Perception-Driven Obstacle-Aided Locomotion for snake robots, linking virtual to real prototypes
(Master thesis, 2017)Snake robots have the potential to be used for many tasks where maneuvering through narrow and uneven terrain is necessary. Examples of such tasks include search-and-rescue missions, firefighting and pipe inspection. Real ... -
Perception-Driven Obstacle-Aided Locomotion for Snake Robots: The State of the Art, Challenges and Possibilities
(Journal article; Peer reviewed, 2017)In nature, snakes can gracefully traverse a wide range of different and complex environments. Snake robots that can mimic this behaviour could be fitted with sensors and transport tools to hazardous or confined areas that ... -
Performance Analysis of Nonlinearly Controlled Motion Systems
(Master thesis, 2009)In this thesis, we investige the applicability of the certain numerical methods for the solution of certain systems of partial differential equations. Numerical methods for this purpose are studied, in particular the finite ... -
Performance analysis of safety barriers against cascading failures in a battery pack
(Peer reviewed; Journal article, 2022)Lithium-ion batteries have been widely employed as the principal power source in electric vehicles and other storage systems. However, some critical issues in a battery pack still exist, such as thermal failures on initial ... -
Performance analysis of safety instrumented systems against cascading failure during prolonged demand
(Peer reviewed; Journal article, 2021)Cascading failures may occur in many technical systems where the failure of one component triggers successive events. Safety barriers like safety instrumented systems are installed in many industries to prevent failures ... -
Performance assessment of K-out-of-N safety instrumented systems subject to cascading failures
(Peer reviewed; Journal article, 2021)Safety instrumented systems often employ redundancy to enhance the ability to detect and respond to hazardous events. The use of redundancy increases the fault tolerance to single failure but remains vulnerable in case of ... -
Performance Bounds for Tracking Multiple Objects using a Single UAV
(Chapter, 2017)In this paper we calculate probabilistic estimates for the size of an area a single unmanned aerial vehicle (UAV) can expect to monitor when tracking multiple objects. The objects are assumed to move according to a linear ... -
Performance Comparison of Backstepping-Based Adaptive Controllers for Marine Surface Vessels
(Chapter, 2016)This paper deals with the design and evaluation of three controllers based on backstepping and different adaptive control schemes, which are applied to the motion control of a nonlinear 3 degrees-of-freedom model of a ... -
Performance Comparison of Controllers with Fault-Dependent Control Allocation for UAVs
(Journal article; Peer reviewed, 2017)This paper combines fault-dependent control allocation with three different control schemes to obtain fault tolerance in the longitudinal control of unmanned aerial vehicles. The paper shows that fault-dependent control ... -
Performance evaluation of different Kalman filters for state estimation of lithium-ion batteries
(Master thesis, 2022)Litium-ion-batterier representerer en enorm industri og har vist seg å være en sentral teknologi for å redusere klimagasser. Ettersom elektrifiseringen av transportsektoren fortsetter å øke, vil de potensielle gevinstene ... -
Performing Dynamic Manipulation of a Rolling Object on the Butterfly Robot with Perturbation in System Parameters
(Master thesis, 2021)En av de vanskeligste aspektene ved ˚a reprodusere menneskelig atferd i robotikk er ˚a utføre ikke-prehensile (ikke-gripende) objektmanipulering. Dersom roboter skal kunne integreres i en menneskeskapt verden, m˚a de være ... -
A Persistent Sea-Going Platform for Robotic Fish Telemetry Using a Wave-Propelled USV: Technical Solution and Proof-of-Concept
(Peer reviewed; Journal article, 2022)Over the last few decades, acoustic fish telemetry has developed into a viable approach for remote monitoring of fish behaviour in the marine environment. Simultaneously, unmanned surface and underwater vehicles have found ... -
Petrel Software Usability Study: Using the Microsoft Kinect v2 for Workflow Execution
(Master thesis, 2015)The computer mouse has been one of the most commonly used interaction devices for a long time. This thesis set out to explore new interaction possibilities in regards to effectiveness, efficiency and satisfaction. The ... -
Petri nets for modelling and calculations
(Master thesis, 2014)A Petri net is a mathematical, graphical, executable technique for the specification, modeling and analysis of concurrent, discrete-event dynamic systems. Petri net is a directed bipartite graph, in which the nodes represent ... -
Petroleum production optimization - A static or dynamic problem?
(Journal article; Peer reviewed, 2018)This paper considers the upstream oil and gas domain, or more precisely the daily production optimization problem in which production engineers aim to utilize the production systems as efficiently as possible by for instance ... -
