V-shaped electro-optic response observed in a chiral ferroelectric smectic liquid crystal
(2008)We report on the observation of V-shaped switching in a ferroelectric liquid crystal cell over a wide range of temperatures. Results of the optical transmittance in the visible region give us the helical pitch for various ... -
Variation of features of interframe dependent HMM for speech recognition
(1998)The effects are explored of using different dynamic features in conjunction with an HMM that permits a dependency on both preceeding and succeeding frames. In particular, features which capture dynamic information are ... -
A Variational Bayes Approach to Decoding in a Phase-Uncertain Digital Receiver
(2011)This paper presents a Bayesian approach to symbol and phase inference in a phase-unsynchronized digital receiver. It primarily extends [Quinn 2011] to the multi-symbol case, using the variational Bayes (VB) approximation ... -
Various liquid crystalline phases structural analysis using resonant x-ray scattering
(2022)Chiral smectic liquid crystals have a paraelectric phase, a ferroelectric phase, and an antiferroelectric phase. Therefore, multiple phases called secondary phases appear, and sequential phase transitions are observed. ... -
VEGa: A high performance vehicular Ethernet gateway on hybrid FPGA
(2017)Modern vehicles employ a large amount of distributed computation and require the underlying communication scheme to provide high bandwidth and low latency. Existing communication protocols like Controller Area Network (CAN) ... -
Vehicular Networks: Embracing Wireless Heterogeneous Communications through Vertical Handover
(2013)By taking advantage of the ever growing deployment of wireless networks, the automotive industry is increasingly enabling vehicles to communicate with one another and with the infrastructure, with benefits to information ... -
Video Matting Using Motion Extended GrabCut.
(IEEE, 2008)GrabCut is perhaps the most powerful semi-automatic algorithm for matting presented to date. In its existing form, it is not suitable for video object segmentation. This paper considers major extensions that make it ... -
ViSQOL: an objective speech quality model
(2015)This paper presents an objective speech quality model, ViSQOL, the Virtual Speech Quality Objective Listener. It is a signal-based, full-reference, intrusive metric that models human speech quality perception using a ... -
ViSQOL: The Virtual Speech Quality Objective Listener
(2012)A model of human speech quality perception has been developed to provide an objective measure for predicting subjective quality assessments. The Virtual Speech Quality Objective Listener (ViSQOL) model is a signal based ... -
ViSQOLAudio: An objective audio quality metric for low bitrate codecs
(2015)Streaming services seek to optimise their use of bandwidthacross audio and visual channels to maximise the quality of experiencefor users. This letter evaluates whether objective quality metrics can pre-dict the audio ... -
A Viterbi tracker for local features
(SPIE, 2010)The long term tracking of sparse local features in an image is important for many applications including camera calibration for stereo applications, camera or global motion estimation and people surveillance. The majority ... -
Vowel Formant Profiles and Image Schemata and Auditory Display
(2018)This paper presents two evaluations intended to examine if listeners are more likely to associate certain vowel formant profiles with specific data types in an auditory display context. The data types and sounds chosen ... -
Watermarking digital images for copyright protection
(IEE, 1996)A watermark is an invisible mark placed on an image that is designed to identify both the source of an image as well as its intended recipient. The authors present an overview of watermarking techniques and demonstrate a ... -
Watermarking digital images for copyright protection
(IEE, 1995)A watermark is all invisible mark placed on an image that can only be detected when the image is compared with the original. This mark is designed to identify both the source of a document as well as its intended recipient. ... -
A wavelet-based Bayesian framework for 3D object segmentation in microscopy
(2012)In confocal microscopy, target objects are labeled with fluorescent markers in the living specimen, and usually appear with irregular brightness in the observed images. Also, due to the existence of out-of-focus objects ... -
Whispering gallery mode emission from photonic microtubes
(IEEE, 2006)We have found cylindrical glass microtubes can be formed by vacuum assisted filtration using a micro-channel glass matrix followed by thermal treatment of the material. The microtubes are strongly luminescent and exhibit ... -
Whispering-gallery modes in photonic tubes
(Society of Photo-optical Instrumentation Engineers (SPIE), 2007)A new method has been developed to fabricate microtube resonators with strong whispering-gallery-mode emission and quality factors up to 3000. -
Whitespace Networks Relying on Dynamic Control Channels
(2013)The emergence of whitespace networks, and whitespace communications in general, provides an opportunity to, at least partially, meet the ever-growing demand for mobile data communication. Most of the whitespace network ...
