    University essay from Linköpings universitet/Matematiska institutionenLinköpings universitet/Tekniska fakulteten

    Author : Marianne Söderholm; [2018]
    Keywords : Water waves; stream solutions; dispersion equation.;

    Abstract : This thesis concerns the water wave problem corresponding to a piecewise constant vorticity function. There are several results connected to this field. READ MORE

  2. 2. Modelling and simulations for analysing thermal performance enhancement in air ducts with cold surface and hot air

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper

    Author : Olle Rosell; [2018]
    Keywords : Heat transfer; air-duct; simulations;

    Abstract : The world today has large challenges in order to manage a changing climate and the consequences that the climate change has on the environment and human living standards. This climate change is largely affected by the emissions of greenhouse gases, which come from usage of fossil fuels. READ MORE

  3. 3. Quantitative Risk Assessment of Wave Energy Technology

    University essay from Uppsala universitet/Elektricitetslära; Uppsala universitet/Elektricitetslära

    Author : Emil Ericsson; Eric Gregorson; [2018]
    Keywords : risk assessment; wave power; wave energy converter; marine energy technology; failure rate; Monte Carlo; fault tree; CAPEX; OPEX; LCOE; vågkraft; vågenergi; riskanalys;

    Abstract : European Commission (2011) aims to reduce the greenhouse gas emission sby 85-95% by 2050 in comparison to 1990’s levels. Wave energy could be an important step to archiving this goal. This report aims to develop a quantitative risk assessment for the Uppsala University's wave energy converter. READ MORE

  4. 4. Numerical investigation on the effects of out-of-flatness on leakage in metal-to-metal seals

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Lumi Canhasi; [2017]
    Keywords : ;

    Abstract : Since the usage of pressurized systems, there has been a challenge to prevent and control leakage of different fluids. When a metal-to-metal face seal is designed, different aspects are to be considered. Its ring shaped sealing surface is designed to prevent leakage and also to maintain pressure. READ MORE

  5. 5. Reflection, absorption and filtering of ground vibrations, A study in the use of different arrays of cylinders to attenuate and filter ground vibrations

    University essay from Chalmers tekniska högskola/Institutionen för bygg- och miljöteknik

    Author : Alexander Sandercock; [2017]
    Keywords : Vibrations; reflection; absorption; ground; acoustics; dynamics; rayleigh; waves;

    Abstract : With the increased rate of urbanization comes an increase in disturbing ground vibrations. These can be produced by building operations, different kinds of traffic and in some cases mining and military operations. It is therefore necessary to try and reduce the amplitude of these disturbing, and in extreme cases damaging vibrations. READ MORE
