Autonomous curriculum and EFL motivation and learning. The effects of autonomous curriculum approaches on motivation and learning in EFL: a colombian case study at the Universidad de los Andes
(Maestría en EducaciónFacultad de Educación, 2012)
This is a qualitative case study based in an English as a foreign language (EFL) context within a private research university in Bogotá, Colombia. The objective of this study is to examine the impact of autonomous approaches ...
Advances of implicit description techniques in modelling and control of switched systems
(Springer Verlag, 2020-01-01)
Our contribution is devoted to a constructive overview of the implicit system approach in modern control of switched dynamic models. We study a class of non-stationary autonomous switched systems and formally establish the ...
Exploring paradigm shift impacts in urban mobility: Autonomous Vehicles and Smart Cities
(2018)
Urban mobility is a dynamic system that has had a (slow) natural evolution. Scientists and engineers are currently developing new mobility technologies. A progressive paradigm shift will change everything from the fuel ...
Mean Dimension and Metric Mean Dimension for Non-autonomous Dynamical Systems
(Cartagena de Indias, 2020-10-07)
In this paper we extend the definitions of mean dimension and metric mean dimension for non-autonomous dynamical systems. We show some properties of this extension and furthermore some applications to the mean dimension ...
Chronic obstructive pulmonary disease and heart rate variability: A literature update
(2014-10-03)
Background: The literature indicates that chronic obstructive pulmonary disease (COPD) affects cardiac autonomic control. In this study, we conducted a literature review in order to investigate the heart rate variability ...
3D Formation Control of Autonomous Vehicles Based on Null-Space
(Springer, 2016-12)
This paper proposes a new algorithm for controlling a formation of multiple autonomous aerial vehicles based on multiple control objectives. The strategy includes using the null space of a Jacobian matrix to achieve the ...
Is heart rate variability a valuable method to investigate cardiac autonomic dysfunction in subjects with leukemia? A systematic review to evaluate its importance in clinical practice
(2019-01-01)
Impaired cardiovascular and autonomic function during treatment and during recovery from leukemia has been indicated. In this context, heart rate variability (HRV) is a non-invasive measure that describes the oscillations ...
Autonomic control of heart rate during forced activity and digestion in the snake Boa constrictor
(Company of Biologists Ltd, 2001-10-01)
Reptiles, particularly snakes, exhibit large and quantitatively similar increments in metabolic rate during muscular exercise and following a meal, when they are apparently inactive. The cardiovascular responses are similar ...
