    Open-Source ANSS Quake Monitoring System Software

    ANSS stands for the Advanced National Seismic System of the U.S.A., and ANSS Quake Monitoring System (AQMS) is the earthquake management system (EMS) that most of its member regional seismic networks (RSNs) use. AQMS is based on Earthworm, but instead of storing files on disk, it uses a relational database with replication capability to store pick, amplitude, waveform, and event parameters. The replicated database and other features of AQMS make it a fully redundant system. A graphical user interface written in Java, Jiggle, is used to review automatically generated picks and event solutions, relocate events, and recalculate magnitudes. Add‐on mechanisms to produce various postearthquake products such as ShakeMaps and focal mechanisms are available as well. It provides a configurable automatic alarming and notification system. The Pacific Northwest Seismic Network, one of the Tier 1 ANSS RSNs, has modified AQMS to be compatible with a freely available, capable, open‐source database system, PostgreSQL, and is running this version successfully in production. The AQMS Software Working Group has moved the software from a subversion repository server hosted at the California Institute of Technology to a public repository at gitlab.com. The drawback of AQMS as a whole is that it is complex to fully configure and comprehend. Nevertheless, the fact that it is very capable, documented, and now free to use, might make it an attractive EMS choice for many seismic networks

    Studio e sviluppo di un progetto per la portabilitĂ  multipiattaforma di un sistema per la visualizzazione di ambienti virtuali tridimensionali interattivi

    Get PDF
    Lo scopo di questa tesi è di investigare le soluzioni esistenti per la portabilità multipiattaforma, in particolare analizzando lo specifico caso di studio della conversione di un grande progetto, relativo ad una complessa applicazione multimediale nativa per l’ambiente MS Windows, in un progetto multipiattaforma, discutendo dei problemi incontrati e delle soluzioni adottate. Objective of this thesis is to investigate the existing solutions available for cross-platforming, analyzing in particular the specific case study of the conversion of a large project, related to a complex multimedia application native to the Microsoft Windows environment, into a multi-platform project, discussing the problems encountered and the solutions adopted
