  1. 1. Dataset Drift in Radar Warning Receivers : Out-of-Distribution Detection for Radar Emitter Classification using an RNN-based Deep Ensemble

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Kevin Coleman; [2023]
    Keywords : Radar Emitter Classification; Pulse Descriptor Word; Out of Distribution Detection; Dataset Drift; Uncertainty Estimation; Deep Ensembles; Recurrent Neural Networks; LSTM;

    Abstract : Changes to the signal environment of a radar warning receiver (RWR) over time through dataset drift can negatively affect a machine learning (ML) model, deployed for radar emitter classification (REC). The training data comes from a simulator at Saab AB, in the form of pulsed radar in a time-series. READ MORE

  2. 2. Does in vivo exposure to perfluorooctanesulfonicacid induce an altered colonic barrier function inmice?

    University essay from Örebro universitet/Institutionen för medicinska vetenskaper

    Author : Hanna-Dalia Laar; [2022]
    Keywords : PFOA; PFAS; Ulcerative colitis; colon barrier; gastrointestinal permeability; Ussing Chamber;

    Abstract : Background: Several environmental risk factors have been implicated in the pathogenesis ofinflammatory bowel disease (IBD) and might cause an altered barrier function, a hallmark ofIBD. Recent evidence suggests that patients with late-onset ulcerative colitis (UC) have anincreased serum level of perfluoroalkyl substances (PFAS), one of the major chemical groupscontaminating our diet.

  3. 3. Metagenomic analysis of Crohn’s Disease

    University essay from Uppsala universitet/Molekylär epidemiologi

    Author : Gustav Lennemyr Ahlström; [2022]
    Keywords : Metagenomics; Machine Learning; Microbiome; IBD; Human Health; AI; Crohn s Disease; Shotgun Sequencing Data; Data Analysis; Bioinformatics; MetaPhlAn3; Supervised ML; Mikrobiom; Crohn s Sjukdom; Bioinformatik;

    Abstract : Inflammatory Bowel Disease (IBD) is a chronic and incurable condition that is increasing inprevalence across the globe. This illness consist of two forms: Crohn’s Disease (CD) andUlcerative Colitis (UC). CD is characterised by a patch inflammation pattern across the gut anda multitude of different factors, such as diet. READ MORE

  4. 4. Far-field pattern synthesis of transmitarray antennas using convex optimization techniques

    University essay from KTH/Tillämpad fysik

    Author : Marie Defives; [2022]
    Keywords : Applied physics; Transmitarray antennas; convex optimization; Tillämpad fysik; Transmitarray-antenner; konvex optimering;

    Abstract : Transmitarrays antennas (TAs) can be seen as the planar counterpart of optical lenses. They are composed of thin radiating elements (unit cells) which introduce different local phase shifts on an incident electromagnetic wave, emitted by a primary source, and re-radiate it. READ MORE

  5. 5. INFLAMMATORY BOWEL DISEASE AND IRRITABLE BOWEL SYNDROME IN ADULT LIFE AFTER EXPERIENCING CHILDHOOD ABUSE

    University essay from Örebro universitet/Institutionen för medicinska vetenskaper

    Author : Myella Cederholm; [2021]
    Keywords : ;

    Abstract : Introduction In a national survey from 2016, 5% of Swedish teenagers reported experience of repeated physical abuse and 6% reported repeated psychological abuse. Childhood abuse has been shown to enhance the risk of both psychiatric and somatic diseases, e.g. Irritable bowel syndrome (IBS) and also general inflammation. READ MORE
