Advances in landslide nowcasting: evaluation of a global and regional modeling approach

The increasing availability of remotely sensed data offers a new opportunity to address landslide hazard assessment at larger spatial scales. A prototype global satellite-based landslide hazard algorithm has been developed to identify areas that may experience landslide activity. This system combines a calculation of static landslide susceptibility with satellite-derived rainfall estimates and ...

Advances in Value Theory

" Value, introduced by Lloyd Shapley in 1953, is a central concept in game theory and its applications. The value of a game to a player is best viewed as an a priori evaluation of his expected payoffs (in a similar way that the "utility" of a "gamble" or "lottery" is a measure ofthe.prospective outcomes). The Shapley value and its generalizations have been extensively studied, and continue to b...

Nowcasting for Rainfall Accumulation Prediction

Short-term prediction (nowcasting) of high-impact weather events can lead to significant improvement in warnings and advisories resulting in substantial savings of life and property. While nowcasting of precipitation has traditionally been done using radar reflectivity (Zh) data, research over the last decade indicates that using the specific differential phase (Kdp), defined as one-half the ra...

Collaborative Nowcasting for Contextual Recommendation

Mobile digital assistants such as Microsoft Cortana and Google Now currently offer appealing proactive experiences to users, which aim to deliver the right information at the right time. To achieve this goal, it is crucial to precisely predict users’ real-time intent. Intent is closely related to context, which includes not only the spatial-temporal information but also users’ current activitie...
