(Peer reviewed; Journal article, 2021-08)In contexts of adversity, there is a need to educate pre-service teachers with specialized content knowledge so they can carry out the work of teaching effectively. This article draws upon a study with three pre-service ... -
Analysis of predicting terminal velocities and impact energies of dropped objects falling through sea column
(Master thesis, 2023)Many offshore operations include risks that might lead to catastrophic consequences. One of the most common offshore risks is the unintentional drop of objects during various marine operations. This work is divided into ... -
Analysis of Residential Household Energy Consumption Using Smart Meter Data
(Masteroppgave/UIS-TN-IDE/2019;, Master thesis, 2019-06-15)The need to change the source of electricity generation is apparent in the effect of climate change on the environment. Asides from the source change to renewable energy, the necessity for residents to understand their ... -
Analysis of ROV thrusters and small marine propellers at specific rotational speeds
(Masteroppgave/UIS-TN-IMBM/2018;, Master thesis, 2018)Thrusters are vital for the functionalities of remotely operated vehicles (ROVs). The development of thruster design is a trade-off between cost, thrust force, physical weight and size. Furthermore, it is known that problems ... -
Analysis of samples of high explosives extracted from explosive remnants of war
(Peer reviewed; Journal article, 2022)Millions of tonnes of dumped ammunition and explosive remnants of war remain in nature both on land and at sea. It is well known that the ordnance could represent a definite explosive risk if disturbed, and that some of ... -
Analysis of slim hole drilling operations
(Masteroppgave/UIS-TN-IPT/2015;, Master thesis, 2015-06-15)Unlike the conventional well technology, slim hole uses a relatively narrower well size. The concept has been introduced long, but the application in petroleum well not very common. Based on its advantage in terms of cost, ... -
Analysis of spar and semi-submersible floating wind concepts with respect to human exposure to motion during maintenance operations
(Peer reviewed; Journal article, 2022)Floating offshore wind turbines (FOWTs) are expected to experience onsite maintenances and inspections during their lifetimes. To carry out offshore maintenance activities, a crew will be transferred to an FOWT and spend ... -
Analysis of structural controls in alluvial fan deposition during late Syn-rotational faulting phase in a half-graben rift system. The Gulf of Corinth, Greece.
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-24)The Kalavrita region is located at the southern margin of the Gulf of Corinth, Greece, and is considered a perfect academic and research laboratory to study the evolution of rift systems and the interaction between tectonics ... -
