Age replacement models: A summary with new perspectives and methods
(
Elsevier Ltd
, 2017 , Article Review)
Age replacement models are fundamental to maintenance theory. This paper summarizes our new perspectives and hods in age replacement models: First, we optimize the expected cost rate for a required availability level and ...
Multi-objective optimal design of hybrid renewable energy systems using PSO-simulation based approach
(
Elsevier Ltd
, 2014 , Article)
Recently, the increasing energy demand has caused dramatic consumption of fossil fuels and unavoidable raising energy prices. Moreover, environmental effect of fossil fuel led to the need of using renewable energy (RE) to ...
Evaluation of a novel greenhouse design for reduced cooling loads during the hot season in subtropical regions
(
Elsevier Ltd
, 2019 , Article)
Greenhouses provide an optimized growth environment for plants. However, providing this environment is energy intensive. In subtropical regions, most of this energy is to cater for the required cooling. The cooling demand ...
Morphological and structural properties of VoPcPhO:P3HT composite thin films
(
Elsevier
, 2016 , Article)
In this paper, we report the formation of VOPcPhO and P3HT composite nanostructures by spin-coating technique. Novel structural and morphological properties of the composite film have been observed at a specific volumetric ...
Simulation-Based Parametric Study for the Hybrid Superplastic Forming of AZ31
(
Elsevier B.V.
, 2019 , Conference Paper)
As the lightest constructional metal on earth, magnesium alloys offer excellent potential for weight reduction in the transportation industry and it was observed that some magnesium alloys exhibit superior ductility and ...
Finite element modelling and characterization of 3D cellular microstructures for the design of a cementless biomimetic porous hip stem
(
Elsevier Ltd
, 2018 , Article)
Titanium porous cellular microstructures are commonly used in bone mimetic implants. The orientations of the internal strut architectures of these microstructures affect the mechanical performance under various loads; ...
A framework based on location hazard index for optimizing operational performance of emergency response strategies: The case of petrochemical industrial cities
(
Elsevier B.V.
, 2019 , Article)
Emergency response operations are very important activities in the industrial areas. As an incident in an industrial area can have considerable economic and social impact, response to such an incident has to be provided ...
A novel axially half corrugated thin-walled tube for energy absorption under Axial loading
(
Elsevier Ltd
, 2019 , Article)
In this paper, tubes with different axial corrugations were studied under axial loading. Accordingly, a new axially half-corrugated thin-walled tube was developed to improve the energy absorption characteristics. The forming ...
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 ...
