Modelo teórico para cuantificar la eficiencia térmica del calentador eléctrico en una secadora doméstica de ropa
(Universidad de Cuenca, 2015-09)
In this research paper, enhancement of generation and transfer heat on a tumbler dryer electric
heater is achieved by a developed theoretical model, through the thermal efficiency estimation on the
electric heater. Air ...
Modeling upper eyelid kinematics during spontaneous and reflex blinks
(Elsevier B.V., 2010-08-15)
To test a mathematical model for measuring blinking kinematics.Spontaneous and reflex blinks of 23 healthy subjects were recorded with two different temporal resolutions. A magnetic search coil was used to record 77 blinks ...
Skyrmion pinball and directed motion on obstacle arrays
(2020-01-01)
We examine skyrmions interacting with a square array of obstacles under ac drives applied in one or two directions. For a single direction of ac driving, we find that the Magnus force in conjunction with the obstacle ...
Front depinning by deterministic and stochastic fluctuations: A comparison
(American Physical Society, 2019)
Driven dissipative many-body systems are described by differential equations for macroscopic variables which include fluctuations that account for ignored microscopic variables. Here, we investigate the effect of deterministic ...
Active colloidal chains with cilia- and flagella-like motion
(Iop publishing LTD, 2018-05)
It has been shown that self-assembled chains of active colloidal particles can present sustained oscillations. These oscillations are possible because the effective diffusiophoretic forces that mediate the interactions of ...
Shapiro steps and nonlinear skyrmion Hall angles for dc and ac driven skyrmions on a two-dimensional periodic substrate
(2020-09-10)
For an overdamped particle moving over a two-dimensional periodic substrate under combined dc and ac drives, a series of steps can appear in the velocity force curves that are known as Shapiro steps. Here we show that for ...
Stochastic dynamics of collective modes for Brownian dipoles
(American Physical Society, 2015-03)
The individual motion of a colloidal particle is described by an overdamped Langevin equation. When rotational degrees of freedom are relevant, these are described by a corresponding Langevin process. Our purpose is to ...
Multiaxial cyclic plasticity in accordance with 1D hyperbolic models and Masing criteria
(John Wiley and Sons LtdUniversidad EAFIT. Departamento de Ingeniería Mecánica, 2018-12-10)
Bounding surface plasticity models based on one-dimensional hardening functions are broadly accepted as a valid approach to represent the multiaxial cyclic behavior of undrained cohesive soils. However, under certain ...
Fractional order model identification: Computational optimization
(2015-10-26)
This paper deals with the identification of fractional models with one fractional parameter. This kind of models are capable to represent an extensive range of dynamics, including overdamped and oscillatory behaviors. The ...
Robustness/performance tradeoff for anisochronic plants with two degrees of freedom PID controllers
(2015)
In this paper, the anisochronic model (which is able to represent both over-damped and under-damped process with the same topology) is used for the tuning of PI and PID controllers. The relationship between robustness and ...
