Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1999
Subjects: subject: Engineering, Electronics and Electrical.

description: Today's road workers increasingly demand computing and communications capability that is available from any place, in any form, and at any time. Such network access primarily needs to be independent of location and device, which identifies 'global mobility support' across wired and wireless networks, popularly referred to as PCS in North America and as UMTS in Europe. In the computing world, the emergence of the ubiquitous information access is noted as Nomadic Computing. The two types of mobility: terminal and personal, essentially characterize it. The thesis presents application layer solution, referred to as Nomad's Personal Access System (NPAS ) that emulates 'personal mobility' in a virtual network, with the aim of supporting 'communication' needs of the mobile users. The thesis proposes a data model that is required to provide personal mobility. The data model allows specifying the communication and computing environment, i.e., resource (services) profile of the user both at home and visited sites. As part of data management scheme, software agents is leveraged to create dynamic data pertaining to a current resource (services) profile of a nomad at a visited location. The data management involves the use of IETF's Lightweight Directory Access Protocol (LDAP) and inter-site negotiation agent called Site Profile Agent. The inter-site negotiation protocol is built using Knowledge Query and Manipulation Language (KQML). NPAS aims to deliver messaging services as the final promise; however, messaging services are only discussed to elaborate the use of the proposed data model.

description: An essential prerequisite for radars in automotive applications, safety systems, future autonomous driving, and industry applications is the reliable operation even under difficult conditions such as interference from other radars. Recently, digital radar principles such as orthogonal frequency-division multiplexing (OFDM) gained increasing attention. In this letter, an interference-robust processing for OFDM radar signals using compressed sensing (CS) is presented, which is particularly suitable for random OFDM but also applicable to stepped and standard OFDM. It allows robust radar operation in presence of interfering signals that have a comparable low instantaneous bandwidth and high narrowband power. The method is validated experimentally using measurements of an OFDM radar setup at 76 GHz and a state-of-the-art FMCW radar as an interferer.

description: Background: Computational biology requires the reading and comprehension of biological data files. Plain-text formats such as SAM, VCF, GTF, PDB and FASTA, often contain critical information which is obfuscated by the data structure complexity. Results: bioSyntax ( https://biosyntax.org/ ) is a freely available suite of biological syntax highlighting packages for vim, gedit, Sublime, VSCode, and less. bioSyntax improves the legibility of low-level biological data in the bioinformatics workspace. Conclusion: bioSyntax supports computational scientists in parsing and comprehending their data efficiently and thus can accelerate research output.
Jesus' parousia in the context of the crucifixion: An exegetical analysis of Matthew 24:1-26:2 using the semiotic method.

Subjects: subject: Religion, Biblical Studies.

description: The present research deals with Matthew's version of the eschatological discourse. Our first step was to determine the boundaries of this text. Our survey of scholarly opinions has shown that a general consensus regards 24:1 as the beginning of the discourse, while it places the ending in 25:46. We are in agreement with the view about the beginning in 24:1 but contest the ending. Our proposal is that 26:2 marks the ending of this particular discourse rather than 25:46. Subsequently, 26:1-2 is an essential part of this eschatological discourse. From the content of the text there are several reasons in support of this position. From a theological point of view we consider the disciples' question in 24:3 to be an expression of their eschatological anxiety and expectation that after his departure Jesus as the Messiah will return to reclaim possession of the temple. But Jesus' announcement in 26:2 that the Son of Man will be crucified begs the question: how can Jesus' $\pi\alpha\rho o\upsilon\sigma\acute\iota\alpha$ take place if he will be crucified within two days? This research is an effort to provide adequate answers to the structural and theological questions which arise in the course of reading this text. As our modus operandi we have used the semiotic method in its two stages of the discursive and narrative sequences, and then we made a theological commentary. Two hypotheses based on the above question have guided our investigation: one, the Son of Man's crucifixion on the day of Passover implies that it is necessary for the Son to go to his Father in order to come back empowered to judge all the nations, and two, the $\pi\alpha\rho o\upsilon\sigma\acute\iota\alpha$ of the Son of Man is above all a spiritual and personal experience of faith for those who await his coming. The whole thesis consists of four chapters. The first chapter is devoted to the cutting of the text. The second and third deal with the discursive and narrative sequences of the text respectively. While the first half of the fourth chapter tackles the coherence of the discursive and narrative elements, the second half of the same chapter is a theological commentary.

Universal Topological Quantum Computation in a Superfluid Universe
Creators: name: Genetay Johansen, Emil Linus Sebastian
Publisher: name: Swinburne
Year: 2024

description: Quantum computers promise to unlock immense computational power far beyond conventional computers. Yet, their potential is hindered by instabilities, causing computational failure. Topological quantum computers, though inherently stable, require exotic phases of matter that are hard to realise. This work reveals that a special kind of systems known as superfluids may serve as a platform for such computers, demonstrating that vortices within them emulate the interactions of elementary particles like electrons and quarks, and even gravity. Interactions in such a “superfluid universe” are shown to facilitate fault-tolerant quantum computation, presenting a novel approach to harnessing the power of quantum systems.

description: Direct photoelectrochemical (PEC) solar water splitting has the potential to be a key element in a sustainable energy supply chain. However, integrated PEC systems based on metal oxides still lack the high efficiencies required for large-scale, economically feasible applications. A main obstacle for the realization of higher solar-to-hydrogen efficiencies is the appropriate design of the semiconductor–catalyst and semiconductor–electrolyte interfaces. Thus, a more accurate understanding of the energy loss mechanisms and the driving forces that determine the charge separation, transport and recombination of electrons and holes in a PEC device would be instrumental for the selection of the most appropriate design routes. In this context we highlight a common misconception within the PEC research community, which is to consider the built-in electrical field at the solid/liquid interface as essential for charge separation. We subsequently emphasize the established viewpoint within the photovoltaic research community that the gradient of the electrochemical potential is the principle driving force for charge separation and efficient solar energy conversion. Based on this realization, we argue that improved contact design in PEC devices should be one of the main research directions in the design of PEC devices. To address this challenge, we take a closer look at how optimized contacts have been constructed so far and present potential design approaches which can be used to further improve the performance of PEC devices.
Infrared spectroscopic investigation of boron halides adsorbed on silica.

Publisher: name: Université d'Ottawa / University of Ottawa

Subjects: subject: Biology, General.

description: An infrared spectroscopic study of the adsorption of BF3 and BCl3 on silica has been carried out. The silica samples were dehydrated under vacuum at various temperatures from 400-1020°C before admitting the adsorbate to the reaction cell and the nature of surface species produced depended on this pretreatment temperature. Upon adsorbing BF3 on a silica sample that had been previously evacuated at temperatures below 1000°C, a set of bands were produced which were replaced by a new set of bands on evacuation. Similar results were observed with BCl3 treated silica. However, during this evacuation, a growth of the 3749 cm-1 Si-O-H band was observed after BF 3 adsorption but a corresponding growth of the 3700 cm-1 B-OH band was observed after BCl3 adsorption. Further, the initial set of bands, produced on adding BF3 to silica samples which had been previously dehydrated at temperatures above 1000°C were extremely stable to evacuation, whereas the corresponding bands with BCl 3 were again replaced on evacuation. A mechanism is proposed that would explain the observed results. Some of the features of this mechanism are: (1) BX3 (X=F, Cl) initially reacts with the surface hydroxyls to give Si-O-BX2 type species. (2) On evacuation, these groups further react to give the Si-O2 -BX type species. (3) A small amount of 'H2O' is available to the surface during evacuation and this 'H2O' reacts with the BX3 treated surface to refurnish Si-O-H groups. (4) However, the Si-O-BCl2 and the Si-O2-BCl groups further react with this 'H2O' to give Si-O-B-(OH)2 and Si-O2 -B(OH). It has been shown that both BF3 and BCl3 are chemically adsorbed on silica evacuated at very high temperatures. It has been proposed that on these surfaces, various other active sites, for example Si-O• radicals and Si-O-Si bridges are possibly present. An attempt has been made to study the bands due to BO2 symmetrical stretching modes in the 1200 cm-1 region by adsorbing BX3 on various other oxides, e.g. Al2O3, TiO2, MgO and ZnO. It has been shown that the surface silanols exchange with H2O 18 at elevated temperatures and a maximum 70% exchange has been obtained at 400°C. A new band present at 3738 cm-1 is assigned to the OH stretching mode of Si-O18-H. Using the O18 exchange technique it has been possible to assign surface adsorbate stretching modes arising from species of the type Si-O-BX2 .

Publisher: name: Swinburne
Year: 2024

description: Additively manufactured lattice structures possess high strength to weight ratios and energy absorption capacities while offering a higher design freedom. This thesis focuses on evaluation of mechanical performance of functionally graded (FG) polymer and metal lattice structures aiming to enhance the energy absorption capacities. The structures were additively manufactured in the form of cubes and beams and tested under uni-axial compression and three-point bending, respectively. The experimental results were employed to develop and validate finite element (FE) models which were subsequently utilised for analysing the behaviour of FG lattices subjected to changes in gradient, loading direction, and loading velocities.

description: Ein Mikrocontroller verbraucht beim Ausführen von unterschiedlichen Maschineninstruktionen unterschiedlich viel Strom, weil verschiedene Teilnetze des Chips aktiv sind. Die Aktivitätsdauer dieser Teilnetzte variiert ebenfalls pro Instruktion. Dabei entsteht für unterschiedliche Instruktionen ein charakteristisches Muster auf der Stromverbrauchskurve, die in dieser Arbeit als Templates bezeichnet werden. Solche Templates wurden für ausgewählte Instruktionen exemplarisch aufgenommen, um ein Programm anhand seines Stromverbrauches rekonstruieren zu können. Die Templates wurden hierfür in drei Klassen unterteilt und qualitativ untersucht. Zwischen den Templates der unterschiedlichen Instruktionsklassen wurde eine gut ausgeprägte Trennschärfe im Vergleich zu den Templates innerhalb einer Klasse festgestellt. Durch Korrelation von Sprunginstruktionen konnte der gemessene Stromverlauf in Ausführungsblöcke unterteilt und in einem Programmflussgraphen modelliert werden. Damit möglichst große Teile eines Programms analysiert werden können, wurde ein Fuzzer entwickelt, der versucht eine größtmögliche Zahl an Programmpfaden auszulösen und somit die Codeabdeckung der Analyse zu steigern. Mit dem Programmflussgraphen als Feedbackinformation war es möglich, dass der Fuzzer in den getesteten Fällen eine bessere Codeabdeckung als ein rein zufallsbasierter Fuzzer erzielen konnte.

description: In this article, I explain how to run distributed machine learning workloads on a Kubernetes cluster using PyTorch’s Distributed Data Parallel (DDP) approach. DDP enables efficient multi-node training by replicating the model across processes on different nodes, each processing a unique subset of the training data. After computing gradients locally, DDP synchronizes them across all processes to maintain model consistency. It supports multiple communication backends like NCCL, Gloo, and MPI, allowing flexibility based on the cluster’s networking and hardware configuration.

description: Cigarette butts are an important human firebrand and account for a significant amount of man-made fires. To better address forest fires caused by cigarette butts, the influencing factors governing the ignition probability of cigarette butts can be used to establish a prediction model. This study obtains the influencing factors of the ignition probability of cigarette butts in order to establish a prediction model by constructing fuel beds composed of Mongolian oak leaves with varied fuel moisture content and packing ratios. A total of 2520 ignition experiments were then conducted by dropping cigarette butts on the fuel beds to test the burning probability of the fuels under varied wind speeds. Moisture content, wind speed, and their interaction significantly influenced ignition probability. In the absence of wind, the ignition probability is zero. The maximum moisture content of Mongolian oak leaves that could be ignited by cigarette butts was 15%. A logistic model and self-built model for predicting the ignition probability were established using these results; the mean absolute error values for the two models were 2.71% and 1.13%, respectively, and the prediction error of the self-built model was lower than that of the logistic model. This is important research to mitigate the threat of forest fires due to cigarette butts given the frequent occurrence of these events.

description: After weight loss, most individuals regain lost weight. Interventions to support the transition from successful loss to weight loss maintenance (WLM), regardless of the method of prior weight loss, are needed. The aims of this study were to (1) develop a face-to-face behavioural intervention session to support overweight and obese individuals who have recently lost a clinically significant amount of weight in the transition to WLM; (2) to assess the single-session intervention for acceptability and feasibility prior to its use in a larger, 12-month, multi-component trial; and (3) to optimise the intervention session for future use based on participant feedback. Participants with a Body Mass Index of ≥25 kg/m2 prior to a ≥5% weight loss in the previous 12 months were recruited via the local government authority and community-based advertisements. Each attended the one-hour session with a trained facilitator, which focused on setting maintenance-relevant weight, eating, and physical activity goals. Semi-structured interviews were carried out immediately post-session to obtain feedback on the acceptability of this intervention component. Data were used to generate recommendations for changes to the session, which were discussed by the team, and used to optimise the session. Seventeen participants (13 female; median WL = 13%) were recruited. All participants evaluated the intervention session positively; 11 participants suggested improvements including reducing information provision in favour of greater focus on identifying and coping with barriers, and the inclusion of practical examples. The systematic refinement and optimisation process resulted in an acceptable and feasible face-to-face behavioural intervention session (described here), which will be tested as part of a multi-component intervention. We anticipate the session could be used to supplement existing support including online services, and has the potential to benefit people who have lost a clinically significant amount of weight to achieve WLM over the long term.

A novel enantioselective synthesis of allenic esters and amides
Creators: name: Apsimon, Megan K
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2009
Subjects: subject: Chemistry, Organic.

description: In recent years, allenes have become recognized as useful synthons in organic chemistry. Their unique orthogonal pi-bond system can be used in a variety of regio- and stereoselective carbon-carbon bond-forming reactions. Chiral allenes also have the ability to transfer their chirality to one or more new chiral centres. Despite this usefulness, the synthesis of chiral allenes is quite limited. Most methods to synthesize asymmetric allenes require chirality transfer from a pre-formed chiral centre, while only a handful of methods exists which form an asymmetric allene from achiral starting materials. We have discovered a new method for synthesizing chiral allenes using achiral 3-alkynoates or 3-alkynamides. Treatment of a propargyl carbonyl compound with a catalytic silver source and a chiral Lewis Acid in the presence of a weak amine base results in the formation of chiral allenic esters and amides. Initial reactions with 3- alkynoates lead to the discovery of AgSbF6 and (R)-(S)-JOSIPHOS as the ideal catalyst system, and N-methylmorpholine as the base. When the reaction was performed in a mixture of methanol/THF, this resulted in the formation of allenes with ee values higher than 90%. The reactions did not complete, however, resulting in a mixture of alkynes and allenes which was not separable by chromatography. This problem was solved by applying the same methodology to 3-alkynamides. Within an hour at 0°C, the reaction was finished, and the alkynes and allenes could easily be separated chromatographically. Nine different allenic amides were synthesized, in 27-95% yield, and 90-99% ee. Once the allenes were synthesized, we determined the absolute stereochemistry, discovering that our methodology formed the (S)-allenes. We did this by transforming the allenes to a known butenolide via and iodolactionization reaction and removal of the iodine. By comparing the experimental optical rotation to the known optical rotation, we were able to determine the absolute stereochemistry. This was also confirmed by applying the Lowe-Brewster rule, a rule which applies only to allenes. In allenes, the absolute stereochemistry and axial helicity of the compound can be used to predict the direction of the optical rotation, and vice versa.

description: We investigate bright and dark diffractive focusing emerging in the free propagation of specific wave profiles. These general wave phenomena manifest themselves in matter, water, and classical waves. In this article, we lay the foundations for these effects and illustrate their origin in Wigner phase space. Our theoretical studies are supported by experimental demonstrations of dark focusing in water waves. Moreover, by using different phase slits we analyze several aspects of bright and dark focusing for classical and matter waves.

description: There are a number of bacteria associated with livestock, one of which is Escherichia coli 157:H7, a pathogenic bacterium often found associated with animal feces, which has the potential to contaminate groundwater in many rural areas. Adhesion onto soil particles is also an important biogeochemical process controlling bacterial transport that is influenced by a number of interrelated variables including pH, ionic strength, solution chemistry, soil mineralogy, bacterial growth phase and metabolic activity. The main objectives of this thesis were to first assess the surface reactivity of E. coli K-12 (a model non-pathogenic bacterium) as a function of bacterial growth phase and activity and second, to determine the extent of E. coli adhesion to quartz and Fe-oxide, two common soil minerals, as a function of pH, using batch experiments. The titration results showed that lepidocrocite had the highest buffering capacity, then bacteria, and quartz the lowest. (Abstract shortened by UMI.)

description: Tumor infiltrating myeloid cells play contradictory roles in the tumor development. Dendritic cells and classical activated macrophages support anti- tumor immune activity via antigen presentation and induction of pro- inflammatory immune responses. Myeloid suppressor cells (MSCs), for instance myeloid derived suppressor cells (MDSCs) or tumor associated macrophages play a critical role in tumor growth. Here, treatment with sodium oleate, an unsaturated fatty acid, induced a regulatory phenotype in the myeloid suppressor cell line MSC-2 and resulted in an increased suppression of activated T cells, paralleled by increased intracellular lipid droplets formation. Furthermore, sodium oleate potentiated nitric oxide (NO) production in MSC-2, thereby increasing their suppressive capacity. In primary polarized bone marrow cells, sodium oleate (C18:1) and linoleate (C18:2), but not stearate (C18:0) were identified as potent FFA to induce a regulatory phenotype. This effect was abrogated in MSC-2 as well as primary cells by specific inhibition of droplets formation while the inhibition of de novo FFA synthesis proved ineffective, suggesting a critical role for exogenous FFA in the functional induction of MSCs. Taken together our data introduce a new unsaturated fatty acid-dependent pathway shaping the functional phenotype of MSCs, facilitating the tumor escape from the immune system.

description: In North America, the activated sludge process is commonly used in wastewater treatment. However, there are many aspects of the process that elude researchers, in particular, those that will ensure a successful control and optimization of the process. Because of the biological nature of the activated sludge process, its characteristics are highly dependent on environmental factors and hence can be very difficult to control and manage successfully. A very important factor contributing to an optimized activated sludge plant is the experience of its operators with the activated sludge process. This is achieved through the use of a variety of tools including traditional classroom training, computer based training, expert systems and simulation tools. Some of the tools aim to help the new operators acquire this experience quicker while others aim to enhance the experience of seasoned operators. This project presents a premise that an integration of these tools will be an effective and innovative way to help the operators achieve their goals. Hence, a design of an Integrated Training and Decision Support System (IT-DSS) has been proposed, and parts of the prototype system have been built. Preliminary results showed that such an integrated solution is feasible and realisable although a fully functional system has yet to be realised due to the scope limit. The results of this project provided solid and valuable starting points for the completion of such a step, and they also further support the value of the integration approach that has been put forth.

description: Rapid urbanisation generates risks and opportunities for sustainable development. Urban policy and decision makers are challenged by the complexity of cities as social–ecological–technical systems. Consequently there is an increasing need for collaborative knowledge development that supports a whole-of-system view, and transformational change at multiple scales. Such holistic urban approaches are rare in practice. A co-design process involving researchers, practitioners and other stakeholders, has progressed such an approach in the Australian context, aiming to also contribute to international knowledge development and sharing. This process has generated three outputs: (1) a shared framework to support more systematic knowledge development and use, (2) identification of barriers that create a gap between stated urban goals and actual practice, and (3) identification of strategic focal areas to address this gap. Developing integrated strategies at broader urban scales is seen as the most pressing need. The knowledge framework adopts a systems perspective that incorporates the many urban trade-offs and synergies revealed by a systems view. Broader implications are drawn for policy and decision makers, for researchers and for a shared forward agenda.

description: Abstract Quantum networks require interfacing stationary and flying qubits. These flying qubits are usually nonclassical states of light. Here we consider two of the leading source technologies for nonclassical light, spontaneous parametric down-conversion and single semiconductor quantum dots. Down-conversion delivers high-grade entangled photon pairs, whereas quantum dots excel at producing single photons. We report on an experiment that joins these two technologies and investigates the conditions under which optimal interference between these dissimilar light sources may be achieved.

A mathematical, statistical, probabilistic and strategic analysis of tennis
Creators: name: Pollard, Geoff
Publisher: name: Swinburne
Year: 2024

description: Tennis has a challenging tri-nested scoring system of points, games and sets. The candidate used mathematical and probabilistic techniques to determine the optimal serving strategy. He challenged the traditional measure of importance of each point with a new way of looking at importance. He developed tests for analysing the independence between points and then analysed point-by-point data. He introduced the analysis of tennis as a game of point-pairs, one to each service court, and he measured the efficiency of the different scoring systems and tournament structures. Finally, he outlined strategic decision making at major events such as the Australian Open.
Apprentissage incrémental de contraintes procédurales par une méthode mixte.

Publisher: name: Université d'Ottawa / University of Ottawa

Subjects: subject: Computer Science.

description: La méthode mixte d'apprentissage présentée ici et appelée ACP, permet l'acquisition de connaissances à partir d'exemples d'un concept. Ces exemples sont représentés par une séquence d'actions et de descripteurs. L'apprentissage consiste à générer les relations qui existent entre les actions et entre les descripteurs. Ces relations sont appelées contraintes procédurales. Les contraintes, qui existent implicitement dans les exemples, sont rendues explicites par la méthode. Notre approche constitue une extension essentielle à la méthode basée sur l'explication (Explanation-Based Learning: EBL). Elle permet d'apprendre à partir de plusieurs exemples positifs et négatifs et intègre l'apprentissage inductif avec EBL. C'est pourquoi on l'appelle méthode mixte. De plus, c'est une méthode incrémentale qui ne conserve pas en mémoire tous les exemples appris. En fait, la méthode EBL est utilisée pour apprendre le plus possible à partir d'un seul exemple. Tant qu'à la méthode SBL, elle est utilisée pour améliorer les connaissances provenant des exemples précédemment appris pour accepter le nouvel exemple. La méthode ACP est basée sur les résultats obtenus par la méthode EBL. Les connaissances apprises sont représentées par une définition du concept. Cette définition doit couvrir les exemples positifs et rejeter les exemples négatifs. Des exemples du prototype pour prendre le métro sont illustrés tout au long de la discussion.
Development of a novel carbohydrate-based method for the detection of norovirus from ready-to-eat foods

description: Norovirus is an enteric pathogen transmitted via the fecal-oral route. It is a leading cause of outbreaks and sporadic cases of gastroenteritis worldwide. Outbreaks of norovirus are often linked to contaminated food or water. Ready-to-eat foods are particularly prone to contamination, since they often require handling during preparation and are not usually heated before serving. Norovirus capsids have been shown to interact specifically with histo-blood group antigens (HBGAs). HBGAs are carbohydrates present on the surface of red blood cells, on mucosal epithelial cells and in bodily fluids. The work in this thesis used the interaction between norovirus and HBGAs to develop a method to detect norovirus in food samples. Magnetic beads were coated with multiple types of HBGA [A, B, H(type 2) and H(type 3)]. These beads were added to a 250 mL volume sample and concentrated using either the Pathatrix(TM) or iCropTheBug. Both systems were able to concentrate the beads from a 250 mL sample to 140 muL, using the magnetic properties of the beads. The RNA was then extracted from the sample and the presence of norovirus was determined using realtime Reverse Transcription-PCR. This method was successful at detecting norovirus from artificially-spiked and naturally-contaminated food samples. It was also able to detect multiple strains from norovirus genogroup I and II within the infectious dose range (10-100 particles). These results demonstrate that carbohydrate-conjugated beads can be successfully used to detect norovirus contamination of food products. This method can provide rapid and effective food testing for use in the investigation of suspected norovirus outbreaks.
