  1. 21. Dynamic analyses of hollow core slabs : Experimental and numerical analyses of an existing floor

    University essay from KTH/Bro- och stålbyggnad

    Author : Markus Hansell; Panagiotis Tamtakos; [2020]
    Keywords : Hollow core slab; Structural dynamics; Signal analysis; Mode shape; Frequency response function; Complex mode; FE-model; Håldäcksbjälklag; Strukturdynamik; Signalanalys; Modform; Frekvenssvar; Komplex mod; FE-modellering.;

    Abstract : For intermediate floors in residential and office buildings, as well as in parking garages and malls, there is a wide use of hollow core concrete slabs in Sweden today. Hollow core slabs are precast and prestressed concrete elements with cylindrical-shaped voids extending along the length of the slab. READ MORE

  3. 22. Multilateration in Direct ShortRange Communications Networks : Utilising Basic Safety Messages and Received Signal Strength Ranging

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Author : Andrew Galbraith; [2020]
    Keywords : DSRC; trilateration; multilateration; RSS; V2X;

    Abstract : Traditional satellite positioning systems have limited resolution and have proved inaccuratein areas such as urban canyons where signals are subject to bounce phenomena or indeed may be entirely unavailable. An alternative method of positioning is that of tri/multilateration, which uses known positions and distances from beacon points to locate a receiver. READ MORE

  4. 23. Heavy vehicles: Load variation and scatter

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Patrik Hård; [2020]
    Keywords : Load variation; Pseudo-damage; Scatter; Wheel configuration; Belastning; Variation; Hjulkonfiguration; Pseudo-skada;

    Abstract : This master thesis studies accelerations recorded and stored onboard Scania trucks. From these accelerations, a general load (𝐹 = 𝑚∗ 𝑎) description is deduced. In the next step, an abstract number, ‘pseudo-damage’, representing the load’s fatigue damage potential is calculated. READ MORE

  5. 24. A Numerical Analysis on the Effects of Using CO2 as a Driving Fluid for a Geothermal Plant

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : David Bennich; [2020]
    Keywords : reinjection; two-phase flow; geothermal energy; CO2 sequestration; iTOUGH2; ECO2N; återinjektion; tvåfasflöde; geotermisk energi; koldioxidlagring; iTOUGH2; ECO2N;

    Abstract : To limit the effect of global warming society needs clean energy sources and to reduce emissions of greenhouse gases into the atmosphere. By combining carbon capture and storage technologies together with geothermal power production it is possible to gain fossil free energy while potentially storing CO2 at the same time. READ MORE

  6. 25. Acoustic Source Characterization of a Road

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Somayan Basu; [2020]
    Keywords : Acoustic Characterization; Road noise; Point Source; Line Source; Traffic Intensity.; Akustisk karaktärisering; vägbuller; punktkälla; linjekälla; trafikintensitet.;

    Abstract : A road can be considered as a noise source based on its traffic density. Intuition says, a road, with closely spaced vehicles, can be classified as a line source and for sparsely spaced vehicles, a collection of point sources. READ MORE
