Spatially-distributed coverage optimization and control with limited-range interactions [PDF]
, 2004 This paper presents coordination algorithms for groups of mobile agents performing deployment and coverage tasks. As an important modeling constraint, we assume that each mobile agent has a limited sensing/communication radius.

Stability Bias in Lagrangian (Back)tracking in Divergent Flows
Journal of Advances in Modeling Earth Systems, Volume 18, Issue 1, January 2026.Abstract Forward‐ and backward‐in‐time Lagrangian advection, used to determine fate and origin of material in the ocean, are mathematically consistent. However, their numerical computations are hampered by round‐off and truncation errors. Trajectory calculations are stable to errors (i.e., errors are dampened) in zones of velocity convergence and ...

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.A novel controller design integrates position error constraints using a barrier Lyapunov function, ensuring bounded tracking performance. The proposed control strategy ensures exponential convergence of tracking errors while preserving robustness against disturbances and uncertainties.

A Unified Approach to High-Gain Adaptive Controllers [PDF]
, 2009 It has been known for some time that proportional output feedback will stabilize MIMO, minimum-phase, linear time-invariant systems if the feedback gain is sufficiently large.

IET Signal Processing, Volume 2026, Issue 1, 2026.Formation control of multi‐autonomous underwater vehicle (AUV) systems is essential for collaborative ocean tasks such as environmental monitoring and resource exploration, but it is hindered by challenges like limited flexibility in formation transformation, model uncertainties, and unknown ocean current disturbances.

Floquet Stability Analysis of Ott-Grebogi-Yorke and Difference Control [PDF]
, 2008 Stabilization of instable periodic orbits of nonlinear dynamical systems has been a widely explored field theoretically and in applications. The techniques can be grouped in time-continuous control schemes based on Pyragas, and the two Poincar\'e-based ...

Large‐Amplitude Periodic Solutions to the Steady Euler Equations With Piecewise Constant Vorticity
Studies in Applied Mathematics, Volume 156, Issue 1, January 2026.ABSTRACT We consider steady solutions to the incompressible Euler equations in a two‐dimensional channel with rigid walls. The flow consists of two periodic layers of constant vorticity separated by an unknown interface. Using global bifurcation theory, we rigorously construct curves of solutions that terminate either with stagnation on the interface ...

Experimental Study of the Sampled Labyrinth Chaos [PDF]
, 2011 In this paper, some new numerical as well as experimental results connected with the so-called labyrinth chaos are presented. This very unusual chaotic motion can be generated by mathematical model involving the scalar goniometrical functions which makes

The legacy of the Cartwright–Littlewood collaboration
Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.Abstract Mary L. Cartwright and John E. Littlewood published a short “preliminary survey” in 1945 describing results of their investigation of the forced van der Pol equation ÿ−k(1−y2)ẏ+y=bλkcos(λt+a)$$\begin{equation*} \ddot{y}-k(1-y^2)\dot{y}+y = b \lambda k \cos (\lambda t+a) \end{equation*}$$in which b,λ,k,a$b,\lambda,k,a$ are parameters with k$k$
