Value co-creation and purchase intention in social commerce: The enabling role of word-of-mouth and trust
(Chapter, 2017)Social commerce combines commercial and social activities, and has managed in a very short period of time to attract the interest of researchers and practitioners. In this study we use theories of trust and value co-creation ... -
Value Co-Creation and Trust in Social Commerce: An fsQCA approach
(Chapter, 2017)This study aims to explain how value co-creation, between customers and companies, and key aspects of trust combine to influence customers’ purchase intentions in social commerce. Value co-creation is decomposed into two ... -
Value Comparison of EV and House Batteries at End-user Level under Different Grid Tariffs
(Chapter, 2018)With the introduction of real-time price signals through smart meters, the electric vehicle (EV) battery can become a powerful tool. Its relatively high charging power and capacity makes it attractive for both cost ... -
Value Modeling in the Agricultural Business Sector
(Master thesis, 2007)The growth of global market leads to that more and more organizations face drastic competitions in their industry area. The organizations whose products or services can attract a large amount of customers will take much ... -
The value of airborne wind energy to the electricity system
(Peer reviewed; Journal article, 2021)Airborne wind energy (AWE) is a new power generation technology that harvests wind energy at high altitudes using tethered wings. The potentially higher energy yield, combined with expected lower costs compared to traditional ... -
Value of hydro power flexibility for hydrogen production in constrained transmission grids
(Journal article; Peer reviewed, 2019)The cost of large scale hydrogen production from electrolysis is dominated by the cost of electricity, representing 77–89% of the total costs. The integration of low-cost renewable energy is thus essential to affordable ... -
Value of Information Analysis for Complex Simulator Models: Application to Wind Farm Maintenance
(Peer reviewed; Journal article, 2020)Many domains require the use of sophisticated simulators to adequately model the effect of chosen alternatives on the decision maker’s value. Decision support in such complex systems brings unique challenges around efficiency, ... -
Value of information analysis for subsurface energy resources applications
(Journal article; Peer reviewed, 2019)A computationally efficient method to estimate the value of information in the context of subsurface energy resources applications is proposed. The value of information is a decision analytic metric quantifying the incremental ... -
Value of information analysis in the context of leakage detection in CO2 storage
(Master thesis, 2019)Karbonfangst og -lagring er en lovende strategi for å redusere utslipp av CO2 til atmosfæren og i disse tider forberedes et fullskala prosjekt i Norge. CO2 vil bli injesert i dype geologiske formasjoner, og blant stedene ... -
Value of information analysis of snow measurements for the scheduling of hydropower production
(Journal article; Peer reviewed, 2017)The scheduling of a hydropower plant is challenging because of inflow uncertainty. During spring there is increased uncertainty when the snow melts. By gathering snow measurements, one learns more about the future inflow, ... -
Value of Information in Wireless Sensor Network Applications and the IoT: A Review
