T the ripe age of eighty-four Lloyd Morgan has passed away. jje wag for many years the distinguished and greatlyeloved Principal of University College, and when the College deceived its charter in 1909 converting it into Bristol diversity Lloyd Morgan was designated the first Vicehancellor. He relinquished this office almost immediately, nd Sir Igambard Owen was appointed in his stead. His ecis...
The Agricultural Policy Environmental eXtender (APEX) model is capable of estimating edge-of-field water, nutrient, and sediment transport and is used to assess the environmental impacts of management practices. The current practice is to fully calibrate the model for each site simulation, a task that requires resources and data not always available. The objective of this study was to compare m...
Using the most recent atmospheric neutrino data, as well as short-baseline, longbaseline and tritium β-decay data we show that the joint interpretation of the LSND, solar and atmospheric neutrino anomalies in (3+1) sterile neutrino schemes is severely disfavored, in contrast to the theoretically favored (2+2) schemes.
The aphorism “All models are wrong but some are useful” (Box, 1978) sums up much of what ML is about. The assumptions we make in the Naive Bayes approach to sentimanet classification are wrong, but this is true of the assumptions made in all current formal models of human language (statistical or otherwise), with the possible exception of a few which are very restricted indeed. However, the que...
abstract: proverbs are of the language materials which of the food of any language depends on the quality and quantity of these same materials. in the present research, the researcher tried to present the ramsarian proverbs according to four variables of color, fruit, plantsand animals that selected from the book of the members of each of these four variables, put them into the spss system fo...
Large hurricanes and other catastrophic wind events such as tornados and severe downbursts are major natural disturbance agents impacting forests of the eastern United States as well as those of many other areas of the world. They often cause severe though highly variable tree damage across the affected landscape (e.g. Frelich and Lorimer, 1991 ; Peterson and Pickett, 1991 ; Walker et al. , 199...
We characterized five 0.21.1 ha gaps created by downbursts during Hurricane Opal in xeric oak forest at the Bent Creek Experimental Forest, Asheville. NC. Direction of windthrow was nonrandom in four of the five gaps, but differed among gaps suggesting that each was caused by an independent downburst. Windthrows reduced tree density by 19-39s and basal area (BA) by 3%53% within gaps. Most windt...
