  1. 11. Millimeter-Wave Pencil Beam Leaky-Wave Antenna

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tom Eriksson; Erik Westberg; [2021]
    Keywords : Leaky-wave antenna LWA ; Continuous transverse stubs CTS ; Parallel plate waveguide PPW ; Dispersion;

    Abstract : Moving into higher frequencies, in occurrence withmodern applications, poses the issue of higher attenuation ofelectromagnetic waves, which in turn demand more directiveantennas. This paper proposes a directive antenna designoperating at 30GHz based on leaky-wave technology. Themodel consists of two main components. READ MORE

  3. 12. Optimization in Design of End-Bearing Concrete and Steel Piles with Regard to Climate Impact : Climate Conscious Material Choices in Early Project Planning

    University essay from KTH/Jord- och bergmekanik

    Author : Simat Adnan; Jann Ton; [2021]
    Keywords : Design; End-bearing piles; Bearing capacity; GWP; LCA; Climate change; Dimensionering; Spetsburna pålar; Bärförmåga; GWP; LCA; Klimatpåverkan;

    Abstract : Environmental sustainability is becoming more popular in the building industry. Sustainable thinking needs to be present during the whole construction process, from the idea phase to the final stages. READ MORE

  4. 13. Shear strength of prestressed concrete beams without shear reinforcement : A comparison between equations

    University essay from KTH/Betongbyggnad

    Author : Bawan Azad; [2021]
    Keywords : Shear force; prestress concrete; design provisions; Eurocode; carrying capacity; parametric study; concrete beam; Tvärkraft; förspänd betong; dimensioneringsbestämmelser; Eurokod; bärförmåga; parameterstudie; betongbalk;

    Abstract : A new version of EN 1992-1-1, Eurocode 2 for Design of Concrete Structures, is under development and one of the most discussed topics is shear capacity for prestressed concrete beams without shear reinforcement, partly because shear failure occurs suddenly and can have catastrophic consequences. For the new version of Eurocode, there are a total of three proposed equations to replace the two equations that currently exist in EN 1992-1-1 for shear capacity of prestressed concrete beams without shear reinforcement.

  5. 14. Monitoring energy efficiency of heavy haul freight trains with energy meter data

    University essay from KTH/Spårfordon

    Author : Philipp Geiberger; [2021]
    Keywords : Energy consumption; Energy meter; Energy monitoring; Heavy haul freight train; Key performance indicator; Multi-particle model; Simulation; Energiförbrukning; Elmätare; Energiuppföljning; Tungt godståg; Nyckeltal; Flerpartikelmodell; Simulering;

    Abstract : In this MSc thesis, it is investigated what parameters are relevant for describing energy consumption of heavy haul freight trains and how these can be used to develop key performance indicators (KPIs) for energy efficiency. The possible set of KPI is bounded by data available from energy meters used in electric IORE class locomotives hauling iron ore trains in northern Sweden. READ MORE

  6. 15. Lateral resistance of short piles near slopes - a review of calculation methods

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

    Author : Tomas Jönebratt; [2020]
    Keywords : Lateral load capacity; Horizontal load capacity; Piles near slopes; Approximate design methods; Soil; Geotechnical engineering; Friction soil; Wind load; Ultimate limit state; Noise screens; Technology and Engineering;

    Abstract : Vid konstruktion av bullerskärmar så väljs vanligtvis pålning som grundläggningstyp. Det finns flera modeller som kan approximera ett krav på minsta pållängd beroende på olika typer jordförhållande och vindlast. READ MORE
