Auto-Associative Initialization of LSTM Neural Networks for Fundamental Frequency Detection in Noisy Speech Signals
(2018)
In this paper, we present a new approach for fundamental frequency detection in noisy speech, based on Long Short-term Memory Neural Networks (LSTM). Fundamental frequency is one of the most important parameters of human ...
Robotic architecture design to map an action language to a low level motion commands for skillful manipulation
Diseño de una arquitectura robótica para mapear un lenguaje de acción a comandos de movimiento de bajo nivel para manipulación hábil
(2019)
This paper gives an overview of a robotic architecture meant for skillful manipulation. This
design is meant to close the gap between the high level layer (reasoning and planing layer) and the
object model system (physical ...

(2020-09-28)
En Latinoamérica el temor al delito es una preocupación constante, la cual se ha incorporado no solo en la retórica populista política sino también en la forma como se construyen las ciudades. En Costa Rica como en otras ...
Bases y perspectivas de la potencial regulación para la gestión integral de residuos de construcción en Costa Rica
(2022)
Construction and demolition waste constitutes an important part of the total solid waste generated worldwide. Costa Rica must improve the level of management of this type of waste, because although there is a general level ...
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 ...
Dynamic Analysis of Modified Structural Systems
(1987-05-20)
The subject of this study is the development of a set of methods for the calculation of the changes in the frequency of vibration and mode shape of a structure due to changes in the physical system. Such changes may consist ...
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 ...
