Hydrodynamic Cucker-Smale model with time delay and obstacle avoidance
Frontiers in PhysicsWe study a hydrodynamic Cucker-Smale-type model incorporating both time delays and obstacle potentials. The model governs the evolution of velocity and density fields of the system, where delayed interactions drive alignment and obstacle potentials ...

Quantitative recurrence statistics and convergence to an extreme value distribution for non-uniformly hyperbolic dynamical systems [PDF]
, 2016 For non-uniformly hyperbolic dynamical systems we consider the time series of maxima along typical orbits. Using ideas based upon quantitative recurrence time statistics we prove convergence of the maxima (under suitable normalization) to an extreme ...

International Journal of Adaptive Control and Signal Processing, EarlyView.This article proposes a convergent adaptive observer for a damped wave PDE and an infinite‐dimensional ODE coupled in cascade using sampled‐in‐space ODE state measurements. The proposed observer estimates the distributed states of the PDE and ODE along with unknown PDE parameters and spatial input.

Hyperbolic Systems of Partial Differential Inclusions [PDF]
, 1990 This paper is devoted to the study of first-order hyperbolic systems of partial differential inclusions which are in particular motivated by several problems of control theory, such as tracking problems.

Additive Gaussian Process Regression for Predictive Design of High‐Performance, Printable Silicones
Advanced Engineering Materials, EarlyView.A chemistry‐aware design framework for tuning printable polydimethylsiloxane (PDMS) for vat photopolymerization (VPP) is developed using additive Gaussian process (GP) modeling. Polymer network mechanics informs variable groupings, feasible formulation constraints, and interaction variables.

Julia and Mandelbrot Sets for Dynamics over the Hyperbolic Numbers
Fractal and Fractional, 2019 Julia and Mandelbrot sets, which characterize bounded orbits in dynamical systems over the complex numbers, are classic examples of fractal sets. We investigate the analogs of these sets for dynamical systems over the hyperbolic numbers.

On a Stochastic Hyperbolic System in Linear Elasticity [PDF]
SIAM Journal on Mathematical Analysis, 2000 A Cauchy problem for a linear stochastic hyperbolic system \[ u_{tt}(t,x) = A(t,x,D_{x})u(t,x) + F(t,x)\xi(t,x), \quad (t,x)\in (0,\infty)\times\mathbb R^{n}, \tag{1} \] with zero initial conditions \(u(0,\cdot) = u_{t}(0,\cdot) =0\), is considered. In the equation (1), \(u = (u_1,\ldots,u_{n})\), \(F\) is a matrix-valued locally bounded measurable ...

Intertwining operators for symmetric hyperbolic systems on globally hyperbolic manifolds
, 2021 In this paper, a geometric process to compare solutions of symmetric hyperbolic systems on (possibly different) globally hyperbolic manifolds is realized via a family of intertwining operators.

Advanced Engineering Materials, EarlyView.This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.
