  1. 1. Reconstructing point patterns from spatially aggregated data

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Jens Michelsen; [2024-03-13]
    Keywords : lorem; ipsum; dolor; sit; amet; consectetur; adipisicing; elit; sed; do.;

    Abstract : In this thesis we explore the ability to reconstruct samples (point configurations) from a point process, based only on the information contained in spatially aggregated data, namely the number of points in the partitions of a larger region. The ability to reconstruct a point configuration, in such a way that it retains most of it’s statistical properties, could be useful in cases where one is faced with a mixed dataset; some regions containing the full point configuration data, while other regions only contain aggregated data, i.

  3. 2. Adherence in patients with heart failure. Relationships to symptom burden and hospitalization frequency : A cross-sectional survey study

    University essay from Malmö universitet/Institutionen för vårdvetenskap (VV)

    Author : Helen Moe; [2024]
    Keywords : Adherence; Cross sectional study; Heart failure; Hospitalization-frequency; Non-adherence; Symptom burden;

    Abstract : Aim: The aim of the study was to investigate the degree of adherence and non-adherence to treatment regimen in the population with heart failure, as well as to explore relationships to symptom burden and hospitalization-frequency. Introduction: Heart failure – a chronic disease with a somber prognosis and high mortality, incidence and prevalence increasing world-wide. READ MORE

  4. 3. Data analytics and machine learning for railway track degradation: Using Bothnia Line track measurements for maintenance forecasting

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : Elie Roudiere; [2024]
    Keywords : Railway; Track geometry; Machine learning; Statistics; Predictive maintenance; Botniabanan; Järnväg; spårgeometri; maskininlärning; statistik; förebyggande underhåll; Botniabanan;

    Abstract : In this paper, a statistical method is developed to improve predictive maintenance on railway track. The problem tackled is being able to predict when the next maintenance event should take place to guarantee a certain track quality class. READ MORE

  5. 4. Syntax-based Concept Alignment for Machine Translation

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Arianna Masciolini; [2023-03-30]
    Keywords : computational linguistic; machine translation; concept alignment; syntax; dependency parsing; Universal Dependencies; Grammatical Framework;

    Abstract : This thesis presents a syntax-based approach to Concept Alignment (CA), the task of finding semantical correspondences between parts of multilingual parallel texts, with a focus on Machine Translation (MT). Two variants of CA are taken into account: Concept Extraction (CE), whose aim is to identify new concepts by means of mere linguistic comparison, and Concept Propagation (CP), which consists in looking for the translation equivalents of a set of known concepts in a new language.

  6. 5. Robust Aircraft Positioning using Signals of Opportunity with Direction of Arrival

    University essay from Linköpings universitet/Reglerteknik

    Author : Erik Axelsson; Sebastian Fagerstedt; [2023]
    Keywords : Simultaneous localisation and mapping; direction of arrival; signals of opportunity; extended Kalman filter; positioning;

    Abstract : This thesis considers the problem of using signals of opportunity (SOO) with known direction of arrival (DOA) for aircraft positioning. SOO is a collective name for a wide range of signals not intended for navigation but which can be intercepted by the radar warning system on an aircraft. READ MORE
