A Hybrid Analytics Paradigm Combining Physics-Based Modeling and Data-Driven Modeling to Accelerate Incompressible Flow Solvers
(Journal article; Peer reviewed, 2018)Numerical solution of the incompressible Navier–Stokes equations poses a significant computational challenge due to the solenoidal velocity field constraint. In most computational modeling frameworks, this divergence-free ... -
A Hybrid Approach for Model Order Reduction of Barotropic Quasi-Geostrophic Turbulence
(Journal article; Peer reviewed, 2018)We put forth a robust reduced-order modeling approach for near real-time prediction of mesoscale flows. In our hybrid-modeling framework, we combine physics-based projection Methods with neural network closures to account ... -
A hybrid approach for solving real-world nurse rostering problems
(Journal article; Peer reviewed, 2011)Nurse rostering is the process of creating a plan for nurse working hours over a given time horizon. This problem, most variants of which are NP-hard, has been studied extensively for many years. Still, practical nurse ... -
A Lower Bound for the Node, Edge, and Arc Routing Problem
(Journal article; Peer reviewed, 2013)The Node, Edge, and Arc Routing Problem (NEARP) was defined by Prins and Bouchenoua in 2004, although similar problems have been studied before. This problem, also called the Mixed Capacitated General Routing Problem ... -
A Machine Vision System for Robust Sorting of Herring Fractions
(Journal article; Peer reviewed, 2016-07-16)Among the rest raw material in herring (Clupea harengus) fractions, produced during the filleting process of herring, there are high-value products such as roe and milt. As of today, there has been little or no major effort ... -
A mechanical and environmental assessment and comparison of basalt fibre reinforced polymer (BFRP) rebar and steel rebar in concrete beams
(Journal article; Peer reviewed, 2017)This paper compares holistically the mechanical and environmental performance of basalt fibre reinforced polymer (BFRP) rebar against conventional steel rebar in concrete beams. This assessment involves material testing ... -
A meta-analysis of plaice size-selection data in otter trawl codends
(Journal article; Peer reviewed, 2020-07)The influence that mesh size, the number of open meshes around the circumference, twine thickness and catch size have on the size-selection of plaice (Pleuronectes platessa) in otter trawl codends is investigated by ... -
A metaheuristic solution method for optimizing vessel fleet size and mix for maintenance operations at offshore wind farms under uncertainty
(Journal article; Peer reviewed, 2017-10)Maintenance operations at offshore wind farms are challenging due to the offshore element; maintenance technicians and spare parts need to be transported from an onshore port or offshore station to the individual wind farm ... -

A method for determining material's equivalent stress-strain curve with any axisymmetric notched tensile specimens without Bridgman correction
(Journal article; Peer reviewed, 2018) -
A Method for Developing Qualitative Security Risk Assessment Algorithms
(Journal article; Peer reviewed, 2018)We present a method for developing qualitative security risk assessment algorithms where the input captures the dynamic state of the target of analysis. This facilitates continuous monitoring. The intended users of the ... -
A method for simulating two-phase pipe flow with real equations of state
(Journal article; Peer reviewed, 2014)Common two-fluid models for pipe flow assume local non-equilibrium regarding phase transfer. To solve the two-fluid models together with accurate equations of state for real fluids will in most cases require mechanical, ... -
A Methodical Quantification of Needle Visibility and Echogenicity in Ultrasound Images
(Journal article; Peer reviewed, 2019)During ultrasound-guided percutaneous interventions, needle localization can be a challenge. To increase needle visibility, enhancements of both the imaging methods and the needle surface properties have been investigated. ... -
A methodology to improve the performance of PV integrated shading devices using multi-objective optimization
