Real-time SOSM super-twisting combined with block control for regulating induction motor velocity
(Institute of Electrical and Electronics Engineers Inc., 2018-06-20)
On this paper, a robust velocity controller applied to a three-phase squirrel-cage induction motor under variable load conditions is designed. The induction motor drives an induction generator representing the load which ...
Heat removal factor in flat plate solar collectors: indoor test method
(MDPI AG, 2018)
This paper presents a couple of methods to evaluate the heat removal factor FR of flat plate solar collectors, as well as a parametric study of the FR against the tilt angle β, and (Ti - Ta)/G, and its effects on the ...
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 ...
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 ...
Application of VM to improve service in a University Cafeteria by adding value to its Serving cardboard box
(SAVE International, 2018)
Optimum design of a nonlinear vibration absorber coupled to a resonant oscillator : a case study
(Hindawi Limited, 2018-04)
This paper presents the optimal design of a passive autoparametric cantilever beam vibration absorber for a linear mass-spring-damper system subject to harmonic external force. The design of the autoparametric vibration ...
Optimization of PPF control of a building-like structure for vibration control
(Instituto Politécnico Nacional, 2018)
This work presents a research on intelligent civil structures, like bridges and buildings, which consists in the use of sensors and actuators to monitor and control some specific parameters of the structures. A recent ...
Biomass and biochar potential, a chance for semidesertic areas like Aguascalientes, Mexico
(IMEKO-International Measurement Federation Secretariat, 2018-04-26)
Biochar obtained from thermochemical conversion of biomass reduces greenhouse gas emissions, improves the physicochemical and microbial properties of soil and absorbs pernicious substances. In addition, applying biochar ...
