Computer Simulation Of Livestock Housing Design, Leslie Lloyd Christianson

Electronic Theses and Dissertations

Computer simulation requires theoretical and empirical mathematical relationships describing different aspects of heat and moisture transfer for livestock confinement buildings. Relationships with various degrees of sophistication exists that adequately describe these heat and moisture transfers. Using these relationships with climatic data, environmental requirements, construction characteristics, material properties and economic data, a computer technique can be developed to mathematically model energy requirements for operating confinement livestock environments. This technique should base ventilation rates on moisture removal, temperature control and animal comfort criteria to minimize unnecessary energy consumption. However, no such computer model currently exists that determines and employs optimal ventilation rates …

Electrical Safety In The Hospital, William Ray Engle

Electronic Theses and Dissertations

Electrical safety has become n important part of hospital management. The potential danger to patients and staff has increased, as health care becomes more sophisticated. Due to the unique situation that exists in hospitals, most hospital personnel do not understand the problems that occur. The problem is greater in smaller hospitals that do not have the time, money or qualified personnel to deal with the problem. Hospital electrical safety is not a complex problem. A basic safety program can be initiated if the personnel have a basic understanding of electricity and its effects on the body. Many nurses in the …

Edge Detection And Adjacency Classification In Digital Data Via The Gradient Vector, Michael John Russell

Electronic Theses and Dissertations

Detection of edges in imagery represented by the matrix of data and classification of the data surrounded by an edge are investigated. An edge detection algorithm is developed and used to locate edges in digitized imagery. An algorithm called the adjacency classifier is developed to classify all groups in adjacent data points that are surrounded by edges. These two algorithms incorporate three important characteristics of the gradient vector: high gradients are inherent at edges, low gradients are inherent at edges, low gradients are inherent within homogeneous objects and gradient vector directions are perpendicular to the edge direction. Computer programs which …

Three-Dimensional Ultrastructure Determination Of Wheat Streak Mosaic Virus Pin Wheel Inclusion Bodies Through The Use Of Analytic Geometry, And High Resolution Electron Microscopy And Signal Analysis And Dissemination Equipment Studies Of Ultrastructure, Raymond Leroy Mernaugh

Electronic Theses and Dissertations

This study was undertaken for several reasons. The primary reason for the study was to determine the three-dimensional shape of the viral pin wheel inclusion in order to confirm or deny the three-dimensional structures put forth by Edwardson (15), Andrews and Shalla (1); or to establish another different pin wheel inclusion three-dimensional shape yet undescribed in previous literature. A secondary reason for the study lies in the fact that if this technique described in this paper was deemed acceptable, it could be employed to determine quickly, from two-dimensional electron micrographs, the three-dimensional ultrastructural shapes of many features seen in electron …

Mathematical Models Of Postweaning Growth, Feed Intake And Carcass Composition Of Beef Cattle, Hoon Song

Electronic Theses and Dissertations

A computer model was developed to evaluate the energetic efficiency of postweaning beef production of various biological types of cattle fed rations with different energy densities. In Section I, a mathematical model was developed to estimate voluntary feed intake for growing cattle from weaning to slaughter. The mathematical model included effects of differences in energy density and crude fiber content of the ration and in breed and degree of maturity of cattle on feed intake. When gastrointestinal tract distension controlled feed consumption, the primary factors determining feed intake were (1) rate of excretion of digesta, (2) rate of digestion, (3) …

Effects Of P.L. 566 Stream Channelization On Wetlands In The Prairie Pothole Region, Ronald E. Erickson

Electronic Theses and Dissertations

The Wild Rice Creek Watershed project, in North and South Dakota was constructed under authority of the Small Watershed Protection and Flood Prevention Act (P.L. 83-566 as amended). Structural measures included 24.7 miles of channelization and four floodwater retarding dams. To measure the degree that channelization influenced drainage of prairie wetlands, drainage rates in a channelized tributary were compared to rates in an unchannelized tributary of Wild Rice Creek. Channelization had a direct impact on wetlands by channel drainage reduction of overbank flows, and by providing drainage outlets. Indirect (secondary) wetland losses are believed to have occurred outside of the …
