A context-aware approach for long-term behavioural change detection and abnormality prediction in ambient assisted living
( Elsevier , 2015 , Article)This research aims to describe pattern recognition models for detecting behavioural and health-related changes in a patient who is monitored continuously in an assisted living environment. The early anticipation of anomalies ... -
A control algorithm to increase the efficient operation of wind energy conversion systems under extreme wind conditions
( Elsevier , 2022 , Article)This paper aims to increase the power production of gearless permanent magnet synchronous generator (PMSG) based wind energy conversion systems (WECS) in strong (greater than 25 m/s) wind speed regions. In general, most ... -
A critical review of the development and demulsification processes applied for oil recovery from oil in water emulsions
( Elsevier , 2022 , Article)The formation of stable emulsions is a fundamental problem in oil industry that can result in a sequence of environmental and operational problems. Chemical demulsification is extensively applied for the recovery of oil ... -
A decision support system for automating document retrieval and citation screening
( Elsevier , 2021 , Article)The systematic literature review (SLR) process includes several steps to collect secondary data and analyze it to answer research questions. In this context, the document retrieval and primary study selection steps are ... -
A fouling suppression system in submerged membrane bioreactors using dielectrophoretic forces
( Elsevier , 2015 , Article)A novel method was developed to suppress membrane fouling in submerged membrane bioreactors. The method is based on the dielectrophoretic (DEP) motion of particles in an inhomogeneous electrical field. Using a real sample ... -
A high step-up DC-DC converter based on ASL and VMC for renewable energy applications
( Elsevier , 2022 , Article)In this paper, a new high step-up non-isolated DC-DC converter has been proposed and analyzed. The proposed topology provides a high DC output voltage, which is adjustable by two different duty cycles. Moreover, low voltage ... -
A hybrid piezoelectric-electromagnetic energy harvester from vortex-induced vibrations in fluid-flow; the influence of boundary condition in tuning the harvester
( Elsevier , 2022 , Article)In this paper, a hybrid piezoelectric-electromagnetic energy harvester is proposed to harvest energy from fluid flow around a bluff-body using vortex-induced vibration (VIV). The hybrid piezoelectric-electromagnetic harvester ... -
A hybrid simulation-optimization approach for the robust Discrete Time/Cost Trade-off Problem
( Elsevier , 2015 , Article)We investigate a stochastic Discrete Time/Cost Trade-off Problem. This multimode project scheduling problem, requires assigning modes to activities, and scheduling the activities so that the sum of the activities cost and ... -
A longitudinal analysis of the effect of maternal region-of-birth on transitions in children's bodyweight status from early childhood to late adolescence in Australia: A population-based cohort study
( Elsevier , 2021 , Article)Although 49% of Australian residents have at least one overseas-born parent, little is known about children's longitudinal bodyweight transitions among the migrant population. This study examines the net associations between ... -
A matheuristic for the robust integrated airline fleet assignment, aircraft routing, and crew pairing problem
( Elsevier , 2022 , Article)We address an integrated airline scheduling problem that combines three airline planning processes: fleet assignment, aircraft routing, and crew pairing. For a given daily flight schedule, the problem requires simultaneously ... -
