A Decade of GRB Follow-Up by BOOTES in Spain (2003–2013)

2016

This article covers ten years of GRB follow-ups by the Spanish BOOTES stations: 71 follow-ups providing 23 detections. Follow-ups by BOOTES-1B from 2005 to 2008 were given in a previous article and are here reviewed and updated, and additional detection data points are included as the former article merely stated their existence. The all-sky cameras CASSANDRA have not yet detected any GRB optical afterglows, but limits are reported where available.

Long-term socio-economic impact of COVID-19 on sport sector

2021

The nature of the Covid-19 pandemic’s induced economic crisis is unprecedented: beyond the repeated health and economic shocks, the long-term effects on human capital, productivity and behaviour may also be long-lasting. One of the sectors hit particularly severe by the impacts of Covid-19 is sport. The very existence and work of sport organisations, clubs, professional sport leagues, fitness centres, athletes, coaches, sport staff, sport volunteers and sport-related business, including sport event organisers and sport media, have been battling with staying afloat by cutting all unnecessary expenses and consolidating costs while also trying to maintain the community feel of bringing people …

Modeling and Backstepping Control of the Electronic Throttle System

2013

Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher at: http://dx.doi.org/10.1155/2013/871674 Open access Electronic throttle is widely used in modern automotive engines. An electronic throttle system regulates the throttle plate angle by using a DC servo motor to adjust the inlet airflow rate of an internal combustion engine. Its application leads to improvements in vehicle drivability, fuel economy, and emissions. In this paper, by taking into account the dynamical behavior of the electronic throttle, the mechanism model is first built, and then the mechanism model is transformed into the state-space model. Based on the s…
