  1. 1. Modelling and Inference for Spatio-Temporal Marked Point Processes

    Författare :Ottmar Cronie; Göteborgs universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Asymptotic normality; Consistency; Cox-Ingersoll-Ross process; Diffusion process; Edge correction; Goodness-of-fit; Richards growth function; Growth-interaction process; Immigration-death process; Least squares estimation; Markov process; Maximum likelihood estimation; Open-growth; Spatio-temporal marked point process; Stationarity; Stochastic differential equation; Transition density; Asymptotic normality;

    Sammanfattning : This thesis deals with inference problems related to the growth-interaction process (GI-process). The GI-process is a continuous time spatio-temporal point process with dynamic interacting marks (closed disks), in which the immigration-death process (ID-process) controls the arrivals of new marked points as well as their potential life-times.

  3. 2. A Non-Gaussian Limit Process with Long-Range Dependence

    Författare :Raimundas Gaigalas; Ingemar Kaj; Esko Valkeila; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; long-range dependence; traffic modelling; arrival process; self-similarity; heavy tails; fractional Brownian motion; stable processes; renewal processes; independently scattered random measure; weak convergence; 60F17; 60G18; 90B18; 60K05 ; Matematisk statistik; Mathematical statistics; Matematisk statistik;

    Sammanfattning : This thesis, consisting of three papers and a summary, studies topics in the theory of stochastic processes related to long-range dependence. Much recent interest in such probabilistic models has its origin in measurements of Internet traffic data, where typical characteristics of long memory have been observed. LÄS MER

  4. 3. Just-in-Time Arrival in Port Calls : Potential and Implementation

    Författare :Abdalla Mubder; Anna Fredriksson; Joakim Kalantari; Niklas Arvidsson; Linda Styhre; Abd Alla Ali Mubder Mubder; Statens väg- och transportforskningsinstitut; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maritime transportation; Port call process; Just-in-Time arrival; Coordination and information sharing; Port community system;

    Sammanfattning : There is an urgent need to reduce emissions from maritime transportation to meet environmental targets set by international organizations and governments. To reduce emissions from maritime transportation, technical, market-based, and operational measures can be used. LÄS MER

  5. 4. Den svenska aidsepidemin : Ankomst, bemötande, innebörd

    Författare :David Thorsén; Sven Widmalm; Annika Berg; Per Axelsson; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; history of medicine; HIV; AIDS; epidemic; AIDS policy; public health; health promotion; drug policy; path dependency; governmentality; Sweden; aidsdelegationen; folkhälsoinstitutet; Nils Bejerot; AIDS posters; History of Sciences and Ideas; Idé- och lärdomshistoria;

    Sammanfattning : This dissertation investigates the public response to HIV/AIDS in Sweden in the 1980s and early 1990s. The analysis focuses on the National Commission on AIDS (NCA,“Aidsdelegationen”). LÄS MER

  7. 5. Mapping and Merging Using Sound and Vision : Automatic Calibration and Map Fusion with Statistical Deformations

    Författare :Gabrielle Flood; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Time of arrival; TOA; Time-difference of arrival; TDOA; Subsample methods; Uncertainty measure; Constant offset; RANSAC; Map merging; Map fusion; Change detection; Collaborative SLAM; Structure from motion; SfM; SLAM; Mapping; Localisation; Registration; Sparse maps; Point clouds;

    Sammanfattning : Over the last couple of years both cameras, audio and radio sensors have become cheaper and more common in our everyday lives. Such sensors can be used to create maps of where the sensors are positioned and the appearance of the surroundings. LÄS MER
