An experimental study is described in which time-average local heat
transfer coefficients were obtained for arrays of horizontal tubes immersed
in a hot fluidized bed. Spatial-averaged heat transfer coefficients, computed
from local values, are also reported. Refractory particles with surface
mean diameters of 2.14 mm and 3.23 mm were fluidized...
A Land Evaluation and Site Assessment (LESA) Model was
developed for the forested soils of Lane County, in western Oregon,
based on soil potential ratings and indexes of parcel size and
adjacent and surrounding land use conflict. Lane County's economy
is heavily dependent on resource production uses of land for...
Products as diverse as soda-pop, fashion and
automobiles are selling to the tunes of classic and current
pop and rock music. The combination of MTV (Music
Television), the latest audio-visual technology, and the
replacement of movie stars by rock stars as the idols of
contemporary youth (Beckett, 1985; Hartman, 1987),...
The emission of sulfur oxides from anthropogenic sources represents a potential threat to terrestrial ecosystems. Sulfate, the most highly oxidized form of sulfur, is the most common form of inorganic sulfur in most soil environments. The sorption of sulfate may influence the alkalinity of the soil solution and as a...
Multiobjective Decision Making (MODM) has been
suggested for the solution of complicated decision
problems. Decision analysis in numerous areas, including
industrial energy and environmental planning, necessarily
requires consideration of multiple conflicting
objectives. MODM has been successfully applied to
a number of these problems of this type. Moreover, it
has the...
Several problems relating to linear programming modeling have
been identified: (1) model formulation, validation and explanation
are difficult and time consuming; (2) models must be frequently
updated and debugged; (3) flexibility is needed to specify the model
schema for a class of problems as a group; and (4) significant
differences...
