Bandwidth-adaptive waveforms for dynamic spectrum access networks
(IEEE, 2008)This paper presents a novel solution to the challenge of waveform bandwidth estimation in DySPAN systems using intentionally embedded cyclostationary signatures. Dynamic spectrum access networks (DySPANs) achieve high ... -
Bayesian example based segmentation using a hybrid energy model
(IEEE, 2007)This paper describes a supervised segmentation algorithmwhich draws inspiration from recent advances in non-parametric texture synthesis. A set of example images which have been segmented a priori are used as a guide ... -
A Bayesian Framework for Recursive Object Removal in Movie Post-Production
(IEEE, 2003)Some of the most convincing film and video effects are created in digital post-production by removing apparatus that supports or manipulates actors and objects. Wires and people, for instance, can be removed by digitally ... -
The Beauty of Twist-Bend Nematic Phase: Fast Switching Domains, First Order Fréedericksz Transition and a Hierarchy of Structures
(2021)The twist-bend nematic phase (NTB) exhibits a complicated hierarchy of structures responsible for several intriguing properties presented here. These are: the observation of a fast electrooptic response, the exhibition of ... -
Biaxial order and a rotation of the minor director in the nematic phase of an organo-siloxane tetrapode by the electric field
(2012)Biaxiality in the nematic phase for a liquid crystalline tetrapode made up of organo-siloxanes mesogens is investigated using polarized infrared spectroscopy. An ordering of the minor director for the homeotropically aligned ... -
Biaxial order parameter in the homologous series of orthogonal bent-core smectic liquid crystals
(2013)The fundamental parameter of the uniaxial liquid crystalline state that governs nearly all of its physical properties is the primary orientational order parameter (S) for the long axes of molecules with respect to the ... -
Bimodal approximation for anomalous diffusion in a potential
(American Physical Society, 2004)Exact and approximate solutions of the fractional diffusion equation for an assembly of fixed-axis dipoles are derived for anomalous noninertial rotational diffusion in a double-well potential. It is shown that knowledge ... -
Blind Source Separation of Speech in Hardware
(IEEE, 2005)This paper presents preliminary work on a hardware implementation of a source separation algorithm employing time-frequency masking methods. DUET (Degenerate Unmixing Estimation Technique) has previously been shown to ... -
Blockchain, what time is it? Trustless Datetime Synchronization for IoT
(2020)Time synchronization among IoT devices is a fundamental requirement for efficient and reliable communication on a global scale. Common synchronization schemes such as NTP operate on a trust-based client-server model, which ... -
Blotch and scratch removal in archived film using a semi-transparent corruption model and a ground-truth generation technique
(2013)This paper has two main contributions. The first is a Bayesian framework for removing two common types of degradations on video known as blotches and line scratches. Most removal techniques assume complete obliteration of ... -
Blotch and scratch removal in archived film using a semi-transparent corruption model and a ground-truth generation technique
(Springer, 2013)This paper has two main contributions. The first is a Bayesian framework for removing two common types of degradations on video known as blotches and line scratches. Most removal techniques assume complete obliteration of ... -
Broad band infrared spectroscopy of grooved silicon
(SPIE, 2005)Grooved silicon (gr-Si) structures with a period of few micrometers, which were formed by anisotropic etching of (110) Si wafers, have been investigated by means of broad band infrared (IR) and submillimeter transmission ... -
Browsing sports video: trends in sports-related indexing and retrieval work
(IEEE, 2006)This paper aims to identify the current trends in sports-based indexing and retrieval work. It discusses the essential building blocks for any semantic-level retrieval system and acts as a case study in content analysis ... -
Build automation and runtime abstraction for partial reconfiguration on Xilinx Zynq Ultrascale+
(2020)Partial reconfiguration (PR) is fundamental to building adaptive systems on modern FPGA SoCs, where hardware can be adapted dynamically at runtime. Vendor supported reconfiguration is performance ... -
Caching to the Sky: Performance Analysis of Cache-Assisted CoMP for Cellular-Connected UAVs
(2019)Providing connectivity to aerial users, such as cellular-connected unmanned aerial vehicles (UAVs) or flying taxis, is a key challenge for tomorrow’s cellular systems. In this paper, the use of ... -
Calculation of the rise transient and relaxation time of the induced dipole Kerr effect
(American Physical Society, 1996)The exact calculation of the rise transient of the birefringence and the corresponding relaxation times by different theoretical methods is described, in particular the Kerr-effect response of an assembly of nonpolar but ... -
Carrier Aggregation as a Repeated Game: Learning Algorithms for Efficient Convergence to a Nash Equilibrium
(2013)Carrier aggregation is a key feature of next generation wireless networks to deliver high-bandwidth links. This paper studies carrier aggregation for au- tonomous networks operating in shared spectrum. In our model, ... -
A case for FPGA-based accelerators for energy-efficient motion picture video processing
(SPIE, 2023)In recent years, computing-based video processing workflows have become an integral part of the motion picture industry. These workloads are highly data- and compute-intensive, requiring capable hardware to achieve ... -
Causality considerations for missing data reconstruction in image sequences
(IEEE, 1997)The 3D autoregressive (AR) model with a non-causal support region has been successfully employed in the reconstruction of texture and missing regions in image sequences. This paper discusses the causality considerations ...
