The Effect of Avalanching in a Two-Species Ripple Model [PDF]
Advances in Complex Systems, 2001 This paper discusses a simple two-species ripple model with avalanching. The effect of the avalanching term is investigated numerically, and is found to be crucial in producing realistic ripple profiles.

The effectiveness of avalanche airbags
Resuscitation, 2014Asphyxia is the primary cause of death among avalanche victims. Avalanche airbags can lower mortality by directly reducing grade of burial, the single most important factor for survival. This study aims to provide an updated perspective on the effectiveness of this safety device.A retrospective analysis of avalanche accidents involving at least one ...

Model of the photon-avalanche effect
Physical Review B, 1993The photon-avalanche effect, which involves both absorption from a metastable intermediate level and cross-relaxation energy transfer, introduces a new trend in the achievement of efficient up-conversion lasers. In this paper, we report a quite general theoretical treatment of this process which is successfully applied to the case of ${\mathrm{LiYF}}_ ...

Finite-size effects of avalanche dynamics
Physical Review E, 2002We study the avalanche dynamics of a system of globally coupled threshold elements receiving random input. The model belongs to the same universality class as the random-neighbor version of the Olami-Feder-Christensen stick-slip model. A closed expression for avalanche size distributions is derived for arbitrary system sizes N using geometrical ...

Effect of avalanche build-up time on avalanche photodiode sensitivity
IEEE Journal of Quantum Electronics, 1985A calculation method for the receiver sensitivity of an avalanche photodiode is considered, taking into account avalanche build-up time and carrier transit time, in addition to the CR time constant. Actual receiver performance is estimated in a high data rate region of up to 10 Gbits/s for germanium avalanche photodiodes, applying the measured ...

2021 3rd International Conference on Signal Processing and Communication (ICPSC), 2021
To obtain high efficiency in encryption techniques many factors plays vital role. Avalanche effect is one of the most important factor which is calculated as number of flipped bits by small change in key, or plaintext or initialization vector. This paper provides performance analysis of encryption techniques considering avalanche effect as a key role ...

Noise effects in avalanche photodiodes
IEEE Transactions on Education, 2000The usual formula for the excess noise produced in a simple avalanche photodiode may be introduced in a particularly simple manner by taking advantage of the fact that the ionization coefficients usually encountered in practice are often regarded as constant throughout the device for any specific applied bias voltage.

Infrared detection scheme with the photon avalanche effect
Applied Optics, 2003We present a new infrared (IR) detection scheme based on the infrared quantum counter (IRQC) detector and utilizing the photon avalanche process. At the time of its discovery, the phenomenon of photon avalanche was considered a limitation rather than an advantage for the development of IRQC.

Effect of volume fraction on granular avalanche dynamics
Physical Review E, 2014We study the evolution and failure of a granular slope as a function of prepared volume fraction, ϕ(0). We rotated an initially horizontal layer of granular material (0.3-mm-diam glass spheres) to a 45° angle while we monitor the motion of grains from the side and top with high-speed video cameras.
