This thesis proposes turning a Toronto subway station into a gallery that will display temporary exhibitions of contemporary art. Islington subway station, on the corner of Bloor Street West and Islington Avenue, will anchor a future civic and cultural centre and will become the social and public focal point of Etobicoke Centre. The building will turn this neighbourhood into a vibrant community, creating a self-sustaining node around which people will live, work, and play. This proposal has been inspired by urban sociologist Ray Oldenburg’s concept of the ‘third place’. In contrast to the first and second places of home and work, the third place encompasses the social realm, being a neutral space where people can gather and interact. The proposal for the Islington Gallery of Art also adapts new urbanist Peter Calthorpe’s theory of the ‘Transit Oriented Development’ where the subway station is the central node in the neighbourhood. Both of these concepts will be discussed further in the thesis. The Islington Gallery of Art will bring commuters a direct connection with culture. This gallery will transform the public space of infrastructure into a setting for informal public life. A third place will be created where one currently does not exist. The thesis combines the three narratives of public space, public transportation, and civic culture in the design of a mixed-use building. It explores how transportation infrastructure and architecture can combine with contemporary art to instigate the development for a new kind of place, one that isn’t a traditional street or square, near the periphery of the City of Toronto.

Ever-increasing interest in millimeter-wave and terahertz spectrum has prompted research and development of novel passive components working at these frequencies. Compared with the conventional planar components, non-planar dielectric devices become more attractive as frequencies increase due to their higher quality factors and dimensional tolerances. In this thesis, we present fast methods to analyze the millimeter-wave dielectric resonator and rod antenna. First, an analytical method has been developed to evaluate resonant frequencies, quality factors of the Whispering Gallery Mode (WGM) disk resonators and also the resonator-waveguide coupling. A numerical solver based on full-wave finite element method is implemented to verify the analytical result. This analytical model provides a solution for fast design and optimization of WGM resonators in filter and sensor applications. Secondly, a fast analytical approach based on local mode theory is introduced to calculate the radiation from tapered dielectric rod antenna. This efficient approximate model consumes much less computing resources and time, and demonstrates good agreements with full-wave numerical results. It supplies a quantitative way to understand the radiation mechanism and interaction between different parts of the antenna. Based on this, design criteria for the taper profile of rod antennas are given.

In the nineteen nineties, former Yugoslavia, went through a series of interstitial disputes, both religious and political, which evolved into hatred amongst its own people and ultimately into an unforgiving civil war. Rising demonstrations of the groups with different religious and cultural views within the country’s boundaries amalgamated into a war which divided the state into separate countries and left many cities and villages in despair, economic desolation and poverty. Although some have been directly affected by the physical casualties of war, others have suffered indirectly. One of the villages affected is Ruski Kerestur, found in the Republic of Serbia where more than ninety percent of the residents are non-Serbian. Many of its people fled the country due to political and economic uncertainties. This minority group is of the Carpatho-Rusyn decent which are the heart and soul of the village. Inspired by personal motive and desire to heal communities in distress, this thesis presents an opportunity to reconcile Carpatho-Rusyn people from the social diaspora in attempt to reclaim their national identity and give them the courage to persist on and continue the cultural legacy that has been nurtured for generations. Leaning on the speculation that ‘a spirit in people and belief in the future comes from the very foundation of a building’; it utilizes an architectural intervention as basis to conceive a quintessential communal space that redefines social and practical functions necessary for cultivating Rusyn traditions, ethics and domestic values. To develop an understanding of their public realm, the thesis dips into the crevices of time searching for Carpatho-Rusyn progress of development and migratory movement from their homeland in the Carpathian Mountains to the present day conditions. It tends to explore the idea of ‘adaptation’, the ideology that defines an architectural type through the process of transformation and negotiation of a community and its direct effect on public space, urban system and architectonic form. These theories will become a kernel for producing a useful and meaningful civic landmark that will strengthen the spirit of people giving hope and new life to the wounded village. The new ‘living monument’, Carpatho-Rusyn Art Gallery and Reconciliation Centre, presents a new gateway for Ruski Kerestur and its people into the healthy future shedding light on their moral values which were tamed for centuries by wars, ethnic cleansing and inexorable conviction of their non existence. The design proposal reintroduces a Rusyn way to the world and echoes the emotion of pride which permeates every Rusyn soul.

The technique of single particle Total Internal Reflection Microscopy (TIRM) has been used to study the scattering intensity from levitated microspheres. TIRM can be used to monitor the separation between microscopic spheres immersed in liquid (water in our case) and a surface with nm resolution. In the technique, microspheres scatter light when the evanescent waves are incident upon them. The intensity of the scattered light is directly related to the height above the surface and allows determination of the height. From the separation distance histograms, the interaction between the microsphere and interface may be characterized with a force resolution in the range of 0.01 picoNewtons. Such a system can be applied to the measurement of biomolecular interactions biomolecules attached to the microsphere and the surface. The intensity and scattering pattern of this light has been modeled using a modified Mie theory which accounts for the evanescent nature of the incident light. Diffusing Colloidal Probe Microscopy (DCPM) is an extension of the TIRM technique that simultaneously monitors multiple microsphere probes. The use of multiple probes introduces the issue of probe polydispersity. When measured at the surface, a variation in scattered light intensity of nearly one order of magnitude has been observed from a purchased microsphere sample. Thus the polydisperse collection of microspheres adds significant complexity to the scattered light signal. It is hypothesized that the dependence of the total scattered light intensity on microsphere size accounts for the scattered intensity distribution in a polydisperse microsphere sample. Understanding this variation in the scattered light with microsphere size will allow improved characterization of the microsphere/surface separation. Additionally, larger microspheres have the ability to resonantly confine light and produce spectrally narrow Whispering Gallery Modes (WGMs). It is hypothesized that WGMs may be excited in microspheres with the DCPM system. These modes may be used as a refractometric biosensor with high sensitivity to local refractive index changes on the surface of the microsphere. This research involves modeling scattered intensity distributions for polydispersed collections of microspheres based on modified Mie theory. The theoretical results are compared to experimentally obtained results and found to qualitatively explain the scattered light intensity distribution in a multiple probe DCPM system. This is an important result suggesting that microsphere size variation plays a major role in determining the distribution of scattered intensity in multiple microsphere probe systems. This work also suggests that it may be possible to excite such WGMs in a DCPM system. The introduction of WGMs would enable refractometric biosensing in such evanescent mode systems.

New methods of biological analyte sensing are needed for development of miniature biosensors that are highly sensitive and require minimal sample preparation. One novel technique employs optical resonances known as Whispering Gallery Modes (WGMs). These modes arise from total internal reflection of light at the internal surface of a high index microsphere within a low index medium and produce an evanescent field that extends into the surrounding medium. The WGMs produce multiple narrow spectral peaks that shift position with variations in the local index of refraction sampled by the evanescent tail of the WGMs. To excite these WGMs, we embed quantum dots (QDs) in the periphery of polystyrene microspheres to serve as local light sources. By coupling emission from the QDs to the WGMs, the sensors can be excited and interrogated remotely and, by monitoring the shift of multiple resonance modes, may provide higher sensitivity and accuracy compared with similar techniques. The high refractometric sensitivity of the WGMs offers potential for trace detection of molecules adsorbed onto or bound to the microsphere sensor elements. The sensitivity of these sensors is demonstrated by monitoring the wavelength shift of multiple resonant modes as bulk index of refraction is changed. The potential for targeted biosensing is explored through addition of a protein that adsorbs to the microsphere surface, thrombin. Microsensor response in all cases demonstrated increased sensitivity over theoretical predictions. Models based on Mie theory and continuity of the radial functions across the sphere-media interface were used to model the location, Q-factor, and sensitivity of the WGMs in microspheres by considering the embedded QDs as a high index outer layer. This model was used, along with estimates of the QD-layer index and penetration depth, to relate the locations and sensitivities of the modes to our experimental results with strong agreement between the two. In all, these microspheres demonstrate feasibility for use as remote microsensors with sensitivities rivaling current techniques.

This report is a case study of the presentation of craft at the Renwick Gallery, the craft museum of the Smithsonian American Art Museum (SAAM). The Renwick, founded in 1976, is a curatorial department of SAAM, focusing in modern and contemporary American craft. Through an examination of the museum’s galleries and exhibitions, interviews with staff, and an analysis of educational programming, this thesis explores how the Renwick defines craft implicitly and explicitly. Giving a context for this study is a history of the Renwick Gallery, as well as history of craft and its definitions. With these histories as background, the ways that the Renwick, and thus its visitors, understand craft is explored. The qualities specific to craft in the literature and manifest at the Renwick are examined in order to determine how they influence the presentation of craft at the Renwick. / text
