Show moreThe accurate prediction of risky driving behaviors or possible accident and injury involvement contains several benefits as even minor increases in detection may result in possible avoidance of accidents and loss of life. This study examined the relationship between both broad and narrow personality traits and risky driving behaviors and the role of the bandwidth-fidelity dilemma. Based on archival data, 680 adults from a community sample in the Pacific Northwest completed the 16 Personality Factor Questionnaire (16PF) and a daily behavior inventory of act frequencies. Results indicated that broad and narrow personality traits are equally predictive of risky driving behaviors, but there are some appreciable differences at the primary factor level. Previous research, implications, and limitations to this study are also discussed.

Show moreThis work is an experimental study of high subsonic jet impingement tone suppression. We begin by documenting the characteristics of the impingement tone for various Mach numbers and standoff (nozzle exit to ground plate) distances. The results revealed frequency staging and the presence of two types of impingement tones. A novel feature of our work is the use of four miniature high-frequency actuators known as powered resonance tubes that were located circumferentially around the main jet nozzle. The powered resonance tubes were capable of producing high amplitude acoustic excitation over a range of frequencies, up to 17.5 kHz. Our target excitation frequency range was about 3-5 times that of the natural flow instability. Using high-frequency excitation, tonal suppression levels as high as 20 dB and broadband suppression levels as high as 5-10 dB were obtained. The mass addition rate from the powered resonance tubes was of the order of 2% of the mass flow rate from the main jet. Mass flow reductions could be obtained under conditions when the powered resonance tube resonated strongly. Our results suggest that appropriately designed miniature powered resonance tube actuators have potential for use in flow control applications.

Show moreWe report the first measurement of charged kaon Bose–Einstein correlations produced by 600 GeV/c Σ−, π− and 540 GeV/c p beams in the SELEX experiment. The SELEX (E781) experiment at Fermilab is a fixed target three–stage magnetic spectrometer designed for study hadroproduction at high acceptance for forward interactions (xF ≥ 0.1). One–dimensional charged kaon correlation functions were obtained for all three beams and three pair transverse momentum ranges. The femtoscopic parameters for the radii and correlation strength of the kaon source were extracted. The fit results show the decrease of the emission source radii with the increase of the pair transverse momentum.

Show moreThe study was a retrospective repeated measures analysis of 108 youth (age 6-12) who took part in the 2008-2012 Camp STAR (Summer Treatment Program for ADHD and Related Disorders) Summer Treatment Program. Developed by William E. Pelham in 1980, the Summer Treatment Program (STP) is an intensive psychosocial intervention delivered to children ages 6-12 in natural settings through the medium of summer camp. A recognized evidence base for the STP has steadily developed and evolved leading to improved stabilization of ADHD associated issues and treatment satisfaction. The following investigation sought to address questions about the efficacy of the STP with respect to predicting treatment responses for a subgroup of ADHD youth presenting with complex clinical presentations of combined type ADHD. The study built on prior evaluations of predictor importance by utilizing socio-emotional measures from the daily behavioral data of the STP, as well as more typically used ADHD dimensional symptom severity measures to inform treatment fit. As anticipated, because the heterogeneity of the disorder suggests that response to treatment is multifaceted, no combination of predictor variables produced a regression equation model that significantly explained variance across all of the treatment outcome variables. After controlling for concurrent pharmacotherapy and age, the combined effects of pretreatment core ADHD symptom severity and social functioning measures were found to significantly explain variance in a criterion variable corresponding with camp objectives (e.g., developing social competencies and coping skills, decreased functioning; Overall STP Improvement Index), as well as positive and negative socio-emotional behaviors measured directly by the STP Point System at the end of the camp. Change in R2 statistics confirmed the study hypothesis in which, the pretreatment socio-emotional factor sets significantly improved the prediction of multiple treatment outcomes over and above DSM-IV ADHD symptom dimensions and control variables. Ten percent of unique variance when predicting informant ratings of improvement made while at camp, 4% unique variance when predicting positive social behavior at the conclusion of Camp STAR, and 2% unique variance when predicting negative social behavior at the conclusion of Camp STAR were among the results. Observed negative behaviors at baseline demonstrated predictive utility whereas results pertaining to hyperactivity/impulsivity and inattention symptom dimensions did not significantly influence behavior, and subsequently, revealed little about the observed variation in outcomes in this particular dataset. While each of the core DSM-IV symptom dimensions are known to be differently associated with a variety of domain specific impairments in the general population (Lahey, & Willcutt, 2010), the results from this study suggest that with ADHD subgroups featuring severe symptom and impairment profiles, the core symptom dimensions did not appear to be as differentially associated with functional impairment. In cases of severe combined type ADHD, decisions about treatment fit should be based more on the socio-emotional impact of symptoms rather than their mere presence. The findings underscore the value in identifying socio-emotional impairments for individuals diagnosed with severe and complicated ADHD as early as possible and to intervene with intensive modalities specifically aimed at developing skills and cognitive faculties that enhance abilities to maintain healthy relationships.

Show moreOutbreaks of E. coli O157:H7 infections have been a continuing food safety challenge for the produce industry. Previous studies showed that contamination that originated in the farm can spread during postharvest processing. The objective of this study was to examine the spread of E. coli O157:H7 during postharvest washing of contaminated lettuce and to determine factors affecting the efficacy of sanitizer use in preventing cross-contamination. A bench-scale washing system was established to simulate industry operations. This system was equipped with a submersible pump and instruments to measure wash water properties including pH, temperature, chlorine level, oxidation reduction potential (ORP), turbidity and total organic carbon (TOC). Fresh-cut romaine lettuce (8 or 20 g) inoculated with approximately 8 log CFU/ml of E. coli O157:H7 with green fluorescence protein (GFP) were added into 40 L of tap water or industry water together with uninoculated lettuce (800 or 2000 g). The wash procedure lasted for 2 minutes. Washing operations were performed at two temperatures (3°C and 20°C) combined with different levels of chlorine treatments (0, 5, 20 and 30 ppm). Smaller-scale (50 – 100 mL) washing experiments were performed separately to determine the effects of organic contents and solid contents on the efficacy of sanitizer. Without chlorine treatment, the spread of E. coli O157:H7 occurred in both tap water and industry water at both 20°C and 3°C. With 20 ppm chlorine, no E. coli O157:H7 was detected in either wash water or uninoculated lettuce after washing in tap water. In industry water, chlorine level at 30 ppm or above could prevent crosscontamination of E. coli O157:H7. Neither the lettuce load nor the wash water temperature was proved to affect the efficacy of sanitizer. At 5 ppm of chlorine, increases in organic carbon (0% to 20%) led to the drop of free chlorine which resulted in a decrease in the microbial reduction from 2.51 to 0.01 log CFU/g. Increases in solid contents (0 g/L to 20 g/L) also caused a decrease in the microbial reduction from 2.52 to 1.17 log CFU/g but it did not change the free chlorine concentration. The utility of ORP as a measure of the antimicrobial efficiency of wash water was evaluated. ORP readings increased with increasing chlorine levels but reached a plateau and failed to correlate with the concentration of chlorine at chlorine levels > 20 ppm.

Show moreThis report provides a fast and reliable system for real-time face detection and recognition in complex backgrounds. Most current face recognition systems identify faces under constrained conditions, such as constant lighting condition, the same background. In the real world, people need to be recognized in complex backgrounds under different conditions, such as tilted head poses, various facial expressions, dark or strong lighting conditions. Meanwhile, because of large amounts of real-time applications for face recognition, such as intelligent robot, unmanned vehicle, security monitor, the fast face recognition rate needs to be satisfied for the real-time requirement. In this project, a fast and reliable system is designed to real-time detect and recognize faces under various conditions. Frames are obtained directly from VGA camera. Image preprocessing and face detection, collection, recognition are sequentially implemented on the frames. Local binary patterns and Haar features are used for face detection and eye detection. Local binary pattern encodes every pixel of the image for texture extraction, which is several times faster than Haar feature detection. Adaptive boosting algorithm is used for selecting the best weak classifiers and cascading method divides the extracted best classifiers into several stages to enhance detection rate. Affine transformation is implemented to unify the size of detected facial images and align two eyes to the desired position for improving recognition accuracy. 33 Gaussian filter is designed to remove noises of the pre-processed facial images. Principal component analysis (PCA) is used for face recognition, which is fast to identify high-dimensional faces with few principal components.

Show moreThis dissertation studies the problem of approximating functions of d variables in a separable Banach space Fd. In particular we are interested in convergence and tractability results in the worst case setting and in the average case setting. The symmetric positive definite kernel in both settings is of a product form Kd(x, t) := d =1 1 − α2 + α2 Kγ (x , t ) for all x, t ∈ Rd. The kernel Kd generalizes the anisotropic Gaussian kernel, whose tractability properties have been established in the literature. For a fixed d, we study rates of convergence, which indicate how quickly approximation errors decay. Since rates of convergence can deteriorate quickly as d increases, it is desirable to have dimension-independent convergence rates, which corresponds to the concept of strong polynomial tractability. We present sufficient conditions on {α }∞ =1 and {γ }∞ =1 under which strong polynomial tractability holds for function approximation problems in Fd. Numerical examples are presented to support the theory and guaranteed automatic algorithms are provided to solve the function approximation problem in a straightforward and efficient way. viii

Show morePedicularis rex is a hemiparasitic plant from the Orobanchaceae family. Hemiparasites, also called semiparasites, are partly dependent on their host and, while they steal nutrients and other metabolites like other parasites, they have retained their photosynthesis ability. To better understand the hemiparasitic lifestyle of Pedicularis rex and what remains of its photosynthetic capability, we have determined the complete sequence of its plastid chromosome. The chloroplast genome of Pedicularis rex is 153,650 base pairs-long and exhibits a typical quadripartite structure with a large single copy (LSC) region and a small single copy (SSC) region separated by two inverted repeats (IR). A total of 79 unique protein-coding genes, including 9 pseudogenes, 30 tRNA- and 4 rRNA-encoding genes were retained in the plastid genome. Compared to the plastome of its close non-parasitic relative Lindenbergia philippensis, only one protein-coding gene and one intron are missing from P. rex but many genes show signs of pseudogenization. Pseudogenization in the P. rex plastid genome was found to be mainly caused by single site insertions, deletions or substitutions. The overall high level of homology between the P. rex and L. philippensis plastomes may explain why P. rex shows weak host dependence. However, how P. rex maintains its photosynthetic capability despite featuring a number of potentially dysfunctional pseudogenes involved in photosynthesis is unclear, and the minimal set of genes that is required for hemiparasitic plants to keep their autotrophic lifestyle is still unknown.
