Improved switching strategy for selective harmonic elimination in DC-AC signal generation via pulse-width modulation
(Journal article; Peer reviewed, 2013)We present an advanced design methodology for pulse-width-modulated (PWM) DC-AC signal generation. Using design methods based on the Walsh transform, AC sinusoidal signals can be approximated by suitable PWM signals. For ... -
Improving performance of evolutionary algorithms with application to fuzzy control of truck backer-upper system
(Journal article; Peer reviewed, 2013)We propose a method to improve the performance of evolutionary algorithms (EA). The proposed approach defines operators which can modify the performance of EA, including Levy distribution function as a strategy parameters ... -
Improving the technical properties of recycled aggregates for road construction
(Doctoral Dissertations at the University of Agder; no. 428, Doctoral thesis, 2023)Sustainable construction, operation and maintenance of road infrastructure are currently of high priority in Norway. The development of the highway standards and specifications (e.g., N200) plays an important role, so that ... -

Inconsistencies in the pozzolanic strength activity index (SAI) for silica fume according to EN and ASTM
(Journal article; Peer reviewed, 2014)New supplementary cementitious materials claimed to possess pozzolan properties emerge frequently. This development is driven both by economic and environmental pressures. Properties of new materials are compared with those ... -
Indefinite integrals for some orthogonal polynomials obtained using integrating factors
(Journal article; Peer reviewed, 2020) -
Influence of Aerodynamic Loads on a Dual-Spar Floating Offshore Wind Farm With a Shared Line in Parked Conditions
(Chapter, 2022)The concept of a shared mooring system, in which adjacent wind turbines are coupled by sharing mooring lines, has been proposed to reduce the mooring costs of floating offshore wind farms. This work investigates the influence ... -
The influence of steel fibres on compressive and tensile strength of ultra high performance concrete : A review
(Journal article; Peer reviewed, 2020) -
Influence of unloading modes of spring-mass-damper models on vehicle to pole collision simulation results
(Chapter; Peer reviewed, 2011)Our intention, in this brief note, is to investigate what influence the viscoelastic models' unloading properties have on models' accuracy of representing vehicle crash event. Two types of simple spring-mass-damper systems ... -
Inkludere CO2-regnskap i 3D-modellen for veibyggingsprosjekter
(Master thesis, 2018)For decades, Norwegian roads were constructed and planed by use of printout drawings. Today, as projects increase in scope and complexity, road construction has become a highly collaborative effort, with multiple disciplines ... -
Inneklima og energibruk ved bruk av balansert ventilasjon vs. hybrid ventilasjon i nybygg i massivtre : Skonnertveien Hageby
(Master thesis, 2018)Most apartment buildings today are installed with mechanical balanced ventilation. A measure to reduce energy consumption and still satisfy the demand for heating is to apply hybrid ventilation. That includes using natural ... -
Input-output finite-time stability of discrete-time impulsive switched linear systems with state delays
(Journal article; Peer reviewed, 2013)This paper is concerned with the problem of input-output finite-time stability (IO-FTS) for discrete impulsive switched systems with state delays. Sufficient conditions are presented for the existence of IO-FTS for such ... -
Input-to-state stability of Lur'e hyperbolic distributed complex-valued Parameter control systems: LOI approach
(Journal article; Peer reviewed, 2013)In this work, input-to-state stability of Lur'e hyperbolic distributed complex-valued parameter control systems has been addressed. Using comparison principle, delay-dependent sufficient conditions for the input-to-state ... -
Installation of offshore wind turbines: A technical review
(Peer reviewed; Journal article, 2021) -
Integral Control Action in Precise Positioning Systems with Friction
(Chapter; Peer reviewed, 2016)For high precision positioning systems a fast and accurate settling to the reference state is most significant and, at the same time, challenging from the control point of view. Traditional use of an integral coaction in ... -
Integrated drawingless workflow from design to installation
(Master thesis, 2021)In this master thesis, a methodology for demonstrating both the traditional and the digitalization of reinforcement production’s process for a structural system in an apartment building has been investigated. The purpose ... -
