α-bandlimited diffuser in fractional Fourier optics
(SPIE, 2016)
We propose a method for calculating appropriate α-band limited diffusers using the fractional Fourier transform. In order to do this, we implement a method for performing a numerical interpolation in the fractional Fourier ...
Sustainable boat transportation throughout electrification of propulsion systems: Challenges and opportunities
(Institute of Electrical and Electronics Engineers Inc., 2019)
Global use of carbon-based fuels increased by 1.6 % in 2017 and continued increasing in 2018, after managing to maintain emissions flat between 2014-2017. This trend deviates from the emissions trajectory required to fulfill ...
Diffuser in Fractional Fourier Optics
(OSA - The Optical Society, 2016)
We propose a method for calculating a bandlimited diffuser with smooth spectrum in the Fresnel domain without any 2p phase ambiguities using the fractional Fourier transform. Such diffusers are necessary to avoid problems ...
A wearable system for biosignal monitoring in weightlifting
(Springer London, 2017)
The use of technological aids in sports has increased in the last years. These tools allow to register the athletes’ movements to evaluate and track their performance over time. With that information, it is possible to ...
Robust adaptive control of a planar 3RRR parallel robot for trajectory-tracking applied to crouch gait cycle in children with cerebral palsy
(Institute of Electrical and Electronics Engineers Inc., 2019)
This paper presents the modelling, control and simulation of a 3RRR planar parallel robot, using a robust adaptive control strategy. The objective of this work is to achieve the control over desired trajectory-tracking of ...
A Methodology for Driving Behavior Recognition in Simulated Scenarios Using Biosignals
(Springer, 2019)
The recognition of aggressive driving patterns could aid to improve driving safety and potentially reduce traffic fatalities on the roads. Driving behavior is strongly shaped by emotions and can be divided into two main ...
Design of an electronic system for monitoring muscle activity in weight-lifting
(Institute of Electrical and Electronics Engineers Inc., 2014)
Electronic systems based on body area networks can be used to monitor sports performance. These systems use sensors to acquire signals from the athlete while performing the exercises, and a communication system to transmit ...
Collaborative Model on the Agro-Industrial Supply Chain of Cocoa
(Taylor and Francis Inc., 2017)
Due to globalization and extreme competition in today’s economy, knowledge management that is a systematic management of industries’ knowledge assets for creating value and strategies of the organization plays an important ...
Vehicular road influence areas
(Elsevier Ltd, 2017)
Vehicle operation over paved and unpaved roads is an emission source that significantly contributes to air pollution. Emissions are derived from vehicle exhaust pipes and re-suspension of particulate matter generated by ...
A Sequential Quadratic Programming Model for the Economic-Environmental Dispatch in MT-HVDC
(Institute of Electrical and Electronics Engineers Inc., 2019)
This paper addresses the economic-environmental dispatch problem for thermal plants on a Multi-terminal HVDC power grid. A multi-objective optimization approach is used for modeling the compromise between fuel costs and ...
