  2. 1. Mobility and Multi-channel Communications in Low-power Wireless Networks

    Author : António Gonga; Mikael Johansson; Riku Jäntti; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobility; Multi-channel communications; Neighbor Discovery; MAC Protocols; Low-power Wireless Networks; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The prospect of replacing existing fixed networks with cheap, flexible and evenmobile low-power wireless network has been a strong research driver in recent years.However, many challenges still exist: reliability is hampered by unstable and burstycommunication links; the wireless medium is getting congested by an increasingnumber of wireless devices; and life-times are limited due to difficulties in developingefficient duty-cycling mechanisms.

  4. 2. On Symmetries and Metrics in Geometric Inference

    Author : Giovanni Luca Marchetti; Danica Kragic; Anastasiia Varava; Emanuele Rodolà; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Machine Learning; Computational Geometry; Voronoi; Delaunay; Symmetry; Equivariance; Datalogi; Computer Science;

    Abstract : Spaces of data naturally carry intrinsic geometry. Statistics and machine learning can leverage on this rich structure in order to achieve efficiency and semantic generalization. Extracting geometry from data is therefore a fundamental challenge which by itself defines a statistical, computational and unsupervised learning problem. READ MORE

  5. 3. Data analytics for weak spot detection in power distribution grids

    Author : Hassan Mashad Nemati; Sławomir Nowaczyk; Anita Pinheiro Sant'Anna; Math Bollen; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This research aims to develop data-driven methods that extract information from the available data in distribution grids for detecting weak spots, including the components with degraded reliability and areas with power quality problems. The results enable power distribution companies to change from reactive maintenance to predictive maintenance by deriving benefits from available data. READ MORE

  6. 4. Innate lymphoid cell differentiation and functions in intestinal homeostasis and disease

    Author : Efthymia Kokkinou; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The gastrointestinal (GI) tract, which includes the small and the large intestine, is considered the largest immunological organ that plays a pivotal role in food digestion, nutrient absorption and fuel generation. Inflammatory Bowel Disease (IBD), which is broadly divided into Crohn’s disease (CD) and Ulcerative Colitis (UC), are multifactorial chronic intestinal inflammatory conditions that affect both pediatric and adult patients.
