An on-line algorithm for semantic forgetting
No full textOntologies that evolve through use to support new domain tasks can grow extremely large. Moreover, large ontologies require more resources to use and have slower response times than small ones. To help address this problem, we present an on-line semantic forgetting algorithm that removes ontology fragments containing infrequently used or cheap to relearn concepts. We situate our algorithm in an extension of the widely used RoboCup Rescue platform, which provides simulated tasks to agents. We show that our agents send fewer messages and complete more tasks, and thus achieve a greater degree of success, than other state-of-the-art approaches
Cotton Packer.
No full textPatent for an automatic cotton packer that provides a new method to packing cotton. This mechanism can be controlled automatically or by hand. As the cotton leaves the gin, it is packed automatically
Forgetting Fragments from Evolving Ontologies
No full textOntologies underpin the semantic web; they define the concepts and their relationships contained in a data source. An increasing number of ontologies are available on-line, but an ontology that combines information from many different sources can grow extremely large. As an ontology grows larger, more resources are required to use it, and its response time becomes slower. Thus, we present and evaluate an on-line approach that forgets fragments from an OWL ontology that are infrequently or no longer used, or are cheap to relearn, in terms of time and resources. In order to evaluate our approach, we situate it in a controlled simulation environment, RoboCup OWLRescue, which is an extension of the widely used RoboCup Rescue platform, which enables agents to build ontologies automatically based on the tasks they are required to perform. We benchmark our approach against other comparable techniques and show that agents using our approach spend less time forgetting concepts from their ontology, allowing them to spend more time deliberating their actions, to achieve a higher average score in the simulation environment

MARKET POWER IN BEEF PACKING: FEEDLOT "CAPTURE" AND ITS CAUSES
No full textConcentration in the beef packing industry has been rising for the past 25 years. Many studies of market power in beef packing are based on the conjectural variations framework, which depends on accurate estimates of packer input and processing costs. We propose an alternative measure of packer behavior which does not rely on estimates of packer costs. We also suggest how this measure could be used to draw tentative conclusions regarding packer behavior.Agribusiness, Marketing,

Open hole packer and running procedure for hot dry rock reservoir testing
No full textAn acute need for open hole packers for high pressure, high temperature operations at the Fenton Hill, Hot Dry Rock (HDR) Geothermal Site has existed since 1981. Cemented-in-liners were used instead of packers while packer technology was brought up to HDR requirements. A reservoir development and evaluation program has just been completed with 5 successful open hole packer runs. These 5 successful runs were the result of: (1) R and D leading to improved packer materials and design, (2) an improved understanding of the interactions between the packer assembly and its hostile down hole environment, and (3) a carefully planned logging, sampling and coring program to locate packer setting depths (packer seats). 5 refs

THE EFFECTS OF INDUSTRY STRUCTURE ON PRICE: A CASE IN THE BEEF INDUSTRY
No full textThis study estimates the influence of concentration and other structural variables on the price of slaughter cattle. Cross-sectional data were used to estimate a single equation model which included, in addition to traditional factor demand variables, packer concentration and a measure of market power exerted by feedlots. Results suggest that packer concentration has had a significant and increasing negative impact on fed cattle prices during the years of analysis, 1972 and 1977.Industrial Organization, Livestock Production/Industries,
