On the optimal computing budget allocation problem for large scale simulation optimization
(
Elsevier B.V.
, 2017 , Article)
Selecting a set that contains the best simulated systems is an important area of research. When the number of alternative systems is large, then it becomes impossible to simulate all alternatives, so one needs to relax the ...
Fabrication and characterization of size-selected Cu nanoclusters using a magnetron sputtering source
(
Elsevier B.V.
, 2018 , Article)
Copper nanoclusters are used widely in applications such as glucose and gas sensors. A physical method is used to produce copper nanoclusters utilizing an ultra-high vacuum (UHV) system. Using a quadrupole mass filter ...
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 ...
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 ...
Acute mercury toxicity modulates cytochrome P450, soluble epoxide hydrolase and their associated arachidonic acid metabolites in C57Bl/6 mouse heart
(
Elsevier Ireland Ltd.
, 2014 , Article)
Mercury exposure is associated with increased risk of cardiovascular disease and profound cardiotoxicity. However, the correlation between Hg2+-mediated toxicity and alteration in cardiac cytochrome P450s (Cyp) and their ...
Expression of sperm PLC? and clinical outcomes of ICSI-AOA in men affected by globozoospermia due to DPY19L2 deletion
(
Elsevier Ltd
, 2018 , Article)
Globozoospermia is characterized by the presence of 100% acrosomeless round-headed spermatozoa in an ejaculate. Failed fertilization after intracytoplasmic sperm injection (ICSI) is commonly reported for globozoospermic ...
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 ...
Editorial: What Are the Challenges in Conducting Cost-of-Illness Studies?
