Speech Training And Speech Activities In Institutions Of Higher Education In Taiwan, Chang Yuh-Sheng

Electronic Theses and Dissertations

An M.A. thesis in speech on the status of speech training in Taiwan, China, is proposed. From personal experience, this author has discovered some difficulties which Chinese students meet when they take up speech in American universities. The chief reason for this might be that the Chinese students who study speech in American universities and colleges have a somewhat limited knowledge of the speech areas and an. inadequate background of speech training. Since speech courses are elective in most of the universities in Taiwan, the students' interest in participating in speech activities, such as speech contest and ·dramatic performance, has …

Buckling Loads For Partially Embedded Piles, David Allen Wahlstrom

Electronic Theses and Dissertations

Piles are common structural elements used to transmit loads through weak or compressible surface soils to lower, more suitable soil strata. They are relatively small diameter shafts that are forced into the ground. Typical examples of pile utilization can be found at nearly any site where a major structure is being constructed. Many waterfront structures are built on partially embedded piles. In this case, the pile transfers the load of the structure to the lower soil strata and also serves as a column for the portion of the structure above the mud line. Many bridges and buildings are also supported …

Finite-Difference Solution For Flow Over A Rough Porous Plate With Mass Transfer, Hwai-Way Wen

Electronic Theses and Dissertations

The study of flow over a plate with surface blowing or suction has become very important during recent years due to the increased interest in modifying the temperature or flow characteristics of the boundary layer. Many investigators have studied laminar and turbulent boundary layer flows over smooth surfaces; however, in practical applications, especially under high free stream velocity, the surface cannot be considered hydraulically smooth, and the fluid in turbulent rather than laminar. In this study, the numerical solution for turbulent flow over a rough porous plate with variable surface mass transfer is presented.

Application Of Remote Sensing Techniques To Monitoring Soil Moisture, Hal D. Werner

Electronic Theses and Dissertations

During the 1970 growing season, research was conducted to investigate the relationship between remote sensing imagery and soil moisture. Extensive aerial and ground truth data were collected and studied in order to evaluate the moisture supply and water use. The three hectare study site, located on the South Dakota State University James Valley Research and Extension Center, contained irrigated and non-irrigated sorghum and two fallow treatments.

Experimental Investigation Of Shock Boundary Layer Interaction For Two-Dimensional And Axisymmetric Flow, A. Shawki Zahran

Electronic Theses and Dissertations

A supersonic wind-tunnel has been constructed using an 8 inch by 10 inch single stage jet vacuum ejector with a capacity of handling 0.4 lb/sec air at 4 inches Hg absolute suction pressure. A Toepler Schlieren system with 10-inch diameter parabolic mirrors has been set up for flow pattern visualization. The same apparatus was developed to obtain multi-colored views of the flow pattern. That was accomplished by placing an equilateral prism in front of the light source located at the focal plane of the first parabolic mirror. A spectrum was thus produced at the focal plane of the second parabolic …

Screening Electrocardiograms Using Hotelling's Method Of Principle Components, Edward G. Schwartz

Electronic Theses and Dissertations

Considerable use is presently being made of computers to classify electrocardiograms (ECGs) into various heart defect categories. An example of such a program is the "Electrocardiographic Analysis Program" developed jointly by the Mayo Clinic and IBM. In one of Dr. Caceres published reports, he tells of using a computer program which involves 5,000 instructions. Dr. Caceres does not say whether this is a commercial program or one of bis own. His description does place this program in the same general category as IBM's. These programs have the common criteria of examining the ECG for the same information that a cardiologist …

Electronic Theses and Dissertations

Description of the Problem For nearly everyone in our society, remunerative work has provided a meaningful role. It also provided an avenue for the attainment of respect, dignity, and the essentials of the "good life." On the other hand, unemployment has necessitated reliance on programs for the indigent and unemployed. The central focus of this study was the Janus-headed problem of unemployment and underemployment. The approach was oriented to a level of organization which has not previously been adequately explored. Unlike most of the studies which have attempted to meliorate the exigencies of unemployment, this study focused on the needs …

Movements And Habitat Use By Hen Pheasants During Brood Rearing, Lynn E. Hanson

Electronic Theses and Dissertations

Land-use patterns characteristic of prime pheasant range in the Great Plains and prairie region have 50-75 percent of the land under cultivation according to Kimball et. al. (1956). Farmland is pheasant habitat, and the production of pheasants is therefore greatly influenced by farming practices. Considerable research has been done on rates of pheasant production, nest success, and cover preferences for nesting. However, little information has been obtained on movements and cover preferences for brood rearing. Most studies of the type of cover utilized by pheasant broods have been based on roadside and random field observations. Kozicky and Hendrickson (1951) carried …

An Investigation Of The Effects Of Instantaneous Jockeying In Queues By Simulation, B. Radindranath

Electronic Theses and Dissertations

In today's world, waiting lines formed by people, machines and other types of units are commonplace. Queues form whenever the current demand for a service exceeds the current capacity to provide that service. In many cases, the interarrival times or service times are not constants, but involve distributions from which the values occur randomly.

A waiting line causes concern when there is an economic value associated with it. A waiting line may have a negative monetary value if units leave without service, or if units have costs as they wait. Idle service facilities may also have a negative monetary value …

An Evaluation Of An Aerated Lagoon System Treating Combined Dairy And Domestic Wastes During Summer Operation, Douglas M. Skie

Electronic Theses and Dissertations

The Water Quality Act of 1965 and the adoption of the subsequent state water quality standards emphasized the general public's concern for the control of water pollution; for it has become the goal of our nation to maintain all American waters in a suitable condition for domestic and industrial supply, for recreation and for other beneficial uses. It is for these reasons that many communities have been faced with the problem of constructing new sewage treatment facilities or expanding present operations. The use of stabilization ponds as a means of providing sewage treatment has been the practice of many small …

The objective of the investigation was three-fold: (1) to examine the influence of negative pore pressure on the irregularly shaped compaction curve by pore pressure measurements; and (2) to correlate pore pressure measurements with experiments using a surface tension reducing agent together with water; and …

Nonlinear System Identification Using An Analog Technique, G. N. Govindan

Electronic Theses and Dissertations

The prime purpose of this thesis project is to investigate and to implement Kohr's method. Kohr's method of identification was selected for study mainly because of the easy accessibility of the analog computer, in addition to the other advantages mentioned above. In this thesis the method of Kohr is shown to apply to the identification of single-valued nonlinearities. However, it is also shown in the work to follow that the method does not apply, in general, to double-valued nonlinearities. Further, an extension of this method is developed herein which enables the determination of system order. A number of examples illustrating …
