Nonlinear H∞ Optimal Control Scheme for an Underwater Vehicle with Regional Function Formulation
Journal of Applied Mathematics, 2013 A conventional region control technique cannot meet the demands for an accurate tracking performance in view of its inability to accommodate highly nonlinear system dynamics, imprecise hydrodynamic coefficients, and external disturbances.

An uniform boundedness for Bochner-Riesz operators related with the Hankel transform [PDF]
, 2002 Let Hα be the modified Hankel transform Hα(f,x) = ∫0∞ Jα(xt)/(xt)α f(t)t2α+1dt, defined for suitable functions and extended to some Lp((0, ∞), x2α+1) spaces. Given δ > 0, let Mαδ be the Bochner-Riesz operator for the Hankel transform.

Ultimate boundedness of some third order ordinary differential equations [PDF]
, 2012 summary:We prove the ultimate boundedness of solutions of some third order nonlinear ordinary differential equations using the Lyapunov method. The results obtained generalize earlier results of Ezeilo, Tejumola, Reissig, Tunç and others.

Bioinspired Hydrogels with Broadly Programmable Mechanics for Soft‐Tissue Interfaces
Advanced Functional Materials, EarlyView.Sea cucumber‐inspired gelatin hydrogels are formed by directional freezing and mechanically programmed through subsequent ionic treatment. Multiscale characterization and modeling link ion‐regulated chain interactions to directional load transfer within the aligned hierarchical architecture.

Advanced Materials, EarlyView.Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.

Stability and uniform ultimate boundedness of solutions of a third-order differential equation
, 2010 This paper is concerned with uniform ultimate boundedness of solutions of a third-order nonlinear differential equation (1.1). Sufficient conditions under which all solutions x(t), its first and second derivatives tend to zero as t —∞, when p(t,x,x',x") =

Ultimate boundedness and robust stabilization of bilinear discrete-time systems
, 2011 In this paper nonlinear time-varying and bilinear discrete-time systems with additive bounded disturbances are considered. First, conditions guaranteeing uniform ultimate boundedness for time-varying nonlinear systems are established.

Advanced Materials, EarlyView.ABSTRACT The accelerating expansion of data‐centric technologies is sharply increasing the energy burden of information storage, placing unprecedented pressure on the efficiency of magnetic switching. Conventional field‐driven reversal, once the foundation of magnetic memory, has become impractical in modern architectures due to its high energy cost ...
