Thermally activated escape rates of uniaxial spin systems with transverse field: uniaxial crossovers.
(American Physical Society, 2000)Classical escape rates of uniaxial spin systems are characterized by a prefactor differing from and much smaller than that of the particle problem, since the maximum of the spin energy is attained everywhere on the line ... -
Thermally activated relaxation time of a single domain ferromagnetic particle subjected to a uniform field at an oblique angle to the easy axis: Comparison with experimental observations
(American Physical Society, 1998)New asymptotes of the relaxation time of the magnetic moment of a single domain particle with a uniform magnetic field applied at an oblique angle to the easy axis (in excellent agreement with exact numerical results from ... -
Thermotropic Biaxial Nematic Phase in Liquid Crystalline Organo-Siloxane Tetrapodes
(2004)Infrared absorbance measurements have been carried out on two liquid crystalline organo-siloxane tetrapodes. Results unambiguously show the existence of a biaxial nematic phase below a uniaxial nematic phase. The three ... -
Threshold learning from samples drawn from the null hypothesis for the generalized likelihood ratio cusum test
(2005)Although optimality of sequential tests for the detection of a change in the parameter of a model has been widely discussed, the test parameter tuning is still an issue. In this communication, we propose a learning strategy ... -
Throughput-Efficient Dynamic Coalition Formation in Distributed Cognitive Radio Networks
(2010)We formulate the problem of distributed throughput-efficient sensing in cognitive radio (CR) networks as a dynamic coalition formation game based on a Markovian model. The proposed coalition formation enables the CRs to ... -
Time and Frequency Synchronization for OTFS
(2022)In this letter, we propose timing offset (TO) and carrier frequency offset (CFO) estimators for orthogonal time frequency space modulation (OTFS). The proposed estimators do not require any additional training overheads ... -
Tip-enhanced secondary emission of a semiconductor quantum dot
(American Institute of Physics, 2008)The interaction between interface plasmons within a doped substrate and quantum dot electrons or holes has been theoretically studied in double heterostructures based on covalent semiconductors. The interface plasmon modes, ... -
Towards a fluid spectrum market for exclusive usage rights
(IEEE, 2007)This paper focuses on highly fluid markets for trading exclusive spectrum usage-rights. The purpose of the paper is to underline the need for flexible usage-rights policies, as a core facilitator of such markets as well ... -
Towards a Hardware Realization of Time-Frequency Source Separation of Speech
(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 ... -
Towards predicting dialog acts from previous speakers' non-verbal cues
(2017)In studies of response times during conversational turn-taking, a modal time of 200 ms has been observed to be a universal value that exists across languages and cross-culturally. This 200 ms value is also seen as the limit ... -
Traffic-Aware Channel Assignment for Multi-Radio Wireless Networks
(2012)This paper studies channel assignment in multi-hop wireless networks in which nodes are equipped with multiple radios, each of which can be assigned to a channel. We argue for an approach that rst assigns channels ... -
Transformation of one-dimensional silicon photonic crystal into Fabry-Perot resonator
(2011)The model of transformation of one-dimensional, high-contrast silicon photonic crystal (PC) into a Fabry-Perot resonator is considered. This transformation is achieved either by decreasing the number of periods up to 1.5 ... -

Transverse complex magnetic susceptibility of single-domain ferromagnetic particles with uniaxial anisotropy subjected to a longitudinal uniform magnetic field
(American Physical Society, 1997)The infinite hierarchy of differential-recurrence relations for the equilibrium transverse correlation functions appropriate to magnetic relaxation of single-domain ferromagnetic particles with uniaxial anisotropy subjected ... -
Truncated Turbo Equalizer with SIC for OTFS
(2023)Orthogonal time frequency space (OTFS) is a promising candidate waveform for the next generation wireless communication systems. OTFS places data in the delay-Doppler (DD) domain, which simplifies channel estimation in ... -
Tunable microcavity based on macroporous silicon: feasibility of fabrication
(IEEE, 2013-08-16)Simultaneous electrochemical etching of deep pores and trenches in silicon was used to fabricate a two-dimensional, photonic crystal slab (PCS). The structure consists of five rows of macro-pores on both sides of a ... -
Tunable photonic structures based on silicon and liquid crystals
(2008)This paper is focused on the design, fabrication and characterization of the conventional and tunable photonic devices based on grooved silicon, serving as one-dimensional (1D) photonic crystal. The advantages of these ... -
Two kinds of the smectic-C subphases in a liquid crystal and their relative stability dependent on the enantiomeric excess as elucidated by the electric field induced birefringence experiment
(The American Physical Society, 2005)The electric-field-induced birefringence has been investigated by using a photoelastic modulator, with a view to obtaining a molecular model for the subphases produced by the frustration between ferroelectricity and ... -
Two layer segmentation for handling pathological motion in degraded post production media
(IEEE, 2004)The paper presents a mechanism for dealing with incorrect motion estimation in degraded post production image sequences. This tends to be caused by pathological motion (a combination of motion blur, complex foreground ... -
Ultra-fast 1+1 protection in 10 Gb/s symmetric long reach PON
