HVDC shunt tap based on series-input parallel-output DC-AC multi-module VSCs with DC voltages balancing
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
Conventionally, tapping-off a small amount of power from an HVDC transmission line to a three-phase local network can be achieved using a DC-to-AC voltage source converter (VSC) followed by a step down transformer. In order ...

The continuous advancement in computer and communication technologies has made personalized healthcare monitoring a rapidly growing area of interest. New features and services are envisaged, raising users' expectations in ...
Nanocomposite Ni-TiO2 coatings produced by pulsed electroplating
(
Maney Publishing
, 2014 , Conference Paper)
Nanocomposite Ni-TiO2 coatings were prepared on mild steel substrate by pulse electroplating with controlled duty cycle and frequency. A systematic study of Ni-xTiO2 coatings with different TiO2 concentrations (x50-20 g ...
Cost effective assessment of transformers using machine learning approach
(
IEEE Computer Society
, 2014 , Conference Paper)
Furan content in transformer oil is highly correlated with the transformer insulation paper aging. In this paper, the ranges of furan content in power transformer is predicted using measurements of transformer oil tests ...

A Simple channel modeling method based on correlation analysis of the electric field inside jet engine is presented. The analysis of the statistical propagation characteristics of electromagnetic field inside harsh jet ...
Hybrid underlay/overlay cognitive radio system with hierarchical modulation in the presence of channel estimation error
(
IEEE
, 2014 , Conference Paper)
In this paper, we study the performance of hybrid cognitive radio (CR) system in the presence of channel estimation error (CER) in terms of bit-error-probability (BEP) and outage probability. We assume simultaneous switching ...
Sol-gel synthesis of nanocrystalline Ni-ferrite and Co-ferrite redox materials for the rmoche mical production of solar fuels
(
Materials Research Society
, 2014 , Conference Paper)
In this contribution, we report the synthesis and characterization of NixFe3-xO4 and CoxFe3-xO4 redox nanomaterials using sol-gel method. These materials will be used to produce solar fuels such as H2 or syngas from H2O ...
Maximum throughput of a secondary user cooperating with an energy-aware primary user
(
IEEE Computer Society
, 2014 , Conference Paper)
This paper proposes a cooperation protocol between a secondary user (SU) and a primary user (PU) which dedicates a free frequency subband for the SU if cooperation results in energy saving. Time is slotted and users are ...
A stationary frame current control for inverter-based distributed generation with sensorless active damped LCL filter using Kalman filter
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Due to the large variety of renewable power sources, power electronics play an important role in energy conversion. Different power converter topologies are used to interface distributed power generation systems (DPGS) ...
Robust cooperative control reconfiguration/recovery in multi-agent systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
In this paper, a reconfigurable control protocol for a linear multi-agent system seeking consensus in presence of actuator faults and saturations and environmental disturbances is investigated. Two controllers, namely the ...
