(Texas A&M University. Libraries, 1978)The major purpose of this dissertation is to consider and discuss a mathematical measurement theoretic foundation for financial accounting. First, certain of the philosophical writings in measurement theory are reviewed. ...
-
(Texas A&M University. Libraries, 1982)The approximation or interpolation of irregularly spaced data in two or higher dimensions is extremely difficult in contrast to the one dimensional case. No one method works well in all instances with the possible exception ...
-
(Texas A&M University. Libraries, 1979)Cattle producers typically react to cyclical prices by increasing the size of the breeding herd as price increases and decreasing it as price decreases. Current decisions to cull and/or replace cows are based on such data ...
-
(Texas A&M University. Libraries, 1978)Simulation of changes in production within an Andropoqon-Paspalum dominated grassland ecosystem of east-central Texas was based on 36 months of environmental and 20 months of biomass data. Simulation models utilizing ...
-
(Texas A&M University. Libraries, 1990)The United States has maintained a sugar import quota since 1982. This policy, while supporting U.S. producer prices and incomes at a high level, has caused consumers to pay more for sugar and has reduced the incomes of ...
-
(Texas A&M University. Libraries, 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 ...
-
(Texas A&M University. Libraries, 1982)Tourism is a complex and economically significant factor in the economy of many areas of the world including the United States. Investment decisions for tourism are often made without considering all salient factors. This ...
-
(Texas A&M University. Libraries, 1989)Numerous physical and mathematical models have simulated highly mature diapirism in which low density material moves upward through more dense material and then spreads out as a layer known as a canopy (Jackson and Talbot, ...
-
Analysis of a counterflow indirect evaporative cooling and liquid desiccant dehumidification system (Texas A&M University. Libraries, 1986)A solar-fired liquid desiccant cooling and dehumidification system has been proposed, analyzed and simulated on a digital computer. The entire study comprised of three distinct but related stages. The first phase of the ...
-
(Texas A&M University. Libraries, 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 ...
-
(Texas A&M University. Libraries, 1983)With growing realization of the limitations of available energy resources, systems requiring low energy are of considerable interest at the present time. Experimental and field test results show that indirect evaporative ...
-
(Texas A&M University. Libraries, 1979)This research concerns itself with the flow behavior in a computer-communication network that integrates data and voice classes of traffic. This behavior is analyzed as a queueing problem by modeling nodes and channels and ...
-
(Texas A&M University. Libraries, 1984)Most analyses of food consumption from household budget data assume that prices are constant in cross-section. However, if cross-section data have sufficient temporal and spatial dimensions, there is no a priori theoretical ...
-
(Texas A&M University. Libraries, 1983)SAMTAM--Sawmill Analysis Model from Texas A&M was developed in three versions: (1) in Fortran for a mainframe computer, (2) in Applesoft for the Apple II, and (3) for the TI-59 calculator. SAMTAM is better than other models ...
-
(Texas A&M University. Libraries, 1990)The EST approach is used to construct analytic, low-rank, separable approximations to the Reid soft core potentials. All previous efforts to approximate potentials by an energy-independent separable form are shown to be ...
-
(Texas A&M University. Libraries, 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 ...
-
(Texas A&M University. Libraries, 1988)Analytical modeling of heterogeneous reservoir systems is an important aspect of reservoir engineering and formation evaluation. Numerous analytical models have been presented in recent years to describe pressure and rate ...
-
(Texas A&M University. Libraries, 1988)A functional transformation method has been developed to be used with different techniques for solving separation problems which are difficult to converge. Problems of this kind consist of sets of nonlinear equations with ...
-
(Texas A&M University. Libraries, 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 ...
-
(Texas A&M University. Libraries, 1986)The Public Utilities Regulatory Policies Act (PURPA) requires electric utility companies with annual sales exceeding 500 million kilowatt-hours of electricity to report specific types of load research data to the Federal ...
