Cover pebbling numbers and bounds for certain families of graphs

Given a configuration of pebbles on the vertices of a graph, a pebbling move is defined by removing two pebbles from some vertex and placing one pebble on an adjacent vertex. The cover pebbling number of a graph, gamma(G), is the smallest number of pebbles such that through a sequence of pebbling moves, a pebble can eventually be placed on every vertex simultaneously, no matter how the pebbles are initially distributed. The cover pebbling number for complete multipartite graphs and wheel graphs is determined. We also prove a sharp bound for gamma(G) given the diameter and number of vertices of G.Comment: 10 pages, 1 figure, submitted to Discrete Mathematic

Domination Cover Pebbling: Structural Results

This paper continues the results of "Domination Cover Pebbling: Graph Families." An almost sharp bound for the domination cover pebbling (DCP) number for graphs G with specified diameter has been computed. For graphs of diameter two, a bound for the ratio between the cover pebbling number of G and the DCP number of G has been computed. A variant of domination cover pebbling, called subversion DCP is introducted, and preliminary results are discussed.Comment: 15 page

Recollecting Turbulence: Catastrophe and Sacrifice in the History of My Life by Henry Darger

This study of The History of My Life the 5,086 page autobiographical text by the outsider artist/author Henry Darger, uses non-linear modes of analysis, such as chaos and complexity theory, to explore the meaning of Darger\u27s epic narrative. Beginning with the idea that turbulence, seemingly chaotic, actually comes about as a compensatory restructuring of inadequate or unstable system dynamics, this study goes on to show that, as both influence and effect, turbulence is found at every level of Darger\u27s life and art, both in theme and structure. My Life is a prime example: an extended narrative describing a cataclysmic tornado, in which the text itself manifests turbulent properties of the storm it describes. Darger\u27s particular narrative madness is, in fact, an attempt to put turbulence into service as an alternative system of meaning, in contrast to failed social and religious systems of which he was the product. Henry Darger\u27s work provides us with the challenge of exploring new ways of finding meaning in narrative. This study uses traditional literary criticism coupled with a pattern analysis of redundancy to explore some of Darger\u27s primary themes

Livestock Industry Facilities and Environment: Swine Breeding Systems—the MO-Flex System

The MO-Flex Swine Building System allows for any production stage (Farrowing, Nursery, Grow-Finish and Breeding/Gestation) to be built using the same structural building shell design.https://lib.dr.iastate.edu/extension_ag_pubs/1169/thumbnail.jp

Livestock Industry Facilities and Environment: Swine Breeding Systems—the Lubbock System

The Lubbock System places weaned sows in crates with a boar placed in a pen directly behind them. Usually one boar is housed behind five or six sows. The boar pen is used not only to house the boar but for breeding. Females are backed into the breeding pen when estrus is detected. Generally all five sows are not from the same weaning group. This prevents the boar from being over-used.https://lib.dr.iastate.edu/extension_ag_pubs/1168/thumbnail.jp

Open Geoscience Data Models: end of project report

This report describes a three year knowledge exchange project, OpenGeoscience Data Models, which was funded by the Natural Environment Research Council (NERC) Knowledge Exchange programme. The project was aimed to encourage an open sharing of geoscience data models amongst a community of Geological Survey Organisations (GSOs), industry and academics. The data model is a key part of successful information management because it provides a centralised description of the meaning and inter-relationships of the information
