A Comparative Study on Apprenticeship Systems Using Agent-Based Simulation
(Peer reviewed; Journal article, 2022)In this paper, we investigate the effects of different characteristics of apprenticeship programmes both in historical and contemporary societies. Apprenticeship is one of the major means to transfer skills in a society. ... -
Comparative Study On Dynamic Responses of a Semi-submersible Wind Turbine Using a Simplified Aerodynamic Model and a BEM Model
(Master thesis, 2013)Due to the high potential of offshore wind energy, a lot of research work is being done around the world on offshore wind turbines. Currently mainly two types of model are used in Marine Technology Department of NTNU to ... -
A comparative study on quality, shelf life and sensory attributes of Atlantic salmon slaughtered on board slaughter vessels against traditional land-based facilities.
(Peer reviewed; Journal article, 2021)The purpose of this study was to investigate the shelf life and quality of Atlantic salmon (Salmo salar) slaughtered onboard vessels and shipped to Denmark in −0.8 °C refrigerated seawater (RSW) as compared to traditional ... -
A comparative study on the dynamic behaviour of 10 MW conventional and compact gearboxes for offshore wind turbines
(Peer reviewed; Journal article, 2020)This study compares the dynamic behaviour of a conventional and a compact gearbox for the DTU 10 MW wind turbine supported on a monopile offshore structure. The conventional gearbox configuration is composed of two planetary ... -
Comparative study on the dynamic response of a Spar type buoy and a Sevan type cylinder floating production unit
(Master thesis, 2012)Comparative study on the dynamic response of a Spar type buoy and a Sevan type cylinder floating production unit -
A comparative study on the effect of hot/wet and hot/dry aging environments on the degradation of filament winded composites
(Chapter, 2022)Predicting the long-term response of polymer composite materials is a continuous challenge to the composite industry. The service aging of structural composites has different effects on composites’ physicochemical behavior ... -
Comparative study on the photocatalytic hydrogen producton from methanol over Cu, Pd, Co and Au loaded TiO2
(Peer reviewed; Journal article, 2015)Photocatalytic hydrogen production from a methanol-water solution was investigated in a semi-continuous reactor over different metal-loaded TiO2 catalysts under UltraViolet (UV) light irradiation. The catalysts were mainly ... -
Comparative study on the thermal behavior of untreated and various torrefied bark, stem wood, and stump of Norway spruce
(Journal article; Peer reviewed, 2017)In this work, the torrefaction of different parts of Norway spruce (stem wood, bark, and stump) was studied. Three different torrefaction temperatures were applied: 225, 275, and 300 °C with 30 and 60 min isothermal periods. ... -
A Comparative Study on the Wind Deflection of Railway Overhead Contact Line Based on Empirical Formula and Finite Element Approach
(Journal article; Peer reviewed, 2021) -
Comparative study on various dielectric barriers and their effect on breakdown voltage
(Journal article; Peer reviewed, 2018)Non-pressurised air is extensively used as basic insulation medium in high-voltage equipment. Unfortunately, an inherent property of air-insulated design is that the system tends to become physically large. On the other ... -
A comparative study to investigate two configurations of a two-stage evaporator in a CO2 heat pump chiller
(Chapter, 2023)This study is carried out to investigate the performance of a CO2 heat pump chiller that provides heating and cooling simultaneously. For heating applications, hot water is produced at 90°C; while for cooling applications, ... -
Comparative testing and evaluation of nine different air samplers: End-to-end sampling efficiencies as specific performance measurements for bioaerosol applications
