Temporal properties of avalanche dynamics
Slip avalanches occur in both crystalline and amorphous solids. Slip avalanches and avalanches in other systems are thought to be critical phenomena linked to a nonequilibrium phase transition. In this thesis we explore some temporal properties of experimental slip avalanche dynamics. These …

EXCESS NOISE STUDIES ON AVALANCHE PHOTODIODES
… range was constructed. Commercially available avalanche photodiodes (APDs) could be illuminated over the wavelengths 420 nm to 2 gm and the noise current spectrum from 10 Hz to 10 kHz could be measured by a phase sensitive detection system. The noise above normal shot noise in germanium, …

Fabrication and characterization of avalanche photodetectors
Avalanche photodetectors are important for imaging applications because of their high sensitivity and low noise levels. For imaging applications, however, a two-dimensional array of APDs is required, and there are many fabrication issues involved in making such an array over a large area. In this …

An avalanche emergency plan for Broken River
This dissertation looks generally at avalanche rescue practices both in New Zealand and overseas. It aims to demonstrate the necessity for such practices and establish a background from which the main part of this work - Part 2- An Avalanche Emergency Plan for Broken River is based upon. It …

3D Camera Based on Gain-Modulated CMOS Avalanche Photodiodes
… concept of range camera exploiting linear-mode avalanche photodiodes as in-pixel demodulating detectors. Due to photocurrent gain modulation, avalanche photodiodes can combine optical sensing and light signal demodulation in a single device. The main advantage of the avalanche photodiode …

Automated avalanche mapping with deep learning: from satellite to webcam imagery
Humans have been exposed to snow avalanches ever since they inhabited or travelled through mountainous regions. For centuries, ways of managing risk and mitigating damage due to avalanches have been limited. For example, forests prevented the release of avalanches, protecting the villages below. In …
