"Underhållsfria fönster" : I vilken utsträckning är dagens "underhållsfria" fönster underhållsfria och hur ser man

AbstractThe aim of this examination paper is to get an overview on the ?no-maintenance? windowsthat exist on the Swedish market, like plastic and aluminium windows.By way of introduction the reader gets knowledge in the background and problemformulatethat this subject has. This introduction explains why it has become so popular to changeyour windows into plastic- and aluminium windows and there is an existing scepticismagainst PVC and aluminium as construction material for windows.The main part of this report is constructed by segments of interviews where bothproducers of windows and stakeholders gets to answer questions about their viewing onno-maintenance windows from a material and construction point of view and where theproduction is headed to in the future. This is followed by an evaluation of a questionnaireon how pleased the house owners that changed their old windows to no-maintenancewindows are, followed by an inspection of windows made up from wood and an aluminiumclothing, windows made from only aluminium and PVC-based windows. It ends with atheory part about the materials PVC and metal based upon facts included in literature.By reading this report you can draw the conclusion that no window can be entirely nonmaintenancebut that the materials PVC and aluminium still are good substitutes for woodto lessen the maintenance..

Återvinningsstationer på Lidingö : attityder och lokalisering

When the producers? responsibility for packaging was introduced in Sweden in 1994 the industry set up public recycling stations to facilitate the collection of the waste material. In order to establish recycling stations at suitable locations the municipalities assist the industry?s service organization for operation of the recycling stations, the Package and Newspaper Collection Service (Förpacknings- och tidningsinsamlingen, FTI). The objectives of this thesis are to improve the service of the public recycling stations within Lidingö town and to increase the accessibility to these stations for the inhabitants of Lidingö.

Försörjningens paradox : En kvalitativ studie om statliga företrädares framställning av våld i nära relation

The aim of this study was to examine how state representatives prepared domestic violence, regarding the economic consequences of women exposed to violence. In order to achieve a profound and comprehensive view of the governmental keyfigures discussion we performed five interviews and studied selected governmental preparatory works between the years 1995-2015. We used theory on social construction as an approach and certain themes were more regular in our empirical material, which we compiled in three different discourses. According to our empirical material the economic situation of women exposed to violence is caused by inequality and gender power structure. The solution given by state representatives are referred to the municipality and social services.

Vem styr bostadsbyggandet i Nacka och Södertälje? : Vilka aktörer påverkar slutresultatet?

Who runs the development? A comparative study of the construction of residential buildings in Nacka and Södertälje.The aim of this study is to identify actors involved in the initiation and implementation of residential house construction in two Swedish municipalities. This means who is taking initiative for new residential buildings, who affects the planning process, who finances these new buildings and who builds them. By exploring empiric material from the municipalities of Nacka and Södertälje, the above questions will be answered and by referring to pluralism, growth machine theory and regime theory a link to general theories of political science is made. The results found show that the analysed municipalities have quite different possibilities for acting and that these backgrounds are also important for which actors will take initiative for new residential buildings and which actors will be allowed to state their opinion during the planning process.

Är brottsoffret ett subjekt eller ett objekt? : En diskursanalys av brottsofferbegreppet

The purpose of this essay is to define the meaning of the concept of crime victim and how the crime victim as a concept is constructed. The question is answered through an investigation of the discourse that constructs and reproduces the crime victim. Furthermore the purpose is to open a theoretical discussion which aims to clarify whether or not the crime victim is a subject or an object through an examination of how the individual is constructed as a crime victim by the crime victim discourse.The essay takes a theoretical point of view based on a mixture of Michel Foucault?s and Ernesto Laclau & Chantal Mouffe?s discourse theories. The method used to organize the research ? regarding the meaning of the concept of crime victim ? is Laclau & Mouffe?s discourse analysis which is an extension and a part of the theory mentioned above.The discourse analysis creates a model of the crime victim discourse which answers the question of how the concept of crime victim is constructed, and how this concept should be understood.

Möjliga tillämpningar av BIM vid miljöcertifieringsarbete

In the construction industry today there is a significant technological revolution goingon. New methods for automated processes and information management are developedcontinuously. Intense studies are currently taking place to ensure ways and means toembrace the new technology of BIM.At the present, environmental certification systems are considered cumbersome andchallenging. However, the increasing demands of sustainable development in the constructionindustry imply that the environmental certifications will not disappear. ThisMaster Thesis examines the possibilities to apply BIM technology within the field ofenvironmental certifications to streamline the processes.The applications that provide the best opportunities are:- To use BIM to be able to, during the design stage, dynamically evaluate the resultor score a certain building will achieve.- To avoid unnecessary work through collection of data for calculations directlyfrom a BIM-model.- To be able to automate certain time consuming calculations that are currentlyperformed manually.- To automatically examine the completed model to ensure that the demands arefulfilled.The possibilities to use BIM within these areas are however limited by the technologyitself.

Värmeväxling med torkluft från Valmets pilotmaskin TM1 : Återvinning av spillvärme vid torkning av mjukpapper

Idag ställs stora krav på företag att vara miljömedvetna och resurseffektiva i sin verksamhet. Vid mjukpapperstillverkning används stora energimängder och inom industrin har det under många år funnits en strävan att energieffektivisera processer och att tillvarata spillenergi, bland annat genom värmeåtervinning. Valmet Tissue Technology Center i Karlstad har idag en pilotmaskinen utan värmeåtervinningssystem. Den här undersökningen gjordes i syfte att ta reda på hur stor återvinningspotentialen är för värmeväxling i pilotmaskinens torkpartier, bestående av Yankeekåpan och TAD-cylindrarna. Tre maskinkoncept undersöktes: DCT®, NTT? och TAD.

Bullerreduktion av hytt på Volvodumprar : Undersökning, mätning och analys

Too high levels of noise lead to various health problems and cost society billions of SEK peryear. In this thesis we have examined a model of the A40E articulated hauler at VolvoConstruction Equipment in Braås. We have tried to reduce cabin noise in an articulated hauler,while also providing a way on how to proceed with a machine when the cabin does not measureup to the sound requirement. The best way to find leaks were with a reference source of model4205 and its speaker HP 1001 from Brüel & Kjaer in the cab and then walk around and listen towhere the reference source was more prominent. In this way, we found that the edges and theplugs were sensitive areas.

Den svävande identiteten : En kvalitativ studie av identitetskonstruktionen i samband med debatten om det polska och turkiska medlemskapet i Europeiska unionen

This thesis aims to analyze the similarities and differences in how identity is constructed by the European Commission, the Council of Ministers and the European Parliament regarding the Polish membership and the potential Turkish membership of the European Union. The construction of identity is analyzed through a social constructivist perspective where identity is constructed by distinguishing ?us? from ?them?. The research metod used is a qualitative text analysis. The arguments of identity are taken from the Commission?s and the Council?s documents, as well as from the debates of the European Parliament.

Ny inmatningsfunktion för Arcomas detektorhållare

Arcoma is a company that develops and manufactures X-ray equipment for hospitals. One of the most crucial components is the digital detector. Due to the high cost it is made removable so it could be transferred and used in other X-ray apparatus. The detector is placed in a so called detector holder. The current detector has a rectangular shape which sometimes requires a 90 degree rotation to match the shape of the patient.

FÖRBÄTTRAD MONTERING OCH DESIGNAV BAGAGELUCKA

This thesis includes a mechanical engineering design work performed incollaboration between ÅF and Halmstad University. The work is done by FredyOlsson?s methods of Principle- and Primary Construction and David Ullman?stheories of Design for Assembly.The group was commissioned by ÅF to produce a concept to narrow down theassembly time of today?s luggage doors by reducing the numbers of adjustmentoptions. They also wanted it to be easier to mount the assembly by making itpossible to adjust the door in a closed position. Today luggage door takes, with its10 adjustment possibilities, around 4 hours each to assemble and ÅF wanted anassembly time around 10 minutes per door.Initially a preliminary study was made where the group began reviewing today'sconstruction and mounting of rails and doors on buses.

Design och konstruktion av Splitmaskin

During springterm 2010 Erik Persson and Magnus Hansson performed their ThesisWork with DIAB Laholm, in Hallands County for University of Halmstad.The project has been a product development project without exterior customers. Thusit had a great emphasis on functionality and less emphasis on marketing and such.This reflects the ambition to develop machinery to be used within the productionfacilities of DIAB Laholm, not to be sold to exterior customers.Main objective has been to create machinery which enables the production ofrotational symmetric work pieces within a NC-milling machine with 5 axles. Thework pieces milled will be made of DIAB?s material Divyncell with varyingdensities.The project has followed Fredy Olssons method involving Principal ? Primary ?Manufacturing constructions. However a complete manufacturing construction hasnot been made since DIAB just wanted a good Primary construction which will serveas a base for finishing touches at DIAB.By the end of the project material including calculations has been sent to DIAB andthey will finish the work and manufacture the machine if they find economic viabilityin this.The work method has been suited for this by several reasons, it was created withthese projects in mind and it?s also the method most familiar to us..

Studie av verkningsgrad potentialen för ett vatten baserat Waste Heat Recovery system med kolvexpander

SammanfattningEn ånganna monterades i EGR (Exhaust Gas Recirculation) slingan på en 12,7 liters Scania Euro V motor (DC1306). En modell som beskriver Rankine cykel togs fram med vatten som köldmedium i simuleringsverktyget GT-Power. Ångpannan i GT-power modellen kalibrerades m.h.a experimentell data.Simuleringarna visade att det optimala ångtrycket, det trycket där högst effekt kan erhållas från expandern, är beroende av EGR temperaturen. Det innebär att ju högre EGR inloppstemperatur desto högre optimalt ångtryck. EGR temperaturen i punkt 2 i ESC cykeln är 514? C för denna motor, vilket resulterar i ett optimalt tryck på 120 bar enligt simuleringen.
