High-Level Visual Masking of Image Compression Artefacts
(Chapter, 2020)We present the results of a subjective experiment where we measured detection thresholds for 2°wide noise targets placed in 23 different natural scenes. Unlike previous studies on visual masking, we focus particularly on ... -
High-Order Schemes for the Shallow Water Equations on GPUs
(Master thesis, 2013)In this thesis, well-balanced, central-upwind high-resolution methods of high order are developed for the two-dimensional shallow water equations, on the graphics processing unit (GPU). The methods are based on a fifth-order ... -
High-performance Asynchronous Byzantine Fault Tolerance Consensus Protocol
(Master thesis, 2021)For å imøtekomme nye og banebrytende blockchain-baserte systemer innen Supply Chain Management (SCM) og Internet of Things (IoT), så er det et behov for konsensus mekanismer som kan sikre høy transaksjonsgjennomstrømning ... -
High-Performance Asynchronous Byzantine Fault Tolerance Consensus Protocol
(Chapter, 2021)In response to new and innovating blockchain-based systems with Internet of Things (IoT), there is a need for consensus mechanisms that can provide high transaction throughput and security, despite varying network quality. ... -
High-Performance Computation of Bézier Surfaces on Parallel and Heterogeneous Platforms
(Journal article; Peer reviewed, 2017)Bézier surfaces are mathematical tools employed in a wide variety of applications. Some works in the literature propose parallelization strategies to improve performance for the computation of Bézier surfaces. These ... -
High-Performance X-ray Scattering Simulations
(Master thesis, 2018)This thesis is part of a larger project in the field of computational microscopy. Its main contribution is to facilitate the implementation of high performance tools to assist in the understanding and simulation of microscopic ... -
High-speed Echoes in the Polar Winter Mesosphere: Infrasound as a Probable Cause
(Peer reviewed; Journal article, 2023)We considered three events on 4 November 2015, 22 December 2016, and 12 November 2018, when the signals travelling in the polar winter mesosphere with high horizontal velocities above 300 m/s were measured by the atmospheric ... -
Highly available database clusters: Repair with large segments
(Master thesis, 2005)The goal for this master thesis is finding trends and behaviors in a highly available database cluster using InfiniBand and RDMA. This will be used to optimize configuration of the segment size in such systems. To find ... -
Highly Efficient Pattern Mining Based on Transaction Decomposition
(Chapter; Peer reviewed, 2019)This paper introduces a highly efficient pattern mining technique called Clustering-Based Pattern Mining (CBPM). This technique discovers relevant patterns by studying the correlation between transactions in transaction ... -
HikePal: A mobile exergame to motivate people with intellectual disabilities to do outdoor physical activities
(Peer reviewed; Journal article, 2022)People with intellectual disabilities often have a sedentary lifestyle that can lead to long-term issues like cardiovascular diseases, diabetes, obesity and depression. Although literature shows that the main reason for ... -
Hilbert-Geohash - Hashing Geographical Point Data Using the Hilbert Space-Filling Curve
(Master thesis, 2016)As geographic information systems become more and more widely used, an increasing amount of positional data is generated and shared between users. Sharing spatial data introduces challenges, with URLs containing lengthy ... -
Historien om, utviklingen av og fremtiden til programmeringsspråk
(Bachelor thesis, 2024)De fleste programmerere har møtt på en eller flere av følgende «skrekkhistorier»: Man må lete i en gigantisk trestruktur, for å finne ut hvor koden er, og hva den gjør. Eller man må bruke all sin tid på å jobbe med selve ... -
