Input-output decoupling of Hamiltonian systems: The linear case [PDF]

open access: yes, 1985
In this note we give necessary and sufficient conditions for a linear Hamiltonian system to be input-output decouplable by Hamiltonian feedback, i.e. feedback that preserves the Hamiltonian structure.

Distribution of energy in propagation for ocean extreme wave generation in hydrodynamics laboratory [PDF]

open access: yesGlobal Journal of Environmental Science and Management, 2021
BACKGROUND AND OBJECTIVES: The hydrodynamic uncertainty of the ocean is the reason for testing marine structures as an initial consideration. This uncertainty has an impact on the natural structure of the topography as well as marine habitats.

Entropy-energy inequalities for qudit states [PDF]

open access: yes, 2004
We establish a procedure to find the extremal density matrices for any finite Hamiltonian of a qudit system. These extremal density matrices provide an approximate description of the energy spectra of the Hamiltonian.

An Energy Consistent Discretization of the Nonhydrostatic Equations in Primitive Variables

open access: yesJournal of Advances in Modeling Earth Systems, 2020
We derive a formulation of the nonhydrostatic equations in spherical geometry with a Lorenz staggered vertical discretization. The combination conserves a discrete energy in exact time integration when coupled with a mimetic horizontal discretization ...

Torus–Connected Cycles: A Simple and Scalable Topology for Interconnection Networks

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2015
Supercomputers are today made up of hundreds of thousands of nodes. The interconnection network is responsible for connecting all these nodes to each other.

Non-Hermitian Dirac Hamiltonian in three dimensional gravity and pseudo-supersymmetry [PDF]

open access: yes, 2015
The Dirac Hamiltonian in the (2+1) dimensional curved space-time has been studied with a metric for an expanding de Sitter space-time which is a two sphere.

On k-Path Pancyclic Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2015
For integers k and n with 2 ≤ k ≤ n − 1, a graph G of order n is k-path pancyclic if every path P of order k in G lies on a cycle of every length from k + 1 to n. Thus a 2-path pancyclic graph is edge-pancyclic.

Some properties of the generalized sierpiński gasket graphs [PDF]

open access: yesTransactions on Combinatorics
The generalized Sierpiński gasket graphs $S[G,t]$ are introduced as the graphs obtained from the Sierpiński graphs $S(G,t)$ by contracting single edges between copies of previous phases.

Hamiltonian description of a self-consistent interaction between charged particles and electromagnetic waves [PDF]

open access: yes, 2008
The Hamiltonian description of the self-consistent interaction between an electromagnetic plane-wave and a co-propagating beam of charged particles is considered.
