The symbolism and self-imaging of Marcel Duchamp
"Revered as ""the father of modern art,"" Marcel Duchamp's idea inspired many new art forms after the 1960s including Neo-Dada, Op, Pop, Mobile Sculpture, Junk Art, Assemblage, Body Art, Happening, and Conceptual Art. Given his profound influence on contemporary and subsequent artists, Duchamp's …

Breathing Coloniality: An ethnographic case study of language and literacy ideologies and colonial power relations in the positioning and development of 1st generation black children's learning experiences in and outside school contexts
… and their effect on the positioning and self-imaging of people from non-mainstream populations. Data was collected through semi-structured interviews with parents and literacy instructors around observed practices and views on language use. In relation to language, my analysis revealed a …

Pulsed laser deposition of thick multilayer garnet crystal films for waveguide laser devices
… Other aims of the project were to fabricate a self-imaging waveguide amplifier and explore other applications of thick garnet crystal films such as the possibility of using a highly doped thick film as a thin-disk laser device. Now that the technique of thick garnet crystal film deposition via …

Discrete Wave Propagation In Quadratically Nonlinear Media
… In contrast to continuous systems, where Talbot self-imaging effect occurs irrespective of the pattern period, in discrete configurations this process is only possible for a specific set of periodicities. The major part of the dissertation is devoted to the investigation of soliton formation in …

Integrated microlenses and multimode interference devices for microflow cytometers
… device (MMI), which makes use of the self-imaging phenomenon in multimode waveguides, was also studied due to its less stringent fabrication tolerances. Optical components including channel waveguides, to route light on chip, were realised and integrated with microfluidic channels with …

Experimental studies of wave propagation in three-dimensional photonic crystals
… band gap approaches zero and becomes negative. Selfcollimation of the propagating beam and ultrarefraction, where radiation is redirected through large angles in the crystal, are predicted. Although not considered as the ideal structure, the face centered cubic (fcc) opaline photonic is crystal …

The pain of the pleasure of the text : Tournier, reading and sexuality.
… in the last chapter, I focus on Tournier's own self-imaging in terms of his quest for a double, in the form of his reader. More generally, illusion, instability and the imaginary can be seen as inhabiting the borders between textuality and sexuality: so, while this thesis looks at Tournier's …

High-average-power planar waveguide lasers
… 50µm Nd:GGG PLD waveguide. The effect of self-imaging was observed with a 27µm Nd:GGG PLD waveguide.

Interaction of Terahertz Radiation with Semiconductor Nanostructures and Quantum Systems
… this theory also predicts that a waveguide itself can be used to focus radiation, without any additional lenses or parabolic mirrors. I show that the waveguide can be understood as an interferometric system and that its output beam profile is a "two-dimensional interferogram" of the input …
