A non-coercive Lyapunov framework for stability of distributed parameter systems

2017 IEEE 56th Annual Conference on Decision and Control (CDC), 2017
We show that the existence of a non-coercive Lyapunov function is sufficient for uniform global asymptotic stability (UGAS) of infinite-dimensional systems with external disturbances provided the speed of decay is measured in terms of the norm of the state and an additional mild assumption is satisfied. These additional assumptions cannot be dropped in

Coercive Control: Update and Review [PDF]

Violence Against Women, 2019
This article reviews the background, introduction, and critical response to new criminal offenses of coercive control in England/Wales and Scotland. How the new Scottish offense is implemented will determine whether it can overcome the shortcomings of ...

Growth and stability of highly coercive, highly textured NdFeB films

Digest of INTERMAG 2003. International Magnetics Conference (Cat. No.03CH37401), 2004
In this paper, for the thin film growth, we first examine the conditions necessary to obtain highly coercive, highly textured NdFeB films and then examine the stability of these films as this will be a crucial feature for the application of rare-earth magnets as thin films.

Dynamic coercivity and thermal stability of epitaxial exchange spring trilayers

Journal of Magnetism and Magnetic Materials, 2010
Abstract Exchange-coupled hard/soft magnetic nanocomposites have recently found a renewed interest in data-storage application as exchange spring media, also named exchange-coupled composite (ECC). Developed formerly to improve the energy density of a hard magnetic material by an intimate, direct exchange coupling to a soft magnetic phase with high ...

Novel equiaxed magnetite media with high coercivity and thermal stability

Journal of Applied Physics, 1992
Equiaxed magnetite media with coercivity of up to 1560 Oe, saturation and residual magnetizations of up to 83 and 50 emu/g, respectively, and squareness ratio of up to 0.61 have been developed by the modification of Mn and Co, and by proper annealings.

Computed Temperature Stability of the Remanence and the Coercivity of Nanoscaled Permanent Magnets

physica status solidi (a), 1998
For technical applications of high performance permanent magnets the stability of magnetic properties like the remanence and the coercivity over a large temperature range is a decisive prerequisite. This can be investigated by computational methods using the continuum theory of micromagnetism.

Stability in frictional unilateral elasticity revisited: an application of the theory of semi‐coercive variational inequalities

AIP Conference Proceedings, 2006
In this paper we show how recent results concerning the stability of semi‐coercive variational inequalities on reflexive Banach spaces, obtained by the authors in [3] can be applied to establish the existence of an elastic equilibrium to any small uniform perturbation of statical loads in frictional unilateral linear elasticity.

Effects of phosphorous doping on the stability of coercivity of cobalt-substituted acicular oxides

Journal of Applied Physics, 1995
The effects of P doping on the coercivity and magnetic-thermal stability of Co-substituted iron oxides have been investigated by means of magnetic measurements, torque curves, and Mössbauer spectra. It is found that the P doping of cobalt-substituted acicular oxides promotes the coercivity and the stability with temperature of the coercivity.

Thermal stability of the in-plane magnetic anisotropy and the coercivity of nanocrystalline CoFeNi films

Journal of Magnetism and Magnetic Materials, 2003
By choosing the right production parameters, in-plane, uniaxial anisotropy up to about 15 Oe (1250 J/m(3)) could be induced in electrodeposited layers of Co59Fe26Ni15. This compound consists of a mixture of FCC and BCC phases. The layers were magnetically soft and nanocrystalline with grain sizes of 10-15 nm.

Uniform Exponential Stability Analysis of Impulsive Linear Time-Invariant Systems on Banach and Hilbert Spaces: Non-Coercive and Coercive Stability Conditions

We consider the uniform exponential stability analysis of infinite-dimensional impulsive systems defined on a Banach or Hilbert space, whose flow is governed by a fixed $C_0$-semigroup generator and whose jumps occur at a prescribed time sequence.
