Behavioral reasoning perspectives to brand love toward natural products: Moderating role of environmental concern and household size
2021
Abstract Consumers do not easily trust brands’ claims of naturalness, making it essential to understand the drivers of loyalty and the underlying brand love for such products. Responding to this need, the present study developed a conceptual model based on the Behavioral Reasoning Theory (BRT) to examine the antecedents of brand love. The model was tested using data collected through a cross-sectional survey. The findings suggest that health consciousness is positively associated with reasons for consuming natural products and attitude, which, in turn, are also positively associated with each other. At the same time, reasons for consuming natural products and attitude are positively associa…
Mulighetskartlegging for kystbaserte næringer i Agder
2017
I Agder er det et sterkt ønske fra kystkommunene om å tilrettelegge for blå vekst i regionen, men for å realisere dette målet er det behov for faktisk kunnskap om hvilke muligheter havet gir – og utelukker – langs hele Agder-kysten. En slik kartlegging vil være et viktig beslutningsgrunnlag for utvikling av næring knyttet til marin sektor i regionen. Dette danner bakgrunnen for prosjektet «Mulighetskartlegging for kystbaserte næringer i Agder» som er gjennomført i samarbeid mellom NIVA og Havforskningsinstituttet. Målet med prosjektet har vært å (1) Kartlegge naturgitte næringsmuligheter innenfor marin sektor langs Agderkysten, (2) Formidle kunnskap om hvilke muligheter havet gir – og utelu…
Numerical study of a concept for major repair and replacement of offshore wind turbine blades
2020
Repair and replacement of offshore wind turbine blades are necessary for current and future offshore wind turbines. To date, repair activities are often conducted using huge jack-up crane vessels and by applying a reverse installation procedure. Because of the high costs associated with installation and removal of offshore wind turbine components and the low profit margin of the offshore wind industry, alternative methods forinstallation and removal are needed. This paper introduces a novel concept for replacement or installation of offshore windturbine blades. The concept involves a medium-sized jack-up crane vessel and a tower climbing mechanism. This mechanism provides a stable platform …
Adaptive ML-based technique for renewable energy system power forecasting in hybrid PV-Wind farms power conversion systems
2022
Large scale integration of renewable energy system with classical electrical power generation system requires a precise balance to maintain and optimize the supply–demand limitations in power grids operations. For this purpose, accurate forecasting is needed from wind energy conversion systems (WECS) and solar power plants (SPPs). This daunting task has limits with long-short term and precise term forecasting due to the highly random nature of environmental conditions. This paper offers a hybrid variational decomposition model (HVDM) as a revolutionary composite deep learning-based evolutionary technique for accurate power production forecasting in microgrid farms. The objective is to obtai…
Multilevel Inverters with Reduced Component Count for Energy Systems
2021
Paper VI is excluded from the dissertation until it will be published. Multilevel inverters (MLIs) have gained increasing interest for advanced energy-conversion systems with a wide range of voltage levels, due to their attractive features of low harmonic contents, low dv/dt stress, low filtering requirements, low switching frequency, low electromagnetic interference (EMI), and employing low-rated semiconductor devices for producing high voltages. Further, some MLIs have a modularity feature, facilitating voltage and current scalability with high redundancy in switching states, allowing for fault-tolerant operations. The mentioned features are directly related to the number of generated vol…

Autonomous Demand Side Management of Electric Vehicles
2023
There is an error in the table of content, where publication A and B have swiched places. Demand-side management approaches that exploit the temporal flexibility of electric vehicles have attracted much attention in recent years due to the increasing market penetration. These demand-side management measures contribute to alleviating the burden on the power system, especially in distribution grids where bottlenecks are more prevalent. Electric vehicles can be defined as an attractive asset for distribution system operators, which have the potential to provide grid services if properly managed. In this thesis, first, a systematic investigation is conducted for two typically employed demand-si…
Brødbaking for bedre helse
2016
Masteroppgave folkehelsevitenskap - Universitetet i Agder 2016 Introduction: Bread is a part of the Norwegian food culture and a important part of the Norwegian diet. However, the intake of fiber is too low and the health authorities recommend a higher intake of wholemeal bread and cereals. In addition, we throw away as much as 190 000 bread in Norwegian garbage cans every day throughout the year, which is negative in light of the environment. Purpose: This study looks at whether an intervention with the goal of getting participants to bake homemade bread could affect an increased intake of bread, especially intake of whole meal bread, and reduce wastage of bread. The question to answer was…
Extended valence theory perspective on consumers' e-waste recycling intentions in Japan
2021
The gravity of the electronic waste (e-waste) crisis can be attributed to consumers' low participation in ensuring the proper disposal of such materials. Motivating consumers to recycle e-waste requires a deeper understanding of the dimensions that underlie behavioral intentions. Accordingly, the present study uses the novel framework of Valence Theory (VT) to examine how consumers evaluate their decision to recycle e-waste. The authors propose an extended VT model incorporating consumer values (value compatibility, openness to change, and environmental concerns), which is validated using cross-sectional survey data from 774 Japanese consumers. We also examine the role of different moderato…
