Dynamics of crystallization in hard-sphere suspensions
Physical Review E, 1996Density fluctuations are monitored by small-angle light scattering during the crystallization of 0.22-\ensuremath{\mu}m-radius, hard colloidal spheres. Measured structure factors show an intensity maximum at finite-scattering vectors. The shape of the intensity distribution scales at early times during nucleation and growth and again at large times ...

Hard Gamma as Probe of Nuclear Dynamics
Acta Physica Hungarica A) Heavy Ion Physics, 2002Experimental results concerning the Ni-58 + Ni-58 at 30 MeV/u and Ni-58 + Au-197 at 30 and 45 MeV/u reactions are presented. The emission mechanism of hard photons has been exploited to get information on the time evolution of the reactions. From the measured hard gamma multiplicity associated to different classes of heavy residues a quantitative ...

Hard, flexible and dynamic constraint satisfaction
The Knowledge Engineering Review, 1999Constraint satisfaction is a fundamental artificial intelligence technique offering a simple yet powerful representation. An increasing amount of attention has recently been paid to the development of constraint satisfaction techniques, and it has become clear that the original formulation of a static Constraint Satisfaction Problem (CSP) with hard ...

Dynamical processes in hard-sphere fluids
Physical Review A, 1987For a classical fluid of hard spheres the nine hydrodynamic time-correlation functions between the microscopic density, longitudinal velocity, and temperature are calculated theoretically on the basis of the revised Enskog theory for all densities and wave numbers.

The dynamic hardness is defined as the ratio of the normal driving force to the normal displacement of a rigid spherical indenter. An instrument to measure this quantity has been developed in which the displacement is sensed by a seismic-displacement pickup and the driving force is produced by the inertial reaction at the midpoint of a free-free ...

Anomalous dynamics at the hard-sphere glass transition
Soft Matter, 2014We use X-ray photon correlation spectroscopy to study the dynamics of hard sphere suspensions and report the emergence of ergodicity restoring anomalous intermittent relaxation modes in the highest concentration suspension that is estimated to be above the glass transition concentration.

Abstract The dynamic hardness of a metal may be defined, by analogy with static hardness, as the resistance of the metal to local indentation when the indentation is produced by a rapidly moving indenter. In most practical methods the indenter is allowed to fall under gravity on to the metal surface.

A simple two-dimensional model, in which uniform hard spheres are made to move steadily and apparently nearly at random, is described. At low sphere density the model exhibits ``gas-like'' behavior. As the density is increased the behavior becomes more ``liquid-like'' and then ``crystallization'' occurs. Many dynamic atomic phenomena, believed to occur
