An evaluation of the use of an artificial neural network to analyze the effect of startup milk production on reproductive performance of high producing Holstein dairy cattle
(1994)
Through the use of an artificial neural network the analysis of reproductive performance in high producing dairy cattle using startup lactation information was evaluated. Data was obtained from monthly DHIA tapes and used ...
Wettability of porous media by nuclear magnetic resonance relaxation methods
(1994)
Wettability is a major factor which influences the distribution of multiphase fluids in reservoir rocks. However, the conventional methods for determining wetting characteristics of reservoir rocks are difficult and ...
Development of a predictive model for pavement roughness on expansive clay
(1994)
Expansive clays are the major cause of differential movements in shallow foundations. In highway pavements they are responsible for cyclic distortion of the riding surface resulting in a loss of road handling ability and ...
Using the family as a co-therapist : the therapeutic effectiveness of video-feedback in the context of Milan Systemic Therapy
(1994)
This study examined the comparative effects of circular questioning plus video-feedback versus circular questioning plus verbal-feedback upon a variety of perceptions held by family members. Five families were assigned to ...
Carbon and nitrogen mineralization from cowpea green manure and millet residue in Niger and under controlled conditions
(1994)
Lack of organic input is a major factor contributing to the deterioration o f the sandy Alfisols and Entisols in the Sahelian zone of West Africa. Cowpea [Vigna unguiculata (L.) Walp.] has great potential as green manure ...
Fundamental relationships of crack formation in expansive clay soils
(1994)
The cracks which form in expansive clay soils during desiccation, due to their unique swelling and shrinking property, greatly influences agricultural and geotechnical processes, such as water infiltration, solute movement, ...
A comparison between close-range computer mono-photogrammetry techniques for historical building documentation
(1994)
The purpose of this study was to compare the accuracy of documentation drawings produced by four computer close-range mono-photogrammetric techniques with that produced by hand measurements. It was hypothesized that there ...
A new approach for resolving certain linear optimization problems using separation theory
(1994)
This dissertation poses fundamentally new results based on separation theory to resolve a number of issues in linear optimization. First, redundancies present in a collection of linear inequalities are characterized, and ...
Reaction and EPR spectra of "MCl4.2PR3" (M=V, Nb, Ta) compounds and study of some amidato-bridged dirhenium compounds
(1994)
The reaction solution of triethylphosphine with MCl4 (M = V, Nb, Ta) has been reported to show electron paramagnetic resonance signals at both room temperature and low temperature. The axial behavior of the low temperature ...
Landscape study of bark beetle herbivory and the lightning disturbance regime
(1994)
The goal of the research described by this dissertation was to examine characteristics of the lightning disturbance regime in relation to herbivory by pine bark beetles. The first of two data sets consisted of five years ...
