Creators: name: Siswoyo Jo, Riady
Publisher: name: Swinburne
Year: 2024

description: This thesis presents a fundamental study on the propagation of finite-amplitude pressure waves in aerosols, which is commonly encountered in an extensive range of physical scenarios, from environmental study of atmospheric aerosols, to powder processing and aerospace engineering applications. This research involves developments of mathematical model, numerical method and parametric study to investigate the effects of various aerosol and wave parameters on the evolution and energy dissipation of the waveforms. The developed model contributes to current understanding of relevant physical phenomena and therefore provides new insights for researchers and engineers in their respective areas.

description: Network coding is an emerging technology that intelligently exploits the store/forward nature of routers to increase the efficiency of the network. Though the concept works in theory, the segregation of coding and routing decisions makes them inapplicable in almost any practical environment. Coding-aware routing takes the network coding a step further to lessen its disadvantages by allowing interlayer communication while making routing decisions. However, most of the existing work exploits coding benefits only for fixed wireless networks, making them dependent on the types of network medium, topology and mobility and thus inapplicable for wired and mobile Ad Hoc networks. The aim of this thesis is to present a generalized algorithm that can detect any possible coding opportunity in a network of any medium, topology and mobility while making routing decisions. We have tested and evaluated our algorithm in six different network topology settings i.e. small wired, big wired, small Ad Hoc network with regular trajectories, big Ad Hoc network with regular trajectories, small Ad Hoc with random trajectories and big Ad Hoc with random trajectories. Improved performance in network throughput, mean queue size and mean end-to-end delay confirms the validity of our algorithm.

Angular momentum in astrophysical discs and its impact on galaxy evolution
Creators: name: Stevens, Adam Robert Hugh
Publisher: name: Swinburne
Year: 2024

description: In this thesis, I develop models for how galaxies form and evolve. I focus on galaxies that have disc-like structure, outlining the fundamental importance of angular momentum in their formation and evolution. My model provides the most detailed accounting of this to date. I compare and contrast this and other models to state-ofthe- art supercomputer simulations of the entire growth of structure and galaxies throughout the Universe. I also use General Relativity to model how black holes can grow by accreting gas. This thesis contributes to mankind’s efforts to understand how the Universe came to be the way we observe.

description: Biodiesel is rapidly growing as a fuel of interest due to the various advantages it has over conventional diesel fuel. While the pros – non-toxic, biodegradable, low green house gas emissions seem advantageous, the major issue that plagues the use of biodiesel is its cold weather operability. Biodiesel can present challenges in cold-weather operation, because certain of its constituent compounds can form precipitates in the fuel. These precipitates can cause undesired effects like plugging of fuel filters and deposits. This issue has been attributed to the presence of impurities (mostly saturated monoglycerides, di-glycerides, soap etc) in biodiesel and has been discussed in the literature. There is a move by users and standards associations to implement more stringent norms and quality control to avoid problems in the widespread use of biodiesel. This study involves ways to reduce MG’s in biodiesel by mitigating to a greater extent the possibility of side reactions (formation of soap). The effect of selective transesterification of oil as a function of alcohol, temperature and catalyst concentration was also studied. Although saturated MG’s with high melting points are a greater source of deposits, it can be hypothesized that the polymorphic nature of unsaturated Monoglycerides could also be contributing to cold flow issues. It is hence vital to make sure the biodiesel is free from all forms of monoglycerides. It was also seen that there is very little specificity of selection of fatty acid types in the transesterification reaction and that the amount and type of MGs present in the biodiesel is reflected by the relative amount of fatty acids types present in the oil. In biodiesel derived from Canola oil, a preponderance of monoolein was found for all runs. The initial runs carried out as a two stage process using the membrane followed by batch reactor gave very low MG concentrations, well below ASTM standards.

description: Avec la concentration de la propriété des entreprises de presse et la convergence du contenu et des ressources, les journalistes voient leur liberté professionnelle et leur autonomie de travail diminuer au profit de la liberté des entreprises de presse. Dans cette optique, notre projet de recherche se penche sur la question de l’impact du contexte organisationnel des entreprises de presse sur la qualité de l’information. Nous avons effectué une étude de cas qui compare le contenu d’articles publiés par un même groupe de journalistes au Journal de Montréal et à ruefrontenac.com, un site d’information qu’ils ont créé durant leur conflit de travail. Notre hypothèse était que la qualité de l’information était meilleure sous ruefrontenac.com qu’au Journal de Montréal parce que les journalistes y possédaient plus de liberté. Nous avons effectué des entrevues semi-dirigées avec 10 journalistes qui ont travaillé pour ces deux organes de presse et nous avons comparé la qualité de l’information d’articles qu’ils y ont publiés. Les résultats obtenus ont confirmé notre hypothèse de départ et ont indiqué que le principal indicateur affecté par le changement de contexte organisationnel était celui de l’intérêt public. Cette étude est pertinente et contribue à l’avancement des connaissances, puisqu’elle met en lumière comment différents contextes de travail peuvent affecter la qualité de l’information, le droit d’accès du public à l’information et, par le fait même, la démocratie.
Fresh and Dry Weight Relations Are Predictors of Cycas micronesica Seed Age

Year: 2020

description: Cycas micronesica is a foundation species in several Micronesian islands and its seeds have been a historical source of starch for the island residents. The species has become endangered by invasive specialist insect herbivores and conservationists struggle with the inability to estimate the age of observed seeds. To inform this agenda, we evaluated numerous Cycas micronesica seed traits to determine if any exhibited a relationship with age and a substantial change in absolute value. Of the 30 direct and derived seed traits that we evaluated, most of them were non-linear and exhibited minimal change after about 12 months in age. The only traits that emerged as unambiguous estimators of age were the quotients derived as gametophyte fresh weight/total seed fresh weight and sarcotesta dry weight/sclerotesta dry weight. These two simple metrics can be used to accurately estimate seed age for this arborescent cycad species.
Physical Modelling of Pier Scour in a Constricting Channel
Creators: name: Ly, Jim
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2014

description: Experiments were completed in order to examine the effects of combined constriction and pier scour. Scour is cited as being a leading cause of bridge failure. It was found that in cases where both constriction and pier scour are present, the sum is greater than the linear addition of each individual case. This is contrary to the current industry assumption which states that the total depth of scour is the linear sum of the constriction and pier scour depth. Velocimetry and scour data were collected enabling comparisons to be made in order to determine how the flowfield influences the equilibrium scour conditions. In addition, experiments were performed examining the effect that the pier shape has on the scour depth and distribution. Since the results are contrary to the assumption used in industry, they are especially important and may help reduce future bridge failures.

description: The scope of access to justice in environmental matters in Germany is determined by European and International provisions. Since the ratification of the Aarhus Convention (AC) Germany is bound to this system of legal protection and guarantee of participatory rights. Moreover the provisions of Art. 9.2 AC have been implemented as European law especially through Art. 11 EIA-Directive (2011/92/EU) and Art. 25 IPPC-Directive (2010/75/EU). The implementation of these international and European provisions into the German legal system has partially led to difficulties: On the one hand its content and scope are controversial to a certain degree. On the other hand the objective to improve the execution of environmental law provisions must be achieved in accordance with the traditional German legal system of administrative law. Therefore this study examined legal questions on access to justice â€Ì of environmental-NGOs, individuals and municipalities - and the extent and the intensity of the judicial review which are of special im-portance for the implementation process of the Aarhus Convention in Germany. Hence the German legal debate as of October 2016 was analysed and on some selected legal aspects a comparative study concerning the national legal systems of France, Italy, Poland, Sweden and the United Kingdom was conducted.

description: The desire to obtain value and justify investments from the different Information Systems in place in organizations has been around for a long time. Organizations constantly theorize and implement different approaches that provide some sort of alignment between their different business objectives and Information Systems. Unfortunately, the environments in which these organizations operate are often dynamic, constantly changing with influence from external and internal factors that require continual realignment of the Information Systems with business objectives to provide value. When businesses evolve, leading to changes in business requirements, it is hard to know what direct Information System changes are needed to respond to the new requirements. Similarly, when there are changes in the Information System, it is not often easy to discern which business objectives are directly affected. Whilst the different Enterprise Architecture frameworks available today provide and propose some form of alignment, in their implementation, they do not show links between business objectives and Information Systems, i.e., indicating what Information System is directly responsible for different business objectives thereby allowing for anticipation and support of changes as the business evolves. This thesis utilizes insights from Business Intelligence and uses the User Requirements Notation (URN), which enables modeling of business processes and goals, to provide a framework that exploits links between business objectives and Information Systems. This Business Intelligence - Enabled Adaptive Enterprise Architecture framework allows for anticipating and supporting proactively the adaptation of Enterprise Architecture as and when the business evolves. The thesis also identifies and models levels within the enterprise where responses to change as the business evolves are needed and the ways the changes are presented. The tool-supported framework is evaluated against the different levels and types of changes on a realistic Enterprise Architecture at a Government of Canada department, with encouraging results.
New adaptive image sequence coding scheme using Kohonen's SOFM
Creators: name: Andrew, Lachlan L. H.
name: Palaniswami, Marimuthu
Publisher: name: Swinburne
Year: 2024

description: This paper presents a novel adaptive vector quantization scheme based on the SOFM neural network. All adaptation is performed directly from the quantized image with no explicit adaptation information transmitted or stored. Thus the network learns an input distribution it has never actually seen. Training sets are generated from the received image by scaling the image to approximate the statistics of the original image and selecting blocks in such a way as to capture edges and other image features. This data is fed to a SOFM neural network to update the codebook. A new method is also presented for ensuring that all neurons are well used, by estimating directly from the quantized image how much distortion each neuron introduces. The ability of this scheme to adapt successfully is verified by simulation.

description: The success of the internet over last few decades has mainly depended on various infrastructure technologies to run distributed applications. Due to diversification and multi-provider nature of the internet, radical architectural improvements which require mutual agreement between infrastructure providers have become highly impractical. This escalating resistance towards the further growth has created a rising demand for new approaches to address this challenge. Network virtualization is regarded as a prominent solution to surmount these limitations. It decouples the conventional Internet service provider’s role into infrastructure provider (InP) and service provider (SP) and introduce a third player known as virtual network Provider (VNP) which creates virtual networks (VNs). Resource discovery aims to assist the VNP in selecting the best InP that has the best matching resources for a particular VN request. In the current literature, resource discovery focuses mainly on static attributes of network resources highlighting the fact that utilization on dynamic attributes imposes significant overhead on the network itself. In this thesis we propose a resource discovery approach that is capable of utilizing the dynamic resource attributes to enhance the resource discovery and increase the overall efficiency of VN creation. We realize that recourse discovery techniques should be fast and cost efficient, enough to not to impose any significant load. Hence our proposed scheme calculates aggregation values of the dynamic attributes of the substrate resources. By comparing aggregation values to VN requirements, a set of potential InPs is selected. The potential InPs satisfy basic VN embedding requirements. Moreover, we propose further enhancements to the dynamic attribute monitoring process using a vector based aggregation approach.
Fertility, migration, and the ageing of the population: an analysis of the official projections
Creators: name: Betts, Katharine
Publisher: name: Swinburne
Year: 2024

description: As we move through the demographic transition, an older age structure is inevitable but future possible scenarios vary. Official Australian Bureau of Statistics (ABS) population projections for Australia show that, depending on varying assumptions for fertility and migration, the population in 2051 could be large and growing or the same size as it is today and declining. But an analysis of these same projections confirms earlier work which finds that migration has a minimal effect on the age structure. The paper analyses nine different population projections produced by the ABS, four in 1996 and five in 1998. The highest projection (fertility 1.85 and net migration 100,000) adds an extra ten million people by the year 2051 while the lowest (fertility 1.6 and nil net migration) adds none. This is a dramatic difference. But the effects of different fertility and migration assumptions on the median age in 2051 are also marked; changes in fertility have a strong effect while changes in migration have a weak effect. The projection which produces the lowest median age in 2051 for the least 'cost' in extra people added is the series which holds fertility at 1.85 and net migration at zero. Previous work shows that replacement fertility and nil net migration would be even more effective than this series. However, this combination of assumptions has not been used by the ABS.

description: In this thesis we study the impact of time in the analysis of social networks. To do that we represent a knowledge mobilization network, Knowledge-Net, both as a standard static graph and a time-varying graph and study both graphs to see their differences. For our study, we implemented some temporal metrics and added them to Gephi, an open source software for graph and network analysis which already contains some static metrics. Then we used that software to obtain our results. Knowledge-Net is a network built using the knowledge mobilization concept. In social science, knowledge mobilization is defined as the use of knowledge towards the achievement of goals. The networks which are built using the knowledge mobilization concept make more visible the relations among heterogeneous human and non-human individuals, organizational actors and non-human mobilization actors. A time-varying graph is a graph with nodes and edges appearing and disappearing over time. A journey in a time-varying graph is equivalent to a path in a static graph. The notion of shortest path in a static graph has three variations in a time-varying graph: the shortest journey is the journey with the least number of temporal hops, the fastest journey is the journey that takes the least amount of time and the foremost journey is the journey that arrives the soonest. Out of those three, we focus on the foremost journey for our analysis.

description: Dutch composer Peter Schat’s (1935-2003) pursuit of a compositional system that could generate and preserve intervallic relationships, while allowing the composer as much flexibility as possible to manipulate musical material, led him to develop the tone-clock system. Fundamentally comprised of the twelve possible trichords, the tone clock permits each to generate a complete twelve-tone series through the “steering” principle, a concept traced to Boulez’s technique of pitch-class set multiplication. This study serves as an overview of Schat’s tone-clock system and focuses primarily on the effects of the steering function in “Genen” (2000). Furthermore, I expand on the tone-clock system by combining transformational theory with Julian Hook’s uniform triadic transformations and my proposed STEER and STEERS functions, which express the procedures of the steering principle as a mathematical formula. Using a series of transformational networks, I illustrate the unifying effect steering has on different structural levels in “Genen,” a post-tonal composition.

description: It was hypothesized that superparamagnetic nanoparticles encapsulated in a silica shell with a fluorescent dye could be functionalized with axonal tracers and could be used for serial, non-invasive imaging with magnetic resonance imaging (MRI) for axon tract tracing. Nanoparticles functionalized with amine, octadecyl, silica, and biotinylated dextran amine were manufactured and characterized with MRI, scanning electron microscopy, and UV-visible, infrared, and fluorescence spectroscopy. Nanoparticle concentrations of 10 mM were not toxic to adult rat neural progenitor cells (NPCs) and labeled approximately 90% of cells. Nanoparticles were assessed for anterograde and retrograde tract tracing in adult rat models. With MRI and microscopy, the nanoparticles did not appear to trace axons but did provide an MRI signal for up to 3 weeks post implantation. While functionalized nanoparticles did not appear to trace axons, they are not toxic to NPCs and may be used as a MRI contrast agent in the neural axis.

description: We present a novel method for example-based simulation of fluid flow. We reconstruct fluid animation from physically based fluid simulation examples. Our framework shows how to decompose a given series of fluid motion example data into small units and then recompose them. We capture the properties of local fluid behavior by dicing the fluid motion example data into sequences of fragments, which have smaller volume and shorter length. We build a database out of these fragments, and propose a matching strategy to generate new fluid animation. To achieve highly efficient database query, we project our fragments onto lower dimensional subspace using Principal Component Analysis (PCA) approach, and construct our data structure as a kd-tree by treating each fragment as a point in this subspace. Our method has been implemented in synthesizing both two-dimensional (2D) and three-dimensional (3D) fluid’s velocity fields.

description: Purpose and methods: Effective parental education about newborn screening (NBS) may help to maximize the benefits and minimize the harms of screening. We investigated experiences, knowledge and opinions regarding NBS education among Ontario mothers. Mothers whose infants recently received NBS were invited to complete a mailed survey (n=1712). Results: Of the 750 participants, 93% recalled their infant receiving NBS, while 69% recalled receiving information about NBS. Of this group, fewer than 50% reported receiving information prenatally, yet a majority of mothers (64%) viewed this as the most important time for education. Those who received information prenatally reported higher satisfaction (OR 2.4). The 40% of mothers who recalled being informed about the meaning of results had higher knowledge about NBS (OR 2.7) and reported higher satisfaction (OR 4.2). Conclusions: Parental education about NBS could place greater emphasis on the prenatal period and on fostering understanding about the meaning of results.

description: Weather prediction models are, in fact, coupled earth-system models requiring accurate representation of land-surface processes to provide accurate atmospheric predictions. From continued evaluation of the NOAA HRRR weather prediction model, the RUC land-surface model (RUC LSM) has been refined yet more to improve near-surface temperature and moisture predictions. In this paper, we describe the RUC LSM changes since 2015 including improvements for evaporation and soil moisture processes, for snow-cover fraction processes, and of new land-use datasets including satellite-based green vegetation fraction not previously available. This resulted in improvements in predictions of near-surface air temperature and moisture.
Digital response in an all optical AND gate using parametric (x^(2) solitons
Creators: name: Collecutt, G. R.

Publisher: name: Swinburne
Year: 2024

description: The main problem with optical logic is that the operation of a logic gate that works on two inputs is essentially a nonlinear process, whereas electromagnetic waves in most media are solutions to the linear Maxwell equations; in most dielectrics light does not interact with itself. However, in recent years there has been considerable advances in the theory and manufacture of nonlinear optical media, which now opens a new and exciting range of possibilities for implementing all optical logic circuits. One such possibility is the implementation of an all-optical AND gate as proposed by Drummond et al. (1999). In this method the two optical inputs are collided noncollinearly in a dispersive parametric planar waveguide. Consider firstly type II interaction in which the pulses have orthogonal polarizations. If only one pulse at a time is injected into the waveguide then it simply disperses. Whereas if two pulses arrive simultaneously then when they collide a phase-matched second harmonic is generated that traps the original two fundamentals, forming a 2+1D spatiotemporal soliton, which propagates stably towards the logic true output. Finally, it is also apparent that when no pulse is present on either input then no output will be generated. In this fashion AND gate logic operation is achieved. For such 2+1D solitons to form the basic requirements are anomalous dispersion and (nearly) matched group velocities at the fundamental and second harmonic frequencies

description: This research focused on measuring permafrost patch size and related variables between Fort St. John, BC and Whitehorse, YT. Methods used included electrical resistivity tomography, climate monitoring, active layer measurement, analysis of historical aerial photos, and on-site near-vertical aerial imaging. Where permafrost is present along the transect, mean annual air temperature (2010-2014) varied from -3.3 ºC to -0.9 ºC, mean annual ground surface temperature from 0.7 ºC to 2.4 ºC and mean annual ground temperature from -0.3 ºC to 0.2 ºC (at TTOP). Permafrost patches are in the order of 10 – 50 000 m2 in area and there is a strong positive log-log relationship between patch area and maximum permafrost thickness. A conceptual model of permafrost patch size evolution under a warming climate is proposed. It is concluded that permafrost patch size depends on site-specific characteristics, the time since permafrost began to degrade and the local climate conditions.

description: In recent years, increasing attentions are paid on developing exceptional technologies for efficiently processing massive collection of heterogeneous data generated by different kinds of sensors. While we have observed great successes of utilizing big data in many innovative applications, the need on integrating information poses new challenges caused by the heterogeneity of the data. In this thesis, we target at geo-tagged data, and propose a cloud based platform named City Digital Pulse (CDP), where a unified mechanism and extensible architecture are provided to facilitate the various aspects in big data analysis, ranging from data acquisition to data visualization. We instantiate the proposed system using multi-model data collected from two social platforms, Twitter and Instagram, which include plenty of geo-tagged messages. Data analysis is performed to detect human affections from the user uploaded content. The emotional information in big social data can be uncovered by using a multi-dimension visualization interface, based on which users can easily grasp the evolving of human affective status within a given geographical area, and interact with the system. This offers costless opportunities to improve the decision making in many critical areas. Both the proposed architecture and algorithm are empirically demonstrated to be able to achieve real-time big data analysis.

description: Introduction/ Objectives: Stroke, the third leading cause of death in Canada, is projected to rise in the next 20 years as the population ages and obesity rates increase. Family caregivers fulfill pertinent roles in providing support for family members who have survived a stroke, from onset to re-integration into the community. However, the transition from rehabilitation to home is a crucial transition for both the stroke survivor and family caregiver. As the stroke survivor transitions home from a rehabilitation facility, family caregivers provide different types of support, including assistance with navigating the stroke rehabilitation system. They also are a constant source of support for the stroke survivor providing them with continuity during the transition. In this exploratory study we examined family caregivers’ perceptions and experiences navigating the stroke rehabilitation system. The theories of continuity care and complex adaptive systems were used to examine the transition home from hospital or stroke rehabilitation facility, and in some cases back to hospital. Methodology: Family caregivers (n=14) who provide care for a stroke survivor were recruited 4-12 weeks following the patient’s discharge from a stroke rehabilitation facility. Interviews were conducted with family caregivers to examine their perceptions and experiences navigating the stroke rehabilitation system. Directed content analysis was used to explore the perceptions of family caregivers as they reflected on the transitions home. The theories of continuity of care and complex adaptive systems were used to interpret their experiences. Results/Conclusions: During the transition home from a rehabilitation facility, family caregivers are a constant source of support, providing the stroke survivor with continuity. Emergent themes highlight the importance of the caregiving role, and barriers and facilitators that impact the role, and influence continuity of care. Also, supports and services in the community were limited or did not meet the specific needs of the family caregiver. The acknowledgment of the unique attributes of each case will ensure supports and services are tailored to the family caregiver’s needs. Mitigation of systemic barriers would also decrease complexity experienced at the micro-level in the stroke rehabilitation system, and better support the family caregiver during the transition home from a stroke rehabilitation facility.
The system psychodynamics of e-mail: a case study

Publisher: name: Swinburne

description: This thesis reports on a case study of e-mail related organisation dynamics in a medium sized, Australian consulting services organisation. The research explored the extent to which e-mail supported or inhibited the organisation's work, e-mail's application to management of the business and e-mail's use for purposes that were not obviously related to the business. The case is rendered particularly interesting because, for the nine-month duration of the fieldwork, the founder of this privately owned organisation was in the process of selling it to a much larger, publicly listed corporation and because, just after the fieldwork started, a restructure that related to the sale of the business was announced. The approach taken in the study was to regard the organisation as a complex system of interrelated parts, some human and some non-human and to consider e-mail as an integral component of its various sub-systems, as a means by which sub-systems were linked to each other and as a system in its own right. Understanding about e-mail's involvement in organisation dynamics was obtained through the experience of a group of eleven members of staff, who agreed to participate in the study and via my own experience of the organisation. The study was informed by the prior work of others in the fields of socio-technical systems, system psychodynamics and psychoanalytic concepts applied to organisations. Data was generated and analysed using psychoanalytically informed, action research based methods, involving individual and group interviews, field observations and access to e-mail messages, and through a cyclical process of hypothesis generation and testing, reflection, interpretation and feedback processes. The study revealed that the case study organisation, which had survived and grown successfully for many years, was being undermined by degenerative processes resulting from the changing ownership. As a result of the research process, which explored beneath the surface of observable behaviour and rational explanations to probe the effect of unconscious organisational processes, e-mail was found to have supported the sustaining dynamics associated with the organisation's success as an entrepreneurial endeavour, and to have fuelled the disintegration associated with the sale.

description: Le mythe et le théâtre entretiennent une relation qui demeure problématique. Si pour certains historiens le théâtre, dès ses origines, s’est inspiré des mythes en y puisant ses arguments, pour d’autres, c’est à la tragédie que les mythes doivent leur inscription dans l’Histoire. À notre époque, les héros mythiques sont toujours des références théâtrales obligées dont le traitement est très révélateur des intentions d’un auteur. C’est dans cette perspective et à la lumière de la mythocritique qu’est analysé l’hypotexte mythologique de plusieurs pièces de Michel Marc Bouchard et Michel Ouellette pour l’envisager ensuite comme un procédé de génétique textuelle. Cette approche a permis de mettre au jour les rapports qui lient les topoï de prédilection des deux dramaturges aux mythes de référence et de dégager l’évolution de leurs « mythes personnels » au travers de leur production.

description: Banking and insurance services are ideal candidates for electronic delivery (Evans and Wurster 1997 and Rayport and Sviokla 1995). It is unsurprising therefore to find that the financial services industry has been among the earliest adopters of electronic commerce solutions in the provision of those services. However that there is little empirical evidence that this trend is to any large degree a response to customer demand. This paper outlines some findings of a series of focus groups conducted with members of a large health insurance company in Australia. Key findings of this qualitative work were that while introduction of e-commerce applications to their service was not a key issue for customers, any such introduction would need to meet a range of serious customer concerns if it was to meet with their approval. Follow-up research revealed that subsequently, not only the fund in question but in fact all major funds had aggressively implemented Internet payment and claiming. The researchers recommend that detailed post implementation study is needed to identify the extent to which customer concerns have or have not been figured into the systems introduced. The case also illustrates the difficulty that can be encountered in execution of an apparently simple focus group recruitment task.

Wood Frame Construction

description: Wood-framed buildings have generally performed well during earthquake events, resulting in low fatality levels. However, various degrees of damage is still observed in these buildings during previous earthquakes. Lessons learned from the performance of wood frame construction in these earthquakes is led to an improvement in the design codes and construction practices over the past decades. But, the existing buildings are still vulnerable, since they were designed based on the older codes or constructed using old construction practices. Wood frame construction is the most common construction type in Canada, especially for single family dwellings. Most of these buildings are old, built prior to any modern seismic requirement, and have not been retrofitted against the damaging effects of earthquakes. Therefore, with a number of Canadians living in areas of high or moderate earthquake risk, there is a need to develop tools to assess the seismic vulnerability of the exiting wood-framed buildings in Canada. In the following thesis, a risk-based visual seismic assessment model and a screening tool (CanRisk) is developed, to assess the seismic vulnerability of existing wood frame construction in Canada. The model is dependent on the seismic hazard, building vulnerability, and building importance/exposure, which are integrated using hierarchical fuzzy rule based modeling. In the proposed seismic assessment model, fuzzy logic is used as a computing technique to capture the vagueness and uncertainty of a seismic vulnerability assessment, caused by subjectivity involved in the evaluation process. The hierarchical fuzzy rule based modeling used in this seismic assessment method is implemented in a prototype Matlab based program (CanRisk), which incorporates the Canadian seismic design practice based on the National Building Code of Canada (NBCC) and the Canadian site seismic hazard. A sensitivity analysis is conducted to test and verify the seismic assessment model and investigate the effects of various parameters on the outcome of the assessment. Also, in a case study, selected wood-framed buildings located in the city of Ottawa are evaluated using CanRisk, to demonstrate the applicability of the program.

description: Background: Patients living with chronic obstructive pulmonary disease (COPD) are at an increased risk of lung cancer. A common comorbidity of COPD is cardiovascular disease; as such, COPD patients often receive statins. This study sought to understand the association between statin exposure and lung cancer risk in a population-based cohort of COPD patients. Methods: We identified a population-based cohort of COPD patients based on having filled at least three prescriptions for an anticholinergic or short-acting beta-agonist (SABA). We used an array of methods of defining medication exposure including three conventional methods (ever statin exposure, cumulative duration of use, and cumulative dose) and two novel methods (recency-weighted cumulative duration of use and recency-weighted cumulative dose). To assess residual confounding, a negative control exposure was used to test the validity of our results. All exposure variables were time-dependent. Results: The population-based cohort of COPD had 39,879 patients with mean age of 70.6 (SD: 11.2) years and, of which, 53.5% were female. There were 12,469 patients who received at least one statin prescription. Results from the reference case multivariable analysis indicated a reduced risk from statin exposure (HR: 0.85 (95% CI: 0.73–1.00) in COPD patients, but this result not statistically significant. Using the two recency-weighted modelling approaches, statin exposure was associated with a statistically significant reduction in lung cancer risk (recency-weighted cumulative dose, HR: 0.85 (95% CI: 0.77–0.93) and recency-weighted cumulative duration of use, HR: 0.97 (95% CI: 0.96–0.99). Multivariable analysis incorporating the negative control exposure was not statistically significant (HR: 0.89 (95% CI: 0.75–1.10). Conclusions: The results of this population-based analysis indicate that statin use in COPD patients may reduce the risk of lung cancer. While the effect was not statistically significantly across all exposure definitions, the overall results support the hypothesis that COPD patients might benefit from statin therapy.
