Localized harmonic motion imaging
(2012-11-10)
Localized Harmonic Motion (LHM) Imaging is a new technique of ultrasound imaging which uses the localized stimulus of the oscillatory ultrasonic radiation force as produced by a modulated signal, and estimates the resulting ...
Speed sensorless and MPPT control of IPM synchronous generator for wind energy conversion system
(2014-01-22)
The popularity of renewable energy has experienced significant growth recently due to
the foreseeable exhaustion of conventional fossil fuel power generation methods and increasing realization of the adverse effects that ...
Vision-based control and autonomous landing of a VTOL-UAV
(2015-10-21)
In recent years the popularity of quadrotor unmanned aerial vehicles (UAVs) has increased. Today, UAVs are widely used by military and police forces for surveillance. They are used by industry for such tasks as traffic ...
Peak power analysis of MC-CDMA employing Golay complementary sequences
(2012-11-10)
l\!Iulticarrier code division multiple access (MC-CDMA) combines
both orthogonal frequency division multiplexing (OFDM) and code
division multiple access (CD lVIA) techniques. It inherits the advantages
of these two ...
A device for performing sonoporation on adherent cell cultures
(2015-06-15)
Sonoporation is a method for inducing a transient increase in the permeability of cell
membranes to otherwise impermeable compounds using ultrasound. This technique has
therapeutic potential as it allows for localized ...
Dynamic resource allocation algorithms for long term evolution (LTE) wireless broadband networks
(2014-01-22)
Following the successful standardization of High-Speed Packet Access (HSPA), the 3rd Generation Partnership Project (3GPP) recently specified the Long Term Evolution (LTE) as a next generation radio network technology to ...
Modeling of a high frequency field effect transitor on indium gallium nitride: the metal oxide semiconductor capacitor 1=channel model
(2012-11-10)
Quantum devices are an important class of modern heterostructure devices in which quantum effects are exploited directly. A Gallium Nitride high frequency field effect transistor (FET), the subject of this work, exploits ...
Control of doubly fed induction generator based wind energy conversion system
(2014-01-22)
The doubly fed induction generator (DFIG) is widely used in today’s wind energy conversion industry. The DFIG is essentially a wound rotor induction generator in which the rotor circuit can be controlled by external devices ...
Fuzzy logic based efficiency optimization of IPM synchronous motor drive
(2012-11-10)
Interior permanent magnet synchronous motor (IPMSM) is highly appreciated by
researchers in variable speed drive applications due to some of its advantageous features
such as small size, high power density, simple ...
Empirical recovery performance of fourier-based deterministic compressed sensing
(2014-01-22)
Compressed sensing is a novel technique where one can recover sparse signals from the undersampled measurements. Mathematically, measuring an N-dimensional signal...
