Evaluation of Welded Clad Pipe - Microstructures and Properties
(Master thesis, 2015)Clad pipes are used in the oil and gas industry for transportation of corrosive substances. Maintenance, repairs and tie-in connections to existing subsea structures is done by hyperbaric welding. There is per today no ... -
Evaluation of Welded Clad Pipe - Properties and Simulations
(Master thesis, 2017)Pipelines are an essential part of the oil and gas offshore industry, for transporting unprocessed oil and gas from the seabed to the oil platform and to the mainland. The unprocessed oil and gas leaves a corrosive ... -
Evaluation of Well Control Procedure for Managed Pressure Drilling
(Master thesis, 2011)To be able to drill deeper, in depleted reservoirs, and in new complicated formations, new techniques must be developed and evaluated. Conventional systems for drilling are still the most common method for drilling wells, ... -
Evaluation of Wellhead Fatigue for Drilling Risers - A Study on the Effect of Tension
(Master thesis, 2015)In the oil and gas industry today, there is a renewed focus on structural integrity of the well- head. There exists no codes or standards on how to calculate wellhead fatigue today. However, a Joint Industry Project (JIP) ... -
Evaluation of Work Flow in Drilling and Completion
(Master thesis, 2014)Integrity verification is essential to safe planning of wells. Although the complexity of wells has increased over the last decades, the process of integrity verification has not seen any significant changes. In order to ... -
Evaluation of workplace quality - A method for improvement and further development of workplace design for the future
(Master thesis, 2012)Background for Master’s Thesis Research Most of the workspace inhabited by people today were developed in and according to work needs in a time when the pace and character of changes in work were much less pronounced ... -
Evaluation of “Autotune” calibration against manual calibration of building energy models
(Journal article; Peer reviewed, 2016)This paper demonstrates the application of Autotune, a methodology aimed at automatically producing calibrated building energy models using measured data, in two case studies. In the first case, a building model is de-tuned ... -
Evaluation og hPSCs-derived Hepatocyte-like cells in native and modified alginates
(Master thesis, 2020)Dette arbeidet studerer det terapeutiske potensialet til hepatocytt-liknende celler (HLC-er) generert fra humane pluripotente stamceller ved en ny metode kalt "forward programming" (FoP). Knappheten av tilgjengelige levere ... -
Evaluation on Overheating Risk of a Typical Norwegian Residential Building under Future Extreme Weather Conditions
(Journal article; Peer reviewed, 2020)As the temperature in the summer period in Norway has been always moderate, little study on the indoor comfort of typical Norwegian residential buildings in summer seasons can be found. Heat waves have attacked Norway in ... -
Evaluation on stability condition along the headrace tunnel of Kulekhani-III Hydroelectric Project
(Master thesis, 2020)With over 90% of the country’s total electricity generation capacity generated by hydropower plants, Nepal is heavily dependent on hydro resources to meet its energy demands. Best use of water using the shortest and the ... -
Evaluation on the Efect of Pressure Transients on Rock Joints in Unlined Hydropower Tunnels Using Numerical Simulation
(Peer reviewed; Journal article, 2021)Frequent pressure transients are identified as the cause of block failures in many unlined hydropower tunnels. The primary design objective of such tunnels is to prevent hydraulic jacking at design static pressure and mass ... -
Evaluation on the effect of glacier retreat for the development of deep seated slope deformation: Aletschglacier, Switzerland
(Master thesis, 2010)This master thesis investigates the development of a deep seated gravitational slope deformation (DSGSD) as a response to active glacier retreat. The instability is located in the Swiss Alps close to the tongue of the Great ... -
An Evaluation on the Impact of Ore Fragmented by Blasting on Mining Performance
(Peer reviewed; Journal article, 2022)In open-pit mines, the blast operation should be effectively optimized, leading to minimization of production costs through the application of specific technical specifications. However, there is inadequate information in ... -
Evaluation on the Potential Use of Shotcrete Lined High Pressure Tunnel at Upper Tamakoshi Hydroelectric Project
(Journal article; Peer reviewed, 2012)Optimization of rock support is a key for the successful use of underground space for hydropower development in the Himalaya. Therefore, finding innovative, optimum and economic solution will be the only way to guarantee ... -
Evaluation on the Squeezing Phenomenon at the Headrace Tunnel of Chameliya Hydroelectric Project, Nepal
(Master thesis, 2013)Growing demand of electricity in Nepal can be fulfilled by hydropower generation. The huge potentiality of hydropower generation in Nepal is mainly due to abundant water resources and available geographical head due to ... -
