Statistical modeling of Ship’s hydrodynamic performance indicator
(Peer reviewed; Journal article, 2021)The traditional method used to estimate the hydrodynamic performance of a ship uses either the model test results or one of the many empirical methods to estimate and observe the trend in fouling friction coefficient () ... -
Anisotropic Plasticity and Fracture of Three 6000-Series Aluminum Alloys
(Peer reviewed; Journal article, 2021)The influence of microstructure on plasticity and fracture of three 6000-series aluminum alloys is studied with emphasis on the anisotropy caused by the extrusion process. Tension tests on smooth and notched specimens are ... -
Cascaded Organic Rankine Cycles (ORCs) for Simultaneous Utilization of Liquified Natural Gas (LNG) Cold Energy and Low-Temperature Waste Heat
(Peer reviewed; Journal article, 2020)Liquified Natural Gas (LNG) is a good way to transport natural gas from suppliers to end consumers. LNG contains a huge amount of cold energy due to the energy consumed in the liquefaction process. Generally, the LNG cold ... -
Interface Microstructure and Tensile Properties of a Third Generation Aluminium-Steel Butt Weld Produced Using the Hybrid Metal Extrusion & Bonding (HYB) Process
(Peer reviewed; Journal article, 2021)The Hybrid Metal Extrusion & Bonding (HYB) process is a patented solid state joining method for metals which utilizes filler material additions to consolidate the weld. In the present investigation the interface microstructure ... -
Effect of T-groove Parameters on Steady-State Characteristics of Cylindrical Gas Seal
(Peer reviewed; Journal article, 2020)Gas film seal technology is becoming increasingly important as an advanced new rotary shaft seal technology in aviation engines and industrial gas turbines. In this paper the impacts of several parameters of T-groove ... -
Chemical Potential Differences in the Macroscopic Limit from Fluctuations in Small Systems
(Peer reviewed; Journal article, 2021)We present a new method for computing chemical potential differences of macroscopic systems by sampling fluctuations in small systems. The small system method, presented by Schnell et al. [Schnell et al., J. Phys. Chem. ... -
The effect of Stefan flow on Nusselt number and drag coefficient of spherical particles in non-isothermal gas flow
(Peer reviewed; Journal article, 2021)A Stefan flow can be generated during a phase change or reactions of a particle immersed in a fluid. This study investigates the effect of Stefan flow on the exchange of momentum (drag coefficient (CD)) and heat transfer ... -
Coupling of dynamic reaction forces of a heavy load crane and ship motion responses in waves
(Peer reviewed; Journal article, 2021)The conventional approach to dynamic analysis of ship motion response with shipboard operation equipment is usually done by establishing combined equations of motion of the multi-body system. The weakness of such methods ... -
A Multi-Analytical Approach for the Characterization of Seventeenth Century Decorative Wall Paintings in Two Norwegian Stave Churches: A Case Study at Eidsborg and Heddal, Norway
(Peer reviewed; Journal article, 2021)The presented research examines 17th century distemper paint from the polychrome wooden interiors of two Norwegian stave churches: Eidsborg and Heddal. For the first time, the inorganic and organic components of specimens ... -
A Survey of Eye Tracking in Automobile and Aviation Studies: Implications for Eye-Tracking Studies in Marine Operations
(Peer reviewed; Journal article, 2021)In the last decade researchers have increasingly considered eye tracking of the operators of cars and airplanes as a means to address human error and evaluate operational effectiveness. This article presents a systematic ... -
Performance of a Linear Solution for Approximating Nonlinear Response of Reinforced Concrete Structures Subjected to Earthquake Shaking
(Chapter, 2020)Nonlinear Time History Analyses (NTHA) are generally regarded as the most accurate way of predicting the dynamic response of a structure to a given seismic ground motion. However, these types of analyses are computationally ... -
Applicability of ERP for Production Network Planning: A Case Study
(Chapter, 2014)A production network enables a company to develop capabilities to respond to diversity in national or regional demand, while at the same time integrate and coordinate their activities. Many companies have implemented ... -
A novel monitoring and modelling technique for energy-related occupant behaviour
