The presence of feedback in an inputoutput system
associated with an oceanographic phenomenon is determined. A
testing procedure to determine the presence of feedback is given.
The ordinary transfer function model is determined not to be
appropriate in modeling the system. The two and three stage least
squares methods are...
The crop rotation decision is important to farmers because of its
impact on profitability, financing and risk exposure. This thesis
addresses the problem of farm level crop rotation selection under perfect
and imperfect knowledge of prices, yields and costs. The problem
is addressed by first estimating production functions for irrigated...
Parallel programming is the major stumbling block preventing the parallel processing industry from quickly satisfying the demand for parallel computer software. This research is aimed at solving some of the problems of software development for parallel computers. ELGDF is a graphical language for designing parallel programs. The goal of ELGDF...
For the purpose of investigating the fundamental nature of the
interannual oscillation observed in the tropical Pacific in conjunction with
El Nino/Southern Oscillation (ENSO), the Comprehensive Ocean
Atmosphere Data Set was analyzed. Based upon this analysis, an
"intermediate" tropical atmosphere-ocean coupled model was developed.
For reason of their particular importance...
This dissertation is concerned with hypothesis testing for
fixed effects in mixed linear models. Our primary emphasis is on
mixed models when the class of covariance matrices has what we
call a rich linear structure. Such models include mixed ANOVA
models and regression models with heteroscedastic variances. For
the majority...
The primary purpose of the present study was to investigate the effect of peer presence upon the health-related physical fitness test scores of college students. A total of 312 undergraduate college students, 156 males and 156 females, 18 through 29 years of age, randomly selected from the physical education activity...
The behavior of six herbicides in soil was studied under controlled laboratory conditions. Sorption of bromacil, chiorotoluron and diuron was assessed by the batch equilibration procedure over a broad range of aqueous phase sorbate concentration. Linear equilibrium sorption constants (K[subscript p]) were slightly higher at 4° C than at 25°...
Changes of density occur naturally in phase transition processes and introduce the bulk movement of material. It is customary in analyzing such problems to disregard this unpleasant complication and assume the densities to be equal. However, such changes are unavoidable and for one-dimensional problems the complexities introduced by this bulk...
