I-PD controller as an structural alternative to servo/regulation tradeoff tuning
(2018)One of the recurrent topics in the PI/PID literature of recent years is the incorporation of the tradeoff between the two possible modes of closed-loop operation: servo and regulation. Tuning rules are usually provided as ... -
Identification of Costa Rican speaker’s age group based on acoustic vowel analysis
(2022-04-22)The identification of the speaker’s age is a fundamental task in human-computer interaction. In particular, the recognition of children has drawn attention from the research community due to the vulnerability of se persons ... -
Impacto fiscal de la descarbonización del transporte en Costa Rica y opciones de política para manejarlo
(2021-07)El Plan de Descarbonización de Costa Rica promueve el transporte público como principal opción de movilidad y fomenta la electrificación de la flota vehicular, lo cual habilitará múltiples beneficios socioeconómicos. Sin ... -
Implementación de un controlador DMC para una columna de destilación binaria
(2021-08-31)Las columnas de destilación son ampliamente utilizadas mundialmente; y la industria costarricense no es la excepción. En el país, se destila alcohol a partir de caña de azúcar, lo que resultó vital ante la situación de ... -
Improvement of the Control System Performance based on Fractional-Order PID Controllers and Models with Robustness Considerations
(2018)In this paper we assess the performance improvement achievable by using onedegree-of-freedom fractional-order proportional-integral-derivative controllers (FOPI/FOPID) instead of their integer-order counterparts (PI/PID). ... -
Improving automatic speech recognition containing additive noise using deep denoising autoencoders of lstm networks
(2016)Automatic speech recognition systems (ASR) suffer from performance degradation under noisy conditions. Recent work, using deep neural networks to denoise spectral input features for robust ASR, have proved to be successful. ... -
Improving post-filtering of artificial speech using pre-trained LSTM neural networks
(2019)Several researchers have contemplated deep learning-based post-filters to increase the quality of statistical parametric speech synthesis, which perform a mapping of the synthetic speech to the natural speech, considering ... -
