Performance Modeling of a Finite Volume Method for the Shallow Water Equations
(Master thesis, 2022)Oppgaven omhandler en proxy-applikasjon for å beregne grunnvannsligningene gjennom den endelige volummetoden. Vannoverflaten er diskretisert gjennom en triangulering, der kystlinjen til Mehamn brukes til alle tester. ... -
Performance Modeling of a Load-Balanced FDM Wave Equation Solver on Heterogeneous Clusters
(Master thesis, 2023)I denne avhandlingen utvikles en skalerbar implementasjon av endelig differansemetode for å løse den todimensjonale bølgelikningen. Vi utvikler algoritmer som benytter lastbalansering i flere lag for å sikre at ... -
Performance Modeling of Adaptive Mesh Refinement for the Shallow Water Equations
(Master thesis, 2020)I denne avhandlinga studerer me ytings- og skalerings-karakteristikkar ved adaptivt raffinerte endelege differansar-løysingar av gruntvasslikningane. Gruntvasslikningane er eit sett med likningar som blir nytta til å ... -
Performance modeling of CFD application scalability using co-design methods
(Master thesis, 2018)In this thesis, we investigate the performance and scalability of two CFD proxy applications, based on the Lattice Boltzmann Method (LBM) and Smoothed Particle Hydrodynamics (SPH). Two variants of LBM, workshare and task, ... -
Performance Modeling of Finite Difference Shallow Water Equation Solvers with Variable Domain Geometry
(Master thesis, 2021)I denne oppgaven undersøker vi metoder som kan brukes til å redusere ubalansert beregningslast, som kan oppstå når man dekomponerer et todimensjonalt domene av endelige differanser med ujevn beregningskostnad. I dette ... -
Performance Modeling of Heterogeneous Systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:344, Doctoral thesis, 2012)As the complexity of parallel computers grows, constraints posed by the construction of larger systems require both greater, and increasingly non-linear, parameter sets to model their behavior realistically. These heterogeneous ... -
Performance modeling of subdomain discretization techniques for SPH proxy applications
(Master thesis, 2021)In this study we investigate the performance of two cell-grid discretization schemes for a smoothed-particle hydrodynamics (SPH) proxy application that is applied to the two-dimensional dam-break problem. The Cell+Table ... -
Performance of machine learning models in estimation of ground reaction forces during balance exergaming
(Peer reviewed; Journal article, 2022)Background Balance training exercise games (exergames) are a promising tool for reducing fall risk in elderly. Exergames can be used for in-home guided exercise, which greatly increases availability and facilitates ... -
Performance Study of Random Walk Simulations
(Master thesis, 2009)Our research shows that generation of random numbers in the benchmark Random Walk application is a significant fraction of the overall computational time in Random Walk simulations (40%). Furthermore, we show that choice ... -
Performing reproductions to understand the state of reproducibility in current AI research
(Master thesis, 2018)In the last few years, the issue of reproducibility has gained increased attention in many scientific fields, including Artificial Intelligence (AI). Reproducibility of published results is a key concept of the scientific ... -
Perovskite Color Detectors: Approaching the Efficiency Limit
(Peer reviewed; Journal article, 2020)Color image sensing by a smartphone or digital camera employs sensor elements with an array of color filters for capturing basic blue, green, and red color information. However, the normalized optical efficiency of such ... -
Persistence Initialization: a novel adaptation of the Transformer architecture for time series forecasting
(Peer reviewed; Journal article, 2023)Time series forecasting is an important problem, with many real world applications. Transformer models have been successfully applied to natural language processing tasks, but have received relatively little attention for ... -
Personal data processing and social mission of actors within the public administration
(Master thesis, 2023)Den kontinuerlige teknologiutviklingen har gjort det mulig å analysere data i større skala enn noen gang før, noe som gir nye muligheter når det gjelder digitalisering av norsk offentlig forvaltning. Aktørene i den offentlige ... -
Personal Health Information on Display: Balancing Needs, Usability and Legislative Requirements
(Journal article; Peer reviewed, 2011)Large wall-mounted screens placed at locations where health personnel pass by will assist in self-coordination and improve utilisation of both resources and staff at hospitals. The sensitivity level of the information ... -
Personal health record as a backbone for primary healthcare in developing countries
(Master thesis, 2007)Increasingly, the ability to improve the efficiency, safety and quality of care is being recognized across the primary health sector. Increased focus on "seamless delivery of care", particularly for those with complex care ... -
