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 ...
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 ...
Optimization of chiral lattice based metastructures for broadband vibration suppression using genetic algorithms
(
Academic Press
, 2016 , Article)
One of the major challenges in civil, mechanical, and aerospace engineering is to develop vibration suppression systems with high efficiency and low cost. Recent studies have shown that high damping performance at broadband ...
Relay selection schemes to minimise outage in wireless powered communication networks
(
Institution of Engineering and Technology
, 2016 , Article)
In this study, the authors discuss relay selection schemes with the objective to minimise outage probability for a network consisting of a single source, multiple relays and a single destination. The relays are powered by ...
Calculation of derating factors based on steady-state unbalanced multiphase induction machine model under open phase(s) and optimal winding currents
(
Elsevier
, 2014 , Article)
Multiphase machines have become a promising candidate in high-power applications as they offer many advantages over their three-phase counterparts. The main salient feature is the high fault tolerance capability. During ...
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 ...
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 ...
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 ...
A mathematical model for carbon fixation and nutrient removal by an algal photobioreactor
(
Elsevier Ltd
, 2016 , Article)
A comprehensive mathematical modeling method for Chlorella vulgaris (Cv) has been developed to assess the influence of nutrient concentration (total nitrogen TN= 28-207 and total phosphorus TP= 6-8mgL 1) and irradiation ...
