Prototype of HIL Test Platform for Autonomous USV - Simulation of Vessel Dynamics
(Master thesis, 2017)This thesis considers the modeling of vessel dynamics and implementation of a prototype Hardware-In-The-Loop (HIL) simulator for two autonomous unmanned surface vehicles (USVs) of different dimensions in 6 degrees of ... -
Prototyping an OPC UA Server for Use in an Information Management System
(Master thesis, 2011)When oil fields produce less in the late part of their life cycle, oil companies must run their operations more efficient. One of the methods for running their operations efficiently is called Integrated Operations (IO). ... -
ProXC++ - A CSP-inspired Concurrency Library for Modern C++ with Dynamic Multithreading for Multi-Core Architectures
(Master thesis, 2017)Ever since mass-market processors transitioned from single-core to multi-core architectures, software could no longer rely on an increase in sequential performance for an increase in software performance. Now, developing ... -
Pruning of RBF Networks in Robot Manipulator Learning Control
(Master thesis, 2012)Radial Basis Function Neural Networks are well suited for learning the systemdynamics of a robot manipulator and implementation of these networks in thecontrol scheme for a manipulator is a good way to deal with the system ... -
PSB-MPC Collision Avoidance with Anti-Grounding
(Master thesis, 2021)Denne avhandlingen ser på autonome overflatefartøy (AO) som fremtiden til industriell maritim shipping. For å oppnå en fullstendig autonom AO så har videre arbeid på et robust og komplett kollisjonsunngåelsessystem blitt ... -
Pseudo-Hamiltonian neural networks with state-dependent external forces
(Peer reviewed; Journal article, 2023)Hybrid machine learning based on Hamiltonian formulations has recently been successfully demonstrated for simple mechanical systems, both energy conserving and not energy conserving. We introduce a pseudo-Hamiltonian ... -
PSO and Kalman Filter-Based Node Motion Prediction for Data Collection from Ocean Wireless Sensors Network with UAV
(Peer reviewed; Journal article, 2021)In this paper, we consider a wireless sensor network of nodes at the sea surface drifting due to wind and sea currents. In our scenario an Unmanned Aerial Vehicle (UAV) will be used to gather data from the sensor nodes. ... -
Psychological stress detection with optimally selected EEG channel using Machine Learning techniques
(Peer reviewed; Journal article, 2023)Psychological stress buildup can lead to mental disorders, early mortality, stroke and sudden cardiac arrest and therefore, timely stress detection is important for reducing human suffering. This study aims to present a ... -
Pulsatile insulin infusion in closed-loop glucose control in diabetes mellitus type 1
(Master thesis, 2015)Diabetes is a chronic decease which affect the body's ability to regulate the blood glucose level(BGL). Not being able to maintain a steady BGL can lead to many severe complications. There is done much effort in order to ... -
PWM investigation of a Field-oriented controlled Five-Phase PMSM under two-phase open faults
(Peer reviewed; Journal article, 2020)The decoupled model of Five-Phase Permanent Magnet Synchronous Motors (5Ph PMSMs) under a two-phase open circuit has been developed recently, yet the corresponding PWM has not been fully exploited. The Pulse Width Modulation ... -
