Regeringens transportinfrastruktursatsningar : En studie av tågtrafikens utrymme i regeringsanslagen för transportsektorn
In the government's bill on infrastructure for 2010-2021, the government presents that road investments should be prioritized before investments in the railway. The grants for operation and maintenance of the railways are much higher then in the last government's bill. Furthermore the current founding of investment in railways is higher then for road investment which is in opposite of the bill on infrastructure's directives. Therefore the purpose with my thesis is to find which factors that can explain how come the government has chosen to take these actions. As a model to help me achieve my purpose I have been using a modified version of the DBO-theory, where the basic factors to explain an action is Desire, Belief and Opportunities.
Metodik för fastställande av bärförmåga på befintliga betongkonstruktioner
Many buildings are now nearing the end of their service life. This applies to both the older houses from the 40's and 50's to the million project houses that did not prove to be as sustainable in the long run. Often there is a desire to extend the service lifetime, but to do that you need to make detailed inspections. The Folkets hus in Gävle is one of those buildings that is in need of renovation and to fulfill the new requirements that must be met in today's buildings. It is desired to make the buildings rentable space more attractive and to extend the building with two more floors.
Target Costing i produktutvecklingsprocessen : En studie på Volvo Construction Equipment i Braås
Bakgrund: Produktutvecklingsprocessen har på senare tid kommit att ses som en strategisk aktivitet som är avgörande för företagets överlevnad eftersom produktens utförande och kostnader till stor del fastställs innan tillverkning påbörjas. ?Target Costing? har sitt ursprung från Toyota i Japan och är en metod för strategisk kostnadsstyrning som har vuxit fram för att tidigt styra kostnader. Metoden används för att integrera kostnadsstyrning i produktutvecklingsprocessen i samstämmighet med kundkrav och företagets egna vinstkrav.Syfte: Syftet med studien är att beskriva och analysera hur ?Target Costing? används i produktutvecklingsprocessen på Volvo Construction Equipment i Braås för att ge kunskap till nya potentiella användare.
MON En mittpunkt i periferin
This thesis takes its starting point in the humanistic cultural-geographical concept of place, with the aim of achieving a greater understanding of what constitutes the place Mon today. Mon is located in the northwestern part of Dalsland. Until 1879, the area was described as outlying land, but with the extension of the railway between V?nern and the Norwegian border, Mon's station community emerged. In the mid-20th century, all activities in Mon were phased out, and since then, the place has been inhabited by only about 10 year-round residents.
Ebbas klänning Uppmätning och analys som källa till information i kombination med historisk undersökning
This study focuses on costume as a source of information. By making a case study of an 1880's dress itaims to explore the conservators potential as an investigator and conveyor of the information containedin a costume. Further explanation of this role is made by reference to several statements made by wellknown textile conservators. The paper also explores the different words used to make a new version ofa preserved or inexistant garment, gives an extensive presentation of taking patterns and an insight tothe other methods used for analysing costumes. The case study consists of an investigation of the dressconstruction, during which a pattern is taken, and a literature study of the contemporary fashion, theowner of the dress and the maker of the dress.
Passivhus, detaljutformning och dess köldbryggor
Along with rising energy prices and increasing awareness of environmental issues, the criteria for buildings energy performance have been sharpened through the years. Today, ?passive house? and ?low energy house? are commonly used phrases in the construction industry and is expected to become increasingly common in the future.For houses with well-insulated building envelope the importance of well constructed details increases when minimizing the heat losses. Examples of these details are floor-wall junction and window openings in the wall. In such connections thermal bridges occur, which means that heat more easily is transported out of the building, compared to the rest of the building envelope.This report deals with detail solutions around windows and a comparison between a traditional slab and a foundation from Koljern consisting of foam glass.
Försöksmetod för automatisering av kvalitetssäkring av SKB
Within all industries, there is a change in working time required; this also includes the construction sector. However, the way construction sectors are differentiated is by not having been given the opportunity to be practiced or tested. The aim of this thesis that we have done in collaboration with the Concrete Industry was to investigate the possibility of developing an automated method for quality assurance of SKB at the site. The idea is to make the O-funnel to be more utilized and therefore ensuring that the appropriate concrete quality is provided which eventually would lead to a better development in the production process.The project has involved theoretical work and laboratory experiments. The theoretical work gave us a good foundation at the beginning of the project. After gathering the information and material, the laboratory experiments began by SCC in their laboratory in Hammarby. The collected data from the various laboratory tests formed the foundation for trying to relate measurements for consistency of SCC with each other and therefore find out how measurements from O-funnel varies with different concrete mixtures.
Förbättring av U-värde i träkonstruktion för fönster med Aerogel
When constructing a building, a number of aspects must be harmonized in order for it to fulfill requirements ? a building must fulfill requirements such a load-bearing, conservation of energy and a good indoor environment by means of, among other things, moisture proofing .Moisture problems in buildings can affect health negatively. As we are increasingly staying in indoors, demands on a good indoor environment are higher.This work starts with examining moisture problems in slab-on-ground solutions, and then links the various scenarios to moisture problems in a concrete slab of a real building. The building with moisture problems is located in Årby by in Borlänge and moisture damage was found in the slab at an apartment adjoining wall.By reviewing literature written within the field of moisture problem, making hand calculations and modeling in the program Comsol Multiphysics, judgments are made to find explanations as to why the rise of moisture occurred in the building in Årby by.Generally, the following guidelines may be used to reduce the risk of moisture problems in slab-on-ground constructions:Drying of construction moisture before laying the floor material.Using draining layer beneath the slab, to prevent capillary suction.Using insulation under the slab, partly for comfort and to establish the temperature difference between the ground and the concrete slab.Avoid direct contact between the wood and concrete, due to degradation and fouling smells that normally occurs.If necessary, use additional vapor barrier.In addition to the above, there are various methods for moisture-proof and moisture-monitoring by design or by the method ByggaF suited for the entire construction process various events..
Relationen mellan utformningen av digitala bibliotek och användarnas behov. En intervjustudie vid Göteborgs universitets digitala bibliotek.
The aim of this thesis is to define digital library, and to investigate a relation between the construction of a digital library and user needs. The main questions to be answered are: 1 What criteria was used when constructing a digital library, particularly concerning issues like purpose, function, design, supply, services, resources and future development of the digital library? 2 How do the digital library system designers and system builders criteria correspond with those of postgraduate researchers? And what factors affect the use? A digital library is an enterprise that gives access to information stored digitally and directly available on the net. The crucial is that the enterprise has a control over collection of information and responsibility to make it available to a defined group of users. In order to investigate the relation between the construction of the digital library and user needs, I have interviewed five key people involved with the work with the digital library and twenty postgraduate researchers from the Gothenburg University.
Klistret i klustret : En undersökande studie av ansamlingen av GIS-relaterad verksamhet i Gävleregionen
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.
Virkesgripen, ett geometriskt verktyg :
The aim of this study was to investigate and describe conceptions that been used when people talks about grapples and to put together parameters that the customers sees as important when they chose a grapple from Hultdins.
Every year Hultdins manufacturer and sells about 3500 grapples around the world. With so many users its difficult to oblige everyone. To get an apprehension of what kind of grapple the operators wanted a formula with 18 questions was made. For the interviews 20 forestmachineoperators were choicest who had experience from Hultdins grapples, a lot of them also had experience from other grappleproducers and constructions.
The study showed that it is the durability the users give priority to.
Opera i Stockholm, Galärvarvet
Quality is the key to a well executed product or service. The construction industry hasn?t highlighted the quality in recent times which have contributed to the construction industry receiving much criticism in the field. The public sees it as an offhanded industry where errors and delays are common.The reason for this is considered to be primarily the lack of time, constant pressure to reduce costs and skills and the ability to communicate between the parties about what the correct quality really means. The industry has begun to realize that it must start setting clearer standards and that there are great opportunities for improvement.This report will give Peab an opportunity to develop their quality work.
Discourse analysis of the swedish integration politics
This essay is a discourse analysis of the integration politics of the different parties
in the Swedish parliament and the non-parliamentary party ?the Swedish
Democrats?, as it is presented on their respective web pages. The overall purpose
is to problematize and shed a light on how the current discourse(s) about
integration are constituted. Also of interest is how these construct our knowledge
and experience of the phenomena. We furthermore want to illustrate the social
consequences of such discourses on the construction and organization of identities
and groups, and, as a result, the courses of action that becomes available.
