The ‘bare bones’ (BB) formulation of particle swarm optimisation (PSO) was originally advanced as a model of PSO dynamics. The idea was to model the forces between particles with sampling from a probability distribution in the hope of understanding swarm behaviour with a conceptually simpler particle update rule. ‘Bare bones with jumps’ (BBJ) proposes three significant extensions to the BB algo...
Functional metrics of human muscles: decay with aging Paolo Gava (1), Ugo Carraro (1,2) (1) Laboratory of Translational Myology of the Interdepartmental Research Center of Myology, Department of Biomedical Science, University of Padova, Italy; (2) IRRCS Fondazione Ospedale San Camillo, Venezia, Italy E-mail: [email protected] The decline of the performance of the human muscle with aging is...
In this paper, we focus on modeling and explaining periodic oscillations in gene–protein systems with a simple nonlinear model and on analyzing effects of time delay on the stability of oscillations. Our main model of genetic regulation comprises of a two-gene system with an autoregulatory feedback loop. We exploit multiple time scales and hysteretic properties of the model to construct periodi...
Some invariance principles for additive functionals of simple exclusion with finite-range translation-invariant jump rates p i j = p j − i in dimensions d ≥ 1 are established. A previous investigation concentrated on the case of p symmetric. The principal tools to take care of nonreversibility, when p is asymmetric, are invariance principles for associated random variables and a “local balance”...
Optimal Guaranteed Cost Control of Stochastic Discrete-time Systems under Markovian Regime Switching
A problem of robust guaranteed cost control of stochastic discrete-time systems with parametric uncertainties under Markovian switching is considered. The jump Markovian switching is modelled by a discrete-time Markov chain and the noise or stochastic environmental disturbance is modelled by a sequence of identically independently normally distributed random variables. Using linear matrix inequ...
This contribution shows how unsupervised Markovian segmentation techniques can be accelerated when implemented on graphics hardware equipped with a Graphics Processing Unit (GPU). Our strategy exploits the intrinsic properties of local interactions between sites of a Markov Random Field model with the parallel computation ability of a GPU. This paper explains how classical iterative site-wise-u...
This paper deals with problems of parity space-based fault detection for a class of discrete-time linear Markovian jump systems. A new algorithm is firstly introduced to reduce the computation of mode-dependent redundancy relation parameter matrices. Different from the case of linear time invariant systems, the parity space-based residual generator for a Markovian jump system cannot be designed...
The Fractional Langevin Equation (FLE) describes a non-Markovian Generalized Brownian Motion with long time persistence (superdiffusion), or anti-persistence (subdiffusion) of both velocity-velocity correlations, and position increments. It presents a case of the Generalized Langevin Equation (GLE) with a singular power law memory kernel. We propose and numerically realize a numerically efficie...
We investigate the reversible diffusion-influenced reaction of an isolated pair in the presence of a non-Markovian generalization of the backreaction boundary condition in two space dimensions. Following earlier work by Agmon and Weiss, we consider residence time probability densities that decay slower than an exponential and that are characterized by a parameter 0 < σ ≤ 1. We calculate an exac...
We study the non-Markovian dynamics of a two-mode bosonic system interacting with two uncorrelated thermal bosonic reservoirs. We present the solution to the exact microscopic Master equation in terms of the quantum characteristic function and study in details the dynamics of entanglement for bipartite Gaussian states. In particular, we analyze the effects of short-time system-reservoir correla...
