Quasi-Projective Synchronization of Distributed-Order Recurrent Neural Networks

open access: yesFractal and Fractional, 2021
In this paper, the quasi-projective synchronization of distributed-order recurrent neural networks is investigated. Firstly, based on the definition of the distributed-order derivative and metric space theory, two distributed-order differential ...

Time-fractional Diffusion of Distributed Order [PDF]

open access: yesJournal of Vibration and Control, 2008
The partial differential equation of Gaussian diffusion is generalized by using the time-fractional derivative of distributed order between 0 and 1, in both the Riemann-Liouville and the Caputo sense. For a general distribution of time orders we provide the fundamental solution, which is a probability density, in terms of an integral of Laplace type ...

DISTRIBUTED ORDER FRACTIONAL SUB-DIFFUSION [PDF]

open access: yesFractals, 2004
A distributed order fractional diffusion equation is considered. Distributed order derivatives are fractional derivatives that have been integrated over the order of the derivative within a given range. In this paper, sub-diffusive cases are considered. That is, the order of the time derivative ranges from zero to one.

Partial Up-Up-Down Order with the Continuously Distributed Order Parameter in the Triangular Antiferromagnet TmMgGaO_{4}

open access: yesPhysical Review X, 2020
We show that frustrated quasidoublets without time-reversal symmetry can host highly unconventional magnetic structures with continuously distributed order parameters even in a single-phase crystal.

Distributed-order time-fractional wave equations

open access: yesZeitschrift für angewandte Mathematik und Physik, 2022
Distributed-order time-fractional wave equations appear in the modeling of wave propagation in viscoelastic media. The material characteristics of the medium are modeled through constitutive functions or distributions in the distributed-order constitutive law.

Distributed Consensus Algorithms in Sensor Networks with Higher-Order Topology

open access: yesEntropy, 2023
Information aggregation in distributed sensor networks has received significant attention from researchers in various disciplines. Distributed consensus algorithms are broadly developed to accelerate the convergence to consensus under different ...

Observer Design for Second-Order Distributed Parameter Systems in R2 [PDF]

open access: yesModeling, Identification and Control, 2008
Observer design for second-order distributed parameter systems in R2 is addressed. Particularly, second order distributed parameter systems without distributed damping are studied.

Delta Plots and Coherent Distribution Ordering

open access: yesThe American Statistician, 2008
Social scientists often compare subclasses of populations or manipulatons. For example, in comparing task-completion times across two levels of a manipulations, if one group has faster overall mean response, it is natural to ask if the fastest 10% of the first group has a faster mean than the fastest 10% of the second group, and so on.
