Measures, performance assessment, and enhancement of TFDs
(
Elsevier Inc.
, 2016 , Book chapter)
This chapter describes a number of time-frequency (t,f) performance quality measures specifically developed as criteria for performance enhancement for a given application. The adopted performance measures are defined using ...
Effects of environmental and climatic conditions on PV efficiency in qatar
(
European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ)
, 2013 , Article)
The sensitivity of various solar photovoltaic technologies towards dust, temperature and relative humidity is investigated for Qatar’s environment. Results obtained show that dust accumulation has the great effect on ...
A full bridge-based fault current controller for distributed generation systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Nowadays the demand of electricity is continuously increasing which necessitates adding more distributed generators, causing the level of fault current to highly increase. The level of Fault Current (FC) could even exceed ...
Contribution of Shell Eco-Marathon engineering design experience to soft skills development: A qualitative analysis in the Asian context
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Recent studies emphasize the needs of a wider set of skills engineers require than ever thought. Engineering curricula have been frequently criticized. Engineering design experience is one remedial way of heavy theory ...
Torque ripple reduction of radial magnetic gearbox using axial pole pairing
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
Magnetic gearbox (MGB) is a contactless magnet-based transmission system that transmits mechanical power between two shafts. MGBs offer significant advantages over mechanical gears such as contactless power transfer, high ...
Bidirectional buck-boost inverter-based HVDC transmission system with AC-side contribution blocking capability during DC-side faults
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
Offshore wind energy is now seen as a key contributor for the future renewable energy mix. HVDC technology is among the chief technologies enabling widespread use of offshore wind. Thanks to their numerous advantages, ...
Sequential random selection relaying for energy efficient wireless sensor networks
(
IEEE
, 2010 , Conference Paper)
In a wireless sensor network with relaying capability, intermediate relay nodes are with limited energy budget. To maximize lifetime of relay nodes, selective relay strategies, requiring full channel state information ...
Sparsity-Aware multiple relay selection in large dual-hop decode-And-forward broadband relay networks
(
IEEE
, 2016 , Conference Paper)
In this paper, three novel techniques are proposed and investigated for multiple relay selection in dual hop OFDM networks. These techniques are based on the exploitation of sparse signal recovery theory and on carefully-designed ...
Ultra-high aspect ratio copper nanowires as transparent conductive electrodes for dye sensitized solar cells
(
SPIE
, 2016 , Conference Paper)
We report the synthesis of ultra-high aspect ratio copper nanowires (CuNW) and fabrication of CuNW-based transparent conductive electrodes (TCE) with high optical transmittance (>80%) and excellent sheet resistance (Rs <30 ...
On the statistical distribution of electric field inside jet engines
(2013 , Conference Paper)
Using full wave analysis in 'Ansys HFSS', we obtain the electric field distribution inside a jet engine containing one set of 24 blades due to the excitation provided by a simple Hertzian dipole. Hertzian dipole illuminates ...
