Elastic wave propagation in confined granular systems [PDF]
, 2005 We present numerical simulations of acoustic wave propagation in confined granular systems consisting of particles interacting with the three-dimensional Hertz-Mindlin force law.

On the design of an optimal coherent multistatic radar network configuration
IET Radar, Sonar & Navigation, 2022 The purpose of operating a radar system multistatically is to acquire information about targets of interest more quickly and reliably than would be possible using disparate radars, which fuse data and track post‐detection.

Quantum Coherences of Maximally Coherent Mixed State
Journal of Harbin University of Science and Technology, 2022 Quantum coherence， as an important physical resource， is one of the most basic characteristics of quantum mechanics， and it is also the advantage of quantum information， which attracts the interest and attention of a large number of scientific ...

Coherent-Classical Estimation for Linear Quantum Systems
, 2017 We study a coherent-classical estimation scheme for a class of linear quantum systems, where the estimator is a mixed quantum-classical system that may or may not involve coherent feedback.

Low-dimensional dynamical system model for observed coherent structures in ocean satellite data [PDF]
, 2000 The dynamics of coherent structures present in real-world environmental data is analyzed. The method developed in this Paper combines the power of the Proper Orthogonal Decomposition (POD) technique to identify these coherent structures in experimental ...

Dynamical regimes of dissipative quantum systems
, 2013 We reveal several distinct regimes of the relaxation dynamics of a small quantum system coupled to an environment within the plane of the dissipation strength and the reservoir temperature.

Data-derived iterative channel estimation with channel tracking for a mobile fourth generation wide area OFDM system [PDF]
, 2003 In this paper an iterative channel estimation technique for a mobile fourth generation coherent orthogonal frequency division multiplexing (OFDM) system is proposed. Coherent detection dictates that a per-subband estimate of the frequency response of the

Applicable Algebra in Engineering, Communication and ComputingWe describe the notion of stability of coherent systems as a framework to deal with redundancy. We define stable coherent systems and show how this notion can help the design of reliable systems. We demonstrate that the reliability of stable systems can be efficiently computed using the algebraic versions of improved inclusion-exclusion formulas and ...

Dynamic stress–strength reliability estimation of system with survival signature
Statistical Theory and Related Fields, 2018 In this paper, we proposed a dynamic stress–strength model for coherent system. It is supposed that the system consists of n components with initial random strength and each component is subjected to random stresses.
