Geographic Concentration in U.S. Manufacturing Industries: A Dartboard Approach

by Glenn Ellison, Edward L. Glaeser - Journal of Political Economy
"... This paper discusses the prevalence of Silicon Valley–style localiza-tions of individual manufacturing industries in the United States. A model in which localized industry-specific spillovers, natural ad-vantages, and pure random chance all contribute to geographic concentration is used to develop a ..."

Individual Plant Examination of External Events Reference:

by An Exelon Company , 2000
"... In the reference letter, the NRC issued a Request for Additional Information (RAI) related to the Individual Plant Examination of External Events (IPEEE) assessments for fire events for the Braidwood Station and the Byron Station. As requested, we have focused our attention and responses on the trea ..."

INDIVIDUAL PLANT EXAMINATION- INTERNAL FLOODING REANALYSIS

by W. L. Stewart, Surry Power Station , 1991
"... Individual Plant Examination (IPE) for Surry Power Station. In subsequent meetings with the NRC, we committed to perform a reanalysis of the internal flooding vulnerability to quantify the conservatism in the analysis and provide written responses for the additional questions that were raised by you ..."

Radiosity and Realistic Image Synthesis

by M. Cohen, J. Wallace, J. Radiosity, In Artificial, Life Iii, C. G. Langton, Ed. Addison-wesley , 1993
"... this paper, such as the global distribution of radiative energy in the tree crowns, which affects the amount of light reaching the leaves and the local temperature of plant organs. The presented framework itself is also open to further research. To begin, the precise functional specification of the ..."

issues are not limited to the environment, but also arise in plant models. They become particularly relevant as the scope of modeling increases from individual plants to groups of plants and, eventually, entire plant communities. This raises the problem of selecting the proper level of abstraction

POSTERS- SESSION 5 Individual plant model

by Stefano Mazzoleni, Francesco Giannino
"... A physiological-architectural model of individual woody plants is presented. The model is implemented according to the most recent modelling technologies based on a declarative and modular approach. The methodology of modelling implementation is based on the integrated use of an advanced system dyna ..."

Measuring competition in plant communities where it is difficult to distinguish individual plants

by Christian Damgaard , 2011
"... Abstract A novel method for measuring plant-plant interactions in undisturbed semi-natural and natural plant communities where it is difficult to distinguish individual plants is discussed. It is assumed that the ecological success of the different plant species in the plant community may be adequa ..."

Growth and mortality of individual plants as a function of ‘available area

by Richard Mithen, John L. Harper, Jacob Weiner - Oecologia (Berlin , 1984
"... Summary. We looked at the relationship between "available area", as defined by Thiessen polygons around individual plants, and plant size and mortality in even-aged green-house populations of Lapsana communis L. Polygon area was a good predictor of plant weight in these populations. After ..."

Metabolomics Unravel Contrasting Effects of Biodiversity on the Performance of Individual Plant Species

by Christian Scherling, Christiane Roscher, Patrick Giavalisco, Ernst-detlef Schulze
"... In spite of evidence for positive diversity-productivity relationships increasing plant diversity has highly variable effects on the performance of individual plant species, but the mechanisms behind these differential responses are far from being understood. To gain deeper insights into the physiol ..."

Plants and productivity in international trade

by B. Bernard, Jonathan Eaton, J. Bradford Jensen, Samuel Kortum - The American Economic Review , 2003
"... We reconcile trade theory with plant-level export behavior, extending the Ricardian model to accommodate many countries, geographic barriers, and imperfect com-petition. Our model captures qualitatively basic facts about U.S. plants: (i) pro-ductivity dispersion, (ii) higher productivity among expor ..."
