Improved subglottal pressure estimation from neck-surface vibration in healthy speakers producing non-modal phonation
(IEE-Institute of Electrical and Electronics Engineers, 2020)
Subglottal air pressure plays a major role in voice production and is a primary factor in controlling voice onset, offset, sound pressure level, glottal airflow, vocal fold collision pressures, and variations in fundamental ...
Seismic behavior of chilean bridges with seismic protection devices
(Escuela de Construcción Civil, Pontificia Universidad Católica de Chile, 2015)
Several bridges with seismic protection systems have been built in the last decade in Chile. Accelerometer networks have been installed in some of them. Seismic records have been obtained by these instruments for moderate ...
In preschool children, physical activity during school time can significantly increase by intensifying locomotor activities during physical education classes
(BioMed Central, 2018)
Objectives: After categorizing preschool children into “active and low active” according to their moderate and vigor‑
ous physical activity (MVPA) in PE classes (PE), we compared these two groups within each sex and by ...
Design and simulation of an accelerometer with improved sensitivity response
(Universidad del ValleColombia, 2016-07-08)
(Eng) The capacitive accelerometers based on microelectromechanical systems (MEMS), are widely used in the automotive
industry, in seismic detection, and in military applications. The sensitivity is one of their main ...
A time to exhaustion model during prolonged running based on wearable accelerometers
(Taylor and Francis Ltd.Reino Unido, 2019)
Defining relationships between running mechanisms and fatigue can be a major asset for optimising training. This article proposes a biomechanical model of time to exhaustion according to indicators derived from accelerometry ...
Visualizing Gait Patterns of Able bodied Individuals and Transtibial Amputees with the Use of Accelerometry in Smart Phones
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Estadística, 2014-07-01)
Human gait analysis is used to indirectly monitor the rehabilitation of patients affected by diseases or to directly monitor patients under orthotic care. Visualization of gait patterns on the instrument are used to ...
Performance of bridges with seismic isolation bearings during the Maule earthquake, Chile
(Elsevier, 2013)
On February 27, 2010 an earthquake of magnitude Mw=8.8, with epicenter in Cobquecura, Maule region, hit the central part of Chile. After the earthquake, a tsunami occurred that caused heavy casualties and damage to buildings ...
Detection and localization of potholes in roadways using smartphones
(Universidad Nacional de Colombia (Sede Medellín). Facultad de Minas., 2016-01-01)
A system for the detection and localization of roadway potholes is proposed and is aimed at collecting data on the roadway potholes using the accelerometer, GPS and compass that are embedded into smartphones using the ...
Diseño de un microsistema para la medición de presión plantar y aceleración de la pierna utilizando PSoC
(Revista Colombiana de Física, 2011)
En este trabajo se presenta el diseño e implementación de un sistema de plantillas para el registro de presiones plantares y aceleración triaxial de la pierna, durante la marcha. En el primer caso, se utilizan cuatro ...
Improvement of low frequency identification for wind turbines employing eemd and time integration.
(Universidad Nacional de Colombia Sede Manizales, 2014-12-20)
Nowadays wind turbines are wide employed as a clean energy resource. However, their use implies a wide number of eolic structures which also requires a demanding monitoring and maintenance. The most technique employed for ...
