Source Estimation from Broadband Regional Seismograms
Recently developed source inversion techniques do not take full advantage of the broadband nature of regional seismograms. The reason is that Green's functions generated from fiat-layered models are not correct for the complicated propagational phenomena associated with realistic crustal structure. The inversion is usually performed by removing short periods and inverting only selected portions...
متن کاملBiodiversity Hotspots and Zones of Ecological Transition
Biodiversity hotspots are areas of high priority for conservation (Reid 1998). They may be selected on the basis of their local species richness, degree of concentration of rare species (Prendergast et al. 1993) or the two measures combined with some assessment of urgency for conservation action (Myers et al. 2000). More targeted approaches identify " hotspots of complementarity " on the basis ...
متن کاملExcimer ablation design and elliptical transition zones.
PURPOSE To describe the rationale behind elliptical and other transition designs used with the excimer laser. SETTING Casey Eye Institute, Oregon Health Sciences University, Portland, Oregon, USA. METHODS Ablation zone designs were analyzed for the number of transition points for myopia and hyperopia. The advantages and disadvantages of elliptical transition zones are demonstrated graphical...

متن کاملThin Discs, Thick Discs and Transition Zones
Accretion onto a compact object must occur through a disc when the material has some initial angular momentum. Thin discs and the thicker low radiative efficiency accretion flows (LRAFs) are solutions to this problem that have been widely studied and applied. This is an introduction to these accretion flows within the context of X-ray binaries and cataclysmic variables. Accretion describes the ...
