Today more effective computer programs are in use, regarding design of geotechnicalconstructions. There is a risk that the theoretical background of the computerprograms, its limitations and the signification of the choice of soil parameter isforgotten when the computer programs become more user-friendly.This Master thesis deals with simulation and analysis regarding three computerprograms, FEM-design, with the addition Raft, Plaxis and BE-slab. Comparisons aremade for settlement and maximum moment in a concrete-plate. FEM-design is a threedimensional FEM-program, foremost created for design engineers. Plaxis is a twodimensional FEM-program, intended for geotechnical engineers while BE-Slab is aBoundary elements program in two dimensions that is mainly used by designengineers.
Kan ?Gnaget? och ?Stig-Helmer? påverka infrastrukturen? : En studie om turismens påverkan på infrastrukturen
The purpose of this paper is to examine whether, and if so, how tourism effect the construction of a new city district with a stadium in focus. The study is based on a case study of Swedbank Arena and Arenastaden as nearby area. There has been an interest from the writers to study Swedbank Arena and Arenastaden, as it is a current subject, and both of them are under construction, which means that it was possible to see how the process works from the ground up. It has been shown that Swedbank Arena is built up in an entirely new district in which there will be new infrastructure that is tailored to the stadium and the crowd it?s expected to attract.
Nödlösning i fickformat - stående kissande för kvinnor
The product "urinal funnel" for women has fascinated me for a long time. Not only because it solves a practical problem in a simple way, but also because it challenges our definitions of gender and behaviour. This report describes the process of making a new design for a funnel, taking material, ergonomics and construction in consideration. It also includes structuring a launching of the product in Sweden. It starts up with a large amount of information gathering, both by interviewing testgroup-perticipants, but also by researching and evaluating the range of existing funnels.

Modig eller rar, vad sa far? : En studie om Kamratpostens framställning av flickors och pojkars fritid
The aim of this study was to shed light on how journalists describe the child?s world and what gender labels are used in their descriptions. We wanted to get a better understanding of what happens when gender is constructed.In order to study how gender is constructed, we chose to examine how the children?s magazine Kamratposten describes children?s spare time. We chose Kamratposten because it turns to both girls and boys.
Lyftanordning för kraftuttag
This thesis has been developed inassociation with Strängbetong AB, Sweden.A few years backCementa AB introduced a new type of cement on the Swedish market: Byggcement,which is a Portland Limestone Cement. This type of cement is better for theenvironment and cheaper than Rapid Hardening Cement which is used today at SträngbetongAB.Strängbetong AB isvery interested in a change of cement in the factory and wants to know what ittakes to make a transition from Rapid Hardening Cement to Byggcement.This final projectaims at investigating how the workability and strength development are affectedby a transition from the existing cement to Byggcement and how we can change theproperties of the concrete by adding different types of superplasticizers. Laboratory and factoryexperiments were made, to investigate the transition..
Förbättring av leveranssäkerheten vid Volvo Construction
Equipment Components genom flaskhalsstyrning
Syftet med examensarbetet är att ta fram förbättringsförslag som höjer leveranssäkerheten för transmissioner och axlar vid Volvo Construction Equipment Components (CMP) i Eskilstuna. För att möjliggöra detta har en tydlig bild över företagets situation idag skapats. Enligt kunderna anser CMP vara en av de sämsta leverantörerna, vilket verifierades när den genomsnittliga leveranssäkerheten uppmättes till 30% i den utförda undersökningen. Den dåliga leveranssäkerheten är till stor del egengenererad och skapas genom en ond cirkel av länkade problemområden. Den onda cirkeln börjar med dålig leveranssäkerhet vilket medför svängningar i produktionen som förstärks genom sättet att planera och anskaffa material.

Effektivisering av lagringsplatser. Ett förbättringsprojekt på Mekpart AB
Aeroseum is an aviation museum located in an old military underground hangar. The ventilation system in the hangar is designed for the military purpose of the hangar. This design includes a solution with air flowing through the space between the construction of the hangar and the rock surface. The solution is intended to avoid a buildup of inflammable gases. This design leads too high humidity levels in the hangar.
Bättre arbetsberedningar med hjälp av BIM : Hur de kan utformas för implementering av BIM
During the past years Building Information Modelling (BIM), which is a digital way to work, has begun to spread amongst the parts of the construction process. At the construction phase the larger companies has started using the new way to work. This expansion has not been developed amongst smaller companies leading to the purpose of this report, to investigate in which ways the smaller companies can implement BIM by changing their way to work. The thesis is delimited to work preperations with the objective to define how the work preperations should be structured to enable the implementation of BIM. To achieve the objective of the report, information about the subject has been collected by interviews and literature studies.
De talar av erfarenhet : uppfattningar om begreppen demokrati och diktatur hos vuxenelever med utländsk bakgrund
I have in this study examined, through qualitative interviews, how adults with foreign background that are pupils in adult education in Sweden, understand the concepts democracy and dictatorship. Their expressed understandings have been compared with their former life experiences as well as with the aim of the social studies to create a qualitative understanding of essential social concepts. My starting point is theories about the adult in leaning processes. It has been assumed that the adult interprets the world much through former life experiences. I have also relied on the idea that having a qualitative, more scientific, understanding of essential subjects is important for the adult as a member of society and participator in the on-going political debate.
Passivhus - lönsamt eller ej? : En jämförelse mellan ett passivhus och ett konventionellt hus
As a result of increased energy prices more and more energy-efficient homes are coveted. An energy-efficient alternative is passive houses, which is characterized by an extremely well insulated building envelope that recovers the heat without the use of radiators or under floor heating. But a passive house requires a higher investment cost than a conventional building project, since it will require more construction materials, training of construction workers, greater land area, and long construction period. But the lower operating cost expects to pay back the higher cost of investment. We therefore question how profitable a passive house is in relation to houses built according to modern conventional building techniques.The aim of our study is to investigate the viability of passive houses compared to conventional houses.
Tidsstudier i kalvuppfödning :
Swedish agriculture stands in front of big changes the whole time. As a milking producer you have to adapt and develop the company to these changes and find the best solution. This potential is easy to find if you compare your company with other similar companies. Labour cost is the biggest cost in milking production after the cost for food. Today it is rather easy to measure how many hours per cow different system of cow houses needs, but we do not know so much about how many hours it takes to breed a calf.
To learn more about the labour time with the calves during the first time after the calf was born, I made time studies on five different farms with calf hutches, automatic milk system, large calf boxes, and smaller calf boxes with teat buckets.
Varför BIM?
Is the new technology always the best? This final project tries to determine if BIM is the melody of today, or if traditional 2D drawing is recommended. Perhaps a compromise is necessary, utilizing both methods.In order to answer this question, different views from the industry have been retrieved through reports, producers of software and users. The approach has consisted in building a 3D model of the school Råslättsskolan, house 01, along with interviews with people involved in the building process.When working in 2D it is hard to include the third dimension, mistakes are done and collisions happen that must be corrected, in most cases at the construction site. BIM is an incredible help since the model allows you to detect collisions and correct them.
I regnbågens skugga : En analys av kommuners diskurser kring våld inom hbt-relationer
The purpose of this study is to investigate how the Swedish municipal welfare system, in their capacity as discourse makers, construct Intimate Partner Violence (IPV) in the relationships of Lesbian, Gay, Bisexual and Transgender (LGBT) people. A discourse analysis of their official plans of action regarding IPV and the information directed towards their citizens through their webpages showed that the discourse surrounding IPV revealed a gender dichotomy, where the victim was mainly constructed as being female and the perpetrator as male. As a consequence of this, gay and bisexual men were rendered invisible from the discourse surrounding victims of IPV, although they could be included in the construction of perpetrators of it. Lesbian and bisexual women were often included in the understanding of victims of IPV, but in the discourse surrounding perpetrators of it they were made invisible. The discourse about IPV also excluded the experiences and vulnerability of people who identify as being transgendered.
