Vibration and Fluorescence Spectra of Porphyrin-Cored 2,2-Bis(methylol)-propionic Acid Dendrimers
(Journal article; Peer reviewed, 2009)Bis-MPA dendron-coated free-base tetraphenylporphyrin and zinc-tetraphenyl-porphyrin (TPPH2 and TPPZn) were studied in comparison with simple porphyrins (H2P, ZnP) by theoretical simulation of their infrared, Raman and ... -
Vibration Measurement and Wave Reflection Analysis in an Electrified Railway Catenary Based on Analytical Methods
(Peer reviewed; Journal article, 2021)The wave propagation property of the catenary directly affects the pantograph–catenary interaction performance. Specifically, wave reflection and transmission occurring at waveguide discontinuities, particularly at dropper ... -
Vibration-Based Condition Monitoring of Drivetrains in Large Offshore Wind Turbines in a Digital Twin Perspective
(Doctoral theses at NTNU;2021:109, Doctoral thesis, 2021)According to EU 2050 plan, offshore wind farms based on large floating wind turbines are considered as a main source of power supply in the coming future. Among the turbine systems, drivetrain contributes significantly in ... -
Vibration-based Fault Detection and Condition Monitoring of Mechanical Systems in Wind Turbines
(Master thesis, 2018)An increased energy demand of the future, combined with problems related to climate change and emissions of greenhouse gases, has made solutions for reliable and efficient renewable energy producers attractive. Wind turbines ... -
Vibrational motion in molecules
(Master thesis, 2014)Zero-point vibrational corrections are carried out with analytical geometry and property derivatives at DFT level. This correction is obtained using a variation-perturbation approach, and is carried out around a variationally ... -
Vibrational spectroscopic study of pH dependent solvation at an Ge(100)-water interface during an electrode potential triggered surface termination transition.
(Journal article; Peer reviewed, 2018)The charge-dependent structure of interfacial water at the n-Ge(100)-aqueous perchlorate interface was studied by controlling the electrode potential. Specifically, a joint attenuated total reflection infrared spectroscopy ... -
Vibrations from Magnetic Forces in Hydropower Generators
(Master thesis, 2016)Electrical machines using a fractional slot winding can be subject to low modes of vibration, which can produce noise and stator deformation. The design of a machine has an influence on the amplitude of these deformations, ... -
Vibrations in Composite Timber-Concrete Floor Systems
(Master thesis, 2013)Timber-concrete composite structures were originally developed for bridges and strengthening existing timber floors, but is today used extensively also in new buildings. The objective of this thesis was to look at the ... -
Vibrations' Influence on Human Physiology
(Master thesis, 2015)Vibrations of one type or another are present almost every minute of our daily lives. Much research has been done on high-frequency vibrations influence on human physiology, though less is known about the impact of ... -
Vibroacoustic analysis of the Woodsol timber frame building concept
(Doctoral theses at NTNU;2020:365, Doctoral thesis, 2020)The segment of buildings with four to eight storey is a major share of the building construction market in urban areas. Despite the fact that building with timber has both economical relevance and environmental advantages, ... -
Vicious circles: Violence, vulnerability, and climate change
(Journal article; Peer reviewed, 2021)Climate change threatens core dimensions of human security, including economic prosperity, food availability, and societal stability. In recent years, war-torn regions such as Afghanistan and Yemen have harbored severe ... -
Vico: An entity-component-system based co-simulation framework
(Peer reviewed; Journal article, 2020)This paper introduces a novel co-simulation framework running on the Java Virtual Machine built on a software architecture known as the Entity-Component-System. Popularised by games, this architecture favours composition ... -
