US Classification:

705 26, 705 27

Abstract:

An interactive merchandising program includes two or more program segments that are organized in a series. Each program segment in the series includes at least one time-limited offer for sequential presentation to the customer. The customer is required to undertake some action with respect to each program segment without knowing the identity of offers in program segments yet to be presented. If an offer is accepted within the time limit of the offer, the merchandising program terminates and the customer's acceptance of the offer is processed. If the customer declines a presented offer, the offer is withdrawn. The merchandising program proceeds to the next program segment in which the customer is presented the next time-limited offer. In this manner, the customer is provided an interactive experience that invites considered decision-making on the part of the customer.

Abstract:

Method for generating an effective, efficient, and stable absorbing boundary condition in finite-difference calculations, such as model-simulation of predicted seismic data. The top surface and optionally the bottom surface of the computational domain or grid are treated with one or more layers of PML (), preferably 1D PML, assuming an orthorhombic medium in the PML implementation (). The side surfaces are handled with one or more ABC layers (). Further advantages may be realized by tapering earth model symmetry axis on the top and bottom of the model toward the vertical (). The invention provides a beneficial compromise between reducing artifacts in the image or physical property model and computational efficiency and stability.
