A novel time stamping data acquisition system using a digital oscilloscope for single counting photons
(Institute of Electrical and Electronics Engineers Inc., 2017-12)
In this paper we present an algorithm of signal processing that allows the use of a PC-based oscilloscope in order to count events with a time stamping register. This novel application has a direct use on recording of ...
Method to detect molecular ranges in elastic lidar signalMétodo para detectar rangos moleculares en señales lidar elásticas
(Sociedad Española de Óptica, 2017-09)
A method to detect aerosol plumes or clouds from an elastic lidar signal is presented, as well the determination of the atmospheric boundary layer height. It is based on the Rayleigh-fit concept, where the range-corrected ...
Female mate choice by chemical signals in a semi-terrestrial crab
(Elsevier Science, 2014-05)
Information about the roles of both sexes in pair formation is required to better understand the mechanisms involved in sexual selection. Mate choice could depend on the courtship behavior, involving chemical, tactile and ...
Measuring complexity of biomedical signals
(John Wiley & Sons Inc, 2018-09)
It is well known that biomedical signals, such as heart rate variability (HRV), electrocardiogram (ECG), electroencephalogram (EEG), and voice, arise from complex nonlinear dynamical systems, as the cardiovascular, nervous, ...
A new algorithm for epilepsy seizure onset detection and spread estimation from EEG signals
(IOP Publishing, 2016-04)
Appropriate diagnosis and treatment of epilepsy is a main public health issue. Patients suffering from this disease often exhibit different physical characterizations, which result from the synchronous and excessive discharge ...
A New Algorithm to Score Apnea/Hypopnea Events based on Respiratory Effort Signal and Oximeter Sensors
(Institute of Biomedical Engineering, 2020-08)
Purpose: The aim of this work is to develop and evaluate a new algorithm for the detection of Apnea/Hypopnea events based on the AASM recommendations, with low computational cost and using alternative sensors, such as the ...
A heuristic approach to obtain signal envelope with a simple software implementationUn método heurístico para obtener la envolvente de señal y su implementación de software
(Asociación Física Argentina, 2018-08)
Signal amplitude envelope allows to obtain information of the signal features for different applications. It is widely used to pre-process sound and other signals of physiological origin in human or animal studies. In order ...
Pipe-flange detection with GPR
(IOP Publishing, 2011-12)
This paper describes an application of the ground penetrating radar (GPR) method for detecting pipe flanges. A case history is described in which GPR was successfully used to locate pipe flanges along an 8 km metal pipeline, ...
Label-free electrochemical aptasensor for the detection of lysozyme
(Elsevier Science, 2009-04)
This work reports the advantages of a label free electrochemical aptasensor for the detection of lysozyme. The biorecognition platform was obtained by the adsorption of the aptamer on the surface of a carbon paste electrode ...
The shade-avoidance syndrome: Multiple signals and ecological consequences
(Wiley Blackwell Publishing, Inc, 2017-01)
Plants use photoreceptor proteins to detect the proximity of other plants and to activate adaptive responses. Of these photoreceptors, phytochrome B (phyB), which is sensitive to changes in the red (R) to far-red (FR) ratio ...
