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.
Identifiering och uppföljning av dagliga fel och brister på byggarbetsplatsen : Samt hur dessa kan hanteras enligt Lean-koncepttänkande
Byggbranschen brottas idag med en hel del fel och brister i byggprocessen. Exempel på problem är bl.a. höga byggkostnader, kvalitetsbrister samt att det förekommer slarv och okunskap. Produktiviteten i byggbranschen har inte utvecklats lika mycket som i tillverkningsindustrin som använder sin ledningsfilosofi Lean Production.Syftet med detta examensarbete är att få insikt i vilka vanliga fel och brister som förekommer i byggbranschen, samt att kunna ge förslag till förbättringar i enlighet med lean-tänkande. När man talar om Lean i byggsammanhang benämns det Lean Construction.
Vasastaden och gentrifieringsprocessen 1970-2010
Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.
Kvinnoföreningar - rörelser för kulturöverskridande möten och social inkludering
This is an interview based qualitative case study on two Women's Migrant Associations in Malmoe, which I interpret as being part of a women's movement, with characteristics of a new social movement. The aim of this study is to get a deeper understanding on how the collective identity is being constructed, in this women's movement where the membership is not based on an exclusive ethnic identity.I make a two dimensional analysis that departs from a social constructivist underpinning, including the theories Transversial Politics, Postcolonial feminism and New Social Movement Theory.First I analyze the construction of collective identity from the external social and cultural context, and get confirmed that the collective identity of the movement is based on a common experience of social exclusion and a plurality of actions that aims to fight the structural injustices based on gender and ethnic discrimination. Secondly I analyze how the collective identity is being constructed and maintained from the interactions between the members of the movement, from an understanding of Transversial Politics. My findings show that the members of the movement interact in a participatory democratic way which generally corresponds to Transversial Politics. According to Transversial Politics this can lead to a construction of an empowered inclusive collective identity for the members and as my empirical study confirms it also means possibilities for deconstruction of boundaries between social groups..
Ett tillvägagångssätt för minskad variation i monteringsprocessen av en prefabricerad betongstomme
Att leva med kronisk sjukdom påverkar personen och dennes liv på många olika sätt. Vardagen kan upplevas oförutsägbar och aktiviteter kan behöva anpassas efter tillståndet. Kronisk obstruktiv lungsjukdom (KOL) är en irreversibel och progressiv sjukdom som förutspås vara den tredje största dödsorsaken i världen år 2030. Syftet med denna litteraturstudie var att beskriva upplevelsen av hur det sociala livet påverkas hos personer med KOL. Arton kvalitativa vetenskapliga studier analyserades med kvalitativ manifest innehållsanalys.
Den mångskiftande mångkulturalismen : En kritisk diskursanalys av mångkulturalism i bibliotekskontext utifrån ett intersektionellt etnicitetsperspektiv
The purpose of this thesis in Library and Information Science (LIS) is to examine concepts related to multiculturalism in Sweden. It aims to look beyond the rhetorical construction of these concepts, in an attempt to clarify the actual purpose of commonly emphasizing the importance of mulicultural library services. Norman Fairclough's critical discourse analysis (CDA) as well as theories on ethnicity and intersectionality constitute the theoretical frame. The material consists of selected anthologies, handbooks and articles in Biblioteksbladet from 1974?2014, as well as a small case study.
Standardisering av bakpanel.
HAFA Bathroom Group has given us the assignment to develop a standardized back panel for their bathroom cabinets. This cabinet is going to be applied to most of their current and future cabinet solutions. To this point, they have constructed unique suspensions-and back panels for most of their cabinet models. They have also been forced to pull wiring and assemble the cabinets differently because of factors like; position of the wall sockets, dimensions of the cabinets and their shapes.The company wants to distance themselves from their current solution, firstly because the cost of having manpower to design each individual suspension solution, secondly because they will save a lot of money when the manufacturing process requires a minimum of components to be constructed. As a result of this, the company can use their resources better to develop future products.The main idea is that the consumer isn?t required to change the suspension or back panel when they decide to buy a new cabinet.
Jämförelsestudie för tre olika metoder att beräkna genomstansning i betong : Skillnader i genomstansningskapacitet för metoderna i BBK04, EK2 och BHB
Before the European construction standards were introduced in January 2011, it was mainly themethod in BBK04 that was used for calculating punching capacity in concrete structures, and in lesscommon cases the method in BHB. The method of BBK04 is easy to use and have had the samestructure since the first was published in 1979. The Concrete handbook method (BHB) where usuallyonly used when a higher punching capacity was needed and the cross-sectional height where fixed,calculations using this method entails more work, but will in return usually give a higher capacity. Italso allows the use of shear reinforcement to increase the cross-section capacity. The method ofcalculating punching shear in EC2 differs largely from the methods of BBK04 and BHB.
Utbyggnad Av Eriksberg
During the years of development in the 60s and 70s the need for new housing in Sweden arose. Sweden was going to be the most modern country in the world. This period has later been called ?the time of the big programmes?. One of the parts in this building of a welfare society was a large policy of building politics with few counterparts in history.
Bristfällig tillbudsrapportering : En sammanställning av attityder och kunskap kring tillbud inom Peab
The construction industry stands as one of the industries in Sweden where most employees tend to encounter accidents. At the same time, the Swedish authority of work environment estimates that there are large numbers of hidden statistics with accidents and incidents that never gets reported. To prevent accidents, the Swedish authority of work environment has decided that every company have to, beside report every accident and major incident to the authority of work environment, keep statistics and evaluate every incident that happens at their places of work.The people responsible for work environment at the Swedish building contractor Peab, believe that it is only a fraction of all incidents happening at their construction sites that actually gets reported. The purpose of this study is to investigate the reason why employees of Peab do not report incidents. By an inquiry and interviews with both craftsmen and office holders at Peab Bygg Öst 1, the employees? attitudes and knowledge have been studied and evaluated.The study shows that the craftsmen´s knowledge of incidents is relatively low.
Hantering av orderinformation i tillverkande processer: En studie på Atlas Copco Construction Tools
Globaliseringen och den ökade konkurrensen ställer större krav på företagen vilket har medfört att arbetet med logistik har utvecklats från att enbart förknippas med transporter av varor till att idag förknippas med effektiva flöden inom hela försörjningskedjan. Flödena inom försörjningskedjan består av material-, betalnings- och informationsflöden, där det finns en stark koppling mellan alla tre. En väsentlig skillnad mellan de tre flödena är att materialflöde och betalningsflöde representerar kapitalbindning i motsats till informationsflöde som inte hanterar ett direkt ekonomiskt värde. Det bidrar ofta till att informationsflödet förbises i effektiviseringsprocesser. Eftersom ett informationsflöde kan stå för avgörande indirekta värden är det en viktig pusselbit för att försörjningskedjan skall kunna nyttja sina resurser optimalt.
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.
Implementering av Virtual Design and Construction: en
fallstudie av Veidekke Entreprenad AB
Den svenska byggbranschen står i nuläget inför en stor teknisk förändring, införandet av Bygg-informationsmodeller(BIM)/Virtual Design and Construction (VDC) i stor skala. Branschens olika aktörer ser olika vinster med implementeringen som kommer påverka hela byggprocessen, från projektering till förvaltning. Denna studie fokuserar på organisation och process i projekteringsskedet och grundar sig på en fallstudie av Veidekke Entreprenad AB. Företaget har implementerat VDC i delar av organisationen och i nuläget, efter lyckade pilotprojekt, utvidgas satsningen och implementering görs i större skala. Studiens syfte är att kartlägga Veidekkes VDC-mål och strategier, för att därefter studera process och organisation i projekteringsfasen och hur de bör utvecklas för att skapa goda förutsättningar för att VDC-målen ska kunna uppfyllas.
Brandsäkerhet i ett småhus
This essay includes the planning and designing of a house as well as writing a rapport about howto increase fire safety in small buildings.More than 6000 homes burn in Sweden every year (Brandskyddsföreningen, 2012c). Thedevastation and the costs are usually very high. This report examines possible measures to reduceboth personal injuries and economic losses resulting from house fires in small buildings.Swedishbuilding regulationsplay a major role when it comes to constructional fire safety. However therequirements inSwedish building regulations are very low for small buildings and this is anargument for raising the requirements.The report shows and describes possible methods to build safer with regards to fire in terms ofmaterials and different building structures. Major focus has been on fire cells but other solutionsare also examined and described.
Som om min kropp inte är min...: Bilden av unga kvinnors sexualitet i svensk ungdomslitteratur
The purpose of this Masters thesis is to examine how young womens sexuality is described in Swedish youth novels. The analysis is based upon eight books of which four were published during the period from 1970 to 1975 and four books were published during 2000 to 2005. The theoretical framework is based on a gender theoretical perspective where Yvonne Hirdmans theories about a gender system and Ylva Elwin-Nowaks and Heléne Thomssons ideas about gender construction are crucial. Also Anthony Giddens theories about sexuality in the late modern society are used, where the plastic sexuality and the pure relationship are central ideas. The method is based upon textual analysis, and a model of analysis is constructed with its basis in the theoretical attempt.
