Risk and Avalanche Rescue
The risk to rescuers is of serious concern for the International Commission for Alpine Rescue (ICAR). For good reason, since ICAR receives annually reports of fellow rescuers injured or killed while on missions. In avalanche rescue many call outs occur when the general danger rating is 3 or higher and where conditions are further deteriorating. This means that both the approach and the accident...
متن کاملAvalanche risk management using GRASS GIS
The GRASS system has been used to evaluate avalanche risk. This has been done by combining heterogeneous data. Val di Pejo, located in the north-western Trentino, an Italian alpine region which shows frequent and sometimes huge avalanche phenomena, has been selected as test area. A morphologic risk has been defined in those areas where the slope is between 28° and 55° for a minimum surface of a...
متن کاملNeural Imaging Using Single-Photon Avalanche Diodes
Introduction: This paper analyses the ability of single-photon avalanche diodes (SPADs) for neural imaging. The current trend in the production of SPADs moves toward the minimumdark count rate (DCR) and maximum photon detection probability (PDP). Moreover, the jitter response which is the main measurement characteristic for the timing uncertainty is progressing. Methods: The neural imaging pro...
متن کاملModelling of High Quantum Efficiency Avalanche Photodiode
A model of a low noise high quantum efficiency n+np Germanium Photodiode utilizing ion implantation technique and subsequent drive-in diffusion in the n layer is presented. Numerical analysis is used to study the influence of junction depth and bulk concentration on the electric field profile and quantum efficiency. The performance of the device is theoretically treated especially at the wave-l...
متن کاملAvalanche Size Distribution in the Toom Interface
We present numerical data of the height-height correlation function and of the avalanche size distribution for the three dimensional Toom interface. The height-height correlation function behaves samely as the interfacial fluctuation width, which diverges logarithmically with space and time for both unbiased and biased cases. The avalanche size defined by the number of changing sites caused by ...
