Show moreThis thesis investigates the effect of feature descriptor selection on pedestrian detection process. Pedestrian detection, the problem of recognizing, locating and tracking humans in videos has become a challenging task in computer vision area. Video surveillance and advanced driver assistance systems (ADAS) are few appli- cations of pedestrian detection. At the very rst stage of the pedestrian detection system, feature descriptors are created to describe the texture, shape and color in- formation of the pedestrian candidate. These extracted features, acts as an input to develop and test a pedestrian classi er Feature descriptor techniques su er from di erent kinds of problems such as illumination variation of the dataset, pedestrian pose di erences and noise in the region of interest (ROI). To overcome the problem of illumination change, depth maps, can be exploited due to their robustness under various illuminations. Considering real-time nature of the targeted applications, another important challenge for the feature descriptor technique is the computational complexity and also the resulting dimension of the feature space. In the initial part of this thesis, several feature descriptor techniques are ex-plored. In the primary part of this thesis work, two critical stages of pedestrian detec- tion are improved, depth map computation stage and the feature descriptor creation stage. Two novel fast techniques to compute depth maps are proposed for the depth- map computation stage; three newly proposed new descriptors are proposed which work on depth channel or a combination of depth and color to adaptively overcome the illumination variation problem while still maintaining low dimensional feature space. These methods are found to outperform existing state-of-the-art descriptors and with exceptionally low computational complexity.

Show moreCancer is a common disease that increases in prevalence with age; it predominantly affects individuals over the age of 55. Cancer can be associated with a number of health complications due to the disease itself and/or its treatments such as higher risk of infection, anemia, fatigue, and cognitive dysfunction. Risks of developing these complications increase with age. Despite the increased vulnerability among older individuals, the existing literature and clinical trials show a disproportionately low enrollment rate for this population. This study aimed to provide to a mechanism-based understanding of cognitive impairment in older patients with hematologic malignancy who were scheduled to undergo hematopoietic stem cell transplantation (HSCT). Emerging evidence suggests that a significant portion of older persons with cancer demonstrate cognitive impairment prior to HSCT, and that cognitive deficits prior to HSCT are related to post-transplant complications. Hence, the goals of the study were to characterize cognitive impairment in older cancer patients prior to HSCT, and to examine the relations between cognitive impairment, depression, and inflammation. Sixty-one patients with hematologic malignancy participated in the current study and were administered a comprehensive neuropsychological assessment. Results showed that 50% of the sample was impaired on verbal memory. Correlation analyses revealed a significant association between depression and attention, with inflammation found to be a non-significant mediator. Possible alternative explanations with implications for future research and limitations of the study were discussed.

Show moreDetecting humans in images or video sequences is a challenging task owing to their variable appearance and the wide range of poses that they can adopt. The first and most important factor in achieving satisfactory detection result is robust feature set that allows the human form to be discriminated clearly, even in cluttered background under difficult illumination. Many researchers endeavored to find a robust and light descriptor for human body for over twenty years. Some of them have presented enlightening approaches and promising performance, such as histogram of oriented gradients [1], purposed in 2006 and speeded fast robust feature [2] purposed in 2008 are both outstanding holistic features that give a nice description of pedestrian. Recently a rising trend in part-based approaches pedestrian classification aims to deal with occlusion occasions happen frequently in real world urban street scenarios. By dividing the pedestrian’s body image into several parts relaxes the detector’s emphasis on the whole pedestrian body. Even when part of pedestrian’s body cannot be seen in the image, the rest part of the body will still contribute to the classification.

Show moreLight olefins, e.g., ethene and propene, are important building blocks of chemical industry for the production of fuels, polymers, lubricants and other fine chemicals. Due to the rapidly increasing production of shale gas, conversion of small alkanes in the shale gas, e.g., ethane and propane, to their corresponding olefins via alkane dehydrogenation could be an important industrial process. This thesis has focused on exploring the novel single site heterogeneous catalysts for selective alkane dehydrogenation and investigating the general principles of rational catalyst design to achieve a better performing (e.g., more active, more stable, highly selective) dehydrogenation catalyst. Based on the observed reactivity of ZnO for olefin hydrogenation and activity of Zn-ZSM-5 catalysts for alkane activation, catalytic properties of isolated Zn2+ were first explored for propane dehydrogenation. The 3-coordinate Zn in single site Zn/SiO2 catalyst was demonstrated to be the catalytically active species that was highly selective for the generation of propene by propane dehydrogenation. DFT calculations revealed that slow β-hydride elimination of alkyl intermediates limited the overall activity of single site Zn/SiO2 catalyst. Thus, single site Co/SiO2 was also prepared in order to take the advantage of fast β-hydride elimination. The higher activity of single site Co/SiO2 emphasized the potential of transition metals for alkane dehydrogenation, and propane dehydrogenation reactivity of transition metals was further explored by investigating single site Fe/SiO2 catalyst. By comparing with metallic Fe nanoparticles and bulk phase Fe oxides catalysts, the 3-coordinate single site Fe2+ was also suggested to be the catalytically active species for selective propane dehydrogenation. However, the catalytic activity of single site Fe/SiO2 catalyst was lower than that of Zn/SiO2. Such result suggested heterolytic cleavage of C-H bonds was slow for transition metals, e.g., Co and Fe, due to their weak Lewis acidity, and it may mitigate the advantages gained in rapid β-hydride elimination. An exploration of ligand effects for improving heterolytic cleavage over single site heterogeneous catalysts was performed. The strength of metal oxygen bond governed by ligand electron donating effects and ligand basicity were found to be the critical chemical descriptors for a facile heterolytic cleavage. Those observed principles of ligand effects would lead to a new strategy of rational catalyst design for a superior dehydrogenation catalyst.

Show moreIn this thesis, we obtain several algorithms for problems related to matroids, a structure that generalizes the concept of linear independence in a vector space and an acyclic subgraph structure in a graph. Matroids have been widely applied in combinatorial optimization, graph theory, coding theory and so forth. Specifically, our results include: In this thesis, we present a constant-competitive online algorithm of the matroid secretary problem for the partition matroids without information of the partition and for the paving matroids. We also introduce the multi-objective matroid secretary problem that extends the matroid secretary problem, in which the weight function is a k-vector w = [w1, · · · , wk]. We show a constant competitive algorithm of the multiobjective matroid secretary problem for the uniform matroids and for the paving matroids. Since bases of a matroid generalize many important combinatorial structures, many counting problems can be expressed as a problem that counts the number of bases of a matroid. An efficient approximate counting algorithm can be designed provided that a rapidly-mixing Markov chain that samples bases of a matroid can be constructed. Let Φ(G) be the conductance of the base-exchange graph G. Matroid- Expansion Conjecture (1989, Mihai and Vazirani) states that Φ(G) ≥ 1 for any base-exchange graph G of a matroid, which implies an FPRAS (fully-polynomial randomized approximation scheme) for counting the number of bases of a matroid. We use λ2, the second smallest eigenvalue of L, the discrete Laplacian matrix of G, to prove the Matroid-Expansion Conjecture for any paving matroid, for any balanced matroid, and for the direct sum of a paving matroid with a balanced matroid. A maximum linear matroid parity set is called a basic matroid parity set, if its size is the rank of the matroid. We show that determining the existence of a common base (basic matroid parity set) for linear matroid intersection (linear matroid parity) is in NC2, provided that there are polynomial number of common bases (basic matroid parity sets). For graphic matroids, we show that finding a common base for matroid intersection is in NC2, if the number of common bases is polynomial bounded. We also give a new RNC2 algorithm that finds a common base for graphic matroid intersection. Finally, we prove that if there is a black-box NC algorithm for PIT (Polynomial Identity Testing), then there is an NC algorithm to determine the existence of a common base (basic matroid parity set) for linear matroid intersection (linear matroid parity).

Show moreIn this paper, we consider the boundary integral equation (BIE) corresponding to the Brinkmans equation. We compute the velocities of the interacting particles when the point-wise forces acting on them are known. We assume a ctitious ow point inside the bead and eliminate the double-layer in the BIE. This BIE is now numerically solved by covering the surface of the bead by two overlapping patches and de ning their partition of unity. We then discuss the e ect of the overlapping of the patches on the results. We develop a second-order accurate numerical method for the BIE. ix

Show moreFresh-cut vegetables are no longer considered low risk due to their association with an increasing number of E. coli O157:H7 outbreaks. E. coli O157:H7 contamination in fresh produce originated on farm can spread during postharvest washing. Industry and government guidelines have suggested the use of chemical disinfectants such as sodium hypochlorite in wash water to prevent microbial cross-contamination and have recommended that wash water disinfectants be monitored. However, specific standards regarding the levels of chlorine needed have yet to be established. The goal of this study was to determine the minimal effective level of chlorine needed to prevent E.coli O157:H7 cross-contamination during post-harvest washing of fresh-cut lettuce with wash water containing different levels of organic load and to evaluate the way to monitor the organic load in wash water by correlating measurements of Total Organic Carbon (TOC) with turbidity measurements. Eight grams of cut romaine lettuce inoculated with 8 log cfu/g of E. coli O157:H7 were washed with 800 g of uninoculated lettuce in 40 L of sterile tap water at 3℃ for 2 min. Washing trials were performed in water with different levels of organic load (with the addition of 0, 3, 6, 12, or 30 g of lettuce juice powder) and at different levels of chlorine treatment (0 - 40 ppm of sodium hypochlorite). The degree of cross-contamination was determined by measuring the presence of E. coli O157:H7 in the wash water and uninoculated lettuce after washing. Wash water samples were also analyzed for total/free chlorine, turbidity, and TOC. In the absence of chlorine, E. coli O157:H7 transfer occurred at all levels of organic load and resulted in the contamination of wash water and uninoculated lettuce at levels of 3.61 ± 0.13 log cfu/ml and 3.34 ± 0.23 log cfu/g, respectively. Without the addition of lettuce juice powder, cross-contamination was prevented in wash water containing 5 ppm of sodium hypochlorite. With the addition of 3 g of lettuce juice powder, transfer of E. coli O157:H7 was observed when the washing run was conducted with 5 ppm of sodium hypochlorite but was prevented when the level of sodium hypochlorite was raised to 10 ppm. With the addition of 30 g of lettuce powder, 40 ppm of sodium hypochlorite was needed to prevent cross-contamination. It was difficult to have an accurate determination of the residual free chlorine level as it continued to decrease during the washing run. Measurements of the organic load of wash water are needed to determine the effective level of sanitizer required to prevent microbial cross-contamination during postharvest washing of fresh-cut produce. TOC is a good indicator of organic load in wash water, but it took hours to get results. Turbidity measurement only takes minutes and it correlated well with TOC, indicating that turbidity has the potential to indicate the organic load in wash water.

Show moreNowadays, State transportation agencies have developed management systems as analytical tools to improve roadway safety. Management systems dealing with traffic safety hardware including traffic signs, signals, lighting, pavement markings, guardrails, barriers, and crash cushions have been identified as an important and non-separable part of safety management. As statistics shown, approximately 42,000 deaths on American roads due to vehicle crashes with one of the main causes being in lack of adequately performed safety hardware. It is easily realized that along the time the performance of traffic safety hardware decreases. State transportation agencies have spent millions of dollars on maintenance and replacement of safety hardware in each year. However, most of the agencies have not developed robust methodologies to assess impacts of traffic safety hardware on safety performance and optimize safety hardware investments. This study began with a literature review of safety performance functions and useful service lives of different types of safety hardware. Based on findings of the literature review and case studies conducted nationwide, this research proposes a new risk-based methodology for computing the safety index that assesses impacts of safety hardware conditions on vehicle crashes. The methodology is applied to a computational study by using 5- year data from 2002 to 2006 on 193 highway segments in Ozaukee County, Wisconsin. The results are compared with Empirical Bayesian adjusted crash estimates via statistical tests in order to validate the proposed methodology. Finally, it discusses future directions for continuing refinements of the proposed methodology.

Show moreThis thesis proposes a multi-layer strategy and an abstract map method to achieve an integrated planning of public fast-charging stations to charge certain number of lightduty battery electric vehicles in a given geographic region under its existing environment, aiming to improve application of electric vehicle in the studied region and finally enhance social welfare in a long term by optimally locating public fast-charging stations and assigning their installed capacities to maximize the possibility of effectively charging battery electric vehicles, as well as to minimize the infrastructure cost and mitigate possible negative impacts on the transportation system and the electric power system. In the first layer of this multi-layer strategy, the conditions of the transportation system are considered, analyzed and mathematically modeled, while in the second layer, based on the former layer, the conditions of the electric power system are incorporated. Then in the third layer, an integrated planning of public fast-charging stations is achieved by combining both the transportation system's and the electric power system's conditions. From the first to the last layer, a case is studied in each layer to test the idea, method and also the mathematical model which is built by the MILP method. These works are based on an abstract road network map which is rooted in the actual map of a representative geographic region. After the optimal results based on the abstract map are obtained, they will be mapped back to the actual map of the representative geographic region. Therefore, the ideas, methods and solutions studied in this thesis aiming to achieve an integrated planning of public fast-charging stations to charge battery electric vehicles are able to be applied in practice.
