Cirkulationsplatsers inverkan på vägtrafikbuller
I dagens samhälle är runt två miljoner svenskar störda av trafikbuller, samtidigt som bilismen och vägtransporterna ökar. För att få en säkrare trafikmiljö med ett jämnare körsätt är det populärt att bygga om vanliga korsningar till cirkulationsplatser.Denna rapport fokuserar på vad som händer med bullernivåerna då trafiken passerar en cirkulationsplats. Undersökningarna har genomförts genom att beräknade bullernivåer jämförts med uppmätta värden från olika cirkulationsplatser. Arbetet inleds med en litteraturstudie om ljud- och bullerfrågor.Bullermätningar utfördes vid totalt åtta olika cirkulationsplatser, där både ekvivalentnivåer och maxvärden samlades in. Därefter beräknades medelvärden av dessa.
Val av byggproduktionsmetod/ Praktikfall Klammerdamm : Golvgips eller avjämningsmassa
This report is about how to decide which method is the most suitable as floor covering at projectKlammerdamm in the centre of Halmstad. The covering has to be fire resistant and soundproof inorder to protect the wood structure and stop noise from traveling between apartments. There aretwo possibilities either traditional gypsum board or gypsum-based self leveling underlayment.The roads around the construction site are narrow. A regular twenty-five meter long truck has nopossibility to reach the site. The construction site is small and the storage area is limited.
När ska dieselelektrisk framdrift av fartyg väljas?
Diesel electric propulsion is in many ways a good alternative to conventional shaft propulsion, both economically and environmentally. There are also many other good side effects which need to be considered, i.e. better manoeuvrability, more efficient use of space and less noise on board. However, there are applications where diesel electric propulsion is not profitable. Large ocean going ships? profitability is much depending on fuel costs and the diesel electric alternative cannot compete on long journeys with large low speed engines.This thesis will treat the aspects of choosing between a diesel electric system and a classic mechanical propulsion system.
Flexibel ljudinspelning för talkvalitetsanalys
This report describes how wavefiles can be recorded with programs written in the C++ language . The report also describes how the recorded sound is handled before it can be analyzed. The report describes the different parts that make a wave file to a wave file and how Windows handle these files. There is always some silence or noise of unknown length that passes through the system before some interesting sound arrives. That silence or nose must not be recorded and therefore some function must be developed that can detect interesting sound or speech.
Daily rests of wild boar Sus scrofa sows in southern Sweden
For a few decades, the wild boars are established over large areas in southern and centralSweden. Where they cause problems in terms of damage to crops in the agriculturelandscape, where rooting, browsing and trampling, but also damage to the crop when wildboars chosen daily rest in the cultivated fields. Along with the growing number of wildboars the rate of car accident with wild boars has also increased.Here I examined the daily rests of wild boar (Sus scrofa) sows in southern Sweden, todetermine the factors which the wild boars sows choose for daily rest. By determining whatfactors are important in this selection of daily rests, we may be able to make managementmeasures to reduce the damage wild boars make in the agriculture landscape by attractingthem to places where they do less economic damage and accidents on roads.In this study I have examined 123 daily rest positions from 14 different individual wildboar sows fitted with GPS collared in Southern Sweden, Skåne County in Christinehof,Högestad Kronovalls estate. Data was collared over the years 2004-2006 during the periodfrom June 1 to September 30.
Caso Skanska
Caso Skanska is an incident that occurred in Argentina and regarded corruption and bribes to government officials. This study investigates how this incident could occur and how it can be explained. The theoretical framework used is the dynamic interaction model, stakeholder theory, embeddedness theory, the political perspective and corruption theory. The method used is qualitative and it consists of data gathered through semi-structured interviews in Sweden and Argentina as well as other sources of written information of relevance for the study. The authors conclude that Caso Skanska could occur due to the lack of strong institutions as well as transparency.
Butikskommunikationens viktiga roll
Studien är främst till för att bringa klarhet i hur en butik bör arbeta med visuell marknadsföring för att nå konsumenten och skapa en positiv reaktion hos denne. Vi har dessutom undersökt vikten av relationen till kunden, och hur företaget arbetar med det genom relationsmarknadsföring. Vi har fått fram vårt resultat genom marknadsundersökningar och observationer inne i och i anslutning till en butik, samt genom en intervju med den ansvarige för butikskommunikationen i samma butik. Till vår hjälp har vi arbetat med Peak Performens Borås, det är kring denna butik hela studien kretsar.Den personliga intervjun med den person som är ansvarig för butikskommunikationen på Peak Performens Borås gav oss information om problem och utmaningar ur deras synvinkel. Materialet gav oss även bra bakgrundsinformation att jämföra resultaten från marknadsundersökningarna och observationerna med.
Vem syns i rutan? : En studie över SVT:s och TV4:s sportsändningar ur ett genusperspektiv
This report is an analysis from a gender perspective of more than three hundred minutes in sports broadcasting on SVT and TV4. The study explains how air time is divided between male and female athletes as well as which sports, male or female, get the most air time. The sports are also categorized according to attitudes about the sports being masculine, feminine or neutral. In this way the study also shows the categories of sports that are given the most airtime.Our view before the study was that from a media perspective, the Swedish sports world was very male dominated. The results show that male athletes get more exposure than female athletes on both channels, this despite the fact that the membership of the Swedish sports clubs is fairly evenly divided between men and women. .
Är det möjligt att använda SCR-rening av rökgaserna vid inblandning av avfall i biobränslet?
Waste appears to be a low-cost fuel compared to biofuel. This Masters thesis was conducted for Vattenfall Utveckling AB and deals with how waste in the fuel affects the performance of a SCR-catalyst. Different mechanisms of deactivation were surveyed, focusing on the poisoning mechanism. A literature study was carried out, which was used as a reference when analysing the results.Small samples (9x2x2 cm, 64 pieces) cut out from a full-scale unused honeycomb catalyst were exposed up to 1500h in two different combustion plants, Johannes in Gävle (co-combustion) and Högdalen in Stockholm (waste-combustion). The activity was measured mainly at 300°C but also at 250, 350, 375 and 400°C.
Konvertering från luft till vätskekylning av elektronik
A Swedish electronics company wants to make the cooling of one of their electronic components more efficient. They propose that a retrofit liquid cooler is the way to achieve this goal. The current air cooling has high energy cost due to the high amount of power needed to power fans and heat exchangers. Using high volumes of air for cooling also leads to noise pollution. The conversion from air to liquid cooling would possibly make the operation of the electronics more cost efficient and less noisy.The purpose of this project is to theoretically evaluate different concepts of drawing the heat generated by the electronic component in to a fluid, using numerical calculations in Matlab and FEM simulations in ANSYS.
Ungdomars attityder till tobak
Denna undersöker hur ungdomars attityder till tobak påverkas av olika typer av exponering. Det finns idag specifika begränsningar och restriktioner för hur marknadsföring av tobak får se ut i Sverige men trots det exponeras vi dagligen på sociala medier, i affärer och liknande, ofta utan vidare medvetenhet. Vi ville genomföra en undersökning över hur ungdomars attityder till tobak skapas och påverkas av sociala, interna och externa påtryckningar. Genom våra två fokusgrupper har vi lyckats samla önskat material och där av kunnat klarlägga flera svar till hur olika typer av exponering påverkar ungdomars attityder till tobak..
En bild säger mer än tusen ord? En analys av språket i bilden och dess betydelse vid skapandet av ett kvinnligt subjekt i verk av Sejla Kameric, Barbara Kruger och Jenny Holzer.
How does language work within the context of art and image? In what way can text contribute to the reception of an art work?In this essay I examine the role of language and how it, in selected works from the artists Sejla Kameric, Barbara Kruger and Jenny Holzer, becomes part of the deconstruction and exposure of social structures and issues of gender. My aim is to examine whether this deconstruction of rules and structures helps to bring about a forming of a female subject in oppsition to the more common female object..
Dynamiken mellan sändare och mottagare- en studie av Acne Jeans, Filippa K och konsumenten i Stockholm och Göteborg
The consumer today is affected by a considerably larger number of world surrounding factors than she used to be, borders between different cultures and other consumer differences are being erased to a growing extent. The consumer can easily get its inspiration from many different directions which become clear in the common life. We eat sushi for lunch, we?re driving German cars and we?re having dinner with international business partners. The community also exposes the consumer for a more intense noise from offers, impact and marketing.
Nakna sanningar från Amerika : Moderniserings- och kulturperspektiv från svensk-amerikanska berättelser
The purpose of this study is to shine a light at the Swedish americans impressions and attitudes against the American society from the perspective of modernization and cultural attributes. This, with a reference frame of the deeply politically rooted European conception of America as a threat to the cultural well being, and as a thriving materialistic and progress bound constitution.The result shows that the attitudes against America in the descriptions were not all comparable with the conception that was conducted in Europe. However, the experiences altered whereas the study attends two different periods of time. The experiences differenced due to the growing exposure to cultural diversity and a modernization that grew faster in America than anywhere in the world. Not to mention the change of experiences and expectations that was with brought from a changing atmosphere in Sweden.
Factors affecting crop insurance decision : a survey among Swedish farmers
Farmers are constantly facing changes, and the exposure to risk requires monitoring these changes. Financial risks, institutional risks, market risks and production risks are the different risk categories that the farmers face. Production risks stems from factors the farmer cannot affect or is beyond his control. The crop?s output is the basis for the primary income of agricultural operations, which is why it is important for farmer to manage their production risk.
A tool to reduce the consequences of production risks is crop insurance.
