Store Managers – the Seismographs in Shopping Centres Store Managers – the Seismographs in Shopping Centres
Purpose: The aim of this paper is to investigate (1) the link between store managers’ evaluation of how customers assess a shopping centre and their own evaluation of the centre and, based on that, (2) the relevance of store managers in reflecting upon and informing the management and marketing practices of the local shopping centre management. Methodology: A conceptual model is developed based...
متن کاملStacking three-component seismograms
Standard stacking procedures are based on the combination of many scalar traces, and can exploit the coherency of arrivals between traces using non-linear methods. Such stacks can be used with some success for three-component data but do not exploit the vector character of the seismic wave¢eld. A set of stacking methods are introduced to work directly with three-component data and include inter...
متن کاملFinite - Difference Seismograms for Sh Waves
The accuracy of the fi!lite-difference method for generating synthetic seismograms of SH wave propagation in cylindrically symmetric media is discussed. The finite-difference method has the advantage that arbitrary density and velocity fields in the medium may be specified. A point source is generated by a simple transformation of a line source. The accuracy of the finite-difference seismograms...
متن کاملHistorical seismograms: Preserving an endangered species
The youth of seismology as a science, compared to the typical duration of seismic cycles, results in a relative scarcity of records of large earthquakes available for processing by modern analytical techniques, which in turn makes archived datasets of historical seismograms extremely valuable in order to enhance our understanding of the occurrence of large, destructive earthquakes. Unfortunatel...
متن کاملAn interactive program on digitizing historical seismograms
Retrieving information from analog seismograms is of great importance since they are considered as the unique sources that provide quantitative information of historical earthquakes. We present an algorithm for automatic digitization of the seismograms as an inversion problem that forms an interactive program using Matlab GUI. The program integrates automatic digitization with manual digitizati...
