Skin color independent robust assessment of capillary refill time
Raquel Pantojo de Souza Bachour, Eduardo Lopes Dias, George Cunha Cardoso
Capillary refill time (CRT) is a method for evaluating peripheral perfusion by visual assessment. CRT is especially useful for quick evaluations in the absence of sophisticated equ…
Skin optical attenuation coefficient modulation with arterial pulsation
Matheus Bigatão Martinelli, Christian Tolentino Dominguez, Luciano Bachmann +1
Video plethysmographic (vPPG) signals arise from subtle color modulations in reflected light. vPPG signals can be used to monitor vital signs remotely in a noninvasive manner. We h…
Blood Pulsation Intensity Video Mapping
Pedro Henrique de M. Borges, George C. Cardoso
In this study, we make non-invasive, remote, passive measurements of the heart beat frequency and determine the map of blood pulsation intensity in a region of interest (ROI) of sk…
Method to study student engagement uniformity in a classroom
George C. Cardoso
We present a method to study engagement level uniformity in a class of students. We validate our method by comparing two semesters taught using different methods in a physics and m…
A battery-resistor analogy for further insights on measurement uncertainties
Gabriel L. A. de Sousa, George C. Cardoso
We use analogies to give introductory laboratory students intuition about measurement uncertainties. Using a battery-resistor circuit we discuss uncertainty concepts and derive exp…
In-Situ absolute phase detection of a microwave field via incoherent fluorescence
George C. Cardoso, Prabhakar Pradhan, Jacob Morzinski +1
Measuring the amplitude and the absolute phase of a monochromatic microwave field at a specific point of space and time has many potential applications, including precise qubit rot…
