Tomography in the post-migrated domain is quickly becoming the standard approach for obtaining velocities in complex areas. The standard flow to update the velocity through tomography in the post-migrated domain begins by migrating the data using some initial velocity model. This migration method can be Kirchhoff (Etgen, 1990), downward continuation methods (Clapp, 2001b; Mosher et al., 2001), ...

We analyze the problem of choosing the w contestants who will win a competition within a group of n > w competitors when all jurors commonly observe who the w best contestants are, but they may be biased. We study conditions on the con…guration of the jury so that it is possible to induce the jurors to always choose the best contestants, whoever they are. If the equilibrium concept is dominant ...

Bacteria diversify nfectious bacteria often grow in their hosts as biofilms. Blaise Boles, Matthew Thoendel, and Pradeep Singh (University of Iowa, Iowa City, IA) now report that growth in biofilms causes Pseudomonas aeruginosa bacteria to diversify. The resultant diverse populations are probably more able to cope with changing environmental conditions, providing a bacterial correlate of the re...

The torsion rod characteristics of the Sulzer loom can be adjusted in zero position by means adjusting lever and actuator loom. In "Sulzer" projectile loom, movement intermediate member results axial to change according material rod. transmits a force exerted fixed sliding surface. However, described device some countries has serious drawback, because tuning drive acts on so that when is fired ...

With the continuous development of e-business, e-business distribution center operating mode is gradually changing. Small batch and more frequency is the characteristics of the e-business. The new characteristics gives birth to new distribution center picking mode. This paper analyzes disadvantaged of the business mode of the current e-business distribution center, put forward a new type of e-b...

This paper describes an approach to determine a layout for the order picking area in warehouses, such that the average travel distance for the order pickers is minimized. We give analytical formulas by which the average length of an order picking route can be calculated for two different routing policies. The optimal layout can be determined by using such formula as an objective function in a n...

We propose a simulated annealing algorithm specifically tailored to optimise total retrieval times in a multi-level warehouse under complex pre-batched picking constraints. Experiments on real data from a picker-to-parts order picking process in the warehouse of a European manufacturer show that optimal storage assignments do not necessarily display features presumed in heuristics, such as clus...

Mouse picking is the most commonly used intuitive operation to interact with 3D scenes in a variety of 3D graphics applications. High performance for such operation is necessary in order to provide users with fast responses. This paper proposes a fast and reliable mouse picking algorithm using graphics hardware for 3D triangular scenes. Our approach uses a multi-layer rendering algorithm to per...

Using data mining techniques, this study attempts to explore how a proper layout zoning following class-based storage enhances order picking efficiency over randomized storage. Association web statistics and association rule mining examines the relative intensity levels among various product categories. These findings serve as the layout for zoning of the storage area of α company, a pharmaceut...
