A soil temperature model for predicting the overwintering emergence of Heliothis zea and Heliothis virescens (Lepidoptera, Noctuidae)
(1985)
An existing, physically based, one dimensional numerical model for soil temperature and soil water content was adapted and validated with experimental data on soil temperature in the upper 100mm of the profile. A simpler ...
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 ...
Estimation of relative permeabilities from displacement experiments
(1985)
The estimation of relative permeabilities from displacement experiments by the parameter estimation method was examined. In using this method the relative permeabilities, which are continuous functions of saturation (a ...
Capital market in agriculture : a disaggregated structural model
(1985)
The objective of this study was to develop an econometric simulation model of the U.S. financial sector that emphasizes the linkages between the financial sector and the farm sector. Demand and supply equations for eight ...
A comparative study of the empirical impact of the joint estimation approach and the alternative selection approach for application to econometric models with a pure autocorrelation structure : the case of the General Fechner-Thurstone direct utility function
(1985)
This dissertation is an empirical, comparative study of the impact of two different approaches, the joint estimation approach and the alternative selection approach, in dealing with econometric models of a typical ...
A wafer scale cellular tree architecture
(1985)
Binary tree architectures are a good candidate for WSI because of the regular use of cells and local communication requirements. Unfortunately, a single critical failure can render an entire structure useless unless suitable ...
Texas Coastal Bend grain sorghum producers' fertilizer decisions under uncertainty
(1985)
Optimal (profit and utility maximizing) fertilizer levels are computed based on normative decision guides developed from experimental data on grain sorghum yield/fertilizer levels over an eight year (1977-1984) period, as ...
Effects of rigidity and internal flow velocity on marine riser dynamics
(1985)
It is well known that the internal flow may have a pronounced effect on the dynamics of a pipe conveying the fluid and may even cause dynamic instability. The objective of the present study is to examine the effect of the ...
High order variational solutions of time-dependent neutron transport problems
(1985)
High order numerical solutions of the time-dependent one speed neutron transport equation are developed using cubic hermite polynomial trial functions, variational techniques, and exponential matrix operators. Two new ...
Effects of variable force coefficients Cd and Cm on the dynamic response of a Tension-Leg Platform
(1985)
The Morison hydrodynamic force prediction equation is commonly used to compute the wave forces on offshore structures composed of "small members". The computations are carried out assuming that the force coefficients, C[d] ...
