High-performance removal of toxic phenol by single-walled and multi-walled carbon nanotubes: Kinetics, adsorption, mechanism and optimization studies
(
Korean Society of Industrial Engineering Chemistry
, 2016 , Article)
The adsorption capabilities of two nano-sized adsorbents: multi-walled carbon nanotubes (MWCNTs) and single-walled carbon nanotubes (SWCNTs) were investigated for the removal of toxic phenol. The maximum adsorption capacities ...
Joint optimal threshold-based relaying and ML detection in cooperative networks
(
IEEE
, 2012 , Article)
This paper proposes two detection schemes for cooperative networks comprising a source, a relay and a destination. The relay is assumed to operate in a half-duplex mode and it employs decode-and-forward (DF) relaying. The ...
Utility-based efficient dynamic distributed resource allocation in buffer-aided relay-assisted OFDMA networks
(
Springer International Publishing
, 2015 , Article)
In this paper, we study resource allocation in buffer-aided relay-assisted OFDMA networks. We consider utility-based stochastic optimization framework where there are constraints to be met either instantaneously or in ...
Efficient Usage of Renewable Energy in Communication Systems Using Dynamic Spectrum Allocation and Collaborative Hybrid Powering
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Article)
In this paper, we introduce a new green resource allocation problem using hybrid powering of communication systems from renewable and nonrenewable sources. The objective is to efficiently allocate the power delivered from ...
Optimization of nickel oxide nanoparticle synthesis through the sol-gel method using Box-Behnken design
(
Elsevier BV
, 2015 , Article)
In this study, nickel oxide nanoparticles were prepared using the sol-gel method. The process parameters were optimized to produce smaller size of nanoparticles such as molar ratio, solution pH and calcination temperatures. ...
Strength optimisation of mortar with CNTs and nanoclays
(
Thomas Telford Services Ltd
, 2016 , Article)
This study explores the use of carbon nanotubes (CNTs) and nanoclays in cement mortars. The paper presents modelling and optimisation of the compressive and flexural strengths of cement mortars containing CNTs and the ...
A dynamic MOPSO algorithm for multiobjective optimal design of hybrid renewable energy systems
(
John Wiley and Sons Ltd
, 2014 , Article)
In this paper, a dynamic multiobjective particle swarm optimization (DMOPSO) method is presented for the optimal design of hybrid renewable energy systems (HRESs). The main goal of the design is to minimize simultaneously ...
Differential evolution-based pulse-width modulation technique for multiphase MC
(
Institution of Engineering and Technology
, 2019 , Article)
This paper addresses multiphase matrix converter (MPMCs) modulated with Venturini's classical scalar approach. The solution to obtain time-varying modulation functions was limited to 3 × 3 configuration, which was later ...
Characteristics-based model predictive control of selective catalytic reduction in diesel-powered vehicles
(
Elsevier Ltd
, 2016 , Article)
In heavy-duty diesel exhaust systems, selective catalytic reduction (SCR) is used to reduce NOx to nitrogen to meet environmental regulations. Diesel exhaust after-treatment involves a set of components that are best ...
Optimal utilization of geothermal heat from abandoned oil wells for power generation
(
Elsevier Ltd
, 2019 , Article)
Unlike other types of renewable energy, geothermal resources represent a stable energy source because they can be exploited regardless of meteorological conditions. In geothermal systems, heat is exchanged between the ...
