Wear resistance investigation of titanium nitride-based coatings
(
Elsevier Ltd
, 2015 , Article)
The wear of components while they are in service is a predominant factor controlling the life of machine components. Metal parts are often damaged because of wear-driven failures causing the loss of dimensions and ...
Effect of microstructural evolution on wettability and tribological behavior of TiO2 nanotubular arrays coated on Ti–6Al–4V
(
Elsevier Ltd
, 2015 , Article)
Self-organized TiO2 nanotubular arrays were fabricated by electrochemical anodization of Ti–6Al–4V plates in an NH4F/H3PO4 electrolyte. The effect of microstructural evolutions on the wettability and tribological behavior ...
TiO2 nanotube coating on stainless steel 304 for biomedical applications
(
Elsevier Ltd
, 2015 , Article)
The present study describes the anodic growth of TiO2 nanotube thin layer on stainless steel 304 in ethylene glycol/water/ammonium fluoride electrolyte. In this regard, pure titanium was coated on stainless steel 304 ...
Spiderweb Honeycombs
(
Elsevier Ltd
, 2015 , Article)
Small and large deformation in-plane elastic response of a new class of hierarchical fractal-like honeycombs inspired by the topology of the “spiderweb” were investigated through analytical modeling, detailed numerical ...
Optimal design of hybrid renewable energy systems in buildings with low to high renewable energy ratio
(
Elsevier Ltd
, 2015 , Article)
We develop a simulation-based meta-heuristic approach that determines the optimal size of a hybrid renewable energy system for residential buildings. This multi-objective optimization problem requires the advancement of a ...
A hybrid optimization-simulation approach for robust weekly aircraft routing and retiming
(
Elsevier Ltd
, 2017 , Article)
We address the robust weekly aircraft routing and retiming problem, which requires determining weekly schedules for a heterogeneous fleet that maximizes the aircraft on-time performance, minimizes the total delay, and ...
Dynamic aggregated building electricity load modeling and simulation
(
Elsevier B.V.
, 2014 , Article)
In order to support the growing interest in demand response modeling and analysis, there is a need for physical-based building load models. This work presents a new approach for simulating electrical power flow in buildings. ...
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 ...
