- Abstract:
- Developing applications for touch devices is hard. Developing touch based applications for multi-user input is harder. The Multi-Touch for Java (MT4j) toolkit supports developing touch based applications for multiple users. In this paper, we outline our experience using MT4j for developing a number of software applications to support developers working in co-located teams. Our experience using the toolkit will help developers to understand the nuances of the toolkit and design issues that can be applied to other toolkits for developing multi-user touch based applications.

- Abstract:
- The aeronautics industry is looking for ice protection systems consuming less energy. Electromechanical and especially piezoelectric solutions are a promising area of research for reducing average consumptions. This article provides an analytical model of a simple structure to assess the power and voltage required to obtain the delamination of the accumulated layer of ice at the support/ice interface. This model also allows analyzing the impact of the resonance frequencies used for supplying piezoelectric actuators on the tensile stress into PZT materials. Finally, this article assesses the effect of different ice - phobic coatings combined with piezoelectric ice protection systems. Experimental measurements of ice adhesion for different ice - phobic coatings allow evaluating the shear stress at which ice is detached from the surface. These results are then used to estimate - thanks to the proposed analytical model - the additional gain of power that would be provided by the use of such coatings.

- Abstract:
- It has been observed in the literature that as the cardinality of the prescribed discrete input-output data set increases, the corresponding four-bar linkages that minimise the Euclidean norm of the design and structural errors tend to converge to the same linkage. The important implication is that minimising the Euclidean norm, or any p-norm, of the structural error, which leads to a nonlinear least-squares problem requiring iterative solutions, can be accomplished implicitly by minimising that of the design error, which leads to a linear least-squares problem that can be solved directly. Apropos, the goal of this paper is to take the first step towards proving that as the cardinality of the data set tends towards infinity the observation is indeed true. In this paper we will integrate the synthesis equations in the range between minimum and maximum input values, thereby reposing the discrete approximate synthesis problem as a continuous one. Moreover, we will prove that a lower bound of the Euclidean norm, and indeed of any p-norm, of the design error for planar RRRR function-generating linkages exists and is attained with continuous approximate synthesis.

- Abstract:
- The Maximum Likelihood (ML) and Bayesian estimation paradigms work within the model that the data, from which the parameters are to be estimated, is treated as a set rather than as a sequence. The pioneering paper that dealt with the field of sequence-based estimation [2] involved utilizing both the information in the observations and in their sequence of appearance. The results of [2] introduced the concepts of Sequence Based Estimation (SBE) for the Binomial distribution, where the authors derived the corresponding MLE results when the samples are taken two-at-a-time, and then extended these for the cases when they are processed three-at-a-time, four-at-a-time etc. These results were generalized for the multinomial “two-at-a-time” scenario in [3]. This paper (This paper is dedicated to the memory of Dr. Mohamed Kamel, who was a close friend of the first author.) now further generalizes the results found in [3] for the multinomial case and for subsequences of length 3. The strategy used in [3] (and also here) involves a novel phenomenon called “Occlusion” that has not been reported in the field of estimation. The phenomenon can be described as follows: By occluding (hiding or concealing) certain observations, we map the estimation problem onto a lower-dimensional space, i.e., onto a binomial space. Once these occluded SBEs have been computed, the overall Multinomial SBE (MSBE) can be obtained by combining these lower-dimensional estimates. In each case, we formally prove and experimentally demonstrate the convergence of the corresponding estimates.

- Abstract:
- This paper deals with the relatively new field of sequencebased estimation which involves utilizing both the information in the observations and in their sequence of appearance. Our intention is to obtain Maximum Likelihood estimates by “extracting” the information contained in the observations when perceived as a sequence rather than as a set. The results of [15] introduced the concepts of Sequence Based Estimation (SBE) for the Binomial distribution. This current paper generalizes these results for the multinomial “two-at-a-time” scenario. We invoke a novel phenomenon called “Occlusion” that can be described as follows: By “concealing” certain observations, we map the estimation problem onto a lower-dimensional binomial space. Once these occluded SBEs have been computed, we demonstrate how the overall Multinomial SBE (MSBE) can be obtained by mapping several lower-dimensional estimates onto the original higher-dimensional space. We formally prove and experimentally demonstrate the convergence of the corresponding estimates.

- Abstract:
- In this paper, we propose a novel online classifier for complex data streams which are generated from non-stationary stochastic properties. Instead of using a single training model and counters to keep important data statistics, the introduced online classifier scheme provides a real-time self-adjusting learning model. The learning model utilizes the multiplication-based update algorithm of the Stochastic Learning Weak Estimator (SLWE) at each time instant as a new labeled instance arrives. In this way, the data statistics are updated every time a new element is inserted, without requiring that we have to rebuild its model when changes occur in the data distributions. Finally, and most importantly, the model operates with the understanding that the correct classes of previously-classified patterns become available at a later juncture subsequent to some time instances, thus requiring us to update the training set and the training model. The results obtained from rigorous empirical analysis on multinomial distributions, is remarkable. Indeed, it demonstrates the applicability of our method on synthetic datasets, and proves the advantages of the introduced scheme.

- Abstract:
- The field of game playing is a particularly well-studied area within the context of AI, leading to the development of powerful techniques, such as the alpha-beta search, capable of achieving competitive game play against an intelligent opponent. It is well known that tree pruning strategies, such as alpha-beta, benefit strongly from proper move ordering, that is, searching the best element first. Inspired by the formerly unrelated field of Adaptive Data Structures (ADSs), we have previously introduced the History-ADS technique, which employs an adaptive list to achieve effective and dynamic move ordering, in a domain independent fashion, and found that it performs well in a wide range of cases. However, previous work did not compare the performance of the History-ADS heuristic to any established move ordering strategy. In an attempt to address this problem, we present here a comparison to two well-known, acclaimed strategies, which operate on a similar philosophy to the History-ADS, the History Heuristic, and the Killer Moves technique. We find that, in a wide range of two-player and multi-player games, at various points in the game’s progression, the History-ADS performs at least as well as these strategies, and, in fact, outperforms them in the majority of cases.

- Abstract:
- The practitioner interested in reducing software verification effort may found herself lost in the many alternative definitions of Graphical User Interface (GUI) testing that exist and their relation to the notion of system testing. One result of these many definitions is that one may end up testi ng twice the same parts of the Software Under Test (SUT), specifically the application logic code. To clarify two important testing activities for the avoidance of duplicate testing effort, this paper studies possible differences between GUI testing and system testing experimentally. Specifically, we selected a SUT equipped with system tests that directly exercise the application code; We used GUITAR, a well-known GUI testing software to GUI test this SUT. Experimental results show important differences between system testing and GUI testing in terms of structural coverage and test cost.

- Abstract:
- UML diagrams describe different views of one piece of software. These diagrams strongly depend on each other and must therefore be consistent with one another, since inconsistencies between diagrams may be a source of faults during software development activities that rely on these diagrams. It is therefore paramount that consistency rules be defined and that inconsistencies be detected, analyzed and fixed. The relevant literature shows that authors typically define their own UML consistency rules, sometimes defining the same rules and sometimes defining rules that are already in the UML standard. The reason might be that no consolidated set of rules that are deemed relevant by authors can be found to date. The aim of our research is to provide a consolidated set of UML consistency rules and obtain a detailed overview of the current research in this area. We therefore followed a systematic procedure in order to collect and analyze UML consistency rules. We then consolidated a set of 116 UML consistency rules (avoiding redundant definitions or definitions already in the UML standard) that can be used as an important reference for UML-based software development activities, for teaching UML-based software development, and for further research.

- Abstract:
- Every year, for over three decades, Carleton University in Ottawa, Ontario has participated with other local educational institutions in providing a week-long instruction program that introduces young students to higher education. Highly motivated participants in grades 8 – 11 and numbering over 3,000 attend from several school boards in both eastern Ontario and western Quebec. The Enriched Mini Course Program has become an important recruitment tool for each institution, and at Carleton University, over 50 enriched mini courses are offered including one recent addition by the MacOdrum library staff. In this article, the author recounts how leading an enriched mini course for millennials in the university library's new Discovery Centre is an innovative initiative that demonstrates the significance of the academic library in the local community, and how staff collaboration helps to develop team building and positive vibes with the millennials.

- Abstract:
- “The first volume of Documents on Canadian External Relations was published in 1967, as Canada celebrated its first century of nationhood. Since then, volumes in this series have dealt with various periods in the history of Canadian foreign policy, from the Laurier era up to the Pearson years in government. The series currently includes 29 regular volumes and has reprinted over 20,000 documents, totalling almost 40,000 pages of text, making it the largest historical documentary project in Canada. The subject of this special volume, the Arctic, has an ever-growing importance for Canada as we approach our federation's 150th anniversary. This volume illuminates how and why Canada asserted its sovereignty over the Far North between 1874 and 1949, and it demonstrates how much Canadians today owe to the nation builders of the past”--Preface, p.

- Abstract:
- The Iowa Gamb ling Task (IGT) is widely used to assess the role of emotion in decision making. However, there is only indirect evidence to support that the task measures emotion. There are inconsistencies in performance within in healthy populations who display risk tak ing traits. Two hundred and fifty participants were assessed for psychopathy, sensation seeking, and impulsiveness. The IGT was compared with modified versions that directly manipulated emotion within in the task by indexing reward and punishment cards wit h images varying in emotional content. Participants continued to learn to avoid risky decks in all versions of the IGT. The manipulation of emotional content within the task did affect performance: fearful images contributed to greater risky deck selection s. Across the tasks, psychopathy showed the strongest relationship to risky deck selections, and lower levels of psychopathy was associated decreased risky deck selections. However, psychopathy did not affect learning in the modified versions. Exploratory analysis on image valance found that negative images (compared to neutral) benefited learning for individuals with higher levels of psychopathy. Discussion will center on the benefits of manipulating emotion directly within the task as a means to assess th e validity of the IGT.

- Abstract:
- The debate surrounding how emotion and c ognition are organized in the brain often lead s to Damasio’s Somatic Marker Hypothesis. This theory endorses a highly interactive process between emotion and cognition, but has been criticized for being too broad to capture the specific links between the t wo. It also implies that emotion operates from a neural architecture that is dissociable from cognition. Although empirical findings from the Iowa Gambling Task lend support for the theory, this can promote a false dichotomy between emotion and cognition. Issues will be raised regarding the view that the theory and the task are ill - formulated to account for the phases of decision making. Further theoretical work may be required to align the task with Damasio’s view of emotion as integrated with cognition.

- Abstract:
- The use of open linked data in libraries is quickly developing as means of connecting digital content from the web to local library collections. In the world of cataloguing, metadata, and authority control, using controlled vocabularies through open linked data presents the possibility of providing library patrons with access to a seemingly unlimited expanse of digital resources. Encouraged by this potential, the Carleton University Library is currently implementing open linked data models within its institutional repository in order to connect users to digital content within our repository, our ILS, and beyond. This poster presents the ideas and processes behind this innovative project, and hopes to inspire other libraries to implement open linked data concepts in order to enhance the discoverability of their own digital collections. Learning Outcomes: • Clear explanation of open linked data concepts using diagrams to illustrate key points • How libraries of all sizes can utilize linked data for authority control to expand access to digital collections • How libraries can use linked data to promote and expand access to OA publications

- Abstract:
- Energy modeling and optimization studies can facilitate the design of cost-effective, low-energy buildings. However, this process inevitably involves uncertainties such as predicting occupant behavior, future climate, and econometric parameters. As presently practiced, energy modelers typically do not quantify the implications of these unknowns into performance outcomes. This paper describes an energy modeling approach to quantify economic risk and better inform decision makers of the economic feasibility of a project. The proposed methodology suggests how economic uncertainty can be quantified within an optimization framework. This approach improves modeling outcomes by factoring in the effect of variability in assumptions and improves confidence in simulation results. The methodology is demonstrated using a net zero energy commercial office building case study located in London, ON, Canada.

- Abstract:
- Libraries are quickly becoming spaces for more than just books and journals. At Carleton University MacOdrum Library, we used Minecraft to introduce elementary and high school students to the power of gaming as a tool to foster education, research and collaboration. In May 2015, we encouraged students to take part in a project that engaged them with a local project called the LeBreton Flats Redevelopment Project. The redevelopment project led by the National Capital Commission (NCC), shortlisted four developers and published their proposals for the community to see. Using the criteria presented by the four pre-qualified proponents, the students were asked to research and propose their own ideas for the space. Using a scale version of the space in Minecraft, the students built their proposed plan for the space in a 1:1 scale replica of LeBreton Flats.

- Abstract:
- Closing the Loop: Community Engaged Pedagogy in Business Courses is a CACSL and Carleton Raven’s Den-funded CFICE evaluation project that looks at the impact on Sprott School of Business’s community partners of adopting a community service learning approach to pedagogy. Over a number of years and across a variety of courses, Sprott has implemented projects ranging in duration and topic in order to facilitate a ‘practice’ perspective for the students in Sprott’s Bachelor of Commerce and Bachelor of International Business programs. Sprott has received lots of feedback from students, in the form of anecdotal accounts and more structured feedback exercises, and some feedback from community partners, but mostly the latter was limited to student performance during the actual project and anticipated benefits should the organization adopt the recommendations made by the student teams. Sprott therefore undertook this study to determine the impact their CSL projects made on community partners over a longer term. This project is still ongoing, with evaluations scheduled for the Fall/Winter term from 2016 – 2017.

- Abstract:
- This paper is intended to inform discussions between industry and government policymakers in and beyond Ottawa, Canada about climate change and potential impacts on residential development regulations and corresponding industry practices. Ultimately, both private and public stakeholders must acknowledge the impacts of urban form on greenhouse gas (GHG) emissions, and, conversely, the impacts of climate change on cities, for any meaningful progress on urban sustainability to ensue. Section 1 introduces the basic relationships between urban development and climate change. Urban form is directly tied to energy consumption and GHG emissions, mainly through building and transportation energy consumption. Section 2 summarizes regional changes from climate change projected by various research organizations. Projected weather changes include more severe heat waves, rain and freezing rain in the future, with flooding identified repeatedly as the main concern for the Ottawa region. Section 3 reflects on the potential impacts of more severe weather on buildings and on the building industry. Impacts may include risks to structures and workers, as well as shifting regulations and insurance liabilities. Section 4 provides an overview of changes to government environmental policies that may signal future regulatory change. And finally, Sections 5 and 6 pose questions of interest for future regulators and builders.

- Abstract:
- The purpose of this article is to improve understanding of internationalization as a strategic response to the catalysts of globalization and the knowledge society. The paper will attempt to critically identify and interpret how the aforementioned elements are being recontextualized and translated into responsive internationalization policies and systemic institutional change. The article takes a critical analysis approach on current internationalization efforts and provides a conceptual framework for developing a performance indicator set through a combination of institutional change theory (North 1990) and the Delta cycle for internationalization (Rumbley 2010). Recommendations on future research areas are made at the conclusion of the article.

- Abstract:
- During the past few years, a relatively new technology has emerged in North America and changed the way professionals design and build wood structures: Cross-laminated Timber (CLT). CLT panels are manufactured in width ranging from 600 mm to 3 m. As such, fastening them together along their major strength axis is required in order to form a singular structural assembly resisting to in-plane and out-of-plane loading. Typical panel-to-panel joint details of CLT assemblies may consist of internal spline(s), single or double surface splines or half-lapped joints. These tightly fitted joint profiles should provide sufficient fire-resistance, but have yet to be properly evaluated for fire-resistance in CLT assemblies. The experimental portion of the study consisted at conducting ten (10) intermediate-scale fire-resistance tests of four (4) types of CLT panel-to-panel joint and three (3) CLT thicknesses. The data generated from the intermediate-scale fire tests were used to validate a finite element heat transfer model, a coupled thermal-structural model and a simplified analytical model. The simplified analytical model presented in this thesis is an easy-to-use design procedure for evaluating the fire integrity resistance of four commonly-used CLT panel-to-panel joint details and could potentially be implemented into building codes and design standards. Based on the test data and models developed in this study, joint coefficient values were derived for the four (4) types of CLT panel-to-panel joint details. Joint coefficients are required when assessing the fire integrity of joints using simple analytical models, such as Eurocode 5: Part 1-2. The contribution of this study is to increase the knowledge of CLT exposed to fire and to facilitate its use in Canada and US by complementing current fire-resistance design methodologies of CLT assemblies, namely with respect to the fire integrity criterion. Being used as floor and wall assemblies, designers should be capable to accurately verify both the load-bearing and separating functions of CLT assemblies in accordance with fire-related provisions of the building codes, which is now feasible based on the findings of this study.

- Abstract:
- A realistic speech synthesis tool could be used in dynamic therapeutic applications as well as revolutionize the animation pipeline in the entertainment industry. In this thesis, we propose a data-driven speech synthesis method that uses Viseme Transition Units (3D animation data describing the transition between mouth shapes) in the stead of the static visemes used in classic data-driven speech synthesis methods. To test this method, viseme transitions were recorded using optical flow and blob tracking algorithms, analyzed, and imported into Autodesk Maya to dynamically animate a custom mouth rig based on user input.

- Abstract:
- This dissertation traces the rise of the district as a system of administration across two historical periods: the deployment of districts by the Hudson’s Bay Company (1815-1840), and the spread of districts throughout England following the implementation of the New Poor Laws (1790-1860). By studying these episodes the project interrogates how what was initially a technique to rationalize the costs of administration became a system of documentation that supported the centralization of knowledge and the rule of population. I develop three theses on the effects of ruling through districts. First, I argue that administering through districts reworked 18th-century practices of Linnaean observation into 19th-century practices of inspection. Second, I argue that districts were used in both the HBC and in England to police the mobility of undesirable populations. Districts were used to document and control the mobility of unproductive labour and, thereby, solidified capitalist social relations. Last, I argue that as a system of spatial partition and documentation, the district formed the connective tissue that joined bureaucratic rule, the census of population, and biopower. I argue that ruling through districts supported the census of population through the creation of an administrative order where the surveillance of human beings was imagined to be continuous and equalized across time and space. The documentation of people, land, and things at the scale of the district made population visible as an object conditioned by the climate, means of subsistence, and topography of each district. As such, ruling through districts stabilized population as a biopolitical object of rule.

- Abstract:
- In a stadium installation of Wi-Fi, ideally a single access point could be used to illuminate a section with little interference from adjacent sections. This can be done with the use of a square beam. This thesis explores the creation of a square beam. The size of the array was reduced by removing low power elements. The sparse array allowed space for a sub-array to be placed in order to reactively cancel out sidelobes. A feed network was designed to provide the correct power and phases to the elements without the use of amplifiers or phase shifters. A number of power dividers were also a focus of this design. A return loss reduction method facilitates determining additional lengths of microstrip line without the need to simulate the full array. While the results of this prototype did not meet all specification, it does however, provide a framework to further explore.

- Abstract:
- Changes occurred to the writing of History in eighteenth-century Scotland. Dissatisfied with traditional historical priorities Scottish historians changed the focus of their writing to reflect what was more relevant to contemporary sensibilities, giving new importance to the social aspects of daily life, the inward life of the sentiments, and the history of manners. This refocusing of historical emphasis was a response to a vibrant commercial society, to the era's social interests, to the period's predilection for delicate sensibilities and refined feelings, and to a burgeoning middle class. One of these new genres of historical writing was called conjectural history. This study discusses conjectural history, it asks a methodological question, and it looks at several different examples of the historical genres being written at this time.

- Abstract:
- A phenomenological experimental study was presented for understanding the effect of cyclic loading, generally experienced by typical modern aircraft structures during flight, on the propagation of micro-mesoscopic damage in carbon fibre reinforced composite laminates. Testing was carried out by employing ultra-high resolution SkyScan 1173 XR-micro computed tomography to identify and assess damage progression during fatigue testing. It provided qualitative as well as quantitative assessments of the damage in the composites which supported the analytical investigations. An in-house solution was developed for statistically analyzing the occurrence, frequency and geometry of cracks throughout the fatigue life. This methodology was used to process the data from scan for the purposes of visualizing damage initiation and propagation. Hence, quantitative analysis could be performed. Analysis resulted in the definition of fatigue crack growth rates, da/dn for each of the 3 orthogonal planes, which was interpreted in terms of the 3 damage modes; opening, in-plane shear and out-of-plane shear. By applying linear elastic fracture mechanics (LEFM) laws, strain energy release rates were calculated, while differentiating between modes II and III in a novel manner. For verifying the parameters obtained, definite cracks were traced and analyzed. Finally, a methodology was implemented to import the damage model into a finite element analysis (FEA) tool to be used for crack growth analysis, and simulations were compared to experimental findings.

- Abstract:
- This thesis examines Soviet medicine in Central Asia from the mid-1920s until Stalin's death in 1953, using this subject to explore the tensions and contradictions of Soviet socialism in the region. Previous studies have demonstrated how Soviet rule in Central Asia could appear simultaneously as a form of empire, reifying differences between ruler and ruled, and as a universalizing project of modern statehood, aimed at transforming diverse peoples into a homogeneous citizenry. Yet scholars have rarely explored why and how these contradictory tendencies could coexist within the Soviet project. Through the lens of medical discourse, this thesis examines the nexus of colonizing and modernizing impulses within Soviet power, arguing that these tendencies proved interrelated and even mutually supporting within the Soviet imagination of Central Asia. Considering medicine as an important element of socialist construction, it explores the seemingly colonial structure of the universalizing, anticolonial project of Soviet modernity.

- Abstract:
- The TGF-β signaling pathway with its associated transcription factors (SMADs) was studied in the red-eared slider (Trachemys scripta elegans; liver, heart, white skeletal muscle, red skeletal muscle, and kidney) as a model for anoxia tolerance and the African clawed frog (Xenopus laevis; liver and muscle) as a model for dehydration resistance. In addition, protein expression levels of precursor cytokines were measured, as well as known genes and proteins downstream of the SMAD signaling pathway, such as c-Myc, and AP-1 proteins. The data showed that selective control of different SMAD isoforms occurred in response to environmental stress, the mechanism being reversible protein phosphorylation. Cellular responses and signaling profiles were observed to be highly tissue-specific and stress-specific. SMADs were shown to play a role in the hypometabolic response of both animal models through the regulation of cell cycle arrest, angiogenic processes, and oxidative injury management strategies.

- Abstract:
- The conceptual design approach is meant to address the challenges faced by an architect when it comes to creating a contemporary Orthodox Christian church. The design would have to adapt to various urban, architectural and social conditions that significantly differ from those of the previous eras. This design approach establishes a framework that allows the integration of the various design aspects of such a complex architectural object as the Orthodox Christian church at the conceptual design stage. This thesis focuses on the creation of the architectural narrative or the information layer integrated in the building design as a method of communicating a theological concept in terms applicable to the current cultural and temporal context.

- Abstract:
- When David Hume could not experience the impression of a necessary connection in the constant conjunction of two events, he reasoned that the necessity inherent in such a relation was the result of a feeling or desire; a determination of the mind to connect one event to another. Immanuel Kant, on the other hand, argued that the idea of cause was an innate structure of thought that provided the objective validity to a causal relationship. I argue that Kant’s combination of sensible intuition and the faculty of thought provides a more comprehensive and objective explanation of how we understand the necessary connection between a cause and its effect.

- Abstract:
- The design methodology and phase noise analysis of a multiphase bipolar Ku-band Rotary Travelling-Wave Oscillator (RTWO) is presented. Lack of symmetry in an RTWO can result in oscillation in an unwanted mode rather than travelling-wave mode. In order to determine the oscillation mode and also measure the phase shift, we have proposed a frequency domain phase shift measurement technique, intended for an 18 GHz RTWO, which is presented. Using a 0.25 μm BiCMOS process from NXP Semiconductors, the fabricated RTW-VCO gives access to eight different phases in steps of 45 degrees and achieves a tuning range of 1.2 GHz centred at 17.5 GHz. A beam-forming technique that utilizes the RTWO for LO phase shifting is also presented. In order to configure a two-element-array transmitter to show the functionality of an RTWO for beam-forming, we have designed and characterized a high frequency distribution network, a switching bank, a power amplifier (PA) and also a patch antenna. All of these components, except the antennas, have been integrated on a single, 19 mm2, silicon die along with the RTWO. The measurement of the full system is performed with the aid of two off-chip antennas fabricated on a high frequency printed circuit board. The combined system is fully functional and the measurement results are provided. This research demonstrates the relevance of the RTWO for integration in phased-array transmitter systems.

- Abstract:
- This study examines the feasibility of a motion and haptic integrated system for the purpose of controlling a humanoid robotic arm. An Oculus head-mounted display was integrated to determine if there was an observable difference between third-person and first-person perspective control. We examine different methods of robotic control in humanoid robots and the precedence of head-mounted displays and motion control in current literature, as well as look at vibration as haptic feedback to relay the limitations of the robot. An experiment was completed with the prototype system in which 30 participants were able to complete the given tasks without fail. A learning period was observed when comparing completion times of the first task attempted to subsequent tasks. The majority of participants found the method of control to be intuitive, the inclusion of first-person perspective to be beneficial, and the vibration feedback to be either inconsequential or confusing rather than helpful.

- Abstract:
- Modern health management approaches for gas turbine engines (GTE) aim to acquire precise information about the health state of the GTE components to optimize the maintenance decisions with respect to both the economy and safety. The task becomes more challenging for the GTE parts inaccessible to direct measurements with the available sensors of the GTE control system. This article-based thesis integrates a set of five coherent research work to address this problem. A detailed nonlinear thermodynamic model for single shaft GTEs is developed to predict the expected cycle parameters for the GTE in the healthy condition. In reality, the measured cycle parameters gradually deviate from the prediction due to performance deterioration. Physics-based performance indicators are defined based on the deviations in the measured performance parameters, compared to the respective model predictions. The indicators can effectively monitor the GTE performance deterioration in both short-term and long-term regimes. In the next step, effect of the air humidity is taken into account to enhance the GTE model, and it is shown that the enhanced model can improve the performance monitoring by reducing the uncertainties. In order to separate the effects of different fault modes, an inference-based model is developed to predict the short-term recoverable performance deterioration due to the compressor fouling under different ambient and operating conditions. For the long-term non-recoverable performance deterioration due to the degradation mechanisms in the turbine hot section, two steps are undertaken; 1) a state estimation framework is developed for nonlinear/non-Gaussian systems with non-uniform time steps to track a degradation symptom of the turbine, i.e., loss of isentropic efficiency, using the observable performance indicators, and 2) the state estimation framework is extended to multidimensional dynamical systems with stochastic inputs for simultaneous tracking of two degradation symptoms, i.e., loss of isentropic efficiency and increase of the mass flow, using the observable parameters, provided by the GTE operating system. The developed techniques and frameworks are verified and validated, using a set of three-year operating data from an industrial GTE in a power plant.

- Abstract:
- In this thesis, first, we study the weighted region problem (WRP), which is to compute a geometric shortest path on a weighted partitioning of a plane. Recent results show that WRP is not solvable in any algebraic computation model over rational numbers. Thus, scientists have focused on approximate solutions. We first study the WRP when the input partitioning of space is an arrangement of lines. We provide a technique that makes it possible to apply the existing approximation algorithms for triangulations to arrangements of lines. Then, we formulate two qualitative criteria for weighted short paths. We show how to produce a path that is quantitatively close-to-optimal and qualitatively satisfactory. The results of our experiments carried out on triangular irregular networks show that the proposed algorithm could save, on average, 51% in query time and 69% in memory usage, in comparison with the existing method. We also study some variants of the Frechet distance. The Frechet distance is a commonly used measure to capture the similarity of polygonal curves. Firstly, we study a robust variant of the Frechet distance since the standard Frechet distance exhibits a high sensitivity to the presence of outliers. Secondly, we propose a new measure to capture similarity between polygonal curves, called the Minimum Backward Frechet Distance (MBFD). More specifically, for a given threshold epsilon, we are searching for a pair of walks for two entities on the two input polygonal curves such that the union of the portions of required backward movements is minimized and the distance between the two entities, at any time during the walk, is less than or equal to epsilon. Thirdly, we generalize MBFD to capture scenarios when the cost of backtracking on the input polygonal curves is not homogeneous. Lastly, for a given graph H, a polygonal curve T, and a threshold epsilon, we propose a geometric algorithm that computes a path, P, in H, and a parameterization of T, that minimize the sum of the length of walks on T and P whereby the distance between the entities moving along P and T is at most epsilon.

- Abstract:
- Wild fish population are often impounded by hydropower dams, which can restrict migration and habitat requirements, while making fishes susceptible to deleterious harm from entrainment through spillways and turbines, stranding from dewatering, as well as hydrokinetic developments that are being proposed for installment within tailraces. With applying acoustic biotelemetry and using model selection, I investigated the spatial ecology and biological responses from Lake Sturgeon and Walleye relative to hydropower developments on a large river. The results in chapter 2 document the spatial ecology of wild fishes within a run-of-river impoundment. In chapter 3, biotelemetry was used to investigate the risk of impacts from hydrokinetic turbines on wild fishes. This information will help to enhance management for Lake Sturgeon and Walleye populations that are impounded due to hydropower developments, and help guide best practices for commercial operations for hydrokinetic turbines that are placed within tailraces of hydropower stations.

- Abstract:
- Spatial-numerical associations (SNA) have been studied in various numerical and non-numerical tasks. Classically, participants respond faster with their right hand to larger numbers and faster with their left hand to smaller numbers even when number identity is irrelevant. SNAs are often explained as activation of a left-to-right mental number line. SNAs may reflect magnitude processes, relative order, or both. In the present research, I explored the SNA in an order judgment task. In three experiments, participants judged whether three digit sequences were ordered or unordered. People with more efficient calculation skill are faster and more accurate on order judgments than those with less efficient skills. Thus this task is assumed to capture important aspects of the mental representation of numerical sequences. I hypothesized that participants would show a SNA similar to that in other number tasks (e.g., parity, number comparison), that is, faster right hand responses to number sequences that are assumed to activate the right side (e.g., 6 7 8) and faster left hand responses to number sequences that are assumed to activate the left side (e.g., 2 3 4) of the mental number line. In three experiments, ordered but not unordered sequences showed consistent evidence for a typical SNA. In Experiment 1, Asian-educated individuals showed a stable SNA effect on both ascending and descending sequences whereas Arabic-speaking participants showed no significant SNA effects. English-speaking participants showed a typical SNA on descending sequences and a reversed SNA on ascending sequences. In Experiments 2 and 3, individuals with better arithmetic fluency showed a typical SNA. In Experiments 2 and 3, analyses using a multi-factor ANOVA design did not show evidence for SNARC effects. Instead, SNARC effects were found only using slope analyses on differences in responses with the right versus the left hand. The results are discussed in relation to the processes involved in sequence judgments and how those might differ from the processes involved in other numerical tasks. In summary, the SNA was elusive, even though participants were quite sensitive to number magnitude and the task itself required order judgments, which presumably should have activated the mental number line.

- Abstract:
- Acoustic signalling is common in bark beetles (Curculionidae: Scolytinae) but has been underappreciated in the literature, resulting in many unanswered questions regarding their acoustic ecology. The goal of this work was to answer some outstanding questions in the economically important Dendroctonus genus using mainly Dendroctonus valens. Dendroctonus spp. produce complex and variable acoustic signals in many contexts. Addressing the question of why they signal, I found that during courtship the ultimate function of signals was linked to female mate choice. Not only did chirp characteristics correlate with signaller fitness, but females differentiated between and made decisions about potential mates based on chirp variability in courtship song performances. The question of how chirp variability is produced was then addressed. I found the proximate mechanism of chirp production is a form of ‘spring stridulation’, where elastic potential energy is stored as fuel for stridulation. Altering the number of times the energy store was reloaded during a chirp led to the variable pulse pattern of the distinct chirp varieties. Finally, I addressed the question of sexual dimorphism in sound production. I noted that females produced sound in the contexts of disturbance and territoriality and further that they do so by way of an alternative mechanism to that of sound production in males. However, female sounds were erratic and rare, and their presence did not evoke a conclusive behavioural response in conspecifics, leading to an overall lack of support for a communicative function of female sound. My thesis research forms the most comprehensive story of the ultimate and proximate nature of sound production in both sexes of a destructive group of tree-killing bark beetles.

- Abstract:
- Correctional institutions are looking to adopt a non-obtrusive method for monitoring the vital signs of inmates in Canada. Doppler radar has been previously investigated as a potential method of vital signs detection and monitoring. This thesis presents an algorithm which uses the baseband output signal received by a Doppler radar to estimate the breathing rate from the detected motion associated with breathing. A reliability measure is provided with breathing rate estimates through the analysis of various signal quality indices. Results demonstrate that the algorithm is able to estimate the subject’s breathing rate (with high reliability) when the subject is motionless and breathing normally (mean error of 6 breaths per minute). The algorithm cannot accurately estimate the breathing rate when the subject is moving or holding their breath (mean error of 21 breaths per minute). During breath holds, it was found that the algorithm can likely estimate the subject’s heart rate.
