Rotationally symmetric solutions to the Cahn-Hilliard equation
(Southwest Missouri State University, 2017)
This paper is devoted to construction of new solutions to the Cahn-Hilliard equation in ℝd. Staring from the Delaunay unduloid Dô with parameter τ ∈ (0, τ∗) we find for each sufficiently small ε a solution u of this equation ...
Robust mixed order backstepping control of non-linear systems
(Institution of Engineering and Technology, 2018-06-12)
Robust backstepping control of non-linear systems with derivation orders (commensurate or non-commensurate) lying at interval (0, 2) is proposed in this study. The stability and robustness properties are proved using a ...
On the instability of nonlinear functional differential equations of fifth order
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Matemáticas, 2017-07-01)
The author gives sufficient conditions for non-existence of periodic solutions of two higher order nonlinear delay differential systems. Our technical approach is based on the construction of two suitable Lyapunov type ...
Design of fuzzy robust control strategies for a distributed solar collector field
(Elsevier Ltd, 2018)
This paper presents novel control strategies using Takagi–Sugeno fuzzy models combined with a parametric uncertainty robust control approach to address both the nonlinearities of a process and the disturbances that act on ...
Concentrating standing waves for the fractional nonlinear Schrodinger equation
(Elsevier, 2014-01-15)
We consider the semilinear equation
epsilon(2s)(-Delta)(s)u + V(x)u - u(p) = 0, u > 0, u is an element of H-2s(R-N)
where 0 < s < 1, 1 < p < N+2s/N-2s, V (x) is a sufficiently smooth potential with inf(R) V(x) > ...
Heart rate variability dynamics for the prognosis of cardiovascular risk
(Public Library of Science, 2011-02)
Statistical, spectral, multi-resolution and non-linear methods were applied to heart rate variability (HRV) series linked with classification schemes for the prognosis of cardiovascular risk. A total of 90 HRV records were ...
A saliency-based bottom-up visual attention model for dynamicscenes analysis
(Springer, 2013)
This work proposes a model of visual bottom-up attention for dynamic scene analysis. Our work addsmotion saliency calculations to a neural network model withrealistic temporal dynamics [(e.g., building motion salienceon ...
