Volatiles and Geochemical Fingerprinting of Plagioclase-Hosted Melt Inclusions from Mid-Ocean Ridge Lavas: Determination of Depth of Crystallization and Melt Composition in the Lower Crust

Creator:: Kotash, Alisa K.
Abstract:: The global mid-ocean ridge system is the largest magmatic system encompassing over 75% of the Earth’s total volcanism. As magmas ascend through the vertically variable oceanic crust, melts begin to crystallize and diversify and subsequently erupt at the surface. The interpretation of these erupted products observed on the seafloor requires...

Enabling safety-informed design decision making through simulation, reasoning and analysis

Creator:: Jensen, David Charles
Abstract:: While many organizations claim to "put safety first," safety is rarely considered early in the design process when system-level architectural decisions are made. Instead, system design follows an abstraction-to-detail process to first meet functional and then performance requirements. Following this process, safety assurance occurs in the later stages of design...
