A high sensitivity single-probe heat pulse soil moisture sensor based on a single npn junction transistor
(Elsevier Sci LtdOxfordInglaterra, 2013)
Giant Chemo-Resistance of SnO disk-like structures
(2013-07-03)
Single crystalline SnO micro-disks, synthesized by a carbothermal reduction process, exhibited a nearly 1000-fold increase in resistance upon exposure to 100 ppm of NO2 without addition of catalysts or dopants nor the ...
Low-cost control and measurement circuit for the implementation of single element heat dissipation soil water matric potential sensor based on a SnSe2 thermosensitive resistor
(2021-02-02)
A low-cost signal processing circuit developed to measure and drive a heat dissipation soil matric potential sensor based on a single thermosensitive resistor is demonstrated. The SnSe2 has a high thermal coefficient, from ...
Localized ant colony of robots for redeployment in wireless sensor networks
(Old City PublishingPhiladelphia, 2014)
Sensor failures or oversupply in wireless sensor networks (WSNs), especially initial random deployment, create spare sensors (whose area is fully covered by other sensors) and sensing holes. We envision a team of robots ...
A Gas Sensor Based on a Single SnO Micro-Disk
(Mdpi, 2018-10-01)
In this study, individual nanofabricated SnO micro-disks, previously shown to exhibit exceptional sensitivity to NOx, are investigated to further our understanding of gas sensing mechanisms. The SnO disks presenting different ...

Single crystalline SnO micro-disks, synthesized by a carbothermal reduction process, exhibited a nearly 1000-fold increase in resistance upon exposure to 100 ppm of NO2 without addition of catalysts or dopants nor the ...
Single-observer based current sensor fault tolerant control for IM traction drives
(Institute of Electrical and Electronics Engineers, 2021-12)
In this work, a current sensors fault tolerant control system (FTCS) for induction motor traction drives is proposed. The FTCS uses a single observer for the detection and isolation of disconnection and gain faults occurred ...
Smart Readout of Nondestructive Image Sensors with Single Photon-Electron Sensitivity
(American Physical Society, 2021-12)
Image sensors with nondestructive charge readout provide single-photon or single-electron sensitivity, but at the cost of long readout times. We present a smart readout technique to allow the use of these sensors in visible ...
