Digital Acoustic Tracking Analysis Program, George H. Ford Apr 1981

Digital Acoustic Tracking Analysis Program, George H. Ford

Retrospective Theses and Dissertations

The purpose of this report is to investigate the processing of tracking data for acoustic targets. The programs developed for two- and three- dimensional space calculate the target's position via "hyperbolic-fix" navigation (geometric) considerations using the Newton-Raphson algorithm. The computer programs and the tracking solution approach contained herein is based on knowledge of only the sensors' locations and the relative time-difference at which a target's referenced, singular, acoustic pressure wavefronts are received at the sensors. Omnidirectional sensors are found to be sufficient for the two-dimensional space tracking problem. However, it is found that the three-space problem required usage of directional …

The Influence Of Confidentiality Conditions On The Amount Of Self Disclosure Of The Early Adolescent, Bella Kobocow Apr 1981

The Influence Of Confidentiality Conditions On The Amount Of Self Disclosure Of The Early Adolescent, Bella Kobocow

Retrospective Theses and Dissertations

While the importance of confidentiality in eliciting sensitive information in psychotherapy is generally assumed, there has been little experimental testing of this hypothesis. Therapists are understandably reluctant to manipulate conditions of confidentiality in a therapy situation, since such manipulation may adversely affect the progress of the client. In view of this circumstance, analogue experiments are an alternative in producing empirical data. The current study in an analogue. Forty-five male and forty-five female subjects were orally administered the same structured interview by a female experimenter. Interview questions were derived from existing standard personality and clinical assessment instruments, and school regulations and …

Involvement In Leisure Activities By Mental Health Center Clients And Non-Clients, David H. Roby Apr 1981

Involvement In Leisure Activities By Mental Health Center Clients And Non-Clients, David H. Roby

Retrospective Theses and Dissertations

A survey on the level and frequency of leisure activity in individuals getting clinical aid was compared with that of individuals not presently contemplating or receiving such help. The subjects, 26 females and 24 males in each group, responded to a questionnaire which requested information regarding demographics, and the rate (days per week), and duration (minutes per day), or participation in selected leisure activities. As was expected, based on Galsser's concept of Positive Addiction, the nonclinical group showed significantly more involvement in activities rated as possible Positive Addictions. No significant difference was found between groups on absolute numbers of leisure …

A Model For Assessing The Economic And Energy Savings Implications Of Cogeneration With Steam Turbines In Citrus Processing Plants, Harold L. Carpenter Apr 1981

A Model For Assessing The Economic And Energy Savings Implications Of Cogeneration With Steam Turbines In Citrus Processing Plants, Harold L. Carpenter

Retrospective Theses and Dissertations

A cogeneration system using a noncondensing steam turbine to simultaneously provide electricity and process steam to a citrus plant was modeled in order to assess the source energy savings and the economic implications with the employment of this type system under conditions of time varying plant energy demand. Average monthly energy demand data from on citrus plant was analyzed. It was determined that the important parameter, in addition to a minimum demand level, for assessing economic acceptability is the demand thermal to electric ratio. One set of steam conditions will not necessarily provide the maximum source energy savings and at …

Seasonal Periodicity Of Periphytic Algae In Relation To Water Quality In Three Florida Experimental Ponds, Michael J. Gilbrook Apr 1981

Seasonal Periodicity Of Periphytic Algae In Relation To Water Quality In Three Florida Experimental Ponds, Michael J. Gilbrook

Retrospective Theses and Dissertations

Periphytic algae biomass, periphyton taxonomic composition and water quality were monitored from October, 1978 through October, 1979 in three experimental ponds on the University of Central Florida campus, Orlando, Florida. Differences in the abundance and seasonal periodicity of phytoplankton in the ponds presumably arose from intrinsic differences in the nature of the pond sediments. Ceramic tile and pressboard wood artificial substrates were sampled at two-month intervals to provide estimates of periphyton biomass and productivity; there was no significant difference in algal biomass on wood and tile substrates. Algal productivity on continuous-immersion (cumulative) substrates which supported a large accumulation of periphyton …

An Experimental Study Of Dispersal Of The Cotton Rat, Sigmodon Hispidus, Stephen R. Stafford Apr 1981

An Experimental Study Of Dispersal Of The Cotton Rat, Sigmodon Hispidus, Stephen R. Stafford

Retrospective Theses and Dissertations

Dispersal of cotton rats was examined over an annual cycle of abundance by removal trapping in pine flatwoods. All cotton rats live-trapped at biweekly intervals on two 0.49 ha grids were removed, whereas rats on an adjacent control grid were tagged an released alive on site. The null hypothesis was that dispersing cotton rats would represent a random sample of sex and weight (age) classes from source populations, e.g. the control grid. Likewise, it was assumed that dispersal rates would be proportional to numerical changes in abundance on the control grid. Dispersing animals were clearly most prevalent on the removal …

Zooplankton Abundance And Diversity In Spring Lake, Florida, 1973-1976, Barry D. Billets Apr 1981

Zooplankton Abundance And Diversity In Spring Lake, Florida, 1973-1976, Barry D. Billets

Retrospective Theses and Dissertations

Seasonal variation in zooplanton abundance and diversity in Spring Lake, Florida was studies between 1973 - 1976. This clear, sand bottom lake is considered among the most oligotrophic in central Florida. Sixty rotifer species, sixteen cladoceran species, and seven copepod species were collected during the three year study. Annual mean zooplanton abundances ranged between 70 individuals/l and 80 individuals/l. Rotifers were more abundant than either cladocerans or adult copepods. Rotifers and immature crustaceans comprised nearly 75% of the annual mean zooplankton abundance. There was no significant difference (P < 0.05) between years for the annual mean abundance of zooplankton. The monthly mean abundance of cladocerans and adult copepods was generally less than 5 individuals/l. The greater abundance of rotifers in comparison to other zooplankton was mainly responsible for the variation in the values of the Shannon and Simpson Indices. The monthly mean Shannon Index was usually between 3.0 and 4.0. Seasonal differences in zooplankton abundance were apparently due to water temperature and specific conductivity for the 1974 - 1975 and 1975 - 1976 study years. Shannon diversity was significantly correlated with dissolved oxygen for the 1973 - 1974 and 1974 - 1975 study years.
