Selecting a suitable battery technology for the photovoltaic battery integrated module
(2019-10-31)
The use of batteries is indispensable in stand-alone photovoltaic (PV) systems, and the physical integration of a battery pack and a PV panel in one device enables this concept while easing the installation and system ...
Quantifying the benefits of a solar home system-based DC microgrid for rural electrification
(2019)
Off-grid solar home systems (SHSs) currently constitute a major source of providing basic electricity needs in un(der)-electrified regions of the world, with around 73 million households having benefited from off-grid solar ...
Robustness of LSTM neural networks for the enhancement of spectral parameters in noisy speech signals
(2019)
In this paper, we carry out a comparative performance analysis of Long Short-term Memory (LSTM) Neural Networks for the task of noise reduction. Recent work in this area has shown the advantages of this kind of network for ...

(2022-04)
Este trabajo presenta el análisis y deducción de las condiciones que garantizan la estabilidad de un sistema de primer orden implementando un controlador PD en conexión con una no linealidad sectorial general usando el ...
A comparison of bio-inspired optimization methodologies applied to the tuning of industrial controllers
(2016-11-09)
A comparison of different bio-inspired methods is presented for the problem of tuning the
parameters of a PID industrial controller for second order plus time delay plants. The compared algorithms are representative of ...
Exploring the boundaries of Solar Home Systems (SHS) for off-grid electrification: Optimal SHS sizing for the multi-tier framework for household electricity access
(2019-04-15)
With almost 1.1 billion people lacking access to electricity, solar-based off-grid products like Solar Home Systems (SHS) have become a promising solution to provide basic electricity needs in un(der)-electrified regions. ...
Smart placement of a two-arm assembly for an everyday object manipulation humanoid robot based on capability maps
(2018)
A robot that will execute everyday object manip-
ulation tasks needs a competent body that can handle as many
different objects as possible in as many ways as possible. To
accomplish this, we must design the robot body ...
Hidden Markov Models for artificial voice production and accent modification
(2016)
In this paper, we consider the problem of accent modification between Castilian Spanish and Mexican Spanish. This is an interesting application area for tasks such as the automatic dubbing of pictures and videos with ...
