Carbon fiber-based chemiresistors for structural health monitoring

description: With the increasing demand for durable infrastructure in chemically aggressive environments, the development of self-sensing cement-based materials has emerged as a promising approach for real-time SHM. Traditional methods of assessing infrastructure often rely on periodic inspections, which are not only costly and time-consuming but also limited in their ability to detect early-stage deterioration. This thesis investigates the development and application of carbon fiber-reinforced cement-based chemiresistors designed to detect chemical-induced degradation in concrete infrastructure. The research addresses a critical gap in Structural Health Monitoring, where traditional piezoresistive sensors primarily focus on strain detection, overlooking the effects of chemical exposure. The study explores the performance of these chemiresistors under exposure to 5% NaCl, 3% and 7% H₂SO₄, 10% and 20% NH₄NH₃, simulating conditions found in marine environments, wastewater systems, and agricultural settings. Cement composites incorporating two types of carbon fibers and hybrid fiber systems (carbon and steel fibers) were fabricated and subjected to cyclic wetting-drying exposure at 50ºC for 30 days to accelerate degradation and create a more realistic environment. Electrical resistivity and UPV were used to monitor degradation over time. The result of this research discusses the best type of carbon fiber, fiber content, and a range of FCR that is expected to be seen after 30 days of exposure. The research introduces cement-based chemiresistors as a novel SHM solution for detecting chemical damage in real time. The dual assessment of resistivity and UPV provided a comprehensive understanding of both electrical and mechanical degradation mechanisms. This enhances sensor performance. The findings have significant implications for developing smart, self-sensing materials capable of improving the durability and safety of critical infrastructure exposed to harsh chemical environments

description: The PULSE@Parkes project has been designed to monitor the rotation of radio pulsars over time spans of days to years. The observations are obtained using the Parkes 64-m and 12-m radio telescopes by Australian and international high school students. These students learn the basis of radio astronomy and undertake small projects with their observations. The data are fully calibrated and obtained with the state-of-the-art pulsar hardware available at Parkes. The final data sets are archived and are currently being used to carry out studies of 1) pulsar glitches, 2) timing noise, 3) pulse pro. le stability over long time scales and 4) the extreme nulling phenomenon. The data are also included in other projects such as gamma-ray observatory support and for the Parkes Pulsar Timing Array project. In this paper we describe the current status of the project and present the first scientific results from the Parkes 12-m radio telescope. We emphasise that this project offers a straightforward means to enthuse high school students and the general public about radio astronomy while obtaining scientifically valuable data sets.

description: The world is facing a triple planetary crisis consisting of climate change, biodiversity loss, and pollution, which pose a major challenge to human health, well-being and prosperity for present and future generations. One of the main reasons for this is our current production and consumption system. Consequently, the entire production and consumption system and the entire value chain of products and services must be considered to minimise those unsustainable levels. Circular economy aims to transform our economy from the current mostly linear take-make-waste model towards a closed-loop model. In doing so, a circular economy can minimise the use of materials and energy, while reducing environmental pressures. This report therefore analyses how circular economy can contribute to halting biodiversity loss. It concludes that while circular economy measures (directly and indirectly) contribute to meeting biodiversity and climate strategic objectives, the combination with biodiversity-friendly sourcing is crucial in order to halt biodiversity loss. © European Topic Centre on Circular economy and resource use, 2022

description: The ability to think about another person’s mental state derives from what commonly referred to in psychology as our Theory of Mind. Our ability to attribute mind to others depends on several factors such as familiarity to the person, our relationship with the individual or our past experiences about the person’s behaviour. This study provides an insight into effect of social factors such as group membership and behaviour on children’s Theory of Mind by assessing the amount of mental effort children apply to make accurate judgments about people and their beliefs depending on their characteristics.

description: The analysis of high-precision timing observations of an array of ~20 millisecond pulsars (a so-called 'timing array') may ultimately result in the detection of a stochastic gravitational-wave background. The feasibility of such a detection and the required duration of this type of experiment are determined by the achievable rms of the timing residuals and the timing stability of the pulsars involved. We present results of the first long-term, high-precision timing campaign on a large sample of millisecond pulsars used in gravitational-wave detection projects. We show that the timing residuals of most pulsars in our sample do not contain significant low-frequency noise that could limit the use of these pulsars for decade-long gravitational-wave detection efforts. For our most precisely timed pulsars, intrinsic instabilities of the pulsars or the observing system are shown to contribute to timing irregularities on a 5-year time-scale below the 100ns level. Based on those results, realistic sensitivity curves for planned and ongoing timing array efforts are determined. We conclude that prospects for detection of a gravitational-wave background through pulsar timing array efforts within 5 years to a decade are good.

description: The first direct detection of gravitational waves may be made through observations of pulsars. The principal aim of pulsar timing-array projects being carried out worldwide is to detect ultra-low frequency gravitational waves (f ~ 10â-9â-10â-8 Hz). Such waves are expected to be caused by coalescing supermassive binary black holes in the cores of merged galaxies. It is also possible that a detectable signal could have been produced in the inflationary era or by cosmic strings. In this paper, we review the current status of the Parkes Pulsar Timing Array project (the only such project in the Southern hemisphere) and compare the pulsar timing technique with other forms of gravitational-wave detection such as ground- and space-based interferometer systems.
A multi-agent extension of Negoplan and its application to a business strategy game.

description: Negoplan is a domain-independent decision support system which can be customised for different application domains. Negoplan enables the representation, simulation and support of sequential, context-dependent decision-making problems that involve the interaction between two participants and their decision environment. This thesis presents extensions that increase the expressiveness of Negoplan's constructs. They enable Negoplan to represent decision-making problems that involve more than two participants. This enlarges substantially the class of Negoplan's applications. The usefulness of the extensions is demonstrated on a managerial decision-making application that involves more than two participants. This Negoplan application concerns self-training of a Business Administration student to test his managerial decision-making skills in an environment in which Negoplan represents two other autonomously behaving participants. The application also demonstrates the suitability of customised Negoplan as an automated training tool.

description: We present the initial data for the ($J = 3 \to 2$) transition of $^{13}$CO obtained from the Central Molecular Zone (CMZ) of the Milky Way as part of the CO Heterodyne Inner Milky Way Plane Survey 2 (CHIMPS2). Covering $359^\circ \leq l \leq 1^\circ$ and $|b| \leq 0.5^\circ$ with an angular resolution of 19 arcsec, velocity resolution of 1 km s$^{-1}$, and rms $T_A^* = 0.59$ K at these resolutions, our observations unveil the complex structure of the CMZ molecular gas in improved detail. Complemented by the $^{12}$CO CHIMPS2 data, we estimate a median optical depth of $τ_{13} = 0.087$. The preliminary analysis yields a median $^{13}$CO column density range equal to $N(^{13}\text{CO})= 2$--$5 \times 10^{18}$ cm$^{-2}$, median H$_2$ column density equal to $N(\text{H}_2)= 4 \times 10^{22}$ cm$^{-2}$ to $1 \times 10^{23}$ cm$^{-2}$.
 We derive $N(\text{H}_2)$-based total mass estimates of $M(\text{H}_2)= 2$--$6 \times 10^7\, M_{\odot}$, in agreement with previous studies. We analyze the relationship between the integrated intensity of $^{13}$CO and the surface density of compact sources identified by Herschel Hi-GAL, and find that younger Hi-GAL sources detected at 500 $μ$m but not at 70 $μ$m follow the dense gas of the CMZ more closely than those that are bright at 70 $μ$m. The latter, actively star-forming sources, appear to be more associated with material in the foreground spiral arms.

description: Aim: This study was conducted in three phases. Phase 1 aimed to adapt the Cancer Information Overload Scale and conduct content validity testing. Phase 2 aimed to conduct factorial validity testing of the scale. Phase 3 aimed to assess information overload and the sources of information used by nurses and midwives to keep up-to-date about COVID-19. Design: A cross-sectional survey of nurses and midwives working in a metropolitan Local Health District in Sydney, Australia, was conducted from May to June 2020. Methods: Adaptation of the Cancer Information Overload Scale and content validity of the modified scale (as the Pandemic Information Overload Scale) was undertaken by an expert panel comprising of senior nurses and researchers. Factorial validity and reliability of the Pandemic Information Overload Scale were evaluated using exploratory factor analyses using one subsample of the data. Using the second subsample of the data, information overload and sources of information used by nurses and midwives to keep up-to-date about COVID-19 were examined. Results: The Pandemic Information Overload Scale is a reliable and valid instrument for measuring information overload among nurses during a pandemic. Its internal consistency was high (α = 0.81, M = 3.84). Conclusion: The 8-item PIO scale is a brief, reliable and psychometrically sound instrument for measuring nurses' and midwives' perceptions of information overload during COVID-19. Mean scores across this study indicated that participants were experiencing above average information overload. Implementing strategies to reduce this overload would optimize clinical decision making and promote patient safety.

Laser nonlinearity compensation for subcarrier multiplexed optical transmission systems.
Creators: name: Tayebi, Niloufar.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1992
Subjects: subject: Engineering, Electronics and Electrical.

description: Subcarrier multiplexing efficiently uses the available fiber bandwidth in video transmission. Semiconductor lasers are usually used as optical transmitters in such systems. A semiconductor laser exhibits nonlinear characteristics. Nonlinearity degrades system performance. For nonlinearity compensation, a nonlinear predistortion block is assumed to be incorporated prior to the laser. Characteristics of this nonlinear block invert those of the laser. Performance of the subcarrier multiplexed system with and without predistortion is evaluated by harmonic distortion and intermodulation distortion analyses. Nonlinear distortion level decreases significantly when predistortion is employed prior to the laser. This enhancement results in system requirements for carrier-to-noise ratio being met.
A proposed approach to the analysis of computer program copyright infringement in Canada
Creators: name: Tait, David A
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2005
Subjects: subject: Law.

description: Canadian computer program copyright infringement decisions are' characterized by prolix reasoning and inconsistent methodological approaches. In this context, there exists a need for the explication of a revised approach to the analysis of infringement vis-a-vis production and reproduction rights. Herein the author explicates a proposed approach, which holds true to the dictates of the idea/expression dichotomy and the requirement of originality. It recognizes a difference between "copyrightable" and "protected by copyright" regarding parts of a computer program, rejects the U.S. abstraction-filtration-comparison test, allows a court to consider all admissible evidence when making the assessment of copying in fact, restrains the taking of parts of a computer program that in quality constitute original expression, and provides justification for the "weeding-out" favoured by the courts. The proposed approach provides a sound foundation for courts and lawyers to deal with issues looming on the litigation horizon as regards computer program copyright infringement.
Identification of Rho-associated protein kinase-alpha as an insulin receptor substrate-1 binding protein.
Creators: name: Farah, Sahar.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1998
Subjects: subject: Biology, Molecular.

description: Insulin receptor substrate-1 (IRS-1) is phosphorylated on multiple tyrosine residues by ligand-activated insulin receptor. These tyrosine phosphorylation sites serve to dock several SH2-containing signaling proteins. In addition, IRS-1 also contains several protein modules that have been implicated in protein-protein or protein-lipid interactions. In an attempt to identify novel proteins that may interact with these IRS-1 protein modules, yeast two-hybrid screening was employed. The bait, corresponding to the N-terminal 500 amino acids of the Xenopus IRS-1 (XIRS-1), was comprised of a pleckstrin homology (PH) domain, a phosphotyrosine binding (PTB) domain and a SAIN (Shc and IRS-1 NPXY binding) domain. Screening of a Xenopus oocyte cDNA library with the bait resulted in the isolation of a partial Xenopus cDNA, XROK$\alpha$. The cloned cDNA contains an open reading frame of about 500 amino acids (in frame with the N-terminal GAL4 activating domain) which are 90% identical to the C-terminus of the recently identified RhoA-associated protein kinase $\alpha$ (ROK$\alpha$). The partial XROK$\alpha$ cDNA contains the putative Rho binding domain as well as the C-terminal pleckstrin homology/cysteine rich domain (PH/CRD) but lacks the N-terminal serine/threonine kinase domain. Using the yeast two-hybrid system, we showed that XROK$\alpha$ interacts strongly with a constitutively active form of RhoA (V14-RhoA). Further analysis indicated that the XIRS-1 PTB domain is specifically involved in binding to XROK$\alpha$. To further characterize the potential role of XROK$\alpha$ in insulin signalling, I have cloned the entire coding sequence of XROK$\alpha$ by a combination of hybridyzation screening and PCR amplification. I have also generated XROK$\alpha$ specific polyclonal antibodies. Using these antibodies I have detected endogenous XROK $\alpha$ protein by both Western-blotting and by immune kinase assay in vitro. Taken together, these studies have identified an IRS-1 binding serine/threonine kinase which may play an important role in modulating insulin signalling.

description: Chamaecyparis formosensis is Taiwan’s most representative tree, and has high economic value. To date, only a few active chemical constituents have been reported for C. formosensis. In this study, 37 secondary metabolites, including three new compounds (1–3), were extracted from the leaves of C. formosensis. The compounds isolated from the ethyl acetate layer were used at different concentrations to treat HT-1080 human fibrosarcoma cells and to evaluate their effects on matrix metalloprotease 2 (MMP-2) and 9 (MMP-9) expression. Based on extensive analysis of data from high-resolution mass spectrometry (HR-MS) as well as nuclear magnetic resonance (NMR), infrared (IR), and ultraviolet (UV) spectroscopy, the new compounds were identified as 11,12-dihydroxyisodaucenoic acid (1), 12-hydroxyisodaucenoic acid (2), and 1-oxo-2α,3β-dihydroxytotarol (3). Known compounds 4–37 were identified by comparing their spectroscopic data with data reported in the literature. Biological activity tests by gelatin zymographic analysis revealed that seven compounds, including new compound 2, have no cytotoxic effect on HT-1080 cells and were found to increase MMP-2 or MMP-9 expression by 1.25- to 1.59-fold at lower concentrations of 10–50 µM. These naturally derived regulatory compounds could potentially serve as a novel pharmaceutical basis for medical purposes.
A new framework for self-disorders : anxiety as a case study
Creators: name: Jewell, Alexandra D.
Publisher: name: University of British Columbia
Year: 2025

description: Current conceptions of anxiety disorders often neglect the lived experience of individuals, resulting in an incomplete account of how anxiety alters both self- and world-experience. Taking first-person reports seriously and applying a phenomenological lens, this dissertation argues that anxiety disorders involve disruptions to the experiential core-self—the pre-reflective sense of being a bodily agent embedded in and capable of navigating the world. Specifically, I propose that anxiety disorders should be considered instances of self-disorders due to alterations in what I call the Felt-Reality System, a bodily-affective system responsible for conferring a sense of reality to objects and structuring one’s embedded agency. The Felt-Reality System not only underpins how individuals experience objects as real and co-spatial (here and now), but also plays a crucial role in constituting the pre-reflective sense of self—specifically, the embodied agential self embedded in a behaviorally-negotiable world. In cases of anxiety, this system undergoes breakdowns, producing an overwhelming sense that a threat is present here and now, disrupting the individual’s capacity to orient herself as an agent in behaviourally-negotiable world. Chapter 1 introduces the topic by reviewing existing research on anxiety, including its prevalence, treatment efficacy, and dominant explanatory models. In Chapter 2, I argue that Felt-Reality is a phenomenological feature of experience that implicitly shapes perception and action at the proto-noetic level. In Chapter 3, I consider ways the Felt-Reality System can breakdown and propose a novel conceptualization of anxiety as the Felt-Reality of threat, characterized by an overwhelming sense that a threat is present—even when it is neither here nor now—and a corresponding sense of the self as threatened. In Chapter 4, I argue that anxiety disorders include disruptions to an individual’s experiential core-self, the pre-reflective sense of being an agent in the world. On this view, anxiety disorders are instances of self-disorders, given the disruptions in the Felt-Reality System. This approach not only refines our understanding of anxiety disorders but also suggests novel therapeutic interventions. In Chapter 5, I conclude by advocating for phenomenological psychopathology that prioritizes lived experience, enabling more precise classifications and interventions in mental health.
Dll1 is a Potential CDX2 Target Gene

Subjects: subject: Biology, Molecular.

description: The functional redundancy and peri-implantation lethality inherent to members of the CDX family has traditionally limited their investigation. As such, the development by our lab of a conditional null mutant, obliterating CDX activity in the mouse, has opened up an exploration of their additional roles. Along with the loss of caudal tissue and failure of neural tube closure, Cdx1/2 null mutants exhibit abnormal somites, an observation which is echoed by the misregulation of many somitic players including members of the Wnt and Notch signaling pathways upon microarray analysis. The replication of altered expression patterns in situ and identification of consensus CDX response elements (CDRE) in the proximal promoter regions validated many of these genes as potential CDX targets. Characterization of one candidate in particular, DIl1, revealed reduced expression in the absence of CDX and overlapping expression domains with CDX members as well as somitic anomalies in Dil1 null mutants. The identification of two highly conserved putative CDRE in the proximal promoter region, in addition to the ability of CDX2 to occupy the promoter in the vicinity of these sites in vivo and specifically bind the identified motifs in vitro, was consistent with direct regulation. Functional analysis of CDX2 in association with the Dll1 promoter has so far proven inconclusive, but synergistic induction of the wildtype promoter in the presence of TBX6 supports a potential co-regulation. Overall, this thesis presents evidence for delta-like 1(Dll1) as a potential direct target of CDX2. Moreover, these findings support the possibility that CDX may regulate players in the Notch and Wnt signaling pathways and thereby play an important role in somitogenesis.

Subjects: subject: Religion, General.

description: This research is based on the examination of artifacts, specifically a series of artifacts known in Spanish as nichitos (little niches), found, among other places, in the Catholic Spanish speaking areas of Tucson, Arizona. Similar objects or constructions are also found in the Catholic Italian speaking communities of New York State and Missouri, and in the Catholic French Canadian communities of Quebec and Ontario, as well as in French speaking Louisiana. Nichito-like artifacts found in other cities, regions, and countries are included for the sake of comparison. The study of these artifacts is approached from an anthropological perspective, including ethnography, supplemented by folklore studies and informed by the multi-disciplinary context of religious studies. The research progresses through several phases. A classification of nichitos and nichito-like artifacts allows for definitions and contextualization of the artifacts themselves. Terms in Tucson Spanish are used for clarification and to establish a lexical norm for classification, as this community appears to have the most specialized collection of terms. An analysis of the context of the nichitos identifies the iconographical components of the artifacts. Religious and social aspects of nichito use are examined in the barrios of the Tucson area, leading to questions concerning religiosidad populare (popular religion) and the links or conflicts between domesticity and official religion.
To Investigate the Bacteria found on Children's Mouthguard

description: In contact sports, oral devices help prevent serious injury to the mouth. While they prevent injuries, they are prone to environmental contamination.
In this study, I have focused on isolating the most commonly occurring bacteria present on children’s mouthguards, cases, and the oral cavity prior to their usage. I have hypothesis that bacteria isolated on the mouthguard and respective cases have possibly been acquired from the external environment due to improper storage.
Furthermore, key criteria such as biofilm activity, surface roughness, SEM and water activity were studied to understand their attachment on mouthguard surface. Finally, I have focused on different cleaning techniques to suggest an effective way to minimize bacterial attachment.

description: Les théoriciens néoclassiques croient que la participation stratégique est spécifique au type innovateur, et absente dans les anciennes formes d'organisation. Cependant, cette distinction n'est pas flagrante. II existe encore aujourd'hui des traces de structures traditionnelles qui bloquent la participation des employés dans les organisations innovatrices. L'étude de cas suivante comprendra deux organisations innovatrices et une autre traditionnelle. Il est à noter que l'étude du niveau de participation, appuyée de questionnaires, d'entrevues et de données secondaires, est réalisée dans chacun des cas sous l'angle de l'autonomie, de l'influence et de l'intégration considérées comme des facteurs de la participation. Nous verrons que la participation n'est pas partagée uniformément entre les employés, souvent à cause d'un manque d'intégration de certains d'entre eux. Il n'est alors pas suffisant de l'estimer seulement par des configurations organisationnelles. Il faut mener l'analyse plus loin.
Behaviour of the adsorbed chloride intermediate in electrocatalysis of anodic chlorine evolution at oxide film surfaces at platinum and ruthenium.

description: In this thesis, the investigation of the mechanism of chlorine evolution reaction at (i) both freshly reduced and pre-oxidized Pt electrodes; (ii) RuO$\sb2$-TiO$\sb2$ electrodes (DSA); (iii) other noble metals such as Pd, Ir, Ru and Rh by means of computer controlled anodic polarization, potential-relaxation transients and a.c. impedance measurements, will be presented. As described in Chapter V, the influence of co-deposited OH and O species in the surface oxidation process on the extent of chemisorption of the Cl$\sp-$ intermediate in the Cl$\sb2$ evolution reaction has been carefully examined. Experimental results reveal that the reaction rate at reduced Pt surfaces is much greater than that at pre-oxidized ones. This is because the oxide species have a significant effect in blocking the Cl$\sb2$ evolution kinetics. The detectable surface adsorption pseudocapacitance, which is associated with the "overpotential deposited" Cl$\sp-$ intermediate, at freshly reduced Pt and oxide free Pt surfaces in non-aqueous trifluoroacetic acid (TFA) medium supports this conclusion. In Chapter VI, some exploratory experiments at other noble metal (e.g., Pd, Ir, Ru, and Rh) electrodes in non-aqueous TFA solution have shown very interesting interfacial capacitance information, which must be interpreted probably in terms of more than one adsorbed reaction intermediate being present. In Chapter VII, a possible mechanism of recombination kinetically control has been proposed for the Cl$\sb2$ evolution reaction at RuO$\sb2$-TiO$\sb2$ electrodes, based on the observations of their steady-state behaviour, and electrochemical data from potential relaxation and a.c. impedance measurements. Local supersaturation of Cl$\sb2$ in the microstructure of the oxide film appears to make a contribution to the pseudocapacitance behaviour.

The generation of this layer on the surface of an artificial graft could provide the necessary non-thrombogenic properties to the artificial prosthesis. In this work, synthetic cell adhesion peptides were designed, synthesized and chemisorbed onto the surface of a gold coated polyurethane. The polymer substrate was chosen in order to maintain good mechanical properties in the artificial vein or artery, while the gold coating served the purpose of permitting surface modification with the cell adhesion peptides. The peptides were custom designed to specifically be active to cell surface receptors on vascular endothelial cells. The peptides also contained a thiol present in a cysteine amino acid which was necessary for interaction with the gold on the polymer surface. The modifications to the surface were confirmed by various methods including water contact angles, and surface analysis techniques such as: x-ray photoelectron spectroscopy, atomic force microscopy and scanning electron microscopy. The surfaces were tested for their ability to promote the initial attachment of both vascular endothelial cells and mouse 3T3 fibroblasts. (Abstract shortened by UMI.)
Hacia una redefinición de la feminidad : proyecto social y discurso poético en Rosario Castellanos.

description: All Rosario Castellanos' work (1925-1974) reflects her vital concern: women and their historical relationship of subordination within the system of patriarchy that we can trace through different periods of history. In her varied production of poems, short stories, novels, plays and essays, Castellanos explored in particular the devices that from within the patriarchal logic have undermined women's being, making them develop dependent, unsatisfied subjectivities, always under male tutelage. Within this framework, this study analyses four of the later poems of Castellanos. Our interest is to see how in her quest for a re-definition of femininity, which still has resonance today, Rosario Castellanos seeks alternative ways to define the categories of female and male as traditionally determined by Western Social Imagination. An extensive critical bibliography already exists on Rosario Castellanos, and from the 80s onwards she has been studied more and more within the context of women's studies, gender studies and feminist theory. Some of these studies examine Castellanos' poetry from feminist viewpoints, but practically none of them concentrates exclusively on her poetry. This study attempts to partially fill that gap.

description: PILOT (the Pathfinder for an International Large Optical Telescope) is a proposed 2.5-m optical/infrared telescope to be located at Dome C on the Antarctic plateau. Conditions at Dome C are known to be exceptional for astronomy. The seeing (above similar to 30m height), coherence time, and isoplanatic angle are all twice as good as at typical mid-latitude sites, while the water-vapour column, and the atmosphere and telescope thermal emission are all an order of magnitude better. These conditions enable a unique scientific capability for PILOT, which is addressed in this series of papers. The current paper presents an overview of the optical and instrumentation suite for PILOT and its expected performance, a summary of the key science goals and observational approach for the facility, a discussion of the synergies between the science goals for PILOT and other telescopes, and a discussion of the future of Antarctic astronomy. Paper II and Paper III present details of the science projects divided, respectively, between the distant Universe (i.e. studies of first light, and the assembly and evolution of structure) and the nearby Universe (i.e. studies of Local Group galaxies, the MilkyWay, and the Solar System).
An asymmetric turbulent fluid flow induced by rectangular ribbed surface roughness.

description: The present thesis presents a theoretical as well as experimental investigation of fully developed turbulent fluid flow in partially roughened surfaces channel. The fluid properties wer assumed to be constant throughout the analysis. In the theoretical study of the problem the momentum integral method together with a turbulence model based on Prandtl's mixing length theory is adopted. The closure of the equations with one empirical constant was not possible and its was required to use empirical functions for the parameters describing the maximum velocity and zero shear stress points. The mean flow parameters of interests were given due considerations in the investigation. The experimental study involves the measurements of mean and turbulent characteristics of the flow in a partially roughened surfaced channel. The asymmetric flow between parallel planes was developed by roughening one of the planes with rectangular ribs while the other was left smooth. The most important parameters in the analysis are the locations of zero shear stress and maximum mean velocity points, since they are the main experimental inputs used in the prediction of mean flow parameters. The positions of the zero shear and maximum velocity points deviate more from the centre line of the channel towards the smooth wall for a lower roughness density as well as for increased Reynolds numbers corresponding to the same channel width.
Investigating the impact of self-as-a-model interventions on children's self-regulation of learning, swimming performance, and thought processes

description: This study compared the impact of a self-modeling intervention (viewing oneself perform an adaptive behavior) and practice, a self-observation intervention (viewing oneself perform at current skill level) and practice or practice alone on children's self-regulation of learning, anxiety, swimming performance and thought processes. A mixed methodology approach was employed as both qualitative and quantitative data were obtained. The quantitative component operated within Zimmerman's (1989, 2000) theory of self-regulated learning, and as such four self-regulatory processes (self-efficacy, motivation, self-satisfaction, and goal setting), as well as anxiety and physical performance were examined. For the qualitative component, the current study employed a think-aloud protocol (Ericsson & Simon, 1996) with the goal of understanding the thought processes that unfolded when children viewed self-modeling and self-observation videos. Thirty-three children, between the ages of six and ten (mean age = 8.3 years), were randomly assigned to a self-modeling group, a self-observation group or a control group. The children participated in an eight-day swimming intervention program. The analyses with the quantitative data showed consistently that the self-modeling group obtained superior scores on the measures examining the self-regulatory processes and physical performance as compared to both the self-observation group and the control group, with these two groups performing similarly. These results provide support for the implementation of self-modeling interventions with children learning motor skills. The analysis of the verbal protocols clearly showed that the majority of the children's verbalizations were self-evaluative in both a positive (Descriptive Positive), and negative (Descriptive Negative) direction, as well as, being related to future skill improvement (Prescriptive). These finding are discussed in terms of how they relate to Bandura's social cognitive theory of modeling (1977, 1986, 1997). A comparison revealed very few differences between the self-modeling and the self-observation interventions, suggesting that children appear to be gaining information about their skill performance and what to do to improve their next performance attempts regardless of the type of intervention.
Error control coding in ADSL DMT system.

description: Asymmetric Digital Subscriber Line (ADSL) is an access technology intended to provide up to 8 Mbps downstream digital transmission from the central office to customers and up to 640 kbps upstream transmission over the existing nonloaded copper loop plant. The transfer characteristics of twisted pairs make high-speed data transmission very difficult. Sharply increasing attenuation with the increase of frequency makes the higher frequency band unavailable for transmission and also gives very severe inter-symbol-interference (ISI). In ADSL, instead of using conventional single carrier transmission the preferred approach is to employ discrete multitone (DMT) transmission. The main idea of DMT is to change a high-rate transmit data sequence into some frequency-division multiplexed low-rate data sequences. With narrow-band subchannels, DMT systems can make much better use of the bandwidth and furthermore, it can solve the ISI problem in a simple way. In this thesis, a performance evaluation structure of RS codes in ADSL DMT systems against stationary noises (including additive-white-Gaussian noise (AWGN) and crosstalk noise) is designed.

Three dimensional finite element method applied to study the penetration of electromagnetic fields in cavities.

description: A three dimensional formulation of the finite element method was developed to solve the electromagnetic field distribution in an arbitrary region containing conducting and dielectric materials when the tangential magnetic field was known at the boundaries. The formulation was developed using a three component vector magnetic potential and a scalar electric potential. The displacement current as well as the conduction current term was accounted for. The region of interest was discretized using eight node isoparametric hexahedrons and the potential functions were defined using linear first order basis functions. The frequency domain finite element method program was validated by comparison with closed form solutions for simplified geometries. The algorithm proved to have a convergent solution when solving the diffusion of electromagnetic fields into conducting hollow and solid structures without apertures. The penetration of a steady-state electromagnetic field through an aperture into a simple cavity was analyzed with the 3-D FEM program. The diffusion of a step-impulse magnetic filed into a conducting slab was solved directly in the time domain with a time domain finite element program. Conclusions were drawn on the feasibility of using the finite element method as part of an EMI/EMC CAD package.

description: The new disaccharides, crystalline 6-deoxy-$\alpha$-D-gluco-heptopyranosyl 6-deoxy-$\alpha$-D-gluco-heptopyranoside (36) and the corresponding dicarboxylic acid (6-deoxy-$\alpha$-D-gluco-heptopyranosyluronic acid) 6-deoxy-$\alpha$-D-gluco-heptopyranosiduronic acid (5) were synthesized. Preparation of per-O- acetyl-$\alpha$,$\alpha$-trehalose 6,6$\sp\prime$-ditriflate 15 from known 2,3,4,2$\sp\prime$,3$\sp\prime$,4$\sp\prime$- hexa-O-acetyl-$\alpha$,$\alpha$-trehalose, followed by cyanide displacement in the former and subsequent hydrolysis produced 5. The latter was acetylated to give the 2,3,4,2$\sp\prime$,3$\sp\prime$,4$\sp\prime$-hexaacetate 12 of 5 which was reduced to furnish the disaccharide 36. This approach was also extended to synthesize the analogous 2,3,4,2$\sp\prime$,3$\sp\prime$,4$\sp\prime$-hexabenzyl ether of the dinitrile 28 which was similarly hydrolysed, but only to the stage of the corresponding diamide. The peracetylated dicarboxylic acid 12 was converted to the dichloride and subsequently esterified with 1-octanol, to form the di-octyl ester. Similar esterification with C$\sb $, C$\sb $, C$\sb $ and C$\sb $ 1-alkanols produced the analogous diesters. Three new mycolyl derivatives were obtained in high yields. (Abstract shortened by UMI.)
