- Abstract/Description

When a heat pipe operates with a large temperature difference between the two ends, the vapor liquid combination is not in thermodynamic equilibrium. The experiments showed that the vapor liquid mixture is in a higher state of saturation at the condenser as compared to other sections of the pipe. Correlations were obtained that relate the coefficient of thermal coupling alpha to the evaporator flux and mass of NCG (non-condensable gas). As mass of NCG is increased in the heat pipe, the...
Show moreWhen a heat pipe operates with a large temperature difference between the two ends, the vapor liquid combination is not in thermodynamic equilibrium. The experiments showed that the vapor liquid mixture is in a higher state of saturation at the condenser as compared to other sections of the pipe. Correlations were obtained that relate the coefficient of thermal coupling alpha to the evaporator flux and mass of NCG (non-condensable gas). As mass of NCG is increased in the heat pipe, the thermal coupling coefficient alpha decreases. The evaporator heat flux is directly proportional to alpha. The coefficient alpha is related to the pressures and temperatures at the evaporator, condenser and the adiabatic sections. In conclusion, for heat pipes that do not operate in thermodynamic equilibrium, correlations were obtained between the operating conditions of the heat pipe, the evaporator heat flux and the mass of NCG.

Show moreMost of recent studies indicate that people are negatively predisposed toward utilizing autonomous systems. These findings highlight the necessity of conducting research to better understand the evolution of trust between humans and growing autonomous technologies such as self-driving cars (SDC). This research therefore presents a new approach for real-time trust measurement between passengers and SDCs. We utilized a new structured data collection approach along with a virtual reality (VR) SDC simulator to understand how various autonomous driving scenarios can increase or decrease human trust and how trust can be re-built in the case of incidental failures. To verify our methodology, we designed and conducted an empirical experiment on 50 human subjects. The results of this experiment indicated that most subjects could rebuild trust during a reasonable timeframe after the system demonstrated faulty behavior. Furthermore, we discovered that the cultural background and past trust-related experiences of the subjects affect how they lose or regain their trust in SDCs. Our analysis showed that this model is highly effective for collecting real-time data from human subjects and lays the foundation for more-involved future research in the domain of human trust and autonomous driving.

Show moreKnowledge of vehicle source heights is necessary for noise barrier design, but currently, no reliable method exists to measure this parameter. This study involves the development of system to evaluate source heights using a method known as the source breakdown technique. The first phase of this study consists of the demonstration of the source breakdown technique on loudspeakers in an anechoic chamber. The second phase involves tests outdoors using loudspeakers in the presence of ground reflections. The third phase consists of an assessment of sources on a single vehicle. In the first two phases, source breakdown results are compared with actual measurements for verification. Noise and source mislocation errors are considered, as well as methods to reduce their detrimental effects.

Show moreThe objectives of this investigation were: (1) to find the relationship between the sand movement velocity and the force induced using a small model basin, (2) to find and build a sand transport meter and apply the relation from (1) together to measure the velocity fluctuation and quantity of sand movement on the beach. The idea of model basin comes from the fluidized bed concept. Using this model, the complicated influences that happen during the field measurement can be prevented, and a prime relation can be applied to the field measurement. In the model basin experiment, the force induced by the drag is related to the velocity of power around 0. 62. In the field measurement on the beach, the initial goal could not be reached because of the appearance of the unexpected low frequency signal which was initiated by the wave motion itself. However, the device and idea of this experlment were proven to be good and feasible.

Show moreThe purpose of the present study was to investigate the variable effects of different testing frequencies upon the achievement of college students of three levels of ability. Frequency of testing was selected for research because of the role it serves in the behavioral system of instruction initiated by Fred Keller. Past research on the effect of increase in test frequency has produced ambivalent results, in part because of repeated methodological errors, in part because the individual learning level of each S has not been a primary concern in the design of these studies. The basic hypothesis of this experiment was that the effects of increased quiz occurrence depend on previous academic history. Results were discussed in relation to the practice of infrequent testing. Such procedures most handicap those with poor backgrounds. Those institutions serving this type of student should re-evaluate their examination methods and consider the use of frequent quizzes. Further suggestions were made to extend the investigation of the functional relationship between instructional techniques and individual histories.

Show moreIn this thesis the flow of vibration power between two coupled, finite plates of arbitrary thicknesses is considered using a Mobility Power Flow (MPF) approach. The plate structure is divided into substructures and mobility functions are determined for the independent substructures. Power flow expressions are derived based on continuity of forces and displacements. The solution presented here considers the effects of both in-plane waves and out-of-plane waves. The solution is applicable to frequencies below the first mode of thickness-shear vibration. The results obtained show that at low frequencies, the out-of-plane waves dominate in the transmission of vibrational power. However, at high frequencies or for thick plates, the in-plane waves play a significant role in the power transmission through the plate.

Show moreA theoretical model has been developed to compute the vertical array directional response for surface generated ambient noise in a shallow water environment. The cross spectrum function is based on a normal mode solution to the wave equation in which the effective depth approximation is used to yield closed form solutions for two distinct mode types. The effective depth modes encompass the shallowest grazing angles where the bottom reacts as a pressure release surface to the incident plane waves. The rigid bottom solution takes over as the grazing angle increases and attenuation becomes significant. The computed vertical array beam output was compared to other models including a fast field wavenumber integration method and a multipath eigenray method with mixed results. The results indicated good agreement for both comparisons with the realization that the effective depth model is sensitive to the approximation discontinuity at the mode transition point.

The modal parameters and mode shapes were determined for the first six diametral modes, the first concentric mode, and the first rigid body shaft mode. The disc consisted of a circular aluminum plate with eight equally and symmetrically spaced radial cutters on one face of the disc and eight equally spaced peripheral cutters located on the rim of the disc midway between the angular locations of the radial cutters. All cutters were of tool steel. The safe area of operation is determined to be between 3000 rpm and 3600 rpm. The experimental setup and procedure Is described in detail with particular emphasis on validation of assumptions required for the analytical approaches used in calculating the modal data.

The forcing functions can be determined from the frequency-wavenumber spectrum of the pressure fluctuations. A procedure is developed here to obtain the frequency-wavenumber spectrum due to fully developed turbulent flow. The data analysis procedures developed in this study to analyze the pressure fluctuations provide a good means to determine the frequency-wavenumber spectrum and represent this data in a clear form. Frequency-wavenumber spectra have been obtained for simulated pressure data. In the experimental system designed to collect turbulent pressure data, it was determined that a recessed transducer configuration cannot be used in water pipe flow turbulent pressure fluctuation studies because of the enhanced turbulence created by the upstream holes. Therefore, flush mounted transducers are required.

Show moreThe complex dynamics of the oceans are only beginning to be understood. There is a wide range of dynamic scales in the ocean from the Gulf Stream, with scales as large as the ocean itself, to the microstructure scales of turbulent dissipation. The program of work presented in this dissertation involves the implementation of a turbulence measurement package on board a recently developed small autonomous underwater vehicle (AUV), as well as the design of an optimized AUV platform and the development of new oceanographic sensors for measurement of micro-structure velocity. Attention is focused on ensuring that the platform is sufficiently quiet since small-scale, low level measurements are easily contaminated by the measurement process, structural vibrations, rigid-body motions and electrical interference; particularly so with the requisite machinery of a self-propelled AUV. Successful measurement entails making suitable modification to the AUV and its mode of operation. In addition to optimization of the measurement platform, consideration is given here to the optimization of the sensors for flow measurement using an AUV. Included in the research are laboratory tests of the new probes and a successful mission in making high quality measurements of ocean turbulence. Modern adaptation of the well-known Pitot tube shows promise in being less sensitive to vehicle self motion as well as yielding a greater spectral range, thereby facilitating more accurate measurement. Comparisons with shear probes and hot film probes, conducted in an axisymmetric water jet and in a wind tunnel, suggest that the pressure probe, developed as part of the work presented here, resolves the dissipation scales more fully than the shear probe. Additionally, the pressure probe does not suffer from the spectral distortion of the signal observed in measurements using a shear probe. In addition to measurement of velocity microstructure, consideration is given to the implementation of modern signal processing hardware in designing a method for the direct measurement of density microstructure. This basic property of the ocean has never before been measured directly. Results, obtained off the Florida coast in 18 meter deep water with the Ocean Explorer AUV; Cook, reveal a complex mixing event. Simultaneous measurement of two components of the velocity microstructure and measurements with a CTD package are analyzed and the instantaneous rates of viscous dissipation of turbulent energy are calculated. The dissipation rate was not stationary and showed a gradient vertically with depth as well as horizontally. The AUV platform, modified for low vibration noise, allowed measurement of dissipation rates of O(10^-8 W/kg).

Show moreThe developing subsurface structure of a shallow sub-tropical water column during the passage of cold low-pressure atmospheric front is characterized through synoptic and in-situ observations during the passage of three separate fronts over South Florida. Subsurface distribution of current, salinity, temperature, density and dissipation rates were examined using an autonomous underwater vehicle (AUV), ship-based instruments, moored instruments and an Ocean Surface Current Radar (OSCR) as the fronts passed through the region. Airfoil shear probes mounted in a package on the nose of the AUV were used to measure the level and distribution of small-scale turbulence in the water column and to estimate the in-situ dissipation rate of turbulent kinetic energy. Prevailing meteorological conditions were determined from two NOAA C-MAN stations and, for two of the experiments, from a local Air Sea Interaction Spar buoy (ASIS). The first atmospheric front examined was in December 1998. A significant 10°C drop in air temperature was recorded. The AUV carried out several pre-programmed surveys over a 6-day period. A turbulent kinetic energy dissipation rates of O(10-6W/kg) were observed in the water column during the passage of the front. Fetch-limited, offshore, wind-induced surface and subsurface currents were identified during the passage of the front on April 9, 2000. As the winds increased in magnitude and shifted direction, a change in surface current was apparent in the OSCR observations. A bottom-mounted ADCP and an AUV-mounted ADCP both recorded distinct corresponding contributions to the subsurface current due to the winds. Clockwise rotation of the current profile in the water column, consistent with wind-generated currents, was observed. A third low-pressure cold front passed through the region on April 18 an 19, 2000. AUV surveys were carried out as the front passed over the region for 19 hours within a 24-hour period. Dissipation rates reached O(10 -6W/kg) during the period of the survey and decreased to O(10 -8W/kg) subsequently. The distribution of dissipation rate appeared to agree with the characteristic log law for wind-induced turbulence at the start of the passage of the front, but was significantly higher subsequently and more dependent on the combination of convective fluxes and wind stress.

Show moreWater supply managers often look for easily applied metrics to determine where water use can be curtailed. Unfortunately, the one-size-fits-all mentality comes with a price of failing to fully grasp the consequences decision-making based on such metrics. One issue that water supply regulator like to use is per capita water use. Per capital water use is often used to show where there is “wasted” water use, such as excessive irrigation. However such a metric may not be truly applicable depending on other economic factors. A heavily industrial area may add to apparent per capital use, but actually is an economic development activity. The focus of this project is to look at various water utilities and their per capital usage with the intent of discerning whether or not a better metric could be developed that consider the economic development activities of the region and water use.
