Utveckling och utförande av frekvensstudie vid Rapid Granulator AB

The object of this examination project is to produce a method of work sampling at Rapid Granulator AB. The aim is to perform the method at the company and evaluate if it is executable. The study is delimited to the basic construction of the 45-series in the assembly hall.Preparations to produce the method of the work sampling resulted in definitions of activities, a form and a product tree. Several days were spent studying the assembling to learn and understand the entirety.The work sampling result showed a large amount of no value adding time that was used in the assembling. Some of the activities could be reduced and we observed some problems during the assembly process.

Lokal anpassning och implementering av Operation Management System

In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.

Produktkoncept: lekhjälm i vintermiljö : ett nytt produktsortiment

A protection helmet for young people (3-7 years) in winter environment has been developed in this thesis. The result is a concept proposal for development at STIGA Sports AB in Eskilstuna. This thesis work has been performed during 20 weeks, for a Master of Science in Product and Process development at Mälardalen University Eskilstuna Sweden in September 2009 to January 2010. The helmet is shown as a CAD model with detailed solutions to the outer shell, interior and adjustability (in sizes 50-56 cm) which are the three focused areas in the development. Also a physical model in scale 1:1 has been developed and is shown in this thesis work.To achieve the best result possible the process started with an analysis of the market and the product.

Fysiska strukturer i Umeälvens gamla älvfåra och dess inverkan på laxsmoltens utvandringsframgång

The survival of hatchery reared smolts is generally low after release. To get a better understanding of what variables affecting migration success, Atlantic salmon smolts were studied during their out-migration in the old river channel in the lower part of river Umeälven. The area consists of shifting habitat and complex structures which causes difficulties for smolt on their migration out to sea. The aim of this study was to try to determine the effects of feed restriction, fin conditions and different physical barriers in the river, on the migratory behavior of Atlantic salmon smolts in the river Umeälven. The river was divided into six different sections using acoustic receivers strategically deployed along the river. Two-year old hatchery-reared smolts (n=150), in three different weight classes, were tagged with acoustic transmitters.

Lärandets komplexa processer : Om maskulinitet och subjektsskapande i en teknikklass på gymnasiet.

My own experiences as an upper secondary school teacher and the increase in research on masculinity in educational settings that occurred during the late 1990 emphasizing on the gender gap in achievement and grades is the point of departure for this thesis. The aim is to investigate how boys in upper secondary school are constituted and constitute themselves as motivated and achieving learning subjects. Another aim is to see what possibilities there are to form different teaching practices to create other possible positions for me and the pupils. The research questions are 1) How does boys´ construction of masculinity constitute how they see their own ability to be motivated and achieve in school 2) What significance do my shifting approaches and expectations on the pupils as well as teaching have on the boys constitution as learning subjects? To answer these questions I use a theoretical framework of feminist poststructuralist.

RENOVERING AV MILJONPROGRAMMET TILL PASSIVHUS : Implementering av tysk prefabteknik

Construction accounts for about 35 percent of the total Swedish energy consumption and most of the energy is used by the large housing stock from the so-called ?Million program?. In the national action plan the government has put forward in energy efficiency. It is mentioned that existing buildings account for more than 90 percent of what is expected to be the housing stock within the coming 50 years. In order to meet environmental objectives its required that the existing stock be reviewed for energy efficiency. The goverment is now initiating a national framework with a budget of SEK 300 million Swedish crowns per year for five years, starting in 2010 to achieve the goal on energy efficient buildings. Energy efficiency of buildings in both new construction and above all within the existing stock are addressed.

An assessment of public procurement of timber buildings : a multi-level perspective of change dynamics within the Swedish construction sector

The construction and use of buildings in the EU accounts for half of the EU?s extracted materials and energy consumptions, and a third of greenhouse gas emissions. In the past decade, the construction sector has responded to such concerns by focusing on post production energy efficiency. However, new findings indicate that upstream construction processes influence emissions significantly ? necessitating a shift in focus to include material choices and building processes.

Business Process Outsourcing : Vilka faktorer är avgörande vid ett beslut?

Outsourcing, förflyttning av funktioner till extern part som tidigare funnits i företaget, är ett fenomen som under de två senaste årtiondena har vuxit starkt i världen. Outsourcing har möjliggjort för företag att fokusera på sin kärnverksamhet och därmed erhålla konkurrensfördelar. Business Process Outsourcing är en kategori inom detta område, som innebär att företaget outsourcar hela eller delar av sin ekonomifunktion. Användandet av Business Process Outsourcing har ökat bland de svenska företagen under de senaste åren. Det finns mångtydiga förklaringar till denna framväxt, där en förklaring är att det är en trend.

Miljo?klassning inom infrastruktur och anla?ggningsprojekt : - en fo?rdjupning inom CEEQUAL

This thesis has evaluated environmental classifications of projects and the lessons learned to explore what the possible ramifications of implementing this in the construction and infrastructure are. Companies today are looking to develop methods to demonstrate their environmental commitments, but there is an uncertainty regarding the contribution of environmental classifications in this aspect.The literature review presents the theory of environmental classification, which provides a general knowledge of its function. The empirical data is based on an analysis of existing classification methods and qualitative interviews. The analysis shows specific environmental classification system for the area of construction and infrastructure. CEEQUAL is currently the only environmental classification applicable to Swedish projects and therefore serves as the basis for the continued analysis.

Komma ut. en kvalitativ undersökning av lesbiska och bisexuella kvinnors komma-ut-process

Syftet med denna kvalitativa undersökning är att jag vill beskriva och analysera homosexuellas komma-ut-processer. Datainsamlingsmetoden som använts är intervjucitat med kvinnor från den skrivna litteraturen, Lesbisk identitet, Dubbelliv och Komma ut, samt livsvärldsbaserade temaintervjuer med tre av mina vänner. I intervjuerna har jag utgått från dessa olika teman; upptäckt, resans gång och dagsläge. Jag har även med ett par citat från egna erfarenheter.Mina teorier jag har använt mig av är, Fuchs Ebaughs Exitprocess, Pennebakers begrepp Disclosure och Inhibtion, jag har även använt mig av interaktion, roll- och stigma inom socialpsykologi. Jag kommer att göra ett försök till att beskriva och analysera dessa områden inom mitt ämne; komma-ut-process i sin helhet, Vad är det som påverkar kvinnornas agerande i en komma-ut-process och hur personer i det sociala nätverket involveras i en komma-ut-process.

Olyckskorpen - finns han?

Detta examensarbete utreder frågeställningen om den såkallade "olyckskorpen" ? alltså yrkesarbetaren som är inblandad i flertalet arbetsplatsolyckor ? verkligen existerar. Frågan är lite av kontroversiell typ och har diskuterats sedan 1940-talet, utan något avsevärt utslag eller dokumenterat alster.Samarbetspartner blev NCC Construction och två av deras stora arbetsplatser i Stockholmsområdet valdes som mätfält; Söderby samt Frösunda.Undersökningen baserades på datainhämtning genom enkätformular till yrkesarbetare och ledning på de utvalda arbetsplatserna, genom erfarenhetsinhämtning från platschefer och lagbasar inom NCCs organisation samt från YTH-studenter på byggprogrammet. Författarnas egen erfarenhet från branschen har också vägts in i bearbetningen.Resultatet gav ingen olyckskorp att sätta fingret på, men en indikation från samtliga håll att egenskaper som kan knytas till olyckskorpen förekommer i branschen. Detta gav upphov till en teoretisk modell att användas för att ringa in olyckskorpar på individuell nivå i en vidare undersökning..

Ljudreducering av värmepump

This degree project handles acoustic measurements of the heat pump EcoAir 107, made by Enertech CTC AB. The sound from the three sound sources of the heat pump, fan, compressor and four way valve, have been measured to find out how they affect the total sound level of the product.Measures to attenuate the sound level have been developed and tested. By comparing these with the sound of the heat pump, in its original state, we have found out the measures which have best effects.The best attenuating measures came to be: taped openings and holes around the compressor space, isolating the top and the bottom of the whole construction, support of the fan bottom part and shielding of the sound source with a screen at a distance of 110 mmThese measures have been tested together and an average attenuation of the total sound level with 3,9 dB have been accomplished. In the front of the fan where the continuous sound is the strongest, the attenuation was 4,7 dB.This project is meant to be used as a guide by Enertech CTC AB:s during their future developing process..

Effektivisering av bygglovsprocessen. En kundundersökning i Göteborg

Bygglovsprocessen är en vital del i den totala byggprocessen eftersom ett bygglov är nödvändigt i nästan alla fall av nybyggnation och större renoveringar. I dagens samhälle där byggprocessen är under utveckling och allt större tidspress finns så är bygglovsprocessen ofta en flaskhals innan bygget kan påbörjas. Därför behöver bygglovsprocessen utvecklas för att bli effektivare.Syftet med denna undersökning att utreda vad tidigare kunder hos Stadsbyggnadskontoret (SBK) Göteborg anser om bygglovshanteringen. Utifrån de resultat som erhålls presenteras vilka delar i bygglovsprocessen som kan förbättras och effektiviseras. Dessutom ges förslag på förändringar för att uppnå detta.Kundundersökningen genomfördes med en enkät som skickades ut via e-post till kunder som fått godkänt bygglov i februari 2014.

Programvaruutveckling för en elektromagnetisk skanner med fokus på användaren, användarstudier och inlärning

The project was based on a request to improve an already existing program and hardware at the electrical engineering department at the royal institute of technology. For maximum ease of use, tests have been done on students to properly design the program for what it is meant to be used for. These tests have been transcribed and analysed, then brought back to the group in a discussion and then transcribed and analysed again, I call this process the ?four step process? (this process is presented and explained in chapter 6.4.). A part of this master thesis was also to analyse the four step process to enhance validity of this research.The project resulted in a new program with a new graphical view and features to help students and researchers to work with the technical tool for electromagnetic readings of planar objects.
