Vehicular road influence areas
(Elsevier Ltd, 2017)Vehicle operation over paved and unpaved roads is an emission source that significantly contributes to air pollution. Emissions are derived from vehicle exhaust pipes and re-suspension of particulate matter generated by ... -
Bibliometric analysis in motorcycle accident research: a global overview
(Springer Netherlands, 2019)770 million motorcycles are estimated on the roads. Motorcyclists represent more than 380,000 annual deaths worldwide. 28% of the global fatalities in the roads in 2016. With the increase of the accident rate, studies have ... -
Design and implementation of an energy monitoring system for buildings based on internet of things architecture
(Springer Verlag, 2017)Monitoring environmental variables in buildings is a first step to implement and provide services related to energy savings, comfort and safety among others issues. In this work we design and implement an Energy Monitoring ... -
The craft brewing industry in latin America: The case of Colombia
(Palgrave Macmillan, 2017)This chapter presents a brief description of the beer industry in Latin America and specifically in Colombia. The main focus is on the performance of the craft brewing industry. It was found that the same patterns followed ... -
Vehicle speed estimation using audio features and neural networks
(Institute of Electrical and Electronics Engineers Inc., 2017)Many car accidents that result in pedestrian deaths or serious injuries are due to their inattention when crossing the street. Pedestrians often get distracted using mobile phones or music players, what prevents them to ... -
A wearable system for biosignal monitoring in weightlifting
(Springer London, 2017)The use of technological aids in sports has increased in the last years. These tools allow to register the athletes’ movements to evaluate and track their performance over time. With that information, it is possible to ... -
Design and control of an unmanned surface vehicle for environmental monitoring applications
(Institute of Electrical and Electronics Engineers Inc., 2017)Unmanned Surface Vehicles (USV) have been used in a wide range of applications, in particular in environmental monitoring. In this work we propose the design and control of an USV which is intended to be used for monitoring ... -
Rethinking professional autonomy: Autonomy to develop and to publish news in Mexico and Colombia
(SAGE Publications Ltd, 2017)Professional autonomy has usually been defined in terms of journalists' perceptions of their control over their work vis-à-vis organizational supervisors. Using surveys of journalists in Colombia and Mexico, we identify ... -
Expanding Influences Research to Insecure Democracies: How violence, public insecurity, economic inequality and uneven democratic performance shape journalists’ perceived work environments
(Routledge, 2017)Democracies with sharp violence and public insecurity have proliferated in recent decades, with many also featuring extreme economic inequality. These conditions have not been explicitly considered in comparative research ... -
On classical thermal stability of black holes with a dynamical extrinsic curvature
(Academic Press Inc., 2017)We study the deformation caused by the influence of the extrinsic curvature on a vacuum spherically symmetric metric embedded in a five-dimensional bulk. We investigate the resulting black-holes obtaining general characteristics ... -
Effectiveness of a visual noise warning system on noise levels in a surgical ICU: A quality improvement programme
(Lippincott Williams and Wilkins, 2019)BACKGROUNDThe effects of noise are harmful to patients in the ICU environment, and the latter are particularly noisy places. High noise levels seem to be a factor in sleep disturbance, which can, in turn, result in increased ... -
