Hur påverkar byggnadsmaterial av stål en induktiv hörslingas fältstyrka samt frekvensgång?
This research analyzed differences in measurements of magnetic field strength and frequency response in five audio induction loops installed in rooms of wooden construction materials and five audio inductive loops installed in rooms of steel reinforced concrete constructions. The inductive loops were installed at floor level and the measurements were made at the listening height of 1.2m. Measurements of background noise, field strength and frequency response were made at fifteen different measurement points across the room. The research measurements showed that there are differences in field strength and frequency response between these two conditions, whether the audio induction loop is installed in a wooden construction or the audio induction loop is installed in a reinforced concrete construction. The results had a significance level of p=0,05..
Tylö : Sauna Lighting
Tylö AB is the leading manufactor of sauna cabins in Europe, but there is a lackof a sauna lightning produced by Tylö. The project of developing a new saunalightning series was assigned two students at the developmentengineeringprogram at Halmstad University. The main problem with lightning in the saunais the heat and security aspect. The selection fell on LED technology as thelightning source, thanks to its small measures and low heat emission.The work of constructing of a lightning armature which the capability of coolingdown the LED lightning was carried out during autumn ?06 and spring ?07.

Ekonomiska styrmedel för förpackningsavfall : En studie om vad som påverkar återvinningen i EU
In 1994 the EU directive of packaging waste was adopted. The result was that all EU member states developed different systems to manage packaging waste and recycling. This paper examines the various systems and the factors that affect the level of recycling. This is done by a cross-sectional study between countries. The results of my study suggest that take-back system generates less recycling than other systems, the mandatory deposit system can affect the recycling in a positive way.
"Prata högre! Jag hör inte vad du säger" : En kvalitativ studie om elevers och pedagogers upplevelser av Södertäljes nya skolmodell
"Speak up! I can?t hear you"This qualitative study is built on an investigation of a newly instated model that is used when building or renovating schools. The principles of the model are based on building schools with an open plan design where the walls are made of glass and the classrooms are not shut closed by walls, instead the classrooms are completely open except from screens that are used to indicate the ambit of the rooms. This model has been well debated and that is the reason why we chose to do this study.The purpose of this study is to find out how students and teachers experience this model. To do this we have done interviews and observations.
Utveckling av en metod och en utrustning för mätning av bränslesprayers rörelsemängd
A new type of device for measuring thev m& ?rate of fuel sprays from a diesel fuel injector has been developed and the various steps in the development are described. The device works by deflecting all of the sprays from the injector at the same time by using a bell shaped deflector. A load cell consisting of a machined steel part with strain gauges mounted on it measures the resulting force. The shape of the curvature in the deflector bell shape has been evaluated by photographing the flow in a 2D?version of the curve shape.
Spårbilsstation i Upplands Väsby kommun
Upplands Väsby municipality has a vision that podcars in the future will become an effective alternative in public transport, with reduced car-dependency as a result. The system would also attract new inhabitants and businesses to the municipality.This report deals with various issues that podcar stations may face. Also, suggestions for possible track laying at the stations and station design are presented. Two areas are investigated. Eds allé which is a neighborhood that is planned for housing and where the station may be planned into the cityscape from the start.
Könsmärkning och statusrelevans i folkbiblioteksvärlden
The main purpose of this Masters thesis is to examine gender division in public libraries by reviewing literature and interviewing eight public librarians and two chief librarians. The reason why we decided to investigate this topic is the lack of research concerning sex-segregation in library and information science. By choosing this subject we intend to deepen the understanding of the significance of gender both within the public library and of the occupation in general. Some researchers claim that the low status of librarianship is a result of the large proportion of women in the profession. We want to find out how our informants view the relation between professional status and female domination.
Risker inom Svartöstadens industriområde: beräkning av individ- och samhällsrisk
Rapporten är tänkt att fungera som ett informationsdokument för de företagen samt personer och funktioner som påverkas vid en eventuell olycka i Svartöstaden. Förhoppningen är att rapporten ska öka förståelsen för vilka risker som finns inom området. Vidare är det även önskvärt att densamma skall kunna fungera som ett styrdokument vid eventuell utökad bebyggelse utav Svartöstaden samt närliggande områden. När en av Norrbottniabanans föreslagna sträckor planeras i direkt anslutning till området, finns det därav ett behov av en sammanställning av de olika företagens specifika risker. Svartöstaden byggdes upp under slutet av 1800-talet, den malm som framställdes vid gruvan i Malmberget transporterades ner till Luleå för vidare transport via fartyg.
Min onkel : Film blir bok
The Sand Catcher The thesis project The Sand Catcher investigates the encounter between permanent structures and an ever-changing landscape. The migrating sand dune Råbjerg Mile in northern Denmark is 40 meters high and moves more than 15 meters every year. By introducing a solid structure on the site, the fast movement of the sand dune is emphasised and thereby our view of time and space.Through intuitively building models with varied openings and densities I investigated how architectural elements react with sand. From these experiments a series of spatial features and effects were found, generated from the meeting with the sand.The Sand Catcher is a solid and permanent structure. The sand is the liquid element that generates new spaces, circulations and experiences.
Slipning av rostfritt kromstål Sandvik 12C27 i skridskoskenor
Martensitiska rostfria kromstål som Sandvik 12C27 har, tack vare små hårda karbider i strukturen, en förmåga att hålla skärpan längre än ett kolstål. Trots detta så möter skridskoskenor av kromstål motstånd från slipare. Detta främst beroende på att det uppför sig annorlunda när man slipar det, jämfört med ett mer traditionellt kolstål. Framförallt gnistbildningen upplevs som annorlunda. Syftet med arbetet var att identifiera vilka problem man har vid slipningen idag samt ta fram förslag på hur man minskar dessa problem.
Konstruktion och utformning av skydd till spolverk
This thesis has been carried out in cooperation with Burseryds Bruk AB.Burseryds Bruk is a company that manufactures steel strapping. The thesis isabout developing a concept of protection that should be used to protect theoperators from the rotating parts of the machinery lines. The aim of the projectwas to improve work safety for operators working at the machines by producing aconcept for a protective device. The project's first part was based on ergonomic data collection methods tounderstand the operations performed on the machine and the hazard occurringduring the process. The methods used to collect data were, interviews,observations and questionnaires with the operators of the company. This was thenused to make the ergonomic analyzes hierarchical task analysis and link analysis. The data collected from the company's operators was used create 10 conceptswhich were then evaluated.
Vibrationsanalys : Vibrationsproblem i travers
Som en del i Maskiningenjörsutbildningen vid Karlstads Universitet har detta examensarbete utförts under en 15 veckors period. Uppdragsgivare är Scana Steel AB:s stålverk i Björneborg och arbetet behandlar en av deras traverser. Arbetet bestod i att lokalisera och om möjligt förinta vibrationer som uppfattas som störande i förarhytten till traversen. För att lokalisera vibrationerna har olika analyser genomförts med hjälp av SpectraPro samt Vibshape, vilket är två mjukvaror tillhörande mätutrustningen Easy Viber. Dessa två program ger oss möjlighet att se animeringar av traverskroppens rörelse och visa spektran för specifika punkter.Analyserna visar på att förarhytten huvudsakligen rör sig vid tre olika frekvenser.
