3D Beam-Steering MIMO Antenna for On-Body IoT Applications
(IEEE, 2023)In this article, a compact 3D beam-steering MIMO antenna operating at 5.75 GHz is proposed for on-body Internet of Things (IoT) applications. The planar antenna comprises a central patch and two concentric annular rings. ... -
Absolute Nothingness - The Kyoto School and Sound Art Practice
(2017)This paper explores how the concept of Absolute Nothingness as developed in the thought of three key Kyoto School thinkers Nishida Kitarō, Tanabe Hajime and Nishitani Keiji has influenced the practice of sound art. The ... -
Adaptation in a Channel Access Game with Private Monitoring
(2013)Under the opportunistic spectrum access paradigm, the shared pool of spectrum bands that the multiple autonomous cognitive radios (CRs) need to compete for is not necessarily homogeneous. The non-homogeneity in channels ... -
Addressing the Mapping Problem in Sonic Information Design through Embodied Image Schemata, Conceptual Metaphors, and Conceptual Blending
(2018)This article explores the mapping problem in parameter mapping sonification: the problem of how to map data to sound in a way that conveys meaning to the listener. We contend that this problem can be addressed by considering ... -
Alignment of liquid crystal E7 in composite photonic crystals based on single crystal silicon
(SPIE, 2005)The orientation of nematic liquid crystal (LC) E7 on the surface of (111) silicon wafers and in the channels of grooved silicon structure has been investigated. Grooved Si is a periodical structure obtained by wet anisotropic ... -
Ambient Data Monitoring w/Generative Music Systems using EC & ML Techniques.
(2018)This is a position paper which describes work in progress to develop an AI/ML driven auditory ambient information system which incorporates generative music techniques and considers some of the factors involved the design ... -
Ambisonic Decoder Test Methodologies based on Loudspeaker Reproduction
(Audio Engineering Society, 2022)The comparative evaluation of the quality of different Ambisonic decoding strategies presents a number of challenges, most notably the lack of a suitable reference signal other than the original, real-world audio scene. ... -
An Analysis of Competition among Autonomous Devices in Multichannel Cognitive Radio Networks
(2012)We investigate an autonomous opportunistic spec- trum access (OSA) strategy for a multichannel cognitive radio (CR) network, where two or more autonomous CRs sense the channels sequentially in some sensing order to find ... -
Anomalous dependence of response time on the electric field in an electroclinic liquid crystal with large induced tilt and polarization
(2009)We investigate the response time of an electroclinic liquid crystal with large induced tilt and polarization (de Vries smectic A*). The response time is found to increase with the increase in electric field up to a threshold ... -
Antiferroelectric and ferroelectric orderings in frustrated chiral tilted smectics and a continuous change from anticlinic SmCA* to synclinic SmC*
(2010)In a frustrated binary-mixture system of ferroelectric and antiferroelectric liquid crystals, where the border line between SmCA* and SmC* in the temperature-concentration phase diagram runs almost parallel to the ordinate ... -
Antiferroelectric dielectric relaxation processes and the interlayer interaction in antiferroelectric liquid crystals
(2008)Antiphase relaxation process of antiferroelectric phase is investigated in binary mixtures of antiferroelectric and ferroelectric liquid crystalline compounds. It is found that the frequency of the antiphase mode ranges ... -
Artificial Intelligence for Dynamical Systems in Wireless Communications: Modeling for the Future
(2021)Dynamical systems are no strangers in wireless communications. Our story will necessarily involve chaos, but not in the terms secure chaotic communications have introduced it: we will look for the chaos, complexity and ... -
Attention-based audio-visual fusion for robust automatic speech recognition
(2018)Automatic speech recognition can potentially benefit from the lip motion patterns, complementing acoustic speech to improve the overall recognition performance, particularly in noise. In this paper we propose an audio-visual ... -
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 ... -
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 ... -
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 ... -
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 Combinatorial Optimisation Approach to the Design of Dual Parented Long-Reach Passive Optical Networks
