The influence of Ammonia on the electrical properties of detonation nanodiamond
Detonation nanodiamonds (DNDs) are an interesting class of materials for sensing applications, but little is currently understood about their electrical properties. Here, aggregated DNDs are explored with impedance ...
Burst-polling based dynamic bandwidth allocation using adaptive minimum guaranteed bandwidth for EPONs
The enhanced burst-polling dynamic bandwidth allocation (EBDBA) method is proposed to support broadband access networks based on quality of service for Ethernet passive optical networks (EPONs). EBDBA adaptively increases ...
Average BER analysis of SCM-based free-space optical systems by considering the effect of IM3 with OSSB signals under turbulence channels
In this paper, we derive the average bit error rate (BER) of subcarrier multiplexing (SCM)-based free space optics (FSO) systems using a dual-drive Mach-Zehnder modulator (DD-MZM) for optical single-sideband (OSSB) signals ...
Integrated Wireless Optical Networking
The interoperability of wireless and PON topologies is investigated to reduce deployment expenditure by means of centralised network management while providing ubiquitous access connections and mobility. In addition, the ...
An investigation of stability of a control surface with structural nonlinearities in supersonic flow using Zubov's method
It is well known that the presence of nonlinearities may significantly affect the aeroelastic response of an aerospace vehicle structure. In this paper, the aeroelastic behaviour at high Mach numbers of an all-moving control ...
Numerical Simulation of charge stratifications to improve combustion and NO formation of lean-burn SI engines
The influences of charge stratification on spark ignition (SI) engine combustion and NO emission were analyzed using a phenomenological model. The mixture in the cylinder was divided spherically into three parts: a central ...
A method for the localization of damage in a CFRP plate using damping
In the past 25 years, the scientific and industrial communities have made great efforts on the fields of damage detection and structural health monitoring (SHM). However. no single approach has proven appropriate for all ...
On multi-objective optimization of geometry of staggered herringbone micromixer
A design methodology for micromixers is presented which systematically integrates computational fluid dynamics (CFD) with an optimization methodology based on the use of design of experiments (DOE), function approximation ...
