Wienerization Based Control of Nonlinear Systems
(Chapter, 2022)We present a novel model approximation scheme, named “wienerization”, of nonlinear time invariant systems that uses the systems' nonlinear equilibria maps as the static nonlinearities of Wiener models. We show conditions ... -
Wienerization of systems in nonlinear control canonical normal form
(Chapter, 2022)We extend the concept of model approximation via wienerization to systems in nonlinear control canonical normal form. We elaborate on the conditions for, and implications of, analytically separating nonlinear input affine ... -
WiMAX in Coastal Traffic and Performance Prediction in a Geographically Challenging Environment
(Master thesis, 2009)This thesis takes upon itself to describe the medium of the radio channel for a WiMAX installation in a difficult environment. Furthermore it investigates the possibility of modifying the WiMAX standard in order to increase ... -
Wind Estimation with Multirotor UAVs
(Peer reviewed; Journal article, 2022)Unmanned Aerial Vehicles (UAVs) have benefited from a tremendous increase in popularity over the past decade, which has inspired their application toward many novel and unique use cases. One of them is the use of UAVs in ... -
Wind farm control - Part I: A review on control system conceptsand structures
(Journal article; Peer reviewed, 2021)Wind farm control design is a recently new area of research that has rapidly become a key enabler for the development of large wind farm projects and their safe and efficient connection to the power grid. A comprehensive ... -
Wing-Augmented Articulated Intervention Autonomous Underwater Vehicle
(Master thesis, 2020)Økende temperaturer og forurensing av havet har ført til et økt ønske om å kartlegge havets klima og bærekraftighet. To klasser av undervannsroboter som særlig har utmerket seg for dette formålet i nyere tid er den artikulerte ... -
Wire Arc Additive Manufacturing by Robot Manipulator: Towards Creating Complex Geometries
(Journal article; Peer reviewed, 2019)Additive manufacturing (AM) is the umbrella term that covers a variety of techniques that build up structures layer-by-layer as opposed to machining and other subtracting methods. It keeps evolving as an important technology ... -
Wire-arc additive manufacturing of structures with overhang: Experimental results depositing material onto fixed substrate
(Peer reviewed; Journal article, 2022)As additive manufacturing (AM) technology grows both more advanced and more available, the challenges and limitations are also made more evident. Most existing solutions for AM build structures layer by layer using strictly ... -
Wireless Positioning and Collision Avoidance System
(Master thesis, 2012)Early in the 1980's Jens G. Balchen wanted to create an autonomous bike, capable of driving without any help from supporting wheels or human interaction. The intriguing idea included a variety of complicated concepts and ... -
Wireless Surface Interface for Subsea Instrumentation
(Master thesis, 2016)The buoy controller platform enables data acquisition from the connectable acoustic receiver, in addition to the other implemented log devices and connectable instruments. This allows the buoy platform to provide functionality ... -
wirSENSE: A General WirelessHART Sensor Platform
(Master thesis, 2008)The development of wireless sensor networks (WSNs) has grown rapidly during the last few years. Much because of the introduction of the IEEE 802.15.4 standard in 2003, which provides the basis for several WSNs. The ZigBee ... -
Wood burning habits and its effect on the electrical energy demand of a retrofitted Norwegian detached house
(Journal article; Peer reviewed, 2019)Using firewood as a space heating source is a popular solution in Norwegian housing and can significantly reduce the electrical energy demand of houses. This study analysed habits and reasons for using a wood stove from ... -
Worst-case Performance Analysis of Scenario-aware Real-time Streaming Applications
(Doctoral thesis at NTNU;2016:245, Doctoral thesis, 2016)An embedded system is a combination of hardware and software designed to perform a dedicated function. Embedded systems typically come with stringent performance constraints such as throughput, latency, memory demands and ... -
Worst-case performance analysis of SDF-based parameterized dataflow
(Journal article; Peer reviewed, 2016)Dynamic dataflow models of computation (MoCs) have been introduced to provide designers with sufficient expressive power to capture increasing levels of dynamism in present-day streaming applications. Among dynamic dataflow ... -
Yaw Error Estimation on the NREL 5-MW Offshore Baseline Wind Turbine
(Master thesis, 2023)Utviklingen av beregningseffektive og nøyaktige inflow-dynamikker, sammen med økende beregningskapasitet, muliggjør undersøkelse av den relativt uutforskede tilnærmingen til tilstandsestimering for å finne et feilestimat ... -
Zero-Emission Autonomous Ferries for Urban Water Transport: Cheaper, Cleaner Alternative to Bridges and Manned Vessels
(Journal article, 2019)Because water is an integral part of day-to-day life for humans, civilizations have generally flourished either in coastal areas or near river basins. Today, about 40% of the world?s population lives near a coast and many ...
