A practical solution approach for the green vehicle routing problem
(
Elsevier Ltd
, 2017 , Article)
Green vehicle routing (GVRP) is an active research area that is concerned with the development and analysis of distribution activities with eco-friendly vehicles. We propose a practical solution approach for the GVRP that ...
Tidal power technology review with potential applications in Gulf Stream
(
Elsevier Ltd
, 2017 , Article Review)
With the increasing concern of global warming, the importance of reducing greenhouse gas emissions has been accepted worldwide. Realizing the contribution of conventional energy sources to greenhouse gas emissions and the ...
Elastic properties of chiral, anti-chiral, and hierarchical honeycombs: A simple energy-based approach
(
Elsevier Ltd
, 2016 , Article)
The effects of two geometric refinement strategies widespread in natural structures, chirality and self-similar hierarchy, on the in-plane elastic response of two-dimensional honeycombs were studied systematically. Simple ...
A model and optimization-based heuristic for the operational aircraft maintenance routing problem
(
Elsevier Ltd
, 2016 , Article)
This paper investigates the Operational Aircraft Maintenance Routing Problem (OAMRP). Given a set of flights for a specific homogeneous fleet type, this short-term planning problem requires building feasible aircraft routes ...
Comparisons of replacement policies with periodic times and repair numbers
(
Elsevier Ltd
, 2017 , Article)
Periodic replacement policies modeled with the history of minimal repairs have been studied extensively. However, in the viewpoint of cost rate, there is no literature to compare replacement polices which are carried out ...
Joint optimization of redundancy level and spare part inventories
(
Elsevier Ltd
, 2016 , Article)
We consider a "k-out-of-N"? system with different standby modes. Each of the N components consists of multiple part types. Upon failure, a component can be repaired within a certain time by switching the failed part by a ...
Effects of electron acceptors on removal of antibiotic resistant Escherichia coli, resistance genes and class 1 integrons under anaerobic conditions
(
Elsevier B.V.
, 2016 , Article)
naerobic biotechnologies can effectively remove antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARGs), but there is a need to better understand the mechanisms. Here we employ bioelectrochemical systems ...
An optimal two-bout strategy with phase change material cooling vests to improve comfort in hot environment
(
Elsevier Ltd
, 2018 , Article)
Cooling vests incorporating phase change material (PCM) packets are used to improve comfort of workers in hot environments. This work aims to investigate by modeling and experimentation the effect of dividing the working ...
The role of statistics in data-centric engineering
(
Elsevier B.V.
, 2018 , Article)
We explore the role of statistics for Big Data analysis arising from the emerging field of Data-Centric Engineering. Using examples related to sensor-instrumented bridges, we highlight a number of issues and challenges. ...
Sensorless sliding mode observer for a five-phase permanent magnet synchronous motor drive
(
Elsevier
, 2015 , Article)
This paper deals with the sensorless vector controlled five-phase permanent magnet synchronous motor (PMSM) drive based on a sliding mode observer (SMO). The observer is designed considering the back electromotive force ...
