A Structural Reconstruction Method of Large Ship Based on Grey Theory

open access: yesShanghai Jiaotong Daxue xuebao, 2021
Aimed at the reconstruction problem of foreign large-scale warships, the spacing and minimum plate thickness of some profiles of large-scale warships are obtained by adopting the grey theory method and taking the data in the design code of warships as ...

A Supermartingale Theory-Based Random Compensation Algorithm for Visible Light Communication/Radio Frequency Hybrid Networks

open access: yesIEEE Access, 2023
Visible light communication (VLC)/radio frequency (RF) hybrid networks exhibit large system capacity, high reliability, and low access latency. To simplify the resource allocation process of such hybrid networks, we devise a random compensation algorithm

Large deviations in discrete-time renewal theory [PDF]

open access: yesStochastic Processes and their Applications, 2021
We establish sharp large deviation principles for cumulative rewards associated with a discrete-time renewal model, supposing that each renewal involves a broad-sense reward taking values in a real separable Banach space. The framework we consider is the pinning model of polymers, which amounts to a Gibbs change of measure of a classical renewal ...

Dynamical symmetries and crossovers in a three-spin system with collective dissipation

open access: yesNew Journal of Physics, 2015
We consider the non-equilibrium dynamics of a simple system consisting of interacting spin-1/2 particles subjected to a collective damping. The model is close to situations that can be engineered in hybrid electro/opto-mechanical settings.

Compactness in the theory of large deviations [PDF]

open access: yesStochastic Processes and their Applications, 1995
Large deviation principles are expressed as the vague or narrow convergence of sequences of the set functions called capacities. As an application, a short proof of Gärtner-Ellis criterion for the large deviation principle is given. The capacity methods introduced in the paper are also used in forthcoming papers [\textit{G. L.

Robustness in formation control of mobile robots using leader-follower method

open access: yesAdvances in Mechanical Engineering, 2023
This paper presents the robustness in formation control of multiple mobile robots using leader-follower method. The uncertainty considered is the measured error which is included in the relative state. The robust stability conditions against the relative

Adaptive region tracking control for underwater vehicles with large initial deviation and general uncertainty

open access: yesInternational Journal of Advanced Robotic Systems, 2021
A region tracking control system is developed for underwater vehicles with large initial deviation and general uncertainty. The developed system is a nonlinear cascaded system, consisting of two subsystems in series.

Large Deviations Theory in Exponential Families

open access: yesThe Annals of Mathematical Statistics, 1968
0. Summary. We consider repeated independent sampling from one member of an exponential family of probability distributions. The probability that the sample mean of n such observations falls into some set Sn is, by definition, a "large deviations", "small deviations", or "medium deviations" problem depending on the location of the set S.

Large Deviations Properties of Maximum Entropy Markov Chains from Spike Trains

open access: yesEntropy, 2018
We consider the maximum entropy Markov chain inference approach to characterize the collective statistics of neuronal spike trains, focusing on the statistical properties of the inferred model.

Level 2 and level 2.5 large deviation functionals for systems with and without detailed balance

open access: yesNew Journal of Physics, 2016
Large deviation functions are an essential tool in the statistics of rare events. Often they can be obtained by contraction from a so-called level 2 or level 2.5 large deviation functional characterizing the empirical density and current of the ...
