How can landslide risk maps be validated? Potential solutions with open-source databases
نویسندگان
چکیده
Landslides are a worldwide natural hazard that cause more damage and casualties than other hazards. Therefore, social economic losses can be reduced through landslide quantitative risk assessment (QRA). In the last two decades, many attempts of analysis on various scales have been performed; nevertheless, major difficulty QRA lies in how precise reliable should to useful. For this reason, paper, we analyzed different freely available datasets some products previous research assess soundness outcomes performed by recent slow-moving landslides Arno River basin (Central Italy). The validation process was carried out comparing abovementioned components selected (hazard risk). obtained results showed robust correlation between most testing dataset components, highlighting accuracy QRA.

Many open-source projects land security fixes in public repositories before shipping these patches to users. This paper presents attacks on such projects—taking Firefox as a case-study—that exploit patch metadata to efficiently search for security patches prior to shipping. Using access-restricted bug reports linked from patch descriptions, security patches can be immediately identified for 260...

متن کاملGrowing up with stability: How open-source relational databases evolve
Like all software systems, databases are subject to evolution as time passes. The impact of this evolution can be vast as a change to the schema of a database can affect the syntactic correctness and the semantic validity of all the surrounding applications. In this paper, we have performed a thorough, large-scale study on the evolution of databases that are part of larger open source projects,...
