A closer look at rock physics models and their assisted interpretation in seismic exploration

Assisted Seismic Matching: Joint Inversion of Seismic, Rock Physics and Basin Modeling

In this study, we apply advanced numerical optimization techniques to extend the work of Imhof and Sharma (2005, 2006) to integrate geological and geophysical data and infer the sedimentary parameters that produce a match to seismic data. In particular, we seek to match not just event timing (phase) but also reflection strength (amplitude). This inverse problem of quantitatively matching presen...

A Closer Look at Preduction

In a recent paper Jun Arima formalises the idea of preduc-tion { a non-monotonic schema providing a common basis for inductive and analogical reasoning. We examine some of the implications of this schema, as well as its connections with prototypes and conceptual spaces. A generalised version of his schema is motivated and developed to address diiculties with asymmetry and disjuncts.

A Closer Look at HMAC

Bellare, Canetti and Krawczyk [BCK96] show that cascading an ε-secure (fixed input length) PRF gives an O(εnq)-secure (variable input length) PRF when making at most q prefix-free queries of length n blocks. We observe that this translates to the same bound for NMAC (which is the cascade without the prefix-free requirement but an additional application of the PRF at the end), and give a matchin...

A Closer Look at Trumping1

According to Schaffer (2000a), “trumping preemption” is a category of redundant causation distinct from early and late preemption and from overdetermination. I show that the putative causal difference between causal processes in cases thought to be trumping preemption generates early preemption or overdetermination rather than trumping. I draw a novel lesson from cases thought to be trumping: t...

How Judo Professionals Win and Lost in Competition: A Closer Look at Gender, Weight, Technique, and Gripping

Background. Judo coaches and athletes must understand the relevant technical content of the competition to improve their judo skills in Taiwan. Therefore, this study intends to explore the current situation and differences in scoring techniques of outstanding judo players and the impact on the victories or defeats of scoring techniques. Objectives. The purpose of this study is to explore the d...
