Stabilization of causally and non-causally coupled map lattices [PDF]

, 2004
Two-dimensional coupled map lattices have global stability properties that depend on the coupling between individual maps and their neighborhood. The action of the neighborhood on individual maps can be implemented in terms of "causal" coupling (to ...

Power coupling

, 2011
Power coupling is the subject of a huge amount of literature and material since for each particular RF structure it is necessary to design a coupler that satisfies some requirements, and several approaches are in principle possible.

Analysis of Aerodynamic Noise Characteristics of High-Speed Train Pantograph with Different Installation Bases

Applied Sciences, 2019
The high-speed-train pantograph is a complex structure that consists of different rod-shaped and rectangular surfaces. Flow phenomena around the pantograph are complicated and can cause a large proportion of aerodynamic noise, which is one of the main ...

Dynamical spin-spin coupling of quantum dots

, 2013
We carried out a nested Schrieffer-Wolff transformation of an Anderson two-impurity Hamiltonian to study the spin-spin coupling between two dynamical quantum dots under the influence of rotating transverse magnetic field.

Comment on the frozen QCD coupling

, 2013
The frozen QCD coupling is a parameter often used as an effective fixed coupling. It is supposed to mimic both the running coupling effects and the lack of knowledge of alpha_s in the infrared region.

Coupling Poisson and Jacobi structures on foliated manifolds

, 2004
Let M be a differentiable manifold endowed with a foliation F. A Poisson structure P on M is F-coupling if the image of the annihilator of TF by the sharp-morphism defined by P is a normal bundle of the foliation F.

Mode coupling in solar spicule oscillations

, 2015
In a real medium which has oscillations, the perturbations can cause the energy transfer between different modes. The perturbation interpreted as an interaction between the modes is inferred as mode coupling.

Analysis of the Transonic Buffet Characteristics of Stationary and Pitching OAT15A Airfoil

Applied Sciences
Transonic buffet flow is a classical complex and unstable flow that has a negative effect on aircraft fly safety. Therefore, it is crucial to study the unsteady characteristics of buffet flow. The numerical analysis method is very useful in achieving the

Surrogate Based Optimization of Aerodynamic Noise for Streamlined Shape of High Speed Trains

Applied Sciences, 2017
Aerodynamic noise increases with the sixth power of the running speed. As the speed increases, aerodynamic noise becomes predominant and begins to be the main noise source at a certain high speed.
