A yield model for dryland wheat production
(1971)
Seasonal evapotranspiration from dryland and irrigated wheat plots at Goodwell, Oklahoma during a three year period (1964-1967) could not be adequately described, without the inclusion of a drainage model, from data ...
Optimal grain sorghum irrigation strategies in a dynamic, stochastic environment
(1978)
Agricultural production and associated economic effects of irrigation on the Texas High Plains are seriously threatened by a rapidly declining groundwater supply and a swift upward trend in energy costs. To optimize the ...
A queueing model for the simulation of a port grain elevator
(1978)
Transferring grain from land-based modes of transport to ocean carriers, port elevators represent a substantial portion of the total transportation charges for moving grain from the surplus producing regions of the United ...
Ocean color, a theoretical study using matrix operator theory
(1982)
Matrix Operator theory has been extended for application to "Ocean Color" related problems. Required to extend the theory, specialized quadrature methods and both reflection and transmission operators, representing the ...
Mean yield prediction when predictor variables are subject to error
(1978)
In the linear regression model for regressing the mean yield of a crop (wheat) on predictor variables which are based on meteorological records from official weather stations and a technology time trend, the classical ...
On the theory of some stochastic compartmental systems in ecological work
(1978)
The first and second order cumulants of some multi-compartment stochastic models important to ecological problems are derived. The models investigated are the n-compartment irreversible, catenary model and the n-compartment ...
An economic model of the demand and supply of votes : some tentative empirical results
(1976)
The electoral process is an integral part of democratic decision-making. It is traditionally viewed as the one means by which those governed make known their preferences regarding the rules by which they wish to be ...
The generalized handicap wager market for football bets : theory and evidence
(1977)
Gambling is a near universal past time that takes on many varied and interesting market forms. One such interesting market is the handicap wager market for football bets, an organized market in which bets are placed on ...
The effect of employee retention on the demand for on-the-job training
(1977)
Most models of the demand for on-the-job training do not consider on-the-job training in the context of the demand for other inputs. Furthermore, the impact on employee retention of industry structure, employee characteristics, ...
An application of stochastic compartmental theory to modeling plant growth and crop yield
(1985)
The cumulant generating functions are derived for the n-compartment irreversible catenary systems for constant transfer rates and for time-dependent transfer rates. Furthermore higher order residence time moments or survival ...
