Performance Benchmarking of Stochastic and Deterministic Representation Bases with Compressive Sensing in Computerized Tomography Images
(2020-12-24)
Computerized tomography is a procedure that emits X-rays rotating around the body, projecting signals to be processed and converted to images. X-rays radiation in people may cause cardiovascular diseases, malformations in ...
An IDA-PBC Design with Integral Action for Output Voltage Regulation in an Interleaved Boost Converter for DC Microgrid Applications
(2021-12-29)
This paper describes the output voltage regulation control for an interleaved connected
to a direct current (DC) microgrid considering bidirectional current flows. The proposed controller
is based on an interconnection ...
Data-driven framework for the detection of non-technical losses in distribution grids
(2020-12-24)
Non-technical losses (NTL) occurring in the electric grid, particularly at the distribution level may cause a negative impact on utilities' interest, paying consumers and states. Reducing NTL can increase revenue, profit, ...
