From the Air to the Ground: An Experimental Approach to Assess LiPo Batteries for a Second Life
(2022-05)
Many are the applications that use energy stored in lithium-ion (Li-ion) batteries to power themselves. Without a doubt this type of energy storage device has changed the way of living. However, a major concern regarding ...
Toward Thermochromic VO2 Nanoparticles Polymer Films Based Smart Windows Designed for Tropical Climates
(2022-10-10)
Thermochromic smart windows have been extensively investigated due to two main benefits: first, the comfort for people in a room through avoiding high temperatures resulting from solar heating while taking advantage of the ...
Physical Integration of PV-Battery System: Advantages, Challenges, and Thermal Model
(2016-04-04)
We present a novel approach to physically integrate a PV module, dc/dc converter, dc/ac microinverter and a battery pack. The main advantages and challenges to realize this integration are presented. Since the thermal ...
New predictive PID controllers for packet dropouts in wireless networked control systems
(2017-11)
Four new predictive control algorithms are presented to compensate dropouts in wireless networked control systems. The control strategies are based on Model based predictive control (MBPC) with PID control structure. The ...
Evaluation of denoising algorithms for footsteps sound classification in noisy environments
(2021)
Identifying a person using footsteps sounds is part
of the recent research in developing biometrics, systems designed
to identify an individual in a group using body measurements.
The sound of footsteps has a short ...
Producción artificial de habla: Síntesis de voz
(2015)
A finales de la década de los 80, el estadounidense Raymond Kurzweil, inventor del primer sistema comercial que es capaz de tomar texto de un libro y pronunciarlo mediante habla artificial, escribió la obra “La era de las ...
A modeling methodology to evaluate the impact of temperature on Solar Home Systems for rural electrification
(2018)
Solar Home Systems (SHS) have recently gained prominence as the most promising solution for increasing energy access in remote, off-grid communities. However, the higher than standard testing conditions (STC) temperatures ...
An Experimental Study on Speech Enhancement Based on a Combination of Wavelets and Deep Learning
(2022-06-20)
The purpose of speech enhancement is to improve the quality of speech signals degraded by noise, reverberation, or other artifacts that can affect the intelligibility, automatic recognition, or other attributes involved ...
Experimental study on transfer learning in denoising autoencoders for speech enhancement
(2020)
The quality of speech signals is affected by a combination of background noise, reverberation, and other distortions in real-life environments. The processing of such signals presents important challenges for tasks such ...
