Investigation of the Hydroelectric Development Potential of Nonpowered Dams: A Case Study of the Buyuk Menderes River Basin
(Peer reviewed; Journal article, 2023)The adaptation of nonpowered dams (NPDs) to dams with hydroelectric generation units requires only minor interventions compared with the construction of a completely new dam and power plant. Thus, it is both more economical ... -
The investigation of the influence of thermal plume and breathing on sleeping microenvironment
(Peer reviewed; Journal article, 2021)Most of humans’ lifetime was spent indoor, especially in bedroom. Thus, understanding the characteristics of the sleep microenvironment is a prerequisite for better control and improvement of our sleeping environment. This ... -
Investigation of the microstructure evolution and deformation mechanisms of a Mg-Zn-Zr-RE twin-roll-cast magnesium sheet by in-situ experimental techniques
(Journal article; Peer reviewed, 2018)Twin roll casting (TRC), with a relatively fast solidification rate, is an excellent production method with promising potential for producing wrought semi or final Mg alloy products that can often suffer from poor formability. ... -
Investigation of the Model Structure for Low-Order Grey-Box Modelling of Residential Buildings
(Chapter, 2019)Model Predictive Control (MPC) is a key technology to activate the building energy flexibility. A reliable control-based model should be developed for each specific building. The structure of grey-box models is usually ... -
Investigation of the Numerical Methodology of a Model Wind Turbine Simulation
(Journal article; Peer reviewed, 2018)The present work aims to investigate different methodologies for the numerical simulation of an upwind three-bladed wind turbine; which is supposed to be a base model to simulate icing in cold climate windmills. That is a ... -
Investigation of the products of the dolomite reaction in Portland cement pastes
(Chapter; Peer reviewed, 2017)The formation of potentially deleterious reaction products from the reaction of dolomite fines in Portland cement pastes was investigated. It was shown that the reaction of dolomite fines did not follow the commonly accepted ... -
Investigation of the relationship between water quality variations and cavitation occurence in power plants
(Doctoral thesis at NTNU;2016:26, Doctoral thesis, 2016)Lab experiments on clean water samples have revealed that water may withstand large tension; a state which could be explained as negative pressure, without occurrence of cavitation. At the same time, one struggles to ... -
Investigation of the Rheological Properties of Asphalt Binder Containing Graphene Nanoplatelets
(Master thesis, 2016)Årlig produksjon av asfalt i Norge er ca. 6 millioner tonn per år med det total verdi ca. 5 milliarder kroner. En stor del av dette beløpet er for reasfaltering av det eksisterende vegnettet. Ofte er grunnen for tidlig ... -
Investigation of the StationMar concept to validate the principle of the structure and find corresponding challenges to develop a functional system
