Single-pixel imaging of the retina through scattering media
(Optical Society of America, 2019)
Imaging the retina of cataractous patients is useful to detect pathologies before the cataract surgery is performed. However, for conventional ophthalmoscopes, opacifications convert the lens into a scattering medium that ...
A radiosity-based method to avoid calibration for Indoor Positioning Systems
(Elsevier, 2018-09-01)
Due to the widespread use of mobile devices, services based on the users current indoor location are growing in significance. Such services are developed in the Machine Learning and Experst Systems realm, and ranges from ...
Direct lightweight temporal compression for wearable sensor data
(IEEE, 2021-02-01)
Emerging technologies enable massive deployment of wireless sensor networks across many industries. Internet of Things (IoT) devices are often deployed in critical infrastructure or health monitoring and require fast ...
Low-cost single-pixel 3D imaging by using an LED array
(Optical Society of America, 2018)
We propose a method to perform color imaging with a single photodiode by using
light structured illumination generated with a low-cost color LED array. The LED array is
used to generate a sequence of color Hadamard ...
The Cost of Change in Parametric Modeling: A Roadmap
(CAD Solutions, 2021)
In this paper, we lay the foundation for estimating the cost associated to
parametric modeling changes and discuss its implications on the broader context of
engineering change management. We provide an analysis of the ...
Inactivation of SARS-CoV-2 by a chitosan/α-Ag2WO4 composite generated by femtosecond laser irradiation
(Nature Research, 2022)
In the current COVID‑19 pandemic, the next generation of innovative materials with enhanced anti‑
SARS‑CoV‑2 activity is urgently needed to prevent the spread of this virus within the community.
Herein, we report the ...
Improved perception of ceramic molds through augmented reality
(Springer Nature, 2022-05-23)
Augmented Reality techniques allow the user to visualize part of the real world through a display device by incorporating graphical information into the existing physical information. In this sense, it is important to know ...
Proof-of-Concept Studies Directed toward the Formation of Metallic Ag Nanostructures from Ag3PO4 Induced by Electron Beam and Femtosecond Laser
(Wiley, 2019)
In this work, for the first time, the instantaneous nucleation and growth processes of Ag nanoparticles on Ag3PO4 mediated by femtosecond laser pulses are reported and analyzed. The investigated samples are pure Ag3PO4sample, ...
Online reconstruction-free single-pixel image classification
(Elsevier, 2019-04)
In single-pixel imaging, a series of illumination patterns are projected onto an object and the reflected or transmitted light from the object is integrated by a photodetector (the single-pixel detector). Then, from the ...
Towards social paradigms for mobile context-aware computing in smart cities
(AISTI (Associaçao Ibérica de Sistemas e Tecnologias de Informaçao), 2016)
Mobile context-aware computing is an essential
component of the smart cities infrastructure. Attempts
were made to develop a model that can effectively
represent a system in device to support context-aware
behavior. ...
