A rational approach for incorporating needs into drainage system design
(1978)
The overall goal of this investigation was to develop a methodology for incorporating crop drainage requirements into subsurface drainage design schemes. The methodology developed was linked to the North Carolina State ...
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 ...
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 ...
A study of causal relationships, expectations, and the demand for money during three hyperinflations
(1978)
The theory of inflation and its effects on economic variables such as exchange rates and rates of change in the money stock has been developed to a large extent within the last twenty years. The recent inflationary pressure ...
A stochastic network simulation model for the Texas certificate of need review process as relates to general hospital bed expansion
(1978)
A review of the literature related to hospital utilization as well as the Texas Certificate of Need (CON) process revealed no comprehensive, consistent method for reviewing CON applications. To overcome this deficiency in ...
Prices, inventories, and capacity : a theoretical-empirical study of the downstream petroleum industry
(1978)
Petroleum is the major source of energy in our society today. Few, if any, products on the market are not either made directly from petroleum or produced by a process involving petroleum at least as a fuel. Neoclassical ...
Optimization of the second order logarithmic machining economics problem by extended geometric programming
(1978)
The theory of geometric programming is extended to include a new function with logarithmic exponents. The function, defined as a Quadratic Posylognomial (QPL) is a series of nonlinear product terms with positive coefficients ...
Supply and demand for slaughter beef in the U.S. : a disaggregated econometric approach
(1978)
Analyses of commodity supply and demand functions generally do not evaluate relationships within the components of the commodity. Such aggregative approaches sometimes lead to generalizations with ambiguous conclusions. ...
