Static analysers search for overapproximating proofs of safety commonly known as safety invariants. Fundamentally, such analysers summarise traces into sets of states, thus trading the ability to distinguish traces for computational tractability. Conversely, static bug finders (e.g. Bounded Model Checking) give evidence for the failure of an assertion in the form of a counterexample, which can ...

The 5 September 2012 M(w) 7.6 earthquake on the Costa Rica subduction plate boundary followed a 62-y interseismic period. High-precision GPS recorded numerous slow slip events (SSEs) in the decade leading up to the earthquake, both up-dip and down-dip of seismic rupture. Deeper SSEs were larger than shallower ones and, if characteristic of the interseismic period, release most locking down-dip ...

The main components which affect the earthquake damage grades classification of multistory masonry buildings and the damage characters are summarized and analyzed through the statistics and analysis of a large number of previous earthquake damage data. According to the standard of earthquake damage grades classification, the damage numbers of each component of multistory masonry buildings under...

A variety of user-friendly spreadsheet templates have been developed for geoscience studies. However, the use of the built-in matrix functions within spreadsheet programs, such as Excel, is not particularly straightforward, lowering the value of spreadsheet programs for matrix-based computations, such as multiple regression analyses. Therefore, this study first developed two applications for Ex...

Because of the availability of high-resolution satellite imagery, remote sensing data has become an attractive source of data for identifying post-earthquake damage. Recently, several semiautomated methods for earthquake damage detection have been developed. These methodologies fall into two general categories: change detection and thematic classification. In change detection, both preand post-...

| This paper describes the work currently developed at Heudiasyc and Liia within the Pro-Lab II demonstrator. This project started with the second phase of the European Prometheus/Pro-Art program. Its purpose is to develop an electronic co-pilot to assist the human driver. The global software architecture of the demonstrator, presented in 3], is structured in three main modules: perception , de...

In order to better research the role helicopter played in the earthquake rescue, a helicopter earthquake rescue mission modeling method based on multi-agent was proposed. The elements of the earthquake environment modeling were described. Typical helicopter rescue missions in earthquake relief were divided into three basic types, and the mission flow was carded. The division and function of age...

The development of seismic vulnerability evaluation standards for reinforced concrete buildings in Japan is briefly reviewed. Damage statistics are shown to indicate that severe damage was observed in a relatively small percentage of existing buildings even after damaging earthquakes in the world. Therefore, a simple screening procedure is necessary to identify such vulnerable buildings out of ...
