USGS warns of increased rain-induced landslide risks

Multi-stage Statistical Landslide Hazard Analysis: Rain-Induced Landslides

Recurrence of rain-induced landslides is controlled by the repetition of rain events. Therefore, rainfall induced landslide hazard analysis is more complicated than a conventional rainfall frequency analysis, and requires multi-stage procedures. It requires a susceptibility analysis to divide a region into successive classes at the first stage. Then, the relationship between the probability of ...

An Early Warning System for Regional Rain-Induced Landslide Hazard

Landslide in alpine regions often causes heavy losses of both human lives and properties, most of the landslides are induced by heavy rainfall. In this paper, we put forward an early warning system of rain-induced landslide. From 2002, we carried on the demonstrative work of landslide monitoring and early warning in Yaan, Sichuan Province, China, and constructed the first county-scale landslide...

securitization of mortality risks in life annuities

insurers have in the past few decades faced longevity risks - the risk that annuitants survive more than expected - and therefore need a new approach to manage this new risk. in this dissertation we survey methods that hedge longevity risks. these methods use securitization to manage risk, so using modern financial and insurance pricing models, especially wang transform and actuarial concepts, ...

Rain: Reversible Addition with Increased Nonlinearity

This paper proposes a reversible, balanced and nonlinear vectorial Boolean function called ‘Rain’. Traditional integer addition modulo 2 has several features like reversibility, balancedness and nonlinearity. However, the bias for the best linear approximation of the output bits and their linear combinations is quite high. This leads to several attacks on stream cipher like NLS, which employs a...
