Ku band rotary traveling-wave voltage controlled oscillator
(2021)
Voltage-controlled oscillator (VCO) plays a key role in determination of the link
budget of wireless communication, and consequently the performance of the transceiver.
Lowering the noise contribution from the VCO to the ...
Gallium nitride on low temperature cofired ceramic templates for Schottky junctions
(2021)
In this work aluminum, silicon and zinc oxide were used as intermediate layers for thin
film growth on cofired glass ceramic substrates. The motivation behind this work is a direct
deposition of nitride thin films on the ...
Compact magnetic resonance-guided high-intensity focused ultrasound phased array system
(2021)
Phased array ultrasound transducers (Txs) can induce electronically controllable localized
hyperthermia to tissue deep within the human body. This localized heating can be applied to
tumours as an adjunct therapy in ...
Performance investigation of H control and port controlled Hamilton with dissipation based nonlinear control for IPMSM drives
(2018-03-13)
Within the field of electrical drive systems, there has been increasing popularity
in the use of permanent magnetic synchronous machines as an execution unit, and the cooperation
with high performance control strategy. ...
Application of artificial intelligence in fault detection and classification of solar power plants and prediction of power generation of combined cycled power plants
(2022)
Solar energy is one of the most dependable renewable energy technologies, as it is feasible
almost everywhere globally and is environmentally friendly. Photovoltaic-based renewable energy
systems are highly susceptible ...
Efficient channel allocation schemes for multi-band relay networks
(2022)
As next generation wireless and mobile networks continue to evolve, the scarcity of frequency spectrum and bandwidth are on the rise. While ultra-dense small-scale networks
aim to satisfy the demand for ultra-high data ...
Power loss investigation of series-connected current source inverters
(2021)
Current-source inverters (CSIs) are a type of direct current (DC) to alternating current
(AC) converters that generate a defined AC output current waveform from a DC current
supply. As the counterpart of voltage source ...
Intelligent and cost-effective protection schemes for improved reliability of large-scale wind farms
(2021)
Recently, wind power has become a reliable and cost-effective renewable energy source of
electricity due to the foreseeable exhaustion of fossil fuel-based power generations and its growing
adverse effects on the environment ...
A smart monitoring system for bearing fault detection
(2022)
Rolling element bearings are commonly used in rotating machinery to support shafts,
reduce friction, and increase power transmission efficiency. For a machinery system, bearing
fault could be the most possible cause of ...
Holistic resource management in UAV-assisted wireless networks
(2022)
Unmanned aerial vehicles (UAVs) are considered as a promising solution to assist terrestrial networks in future wireless networks (i.e., beyond fifth-generation (B5G) and sixth-generation (6G)).
The convergence of various ...
