An algorithm for large-scale nonliner knapsack : problems and extensions
(1980)
In this dissertation, an algorithm was developed to solve large scale discrete nonlinear knapsack problems (NKP) with multiple resource constraints. The algorithm is essentially a dynamic programming technique in a sense ...
Identification and forecasting of the potential for the occurrence of extended-range VHF-UHF transhorizon propagation from synoptic-scale data
(1980)
An objective method is presented for identification of tropospheric areas with a potential for supporting extended-range VHF-UHF transhorizon propagation (ERTP), and for forecasting the potential for changes in this structure ...
Kirchhoff integral applied to two-dimensional seismic modeling of a growth fault in the Niger delta region
(1980)
Over seventy percent of the oil and gas fields found in the delta region is associated with growth faults. Recognition of this type of fault system therefore will play an important role in future petroleum exploration and ...
A systems analysis of dual dairy and beef production herds
(1980)
The milk and beef offtake of a herd of Colombia's North coast was predicted by simulation with the Texas A&M Cattle Production System Model. Basic response surfaces were established for genetic potentials of milk yield of ...
The effects of a percentage depletion allowance on vertically integrated mineral firms and industries : theory and evidence
(1980)
This dissertation investigates two controversial issues concerning the effects of a percentage depletion allowance upon vertically integrated mineral firms and industries. One controversial issue concerns the effect of ...
Analytic solutions to linear, time-dependent fission product deposition models for isothermal laminar, slug, or multiregion flow conditions
(1983)
The time-dependent convective-diffusion equation with radioactive decay is solved analytically in axisymmetric cylindrical geometry for laminar and slug velocity profiles under isothermal conditions. Concentration dependent ...
Theoretical and observational study of Langmuir circulation
(1981)
Craik (1977) showed from the theory developed by Leibovich (1977) that cellular roll motion similar to that found in Langmuir cells can develop as an instability due to the interaction of surface waves and currents. Solutions ...
Dynamic impacts of socio-economic development in rural Texas
(1985)
Several development policies and programs have been enacted to improve the economic vitality, social well-being and quality of life in rural communities. Predominant among these is the attempt by many rural communities to ...
An analysis of alternative farm policies for cotton
(1985)
Over the last twenty years, Texas cotton acreage has ranged from 4 million to 7.8 million acres. In many years, Texas acreage represents almost half the total U.S. acreage planted to cotton. Because Texas accounts for a ...
Simulation of the energy, carbon, and water balance of a fluid-roof greenhouse
(1983)
The energy, water, and CO(,2) balance of a greenhouse was analyzed with two simulation models: an existing one that simulated the flows of energy and mass in a greenhouse, based on a single leaf crop representation, and ...
