The California Department of Food and Agriculture Rodent Bait Surcharge Program is actively funding studies to develop and register safe, effective and practical ground squirrel baits. Under this program, Genesis Laboratories has conducted eight studies since 1994 designed to fulfill registration requirements for existing baits and to develop new baits. Areas of research include field efficacy,...

The prediction of slope stability was performed using artificial neural networks (ANNs) in this work. factor safety determined by numerical analysis used to develop ANN’s data sets. inputs the network are height, applied surcharge and angle. Correlation coefficients between ANNs outputs showed feasibility for successfully modelling predicting issues. training phase is improved a genetic algorit...

Résumé. Les index et les vues matérialisées sont des structures physiques qui accélèrent l’accès aux données d’un entrepôt. Ces structures engendrent cependant une surcharge de maintenance. Par ailleurs, elles partagent le même espace disque. Les travaux existants dans le domaine de la sélection d’index et de vues matérialisées traitent ces deux structures de manière isolée. Dans cet article, n...

This study examined the incidence and determinants of quantity price discounts and quantity price surcharges in the German food sector through a bivariate probit, using recent consumer scanner survey data. Selectivity bias was corrected for in estimating the degree of quantity price surcharge and quantity price discount, using Heckman’s procedure. The findings reveal that almost 10% of the inve...
