ERI Summer 2017 Fellowship Report
Introduction Ocean island basalts (OIB) are thought to sample the Earth’s deep mantle, whereby thermochemical plumes entrain lower mantle material and bring it to the surface where it erupts. By measuring the isotopic compositions of global OIB—which record the isotopic compositions of OIB mantle sources—geochemists can “map” the isotopic heterogeneity of the Earth’s deep mantle (e.g., Gast et ...
متن کاملERI Summer Fellowship Report : Nicoletta Christina Browne
Over summer 2017, I continued my research on dikes emplaced during the waning stages of the Neoproterozoic-Ordovician Ross Orogen, a continental arc along the present day location of the Transantarctic Mountains in Antarctica. The dikes intrude calc-alkaline plutons constituting the main intrusive phase as well as metasedimentary rocks formed during early stages of orogenesis. These dikes compr...
متن کاملMétodo ERi*c - Engenharia de Requisitos Intencional
The aim of this paper is to present the Intentional Requirements Engineering Method ERi*c, which is a contribution to Goal Oriented Requirements Engineering (GORE). ERi*c is based on the intentionality concept as applied by the i* Framework. Intentionality reflects organization actors’ motivations and interests and is represented in the models by goals and softgoals. The singularity of the prop...
متن کاملA Logic for evision a &iv eri
We present a logic for belief revision in which revision of a theory by a sentence is represented using a conditional connective. The conditional is not primitive, but rather defined using two unary modal operators. Our approach captures and extends the classic AGM model without relying on the Limit Assumption. Reasoning about counterfactual or hypothetical situations is also crucial for AI. Ex...
متن کاملSIMBA’s view of the Eri disk
We present the first observational confirmation for an extended circumstellar dust disk around Eri. The observations were obtained with the bolometer array SIMBA at the 15 m radio telescope SEST in Chile and measure the dust continuum at 1.2 mm. The emission, with a total flux of 21.4 mJy and a rms of 2.2 mJy/beam, is resolved to a deconvolved size of 27. ′′4 which corresponds to 88 AU. No clea...
