Long bridges tend to develop large deformations under the
action of intense dynamical loads such as wind or earthquakes.
Unless these deformations are controlled in some fashion, the
structure might suffer damage or even collapse. One possible
solution to this problem is to apply external forces to the
An experimental investigation of factors effecting
scheduling a system of parallel, non-identical processors
using a series of experimental designs was carried out.
System variables included were processor capacities
relationships, sequencing and assignment rules, job size, and
product demand distributions. The effect of the variables was
measured by comparing mean flow...
A greenhouse experiment was conducted in 1991 and in
1992 to determine the effect of soil water pressure on
potato (cv Russet Burbank) plant growth and infection by
Verticillium dahliae. Soil water pressures of -0.01,
-0.03, -0.08, or -0.15 MPa were combined factorially with
two inoculum concentrations, 0 or 10...
The purpose of this study was to explore and describe
the nature of local school-community human service agency
collaboration undertaken to address the needs of at-risk
youth. The study focused on the experience of four youth
services teams in two Oregon counties.
A qualitative, multiple-case study approach was used as...
