Usability assessment of a portable corneal topography device
(Springer Verlag, 2019)
This study aimed to identify design and usability issues of a portable corneal topography device, its software and manual. A usability test with a think aloud protocol was carried out by sixteen experienced optometrists. ...
StrokeAggregator : consolidating raw sketches into artist-intended curve drawings
(Association for Computing Machinery, 2018)
When creating line drawings, artists frequently depict intended curves using multiple, tightly clustered, or overdrawn, strokes. Given such sketches, human observers can readily envision these intended, aggregate, curves, ...
Real-time induction motor velocity controller applying SOSM super-twisting combined with state-feedback linearization
(Institute of Electrical and Electronics Engineers Inc., 2018-01)
On this paper, a robust velocity controller based on state-feedback linearization technique combined with super-twisting control law, as a second order sliding mode algorithm, is proposed. This closed-loop scheme is applied ...
Hydrodynamic dispersion in heterogeneous anisotropic porous media : a simple model for anomalous diffusion emergence
(Elsevier B.V., 2018-10)
Anomalous transport processes in porous media have become a central physical issue due to the increasing amount of processes and applications where it appears, ranging from contaminant transport in aquifers and oil recovery ...
Predefined-time robust contour tracking of robotic manipulators
(Elsevier Ltd, 2019)
Robotic tasks are primarily defined to comply to spatial and time constraints, and in several of such tasks, it is required to track a nominal contour depending just on spatial coordinates, without involving the time ...
Virtual vibration absorbers in motion control of a quadrotor aerial vehicle
(International Institute of Acoustics and Vibration, IIAV, 2018)
Passive and active vibration absorbers have been widely used to suppress undesirable frequency harmonic excitations in flexible mechanical structures. This paper introduces a study on the application of virtual active ...
