Scaling predictions for radii of weakly bound triatomic molecules
The mean-square radii of the triatomic molecules 4He 3, 4He 2- 6Li, 4He 2- 7Li, and 4He 2- 23Na were calculated using a renormalized three-body model with a pairwise Dirac-δ interaction, having as physical inputs only the ...
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 ...
Effect of tillage on fractal indices describing soil surface microrelief of a Brazilian Alfisol
(Elsevier B.V., 2006-10-01)
Soil surface roughness is known to influence water infiltration, runoff and erosion. Soil surface roughness changes with management and weather and its mathematical description still remains an important issue. The main ...
Influence of type 1 diabetes on the symbolic analysis and complexity of heart rate variability in young adultsInfluência do diabetes tipo 1 na análise simbólica e complexidade da variabilidade da frequência cardíaca em jovens adultos
Background: Type 1 diabetes mellitus can cause autonomic changes, which can be assessed by heart rate variability. Among the heart rate variability assessment methods, the symbolic analysis and Shannon entropy, based on ...
