Harmonic modes in a hard sphere fluid
Physical Review Letters, 1994The velocity time correlation function of a hard sphere fluid has been calculated using a generalized Langevin formulation of kinetic theory. When the memory function is approximated by its zero time value, the Langevin equation describes an overdamped harmonic oscillator in which the damping term arises from Enskog (uncorrelated collision) friction ...

Hard-aperture Kerr-lens mode locking
Journal of the Optical Society of America B, 1993Self-focusing by a Kerr nonlinearity in combination with an intracavity aperture creates a power-dependent loss in lasers, which has been used as a method for passive mode locking of lasers. An analytical treatment is presented that yields closed-form expressions for the modulation efficiency.

Critical dynamics near a hard mode instability
Zeitschrift f�r Physik B Condensed Matter, 1981Scaling hypothesis and a renormalization group procedure are formulated in the vicinity of the bifurcation point, where the behaviour is governed by inhomogeneous fluctuations. The working of the general ideas is illustrated in a model system in which the number of components of the complex order parameter field goes to infinity.

Hard mode stationary states generated by fluctuations
Zeitschrift f�r Physik B Condensed Matter and Quanta, 1978The influence of the fluctuations on the dynamics of open macroscopic systems is analysed for a class of two dimensional examples. The amplitudes of the fluctuations are themselves dependent on the macro-variables. It is shown that such random noises can generate temporal oscillations of the macro-variables.

Hardware Assisted ROP Detection Mode (HARD Mode)
2013Abstract : Return oriented programming (ROP) is a form of code-reuse attack employed in many modern exploitation attacks. Current defenses such as address-space randomization, structured exception handling, and memory space permissions have thus far proven only speed bumps for attackers. Utilizing new hardware capabilities in the upcoming Intel Haswell

Hard mode spectroscopy: The concept and applications
Phase Transitions, 1997Abstract Hard modes are, in the context of this review, optically active phonons which show systematic changes of their Raman and/or IR spectra when the structural properties of a material are changed (e.g. by heating, application of pressure or chemical reactions).

Chiral hard-surface waveguide mode transformer
IEEE Transactions on Microwave Theory and Techniques, 2000Field propagation in cylindrical axially corrugated waveguide filled with chiral medium is considered in this paper. The depth of the corrugation is a quarter-wavelength, making a hard-surface (HS) boundary. These eigenfields inside the chiral HS waveguide are circularly polarized.
