Show moreIn a distributed detection system, several geographically dispersed local sensors observe the same environment and transmit a condensed version of their observations to a fusion center. The fusion center then decides the presence or the absence of a target based on the information received from the sensors. The performances of several distributed detection rules are investigated. We study the asymptotic (as the number of sensors N $\to$ $\infty$) performance of the system when the fusion rule is a "k out of N" rule. With i.i.d. observations at the sensors and k out of N rule with fixed and finite k (or fixed and finite (N-k)) a necessary and sufficient condition, for vanishingly small probability of miss at a fixed probability of false alarm at the fusion center, is derived. The asymptotic performance of a k out of N rule is also studied for the case of correlated Gaussian observations., The effect of correlation on the performance of a distributed detection system is studied for a small number of sensors. The local sensor tests are assumed to be identical and the joint distribution of the observations at the sensors symmetric. It is shown in this case that the joint distribution of the sensor decisions, and therefore, the fusion center rule must be a symmetric function of the local decisions. A numerical performance study for the detection of a constant signal in correlated Gaussian or Laplacian noise shows that system performance deteriorates with increasing correlations. Furthermore, the OR combining rule, although relatively insensitive to changes in correlation coefficient, is inferior to the AND and MAJORITY LOGIC rules., We propose and analyze the performance of a multilevel quantization and fusion scheme that is useful in detecting unknown signals in noise. Numerical performance study shows that the scheme is robust with respect to changes in the signal levels at the sensors under the signal present hypothesis.

Show moreThis research is the array processing help wireless communication techniques to increase the signal accuracy. This technique has an important part of prevalent applications. The wireless communication system, radar, and sonar. Beamforming is one of methods in array processing that filters signals based on their capture time at each element in an array of antennas spatially. Numerous studies in adaptive array processing have been proposed in the last several decades, which are divided in two parts. The first one related to non-adaptive beamforming techniques and the next one related to digitally adaptive Beamforming methods. The trade-off between computational complexity and performance make them different. In this thesis, we concentrate on the expansion of array processing algorithms in both non-adaptive and adaptive ones with application of beamforming in 4G mobile antenna and radar systems. The conventional and generalized side-lobe canceller (GSC) structures beamforming algorithms were employed with a phase array antenna that changed the phase of arrivals in array antenna with common phased array structure antennas. An eight-element uniform linear array (ULA), consisting of di-pole antennas, represented as the antenna array. An anechoic chamber measures the operation of beamforming algorithms performance. An extended modified Kaiser weighting function is proposed to make a semi-adaptive structure in phased array beamforming. This technique is extended to low complexity functions like hyperbolic cosine and exponential functions. Furthermore, these algorithms are used in GSC beamforming. The side-lobe levels were so lower than other algorithms in conventional beamforming around -10 dB. On the other hand, a uniform linear arrays for smart antenna purposes designed to utilize in implementing and testing the proposed algorithms. In this thesis, performance of smart antenna with rectangular aperture coupled microstrip linear array which experimental investigations carried out for obtaining X-band operation of rectangular microstrip antenna by using aperture coupled feeding technique. Frequency range set at approximately 8.6 to 10.9 GHz, by incorporating frequency range of the antenna resonates for single wideband with an impedance bandwidth of 23%. The enhancement of impedance bandwidth and gain does not affect the nature of broadside radiation characteristics. This thesis describes the design, operation, and realization of the beamforming such as Sidelobe level (SLL) control and null forming array antenna are examined with the prototype. An antenna radiation pattern beam maximum can be simultaneously placed towards the intended user or Signal of interest (SOl), and, ideally nulls can be positioned towards directions of interfering signals or signals not of interest (SNOIs). Finally, we focused on the adaptive digitally algorithms in compact antenna that faces with mutual coupling. The variable step-size normalized lease mean square (VS-NLMS) algorithm is implemented in beamforming. This algorithm utilizes continuous adaptation. The weights are attuned that the final weight vector to the most satisfied result. The gradient vector can be achieved by iterative beamforming algorithm from the available data. This algorithm is compared with LMS, NLMS, VSS-NLMS algorithms, it is determined that the VSS-NLMS algorithm is better performance to other algorithms. Finally, we introduced novel adaptive IP-NNLMS beamformer. This beamformer reaches to faster convergence and lower error floor than the previous adaptive beamformers even at low SNRs in presence of mutual coupling. The experimental results verified the simulation results that the proposed technique has better performance than other algorithms in various situations.

Show moreJuncus roemerianus, the black rush, has long been used in restoration projects in south Florida because of its unique ability to live in both freshwater and saltwater. In particular, it has been used as an indicator of salt-water incursion due to its differing physical forms in varying levels of salinity. When found in freshwater, it can reach heights over 2.1 meters, yet when found in hypersaline water, it becomes dwarfed and only 1 meter in height. Because of its dramatic differences in physical appearance due to salinity, it has provided an easy and fairly cheap method of determining an area’s localized salinity level. Most of Juncus roemerianus’s range in Florida lies around the coasts, which most models predict will experience significant changes due to sea level rise in the not so distant future. The purpose of this study is to determine whether the black rush can remain an environmental restoration indicator species in conditions influenced by sea level rise. This study will take place in the FAU Boca greenhouse and will target increased water levels and increased pH as the main conditions affected by sea level rise. If this study finds that increased water levels and pH do not significantly change the appearance of Juncus roemerianus in varying salinity, then this plant can confidently remain an indicator of salt-water incursion in the future. Conversely, if these conditions do change the appearance of Juncus roemerianus, then this plant may not remain an indicator species in South Florida in the future.

Show moreAs sea levels continue to rise, the projected damage that will ensue presents a great challenge for conservation and management of coastal ecosystems in Florida. Since Juncus roemerianus is a common marsh plant throughout Florida with unique growing characteristics that make it a popular restoration plant, this study implemented a 20 week greenhouse split plot experiment to examine the effects of sea level rise on J. roemerianus and ultimately determine its tolerance ranges to salinity and inundation in a high nutrient environment. Overall, salinity level and the interaction effect of salinity level and water level had the greatest effects on measured growth parameters including average mature height, maximum height, density, basal area, root length, and biomass. An inverse relationship between increasing salinity and the measured growth variables was observed with the greatest growth and survivability in 0 ppt water, survivability and reduced growth in 20 ppt water, survivability and little growth in 30 ppt water, and nearly complete senesce in 40 ppt water. This was the first laboratory study to determine the effect of 40 ppt water on J. roemerianus. Elevated water levels resulted in higher growth variables in the 20 ppt, 30 ppt, and 40 ppt treatments while inundated water levels produced higher growth variables in the 0 ppt treatment despite previous research finding inundation to have completely adverse effects on J. roemerianus. It is likely that the high nutrient environment provided for this study is the cause for this anomaly. The results of this study have major implications for the future of coastal ecosystems that are dominated by stands of J. roemerianus in South Florida and can be used in conjunction with studies on bordering marsh plants to predict shifts in the ecosystems of Florida that are responding to sea level rise scenarios.

Show moreHealth disparities among rural African Americans include disproportionately higher morbidity and mortality rates associated with cardiovascular disease. Interventions designed to decrease cardiovascular risk can potentially improve health outcomes among rural, underserved communities. The purpose of this study was to test the effect of a cardiovascular health promotion intervention among rural African Americans. An experimental study randomized by church clusters was done in two rural counties in northern Florida. A total of 229 participants, 114 in the intervention group and 115 in the control group, were recruited from twelve rural African American churches. The pretest-posttest design included instruments chosen to measure cardiovascular health habits and knowledge as well as changes in produce consumption, dietary fat intake, and exercise using the major components of the Integrated Model of Behavioral Prediction: intentions, norms, attitudes, and self-efficacy. Linear mixed model was the statistical test used to detect the program effects. Participants who received the intervention had significant increases in scores for the cardiovascular health habits (p < .01) and health knowledge (p < .01) variables compared with the control group. There were also significant group differences regarding intentions to increase produce consumption (p < .01) and reduce dietary fat intake (p < .01). The cardiovascular health program was associated with other statistically significant results including produce consumption attitudes (p = .01) and norms (p < .01), dietary fat attitudes (p = .04) and norms (p < .01), and exercise attitudes (p < .01). There were also significant results found for perceived behavioral control/self-efficacy regarding increasing produce consumption (p < .01), reducing dietary fat intake (p = .03), and increasing exercise (p = .01). Compared to the control group, the cardiovascular health promotion intervention was effective in fostering positive health effects for most of the variables measured. The findings supported the theoretical framework used for guiding the study, the Integrative Model of Behavioral Prediction Nurse-led health promotion interventions within church settings can be effective means for reducing overall cardiovascular risk and health disparities among rural African American populations.

ATBlast program is used to calculate the blast loads for known values of charge weight and stand off distance. An excel spreadsheet is generated to calculate ultimate resistance, equivalent elastic stiffness, equivalent elastic deflection, natural period of the beam, the maximum deflection, and the maximum rotation in the support for a simple span solid slab and T-Beam bridges. The allowable rotation could be taken as to two degrees. Naval Facility Engineering Command (NAVFAC) approach was adopted, where the inputs were material properties, span length, and area of reinforcement. The use of the Fiber Reinforced Polymer for increasing the capacity of an existing bridge is also presented in this study. Parametric studies were carried out to evaluate the performance of the solid slab and T-Beam bridges under the assumed blast load.

Show moreThe influence of voids on the moisture uptake of epoxy has been studied. Specimens with void contents from 0 to about 50% were prepared. Void geometry and content were analyzed using microscopy and density methods. Void containing dry samples were characterized by Differential Scanning Calorimetry and Dynamic-Mechanical Analysis which verified consistency of chemistry of the epoxy network. The moisture uptake of specimens immersed in distilled water at 40 °C was monitored. The rate of absorption and saturation moisture content increased with increasing void content. The moisture uptake of void-free and void containing specimens was non-Fickian. The Langmuir model provided good fits to the experimental results for specimens with low to medium void content, although the moisture uptake of the high void content specimens showed substantial deviations from the Langmuir diffusion model. The moisture diffusivity agreed reasonably with predications from the Maxwell inclusion model over a range of void contents from 0 to 50%. The state of sorbed water was examined using mass balance calculations and DSC analysis. Only 6-8% of the void volume is occupied by water at saturation. Absorbed water may be classified as free and bound water. For void-free specimens, only bound water was found. The medium and high void content specimens contained water in three states: free water, freezable bound water, and non-freezable bound water. The DSC results show that the proportions of free water and freezable bound water increase with increasing void content, while the content of non-freezable bound water decreased. Moisture induced swelling decreased with increasing void content. The swelling is attributed to the content of non-freezable bound water.

Show moreThis mixed methods sequential research study was performed to explore the role of identity in posttraumatic growth and psychological adjustment for adults with cancer. One hundred nineteen individuals participated in an online survey which included items from Brief COPE, Mini-Mental Adjustment to Cancer (Mini-MAC), Brief Illness Perception Questionnaire (BIPQ), Sense of Coherence Scale - 3 items (SOC-3), Posttraumatic Growth Inventory (PTGI), Illness Intrusiveness Ratings Scale (IIRS), and Centrality of Event Scale (CES). A two-step cluster analysis divided the sample into two clusters based on the integration of cancer into identity: High Cancer Identity Cluster (cancer identity scores above M) with strong cancer identity and Low Cancer Identity Cluster (scores below the M) with a weak or absent cancer identity. HCIC yielded positive and negative subgroups. A discriminant analysis revealed which variables are significant predictors of group membership: PTG factor New Possibilities (Wilks'l = .781, F (1, 119) = 32.834, p = .000), Psychological Adjustment factor Anxious Preoccupation (Wilks' l= .863, F (1, 119) = 18.612, p = .000), Illness Intrusiveness factor Intimate Relationships (Wilks' l= .794, F (1, 119) = 30.348, p = .000), and Illness Perception factor Perceived Life Impact of Cancer (Wilks' l= .783, F (1, 119) = 32.412, p = .000). From the sample, 17 individuals and spouses/partners were interviewed to obtain a deeper understanding of the lived experience of cancer. Qualitative themes of suffering, woundedness, and uncertainty were found. Narrative data corroborated the quantitative data and contributed depth to the analysis. A new Cancer Identity Process Model was offered in which assimilative and accommodative efforts are informed by identity structures., Performing Normalcy is an assimilative process in which stressful life events such as cancer activate automatic behaviors guided by existing identity structures with the goal of reg As dissonance grows over the inability to re-establish valued former identities, negative affect and intrusive rumination prevails. Individuals then utilize accommodative strategies in a process of Constructing Survivorship to either regain valuable aspect of former identities or to create equally valued new ones.

Show moreCreating a safety culture is the focus in the current healthcare environment. An inhouse, around-the-clock laborist service delivery model has been associated with positive outcomes, but little is known about the laborist structure’s contribution to the labor-anddelivery working environment. The purpose of this descriptive correlational study was to explore the effects of physician service delivery model on safety culture, nurse-physician collaboration, and nurses’ job satisfaction. An additional purpose was to examine associations between nurses’ perceptions of safety culture, nurse-physician collaboration, and job satisfaction. Ray’s (1981, 1989) Theory of Bureaucratic Caring and Homan’s (1974) Social Exchange Theory guided this study. A survey consisting of demographic questions, the Collaborative Practice Scale (Weiss & Davis, 1985), the Hospital Survey on Patient Safety Culture (Agency for Healthcare Research and Quality, 2015; HSOPSC), and the McCloskey and Mueller Satisfaction Scale (McCloskey & Mueller, 1990) was distributed to registered nurses (RNs) nationwide. The results indicated that nurses in facilities using the around-the-clock model had higher perceptions of nursephysician collaboration, but not of safety culture or job satisfaction in relation to the physician service-delivery model. Significant moderate-to-strong correlations between nurses’ perceptions of patient safety and job satisfaction, and a weak correlation between bedside nurses’ perceptions of nurse-physician collaboration and job satisfaction were demonstrated. Additional significant correlations were found between the instrument subscales. Control/responsibility in the MMSS scale was positively associated with both management support for patient safety, supervisors’ and managers’ expectations and actions promoting patient safety, and overall perceptions of safety in the HSOPSC scale. Praise and recognition in the MMSS scale were positively associated with supervisor/manager expectations and actions promoting patient safety in the HSOPSC scale. Further appraisal is needed to understand the mechanism by which the laborist model affects patient care and work environment. Recommendations for future research include replicating the study with a larger sample sizes in specific groups based on the role and scheduled shift, conducting the study in a single system or location to mitigate the effects of other variables; and exploring physicians’ perspectives on the variables being studied.

Despite these positive developments, the government was unable to contain the anarchy that overcame Ukraine in the years that followed the collapse of the Empire. Various military groups and bands of hooligans terrorized the Jews and other minority populations, with the pogrom violence peaking in 1919. Ironically, some forty per cent of the recorded anti-Jewish pogroms were perpetrated by troops ostensibly loyal to the same Ukrainian government that supported the Ministry of Jewish Affairs. This dissertation examines the development of the Ukrainian-Jewish political experiment and the reasons for its eventual failure.

Non-Anglophone voices in literature can lead to a better understanding of the intricate relationships shown by Ashley Dawson tying capitalism, slow violence, and uneven development to climate change. There is skepticism that science fiction (sf) in particular can properly present climate issues in the anthropocentric era that we live in today, but scholars such as Shelley Streeby argue against such perceptions.

Show moreNon-Anglophone voices in literature can lead to a better understanding of the intricate relationships shown by Ashley Dawson tying capitalism, slow violence, and uneven development to climate change. There is skepticism that science fiction (sf) in particular can properly present climate issues in the anthropocentric era that we live in today, but scholars such as Shelley Streeby argue against such perceptions. Science fiction writers that use magical realism, such as Ngugi wa Thiong’o and Nalo Hopkinson, as ecological sf have already accomplished the task of creating speculative works that fit in perfectly under the umbrella of “serious fictions.” These writers work from a non-Anglophone perspective or from a minority group within a Western society, allowing for different modes of thinking to play a part in these bigger discourses. Writers, educators, and other scholars need to reestablish humanity’s kinship with nature.

The magnitude of immune responses to vaccination is a critical factor in determining protection from diseases. We reported that nicotine disrupts the properties of DCs that are pivotal in the initiation of immune response to vaccines. Here we investigated whether TLR agonist(s) could overcome the effects of nicotine on human DC and DC-NK cross-talk essential for effector T cell generation. nicDC, nicDC-NK, and nicDC-NK-T cultures exposed to TLR agonists were evaluated for expression of...
Show moreThe magnitude of immune responses to vaccination is a critical factor in determining protection from diseases. We reported that nicotine disrupts the properties of DCs that are pivotal in the initiation of immune response to vaccines. Here we investigated whether TLR agonist(s) could overcome the effects of nicotine on human DC and DC-NK cross-talk essential for effector T cell generation. nicDC, nicDC-NK, and nicDC-NK-T cultures exposed to TLR agonists were evaluated for expression of costimulatory molecules, cytokines, and intracellular cytokine IFN-g using ELISA and flow cytometry. Our data shows that among the TLR agonists, TLR3 and TLR8/7 synergistically optimized nicDC maturation co-cultured NK cell activation. Importantly, similar to DC-NK, nicDC-NK treated with TLR3 and TLR8/7 and co-cultured with naïve T cells promoted a comparable number of effector T cells. Our data suggest that the addition of appropriate TLR agonist(s) to vaccine formulation could potentially improve the smokers’ immune response to vaccination.
