Publisher: name: Swinburne
Year: 2024

description: In Canada and elsewhere around the world Indigenous Peoples are struggling to rebuild their 'nations' and improve the socioeconomic circumstances of their people. We are embarking on a program of research in an effort to understand this phenomenon and to inform the process. In this paper we (i) explore the approach to development being adopted by Indigenous people in Canada; (ii) conduct a preliminary literature review; (iii) identify input indicators of entrepreneurship and business development capacity, process measures of development activity and an output indicator of development effectiveness and (v) identify the information available from secondary sources relating to these indicators and the gaps in information that will have to be filled by primary research.

The common life: An element of apostolic institutions of women.
Creators: name: Gallagher, Marjory D.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1995
Subjects: subject: Religion, History of.

description: In this work, the author explores the origins, development, understanding and praxis of the common life in apostolic religious institutes of women, and the evolution of related legislation. The dissertation attempts to bring together an understanding of the evolution of the common life, its place and meaning for apostolic religious institutes of women, the legislation regarding the common life, and the cultural and societal influences on the legislation and the life of the institutes. The first chapter presents an historical overview of the legislation regarding the common life, from the early days of the Church until and including the 1917 Code of Canon Law. The teachings of the Second Vatican Council constitute the heart of chapter two which analyzes the current legislation relevant to the common life, as well as its formulation, especially as it pertains to apostolic institutes of women. Particular attention is paid to Perfectae caritatis, section 15 (common life) and no. 8 (nature of apostolic institutes), and to selected canons addressing both these issues. Chapter three analyzes and interprets the response of North American apostolic women religious to the conciliar invitation to return to the sources. It traces the most salient efforts at both adaptation and renewal in the areas of the apostolate and the common life. It also points out certain trends which have affected both the understanding and the praxis of the common life. The fourth and last chapter analyzes and interprets implications for the future, in relation to balancing the requirement of the common life, the apostolic thrust of the institute, and the situations regarding membership which are affecting many institutes at present, and no doubt will continue to do so in the future. It recognizes the impact of societal and cultural attitudes, past and present, on both religious life and on ecclesiastical legislation. This chapter focuses on an interpretation of the common life more appropriate to the times and to the nature of apostolic institutes. Finally, some tentative revisions of certain canons are suggested.

description: Background: Little is known about whether patients’ socioeconomic status influences their access to elective general surgery in Canada. The purpose of this study was to assess the association between socioeconomic status and wait times for elective general surgery. Methods: Analysis of prospectively recruited participants’ data. The setting was six hospitals in the Vancouver Coastal Health Authority, a geographically defined region that includes Vancouver, British Columbia, Canada. Participants had elective general surgery between October 2013 and April 2017, community dwelling, aged 19 years or older and could complete survey forms. The outcome measure was wait time, defined as the number of weeks between being registered for elective general surgery and surgery date. Results: One thousand three hundred twenty elective general surgery participants were included in the study. The response rate among eligible patients was 53%. Regression analyses found no statistically significant association between patients’ wait time with SES, adjusting for health status, cancer status, surgical priority level, comorbidity burden and demographic characteristics. Participants with proven or suspected cancer status had shorter waits relative to participants waiting for surgery for benign conditions. Participants with at least one comorbidity tended to experience shorter waits of approximately 5 weeks (p < 0.01). Pre-operative pain or depression/anxiety were not associated with shorter wait times. Conclusions: Although this study found no relationship between SES and surgical wait time for elective general surgeries in the study hospitals, patients in lower SES categories reported worse health when assigned to the surgical queue.

description: In this thesis we investigate the acquisition of V-movement in matrix and subordinate clauses and its consequences for the position of the subject in the Spanish interlanguage of native speakers of English and French. We have specifically investigated whether or not there is parameter resetting when the value of the parameter differs in the L1 and the L2. In order to determine our subjects' non-native competence we have obtained cross-sectional data in the form of oral spontaneous production and grammaticality judgments. The results suggest that learners do not reset the V-movement parameter when they acquire Spanish as a second language, a conclusion which is in line with an emerging view about parameter resetting in second language acquisition.
Suboptimal congestion control laws for TCP-RED dynamics in computer networks

Year: 2007
Subjects: subject: Engineering, System Science.
subject: Computer Science.

description: Based on a dynamic model that simulates the behavior of TCP flows and active queue management (AQM) scheme two specific congestion avoidance modes, feedback control law and real time control law, have been presented respectively in the thesis. The control laws proposed monitor the status of buffers and multiplexor of the router and detect incipient congestion by sending warning signals to the sources. In our work, the AQM scheme can be modeled as a feedback control system governed by stochastic differential equations driven by a doubly stochastic point process with intensities being the controls. Besides, the AQM scheme can also be modeled as a real time control system in which the state of the router is monitored online and an optimal control must be executed in real time for each of sampled time intervals. Key Words: Feedback Control, Real time Control, RED, Dynamic Model, TCP, AQM.

description: Photoelectric, photographic and CCD UBV photometry, spectroscopic observations and star counts are presented for the open cluster Berkeley 58 to examine a possible association with the 4.37 d Cepheid CG Cas. The cluster is difficult to separate from the early-type stars belonging to the Perseus spiral arm, in which it is located, but has reasonably well-defined parameters: an evolutionary age of ∼108 yr, a mean reddening of E(B−V) (B0) = 0.70 ± 0.03 s.e. and a distance of 3.03 ± 0.17 kpc (V0−MV= 12.40 ± 0.12 s.d.). CG Cas is a likely cluster coronal member on the basis of radial velocity, and its period increase of +0.170 ± 0.014 s yr−1 and large light amplitude describe a Cepheid in the third crossing of the instability strip lying slightly blueward of strip centre. Its inferred reddening and luminosity are E(B−V) = 0.64 ± 0.02 s.e. and 〈MV〉=−3.06 ± 0.12 . A possible K supergiant may also be a cluster member.
Large eddy simulation (2D) using vortex-in-cell and filtered density function for isothermally reacting and thermally stratified mixing layers
Creators: name: Siklawi, Charbel
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2009
Subjects: subject: Engineering, Mechanical.

description: A large eddy simulation based on the filtered vorticity transport equation has been coupled with the filtered mass weighted density function transport equation. The filtered vorticity transport has been formulated using the diffusion-velocity method and then solved using the vortex-in-cell scheme in conjunction with both Smagorinsky and dynamic eddy viscosity subgrid scale models for an anisotropic flow. The transport equation for filtered mass weighted density function is solved using the Lagrangian Monte-Carlo method. The methodology has been tested on both chemically reacting with no heat release and thermally stratified spatially growing mixing layers. It is shown that mixing has a greater effect on scalar field within the vortex structure as compared to the braid regions. Also for high Damkohler number (Da), the reaction zones are mainly limited to the thin reacting interfacial zones, i.e. the contact zone between the reactants, whereas for low Da, the reacting zones are spread as reacting pockets within the vortex structure. The effect of vorticity-temperature interaction, i.e., the volumetric expansion and baroclinic vorticity generation, on the flow field is also investigated by mixing a cold and a hot stream with temperature differences of 0, 5, 10, 30 and 50°K. The mixing layer is destabilized earlier and the pairing of vortical structures is reduced as temperature difference is increased. The characteristics of the flow field, i.e. the vorticity contours, the mean velocity, root-mean-square velocity fluctuations and negative cross-stream correlations are discussed. Also, the characteristics of the scalar field, i.e. the mean scalar profiles, root-mean-square scalar fluctuations profiles and filtered probability density function are presented.

description: We construct Tully-Fisher relations (TFRs), from large samples of galaxies with spatially-resolved H alpha emission maps from the K-band Multi-Object Spectrograph (KMOS) Redshift One Spectroscopic Survey (KROSS) at z approximate to 1. We compare these to data from the Sydney-Australian-Astronomical-Observatory Multi-object Integral-Field Spectrograph (SAMI) Galaxy Survey at z approximate to 0. We stringently match the data quality of the latter to the former, and apply identical analysis methods and sub-sample selection criteria to both to conduct a direct comparison of the absolute K-band magnitude and stellar mass TFRs at z approximate to 1 and 0. We find that matching the quality of the SAMI data to that of KROSS results in TFRs that differ significantly in slope, zero-point and (sometimes) scatter in comparison to the corresponding original SAMI relations. These differences are in every case as large or larger than the differences between the KROSS z approximate to 1 and matched SAMI z approximate to 0 relations. Accounting for these differences, we compare the TFRs at z approximate to 1 and 0. For disk-like, star-forming galaxies we find no significant difference in the TFR zero-points between the two epochs. This suggests the growth of stellar mass and dark matter in these types of galaxies is intimately linked over this approximate to 8 Gyr period.
A query system for XML data streams and its buffer reduction based on semantics
Creators: name: Yang, Chi
Publisher: name: Swinburne
Year: 2024

description: The XML data sources are of marvellous diversity. Available XML data ranges from small Web pages to ever-growing applications, such as biological data, astronomical data, commercial data, and even to rapidly changing and possibly unbounded streams which are often encountered in Web data integration and online publish-subscribe systems. The ubiquity of XML data stream animates the importance to develop XML data stream query systems theoretically and practically. Currently, queries on XML data stream is still an active research area. The last years witnessed the work and contribution from both practitioners and theoreticians towards effective query evaluation against XML data streams. Due to the unique features of XML data stream model, several aspects of data management need reconsideration, such as buffer management, query optimization and block operation processing. With respect to current methods for query evaluation over XML data stream, adoption of certain types of buffering techniques is inevitable. Under lots of circumstances, the buffer size may increase exponentially, which can cause memory bottleneck. Some theoretic research proving a concurrency lower bound to describe this type of bottleneck has been given. Some optimization techniques have been proposed to solve the problem. However, the research on semantic query optimization (SQO) for XML data streams is still at its early stage. In particular, the application of semantic information to optimize the buffering usage during the query evaluation leaves lots of room for researchers to maneuver. The work reported in this thesis focuses on the study of query processing for XML data streams and effective buffer management by exploring semantic information. The first contribution is a SAX-based XML stream query evaluation system, which explores query optimization opportunities based on semantics to reduce the unnecessary buffer scale to a level less than the theoretic lower bounds. The second contribution is that we get some effective semantic rules according to our criterion for rule exploration. Algorithms before and after the application of the semantic query optimization rules are presented and compared. The architecture of our system which deploys semantic optimization technique according to predefined stream optimization rules is shown. The third contribution is the further discussion on the application of SQO rules for block operators and aggregation functions. Experiments are conducted to demonstrate the system performance gains after the deployment of SQO techniques. The experiment results show that the algorithms deploying semantic rules individually and collectively all significantly outperform the lower bound algorithm that does not consider semantic information.
On the requirements for protocol conversion.

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

Subjects: subject: Computer Science.

description: The gateways that connect networks must deal with heterogeneity in the protocols they support. One approach is to implement a protocol converter on the gateway to translate and synchronize the messages between different protocols in such a way that the required service of the common upper layer protocol is satisfied. In this thesis we explore one of the main problems of heterogeneous network interconnection at a gateway: the protocol conversion problem. The protocol conversion problem deals with the rules for message exchanges and the behavioral concerns that deal with the reconciliation between different protocol message formats, their orderings and the service they provide. This thesis provides a formulation of the protocol conversion problem in a general framework. Formal methods have been proposed for the protocol conversion problem based on a common specification model for protocols: the Communicating Finite State Machine (CFSM) model. These formal methods require that the conversion requirements be defined formally as well. There are two types of conversion requirements: protocol-level conversion requirements that specify the translation requirements and the synchronization requirements of the protocol converter in terms of peer protocol messages, and service-level conversion requirements that specify the service requirements in terms of the service primitives of the conversion system. Based on the presented formulation of the protocol conversion problem, in this thesis an approach to synthesize service-level conversion requirements is proposed. Furthermore, an approach to synthesize the protocol-level conversion requirements that capture the semantic relation between the two protocols as it is specified by the service-level conversion requirements is proposed. It is then shown that existing formal methods can be used to synthesize a protocol converter using the constructed protocol conversion requirements. (Abstract shortened by UMI.)

description: OFDM-based radar schemes are promising candidates to solve inherent limitations of frequency-modulated schemes. However, for a practical implementation in the automotive environment with an increasing amount of sensors and disturbances, not only the performance of the modulation scheme is important but also how it can perform in coexistence with other modulation schemes. In this paper, measurements are shown to investigate the impact of chirp-sequence-based sensors on a wideband OFDM radar. Furthermore, a straightforward method to mitigate and eliminate the interference on the receive signal is presented that allows reliable target detection even under severe chirp-sequence interference.

Stages of economic development and business orientations: their impact on business education
Creators: name: Spark, Mike
Publisher: name: Swinburne
Year: 2024

description: As overall demand is exceeded by supply, both through an increase in manufacturers and more outputs through manufacturing efficiency, many firms will be forced to adopt the ‘Selling’ orientation, whereby resources are diverted to sales efforts in order to dispose of inventoried product and provide funds for further manufacturing efforts. At some stage (perhaps when the above strategies are assessed to be not working), a smart firm will consider adopting a ‘Marketing’ orientation, in which the organisation conducts market research to find out what the market wants and/or needs, and then (and only then!) produces both tangible and intangible market offerings (‘products’ in marketing terms) to specifically satisfy their needs and wants. This is not only a better longer-term approach to corporate survival and making profits but is also less risky (as one’s production output is potentially pre-sold, simply because it is made to satisfy pre-ordained or perceived customer expectations).

description: Anaerobic digestion (AD) is a bio-based solution designed to convert organic materials into renewable energy and other products, such as soil improver and organic fertiliser. AD is widely used in practice, with facilities at many thousands of sites worldwide: in Europe alone, more than 20,000 full-scale plants were in operation in 2022 [1]. The underlying biological processes are complex, and multiple options exist to steer the AD process towards optimised performance and a desired set of outputs in terms of energy and material flows. This puts AD in a prominent position with research agendas aiming for more sustainable resource management. Its ability to generate high-value products from organic wastes and residues is a key strength. The Special Issue on “New Frontiers in Anaerobic Digestion (AD) Processes” was initiated to explore recent developments and advanced concepts related to the valorisation of biomass via the application of AD. Fourteen submissions are included in the Special Issue, and each of these publications contributes towards unlocking the full potential of AD. Five thematic clusters to advance AD can be identified based on the included publications: - Understanding and monitoring the AD process; - Making substrates available and increasing the efficiency of the AD process; - Inspiring trust in non-academic stakeholders to adopt AD in practice; - Supporting decarbonisation of the energy system through hydrogen and biomethane; - Obtaining more value from a single unit of biomass.

The Effect of Stimulus Area on Global Motion Thresholds in Children and Adults
Creators: name: Meier, Kimberly
name: Giaschi, Deborah
Publisher: name: Multidisciplinary Digital Publishing Institute
Year: 2019

description: Performance on random-dot global motion tasks may reach adult-like levels before 4 or as late as 16 years of age, depending on the specific parameters used to create the stimuli. Later maturation has been found for slower speeds, smaller spatial displacements, and sparser dot arrays. This protracted development on global motion tasks may depend on limitations specific to spatial aspects of a motion stimulus rather than to motion mechanisms per se. The current study investigated the impact of varying stimulus area (9, 36, and 81 deg²) on the global motion coherence thresholds of children 4–6 years old and adults for three signal dot displacements (∆x = 1, 5, and 30 arcmin). We aimed to determine whether children could achieve mature performance for the smallest displacements, a condition previously found to show late maturation, when a larger stimulus area was used. Coherence thresholds were higher in children compared to adults in the 1 and 5 arcmin displacement conditions, as reported previously, and this did not change as a function of stimulus area. However, both children and adults performed better with a larger stimulus area in the 30 arcmin displacement condition only. This suggests that immature spatial integration, as measured by stimulus area, cannot account for immaturities in global motion perception.

description: Modelling and simulation play an essential role in developing, optimizing and understanding the steps involved in the production of polymers. A simulator was designed in order to model free-radical bulk and solution homopolymerizations, as well as multi-component polymerizations. Several optional models were incorporated in to the simulator, such as several glass transition temperature models, and the penultimate model. Java(TM) was selected as the programming language because of its object-oriented nature, providing high flexibility and ensuring easy extension of the code. Once the simulator was validated against experimental data and another simulator, it was used to model three systems: butyl acrylate/vinyl acetate (BA/VAc), styrene/butyl acrylate (Sty/BA), and butyl acrylate/methyl methacrylate/vinyl acetate (BA/MMA/VAc).

description: Les pouvoirs de la Couronne en matiere de defense et de controle sur les Forces armees sont principalement issus de la prerogative dont les limites sont souvent ambigues et incertaines. Bien que certaines regles legislatives encadrent le recours a la force militaire, elles sont peu nombreuses et d'une application limitee. Ceci est particulierement vrai pour l'usage de la force militaire en temps de paix pour maintenir l'ordre et la securite publics. Ayant connu une lente evolution au rythme du developpement de la common law, les pouvoirs modernes fondant le recours aux Forces armees en temps de paix pour des taches non traditionnelles, soit pour l'application des lois ou pour offrir une assistance technique ou humanitaire aux autorites civiles, ne sont pas illimites. Bien que la forme du droit attribue une tres grande marge de manoeuvre a la Couronne quant au recours a la force militaire en temps de paix, ce pouvoir n'est pas illimite. L'ambiguite des regles de droit qui regissent la defense de l'Etat et le recours en temps de paix aux Forces armees canadiennes militent en faveur de l'adoption de dispositions legislatives plus precises et mieux adaptees aux besoins contemporains en matiere de defense interne.

description: This paper explores the theoretical basis and past research exploring what helps adults to learn effectively in the Adult Basic Education (ABE) setting. Information on eleven ABE-to-college transition programs was compiled through the Adult Transitions Longitudinal Study (ATLAS) data collection. Statistical analyses of the resulting program-level variables were conducted to examine their effect on transition course participants’ college outcomes. Four of the twelve variables analyzed were found to significantly impact the likelihood of participants enrolling in college and successfully earning at least three credits: 1) whether the program uses grades versus pass/fail marks; 2) whether the program has a documented student life skills course component; 3) whether the program assigns participants a mentor (either a staff member or past transition program graduate) and; 4) whether the transition course teacher(s) provide(s) students with high or low levels of written feedback on their homework and essays. This evidence may help transitions programs and educators to understand and emphasize the components of ABE-to-college courses that have the most impact on student persistence in higher education.

description: It is known that exposure to excess saturated fatty acids, especially palmitate, can trigger cellular stress responses interpreted as lipotoxicity. The effect of excessive free fatty acids on oxidative phosphorylation capacity in myoblasts of patients with the m.3243A>G mutation was evaluated with the mitochondrial (Mito) stress test using a Seahorse XF96 analyzer. ß-oxidation, measured with the Seahorse XF96 analyzer, was similar in patients and controls, and reduced in both patients and controls at 40 °C compared to 37 °C. Mito stress test in the absence of fatty acids showed lower values in patients compared to controls. The mitochondrial activity and ATP production rates were significantly reduced in presence of palmitate, but not of oleate in patients, showing a negative effect of excessive palmitate on mitochondrial function in patients. Diabetes mellitus is a frequent symptom in patients with m.3243A>G mutation. It can be speculated that the negative effect of palmitate on mitochondrial function might be related to diacylglycerols (DAG) and ceramides (CER) mediated insulin resistance. This might contribute to the elevated risk for diabetes mellitus in m.3243A>G patients.

Damit werden Informationsgrundlagen geschaffen um Bergbauunternehmen und Investoren einen Überblick über die Entwicklung ihres Projektportfolios zu geben, und staatlichen Einrichtungen eine nationale Rohstoffplanung zu ermöglichen. Für Ressourcen in anthropogenen Quellen wie Halden, Deponien, Gebäuden, Konsumgütern oder auch industriellen Prozessen gab es bis vor kurzem keine international anerkannte Methode zur Vorratsklassifikation. Die Rahmen-Vorratsklassifikation der Vereinten Nationen (R-VK), mit ihrer auf anthropogene Ressourcen erweiterten Anwendungsmöglichkeit, füllt nun diese Lücke. Dieses Arbeitspapier gibt einen historischen Abriss über die Entwicklung der R-VK und zeigt deren gesellschaftlichen Anspruch im Wandel der Zeit auf, stellt die Spezifikationen der R-VK für anthropogene Ressourcen und deren Nutzen vor, und zieht Schlussfolgerungen in Hinblick auf zukünftige Entwicklungsmöglichkeiten.

description: The vapor phase air oxidation of propene and 2-methylpropene to acrolein and methacrolein was investigated in an isothermal integral flow reactor at atmospheric pressure between 300 and 500°C. The skeleton catalyst (copper oxide) supported on pumice stone or inactivated alumina was modified in a constant and continuous supply of trace amounts of selenium, sulfur, bromine, chlorine and iodine, all having the electronegativities higher than that of copper. The effect of various process variables, namely the weight ratio of modifier to olefin in the feed, the feed ratio of oxygen to olefin, reaction temperature and the reciprocal of space velocity, on the conversion of olefin and the product distribution was determined by gas chromatography. It was found that in the presence of small amounts of these modifiers, the selectivity for unsaturated aldehydes increased very substantially. The promotional effects of different modifiers are compared and discussed. It was observed that the weight ratio of modifier to olefin in the feed is the most important variable in the selective oxidation of olefin, and that its optimum value is in the range of 0.0005 to 0.0015 for the oxidation of 2-methylpropene. The catalytic oxidation of methacrolein over the same catalyst in the presence and absence of a chlorine modifier was also studied. The results indicate that the promotional effect of the modifier is mainly due to its successfully suppressing the further oxidation of aldehyde to the undesired products. The active phase of the catalyst for the selective oxidation of olefin was found to be cuprous oxide by X-Ray diffraction studies. The Electronic Theory of Catalysis has been modified to explain the results and a mechanism is proposed. It has been suggested that the charged oxygen and olefin are selectively adsorbed on the catalyst surface and that the partial oxidation of olefin is a p-type reaction, and its further oxidation to carbon dioxide is an n-type reaction under the optimum conditions. Out of the several models proposed for the oxidation of 2-methylpropene over chlorine modified copper oxide catalyst, the most suitable one appears to be the one in which the rate-determining step is the surface reaction between adsorbed olefin and oxygen on different active sites. The rate of reaction can be expressed by the equation r=KSKHPH 1+KHPH+KMPM ˙KOPO1+K OPO Where KS, KH and KM are temperature dependent constants.

description: We employ N-body, smoothed particle hydrodynamic simulations, including detailed treatment of chemical enrichment, to follow a gas-rich merger that results in a galaxy with disk morphology. We trace the kinematic, structural, and chemical properties of stars formed before, during, and after the merger. We show that such a merger produces two exponential disk components, with the older, hotter component having a scale length 20% larger than the later forming, cold disk. Rapid star formation during the merger quickly enriches the protogalactic gas reservoir, resulting in high metallicities of the forming stars. These stars form from gas largely polluted by Type II supernovae, which form rapidly in the merger-induced starburst. After the merger, a thin disk forms from gas that has had time to be polluted by Type Ia supernovae. Abundance trends are plotted, and we examine the proposal that increased star formation during gas-rich mergers may explain the high alpha-to-iron abundance ratios that exist in the relatively high-metallicity, thick-disk component of the Milky Way.

description: The interrelationship between tourism development and polar environmentsbecame a hot topic in the last decades. Since climatic changes lead toaltered ecosystems including the alteration of species, composition in areas withprevious icy and hostile conditions, especially the use of polar landscapes, cameinto touristic focus. However, the Southern Ocean surrounding Antarctica has beenan exceptional destination to experience nature and follow the path of adventurerssince its discovery. To fulfill the Protocol on Environmental Protection to theAntarctic Treaty (Environmental Protocol) with the aim to protect the Antarcticarea as well as possible, the procedure of granting a permit for tourism activitiesis well developed in German legislation. For decades, Germans have accountedfor more than 10% of all tourists enjoying the special landscape during a cruiseto Antarctic coasts. This puts them in the top 3 of the world together with Americanand British tourists. Since 2000, the German Federal EnvironmentAgency recordedinformation on German tourist activities in the area of Antarctica from yearly postvisitreports. These data may support discussions on possible steps toward requiredregulations for polar tourism in the near future. Some aspects of land-based tourismon the Antarctic continent, and especially on the Antarctic Peninsula and islandsnearby, are highlighted with regard to the potential consequences within the frameof environmental protection and climate change. Due to the lack of knowledgewhich impedes thoroughly environmental assessments for all touristic activities,the German Federal Environment Agency aims to encourage research and politicalinstitutions to support the development of a concept of sustainable tourism for theAntarctic Treaty area.Quelle: German Tourism Activities in the AntarcticArea: A Governmental Perspective.

Study of bus control strategies by computer simulation.

Subjects: subject: Engineering, Civil.

description: In this thesis, a simulation model used to simulate the running of buses on a single route, OC Transpo route 95, is studied. The model is implemented on a platform different from its original design at the University of Ottawa, and validation experiments are performed. For the most part, the model seems valid, although some additional calibration is recommended. New headway-based bus control strategies are presented and compared with other known control strategies. The statistical analysis and comparisons of those control strategies are based on the testing results obtained from the simulation model. The new headway control policies (called "Message Board" and "hybrid" policies) are shown to provide better service reliability in terms of less variable headway for the high-frequency route 95. Finally, a prototype of a knowledge-based system for real-time bus control purposes is developed and tested on the simulation model. The prototype is shown to be an interesting alternative for real-time bus control: it can effectively interface with the simulation model and perform real-time service control. This prototype will be a building block in the development of a more complete knowledge-based system capable of implementing more complex real-time service control policies in the hope of providing assistance to human controllers.
Neuroendocrine regulation of secretogranin-II (SgII) expression in the goldfish pituitary.

description: Secretogranin-II (SgII) is a secretary protein involved in the regulated secretory pathway of endocrine and neural cells. Preliminary evidence has suggested a role for it in reproductive function. The objectives of our studies were to elucidate how SgII expression is regulated within the goldfish reproductive system in an attempt to shed some light on its possible actions. Goldfish are a seasonally reproducing species with an annual cycle. The pituitary SgII expression levels fluctuate with the reproductive cycle. Sex steroids are not directly responsible for the cyclicity of SgII expression, nor do they regulate it at any time of the year. On the other hand, gonadotropin-releasing hormone (GnRH), the principal stimulatory factor of the reproductive system upregulates SgII expression. Testosterone suppresses the stimulatory effect of GnRH at certain stages of the reproductive cycle. Many other studies are necessary to fully comprehend the regulation of SgII within the reproductive system and whether it has any concrete functions therein.
Behavioural protocol representation and adaptation in a service composition framework

description: Service Oriented Architecture (SOA) is a paradigm for building software applications from loosely-coupled services. Building large applications often involves combining services into bigger ones. This process is known as service composition. In the dynamic, open and distributed environments of SOA, services are not always available and new services are introduced that might provide other characteristics that are more beneficial to the current system than the existing ones. In order to utilise different services, a service composition framework needs to allow its constituent services to be substituted and ensure that the services involved in the composition interact with each other in a compatible manner both in terms of functionality and sequence of exchanged messages (or behavioural protocol). In this thesis, we propose a service composition framework that has three capabilities: (i) specifying behavioural protocols among services and offering support for behavioural protocols including: aggregation of protocols, consistency checking and run-time protocol monitoring, (ii) checking compatibilities of potential services, and (iii) proposing adaptor patterns to alleviate the potential incompatibilities between services and the specified required sequence of interactions. Our service composition framework is built based on the Role Oriented Adaptive Design (ROAD) framework. Required sequences of interactions are defined by using a declarative pattern-based specification, the Interaction Rule Specification (IRS). The compatibilities of services are checked by a mechanism involving three steps: converting IRS descriptions to Finite State Automata (FSAs), converting services’ behavioural specifications (e.g. in OWL-S) to FSAs, and finally analysing the resulting FSAs to indentify compatibilities of potential services. In the case that services are incompatible to the required sequence of interactions, we propose three adaptation patterns that can be used to alleviate mismatches. The run-time overheads of behavioural protocol’s conversion to FSA and analysis are also evaluated. By supporting automated checking of behavioural compatibilities between services and providing adaptor patterns to address the identified behavioural mismatches, this thesis presents a further step towards automated service composition.
