Speech Prosody, Processing Effort, and the Detection of Syntactic Clause Boundaries by Adults with Cochlear Implants

description: Cochlear implants (CI) can be surgically implanted to restore hearing in individuals who can no longer benefit from hearing aids. However, the loss of spectral richness brought about by cell death and tonotopic mismatch from implantation makes processing speech more difficult – users often experience fatigue during everyday social situations, despite scoring well on listening tasks post-surgery. Listening is, therefore, differentially more effortful for CI users than normal-hearing individuals. The loss of spectral richness also causes degradation of pitch perception, which has caused current literature to claim that CI users have a prosody deficit. However, there is more to prosody than just pitch variation. In this thesis I use pupillometry as a physiological index of effort employed by 22 CI users during listening tasks in which I manipulated the prosodic markings of clause boundaries. I found that CI users are, in fact, able to perceive some features of prosody and to use prosody to facilitate recall of sentences when the prosody coincides with a syntactic clause boundary and is detrimental to recall when prosody and syntax conflict, thus countering claims that CI users are insensitive to prosody. I also found that word recognition ability predicted cognitive effort, but only for those with a word recognition score above 45% correct. I report two additional experiments with normal-hearing listeners designed to determine which features of prosody CI users might be utilizing to detect clause boundaries in comprehension of globally ambiguous sentences. This was done by selectively removing pitch, amplitude, and timing cues, using pupillometry to assess increases in processing effort as each prosodic feature was removed. Preliminary results show that individuals exert the most effort when timing cues (clause-final pauses and word-lengthening) are removed. Results are considered in the context of the FUEL model of effortful listening.

description: Seventeen Cree anti-diabetic medicinal plant were investigated for their capacity to cause adverse effects when used as alternative or complementary medicine. Two aspects of safety were studied using their extracts: the ability to affect the contraction rate of neonatal rat cardiomyocytes in vitro to determine if the plants can influence the human heart rate, and the ability to interfere with drug metabolism by inhibiting the cytochrome P450 enzymes in vitro. The results suggest that several Cree plants may cause a harmful effect through different mechanisms. The extracts ofW2, W4, W5, and W9 did not affect the contraction rate of cardiomyocytes; however W9 extract was cardiotoxic at 10 mug/mL. Extracts of AD01, AD07, W2, and W4 had moderate or strong inhibitory potency towards the CYP isoforms involved in metabolizing common anti-diabetic drugs. Furthermore, AD02 extract was identified as a possible CYP3A4 mechanism-based inhibitor. Overall, the results suggest that several of the plant species can cause adverse events when used by diabetic patients.

description: Fermented liquid pig manure (LPM) can be used as a nutrient source to replace synthetic fertilizers (SF). However, concerns remain regarding nitrogen (N) and phosphorus (P) losses from rice (Oryza sativa L.) paddies fertilized with LPM. Fly ash (FA) has a high calcium content (Ca) and zeolite (Z) has a high negative-charge; thus, they can immobilize P and N through the fixation of P with Ca and NH4+ onto negatively charged sites, respectively. This study investigated the effects of the co-application of FA and Z (FAZ) on the nutrient availability and growth of rice fertilized with LPM. Four treatments were evaluated: no input (control), synthetic fertilizer (SF), and LPM at two levels, with or without FAZ application, for 104 days. The pH (pHwater), electrical conductivity (ECwater), N (Nwater), and P (Pwater) concentrations in the ponding water of rice fields were analyzed 18 times during rice growth. The rice biomass and uptake of N and P were measured, and the concentrations of mineral N and available P in soil were determined after harvest. LPM application increased (p < 0.001) N and P availability in the absence of FAZ, leading to rice biomass comparable to that of SF. However, FAZ diminished the fertilization effects of LPM on rice growth. The Nwater decreased by 50% and the rice uptake of N increased by 6% after FAZ application, probably because of the retention of N by Z and its subsequent release. By contrast, FAZ increased (p < 0.001) soluble Pwater (85% for LPMS) and decreased (p = 0.004) P uptake (8%–40%), reducing the rice biomass by 20%–25%. The decreased P uptake is probably due to the strong immobilization of P by FA. Therefore, it is cautioned that P-limitation through immobilization of P by FA under alkaline conditions may hinder rice growth in FAZ-amended paddy fertilized with LPM. An appropriate application rate of FA for improved P nutrition needs to be explored.
Aboriginal representations in the Canadian news media: A socio-semiotic analysis of the media representation of Aboriginals in the Caledonia land dispute and of its relevance for the understanding of the identity of this group in Canadian society

description: This thesis addresses the issue of aboriginal representations in the Canadian Broadcasting Corporation (CBC) and Canadian Television (CTV) news coverage of the Caledonia land dispute. The theoretical framework derives from the scholarly work done in the field of media and minority studies. The methodology that will be used to address the issue of aboriginal representations in the media is a socio-semiotic analysis of news clips generated by the CBC and CTV. The medium of television was selected for analysis because of its reliance on sound and image to convey meaning, which allows for a visual and a conventional textual analysis of how the aboriginal identity is represented by the media coverage of aboriginal land claim disputes. The results of this study suggest a possible biased representation of the aboriginal identity, one which is primarily based on their status as a minority within Canada.

description: Food recipes, as a type of instructional text, contain series of instructions that guide human users\r through cooking processes. Their structures can usually be represented as flow graphs: at the start\r state, a collection of ingredients are introduced. Then, a series of actions are performed on these\r ingredients (along with cooking tools). Finally, the completed dish is produced at the end.\r A computer system that can extract such structures from food recipes can have many useful\r applications.\r Since food recipes are written by humans, they pose many of the same problems the field of\r Natural Language Processing is trying to solve. Furthermore, they also have challenges that are\r not commonly seen in many other types of texts.\r This thesis explores a Statistical Machine Learning approach to food recipe text processing. I\r will detail my work in the creation of an annotated food recipe dataset used in supervised learning.\r I will also describe my work in training Machine Learning algorithms that perform Named Entity\r Recognition and Relation Extraction tasks on this dataset.

description: This thesis examines the influence of municipal policy visioning initiatives on the transformation of industrial cities into cybercities. The emergence of the cybercity is mapped, and the role of municipal policy visioning initiatives in its development is examined. Two fields guide this research: communication and urban studies. The cybercity concept draws on both fields, and both are necessary to answer the research questions posed: How do municipal policy visioning initiatives influence a city's transformation into a cybercity? Montreal is used as a case study, and document analysis forms the core of the research strategy. Industry profile reports, government statistics and official organization websites provide supporting evidence. The policy visioning document examined supports the development of Montreal as a cybercity only where that development coincides with the city's development as a creative city. Improvements to future municipal policy depend on the inclusion of specific benchmarks that enable the effectiveness of policies to be measured.

description: Il giudeo-arabo è una varietà linguistica sorta nel corso dell’ottavo secolo come naturale conseguenza del contatto tra la cultura ebraica e quella arabo-islamica. Nonostante questa varietà per la sua natura poliedrica attiri l’interesse di studiosi di diverse discipline, il suo studio non è contemplato ad oggi in nessuna università italiana. In questo lavoro si rifletterà sulla possibilità di insegnamento di questo idioma, e, ipotizzando un percorso didattico dedicato a discenti arabisti, si rifletterà sugli eventuali strumenti didattici che risulterebbero maggiormente efficaci in base alle peculiarità più rappresentative di questo etnoletto.

description: Research on the identification of human skeletal remains, though abundant, lacks a centralized methodology that accounts for population-specific variations in the timing of epiphyseal fusion in subadults. The most depended-upon methods of skeletal aging yield varying results. By building a compendium of these studies’ findings and exploring how they were reached, researchers may be able to better understand how to interpret their own results within the context of their source populations. In the process, overlaps and discontinuities in age estimations across methods may be used to begin tailoring a global standard for skeletal identification that can be performed irrespective of region or ancestry. Investigation into the populations of origin used by major methodological sources (namely, works published by Flecker (1942), McKern & Stewart (1957), Paterson (1929), Stevenson (1924), and Webb & Suchey (1985)) would enable a clearer understanding of variations in human skeletal traits and aging patterns on a population level.

description: Herein, the antibacterial, antifungal and antiviral activities of Astragalus spinosus leaves, the largest genus in the family Fabaceae, were evaluated. Forty compounds were identified from the hydroalcoholic plant extract using the LCMS/MS technique. The identified candidates were chemically divided into hydroxycinnamic acid derivatives, flavonoids, and their glycosides. The hydroalcoholic extract showed potent antibacterial activity against Bacillus cereus, Klebsiella pneumoniae, and Pseudomonas aeruginosa with MIC between 5 and 10 mg/mL. Moreover, the extract exhibited a considerable antiviral effect against HSV-2 (IC50 = 57.9 µg/mL). Molecular docking studies were performed to get insights into the different binding poses of the identified candidates toward either the MATE or HSV-1 target receptors. Compounds kaempferol-O-rutinoside and isorhamnetin-O-rutinoside showed superior activity against the MATE receptor, however, isorhamnetin-O-rutinoside and rutin-7-O-hexoside achieved the best binding toward the HSV-1 receptor. The stabilities of the best compounds inside the active pocket were investigated using MD simulation and the MM-GBSA binding energies for the studied complexes were also calculated and compared to the native ligands. Kaempferol-O-rutinoside and isorhamnetin-O-rutinoside showed similar binding energies to the co-crystal ligand of the MATE multidrug efflux pump with MM-GBSA energy of −83.94 and −82.27 kcal/mol, respectively. However, isorhamnetin-O-rutinoside, and rutin-7-O-hexoside showed superiorities over the co-crystal ligands of HSV-1 thymidine kinase by almost 20 and 13 kcal/mol, respectively.
Agricultural NGO's and their participation in the soil erosion and water quality management problem, in Ontario.

Subjects: subject: Agriculture, Agronomy.

description: The purpose of this research is to describe and analyze the present and potential role of non-governmental organizations (NGO's) in the management of agricultural soil erosion and associated water quality decline (ASEWQ), in Ontario. A series of five tasks are associated with this research purpose. These tasks include: the cataloguing of all agricultural NGO's in Ontario; the assessment of this NGO population's vertical interaction; the assessment of the NGO population's horizontal spread; analysis of NGO mobilization potential in the area of ASEWQ management; and finally the characterization of degree of NGO favourability towards, and involvement in, ASEWQ management. Research has led to the discovery of a very large and complex population of agricultural organizations in Ontario. The horizontal distribution of this population closely reflects the geographic configuration of agricultural activity in the province. The vertical distribution reveals a high degree of organizational affiliation and networking which gives the grassroots indirect access to provincial policy influence. Despite the size, complexity and general favourability of this population towards soil conservation, few NGO's have suitable potential to mobilize on the ASEWQ issue. As a result, only a few strategically placed and organized NGO's have any involvement in controlling agricultural soil erosion. In conclusion, this research offers a series of recommendations to provincial government agricultural policy makers and future research avenues. (Abstract shortened by UMI.)

description: As of 1999, only 36 instances of individuals with both Down syndrome and Autism Spectrum Disorder (DS-ASD) were described in the medical literature. Many conflating factors presumably delayed or prevented the accurate diagnosis of DS-ASD at the time, though the most striking barrier was a persistent belief in the medical community that the two conditions did not or could not coexist. Extensive work exists delineating the nature and impact of parental stress when a child is born with either Down syndrome or Autism Spectrum Disorder. Within these studies, cohorts of parents of children with either disability are frequently compared to each other, yet investigations into the experience of parents of the dually diagnosed are absent. We interviewed six parents to better understand the diagnostic process and the challenges and joys involved when raising a child with DS-ASD. We coded interviews in ATLAS.ti (version 7.0) and analyzed for themes. We found that parents were usually the ones to suggest their child had autism and most were able to find information about the dual diagnosis from either their doctor or their own Internet research. While the diagnosis of Down syndrome often came as a shock, the autism diagnosis brought a sense of validation to parents who had noticed differences in their child for years. Five of the six parents expressed feelings of alienation from parent or child groups that focused on solely one diagnosis. The formal diagnosis of autism created access to new services, though utilization varied. This study suggests the importance of accurate, timely diagnosis and appropriate support services for child and family.
Increasing incidence of cancer of the corpus uteri in the elderly in Canada? Analysis of descriptive data, hysterectomy adjustment and chart review.

description: Incidence of cancer of the corpus uteri (of which 89% is endometrial adenocarcinoma) in Canada is declining in women under 70 years of age; in women 70 and over incidence increased from 1969 until 1982 since when it has been stable. These incidence data use as a denominator all women in the population, rather than just women with intact uteri, who constitute the real population at risk. A descriptive analysis was done using data from national databases on incidence, mortality, morphology, method of diagnosis, surgical procedures and population numbers, focussing on incidence in women $\ge$70 years of age. A variety of models for the hysterectomy adjustment all resulted in a trend of increasing incidence in women over 70 years of age; this effect is most important in the most recent period, where the adjustment changes stable crude rates into increasing adjusted ones. Decreasing proportions of diagnosis by death certificate only, and decreasing mortality/incidence ratios in recent periods suggest some improvement in diagnosis in elderly women. Incidence of cancer of the corpus uteri, adjusted for hysterectomy prevalence, is increasing in women over 70 years of age in Canada. There is a cohort effect which may represent residual increased risk from unopposed estrogen use in the 1970s. There is also some (weak) evidence to suggest improved diagnosis of this cancer in elderly women in recent periods. Absolute numbers of cases in women $\ge$70 years are definitely increasing as the population ages. (Abstract shortened by UMI.)
The effects of heavy vehicle single, tandem and tri-axles on sprayed seal wear in Australia

description: Freight efficient vehicles today introduce significantly more tandem, triaxle axle and quad axle group loadings to pavement surfacings. However, the effects of differing axle groupings and axle loadings has never been thoroughly considered in sprayed seal design, because these effects had not been isolated and studied.
A model has now been develop to predict surface texture deterioration based on the effect of axle groupings and loadings. This generalised model could contribute to a refinement of sprayed seal design, specifically in the category of heavy vehicle seal design. The results may be used to improve the consideration of abnormal traffic affects in seal design of mine haul roads, or national freight routes.
Towards a practical and secure biometric authentication system

description: The idea of merging biometrics technology with cryptography brought interesting possibilities in enhancing the security and privacy of biometrics systems. Conventional systems generally require large databases, which represent a security risk and raise privacy concerns. Biometric encryption is a method devised to hide biometric features along with a cryptographic key, which could remove the need for such biometric databases. The Fuzzy Vault scheme is one of the promising candidates for biometric encryption. This thesis analyzes the scheme and attempts to provide solutions to problems impeding the system from being used in practise. We looked at the current techniques in dealing with the noise inherent in biometric templates, in particular fingerprints, and provides insight on their implication in information and biometric security. We also present two practical decoders based on the Berlekamp-Massey algorithm and the Euclidean algorithm, and provide the first implementation of a Reed-Solomon decoder for the Fuzzy Vault scheme. Our implementation results indicate that the traditional Berlekamp-Massey algorithm may not be as suitable and efficient as Gao's Reed-Solomon decoder. In our analysis, some potential vulnerabilities were also identified. In particular, the collusion attack was found to be able to seriously reduce the security of the scheme in practise and is applicable to all existing implementations. Some possible defenses against the attack such as a one-way transform of the locking set and deterministic chaff points generation were proposed.

description: This work focuses on medical pluralism in Peru. Looking at the use of traditional medicine in Peru both in the rural and in the urban sectors, but looking specifically at the collaboration of the two, as can be seen in the case of the reduction of maternal mortality. The issues that Peru must confront in regards to the use of modern medicine and traditional medicine rely heavily on greater integration and cultural pluralism in order for there to be greater understanding and collaboration between traditional medicine and biomedicine. This work looks at the benefits that have come out of medical collaboration with a focus on maternal health and the impact the international community has had on these benefits. This work also recommends action to be taken in order to completely integrate the indigenous people as part of the greater Peruvian nation, specifically focused on Health.

description: Burnout is defined by emotional exhaustion, depersonalization and reduced personal accomplishment. While it is known that genetic counselors are at moderate-to-high risk for burnout, there is limited data that identifies specific predictors of burnout in clinical genetic counselors to assist in determining those most at risk. The purpose of this study was to measure the level of burnout in practicing clinical genetic counselors, identify work-related predictors of burnout, and investigate the relationship between counselor burnout and thoughts of leaving their current job. A sample of 367 practicing clinical genetic counselors recruited through the NSGC listserv completed an anonymous, online survey containing the Maslach Burnout Inventory-Human Services Survey and questions about demographic and employment characteristics, social support, workload, and thoughts of leaving their current job. Results indicated that 52.9% of genetic counselors experience moderate-to-high levels of burnout. Ordinal logistic regression analysis yielded several significant predictors of burnout including low levels of social support (p<.001), greater workload (p=.027), younger age (p<.001), and marital status (p=.033). Chi-square analysis showed that burnout and thoughts of leaving current job were significantly associated (p<.001). The results confirm that clinical genetic counselors continue to be at risk of burning out, while also providing new insights into work-related predictors of burnout. These findings convey important target areas that may be integral to a genetic counselors’ professional well-being, including receiving adequate social and administrative support. Attention to these factors are likely to reduce the risk of burnout and prevent clinical genetic counselors from leaving clinical practice.
The "undesirables": Canadian deportation policy and its impact on female immigrants, 1946--1956

description: This dissertation examines female immigrants who were targeted for deportation after the Second World War. The women documented in this study include a broad array of immigrants who came to Canada from different locales such as Europe, the Caribbean and the United States. They were also quite divergent in terms of their class and racial backgrounds and experiences during and after the war. The only thing they shared, was that they were targeted for deportation by the federal Immigration Branch. Relying on 376 deportation case files from the Library and Archives of Canada---along with many other types of sources---this study delves into the diverse experiences of these women and attempts to piece together their treatment by the state as well as responses to the deportation process. As non-citizens, I argue, they did not have the resources and rights that Canadians enjoyed. Consequently, female immigrants who committed an offence under the Immigration Act were vulnerable to deportation and could not rely on the court system to protect them. Furthermore, this study illustrates that these women's experiences were different than those of Canadian women as well as their male counterparts. As such, regardless of the fact that the Immigration legislation appeared somewhat gender neutral, female immigrants were charged with different offences and subject to different standards than male immigrants, when the immigration officials were adjudicating their cases. The female immigrants in this study were typically convicted of offences under the Immigration Act relating to mental and physical health problems, moral charges, indebtedness and dependency. While these types of crimes were not included in the Criminal Code of Canada, they were an integral part of the Immigration Act, and female aliens who violated them, were typically reported, interrogated, regulated, and deported for committing these offences. Most of the women had no option but to submit to the deportation process and cooperate with the department's attempt to expel these female immigrants from Canada and return them to their homelands. There were, however, some women who fought back; a few disappeared, others refused to testify or sign the deportation order, and finally, a very small number challenged their cases all the way to the superior courts. Consequently, not all were victimized by the state.
Isolation, Purification, and Characterization of (+)-4R-limonene synthase: The first step in exploring enzyme stereospecificity in terpenoid biosynthesis
Creators: name: Olsen, Sarah Naomi
Publisher: name: Brandeis University
Year: 2011

description: Scientists have long marveled at the structural diversity of terpenoids and have speculated on its biosynthetic basis. Limonene synthase is often considered a model enzyme for terpenoid formation since it catalyzes the mechanistically simplest cyclization reaction. In this study, we attempt to address the question of how this class of enzymes achieves its regio- and stereospecificity, by supplementing previous studies on (-)-4S-limonene synthase with studies on (+)-4R-limonene synthase. Comparative structure and function analyses of these two enzymes, catalyzing the formation of the enantiomeric products (-)- limonene and (+)-limonene, respectively, will shed new light on differences in structural features and how these can direct stereoisomeric outcomes. Our study is the first to report successful isolation and functional expression of (+)-4R-limonene synthase from Citrus sinesis. We furthermore showed our clone to be enzymatically active, albeit with a higher Km than previously reported for other monoterpene synthases. Although various problems with our expression and purification protocol need to be addressed before crystallization trials can be set up, the isolation of an enzymatically active clone from orange tissue represents meaningful progress towards the ultimate goal of determining structural features that provide a mechanism for the skeletal diversity so characteristic of this class of enzymes.

description: Elite athletes use mental strategies in a wide variety of sports to enhance performance (Mahoney, Gabriel, & Perkins, 1987; Orlick & Partington, 1999; Schomer, 1987; Tammen, 1996; Ungerleider & Golding, 1991). High-level athletes have been found to use mental strategies before, during, and after competition (Orlick, 2000). Little is known, however, about the psychological strategies that Ironman triathletes use to race successfully. The question of how these triathletes mentally prepare to be their best in competitions has not been addressed in the literature. The purpose of this study was to explore the mental skills employed by elite Ironman triathletes by exploring the following research question: How do elite Ironman triathletes get themselves mentally ready to be their best during competitions? The present study provides meaningful insight into how elite Ironman triathletes mentally prepare. The main areas addressed include detailed race planning, following personal routines, focusing, controlling discomfort and other distractions, dealing with nutrition, having confidence in one's abilities, using imagery, staying positive, and connecting with one's body.
Ezras Noshim and Unruly Bodies: Disciplining Sexual Behavior of Jewish Immigrant Women in Argentina in 1936

description: This thesis is the first-ever analysis of eighteen cases related to Jewish immigrant women who came to Argentina from Eastern Europe (mainly Poland), and who, in 1936, came to the attention of Ezras Noshim, a Jewish organization in Buenos Aires. Prompted by complaints from the community that the women’s behavior violated social norms, Ezras Noshim staff recorded details of the life situations of these women, and took a variety of actions in response to “tame” and “civilize” their behavior. Data from Ezras Noshim’s 1936 annual report have been collected from La Fundación IWO (Institute for Jewish Research) in Buenos Aires and The Central Archives for the History of the Jewish People (CAHJP) in Jerusalem. Complaints about the women relate to crime and prostitution, to physical abuse, and to husband abandonment. The cases reflect Ezras Noshim’s understanding of the female psyche, body, and sexuality through a framework that defined the women’s behaviors and responses to their circumstances as social and medical pathologies. The women’s problems were subjected to scientific study and their bodies were disciplined by the state of Argentina, physicians, psychiatrists and Ezras Noshim’s members. Often the women were determined to be “mentally ill” and committed to mental hospitals. Through close readings of these case studies we can gain insights into the organized Jewish community’s understanding of these immigrant women’s behaviors, and their attempts to “civilize” them. We can also hear the echoes of the women themselves—managed by pimps and madames, coping with pregnancy and separation/abandonment from their husbands, and sometimes simply expressing a desire for their own physical and sexual freedom. Throughout the thesis, we can observe a moral agenda and a civilizing mission of Ezras Noshim that valued primarily the sexual purity and honor of Jewish women. And in these eighteen case reports, we can also read the challenges of immigrant women’s experiences, and the differing understandings of the women’s situations, sexualities, bodies, and mental health between the medical and organized Jewish community, and the immigrant women themselves.

description: The objective of testing is to determine whether an implementation under test conforms to its specification. In distributed test architectures involving multiple testers, this objective can be complicated by the fact that testers may encounter problems relating to controllability and observability during the application of a checking sequence. A controllability problem, also known as a synchronization problem, exists when a tester cannot determine when to send a particular input to the IUT. An observability problem exists when a tester cannot determine whether a particular output has been received from the IUT in response to the related input in the specification. Solutions in the literature to these problems generally require either appending additional input-output sequences or the use of external coordination messages between testers. This thesis proposes two methods for constructing checking sequences with no potential controllability and observability problems. The first method assumes the presence of a reliable reset in the implementation and constructs digraphs to facilitate the construction of state and transition cover subsequences. A Rural Chinese Postman Path on the final digraph constructed by the method yields a synchronizable ordering of these subsequences. The second method does not require a reliable reset and constructs digraphs to generate subsequences that verify each state and transition. An Euler Tour of the final digraph constructed by the method yields a checking sequence. In both methods, by considering controllability and observability problems during the construction of the checking sequence, the use of coordination messages is either minimized or, if possible, avoided altogether.

description: In direct hydrocarbon fuel cells, a hydrocarbon fuel is oxidised in the anode electrode. This thesis presents a mathematical model to predict the performance of a unit cell that utilises propane as the fuel, oxygen as the oxidant, phosphoric acid as the electrolyte, and platinum as the catalyst, supported on porous carbon electrodes. The phenomena considered include the electrochemical reactions of propane oxidation and oxygen reduction on platinum, the diffusion of the gases in gas-filled electrode pores, the dissolution and diffusion of dissolved gases in liquid-filled electrode pores as well as ionic conduction of protons. The model was based on the multi-layered physical structure of a modern unit fuel cell. The model was first applied to a phosphoric acid fuel cell cathode electrode. Subsequently, the model was applied to a direct propane-oxygen cell. (Abstract shortened by UMI.)

description: This thesis describes a practical formal approach to designing Internet (IP) Telephony services with fewer feature interactions using SDL and Message Sequence Charts (MSC). Feature interactions are undesirable side effects caused by interactions between features and/or their environment. These undesirable side effects are known to affect the construction of reliable software systems. The IETF 'Session Initiation Protocol' (SIP) is chosen as the IP telephony signaling protocol for the case study of this thesis. Although IP Telephony services do not have some of the traditional feature interactions, the service designers are confronted with new feature interaction problems. We have proposed an extension to the classical feature interaction classification system. The main contribution of this thesis is our formal SDL model of SIP and its sample services that are derived from informal SIP specification. We apply use case analysis to some informal extent in our design, and specify SIP services more precisely by creating an "Abstract User interface". (Abstract shortened by UMI.)

description: A comprehensive research project was conducted to investigate the behaviour and design of earthquake resistant normal-strength and high-strength concrete columns. The project included three essential components; testing of full size columns, development of an analytical model, and development of a design procedure. The experimental program consisted of material research and structural testing. The first phase was designed to study mechanical properties of high-strength concrete, which involved testing of a large number of concrete cylinders. The second phase was designed to investigate performance of confined normal and high-strength concrete columns under concentric compression. The experimental program included tests of 46 full size square and circular columns, with concrete strength ranging between 60 MPa and 124 MPa. The parameters considered included; cross-sectional shape (circular and square), volumetric ratio and spacing of transverse reinforcement, distribution of longitudinal reinforcement and resulting tie arrangement, yield strength of transverse reinforcement, concrete compressive strength, influence of longitudinal reinforcement in circular columns, and type of circular reinforcement (continuous spiral and circular hoops). The analytical component of the research program involved development of a mathematical model to represent stress-strain relationship of confined concrete. This was done in two steps. The first step included formulation of the relationship for normal strength concrete, for which extensive test data was available. The second step involved modification of the model for high-strength concrete. An extensive literature survey was first conducted, followed by evaluation of previous test data. This information was used, along with the results of the experimental phase of this investigation to develop a generalized cofinement model for normal-strength and high-strength concrete columns. The analytical and experimental research was used in developing a design procedure for confinement of earthquake resistant concrete columns. The procedure includes all the relevant parameters of confinement that have been observed to be important in column tests, and relates the design variables to deformation capacities. A displacement based design methodology was developed, where the lateral drift demand is a design parameter. This approach leads to different confinement steel requirements for columns with different deformability demands, an approach currently lacking in practice. Furthermore, the reinforcement arrangement is recognized as a design parameter, allowing lower volumetric ratio of confinement reinforcement for efficient arrangements. This may result in significant savings in steel, eliminating the common problem of steel congestion in earthquake resistant columns. (Abstract shortened by UMI.)

description: The partitioning of methyl mercury (MeHg) to dissolved organic carbon (DOC) and the photodegradation of mercury by UVB radiation (280-320nm) are two important processes that influence the availability of MeHg to the base of the aquatic food chain. Water samples from 20 sites across Eastern Ontario and Western Quebec were filtered sequentially using tangential flow ultrafiltration to determine the size distribution of MeHg and DOC and to test whether the concentrations and distribution of these two variables varied in wetlands, lakes and rivers. These filtrates were also analyzed for DOC fluorescence and absorbance. The highest proportions of mean MeHg (47.3 +/- 25.4%), DOC (56.8 +/- 14.5%) and DOC FL (74.5 +/- 11.4%) were found in the low molecular weight fractions (<5 kDa). Significant differences in the distribution and concentration of MeHg amongst filtered samples were found between wetlands, lakes and rivers. MeHg was related to DOC at all size fractions. The low molecular weight organic compounds may be an important contributor to MeHg biomagnification through uptake by bacteria and/or algae. St. Lawrence river water was collected to test factors that affect the rate of photodegradation of MeHg. Samples exposed to UVB irradiance from a fluorescent lamp and spiked with MeHg(5 ng/L) illustrated significant decreases in concentration with a 31% average loss after 6 hours. No significant difference in photodegradation was found between samples with and without added Fe(II). MeHg concentrations decreased 35.4% and 41.7% after 6 hours of exposure at pH 3 and 5, respectively. It appears that photo-demethylation is a function of UVB exposure, is more rapid in acidic conditions and likely occurs slower under most natural freshwater conditions due to the attenuation of UVB.
