A predictive model for the missing people problem
(2021-03-01)
The disappearance of people is a multidimensional phenomenon, in which several aspects must be considered. It affects people’s security perception and consumes police resources in its treatment. Therefore, does exists an ...
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 ...
Nonlinear control for a DC–DC converter with dual active bridges in a DC microgrid
(2022-10-29)
This work presents a new control strategy for a DC–DC converter with dual active bridges used to interconnect two feeders in a DC microgrid. The proposed control strategy allows regulating the output voltage of the converter ...
Optimal Integration of Photovoltaic Systems in Distribution Networks from a Technical, Financial, and Environmental Perspective
(2023-01-03)
Due to the increasing demand for electricity around the world, different technologies have been developed to ensure the sustainability of each and every process involved in its production, transmission, and consumption. ...
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, ...
