The purpose of the study was to compare the visual-motor performance
of college students who reported ingestion of certain drugs with
those college students who reported no drug ingestion. The study
drugs included the following drugs or groups of drugs: tobacco,
alcohol, marijuana, LSD, mescaline, barbiturates, and amphetamines.
A total...
A steady-state computer simulation was developed for the
Chemico Urea Process which is owned and operated by Reichhold
Chemicals, Inc., St. Helens, Oregon. The DISCOSSA executive system
was used to process information input and output and to automatically
converge the complex recycle calculations in this process.
The models developed in...
Fluid simulation is an interesting research problem with a wide range of applications including mechanical engineering, special effects in movies and games, and scientific simulation. Due to the complex nature of typical fluid flow equations, there are circumstances where a full volumetric fluid simulation may not be necessary to generate...
The asymptotic convergence acceleration method used in steady
state process simulation is examined in detail, and a criterion is
developed to decide when it should be applied. The criterion is related
to the rate of convergence of each variable and does not require any
prejudgment of its tolerance level by...
Most flexible manufacturing systems (FMS) presently in use have generated only modest productivity increases in proportion to capital in vested in the process, or they have not been favorably reviewed when compared to the investment costs of other improved manufacturing systems. This thesis presents a simulator program which will assist...
Potential water scarcity and drought conditions are predicted in and around Eugene, Oregon due to decreased snowpack and subsequent decreased snowmelt in the Western Cascade Mountains. This phenomenon was triggered by a long-term trend of warmer winters scientifically linked to global climate change patterns (Dalton et al. 2013). Numerous stakeholders,...
