▼ Lyme disease, the most prevalent vector-borne disease in the United States, is caused by the spirochete <i>Borrelia burgdorferi</i> (Bb). After transmission via tick-bite, Bb remains within the skin for 12 to 48 hours before disseminating to numerous tissues. While Bb lacks several stimulatory cellular components typical of Gram-positive and Gram-negative bacteria, it produces many lipoproteins that potently elicit inflammatory responses via Toll-like receptor-2 (TLR2). Although TLR2-mediated responses are critical for controlling Bb numbers, the responding cells often fail to clear the infection, allowing the bacteria to disseminate and establish persistent infection. <i>In vitro</i> studies indicate that Bb directly activate professional phagocytes that can efficiently phagocytose and kill both opsonized and unopsonized Bb. However, Bb exhibit an ID50 of <50 organisms <i> in vivo,</i> indicating that the bacteria efficiently evade phagocyte killing and suggesting that traditional <i>in vitro</i> models are inadequate for accurately assessing the evasion mechanisms of these fastidious spirochetes. Thus, there is an urgent need to develop techniques that allow direct assessment of the interactions between Bb and skin-associated phagocytes within living susceptible hosts. We have developed a novel system to directly visualize the behaviors of infectious Bb strains expressing fluorescence markers <i>in situ</i> using confocal microscopy. This model allows the acquisition of four-dimensional data reflecting Bb motility and migration in the skin of anesthetized mice during the natural course of infection. Using these techniques, our data describes the <i>in vivo</i> kinetics of Bb dissemination and persistence within the skin. These studies should identify Bb evasion mechanisms that can be targeted for novel curative treatments for Lyme disease.

▼ Folate receptors (FRs) are over-expressed on many tumor cell surfaces compared to most normal tissues. Uptake of folic acid (FA) or FA conjugates into cells can occur by the FR-mediated endocytic pathway. We are attempting to use this pathway to achieve two goals: (1) Deliver FA conjugates selectively to tumor cell surfaces in preference to normal cells; and, (2) Enhance the entry of FA conjugates into tumor cells to a greater extent than by their non-transport-mediated pelmeation for which physicochemical barriers can sometimes limit the entry of drugs. Two methods have been developed to prepare pteroic acid, which is a key starting material for the syntheses of various types of FA conjugates. The first method represents the optimization of an enzymatic approach reported in the literature. The second method involves a new chemical treatment that we have shown to be generally useful for syntheses of several FA conjugates such as folate-paclitaxel (FA-PAC), folate-rhodamine dye (FA-RD), and folate-perfluorocarbon (FA-PFC) compounds. A FA-PAC conjugate was prepared to potentially increase PAC's selectivity for cancer cells versus healthy cells, and also to decrease PAC's multi-drug resistance (MDR) liability. Due to the strong fluorescence properties of rhodamine, a series of FA-RD conjugates was made to study the FA uptake transporter and the latter's release of ligands, as well as to clarify any observed selectivity demonstrated by the PAC series. A series of FA-F conjugates was prepared to determine their interactions with FRs and make them available for subsequent examination as potential ultrasound contrast agents using ultrasound imaging technology. Three kinds of human cancer cell lines are being used for assessment of these probe's preliminary biological properties: KB; HeLa; and CEM-7A cell lines. The KB cell line has highly over-expressed FRs and the HeLa cell line has moderately over-expressed FRs. Alternatively, the CEM-7A cell line has highly over-expressed reduced folic acid carriers (RFCs) instead of FRs. A control human cell line was additionally chosen for each type of FR and RFC cell line during these tests. The reason for including the CEM-7A cell line is to examine whether the FA conjugates will be recognized as FA only by FRs or also by RFCs which tend to be more ubiquitously expressed on normal cells. Anticancer activity of the FA-PAC analog is also being examined using these kinds of cell lines wherein growth inhibition (GI50's) will indicate which compounds are the most active. For the MDR study of PAC, the pair of MCF7 and NCI/ADR-RES human breast cancer cell lines will be used for the biological testing. MCF7 is a tumor cell line without MDR while the NCI/ADR-RES cell line has over-expressed Pgp which is directly related to the degree of MDR. MCF12A will be used as a control cell line for these latter studies.

▼ A linear accelerator manufactured by Elekta, equipped with a multi leaf collimation (MLC) system has been modelled using Monte Carlo simulations with the photon flattening filter removed. The purpose of this investigation was to show that more efficient and more accurate Intensity Modulated Radiation Therapy (IMRT) treatments can be delivered from a standard linear accelerator with the flattening filter removed from the beam. A range of simulations of 6 MV and 10 MV photon were studied and compared to a model of a standard accelerator which included the flattening filter for those beams. Measurements using a scanning water phantom were also performed after the flattening filter had been removed. We show here that with the flattening filter removed, an increase to the dose on the central axis by a factor of 2.35 and 4.18 is achieved for 6 MV and 10 MV photon beams respectively using a standard 10x 10cm2 field size. A comparison of the dose at points at the field edges led to the result that, removal of the flattening filter reduced the dose at these points by approximately 10% for the 6 MV beam over the clinical range of field sizes. A further consequence of removing the flattening filter was the softening of the photon energy spectrum leading to a steeper reduction in dose at depths greater than dmax. Also studied was the electron contamination brought about by the removal of the filter. To reduce this electron contamination and thus reduce the skin dose to the patient we consider the use of an electron scattering foil in the beam path. The electron scattering foil had very little effect on dmax. From simulations of a standard 6MV beam, a filter-free beam and a filter-free beam with electron scattering foil, we deduce that the proportion of electrons in the photon beam is 0.35%, 0.28% and 0.27%, consecutively. In short, higher dose rates will result in decreased treatment times and the reduced dose outside of the field is indicative of reducing the dose to the surrounding tissue. Electron contamination was found to be comparable with conventional IMRT treatments carried out with a flattening filter.

▼ Response to intervention (RTI) is an intervention framework introduced in the 2004 Individuals with Disability Educational Improvement Act (IDEIA), in conjunction with No Child Left Behind (NCLB). Even though RTI is mentioned in this legislation, at this time it is encouraged but not mandated (Pierangelo & Giuliani, 2008). Although many of the components of this framework have been a part of the education process, there is little research indicating this new initiative is effective (Wright, 2007). Little qualitative research exists in this area and even less in the area of pre-service preparation for teachers in RTI (Danielson, Doolittle, & Bradley, 2007). The major focus of this qualitative study was teacher perception of training and professional development received prior to implementing RTI. Three research questions were addressed. First, what are teacher perceptions about how they are prepared to understand and implement RTI before it officially begins in a school? Second, what types of training or professional development are provided prior to beginning the process and for how long? Third, do teachers perceive this training to provide sufficient information and support to begin the process? The targeted population was general education teachers, 10 of whom piloted the RTI framework in their buildings. The structured interviews were transcribed verbatim. Through an extensive analysis of the data, codes and themes became apparent. The data provided by the research participants indicated that the majority of teachers felt positive about the training they had received; however they felt they had not received enough training. The major focus of the training for many of the participants was the use of DIEBELS testing. Other themes emerged regarding leadership, special education involvement, general education responsibilities, and beliefs in RTI. Recommendations include a framework for the implementations of RTI.

▼ The aim of the present study was to use chitosan (CS) based microparticles (MPs) to treat critical sized bone defects in rat models. The advantage of MPs over scaffolds is that MPs can be easily injected into the defect site using minimally invasive technique. CS based MPs ionically cross-linked with sodium tri-polyphospahte (TPP) were fabricated using emulsification technique. We have optimized the cross-linking density that is required to give particles with spherical morphology in 1X batches (approximate yield: 110 g MPs) and scaled up the process to fabricate 4X batches (approximate yield: 400 g MPs). Scale up of the fabrication process was necessary to produce larger quantities of MPs from each batch. We have also used three other formulations to fabricate hybrid CS MPs by incorporating either 10%, 20% calcium phosphate (CaHPO4), or 10% calcium carbonate (CaCO3) to the optimized 4X batches. We have studied the attachment and proliferation of mesenchymal stem cells (MSCs) on these hybrid MPs. MSCs seeded on the hybrid MPs have shown good attachment and proliferation. MSCs seeded on the MPs showed differentiation towards osteoblasts as evident from the expression of alkaline phosphatase (ALP), osteocalcin (OC), and collagen I (COL I) on days 7, 14, 21, and 28. Finally, MSCs seeded CS MPs were evaluated for <i>in vivo</i> bone formation using a rat femur model. <i>In vivo</i> bone formation was examined using x-ray imaging, micro computed tomography (µ-CT), and histology at 4 and 8 weeks after the implantation. The <i>in vivo </i> studies showed that the group of rats that received the implant had better bone healing compared to the control groups. It is known that macrophages play an important role in wound healing. To test the appropriateness of macrophages in bone healing we have studied the expression of growth factors like transforming growth factor (TGF-β) and bone morphogenic proteins (BMPs) in macrophages. We have also co-cultured the macrophages and osteoblasts (OBs) on the hybrid MPs to look at the influence of macrophages on bone regeneration <i>in vitro</i>. Macrophages expressed TGF-β and BMPs when seeded on the MPs. Co-culture studies showed that the expression of ALP and COLLI was up regulated on day 7.

▼ This study investigated various state policies to determine their impact on the state share of instruction (SSI) funding to community colleges in the state of Ohio. To complete the policy analysis, the researcher utilized three policy analysis tools, defined by Gill and Saunders (2010) as iterative processes, intuition and judgment, and advice and opinion. The findings identify key policies that impacted the development and state funding of community colleges. Additionally, the researcher found access was the key policy driver during the time period of this study. The state of Ohio linked its state higher education budget to the policy of access by implementing and maintaining an enrollment-driven formula throughout the years of this study during which data were examined (1962-2009). In fiscal year 1998, Ohio added the Access Challenge, which provided funding to community colleges to help them keep tuition costs low, which again reflected and emphasized the State's policy to provide access to all citizens.

▼ As the prevalence of HIV/AIDS continues to reach pandemic proportions and medical advancements allow for persons to live longer with the disease, counselors should expect to work with clientele who present with HIV/AIDS. Persons with HIV/AIDS often present with unique mental health issues and diagnostic dilemmas. One of the most common mental health issues reported in persons with HIV/AIDS is that of depression. Research suggests that depressive symptoms are more common in persons with HIV/AIDS; however, depression in persons with HIV may be over-diagnosed and/or misdiagnosed as a result of the somatic features of HIV (Judd et al., 2005; Kalichman, Sikkema, & Somlai, 1995). The physical and physiological symptoms of HIV/AIDS often resemble typical symptoms of depression (Kalichman, Sikkema, & Somlai, 1995; Rabkin, Wagner, & Rabkin, 2002). As a result of depressive symptoms and HIV illness consisting of similar features, the literature both challenges and supports the belief that persons with HIV/AIDS are more likely to be depressed. Subsequently, it is suggested that when using depression rating tools with persons with HIV, one should focus on affective symptoms rather than somatic symptoms (Rabkin et al., 2002). The Beck Depression Inventory-II (BDI-II), which is the most widely used instrument for measuring depression in the mental health profession, has not been validated among persons with HIV/AIDS (Barroso & Sandelowski, 2001; Kalichman, Sikkema, & Somlai, 1995). Further, research suggests that specific items on depression rating tools, like the BDI-II, may be more indicative of HIV illness, such as central nervous system functioning or physical ailments, rather than depressive symptoms (Castellon et al., 2006). In order to determine if the Beck Depression Inventory-II is an effective tool in assessing depression in persons with HIV/AIDS, it may be useful to compare the BDI-II with other depression screening tools that are more widely used in persons with chronic illness such as HIV. In the current study, persons diagnosed with HIV who were receiving medical treatment for HIV management completed both the Beck Depression Inventory-II (BDI-II) and the Patient Health Questionnaire (PHQ-9). In addition, study participants were also invited to respond to open-ended items relating to depression and factors commonly associated with depression. Results indicated that there were no statistically significant difference between depression as indicated by the BDI-II and the PHQ-9. Limitations of the study and suggestions for future research are presented.

▼ The protein coding sequences of humans and of most mammals represent less than 2% of their genomes. The remaining 98% is made up of 5'- and 3'-untranslated regions of mRNAs (<2%), introns (∼30%), and intergenic regions (∼66%).These vast non-protein coding genomic areas, previously frequently referred to as "junk" DNA, contain numerous functional signals of various origin and purpose. The presence of functional information within these vast non-protein coding regions creates function dependent compositional variations. The traditional techniques for mining functional regions have focused mainly on comparative methods where strong sequence similarity of genomic regions between evolutionarily distant species, was deemed to be indicative of a fixation bias in order to maintain functional integrity. In this study we present a novel method of mining functional regions which range in length from 30 nucleotides to several thousands of nucleotides, which we call Mid-Range scale or Mid-Range Inhomogeneity (MRI / genomic MRI). The focus of this study is to demonstrate that at these mid-range scales, genomes of complex eukaryotes consist of a number of different nucleotide compositional patterns which are associated with unusual DNA conformations, RNA secondary structures and non-coding RNA. Some of these patterns are scarcely investigated and still await thorough exploration and recognition.

▼ <i>Streptococcus pneumonia</i> is a prevalent cause of disease and mortality worldwide. Pneumococcal disease includes pneumonia, otitis media, bacteremia and meningitis. Antibodies against the pneumococcal capsular polysaccharide are protective and aid in clearance of the bacteria. The phenotype of human anti-pneumococcal polysaccharide (PPS) B cells has not been well characterized. Immune-compromised individuals often respond poorly to the 23-valent purified pneumococcal polysaccharide vaccine (PPV) and are often deficient in IgM memory and switched memory IgM<sup>− </sup> cells. We hypothesized that the anti-PPS B cells which respond to PPV are IgM memory cells. To directly characterize anti-PPS B cells, fluorescently labeled PPS14 and PPS23F in conjunction with a FACSAria flow cytometer were used to detect and characterize PPS-specific B cells from healthy young adult volunteers pre- and post-vaccination with PPV. Post-vaccination PPS-specific B cells expressed a dominant IgM memory phenotype, CD27+IgM +, suggesting a key role of IgM memory cells in the immune response to PPS. These results help explain the poor PPS-specific antibody response post-vaccination in individuals deficient in IgM+/CD27 + B cells. When PPS-specific antibodies are not present, natural antibodies serve as the body's first line of defense against pneumococcal challenge. These low avidity, polyreactive anti-PPS antibodies have not been extensively studied in humans. We hypothesized that while these antibodies are low avidity, they elicit protection against pneumococcal challenge. In this project, PPS binding B cells were isolated using fluorescently labeled PPS and expanded in tissue culture. Although these antibodies were isolated from individual B cells and possessed unique VH/VL, sequence analysis and avidity studies revealed similar characteristics. The VL CDR3 was restricted in length and VH CDR3s expressed a statistically higher number of flexible amino acids when compared to PPS-specific antibodies. To investigate the role of the constant region in antibody avidity, these polyreactive variable regions were expressed as IgG1 or IgG2. Kinetic analysis demonstrated that IgG1 antibodies were more avid when compared to IgG2. The IgG1 isotype is more flexible than IgG2 allowing unrestricted movement to bind PPS antigens more avidly. Our results suggest IgM + memory cells respond to PPV and polyreactive antibodies possess specific characteristics that enable recognition of multiple PPS.

▼ Treating <i>Mycobacterium tuberculosis</i> (<i>M. tb</i>) infections in the 21st century is an increasingly daunting task, as antibiotic resistance has become more prevalent and treatment accordingly more complex. One property that makes <i>M. tb</i> so difficult to treat is its extremely hydrophobic, highly impermeable cell wall, most notably characterized by the presence of long chain, &agr;-branched mycolic acids. The Antigen 85 (Ag85) family of enzymes catalyze the transfer of mycolic acids from a single donor, trehalose monomycolate (TMM), to different acceptors located within the cell wall. Although there are three different pathways in <i>M. tb</i> to produce trehalose, only one, the <i>otsAB </i> pathway, leads to the production of TMM. Thus, inhibiting the Ag85 enzymes or the <i>otsAB</i> pathway may seriously damage the ability of <i>M. tb</i> to build the cell wall, and ultimately could affect the viability of the organism itself. The first part of this work describes the development of a real-time, high-throughput assay to assess enzyme activity and determine the steady-state parameters for one enzyme in the <i>otsAB</i> pathway, trehalose phosphate phosphatase (TPP), which catalyzes the hydrolysis of trehalose-6-phosphate (T6P) to produce trehalose. The assay was determined to be rapid, highly producible, and amenable for high-throughput screening. The second part of this work describes work done to kinetically and structurally characterize the second step of the Ag85 ping-pong mechanism, since previous studies have not elucidated the processes that govern recognition and transfer of mycolic acids to carbohydrate acceptors. A single-enzyme mediated, high-throughput assay using esterified fluorophores as acyl donors was developed to evaluate acyl acceptor selectivity, as well as a means to screen potential inhibitors. Although the assay produced promising results for Ag85C, a combination of high background and low activity hampered the ability to assess the second half-reaction of the Ag85A and Ag85B enzymes. However, the assay was successful in identifying and assessing compounds that inhibit acyl transfer catalyzed by Ag85C. Additionally, a serine to alanine active site mutant of Ag85C (S124A) was structurally characterized with and without the presence of carbohydrate-based detergents, providing insight regarding the acyl-enzyme intermediate form of the enzyme and its interactions with substrate and product analogs.

▼ This work focuses on Detroit from 1805 to 1812, with a focus on the changes brought about by the advent of the Michigan Territory and the reaction to those changes by the predominantly French-speaking citizens of the town. This work relies on previously underutilized petitions and memorials drafted and circulated by the francophone citizens of Detroit to argue that these citizens had a real and profound interest in the political and legal future of their town, contrary to what past historians have written. The thesis is organized into three chapters. The first gives a brief history of Detroit from its founding in 1701 until the start of the Territory of Michigan in 1805. The second examines the conflicting desires of the local population and the new administration in rebuilding the towns following its destruction by fire in June 1805, in particular the issues involving land title, locations of new lots, and the enclosure of Detroit's commons. The third chapter examines controversies surrounding the "Americanization" of the legal system in Detroit and the desire of the French-speaking population to have a system more in keeping with their traditional practices.

▼ Medical image fusion (MIF) is a key technique for the
analysis of diagnostic images in clinical applications. MIF aims to
reduce uncertainty and redundancy derived from examining two or
more multi-mode separate images, by creating one single composite
image that is more useful for human interpretation. However,
current MIF techniques have not successfully addressed the poor
textual properties and deficient edge formation of many resulting
images. In order to address these shortcomings, this dissertation
proposes a variety of algorithms aimed at exploiting different
combinations of well-known image processing and fusion techniques.
The first algorithm exploits the properties of Gabor filtering and
links maximum pixel selection with fuzzy-based image fusion, in
order to improve the textual and edge properties of the fused
medical images. The second algorithm focuses on reducing defects
associated with single images created from different modalities by
combining the action of Gabor filtering, maximum pixel intensity
selection and Pulse Coupled Neural Network (PCNN) implementation.
The third algorithm seeks to increase image information content and
provide a complementary context for anatomical and physiological
information by using a space-variant Wiener filter followed by
image enhancement with lateral inhibition and excitation in a
feature-linking PCNN under maximized normalization, and then fusion
using a shift-invariant discrete wavelet transform (SIDWT). The
fourth algorithm focuses on increasing the quality of the source
images through a preprocessing technique which uses a
greedy-iterative strategy for local contrast enhancement in order
to minimize global image variance, together with global and local
image contrast optimization based on the human visual system and a
standard fusion algorithm. The fifth algorithm attains fusion in
the Discrete Cosine Transform (DCT) domain under a novel Block
Toeplitz matrix designed to enhance the finer details of all input
images, followed by contrast adjustment and smoothing by bilateral
filters using Gaussian kernels. All the novel MIF methods are
discussed, thoroughly described, applied to a set of medical images
and then evaluated and compared to existing fusion algorithms in
terms of three objective measurements, namely pixel standard
deviation, root-mean square error and image entropy. Most of these
performance figures show significant improvements when compared to
the reference fusion methods, thus suggesting that the newly
developed algorithms represent a valuable contribution towards
progress in this important application field.

▼ Training healthcare professionals and providing them
with the skills and competencies required for their discipline is
essential to reduce medical errors and enhance the efficiency of
healthcare procedures. Simulation-Based Medical Education (SBME) is
an attempt to provide means to train healthcare professionals.
However, due to the lack of standard tools for delivery and
assessment of medical simulation, performance during SBME is
routinely evaluated by basic pass/fail metrics followed by
instructor-led debriefing. Such assessments do not provide a
detailed analysis of skills acquired by the learners or provide
insight into future training requirements. To address the needs and
limitations of current SBME procedures, this thesis proposes an
open-access multi-tiered cloud-based learning management system
(LMS) PREPARE, that supports PREdiction of Healthcare Provider
Skill Acquisition and Future Training REquirements. PREPARE was
built using evidence-based SBME guidelines and is an attempt to
transform the current process of creating and administrating SBME
into an intuitive data-driven platform.To evaluate the capabilities
of PREPARE, we conducted a pilot study at the
University of
Toledo’s Interprofessional Immersive Simulation Center (IISC). With
this study, PREPARE was able to establish its utility as an
effective tool to standardize creation, assessment, and delivery of
SBME. It gives a platform to the instructors to create SBME
curriculum in a digital format, which includes curriculum
goals/objectives, customizable preassessment and postassessment
forms (to determine baseline and post-SBME knowledge and skills).
Based on the designed curricula, instructors can define the
simulation scenarios that consist of “learning events” focused on
enhancing skills required to meet the objectives and the goals.
PREPARE allows the instructors to give performance ratings and
feedback across learners based on their participation.
Additionally, PREPARE collects and process physiological data from
learners during participation in SBME to provide potential
objective performance measures related to knowledge and skill
acquisition. Finally, it also helps the instructor analyze the
average performance of learners across a SBME curricula to evaluate
which of the curriculum’s goals and objectives were
achieved.

▼ The digital age has transformed what defines a typical
college student. Today’s students have grown up in the
technological world where almost any desired information can be
accessed with the touch of a fingertip. For this reason, it is
unsurprising that educators are encouraged to incorporate
technological instructional aids in curriculum to help enhance the
learning environment. In a fast-paced technical world, selecting
appropriate technological instructional aids can be an overwhelming
experience for educators.While offering quality web-based
instruction is vital to the success of post-secondary institutions,
there remains limited research as to which technological
instructional aids are most effective for web-assisted courses in
higher education. Therefore, the purpose of this study was to
examine reported, effectiveness, efficiency, appeal, and
satisfaction of technological instructional aids (ALEKS, YouTube,
and ECHO360) in a web-assisted college algebra course. In addition,
the researcher investigated how effective students perceived ALEKS,
YouTube, and Echo360, amongst how much time was invested in using
technological instructional aids for college algebra, the type of
high school students attended, and previous experience with using
technology in the classroom. Lastly, the researcher compared the
statistical means of ALEKS, YouTube, and Echo360. The results of
this study showed that students’ perceptions of effectiveness for
three types of instructional aids (ALEKS, YouTube, and Echo360) did
not change regarding their previous technology experiences in the
classroom. The findings also suggested that a student’s background
in terms of their educational experience (high school category and
high school systems) did not affect how effective students
perceived the instructional aids to be. Additionally, students’
perceptions of the effectiveness of each instructional aid were not
determined by the amount of time spent utilizing the instructional
aids. Lastly, the study showed that students perceived ALEKS more
effective and satisfying than YouTube and Echo360. However,
students found YouTube more appealing. Therefore, it would
beneficial for educators to continue research in quality web-based
instruction and to re-evaluate current curriculum.

▼ Posttraumatic stress disorder (PTSD) has previously
been found to be inversely related to distress tolerance, which is
the ability to tolerate negative or aversive emotional states
(Simons & Gaher, 2005), in trauma-exposed samples. The vast
majority of the studies examining the relationship between these
two constructs have used DSM-IV PTSD criteria. Additionally,
although previous research has considered their relationship at the
symptom cluster level (Fetzner et al., 2014; Vujanovic et al.,
2013), this is the first study to examine it at the latent level of
analysis. Confirmatory factor analysis (CFA) was used to determine
whether the DSM-5 model of PTSD or the dysphoria model of PTSD
provided a better fit for the data. CFA was also used to test the
five-factor hierarchical model of the Distress Tolerance Scale
(DTS; Simons & Gaher, 2005), and then Wald tests of parameter
constraints were utilized to determine if the magnitude of the
relationships between individual PTSD factors and the second-order
DTS factor differed significantly. Results indicated that the
four-factor dysphoria model of PTSD provided a significantly better
fit compared to the DSM-5 four-factor model of PTSD. Additionally,
all four factors of PTSD (re-experiencing, avoidance, dysphoria,
and arousal) were negatively correlated with the higher-order
general distress tolerance factor of the DTS. However, when these
factor correlations were compared pairwise using Wald tests of
parameter constraints, none of them were differentially related to

▼ The use of Metal working fluids for any cutting
mechanism has been found to affect the tool wear in a positive
manner, but more importantly it is the way of applying this fluid
that has significantly impacted the tool wear. In this study,
experiments were conducted on AISI 4140 alloy steel to determine
the performance of three different applications of cutting fluid
using an end milling process. TiAlN coated metal carbide inserts
were used for cutting under three different levels of surface
speed, chip load and depth of cut. The response variables collected
were Acoustic Emission (AE), Forces, Temperature and Tool wear
based on which, cutting fluid applications were categorized for
their performances. In addition, more emphasis was given on the AE
results to observe its potential to provide necessary real time
knowledge and tool wear monitoring capability during cutting
process. AE Hit values were recorded as a parameter to study the
tool wear results based on different ways of fluid applications.
The results in this research point to the fact that different ways
of applying a cutting fluid impacts the tool wear, forces,
temperature and the acoustic signals in a positive manner.
Furthermore, three statistical models to predict the tool wear in
near future were proposed based on the response variables from this
research.

▼ Hardware security threats have become a major issue in
the technology sector and cyberspace. In 2011, more than 1300
counterfeit incidents were reported from around the world to the
Electronic Resellers Association International (ERAI). The
incidents reported in 2011 were more than double compared to the
incidents reported in 2010 and 2008. The federal contract report
states that counterfeiting of electronic parts has threatened the
operability and reliability of the US weapons system. Electronic
parts counterfeiting has become a very big business perpetrated by
corrupt operators. Just like ASIC semiconductors, reconfigurable
hardware is also prone to hardware security threats. The most
commonly used reconfigurable hardware is the Field Programmable
Gate Array (FPGA). Demand for FPGAs has increased as can be seen by
the growth in FPGA companies such as Xilinx and Altera. Despite the
increased demand and use of FPGAs in the market, there is a great
concern that security is not currently a part of the FPGA hardware
and software to the fullest extent. Design theft, and hardware
tampering threats on FPGAs can be dealt using Ring Oscillator
Physical Unclonable Function (ROPUF). A ROPUF takes advantage of
the process variation on a silicon chip to generate a unique ID for
the purpose of authentication. A ROPUF can be implemented on an
FPGA chip to produce a unique ID for each FPGA chip. An adversary
that tries to tamper with the ROPUF inadvertently changes the
properties of the process variation in the silicon chip; thus any
tampering attempt can be detected. In this research, ROPUF based
hardware security for FPGAs is presented. A total of 50 Xilinx
FPGAs are used in our investigation. Performance in terms of
uniqueness and reliability is evaluated. The effects of temperature
variation, voltage variation, and aging on these parameters are
also studied. Our work shows that lower number of stages used in
the Ring Oscillator (RO) offers better security feature. The lower
number of stages used in ROs yield higher Challenge and Response
Pairs (CRPs). The higher number of CRPs contributes to higher
security. In addition, we have introduced a technique called Random
Patch Mixer (RPM) to minimize the systematic variations effect on
the frequency generated from ROPUFs on FPGA. The results obtained
by using RPM technique are shown to be better than other techniques
that have been proposed before. The responses generated from ROPUF
after applying the RPM technique passed most of the NIST
statistical test for randomness. Finally, we show how the ROPUF can
be used for the security of a Smart Grid. The security of ROPUF
system is also tested using support vector machine (SVM). The SVM
is trained using a large data set of challenges to predict the
response sets. Results obtained show that the SVM fails to predict
ROPUF responses based on the challenges, thus enhancing the
security offered by the proposed authentication
system.

▼ The quality of online courses has an impact on
retention and student satisfaction in higher education. Designing
online courses using best practice standards is a critical role for
faculty members in higher education. Therefore, many institutions
are adopting best practices in the instructional design of online
courses. However, little is known about whether faculty members in
higher education are adopting best practice standards in designing
their online courses. The purpose of this study was to discover if
faculty members adopt best practice standards in the creation of
higher education online courses. The results revealed that higher
education faculty members do adopt best practice standards in the
design of their online courses. In addition, the study determined
that full-time versus part-time faculty status is the strongest
predictor for the adoption of best practice standard for online
course design. It was also indicated that full-time and part-time
faculty have different motivational factors for adopting best
practice standards for online course design. Lastly, the study
indicated that institutions would benefit in providing different
types of faculty development delivery methods in the design of
quality online courses.

An Evaluation of Changes in Cognitive Appraisal and Emotion

▼ The primary theories (Ehlers & Clark, 2000; Foa
& Kozak, 1986) concerning the development and maintenance of
posttraumatic stress disorder (PTSD) are cognitive in nature.
Subsequently, the front-line treatments for PTSD have been
cognitive behavioral treatments; however, research examining the
efficacy of these treatments has largely excluded individuals with
serious mental illness (SMI) as participants. Thus, research on
treatments for PTSD in individuals with SMI is limited, and only
cognitive treatments for this population have been examined (Frueh
et al., 2009; Mueser et al., 2008). Recent literature (Ehring &
Quack, 2010; Price, Monson, Callahan, & Rodriguez, 2006) has
emerged demonstrating that programs focused on improving emotion
regulation (ER) in individuals who have PTSD are effective (Kearney
et al., 2012; Kimbrough et al., 2010); however, research is still
lacking concerning the use of this treatment modality with
individuals with comorbid PTSD and SMI. Wellness Management and
Recovery (WMR), a psychoeducational group program aimed at
promoting mental health recovery in individuals with SMI has
recently been evaluated and determined to be associated with
reductions in PTSD in individuals who have completed the program
(Lee, 2011). However, the mechanisms through which WMR works remain
unclear. As a result, the purpose of the current study was to
utilize self-report measures of PTSD symptoms, cognitive appraisal
of a traumatic event, and ER to determine whether or not WMR’s
impact on trauma-related beliefs or ER significantly predicted
participants’ reduction in PTSD symptoms. Results of the present
study demonstrated that following participation in WMR,
individuals’ self-reported levels of PTSD symptoms, trauma-related
cognitions, and ER difficulties decreased. Regression analyses
revealed that both changes in cognition and ER predicted changes in
participants’ self-reported levels of PTSD symptoms; however,
changes in ER were found to be the superior predictor, predicting
18% more of the variance in change in PTSD symptoms than did
changes in trauma-related cognitions. The results of this study
suggest that PTSD treatments developed for individuals with SMI may
be most effective if interventions aimed at increasing ER skills
are integrated into treatment protocols.

▼ Depression is a leading cause of illness and
disability among adolescents worldwide (World Health Organization
[WHO], 2014b). Adolescent depression is associated with higher
rates of its reoccurrence in adulthood (Gladstone et al., 2011),
and represents a significant cost burden on personal and societal
scales (Greden, 2001; Tuisku et al., 2014). Researchers have sought
to identify positive and negative correlates for the reduction of
depressive symptoms among adolescents (Allison et al., 2005; Bilski
et al., 2013; Koivumaa-Honkanen et al., 2004; Muris et al., 2001).
Religiousness/spirituality has been consistently identified as a
negative correlate in adult depression (Bonelli et al., 2012;
Koenig et al., 2001) as well as adolescent substance use and other
health related problems (Amoateng & Bahr, 1986; Dew et al.,
2008; Kent, 1990; Knight et al., 2007; Rew & Wong, 2006;
Ritt-Olson et al., 2004). However, the relationship between
religiousness/spirituality and adolescent depression remains
ambiguous and requires further study (Dew et al., 2008). Recently,
the nature of the religiousness/spirituality construct was
recognized as multidimensional and inter-related (Fetzer Institute,
2003; Wong et al., 2006). Forgiveness, as one of the dimensions of
religiousness/spirituality, has been vigorously researched in adult
health-related outcomes (Toussaint et al., 2008), including adult
depression (Thompson et al., 2005). However, only a few studies
have examined the relationship between forgiveness and depressive
symptoms among adolescents (Dew et al., 2008; Dew et al., 2010).The
purpose of the study was to examine the relationship between
forgiveness and depressive symptoms reported by 12 to 18 year old
adolescents who routinely visited three ethnically diverse family
medicine clinics in the New England area. The study focused on
three dimensions of forgiveness: intrapersonal (forgiving self),
interpersonal (forgiving others), and divine (knowing that God
forgives). Additionally, other relationships were examined as they
related to gender and developmental stages of young, middle, and
late adolescence. The study used previously collected data that was
used for publication by the Center for Adolescent Substance Abuse
Research [CeASAR] (Knight et al., 2007; Harris et al., 2008). Chi
square analyses were used to examine whether observed frequencies
between each dimension of forgiveness and depression, each
dimension of forgiveness and developmental stage, and each
dimension of forgiveness and gender would significantly differ from
what would be expected by chance.Results of the current study were
not found to be statistically significant, which is incongruent
with previous studies examining depression and forgiveness among
adolescents in psychiatric outpatient (Dew et al., 2008) and
inpatient (Dew et al., 2010) settings. The lack of significant
findings and inconsistency with previous research might indicate
the absence of an association between the three dimensions of
forgiveness and depression across gender and developmental…

Realization of Miniaturized Multi-/Wideband Microwave

▼ The ever-growing demand toward designing microwave
front-end components with enhanced access to the radio spectrum
(e.g., multi-/wideband functionality) and improved physical
features (e.g., miniaturized circuitry, ease and cost of
fabrication) is becoming more paramount than ever before. This
dissertation proposes new design methodologies, simulations, and
experimental validations of passive front-ends (i.e., antennas,
couplers, dividers) at microwave frequencies. The presented design
concepts optimize both electrical and physical characteristics
without degrading the intended performance. The developed designs
are essential to the upcoming wireless technologies.The first
proposed component is a compact ultra-wideband (UWB) Wilkinson
power divider (WPD). The design procedure is accomplished by
replacing the uniform transmission lines in each arm of the
conventional single-frequency divider with impedance-varying
profiles governed by a truncated Fourier series. While such
non-uniform transmission lines (NTLs) are obtained through the
even-mode analysis, three isolation resistors are optimized in the
odd-mode circuit to achieve proper isolation and output ports
matching over the frequency range of interest. The proposed design
methodology is systematic, and results in single-layered and
compact structures.For verification purposes, an equal split WPD is
designed, simulated, and measured. The obtained results show that
the input and output ports matching as well as the isolation
between the output ports are below –10 dB; whereas the transmission
parameters vary between –3.2 dB and –5 dB across the 3.1–10.6 GHz
band. The designed divider is expected to find applications in UWB
antenna diversity, multiple-input-multiple-output (MIMO) schemes,
and antenna arrays feeding networks. The second proposed component
is a wideband multi-way Bagley power divider (BPD). Wideband
functionality is achieved by replacing the single-frequency
matching uniform microstrip lines in the conventional design with
NTLs of wideband matching nature. To bring this concept into
practice, the equivalent transmission line model is used for
profiling impedance variations. The proposed technique leads to
flexible spectrum allocation and matching level. Moreover, the
resulting structures are compact and planar. First, the analytical
results of three 3-way BPDs of different fractional bandwidths are
presented and discussed to validate the proposed approach. Then,
two examples of 3- and 5-way BPDs with bandwidths of 4–10 GHz and
5–9 GHz, respectively, are simulated, fabricated, and measured.
Simulated and measured results show an acceptable input port
matching of below –15 dB and –12.5 dB for the 3- and 5-way
dividers, respectively, over the bands of interest. The resulting
transmission parameters of the 3- and 5-way dividers are –4.77±1 dB
and –7±1 dB, respectively, over the design bands; which are in
close proximity to their theoretical values. The proposed wideband
BPD dividers find many applications in microwave front-end
circuitry, especially in…

▼ This study examines the lived experience of
first-generation African-American female students at Macomb
Community College (MCC) in Warren, Michigan. The purpose of this
research study was to explore the lived experiences of resilient
and successful first-generation African-American female community
college students. This qualitative study used a phenomenological
approach, specifically a social constructionism perspective, and
semi-structured interviews. Using an Appreciative Inquiry (AI)
interview technique, the researcher selected students who met the
inclusion criteria, which consisted of attending MCC community
college for two or more semesters. Six themes emerged: (a) Family
Support, (b) College Highlights, (c) Self-Reliance/Independence,
(d) Self-Identification, (e) Adversity, (f) Overcoming Life
Challenges. The insights and result of this study can be used by
high school and postsecondary administrators, counselors, faculty
members, and career coaches to re-examine current best practices,
to redefine academic success, and to launch programs specifically
designed for first-generation students based upon their specific
needs and perspective.

▼ In clinical and forensic practice, professionals often
use dolls and human figure drawings (HFDs) to question young
children about touch events. These professionals assume children
understand the representational nature of the props. However,
recent work has shown even 5-year-olds make some errors when using
props to show touch occurring on them. The purpose of the present
study was to examine whether requiring children to use their own
bodies impeded their performance in showing touches when using
drawings and dolls as representations. Children’s use of 2D line
drawings and 3D objects (i.e., scale models and dolls) as symbols
was assessed on three tasks. All children used the symbols to show
touch occurring on their own bodies, touch occurring on another
person’s body, and to guide their search for a hidden object. For
all tasks, children’s performance improved with age; however, even
5-year-olds made some errors showing touch locations. Findings
revealed that asking children to use their own bodies did affect
their accuracy in using dolls and drawings as symbols. When asked
to show touch locations on another person, children’s performance
was intermediate to the other two tasks. Children demonstrated
improved performance in showing touch locations on another person
as compared to their own bodies. However, this finding was
qualified by a significant interaction. Children made the most
errors when asked to use 2D drawings to show touch locations that
occurred on their own bodies as compared to any other task/symbol
combination. Forensic applications and theoretical implications of
the findings are discussed.

▼ Wireless sensor networks are a collection of small,
disposable, low-power devices that monitor vital sensory data for a
variety of civil, military, and navigational applications. For
instance, some cities have a network of emergency phones scattered
across walkways so that citizens in distress can immediately reach
emergency services. Using effective localization techniques that
are both highly accurate and of low computational cost, 911
services can dispatch police, fire, or medical services to a
caller's location as quickly as humanly possible. Hence, from the
standpoint of locating a node in a network, every percent of
accuracy achieved and every second of time saved can be the
difference between life and death. This thesis presents two novel
algorithms for wireless sensor network localization through the
incorporation of Dempster-Shafer Evidence Theory. The first
technique follows a verbose methodology for node positioning that
fuses multiple types of signal measurements, such as received
signal strength and angle of arrival, and utilizes the expected
value property of DS Theory to geo-locate a node with a moderate
accuracy of 78-87%, thereby providing an introductory approach to
the previously untapped fusion of WSN localization and DS
Theory.The second approach consists of a low cost, highly accurate
data fusion technique that incorporates the plausibility property
of DS Theory to establish a high level of accuracy. Due to this
unique approach to data fusion and predictive data modelling, this
second algorithm achieves an optimal accuracy range of 83-98% in a
flexible multitude of simulation scenarios at a fraction of the
runtime required under prior established localization techniques.
Overall, these two algorithms provide a groundbreaking new
application of Dempster-Shafer Theory as well as fast, accurate,
and informative new approaches to wireless sensor network
localization that can improve a wide range of vital
applications.

▼ Previous exertions of self-control can affect
subsequent risk preferences usually resulting in risk-seeking
tendencies. A few studies, however, have found that reductions in
self-control resources (i.e., “ego depletion”) can decrease
risk-taking resulting in relative risk-aversion compared to
non-depleted controls. In efforts to explain these contradictory
results, three experiments examined whether certain task features
predicted when ego depletion would lead to increased or decreased
risk-taking. Across different variations of the Columbia Card Task
(CCT), the ego depleted risked less than their non-depleted
counterparts when task features promoted feelings of perceived
control (Experiments 1-3). Manipulations aimed at reducing
perceived control eliminated this depletion effect and
descriptively reversed the trend, such that the ego depleted were
risking more than the controls. Ego depletion also affected some
aspects of participant’s information use on the CCT. While both the
ego depleted and the non-depleted were sensitive to changes in gain
amount and probability, the ego depleted were insensitive to
changes in loss amount (Experiment 1). Experiment 2 also showed
that trait self-control moderated the ego depletion effect under
conditions of low, but not high perceived control. Results of
Experiment 3 suggested that the previous inconsistencies in the
literature were not due to differences in risk-taking tasks
requiring experienced-based learning. Together these results
provide a more nuanced account for the effect of ego depletion on
risk preferences and offer potential explanations for previous
inconsistencies reported in the literature.

▼ Thermoplastic composites are suitable alternatives to
metals in some load-bearing applications such as in the automotive
industry due to a large number of advantages they present. These
include light weight, ease of processing for complex geometries at
high production rate, outstanding cost to performance ratio,
ability to reprocess, and corrosion resistance. Addition of fillers
such as talc or reinforcements such as short glass fibers can
improve the mechanical performance of unreinforced thermoplastics
to a high degree.Components made of thermoplastic composites are
typically subjected to complex loadings in applications including
static, cyclic, thermal, and their combinations. These applications
may also involve environmental conditions such as elevated
temperature and moisture which can dramatically affect their
mechanical properties.This study investigated tensile, creep,
fatigue, creep-fatigue interaction, and thermo-mechanical fatigue
(TMF) behaviors of five thermoplastic composites including short
glass fiber reinforced and talc-filled polypropylene, short glass
fiber reinforced polyamide-6.6, and short glass fiber reinforced
polyphenylene ether and polystyrene under a variety of conditions.
The main objectives were to evaluate aforementioned mechanical
behaviors of these materials at elevated temperatures and to
develop predictive models to reduce their development cost and
time. Tensile behavior was investigated including effects of
temperature, moisture, and hygrothermal aging. Kinetics of water
absorption and desorption were investigated for polyamide-6.6
composite and Fickian behavior was observed. The reductions in
tensile strength and elastic modulus due to water absorption were
represented by mathematical relations as a function of moisture
content. In addition to moisture content, aging time was also found
to influence the tensile behavior. A parameter was introduced for
correlations of normalized stiffness and strength with different
aging times and temperatures. Higher strength and stiffness were
obtained for re-dried specimens after aging which was explained by
an increase in crystallinity. Mechanisms of failure were identified
based on fracture surface microscopic analysis for different
conditions. Creep behavior was investigated and modeled at room and
elevated temperatures. Creep strength decreased and both creep
strain and creep rate increased with increasing temperature. The
Larson-Miller parameter was able to correlate the creep rupture
data of all materials. The Monkman-Grant relation and its
modification were successfully used to correlate minimum creep
rate, time to rupture, and strain at rupture data. The Findley
power law and time-stress superposition principle (TSS) were used
to represent non-linear viscoelastic creep curves. Long-term creep
behavior was also satisfactory predicted based on short-term test
data using the TSS principle.Effect of cycling frequency on fatigue
behavior was investigated by conducting load-controlled fatigue
tests at several stress ratios and at several…

▼ Relational aggression is often conceptualized as an
individual and social problem. However, a comprehensive review of
the literature reveals a much more ambiguous story. There is both
an empirical and theoretical basis for exploring the possibility
that an alternative conceptualization of this phenomenon may be
more accurate. In the current project, an empirical investigation
was conducted to compare the dominant pathological
conceptualization of relational aggression to an alternative
conceptualization. The Young Adult Conflict Resolution and
Aggression questionnaire, the Indirect Aggression Scale, and the
Mental Health Inventory were completed by 209 college students.
Curvilinear regressions were conducted to obtain goodness-of-fit
statistics for both linear and curvilinear models of the
relationship between relational aggression and both psychological
distress and anxiety. While a curvilinear model was significant for
both analyses, the slope was in the opposite direction than
anticipated. Similarly, contrary to expectations, follow-up t-tests
on the residuals suggested that neither model was a statistically
significant “better fit” to the data for either of the analyses.
Implications of the results are discussed and limitations and
recommendations are outlined. While results of the current study
are not conclusive, findings suggest that further theoretical and
empirical examination of alternative conceptual models of
relational aggression is warranted.

An Alternative Strengthening Technique using a Combination

▼ The present research in this study is directed towards
improving the flexural performance, namely the load and
displacement ductility capacities, and exploring the various
failure modes, of continuous reinforced concrete (RC) slab strips.
This improvement is accomplished by applying fiber reinforced
polymers (FRP) of two types: FRP sheets and FRP rods, in both
positive and negative regions of moment of the continuous RC slab
strip. Currently, experimental research has shown that applying FRP
rods using the near surface mounted (NSM) method to strengthen
continuous RC structures can greatly improve flexural capacity and
moment redistribution. Despite the benefits of FRP rods through the
NSM method, applying FRP sheets using the externally bonded
reinforcement (EBR) method is more common due to its ease of
application and cost. Thus, this study takes into account the
benefits of both NSM & EBR strengthening techniques, and
presents an alternative strengthening combination using EBR-FRP
sheets to strengthen the positive moment or sagging region, and
NSM-FRP rods to strengthen the negative moment or hogging region of
continuous RC slabs strips. Currently, the challenges faced when
using FRP strengthening depends on the type of FRP material used.
The EBR-FRP sheets suffer from debonding (loss of stress transfer
between concrete-FRP) failures when facing high moments. To prevent
these, anchorages can be provided. These anchorages are however,
expensive and their applicability is limited. NSM-FRP rods suffer
from sudden FRP rupture but are generally safer to use than FRP
sheets. However, they require cutting of grooves on the concrete
surface limiting their applicability in certain regions as well.
The presented alternative strengthening combination aims at
overcoming these drawbacks by applying EBR-FRP sheets in most
locations while reducing the need for anchorages, and using NSM-FRP
strengthening only in locations that benefit from concrete cover.
Through, complex finite element analysis (FEA), the effectiveness
of this combined strengthening method is investigated. Parametric
studies to study the influences of carbon fiber reinforced polymer
(CFRP) and glass fiber reinforced polymer (GFRP), various FRP
reinforcement ratios (¿_frp^ ), and width of EBR sheet, on the
flexural load and displacement ductility capacities, concrete-FRP
bond strength, and failure modes, are also discussed. The general
conclusion from this study indicates that the combination of using
both EBR and NSM techniques simultaneously is more effective than
using either EBR or NSM independently. CFRP material provided
better load capacity and displacement ductility than GFRP; however
GFRP led to more predictable failure modes. Overall, the sagging
region FRP showed higher influence in increasing the load capacity
and ductility. The hogging region FRP showed higher influence on
the type and location of failure mode. Additionally, the hogging
region FRP had a detrimental effect on the ductility when
increased. The width of FRP sheets had a low impact on…

▼ The purpose of this research is to design a
computational decision support system (DSS) for compounded sterile
preparations (CSP). Error-free compounding is dependent on the
proper selection of components and adherence to procedure during
compounding. A material selection system (MSS) based on a graphical
user interface (GUI), coupled with a barcode scanner and back-end
database, has been developed and tested for proper selection of
items involving three different medication orders (MO). A video
processing system (VPS) has been implemented in MATLAB that
evaluates the live video feed from the compounding hood to monitor
the compounding procedure when compounding the MO’s. Surf detection
is used to detect and locate compounding items placed in the hood.
Various algorithms have been developed and tested to enhance the
accuracy and robustness of the VPS. The Decision Support System
(DSS) is further improved with integration of another digital
camera to ensure that correct volume of medicine with appropriate
syringe is performed during the whole compounding process. The
template matching and SURF object detection application on the
digital image of the syringe, along with minimum distance
classifier and artificial neural networks (ANNs) on the previously
collected data from several experimental observations, were
explored in classification and volume measurement of a syringe.The
MSS was tested for all items used in compounding the MO’s and
performed error-free. The VPS evolved to VPS.03 from VPS.01 and
VPS.02. The greatest accuracy and ability for real-time realization
were seen in VPS.03. All deliberate mistakes made when compounding
the tested medication orders were captured by VPS.03. Leur-lock
syringes of different sizes from 1 mL to 30 mL were tested, and an
accuracy of 95+ % was obtained with very high precision.The new
computational decision support system facilitates error-free
selection of components and is able to monitor and evaluate the
compounding process and correct volume measurement in real time.
The platform may be used in CSP compounding rooms to audit
techniques and procedures as well as in training or educational
settings.

▼ The Veterans’ Glass City Skyway (VGCS) Bridge is a
large cable-stayed bridge, which crosses Maumee River in
Toledo,
Ohio. It is located in an area, which has a history of icing
events. Since starting operation in June 2007, six major icing
events have occurred. The icing events have resulted in lane and
bridge closures. These icing events cause a potential hazard for
motorists traveling on the bridge from the falling ice. The Ohio
Department of Transportation (ODOT) chose to pursue an
administrative management approach for the icing problem of the
VGCS. This strategy involves the development of real-time
monitoring system to detect the presence, condition, and thickness
of ice on the stay which helps bridge operators to make the
appropriate decisions. In order to provide the accurate data to the
monitoring system, a sensor network was implemented on the bridge.
This includes two new sensors developed by the UT icing research
team: the UT Ice Presence and State Sensor (UT State Sensor) and
the UT optical thickness sensor. These sensors were deployed on the
VGCS in the summer of 2015. The UT State Sensor mounts on the stay
surface to detect whether water on the stay is liquid or ice. This
is critical because water beneath the ice is a precursor to ice
shedding and existing sensors do not directly measure conditions on
the stay. The UT State Sensor found the water beneath the ice layer
during the laboratory experiments performed indoors and at UT’s
outdoor field station. The UT Optical Thickness Sensor reports the
thickness of ice present on the stay. The UT Optical Thickness
Sensor was successfully tested in indoor laboratory.The field
testing of the UT State Sensor was performed in the winter of
2015-16 on the VGCS. The data from the sensor was studied and
compared to the field observation made by the ODOT personnel for
several days. This winter had some days where there was a thin
layers of ice formed in some places on the stays, but no ice which
could cause shedding hazard was formed. The visual observations
were compared with sensor output. The UT State Sensor showed ice in
the same position as was observed on December 5, 2015 and December
6, 2015. The sensor output did not match the visual observation on
February 24, 2016 event. The output from the UT State Sensor during
the field testing on the VGCS was promising and it was concluded
that more field testing was necessary. Experiments were conducted
to determine the accuracy of the UT State Sensor in detecting water
beneath the ice. Thirty-one freeze – thaw cycles were performed on
the UT State Sensor and compared its result with visual inspection
of ice. The UT State Sensor always indicated the ice to water
transition and found the water beneath the ice, which is a
precursor to shedding. Also, the UT State Sensor was able to detect
the ice presence with significant accuracy. Overall, sensors that
can make direct measurements of conditions on the stay were
developed. This includes the ability to measure water beneath the
ice. This layer of water is a precursor to…
