Energy harvesting from the vibrations of a passing train: Effect of speed variability
(2016-10-03)
This paper builds on a previous study which investigated the amount of energy that could be harvested from the vibration induced by a passing train using a trackside energy harvester. In that study, the optimum parameters ...
Measurement of flame speed in copper concentrate clouds
(SOC CHILENA QUIMICA, 2006)
More than 50% of the world primary copper is produced by Flash Smelting technology [1], which partially burns copper concentrate particles. It has proved to be superior to other processes because of its low fuel consumption, ...
Does China’s high-speed rail development lead to regional disparities? A network perspective
This research examines whether cities are getting more equally accessible and connected via
high-speed rail (HSR) in China over the period from 2010 to 2015. Existing studies mainly use
network centralities to describe ...
High-Speed audio communications in domestic power line channels
(Institute of Electrical and Electronics Engineers Inc., 2017)
A low-cost transceiver for short-range PLC audio communications is designed and developed. This design relies on the measured noise and interference of PLC domestic channels over a long period of time. Several design choices ...
The Change Processes in Selective Attention during Adulthood. Inhibition or Processing Speed?
(Cambridge University Press, 2020-10)
Selective attention is involved in multiple daily activities. Several authors state that it experiences a decline after 20 years, although there is no agreement regarding the cognitive processes that explain it. Two theories ...
Estimating vocal fold contact pressure from raw laryngeal high-speed videoendoscopy using a Hertz contact model
(MDPI AG, 2019)
The development of trauma-induced lesions of the vocal folds (VFs) has been linked to a high collision pressure on the VF surface. However, there are no direct methods for the clinical assessment of VF collision, thus ...
Speed of light demonstration using Doppler beat
(IOP Publishing, 2018-04)
From an apparatus previously designed for measuring the Doppler shift using a rotating mirror, an improved, versatile version was developed for speed of light demonstrations in a classroom or a teaching laboratory. By ...
Gait speed correlates in a multiracial population of community-dwelling older adults living in Brazil: a cross-sectional population-based study
(Biomed Central LtdLondonInglaterra, 2013)
