Analys och förbättring av en mätenhet för laddning av elfordon

Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.

Plastfilmsöppningar till Tetra Paks förpackningar : En teknisk introduktion och tidig konceptutveckling

This master thesis is an early concept development project about using plastic films and sheets as materials for shaping openings for Tetra Pak packages. It is also a technical introduction highlighting the areas of importance for the development of plastic film and sheets openings. The master thesis has been carried out as a co-operation between Chalmers University of Technology, KTH Royal Institute of Technology and Tetra Pak AB.The master thesis study presents an introduction that gives an understanding of the technical complexities and design possibilities of using thin plastic films and sheets in liquid carton openings. The knowledge is then transferred into five design concepts which points out the areas of opportunity. The technical introduction is widespread and extensive covering current packing trends, the liquid carton package and openings, thermoplastic material properties, and thin film and sheet manufacturing and shaping.

Maybe it would be better if I was Swedish: En studie av internationella mastersstudenter i Sverige och deras utmaningar och m?jligheter p? arbetsmarknaden

Recent changes in Swedish law suggest new groups of ?desired? labor migrants, which international students is an example of. Despite this, international students in Sweden have received little previous attention in the literature. The current study focused on international master students? experiences of job searching in Sweden and challenges they face in job searching, recruitment, and workplaces.

BIM som en effektivisering av processindustrin ? en fallstudie på COWI Management AB

Building Information Modeling eller byggnadsinformationsmodellering används idag inom byggbranschen för att effektivisera projekteringsprocessen. Denna metod är fortfarande relativt ny inom branschen men är på väg att bli en branschstandard. Indikationer som visar på detta är att på universitetsutbildningarna Byggnadsingenjör och Affärsutveckling och entreprenörskap inom byggsektorn vid Chalmers tekniska högskola läggs stor vikt på utbildning om BIM. Många branschtidningar behandlar även detta ämne. På teknikkonsultföretaget COWI Management AB finns intresset av att se vilka möjligheter BIM-metoden kan medföra och om metoden går att överföra på processindustrin.Syftet med examensarbetet är att tydliggöra innebörden av BIM-metoden.

Beräkning av ASME-flänsar enligt EN-standard

In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.

Samspel i det offentliga rummet : en studie av Shared space inverkan på trafiksäkerhet, tillgänglighet och attraktivitet i det offentliga rummet

Inom stadsplanering har vi sett att kvaliteten i det offentliga rummet har minskat under det senaste århundradet. Under 1960-talet utvecklades det, exempelvis, i Sverige en modell för stadsplanering med hänsyn till trafiksäkerhet, SCAFT (Stadsbyggnad, Chalmers, Arbetsgruppen för trafiksäkerhet), som strävade efter separering av de olika trafikslagen. Trafikseparering av de olika trafikgrupperna medförde samtidigt separering av funktioner och sociala företeelser i det offentliga rummet. Det gjorde att städerna präglades av rum avsedda för transport och inte för social interaktion med vackra och inbjudande platser att vara på. En motsatt modell har däremot utvecklats i andra länder i Europa.

Utredning av grundavlopp på broar

AbstractIn the fall of 2003 a project was started in the Swedish building sector that is called BASTA (the building sectors’ termination of especially harmful substances). The project is operated by the building companies NCC, Skanska, PEAB and JM, the Swedish Building Industry and the Swedish Environmental Institute IVL. The purpose of the project is to create a common environmental assessment system for the entire building industry and with the help of this system phase out the use of especially harmful properties from building products.In a large sense BASTA works like this; On the BASTA web site there is a database, to which a supplier can register the company and the company’s products. Only those products with a substance content that fulfil the demands of the BASTA system, is to be registered. As it is the supplier himself that carries out the registration of the company and the company’s products to the system, the BASTA-organisation annually controls that the companies that are registered in the database, fulfils BASTA’s demands.Since NCC is one of the companies that operates BASTA, BASTA is probably going to be the environmental assessment system that is recommended for the company in the future.
