Specularity in Late Nineteenth-Century French Literature and Art
… Renoir and Cézanne. This thesis argues that specularity--a sort of mirror mimesis--was part of the fertile, artistic exchange between these representative writers and artists who shaped nineteenth century French literature and plastic arts during a period of turbulent social and political …

NUMERICAL ANALYSIS OF TURBULENT GAS-SOLID FLOWS IN A ROUGH HORIZONTAL CHANNEL USING THE EULERIAN TWO-FLUID MODEL
… of Johnson and Jackson (1987), which defined the specularity coefficient. The second study focuses specifically on the role of the specularity coefficient in characterizing wall roughness. The channel wall is rough from a particle perspective. The outcomes of the simulations were compared to the …

Spectroscopic surface scattering of confined acoustic phonons in silicon nanostructures
The specularity of phonons at rough crystal surfaces is a fundamental aspect of phonon transport in nanostructures. It directly impacts engineering problems such as heat conduction in nanostructures and dissipation in nanomechanical resonators. At room temperature, the available guidance from …

Radiative characteristics of spherical cavities having partially or completely specular walls
… is not very sensitive to the degree of specularity of the cavity wall. Also, there are situations in which the diffuse cavity is a more efficient emitter than a specular cavity. Absorption characteristic results show that for cavities having purely specular walls the absorption of …

The Role of Mirror Errors in Solar Energy Conversion
… perfect and have slope, shape, tracking, and non-specularity errors. This thesis investigates the role that these errors play in decreasing the overall efficiency with which radiation is converted to work in a system that relies on reflection. Three theoretical approaches are taken. Taking a …

High resolution millimeter wave imaging for self-driving cars
… and the absence of portions of the car due to specularity. This thesis presents HawkEye, a system that can enable high resolution mmWave imaging in self-driving cars. HawkEye addresses the above challenges by leveraging recent advances in deep learning known as Generative Adversarial Networks …

Post-environmentalism, the deep ecology/ecofeminist debate, and Surfacing : rereading environmental theory
… in the ways in which that logic is one of specularity, forwarded by a scientific privileging of ocular epistemology. I therefore use the strategy of 'Post-Environmentalism' in so far as it provides a way of making use of the historical and political importance of all the discourses …

Examining the taphonomic challenges to the 3D digitisation of fragmented bone
… the impact of surface properties such as colour, specularity, reflectance and shape on the quality of the recorded 3D image, but within the archaeological and palaeontological disciplines comparable work has not yet been developed. If archaeology and anthropology are to provide long term reliable …

Wireless Sensing with Machine Learning: Through-Wall Vision & Contactless Health Monitoring
… to address unique challenges due to the specularity of radio signals in the frequencies of interest, multipath reflections in indoor environments, high data rates and computation complexity, and the lack of training data and the difficulty in annotating radio signals. Our work addresses …

The effect of surface roughness on thermal and acoustic phonon transport in nanowires and nanomembranes
… limit of small correlation lengths. A surface specularity parameter based on Kirchhoff's approximation correctly predicts the observed frequency trend but underestimates the lifetimes by a constant multiplicative factor. This work paves the way toward designing higher quality thin films …
