding behind the affecting mechanisms would consequently be a valuable addition to the surrounding research area. The purpose of this paper is to understand if there exist common denominators between different product hypes and in such a case, which these are and how they function. By conducting a case-study on four products which have enjoyed immense sale success on the Swedish market, the possible presence of structural resemblance will be analyzed. From the study we can conclude common denominators such as the presence of an underlying trend and an overbalance of indirect decision basis do exist.

Vem eller vad sätter priset? : En kartläggning av inköpsmarknaderna för tre metaller (Krom, Molybden, Vanadin)

Detta arbete utförs efter en förfrågan från Uddeholm Tooling om att försöka kartlägga riskerna på inköpsmarknaden för metallerna krom, molybden och vanadin. Då detta anses vara mycket svårt föreslås här istället en kartläggning av marknaden för respektive metall, detta för att ge en bild av hur marknaden ser ut och vilka aktörer som finns.Frågorna som behandlas är var bryts, förädlas, konsumeras respektive metall? Hur varierar priserna, beskrivs priserna bäst med en random walk eller med en mean reverting stokastisk process.Det visar sig relativt snart att det är mycket problematiskt att inhämta relevant data. Speciellt då dessa metaller inte handlas öppet utan där kontrakten mellan köpare och säljare är konfidentiella. Priserna som rapporteras baseras på månatliga intervjuer med köpare, säljare och traders som utförs av branschmagasin.

Social behaviour and time budget of breeding bulls

The aim of this study was to investigate the social behaviour and time budget of breedingbulls kept at VikingGenetics, Falkenberg in Sweden when the staff was off duty. It was ofinterest to see if there was any difference between bulls housed in group pens and bullshoused in individual pens. It was also of interest to investigate if there was any differencein the behaviour between the dairy breeds Swedish Red (SR) and Swedish Holstein (SH).Sixteen bulls were used in this study. Eight bulls kept in individual pens and eight bullskept in group pens were used. The individually housed bulls had a social gate with widerbars where the bulls could but their head and neck through to have social contact with thebulls in its neighbouring pens.

Prislisteoptimering för ett sågverk - Jarlträ AB :

This report is a thesis work for a B.Sc. in Forestry at the School for Forest Engineers, SLU. The work was an assignment from Jarlträ AB which is a privately owned sawmill located in southern Småland. The aim of the work was to investigate the economical result of different pricelists and how to adjust different parameters such as length correction to give an optimal result. The pricelists was examined through a computer program (SilviA). The pricelists was made in the program and after that a simulation was preformed with a selection of random sampled trees gathered from the area nearby the sawmill.

Metodik för detektering av vägåtgärder via tillståndsdata

The Swedish Transport Administration has, and manages, a database containing information of the status of road condition on all paved and governmental operated Swedish roads. The purpose of the database is to support the Pavement Management System (PMS). The PMS is used to identify sections of roads where there is a need for treatment, how to allocate resources and to get a general picture of the state of the road network condition. All major treatments should be reported which has not always been done.The road condition is measured using a number of indicators on e.g. the roads unevenness.

Hållfasthetssortering av plankor med hjälp av röntgendata

The aim of this thesis is to find a statistical model that sort logs according to a predicted modulus of elasticity on the sawn boards. The input parameters for the model are X-ray variables from an X-ray scanner. For some of the log classes sawn at the sawmill it is desirable to have a narrow distribution of modulus of elasticity on the sawn boards. 250 pine logs from five different diameter classes were numbered and followed through the sawmill process. Log data were collected from X-ray and 3-D scanners in the log intake.

Utvärdering av precisionen hos sensorer för tröghetsnavigering

Rotundus AB är ett världsledande företag inom området för sfäriska robotar som håller på att utveckla den markbundna farkosten GroundBot(tm). För att detektera robotens translations- och rotationsrörelser används accelerometrar och hastighetsgyron. Dessutom används sensorerna för tröghetsnavigering när GPS-täckning saknas.Målet med projektet innebär att ta fram en metod för att utvärdera precisionen hos sensorer för robotens tröghetsnavigeringsenhet. Metoden koncentrerar sig på fyra av sensorernas felkällor: Skalfaktor, bias, slumpvandring och biasinstabilitet.För att beräkna skalfaktorn och biasen används linjära minsta kvadratmetoden där utsignalen från sensorn anpassas mot ett teoretiskt värde. Slumpvandringen och biasinstabiliteten utvärderas med Allans varians..

Chalmersmodellens applicering på starkt överkonsoliderad lera

In this master?s thesis real settlements for the over consolidated clay below Arenahallen in Halmstad are compared with two different models for settlement calculations; Chalmersmodellen without creep and Chalmersmodellen with creep. Chalmersmodellen with creep is based on Terzaghi?s consolidation theory with an addition to creep. The purpose has been to find out whether Chalmersmodellen with creep can be used for this clay or if Chalmersmodellen without creep should be used instead.

Vibrationsbaserad maskinaktivitetssensor

I detta projekt undersöker vi om man kan bygga en maskinaktivitetssensor medhjälp av en enkretsdator som genom en accelerometer mäter en maskinsvibrationer. Sensorn skall generera en statussignal. Accelerometern ger enmätbar signal baserad på maskinens vibrationer. Enkretsdatorn används för attsampla, transformera och analysera signalen och generera statusinformation.Med LabView kan vi spara, studera och analysera olika signaler och olikatransformer. Vi studerar maskinvibrationer i LabView och beslutar att 5 kHzsampling räcker för att fånga intressanta vibrationer.

Effektmätning i pump

The interest for power and energy measurement has greatly raised with todays increasing electricity prices and enviromental awareness. In the search for energy efficient solutions, the measurements are more complex due to increasing of non linear components. Harmonics and non sinusoidal voltages put high demands on sampling and filtering. Meanwhile, the price must be controlled so the customer still will find it interesting to invest in smaller plants. ITT W&WW asks for a robust, heat resistant power meter with compact dimensions to allow mounting inside the casing of a pump.
