description: L’héritage colonial et la mondialisation interrogent les sociétés océaniennes contemporaines sur leur relation au passé. Dans les récits de fiction océaniens la représentation de l’histoire occupe ainsi une place importante. La place de l’histoire dans la fiction pose tout d’abord le problème de la relation des hommes au passé et engage le rapport entre histoire et mémoire. Elle implique également la conception du temps et de l’espace, et en particulier l’originalité de l’approche océanienne de ces concepts. Mais les récits océaniens travaillent le concept même d’histoire en interrogeant les modalités de l’action humaine et en configurant une expérience originale de l’espace-temps.Les récits de fiction figurent ainsi une historicité originale qui rend l’initiative au sujet océanien et lui permet de s’approprier les apports exogènes sans renoncer à son éthique et son identité particulières, héritées de ses ancêtres et sans cesse réactualisées en fonction de circonstances changeantes.

description: Background: In order to maximize later health, there are established components and guidelines for quality follow-up care of breast cancer survivors. However, adherence to quality follow-up in Canada may not be optimal, and may vary by province. We determined and compared the proportion of patients in each province who received adherent and non-adherent surveillance for recurrence, new cancers and late effects, recommended preventive care, and recommended physician visits for comorbidities. Methods: Cohorts consisted of all adult women diagnosed with incident invasive breast cancer between 2007 and 2010/2012 in four Canadian provinces (British Columbia (BC) N = 9338; Manitoba N = 2688; Ontario N = 23,700; Nova Scotia (NS) N = 2735), identified from provincial cancer registries, alive and cancer-free at 30 months post-diagnosis. Their healthcare utilization was determined from one to 5 years post-treatment, using linked administrative databases. Adherence, underuse, and overuse of recommended services were evaluated yearly and compared using descriptive statistics. Results: In all provinces and follow-up years, the majority of survivors had more than the recommended number of visits to either an oncologist or primary care physician (range 53.8% NS Year 3; 85.8% Ontario Year 4). The proportion of patients with the guideline-recommended number of oncologist visits varied by province (range 29.8% BC Year 5; 74.8% Ontario Year 5), and the proportion of patients with less than the recommended number of specified breast cancer-related visits with either an oncologist or primary care physician ranged from 32.6% (Ontario Year 2) to 84.4% (NS Year 3). Underuse of surveillance breast imaging was identified in NS and BC. The proportion of patients receiving imaging for metastatic disease (not recommended in the guidelines) in BC, Manitoba, and Ontario (not reported in NS) ranged from 20.3% (BC Year 5) to 53.3% (Ontario Year 2). Compliance with recommended physician visits for patients with several chronic conditions was high in Ontario and NS. Preventive care was less than optimal in all provinces with available data. Conclusions: Quality of breast cancer survivor follow-up care varies among provinces. Results point to exploration of factors affecting differences, province-specific opportunities for care improvement, and the value of administrative datasets for health system assessment.

description: The main result is this The pagenumber of a series-parallel planar ordered set is at most two. We present an $O(n\sp3)$ algorithm to construct a two-page embedding in the case that it is a lattice, where n is the number of the elements of the lattice. Once consequence of independent interest, is a characterization of series-parallel planar ordered sets. A k-edge set $\{(a\sb{i}, b\sb{i}):1\le i\le k\},$ in an ordered set P, forms a k-twist in a linear extension L of P, if we have in ?? We give necessary and sufficient conditions for the existence of a linear extension L of an ordered set P such that k edges form a k-twist in L. We also, give lower and upper bounds in some classes of ordered sets. We proved that the problem to determine minimum number of pages required for a fixed linear extension of an ordered set is NP-complete. We conjecture that the pagenumber of planar ordered sets is unbounded. In contrast, we conjecture that the pagenumber of planar lattices is at most four.

Year: 2024

description: Recent studies have shown that precipitation hardening effectively enhances the mechanical quality factor of ferroelectric material. In this work, Li‐doped NaNbO₃, a material system with elliptical precipitates is investigated. We present a mechanical model to determine energetically stable precipitate shapes by minimizing the total energy, consisting of elastic and interface energy. Furthermore, we investigate the influence of external loads on the precipitate topology. Correct elastic constants as well as lattice misfits for the simulation are provided. The shapes determined from finite element simulations agree well with observed results.
Flaws and gaps in the women in computing literature

description: There are flaws and gaps in the current literature on women and computing. An analysis of Australian university enrolment data is used to compare Computing and Information Systems (IT) enrolments to the fields of Law and Medicine. There are flaws in the reasoning that the lack of role models and inhospitable nature of the IT field is an explanation for poor female enrolments. Gaps are evident in current published research as well as a lack of on-going statistical analysis of intervention programs. Questions are raised about the role the media plays in determining career choice perceptions in young females, particularly in relation to the status of computing careers.

Pulmonary vascular disease

description: Pulmonary vascular disease (PVD) and lung hypoplasia (LH) are the two main causes of mortality and morbidity in patients with congenital diaphragmatic hernia (CDH). Previous studies have shown that remodeling of the extracellular matrix (ECM) by elastase and matrix metalloproteinase (MMP) enzymes, concomitant with smooth muscle cell (SMC) proliferation and deposition of ECM proteins and growth factors, leads to primary pulmonary hypertension (PH) and that blockade of this pathway results in disease reversal. The aim of our study is to determine whether a similar pathway is induced in the PVD associated with CDH and to verify whether its inhibition will lead to reversal of PVD. Firstly, we confirmed various aspects of PVD in the nitrofen induced CDH rat model. These included: left lung hypoplasia, right ventricular hypertrophy, and increased arterial smooth muscle wall thickness alongside decreases in arterial lumen area and total number of distal pulmonary vessels. We also showed increases in elastase and matrix metalloproteinase (MMP) enzyme activities within distal pulmonary arteries (PAs), which, we were able to inhibit using serine elastase (sivelestat, elafin, and serpina1) and MMP (GM6001) inhibitors. Furthermore, we confirmed increased SMC proliferation and deposition of osteopontin (OPN) and epidermal growth factor (EGF) within the diseased vasculatures. We are now working on using sivelestat and GM6001 pharmaceuticals as well as endothelial progenitor cells (EPCs) and mesenchymal stem cells (MSCs) modified to express elafin and serpina1 to determine their abilities to reverse the PVD associated with CDH. This project is part of our translational research program with the ultimate goal of developing a novel strategy of targeting PVD in infants with CDH to improve patient survival and long-term outcome.

SPANC

description: Chemical transformations that join two molecular components together rapidly while remaining highly efficient and selective are valued for their elegant simplicity and effectiveness in a myriad of applications. By applying the principles of ‘click’ chemistry to biology, information about molecular interactions in vivo can therefore be gained from minimally perturbing bioorthogonal coupling reactions. Developing bioorthogonal ‘click’ reactions – reactions that do not cross-react with biological components – provides new ways to accurately study biological systems at the molecular level. This thesis describes the development of such tools. Strain-promoted alkyne-nitrone cycloadditions (SPANC) represent rapid, efficient, selective, and tunable conjugation strategies that are applicable to biomolecular labelling experiments. Herein, SPANC reactions with bicyclo[6.1.0]nonyne are examined using physical organic methods to determine the stereoelectronic factors governing SPANC reactivity. Second-order rate constants (k2) of up to 1.49 M-1s-1 were measured and the resulting cycloadditions are applied to the design and synthesis of nitrone-based molecular probes. The first example of SPANC-mediated metabolic labelling in live-cell bacteria is reported, establishing SPANC as an efficient and bioorthogonal metabolic labelling strategy for cellular labelling.
Frequency and significance of HIV-1 infection of CD8+ T-cells: Implications for viral pathogenesis

Subjects: subject: Biology, Virology.

description: To date, the effect of HIV-1 infection on CD8+ T-cells remains poorly studied. Previous studies have shown that the effector functions of CD8+ T-cells diminish during AIDS. We postulated that CD8+ T-cell functions decrease due to the tropism of HIV-1 for CD8+ T-cells. Therefore we examined whether CD8+ T-cells provide suitable targets for HIV-1 infection and the mechanism(s) by which the virus enters the cells. We hypothesized that HIV-1 entry into these cells may be facilitated through access to extracellular receptors. Ex vivo experiments were performed using blood samples from a cohort of HIV-1 infected patients attending the Ottawa Hospital Immunodeficiency Clinic. Frequency of HIV-1 infection was monitored by flow cytometric detection of HIV-1 p24 antigen and viral production from separated CD8+ and CD4+ T-cell lineages was assayed by the quantitation of viral RNA transcripts. Primary CD8+ T-cells and CD8+ T-cell clones used in the in vitro studies were isolated from the peripheral blood of healthy volunteers. HIV-1 infection was monitored by both ELISA and flow cytometric analyses. Similarly, receptor analysis was performed by flow cytometry and confirmed by RT-PCR analysis. There was a significantly higher frequency of CD8+HIV+ cells than CD4+HIV+ cells found in the ex vivo studies of patient samples, however, viral production from the CD8+HIV+ subset was 2-3 logs lower than that found in CD4+HIV+ T-cells. In addition, CD8+ T-cells served as suitable targets for productive HIV-1 infection in vitro and preferential HIV-1 replication occurred in the memory T-cell subset. Interestingly, the HTLV-I transformed CD8+ T-cell clones exhibited HIV-1 production 20-fold greater than CD4+ T-cells. Our research also demonstrated that during the course of infection, there was a decrease in mean expression of the CD8 and CXCR4 cell-surface molecules in the HIV-1 infected CD8+ T-cell clones. Accordingly, the use of antibodies to the CD8 or CXCR4 molecules eradicated viral adsorption and replication in the CD8+ T-cell clones. Our research was the first to demonstrate the significance and susceptibility of CD8+ T-cells to HIV-1 infection through both ex vivo and in vitro analyses. We conclude, with multiple lines of evidence detecting and measuring HIV-1 infection of CD8+ T-lymphocytes, that this cellular target and reservoir may be central to HIV-1 pathogenesis. By identifying a novel target of HIV-1 and potential cellular receptors used by the virus, future therapeutic strategies may be designed to help prevent and treat HIV-1 infection.
Absolute quality-of-service differentiation in optical burst switching networks

Subjects: subject: Engineering, Electronics and Electrical.

description: Absolute Quality of Service (QoS) differentiation is an important issue in Optical Burst Switching (OBS) networks. This thesis aims at providing loss rate guarantees for the priority-guaranteed (PG) classes on an end-to-end (E2E) basis while keeping the loss rate of the best effort (BE) class traffic as low as possible. We first present a per-hop absolute QoS differentiation scheme called Reserve-and-Preempt Scheme (RPS). The Analytical model of RPS is provided as well. In order to support networks with multiple PG classes, RPS is extended into a variety of new schemes. Among the proposed schemes, Extended Reserve-and-Preempt Scheme (ERPS) is easier to implement and provides the best performance. On an E2E basis, we apply ERPS over an entire OBS network. To achieve a balance between scalability and unnecessary bandwidth consumption on the intermediate links, we propose optimized priority grouping with single-class constraint (OPT-SC) and optimized priority grouping without single-class constraint (OPT-NC). Furthermore, to cope with the traffic-fluctuation and the load-unbalance problems in OBS networks, we present a novel self-adaptive algorithm, which integrates two priority-level adjustment mechanisms, priority-level upgrading (PLU) and priority-level degrading (PLD). Extensive simulations are conducted to demonstrate the effectiveness of the proposed schemes. Simulation results show that our proposed RPS scheme outperforms the existing schemes. The correctness of the analytical model of RPS is demonstrated by simulation. We also observe that ERPS performs the best among the schemes extended from RPS. Simulation results also demonstrate that the proposed OPG-SC and OPG-NC techniques can reduce the bandwidth consumed by the PG classes and improve the performance of the BE class. Finally, we observe that the proposed self-adaptive algorithm can improve the performance of the PG classes with minimum expense on the BE class. At the same time, it is shown to be self-adaptive to traffic fluctuation.

Subjects: subject: Chemistry, Inorganic.

description: This work is concerned with the preparation and examination of guanidinate complexes. One method of synthesis of such ligands, as presented in Chapter 2, is the insertion of carbodiimide into a metal-amido group. The direct reactions of $\rm M(NMe\sb2)\sb5$ with either dicyclohexylcarbodiimide (CyN=C=NCy) or diisopropylcarbodiimide $\rm(\sp{i}PrN{=}C{=}N\sp{i}Pr)$ proceeded smoothly at room temperature under nitrogen to yield $\rm\lbrack RNC(NMe\sb2)NR\rbrack M(NMe\sb2)\sb4$ (M = Ta, Nb; R = Cy, $\rm\sp{i}Pr).$ The spectroscopic characterization of these materials is consistent with a symmetrical chelating bidentate guanidinate anion bonded to a pseudo-octahedral metal center. In chapter 3, we prepared $\rm N,N\sp\prime,N\sp{\prime\prime}$-tricyclohexylguanidine and triisopropylguanidine. With this guanidine ligand, we focus on the elimination of amido ligands from homoleptic Ta(V) and Nb(V) dimethylamido complexes. The complex $\rm TaCl(NMe\sb2)\sb3\{\lbrack CH\sb3)\sb2CHN\rbrack\sb2CN(H)CH(CH\sb3)\sb2\}$ was also isolated and crystallographically characterized. In Chapter 4, the direct reaction of Ta and Nb alkyl complexes $\rm M(Me)\sb{x}Cl\sb{y}$ (M = Ta, x = 3, y = 2; M = Nb, x = 2, y = 3) with $\rm N,N\sp\prime,N\sp{\prime\prime}$-tricyclohexylguanidine and $\rm N,N\sp\prime,N\sp{\prime\prime}$-triisopropylguanidine was investigated. The preliminary results of efforts to get a second alkyl elimination are also reported. (Abstract shortened by UMI.)

description: Compositionally complex transitional metal nitrides are possible candidates for ultra‐high temperature usage and are known for their superior properties due to the high configuration entropy. It is often difficult to synthesize pure metal nitrides in bulk, due to significant oxygen contamination; hence, they are synthesized mainly as thin films through magnetron sputtering, chemical vapor deposition or surface nitridation of high entropy alloys. The present article reports on a single‐phase compositionally complex ceramic, i.e., (Ti₀.₂Zr₀.₂Hf₀.₂Nb₀.₂Ta₀.₂)NₓC₁₋ₓ, that is synthesized for the first time by employing an organometallic precursor route and using a double ammonolysis process. A multidisciplinary approach is performed to study these compositionally complex nitride and carbonitride systems, including experimental and theoretical investigations.

description: For machine manufacturing companies, besides the production of high quality and reliable machines, requirements have emerged to maintain machine-related aspects through digital services. The development of such services in the field of the Industrial Internet of Things (IIoT) is dealing with solutions such as effective condition monitoring and predictive maintenance. However, appropriate data sources are needed on which digital services can be technically based. As many powerful and cheap sensors have been introduced over the last years, their integration into complex machines is promising for developing digital services for various scenarios. It is apparent that for components handling recorded data of these sensors they must usually deal with large amounts of data. In particular, the labeling of raw sensor data must be furthered by a technical solution. To deal with these data handling challenges in a generic way, a sensor processing pipeline (SPP) was developed, which provides effective methods to capture, process, store, and visualize raw sensor data based on a processing chain. Based on the example of a machine manufacturing company, the SPP approach is presented in this work. For the company involved, the approach has revealed promising results.

description: The call centre industry relies upon technology; the conventional speech telephone, to serve customers. Call centres do not exist for the customer to physically interact with, apart from via the telephone, and are in effect virtual organizations. Hence, the criteria used to assess the service is different from a face-to-face service encounter. Whilst call centres have benefited customers, by increasing the time period that services are available, there is also evidence that it has frustrated them. This research aims to explore the contribution technology has made to service improvement in this emerging virtual servicescape.

description: Endometrial regenerative cells (ERCs) are a new type of mesenchymal-like stromal cells, and their therapeutic potential has been tested in a variety of disease models. SDF-1/CXCR4 axis plays a chemotaxis role in stem/stromal cell migration. The aim of the present study was to investigate the role of SDF-1/CXCR4 axis in the immunomodulation of ERCs on the experimental colitis. The immunomodulation of ERCs in the presence or absence of pretreatment of SDF-1 or AMD3100 was examined in both in vitro cell culture system and dextran sulphate sodium-induced colitis in mice. The results showed that SDF-1 increased the expression of CXCR4 on the surface of ERCs. As compared with normal ERCs, the SDF-1-treated, CXCR4 high-expressing ERCs more significantly suppressed dendritic cell population as well as stimulated both type 2 macrophages and regulatory T cells in vitro and in vivo. Meanwhile, SDF-1-pretreated ERCs increased the generation of anti-inflammatory factors (e.g., IL-4, IL-10) and decreased the pro-inflammatory factors (e.g., IL-6, TNF-α). In addition, SDF-1-pretreated CM-Dil-labeled ERCs were found to engraft to injured colon. Our results may suggest that an SDF-1-induced high level of CXCR4 expression enhances the immunomodulation of ERCs in alleviating experimental colitis in mice.

description: Autonomic reflex ascertains cardiovascular homeostasis during standing. Impaired autonomic reflex could lead to dizziness and falls while standing; this is prevalent in stroke survivors. Pulse rate variability (PRV) has been utilized in the literature in lieu of heart rate variability (HRV) for ambulatory and portable monitoring of autonomic reflex predominantly in young, healthy individuals. Here, we compared the PRV with gold standard HRV for monitoring autonomic reflex in ischemic stroke survivors. Continuous blood pressure and electrocardiography were acquired from ischemic stroke survivors (64 ± 1 years) and age-matched controls (65 ± 2 years) during a 10-minute sit-to-stand test. Beat-by-beat heart period (represented by RR and peak-to-peak (PP) intervals), systolic blood pressure (SBP), diastolic blood pressure (DBP), and pulse arrival time (PAT), an indicator of arterial stiffness, were derived. Time and frequency domain HRV (from RR intervals) and PRV (from PP intervals) metrics were extracted. PAT was lower (248 ± 7 ms vs. 270 ± 8 ms, p < 0.05) suggesting higher arterial stiffness in stroke survivors compared to controls during standing. Further, compared to controls, the agreement between HRV and PRV was impaired in stroke survivors while standing. The study outcomes suggest that caution should be exercised when considering PRV as a surrogate of HRV for monitoring autonomic cardiovascular control while standing in stroke survivors.

description: The Carex nardina complex is a group of one to three species (C. nardina, C. hepburnii, C. stantonensis) and six taxa of unispicate sedges (Cyperaceae), the taxonomy of which has been controversial since the 1800s. As initial DNA phylogenies suggested that the complex was nested within Carex section Filifoliae and sister to C. elynoides, a species often confused with C. nardina and sympatric with it in the western North American Cordillera, analyses were conducted to determine whether C. hepburnii, C. stantonensis and other infraspecific taxa could be the result of hybridization. Morphometric and molecular analyses found no substantial evidence for hybridization and supported the recognition of no taxon beyond C. nardina. Consequently, this study concludes that the complex comprises a single variable species, Carex nardina, distributed throughout arctic North America south through the western Cordillera to New Mexico with a minor portion of its range in northeastern Russia, northwestern Scandinavia and Iceland.

description: We measure the large-scale real-space power spectrum P(k) using luminous red galaxies (LRGs) in the Sloan Digital Sky Survey (SDSS) and use this measurement to sharpen constraints on cosmological parameters from the Wilkinson Microwave Anisotropy Probe (WMAP). We employ a matrix-based power spectrum estimation method using Pseudo-Karhunen-Loève eigenmodes, producing uncorrelated minimum-variance measurements in 20 k-bands of both the clustering power and its anisotropy due to redshift-space distortions, with narrow and well-behaved window functions in the range 0.01h/Mpc0.1h/Mpc and associated nonlinear complications, yet agree well with more aggressive published analyses where nonlinear modeling is crucial.

description: Despite recognized geographic and sex-based differences in hemoglobin in the general population, these factors are typically ignored in patients with chronic kidney disease (CKD) in whom a single therapeutic range for hemoglobin is recommended. We sought to compare the distribution of hemoglobin across international nondialysis CKD populations and evaluate predictors of hemoglobin.
La persistance des chocs dans une perspective désagrégée : le cas du Canada, 1870-1996.
Creators: name: Hamdad, Malika.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1999
Subjects: subject: History, Canadian.

description: Le propos de cette thèse est d'examiner la persistance des chocs dans une perspective désagrégée. Cette approche permet de décomposer la persistance des chocs sur la production agrégée et sectorielle en deux composantes: la première due à des chocs d'origine macroéconomique explicitement identifiés et la seconde à des chocs "autres," probablement d'origine sectorielle. Ce cadre d'analyse a été appliqué à des séries historiques inédites sur la production sectorielle en prix constants de l'économie canadienne pour les périodes d'avant-guerre et d'après-guerre, dont les chocs macroéconomiques explicitement identifiés sont, respectivement, le choc du blé et le choc pétrolier. Les résultats auxquels cette thèse a abouti ont (1) confirmé dans le contexte canadien que l'approche désagrégée fournit des estimés plus fiables de la mesure de la persistance que ceux obtenus au moyen d'une approche agrégée; (2) permis de montrer que les effets des chocs ont eu tendance à devenir légèrement plus persistants à travers le temps; (3) mesuré le degré auquel le choc du blé a contribué à provoquer une déviation permanente sur la production de l'économie et ainsi corroborer la thèse traditionaliste du développement historique du Canada.
Transformational leadership and generativity: A narrative exploration
Creators: name: Bell, Christina
Publisher: name: Swinburne
Year: 2024

description: This qualitative study explored the narrative themes that emerged in the life stories of 12 senior executives identified as high in transformational leadership. The research examined how participants’ life stories contributed to their sense of identity and to their adoption of a transformational leadership style. On the basis of an apparent conceptual relationship between the psychosocial construct of generativity and behaviours associated with transformational leadership, generative themes were expected to emerge in the life narratives. The analysis was exploratory and verificationary. General themes – struggle, external resources and support and inner strength - reflecting a strongly redemptive sequence were identified as well as five of the themes previously identified in the life stories of generative adults (McAdams, 2006). The findings suggest that transformational leaders’ generative concerns are forged by their life narratives located in the private world of their identities and beliefs, and manifested in transformational leadership behaviours in the public world of the organisations they lead. Implications of findings and directions for future research on generativity and transformational leadership are discussed.
Nietzsche and the problem of morality.
Creators: name: Cameron, Frank.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2001
Subjects: subject: Philosophy.

description: This doctoral dissertation is a study of Nietzsche's views on morality in order to assess his contribution to moral philosophy. Towards this end, it examines Nietzsche's understanding of morality as well as the scope of his attack. I then offer a reading of Nietzsche's critique of morality, arguing that he rejects morality insofar as it functions within society to preserve the 'herd' at the expense of 'higher types' whose flourishing resides elsewhere. In short, I claim that Nietzsche rejects morality insofar as it proves inimical to the flourishing of these 'higher types'. I also claim that Nietzsche is more than a mere critic of morality, and that his fundamental 'ethical' preoccupation with exemplary individuals is what motives his critique, and forms the basis of his affirmative ethic of human flourishing. Moreover, I contend that Nietzsche defends his positive morality by presenting the character of Zarathustra (Thus Spoke Zarathustra), and later himself (Ecce Homo) as exemplars of human excellence who must rely on their ability to convince others performatively, rather than by means of discourse, or argumentation. Ultimately, I conclude that Nietzsche's ethics does not fit comfortably within the moral tradition as he is an opponent of deontological ethics, utilitarianism, and virtue ethics despite certain affinities with the latter. This fact does not detract from the rich contribution that Nietzsche makes to moral philosophy as bode critic and champion of an affirmative ethic.

Living Pedagogies of a Game-Master: An Autoethnographic Education of Liminal Moments
Creators: name: Lachance, Graeme

description: This study presents the concept of the pedagogy of the game-master. Written from a bricolage of autoethnographic perspectives, a fractured narrative was (de)composed out of the author’s dual experiences as educator and game-master of fantasy tabletop-role-playing games. The narrative seeks to evoke the blurred boundaries of what it means to occupy each role, dwelling between fantasies, (teaching) realities, and player/person/persona identities (Waskul & Lust, 2004), constructing and remaining in the middle of a bridged pedagogy which spans education and tabletop role-playing. From the narrative, the latter section of this manuscript presents a discussion of how the liminal duties of the game-master might help draw educators to and beyond the boundaries of what is possible in education.

Hybrid electro-optical switch

description: Rapid changes in population distribution across Canada and the introduction of new telecommunication services to the consumer market have resulted in a number of significant challenges for existing network infrastructure. Fast growing populations in metropolitan regions require high density access networks to meet the growing need for bandwidth that results. Furthermore, new services such as high definition TV, online gaming and real-time video teleconferencing are becoming increasingly popular among consumers. These services require higher bandwidth to be available to end users. Changes in the Canadian economy will soon lead to a transition in Canadian industry from manufacturing to services and exploration of natural resources. This will create opportunities for new industrial development and growth in northern regions. Expanding industrialization towards northern Canada will require deployment of reliable telecommunication infrastructure. The combination of open source software, Linux operating system and Personal Computer (PC) based hardware platform is proposed to become the foundation for low cost and flexible technology that will provide transition towards all-optical infrastructures. An innovative prototype of a low-cost optical gigabit Ethernet switch is presented and its benchmark results are discussed. Scalability of the switch and its future applications in optical networks are studied. A prototype of a software based data encapsulation system was designed and implemented in a PC based platform, and its performance was evaluated using real data that was captured in commercial LAN. Semiconductor optical amplifiers (SOA) are studied as a building block in next generation switching devices for all-optical access networks. A prototype of an SOA-based low-cost optical switching device with implemented FPGA based controlling mechanism is presented and its characteristics are discussed. SOA is also studied as an energy efficient optical amplifier that can be deployed in end user facilities. The presented results provide proof of concept of a low cost flexible platform that can be used to design and build network devices to facilitate the transition of existing telecommunication networks towards next generation optical access infrastructure.
