Jämförelse mellan olika material i spåröverbyggnadens bärlagerbärighets- och materialprovning av spårväg i Göteborg

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Förbättrad styrning av ingående material

Detta arbete har syftat till att undersöka möjligheterna till förbättring av material- och produktionsstyrning vid Sandvik Mining and Construction i Sandviken. Målet har varit att skapa ett underlag för förbättrad styrning av ingående material. Nulägesanalysen visade att förbättringspotential fanns inom klassificeringen av hårdmetallämnen och komponenter. Dessutom var det önskvärt att ett kanbansystem uppfördes på de förslipade hårdmetallstiften som går till den helautomatiska STAMA-cellen. Examensarbetet har gett underlag för en omstrukturering av denna klassificering men även för en framtida uppdatering av den.

Volvos Utvecklingsverkstad : En studie i färgteori och inre miljöer på verkstadsplatser

Den här rapporten avhandlar arbetet med att ta fram ett förslag som förlänger Volvos kärnvärden - kvalitet, säkerhet och miljöhänsyn, ut i Utvecklingsverkstaden på Volvo Construction Equipment, Hauler Loader Business Line, i Eskilstuna. Förslaget är utformat som ett koncept, som ska kunna överföras till andra verkstadsmiljöer på Volvo, om så önskas. Idéförslaget har baserats på en studie av den befintliga Utvecklingsversktaden. En modell av verkstaden i skala 1:50 utformades som presentationsmedium.Vid examensarbetets slut har förslaget presenterats och utvärderats av målgruppen. Den primära målgruppen har varit de anställda på avdelningen.Slutsatserna av arbetet är att en informationsbärande interiör kan formges för att representera ett företags kärnvärden och visa på innovation och framtidstänk.

Byggnadslogistik i infrastrukturprojekt för effektivare användning av grävmaskiner

Detta examensarbete har utförts på högskoleingenjörsprogrammet för Byggteknik och Design vid Kungliga Tekniska Högskolan i samarbete med Svensk Bygglogistik AB. Arbetet diskuterar betydelsen av byggnadslogistik i ett infrastrukturprojekt för att uppnå en högre utnyttjandegrad för grävmaskiner med stöd av logistiksamordningsverktyg.Sammanlagt har 2150 mätningar utförts under två veckors tid för att kartlägga utnyttjandegraden för en bandgrävare (EC250CL) och en hjulgrävare (Atlas 1505M) på ett referensprojekt i Stockholmsregionen. Resultatet har sammanställts separat för de olika resurserna genom att redovisa och analysera andelen outnyttjad tid och de bakomliggande orsakerna till den outnyttjade tiden.Resultatet visar att utnyttjandegraden för bandgrävaren är 53 % och 59 % för hjulgrävaren vilket tyder på att ett förbättringsutrymme finns.Avslutningsvis diskuteras rekommendationer för hur användning av logistiksamordningsverktyg kan utökas inom anläggningssidan..

Shamyana, the out door pleasure

The present work is a continuation of the ideas developed in previous projects during my Masters studies that explored the relation between pattern, form and space. Starting from the pattern multiplication for space construction the present project proposes textiles as an assortment of flexible expressions. The purpose of the project is to explore aesthetic and functional potential of textiles for out door temporary structures. This is to create a pattern interface which filters sunlight through a textile surface to offer instant sheltering solutions for out door activities. The project combines research and analyses of outdoor temporary structures and scope of textile in the area.

En smak av svensk manlighet : Ideal och värden i sportdrycksreklam

The society of consumption exposes us to a lot of information, where advertisement constitutes an extensive part. Due to its expanding, advertisement receives a natural and obvious space in our everyday life. This study aims to investigate how social and cultural values can be mediated in advertisement. The focus has been put to ideas related to health and fitness in the advertisement of power drinks. The thesis takes social constructionism as a starting point, and combines image- and critical discourse analysis in purpose to analyze the pictures.Sociology of consumption, construction of identity, lifestyle and everyday life all constitute an essential part of my analysis.

Det dynamiska genuset. : En teorikritisk studie av hur genus görs i de religiösa texterna Ramayana och Ruts bok

Den här studien använder sig av en queerteoretisk utgångspunkt för att försöka reda ut vad som kan sägas om genuskonstruktionen i två välkända religiösa berättelser: den hinduiska Ramayana samt Ruts bok som återfinns i den hebreiska bibeln. Studien använder en hermeneutisk metod och en queerteori med teoretiska modeller av Judith Butler och Yvonne Hirdman. Det kan ses i båda berättelserna att genuset hos både manliga och kvinnliga karaktärer ändrar sig under berättelsens gång, flera gånger och i relation till varandra. Slutligen diskuteras resultaten och det visar sig att den teori som används i uppsatsen, queerteori, saknar en förståelse för det slags dynamiska genus som finns att se vid en läsning av Ruts bok och Ramayana..

Nätet spinns vidare : Hur används Internet i ungdomsromanen?

The essay is a text centred study of ten Young Adult Novels, in which Internet plays an essential part. The structure is put into light out of used narrative techniques of how to create stories and its construction elements. I compare the ten Young Adult novels to each other. My aim is to analyze the functions of the Internet motive in the chosen novels, using different approaches, and enlighten it with concerns to the new phenomenon that Internet is in society. Consequently the essay will also have a mimetic touch to it.The ten novels that I base the analysis on are written of both med and women and have both male and female as main fictive persons, and are from different parts of the world.

UTANFÖRSKAP I ETT MAJORITETSSAMHÄLLE : En diskursanalytisk studie med fokus på romerna i svenska tidningar

In this paper I study how the minority group Roma appears in the Swedish media. I also look at possible similarities and differences in appearance before and after the disclosure of the Roma registration by the Swedish police in September 2013. To answer my purpose with the paper I treat the following questions:How is the minority group Roma constructed in the media before and after the disclosure?In which ways are the minority group Roma expressed in the media before and after the disclosure?I am using a discourse analytic method based on theories of construction between ?them? and ?we? and the media?s impact on social constructions and identities. By analysing twenty-eight articles from a period of one month before and one month after the disclosure the result shows that there are more similarities than differences between how the Roma are described in the Swedish media.

Urban Vindkraft : ett nytt element i bebyggd miljö?

This paper aims to explore the phenomenon urban wind energy, its visual effect on built environment and the factors that affect the opinion towards new elements in the city. A place study of the city Gävle serves as a complement to the theoretical part of the paper. The theoretical discussion opens with an account for the technical and economical conditions of urban wind energy. It presents the technical basics, different types of turbines and a discussion occurring wind related techniques in built environment. Today, the knowledge of how the wind moves and acts in the rural landscape is quite good.

The purpose of this study was to build a database for point-bearing piles in dense noncohesive soil, predominantly moraine. Further, the database was analysed and areas with difficult geotechnical conditions was identified.The database includes for point-bearing piles driven to refusal in moraine. Piles with mainly shaft friction have been excluded. Only concrete piles have been included. Geographically the database covers almost all geotechnical conditions of Sweden.

Incitament för förbättrat miljöarbete. En studie av miljöarbete I relationen mellan beställare och entreprenör

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Degenerering av varumärken: - en juridisk konstruktion eller ett marknadsföringsproblem?

Degeneration of trademarks - a legal construction or a marketing problem? This paper discusses the issue of degeneration of trademarks. The study has its starting point in the conflict that may arise between the principles of marketing and the legislation concerning IP rights and market law. In this study several verdicts are studied in which degeneration has been addressed. Analyzing these rulings as well as the current legislation in the light of marketing theory, a conflict between marketing and legislation can be noted.

Energideklaration och energiförbrukning för småhus och flerbostadshus

Energy is today a very common topic, not only in Sweden but in the whole Europe. In EU they have given out a directive 2002/91/EG about buildings energy use and throw this they have forced their members to show how much energy their buildings use. In Sweden has the gouvernment established a law (SFS 2006:985) about energy declaration for buildings which demands that the building owner needs to show how much their buildings energy consumption are. Important to know is that this law doesn´t applies for industrial buildings.The report will show what the new law about energy declaration for buildings and appurtenant directions will mean for Riksbyggen. Also energy calculations will be done to be able to compare Riksbyggen buildings with the new law and directions.
