Preprocessing of Arterial Pressure Waves for Later Use in Modeling of Individual Heartbeats
(Master thesis, 2018)Arterial pressure waves (APW) contain essential information, where the different shape of the waveform can indicate illness or essential information. Furthermore, there can be differences between subject independent of ... -
Present and Future of SLAM in Extreme Environments: The DARPA SubT Challenge
(Peer reviewed; Journal article, 2023)This paper surveys recent progress and discusses future opportunities for Simultaneous Localization And Mapping (SLAM) in extreme underground environments. SLAM in subterranean environments, from tunnels, caves, and man-made ... -
Presenting The Marble Library: Separating the Concerns of Tightly Coupled Abstractions
(Master thesis, 2022)Separasjon av ansvarsområder er et meget effektivt design-prinsipp innen programvareutvikling. Bruken av dette prinsipper fører til fleksibel og ryddig programvare av stor frihetsgrad. Rekursive, hierarkiske strukturer, ... -
Presisjonslanding av telt i kriseområder
(Master thesis, 2017)I denne masteroppgaven er det bygget en prototype og utviklet et kontrollsystem for automatisk styring av en fallskjerm. Prototypen tar sikte på å styre en fallskjerm mot et forhåndsdefinert punkt. Kontrollsystemet er ... -
Pressure and inertia sensing drifters for glacial hydrology flow path measurements
(Peer reviewed; Journal article, 2020)Glacial hydrology plays an important role in the control of glacier dynamics, of sediment transport, and of fjord and proglacial ecosystems. Surface meltwater drains through glaciers via supraglacial, englacial and subglacial ... -
Pressure Control for Offshore Managed Pressure Drilling (MPD): Analysis, Design, and Experimental Validation
(Doctoral thesis at NTNU;2016:96, Doctoral thesis, 2016)Deepwater offshore drilling operations are among the most complex activities. For example in regions such as the Gulf of Mexico, wells are drilled in water depths of up to 3 kilometers, drilling depths can exceed 6 ... -
Pressure wave propagation in Managed Pressure Drilling- model comparison with real life data
(Journal article; Peer reviewed, 2019)Drilling for oil and gas is a complex process, involving pumping of fluid through kilometers of pipes. Even though the drilling fluid has a high speed of sound (˜1000 m/s), the large lengths involved make pressure wave ... -
Preventivt vedlikehold og reduksjon av levetidskostnader ved smart overvåkning av trafikkobjekter ute
(Bachelor thesis, 2022)Rapporten består av tre hoveddeler som ser på overvåkning av forskjellige trafikkobjekter i et veianlegg, henholdsvis elektrisk variable skilt, veibommer og nettanalyse av strømnettet. Det samlede målet for delene er å ... -
Primary color decoding using deep learning on source reconstructed EEG signal responses
(Peer reviewed; Journal article, 2023)The brain’s response to visual stimuli of different colors might be used in a brain-computer interface (BCI) paradigm, for letting a user control their surroundings by looking at specific colors. Allowing the user to control ... -
Principles of digitalisation and IT-OT integration
(SINTEF AS (ISBN starter med 978-82-14-), Research report, 2023)The purpose of this report is to provide the industry with a greater understanding of ongoing digitalisation, status and challenges, and how this development should be managed going forward. This report is one of six SINTEF ... -
Prinsipper for bruk av krypteringsnøkler for ERTMS i Norge
(Master thesis, 2015)I forbindelse med innføring av det nye signalsystemet ERTMS (European Rail Traffic Management System) i Norge, må det etableres en organisasjon for kryptering og krypteringsnøkkelhåndtering i Jernbaneverket. I ERTMS ... -
A priori analysis on deep learning of subgrid-scale parameterizations for Kraichnan turbulence
(Peer reviewed; Journal article, 2020)In the present study, we investigate different data-driven parameterizations for large eddy simulation of two-dimensional turbulence in the a priori settings. These models utilize resolved flow field variables on the coarser ... -
Priority Based Message Stack
(Master thesis, 2008)To enable deterministic scheduling in a distributed embedded system an existing open source embedded TCP/IP stack has been modified to support strict priority queuing. The embedded target system has a fully switched ... -
Proactive Actuator Fault-Tolerance in Economic MPC for Nonlinear Process Plants
(Journal article; Peer reviewed, 2016)This paper presents a scheme for proactive accommodation of incipient actuator faults in nonlinear process plants operated with economic model predictive control (EMPC). The control scheme implements a switching from nominal ... -
Proactive Collision Avoidance for ASVs using A Dynamic Reciprocal Velocity Obstacles Method
(Journal article; Peer reviewed, 2018)We propose a collision avoidance method that incorporates the interactive behavior of agents and is proactive in dealing with the uncertainty of the future behavior of obstacles. The proposed method considers interactions ... -
Proactive maritime collision avoidance based on historical AIS data
(Master thesis, 2019)I de siste årene har det blitt utviklet flere maritime anti-kollisjonssystemer (COLAV-system) for autonome overflatefartøy (ASV). Mange metoder inkluderer løsninger for å følge Konvensjonen om internasjonale regler til ... -
