Show moreSanitizers have been widely used in controlling cross-contamination during fresh produce washing processes. It is important to identify different approaches for monitoring the efficacy of sanitizer washing. In this study, our objective was to determine the feasibility of indicator microorganisms in assessing the efficacy of chlorine and peroxyacetic acid (PAA) in fresh-cut produce washing. In inactivation experiments, the survivals of inoculated indicator microorganisms [total viable count (TVC), Enterobacteriaceae and total coliforms] and E. coli O157:H7 were determined after exposure to different concentrations of chlorine or PAA in water with added organic load (TOC~200 mg/l). In small-scale washing experiments, bacterial transfer from lettuce leaves inoculated with indicators or E. coli O157:H7 to wash water containing chlorine or PAA with/without organic matters was evaluated. In the inactivation study, higher log reduction was observed for Enterobacteriaceae and total coliforms than for E. coli O157:H7 after chlorine treatment at an initial concentration of 30 ppm. In the bacterial transfer study [a inoculated leaf (~5 log CFU) in 30 ml of wash water], without additional organic matter, approximately 3.5 log total CFU of all bacteria groups was transferred into wash water. Less than 1.5 log total CFU were detected for Enterobacteriaceae, total coliforms and E. coli O157:H7 in 1 ppm chlorine washing. With introduced organic matter, similar microbial loads of Enterobacteriaceae, total coliforms and E. coli O157:H7 were detected on washed leaves and in wash water with initial chlorine concentration of 1 ppm; when initial chlorine level increased to 10 ppm, less than 2 log total CFU of Enterobacteriaceae and total coliforms was detected while about 3 log total CFU of E. coli O157:H7 transferred to wash water, suggesting that chlorine at an initial concentration of 10 ppm could not prevent cross-contamination in the presence of organic load. The indicators showed different levels of survival and transfer from E. coli O157:H7 in this study and were unreliable to effectively monitor the behavior of the pathogen during chlorine wash in fresh produce processes. Enterobacteriaceae and total coliforms were more vulnerable to 40 ppm PAA treatment than E. coli O157:H7 in PAA inactivation experiments. No survival, except for TVC, was observed after 80 ppm of PAA inactivation. In the bacterial transfer study, 40 ppm PAA in wash water was found unable to prevent cross-contamination of indicators and E. coli O157:H7 from leaves to water. Further investigation is needed to compare the bacterial transfer levels of E. coli O157:H7 and the indicators at higher PAA levels.

Show moreThe batch scheduler is an important system software serving as the interface between users and HPC systems. Users submit their jobs via batch scheduling portal and the batch scheduler makes scheduling decision for each job based on its request for system resources and system availability. Jobs submitted to HPC systems are usually parallel applications and their lifecycle consists of multiple running phases, such as computation, communication and input/output data. Thus, the running of such parallel applications could involve various system resources, such as power, network bandwidth, I/O bandwidth, storage, etc. And most of these system resources are shared among concurrently running jobs. However, Today's batch schedulers do not take the contention and interference between jobs over these resources into consideration for making scheduling decisions, which has been identified as one of the major culprits for both the system and application performance variability. In this work, we propose a cooperative batch scheduling framework for HPC systems. The motivation of our work is to take important factors about jobs and the system, such as job power, job communication characteristics and network topology, for making orchestrated scheduling decisions to reduce the contention between concurrently running jobs and to alleviate the performance variability. Our contributions are the design and implementation of several coordinated scheduling models and algorithms for addressing some chronic issues in HPC systems. The proposed models and algorithms in this work have been evaluated by the means of simulation using workload traces and application communication traces collected from production HPC systems. Preliminary experimental results show that our models and algorithms can effectively improve the application and the system overall performance, HPC facilities' operation cost, and alleviate the performance variability caused by job interference.

Show moreThe scope of this study is focused on the applicability of the interval method to the reliability analysis of structures. The study includes using the traditional probability methods in several applications and comparing the results with the interval analysis. Accordingly, the interval arithmetic rules are applied in several examples and the results are compared with those from the traditional probability theory concepts. Specifically, the procedure for using the interval methods was applied to the development of the probability of failure for a simple structural member; and for a link in a network system. Through three simple examples, the research shows that the interval method offers comparable results with those from the traditional first-order reliability method. The procedure based on the interval method, however, may offer advantages, especially in cases where the uncertainties in various parameters describing the reliability of a system are large. In the presence of large uncertainties, the traditional methods of reliability analysis, based on the first order approximation, may lose their accuracy. In these cases, the interval method may offer a simple method yet with more accurate results.

Show moreThis study is focused on comparing the wild type and mutated versions of the Vitreoscilla hemoglobin gene (vgb). The purpose of this focus is to find out whether any of the vgb mutations provides an advantage regarding cell growth rate, as well as on the expression level of Vitreoscilla hemoglobin protein (VHb). A negative control Escherichia coli DH5α (E. coli DH5α) bearing no pUC plasmid, as well as seven E. coli DH5α strains bearing different pUC-based plasmids were tested in the experiments. Among these were one vector-only negative control (pUC18), one wild type positive control (pUC8:16, which carries wild type vgb) and five different types of pUC-bearing vgb mutants (pUC-vgb M1, M2, M3, M4 and pUC18-vgb M3). In order to compare cell growth rate among these strains, the growth rate assay was carried out under three different conditions: (1) Luria-Bertani (LB) medium, aerobic conditions; (2) Terrific Broth (TB) medium, low oxygen conditions; and (3) TB medium, microaerobic conditions. In addition, the carbon monoxide (CO) difference spectra assay was conducted to measure functioning VHb protein expression levels for the strains grown under aerobic conditions. In contrast to the results obtained by our Australian collaborators, our growth rate assay and CO difference spectra assay showed no growth advantage or higher expression level of functioning VHb protein due to any of the vgb mutations. For the further study of the vgb mutants, four different recombinant plasmids were constructed by cloning three types of mutated vgb (vgb M1, M3 and M4) as well as wild type vgb into the prokaryotic expression vector pUC8 with ampicillin (Amp) resistance. After being transformed into competent E. coli DH5α cell, these resulting xii strains, as well as the plasmid-free negative control (E. coli DH5α) and vector-only negative control (E. coli DH5α bearing plasmid pUC8) were tested by the CO difference spectra assay. Except strain E. coli DH5α [pUC8-vgb M3], which showed a slight increase in the VHb expression level, the strain bearing other mutated vgbs did not demonstrate any elevation in VHb protein expression level, compared to the positive control containing wild type vgb.

Show moreThe tumor suppressor gene, Bax, plays a critical role in tumor progression through regulating cell apoptosis. Mutations on the BAX gene often result in silencing its expression and the loss of pro-death ability. However, there is a unique Bax isoform, BaxΔ2, recently discovered in these Bax mutated cancer cells. BaxΔ2 isoform shows higher pro-apoptotic activity than Baxα. Unlike the parental Baxα, BaxΔ2 does not target mitochondria and forms aggregates in cytosol. There is a unique 10-amino-acid peptide in the N-terminus of BaxΔ2 protein possible function as a special signal. Two serines in this region are predicted as potential phosphorylation sites for regulation of the protein activity. To test this hypothesis, we mutated both serines (SS) into non-phosphorylatable alanines (AA) by site-directed mutagenesis approach. Both BaxΔ2 wild type (BaxΔ2-SS) and mutants (BaxΔ2-AA) were tagged with GFP, which allows us to monitor the protein expression and cellular localization in live cells. Here, we found that the distribution patterns of BaxΔ2-AA and BaxΔ2-SS were similar and appeared as aggregates in cytosol. BaxΔ2-AA mutant also possessed the similar pro-apoptotic activity with BaxΔ2-SS wild type. These results suggested that the two serines in BaxΔ2 unique oligopeptide might not play a critical role in BaxΔ2 localization and pro-death activity under the current ectopic expression conditions. Further study is needed to have better understanding of phosphorylation in contribution to unique behavior of BaxΔ2.

Show moreBecause of the increasing requirement of precision in region of 3-D map, we began to use LiDAR to establish a more accurate map. There still exist some problems although we have already made a great progress in this area. One of them, which I tried to process during my thesis study, is that we have two points source - Aerial LiDAR Data( Points gotten by Airplane ) and Vehicle LiDAR Data( Points gotten by Vehicle ) - while both of them have a different density and cannot be merged well. This process - Fusion-is kindly similar to registration, the difference is that the points we would like to merge are generated from different devices and have only few points pairs in the same region. For example, the Aerial LiDAR data has a higher points density in the roofs and ground, but lower in the walls. In the meanwhile, the Vehicle LiDAR data has a lot of points in the walls and ground region. It is beneficial to minimize the difference between these two point sets since the process is necessary for modeling, registration and so on. Therefore, my thesis is to minimize the difference between these two data sources, a procedure of Fusion. The main idea is to read the LiDAR data into data structure of Point Cloud, sample their density to the similar level, and select several corresponding special region pairs( we named these regions -chunks, e.g. Median strip and boundaries of road ) with sufficient interesting points to do fusion. Interesting points indicate the points with one and more special features among all points. And, the algorithm we used to implement the fusion is ICP( Iterative Closet Point Algorithm). Not similar to Registration of Point Cloud, research in the Fusion area is rare. Therefore, the existing algorithms are not well suitable in this project. I deduce some new algorithms during my research since the original ICP Algorithm cannot work well. Both Update Equation and Objective Function are modified. In this thesis, PCL( Point Cloud Library ) is mainly used to implement the basic function, such as nding the nearest points and sampling point cloud, and Eigen library to write the core functions( e.g. Modified Iterative Closest Point Alg ). I also use libLAS library to implement the IO operations and MeshLab to visualize the point cloud after modification.

Show moreThere continues to be significant growth in the development and use of speech–mediated devices and technology products; however, there is no evidence that non-native English speech is used in these devices, despite the fact that English is now spoken by more non-native speakers than native speakers, worldwide. This relative absence of non-native English speech in devices may be due in part to the costs associated with localizing speech devices, but it may also be attributable to the fact that not enough is known about user performance with accented speech in speech–mediated environments. In the absence of targeted research, developers may be relying on existing studies which focus on perception (impression) of accented speech, as a basis of decision-making. However, perception paints only part of the picture when it comes to understanding how and why people perform in certain ways and in certain environments. Three studies were conducted to answer the following questions: (1) What are the acoustic-phonetic characteristics of negatively- and positively-perceived accented speech? And how are these characteristics related to markers of intelligible speech? (2) How do participants perform on different types of accented-speech tasks? (3) What is the relationship between user perception of accented speech and user performance in response to accented speech? and; (4) How do participants perform on accented speech tasks of varying complexity? Arising out of this research, there are six recommendations for the use of accented speech in speech-mediated devices. Also, the findings of this study raise questions about inherent linguistic stereotypes which impact both our perceptions and our choices about xvi the accents we want to hear on our speech devices. A discussion about if and how these stereotypes can be altered and measured are included. Future research should examine the role of experienced non-native talkers in speech devices. Results of study one demonstrated that some experienced non-native talkers were positively-perceived by raters and may be good candidates for talkers in speech devices. A study like this would explicitly establish if listeners consistently make native vs. non-native distinctions in their preferences or if a prestige continuum emerges.

Show moreIndia’s huge and growing population is putting severe strain on all of the country’s natural resources. Most water sources are used on a domestic, industrial and agricultural basis. The quality of the water used is presumed to be the major problem that the people face, but the real problem is the quantity of water supplied. Quite a few organizations have been engaged with supplying drinking water to the community, but still not enough to address the needs of all the different sectors of the community, especially irrigation. In order to increase the availability of water to the people, it is necessary that the people have alternative means of supply of water, and a strong sense of the value of water.
