  1. 21. Scann Loss Reduction on Phased Array Antenna

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

    Author : Wanyu Zhang; [2022]
    Keywords : Phased Array Antenna; Vivaldi Antenna; Scan Loss; Coverage Angle; Sub-array; Embedded Radiation Pattern; Fasad Array Antenn; Vivaldi Antenn; Skanningsförlust; Täckningsvinkel; Sub-array; Inbyggt strålmönster;

    Abstract : Phased array antennas with small size and light weight are proposed to make signal transmitting more efficiently and accurately. These antennas have such advantages that they can realize beam scanning over a large range, accurately track and identify targets within the observation range. READ MORE

  3. 22. The impact of snow loads on snow galleries : An initial evaluation of the snow galleries on the Iron Ore Line in Northern Sweden

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Karin Björnlinger; [2022]
    Keywords : Snow load; snow gallery; steel; FEM; railway; cobweb effect; utilizations grade; Snölast; snögalleri; stål; FEM; järnväg; spindelnätseffekten; utnyttjandegrad;

    Abstract : The snow galleries along the Iron ore railway line in northern Sweden have had major problems in recent years due to increasingly large snow loads. Despite great efforts reducing the loads by shoveling off the snow, several of the galleries have been damaged. READ MORE

  4. 23. Artificial Intelligence and Pattern Recognition Technologies for Cultural Heritage : Involvement of Optical Character Recognition Software for Citizen Science in the processes for Crowdsourcing of Ancient Italian Texts.

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

    Author : Julie Ballerino; [2022]
    Keywords : Artificial Intelligence; Pattern Recognition; Web-Technologies; Cultural Heritage; Crowdsourcing; Citizen Science; Optical Character Recognition; Accessibility.;

    Abstract : Cultural heritage makes reference to an extremely diverse set of sources. More specifically, historical artifacts as well as intangible elements of a community’s history, pertain to cultural heritage. However, when looking at the conservation, the enrichment, and the divulgation of these elements, the question becomes more complex. READ MORE

  5. 24. Exploring Column Update Elimination Optimization for Spike-Timing-Dependent Plasticity Learning Rule

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

    Author : Ojasvi Singh; [2022]
    Keywords : Spike-Timing Dependent Plasticity; neuromorphic computing; Hebbian Learning; Spiking Neural Networks; memory optimization.; Spike-Timing Beroende Plasticitet; neuromorfisk beräkning; Hebbiansk inlärning; Spiking Neural Networks; Minnes optimering;

    Abstract : Hebbian learning based neural network learning rules when implemented on hardware, store their synaptic weights in the form of a two-dimensional matrix. The storage of synaptic weights demands large memory bandwidth and storage. READ MORE

  6. 25. Precipitation behavior of the super austenitic stainless steel SANICRO® 35 and the effect on impact toughness and pitting corrosion resistance

    University essay from KTH/Materialvetenskap

    Author : Shunyi Li; [2022]
    Keywords : Super austenitic stainless steel; solid phase transformation; TTT diagram; impact toughness; critical pitting temperature; TC PRISMA simulation; Superaustenitiskt rostfritt stål; fastfasomvandling; TTT-diagram; slaghållfasthet; kritisk punktfrätningstemperatur; TC PRISMA simulering;

    Abstract : This research extended the knowledge of the solid phase transformation and the resulting influence on impact toughness and pitting corrosion resistance in super austenitic stainless steel (SASS) SANICRO® 35. A time-temperature-transformation diagram (TTT diagram) was assembled by performing isothermal heat treatments in the temperature range of 650-1050 °C for different periods of time, ranging from 5 min to 500 min.
