Fling-step and forward directivity are two important characteristics of near-field earthquakes. Forward directivity occurs when the rupture propagates toward the site and arises in fault‐normal direction for strike‐slip faults. Fling-step is the consequence of permanent ground displacement imposed by near-field earthquakes and arises in strike-slip faults in the strike parallel direction. Fling...

We prove a symmetry relationship between floating-strike and fixed-strike Asian options for assets driven by general Lévy processes using a change of numéraire and the characteristic triplet of the dual process. We apply the same technique to prove a similar relationship between floating-strike and fixed-strike lookback options.

This paper proposes a method for detecting geomagnetic sudden commencement (SC) from a geomagnetic horizontal (H) component b y using lifting wavelet lters. Lifting wavelet lters are biorthog-onal wavelet lers containing free parameters. Our method is to learn such free parameters based on some training signals which c o n tain the SC. The learnt w avelet lters have the feature of training sign...

tion of techniques: chopping down the methodology jungle. Abstract In this article we discuss formalisation of techniques in the context of Information System Development methodologies. When such methodologies are developed, the primary goal is applicability. After the methodology has proven itself in practice, the methodology will be applied in more sophisticated situations, pushing the method...
