Item A Single-Cylinder Internal Combustion Engine Test Unit for the Engineering Laboratory(North Dakota State University, 1962) Strege, Loren DouglasThe study of the reciprocating internal combustion engine is of prime importance to the student engineer. In our present civilization, the number of units and the total rated power of internal combustion engines in use is far greater than that of all other prime movers combined. Many basic engineering problems are present in the study of the operation of internal combustion engines. A number of mechanical and electrical devices have been developed to aid the engineer in his studies of engine performance. The purpose of this project is to provide the Mechanical Engineering Department of the North Dakota State University with an addition to its laboratory facilities which will enable the student to do additional experimental work in the internal combustion engines field.Item A study of the job and educational experiences of North Dakota vocational agriculture graduates who received the State Farmer degree from 1960 through 1965(North Dakota State University, 1969) Phillips, Terrance GeorgeIt was the purpose of this study to determine the job and educational experiences of North Dakota vocational agriculture graduates who received the State Farmer degree from 1960 through 1965. The specific objectives of the study were to determine: 1. Their present job or educational status, 2. The highest level and nature of their formal educational experiences, 3. The number of different types or grades of jobs they had held, 4. Their present geographic location. This study was limited to gathering the evidence needed to attain the stated objectives. The State Farmer degree recipients represent a select group of Future Farmers of America (FFA) members. It was not intended to be a study in depth of any particular occupational or educational characteristic or factor related thereto. Nor was the study to analyze the occupational and educational choice of the entire FFA membership in North Dakota or make inferences concerning all vocational agriculture graduates during the time period 1960 through 1965. Because of the limits of the scope of this study and the time element involved, no control group was used and therefore no comparisons were made.Item Growth and Development of Native Range Plants in the Mixed Grass Prairie of Western North Dakota(North Dakota State University, 1963) Goetz, HaroldThis study was initiated to secure quantitative data on growth characteristics of the major species in the mixed grass prairie of western North Dakota; to determine the extent and range in yearly variations in growth patterns of the species and of the type as a whole; to assess the general influence of climate as a cause for seasonal and yearly variations in growth patterns; and to interpret the data obtained in terms of their possible application to the practical grazing management of these grasslands.Item Impedances of a Cubical Quad Antenna(North Dakota State University, 1965) Choong, Tsi-lungRectangular loop antennas and short electric dipoles are two of the oldest antennas in existence. In 1888, twenty years after Maxwell invented his famous Maxwell's equations, Hertz used these two antennas to prove that high frequency electric energy sources could radiate electro- magnetic waves. The "Cubical Quad" or, simply, "Quad" antenna is a development of the rectangular loop antenna. It consists of a pair of square loops, one-quarter wavelength on a side or one wavelength around the periphery; one loop being driven and the other used as a parasitic reflector. The separation between the two is usually of the order of 0.15 to 0.2 wavelength, with the planes of the loops parallel. While studying the properties of this antenna, it was discovered that little had been done to develop it from a theoretical aspect. The purpose of this thesis is to obtain values of the self and mutual impedances existing in such an antenna array. The values are obtained from mathematical analysis and experimental measurements and may be used in field pattern and gain calculations.
