Fabrication of waveguide spatial light modulators via femtosecond laser micromachining
(SPIE, the International Society of Optical Engineering, 2016-03)We have previously introduced an anisotropic leaky-mode modulator as a waveguide-based, acousto-optic solution for spatial light modulation in holographic video display systems. Waveguide fabrication for these and similar ... -
Fabrication Process Yielding Saturated Nanowire Single-Photon Detectors With 24-Picosecond Jitter
(Institute of Electrical and Electronics Engineers (IEEE), 2015-03)We present an optimized fabrication process for superconducting nanowire single-photon detectors that allowed us to obtain a yield of ~70% for detectors based on 80-nm-wide niobium nitride nanowires. We fabricated detectors ... -
Fabrication, characterization, and application of large-scale uniformly hybrid nanoparticle-enhanced Raman spectroscopy substrates
(MDPI AG, 2019-05-01)© 2019 by the authors. Surface-enhanced Raman spectroscopy (SERS) substrates with high sensitivity and reproducibility are highly desirable for high precision and even molecular-level detection applications. Here, large-scale ... -
Fabrication-Adaptive Optimization with an Application to Photonic Crystal Design
(Institute for Operations Research and the Management Sciences (INFORMS), 2014-04)It is often the case that the computed optimal solution of an optimization problem cannot be implemented directly, irrespective of data accuracy, because of either (i) technological limitations (such as physical tolerances ... -
Fabrics with tunable oleophobicity
(Wiley-VCH, 2009-03)A simple “dip-coating” process that imbues oleophobicity to various surfaces that inherently possess re-entrant texture, such as commercially available fabrics, is reported. These dip-coated fabric surfaces exhibit reversible, ... -
FabRobotics: Fusing 3D Printing with Mobile Robots to Advance Fabrication, Robotics, and Interaction
(ACM|Eighteenth International Conference on Tangible, Embedded, and Embodied Interaction, 2024-02-11)Modern vector processors support a wide variety of instructions for fixed-point digital signal processing. These instructions support a proliferation of rounding, saturating, and type conversion modes, and are often fused ... -
Face Gender Recognition in the Wild: An Extensive Performance Comparison of Deep-Learned, Hand-Crafted, and Fused Features with Deep and Traditional Models
(Multidisciplinary Digital Publishing Institute, 2020-12-24)Face gender recognition has many useful applications in human–robot interactions as it can improve the overall user experience. Support vector machines (SVM) and convolutional neural networks (CNNs) have been used ... -
Face Recognition Deficits in Autism Spectrum Disorders Are Both Domain Specific and Process Specific
(Public Library of Science, 2013-09)Although many studies have reported face identity recognition deficits in autism spectrum disorders (ASD), two fundamental question remains: 1) Is this deficit “process specific” for face memory in particular, or does it ... -
Face-selective electrostatic control of hydrothermal zinc oxide nanowire synthesis
(Nature Publishing Group, 2011-07)Rational control over the morphology and the functional properties of inorganic nanostructures has been a long-standing goal in the development of bottom-up device fabrication processes. We report that the geometry of ... -
Face-to-BMI: Using computer vision to infer body mass index on social media
(Association for the Advancement of Artificial Intelligence Press, 2017)A person's weight status can have profound implications on their life, ranging from mental health, to longevity, to financial income. At the societal level, "fat shaming" and other forms of "sizeism" are a growing concern, ... -
Face2Gesture: Translating Facial Expressions Into Robot Movements Through Shared Latent Space Neural Networks
In this work, we present a method for personalizing human-robot interaction by using emotive facial expressions to generate affective robot movements. Movement is an important medium for robots to communicate affective ... -
FaceFolds: Meshed Radiance Manifolds for Efficient Volumetric Rendering of Dynamic Faces
(Association for Computing Machinery, 2024-05-11)3D rendering of dynamic face captures is a challenging problem, and it demands improvements on several fronts---photorealism, efficiency, compatibility, and configurability. We present a novel representation that enables ... -
Facephenes and rainbows: Causal evidence for functional and anatomical specificity of face and color processing in the human brain
(National Academy of Sciences (U.S.), 2017-10)Neuroscientists have long debated whether some regions of the human brain are exclusively engaged in a single specific mental process. Consistent with this view, fMRI has revealed cortical regions that respond selectively ... -
Faceted execution of policy-agnostic programs
(Association for Computing Machinery (ACM), 2013-06)It is important for applications to protect sensitive data. Even for simple confidentiality and integrity policies, it is often difficult for programmers to reason about how the policies should interact and how to enforce ... -
