  3. 2. Moving towards a proactive sewer pipe inspection approach : A state-of-the-art analysis

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ataul Hakim Mahamud; [2023]
    Keywords : Sewer failure; Inflow; and infiltration; CSO; Blockage; prediction model; proactive; Avlopps Fel; Inflöde och infiltration; CSO; Blockering; prediktionsmodell; proaktiv;

    Abstract : The failure of sewer pipes is a significant issue that can adversely affect the environment and public health. The problem is exacerbated by the additional burden it places on treatment plants, which must work harder to process the increased sewage flow resulting from pipe failures. READ MORE

  4. 3. Personalized Federated Learning for mmWave Beam Prediction Using Non-IID Sub-6 GHz Channels

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

    Author : Yuan Cheng; [2022]
    Keywords : Personalized Federated Learning; Millimeter wave; Beamforming; DeepMIMO; Non-IID; Personaliserad Federad Inlärning; Millimetervågor; Strålformning; DeepMIMO; Icke-IID;

    Abstract : While it is difficult for base stations to estimate the millimeter wave (mmWave) channels and find the optimal mmWave beam for user equipments (UEs) quickly, the sub-6 GHz channels which are usually easier to obtain and more robust to blockages could be used to reduce the time before initial access and enhance the reliability of mmWave communication. Considering that the channel information is collected by a massive number of radio base stations and would be sensitive to privacy and security, Federated Learning (FL) is a match for this use case.

  5. 4. Structural features underlying antigen presentation by the non-classical MHC class Ib molecule Qa-1b

    University essay from KTH/Proteinvetenskap

    Author : Lejla AI-Tamimi; [2022]
    Keywords : immune checkpoint; NKG2A; MHC class Ib; Qdm; antibody; crystal structure;

    Abstract : Blockering av NKG2A receptorn på NK - och CD8+ T celler med en anti-NKG2A antikropp, medför en aktivering av cytolytisk aktivitet, och är en lovande immunkontrollpunkt i immunterapi mot cancer. Nyligen har en TCR-liknande antikropp, EXX1, som binder till liganden för NKG2A receptorn, Qa-1b - en icke-klassisk MHC klass Ib molekyl i möss -studerats i tumör modeller in vitro. READ MORE

  6. 5. Analysis of High and Low Rossby Wave Phase Speed Events Over Northern Mid-Latitudes

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

    Author : Emma Rosengren; [2022]
    Keywords : Rossby waves; phase speed; atmospheric blocking; storm track; windstorms; Rossbyvågor; fashastighet; atmosfärisk blockering; lågtrycksbana; vindstormar;

    Abstract : The large-scale, mid-latitude circulation in the upper troposphere is dominated by Rossby waves. The jet stream flows along the wave structure and surface cyclones can be found ahead of the troughs of the waves, propagating eastward. READ MORE
