A new woman's venture: linking a little magazine to the suffrage atelier
The Venture: An Annual of Art and Literature, a little magazine edited by Somerset Maugham and Laurence Housman, was published in 1903 by John Baillie in London and in 1905 by The Arden Press in Leamington. The magazine made its debut at a time when new sociopolitical ideas of femininity began to pervade literature and public discourse. Although its co-editors were both men, Maugham was a supporter of women’s suffrage and Housman was notable for his activism, acting as a central figure in the Men’s League for Women’s Suffrage established in 1907.
The Venture presented Maugham and Housman with the opportunity to use their authority as editors to participate in broader social and political affairs. Expressed throughout the magazine is a special attention to feminism; the literary and art contents examine the varying experiences of modern women in Victorian society, and as a whole, the magazine works to promote and celebrate the achievements of New Women. The curation of feminist work in The Venture is unlikely a coincidence, and it would be a mistake to dismiss it as such. This analysis aims to demonstrate that Maugham and Housman edited The Venture with a primarily feminist agenda in order to promote women’s suffrage, and inspire curiosity, individuality, and activism in Victorian women., Fraschetti, E.

Bio Modelling For Comfort Aircraft Chair Design
The work presented in this report is to help develop and complete the methodology that can quickly
predict the pressure distribution and estimate the comfortability of the aircraft seat. For this thesis, the
human back and spine are introduced and modelled as the focus is only on the backrest of the aircraft seat.
The bio modelling of the back and spine consists of the geometry including the spine curvature and back
shape at various conditions. The variables include the body type of the sitter, the sitting posture and the
backrest recline angle. Multiple cases of the body condition combining the these mentioned variables were
modelled, which generates a comparatively inclusive human model for the future work of pressure
distribution analysis. The initial building of the spine curve is based on an existing spine data, and the back
shape is captured by experiments using 3D scanning technology. Forces acting on the spine are also
obtained as a part of the modelling.
With this more complete the inclusive bio model of the body, the pattern of the contact and pressure
can then determine a more efficient configuration of cushion or aircraft seat innovation and design to
achieve a better comfort.
Brothers in the kitchen: the uprising, exodus and survival of a Tamily minority
Brothers In the Kitchen (BiTk), is a site-specific live-documentary performed with an audience inside a fully operational restaurant. The triumvirate of story, performance, and audience is used to create an interactive and immersive documentary experience incorporating oral storytelling, poetry, dance, music, archival materials and television— all performed live. BiTk is the story of the uprising, exodus and survival of Tamil Sri Lankan citizens who fled a brutal civil war and sought refuge in Canada. The ethnic conflict, between the Buddhist Sinhala majority and the Hindu Tamil minority, sparked a mass exodus following the deadly riots of Black July in 1983. Subsequently, a staggering 300,000 Tamils found asylum in Canada. Soon an inordinate number of them began work as cooks and dishwashers in many Canadian restaurants. This live documentary is performed thirty years after the arrival of the first boatload of Tamil refugees, found adrift off the coast of Newfoundland, in 1986.
Closing Canada's digital divide: a review of policies in Canada and abroad
This paper explores Canada’s telecommunications policy landscape, with an aim of evaluating its effect on Canada’s digital divide. It looks into decisions made by the CRTC and ISED (and its predecessors), which have influenced the development of broadband infrastructure in Canada.
This paper also evaluates the efficacy of digital literacy training programs, aimed at allowing Canadians to leverage connectivity. Finally, it concludes with a discussion about how the Innovation Agenda can be used as a mechanism to narrow Canada’s digital divide.
Computed tomography airway tree tortuosity features predict functional small airway disease in chronic obstructive pulmonary disease
Over 1 000 000 Canadians are diagnosed with Chronic Obstructive
Pulmonary Disease (COPD) and by 2020 the disease will be the third
deadliest on Earth.
Despite high prevalence, diagnosis of COPD occurs late in the
disease course, after a large portion of the small airways are destroyed.
Current methods to quantify small airway disease (SAD) using the
Disease Probability Measure (DPM) approach requires CT images
acquired at full inspiration and full expiration, and therefore there are
technical challenges and dose concerns
Computed Tomography (CT) imaging using only a single full
inspiration CT image can be used segment the central airway tree and
generate quantitative morphometric measurements., Genkin, D., Aslam, D., Bartlett, J., Coxson, H., Tan, Wan C., Hogg,...Kirby, M.

Design And Aerodynamic Analysis Of Compliant Mechanism Based Morphing Wings
Aircraft today use discrete control surface, typically mounted using pin and sliding joints. These designs can lead to high part-count assemblies and backlash within the assemblies that require lubrication and frequent maintenance. These wing designs also feature fixed dimensions and do not allow for geometry changes mid-flight. These limitations lead to a compromised design that must work relatively well in all situations. This causes inefficiencies in all stages of flight.
The Wright brothers, who achieved the first successful powered flight did not use these techniques. Instead they used a system on cables to apply tension and bend the wings to changes their angle of attack. They called this technique wing warping. As aviation advanced it quickly moved from the wing-warping technique towards the discrete element control surfaces. However, there is renewed interest in techniques such as wing warping as the idea of morphing wings becomes more prevalent in aerospace research. Morphing wings would allow for changing major characteristics, such as camber, span, sweep, etc. of the wing mid-flight and allow for continuous optimization through all stages of its mission.
The design covered in this thesis was centered around camber morphing of the wing in flight. Biomimicry played a large role in the design, with research into the skeletal systems of birds and fish used to dictate the rib structures. This bio-inspired path led to the use of compliant mechanisms for the ribs. This choice allowed for a low part-count and zero-backlash design that would require no maintenance and have a very long service life due to an extremely low amount of fatigue. Several design iterations were tested with different common desktop 3-D printing materials. The final rib design was made of PETG and whose compliant shape was directly inspired by the skeletal structure of the spine of a fish. The design proved to be extremely reliable and robust.
Skin design has long been one of the biggest hurdles of morphing wing design. Most research reviewed in this paper used an elastomer style skin that was pre-stretched to reduce buckling under compression. Through testing it was found that this method is difficult and unreliable to maintain a smooth and continuous surface. Even when pre-stretching, the elastomer would fatigue and buckle under compression. The final design was a PETG panel with a web and flange that would interact with the rib structure and was able to translate chordwise along the rib as the wing altered its camber. The skin had built-in flexures to reduce bending actuation forces. The wing also featured a rigid leading-edge skin panel with which the other skin panels would be able to slide under to maintain skin coverage under both extension and compression of the wing surfaces. This however led to aerodynamic problems that were discovered in the CFD analysis.
The wing was prepared for CFD using finite element analysis to produced morphed wing bodies for a 0, 10, 20, and 30-degree trailing edge deflection angles. A model was also produced of the same base airfoil (NACA 0018) with a hinged flap of 30% chord length deflected by the same amount to serve as a performance benchmark for the morphing wing. The main criteria used to evaluate the performance were the lift, drag, and lift-to-drag ratios. For the 0⁰ tests, the morphing wing had up to almost 29% higher drag at high speeds. The results showed that the 10⁰ deflection tests found up to a 115% increase in lift over the hinged flap design and a lift-to-drag ratio of up to 161% higher for the morphing wing. The 20⁰ and 30⁰ tests saw the lift advantage of the morphing wing decrease but on average across all tests, the morphing wing had a lift coefficient higher than the hinged flap by 43%. Additionally, for the large deflection tests the hinged flap had up to a 60.5% advantage in lift-to-drag ratio.
The computational fluid dynamic analysis showed that due to the larger effective angle of attack and the step-down in the skin of the morphing wing, at larger deflection angles the flow would separate much earlier along the chord. Therefore, based on the analysis, the morphing wing would create a substantial performance and efficiency gains when wing trailing edge deflection was kept below 20⁰. This meant it would be suitable for stages of flight such as takeoff and climb.
Planned future work aims to reduce the 0⁰ drag of the morphing wing as well as the early flow separation at high angles of deflection. It is assumed, that by scaling up the wing, the proportion of the step size will decrease dramatically and as a result would improve the flow characteristics. Additionally, the placement and rotational limits of the flexures can be tested further to optimize the morphed shape to reduce the severity of the adverse pressure gradient along the upper surface when in high deflection states. With continued work on improving the flow separation, this design proves promising for even high-deflection cases. Overall the V4 rib design and the accompanying compliant skin panel design were very successful for their initial tests.

Development of CT texture analysis in COPD and association with visual scoring and DLCO
• To determine if CT texture features, such as GLCM and FD, can differentiate patients with COPD from healthy volunteers, and are related to lung function
• To determine if CT texture features are association with qualitative visual scoring
• To determine if CT texture features are significantly associated with COPD outcomes, independent of qualitative scoring and standard quantitative CT emphysema measurements
• CT texture features can be developed to objectively aid in quantifying the severity of emphysema, and may provide information complementary to qualitative visual assessment, Lui, V., Tan, W.

Digital Processing with a Hybrid Plasmonic Logic Nanogate
We developed a simple strategy to gate a plasmonic event with a hybrid photoresponsive compound capable of mimicking AND-type logic behaviour. Binary digits are encoded into ultraviolet and visible illumination (which are used as inputs) and the fluorescence of the molecule (the arithmetic output). The plasmonic process chosen is the visible lightcontrolled, gold-nanoparticle (AuNP) catalysed reduction of resazurin to resorufin, while the second optical input is the UVA-induced cleavage of a 2- nitrobenzyl quencher. The synergistic combination of plasmonic nanostructures and organic molecules allows for the manipulation of a programmable Boolean logic operation at the molecular level., Al Nubani, L., Dogantzis, N., Hodgson, G., Impellizzeri, S.(2019, October).

Experimental data acquisition and analysis of an underground thermal storage medium
A ground source heat pump (GSHP) is a system that uses the ground as a heat source/sink to provide heating/cooling to a conditioned space. During the winter, a GSHP uses a heat pump cycle to move heat from the ground into a space in order to heat it In the summer, the space is cooled as heat is pumped out of the space and back into the ground GSHPs are a sustainable alternative to conventional HVAC systems because they do not rely on direct fossil fuel consumption, and they are highly efficient as they move heat rather than generate it In addition, the temperature of the ground remains constant throughout the year, resulting in a greater thermal efficiency, and therefore less energy consumption, Gonzalez-Ferras, A.
