Deslanting the Lens
<p><em>Deslanting the Lens</em> examines the historical and sociological implications of how Asian men have been represented in popular American film. From the early days of “yellowface” to caricatures like Long Duck Dong, Asian men have been relegated to perpetual foreigner status in American …

Adding Personalized Wavefront Correction to a Scleral Lens After Lens Manufacture
PURPOSE: To date, wavefront-guided scleral lenses have relied on the full-surface method (FSM) of manufacture, which requires the wavefront correction to be integrated into the design of a traditional scleral lens prior to lens manufacture. A novel patch-cutting method (PCM) of manufacture would …

Embedded Power Active Contact Lens
… thesis designed and fabricated an active contact lens that notifies the user during the detection of an external wireless signal. The lens contained a printed antenna to communicate with a 2.4GHz system and provide inductive charging operating at 13.56 MHz. The lens utilizes a CBC005 5µAh thin film …

A metabolic lens on phytoplankton physiology
Phytoplankton are communities of diverse groups of prokaryotic and eukaryotic single-celled organisms responsible for nearly 50% of global primary production. The relative abundance of individual groups changes dynamically in response to environmental perturbations. Recent studies suggest that such …

Biochemical markers and contact lens wear
… a reliable selection procedure to match contact lens materials with individual wearers by the identification of a biochemical marker for assessment of in-eye performance of contact lenses. There is a need for such a procedure as one of the main reasons for contact lens wearers ceasing wearing …

Regression under a modern optimization lens
In the last twenty-five years (1990-2014), algorithmic advances in integer optimization combined with hardware improvements have resulted in an astonishing 200 billion factor speedup in solving mixed integer optimization (MIO) problems. The common mindset of MIO as theoretically elegant but …

Computational geometry through the information lens
This thesis revisits classic problems in computational geometry from the modern algorithmic perspective of exploiting the bounded precision of the input. In one dimension, this viewpoint has taken over as the standard model of computation, and has led to a powerful suite of techniques that …

Photographic lens manufacturing and production technologies
… for the manufacture of photographic objective lenses. Production of photographic lenses requires incredible precision in the melting, mixing, molding and machining of optical glass. Manual inspection methods are required to ensure optimum quality and to avoid inclusion of defects in glass. …

Learning Through the Lens of Robustness
Despite their impressive performance on large-scale benchmarks, machine learning sys- tems turn out to be quite brittle outside of the exact setting in which they were developed. How can we build ML models that are robust and reliable enough for real-world deployment? To answer this question, we …

Lens calcium homeostasis and selenite cataract
… calpain with subsequent proteolysis within the lens nucleus. This study was undertaken to investigate the biochemical mechanisms that lead to calcium accumulation in these circumstances. The components responsible for rat lens calcium regulation were defined by using either lens membrane vesicle …

The Extragalactic Lens VLBI Imaging Survey (ELVIS) : investigating galaxy cores and black holes with gravitational lens central images
This thesis describes the Extragalactic Lens VLBI Imaging Survey (ELVIS), a search for central images in gravitational lenses. We present the first four ELVIS targets, for which we have radio VLBI observations with resolutions of a few milli-arcseconds and sensitivities of 15 - 38 Jy. For PMN …
