Large electroclinic effect and stability of chiral smectic liquid crystals
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2009)Large electroclinic effect in the smectic-A* phase and stability of smectic-C* variant phases are investigated in detail. Investigation of large electroclinic effect in the smectic-A* phase is one of the recent topics, and ... -
Learning and Reasoning in Cognitive Radio Networks
(2013)Cognitive radio networks challenge the traditional wireless networking paradigm by introducing concepts firmly stemmed into the Artificial Intelligence (AI) field, i.e., learning and reasoning. This fosters optimal resource ... -
Learning Nash Equilibria in Distributed Channel Selection for Frequency-Agile Radios
(2012)Wireless communication networks are evolving towards self- configuring, autonomous and distributed multiagent systems in which nodes are deployed randomly and have to adapt to the en- vironment in which they operate. A ... -
A Lightweight FPGA-based IDS-ECU Architecture for Automotive CAN
(IEEE, 2022)Recent years have seen an exponential rise in complex software-driven functionality in vehicles, leading to a rising number of electronic control units (ECUs), network capabilities, and interfaces. These expanded ... -
A Lightweight Multi-Attack CAN Intrusion Detection System on Hybrid FPGAs
(2022)Rising connectivity in vehicles is enabling new capabilities like connected autonomous driving and advanced driver assistance systems (ADAS) for improving the safety and reliability of next-generation vehicles. This ... -
Line registration of jittered video
(1997)With the imminent widespread availability of digital video broadcasts and the subsequent increase in the demand for broadcast material, image sequence restoration is an increasing source of concern for both archivists and ... -

Linear and nonlinear optical anisotropy of amorphous oxidized silicon films induced by a network of a pores
(American Physical Society, 2006)By thermal oxidation of initially birefringent porous silicon, highly optically transparent films of porous silicon oxide are produced. These films exhibit strong in-plane birefringence, which is twice as high as that of ... -
The linear Monge-Kantorovitch linear colour mapping for example-based colour transfer
(2007)A common task in image editing is to change the colours of a picture to match the desired colour grade of another picture. Finding the correct colour mapping is tricky because it involves numerous interrelated operations, ... -
Liquid crystal display modes in a nontilted bent-core biaxial smectic liquid crystal
(2010)Liquid crystal display (LCD) modes associated with the rotation of the secondary director in nontilted, biaxial smectic phase of an achiral bent-core compound are demonstrated. For LCDs, we find that at least four display ... -
Local Field Effect on Infrared Phonon Frequencies of Thin Dielectric Films
(SPIE, 2003)A number of thin dielectric films deposited onto aluminated glass substrates and onto the materials transparent in the IR range (silicon, KRS-5 and CsI) were investigated using infrared transmission and reflection-absorption ... -
Local Multi-Channel RF Surface Coil versus Body RF Coil Transmission for Cardiac Magnetic Resonance at 3 Tesla: Which Configuration Is Winning the Game?
(2016)Introduction: The purpose of this study was to demonstrate the feasibility and efficiency of cardiac MR at 3 Tesla using local four-channel RF coil transmission and benchmark it against large volume body RF coil ... -
Localised deflicker of moving images
(2006)Brightness fluctuations in sequences are a typical impairment in archive and modern footage. These fluctuations are mainly temporal but they may also present spatial variations across each individual frame. Current deflicker ... -
The localization of focal heart activity via body surface potential measurements: tests in a heterogeneous torso phantom
(2009)The non-invasive localization of focal heart activity via body surface potential measurements (BSPM) could greatly benefit the understanding and treatment of arrhythmic heart diseases. However, the in vivo validation of ... -
Localized relaxation in a glass and the minimum in its orientational polarization contribution
(American Institute of Physics, 2002)The dielectric permittivity and loss spectra of the glassy state of 5-methyl-2-hexanol obtained by quenching it from the liquid state has been studied. In one experiment, the spectra were studied at different temperatures ... -
Localized relaxation's strength and its mimicry of glass-softening thermodynamics.
(American Institute of Physics, 2002)The dielectric relaxation strength of the ? process, ???, in a rigid-molecular glass of 16.6 mol?% chlorobenzene cis-decalin mixture increases slowly with temperature, T, until the glass-softening range is reached, and ... -
Longitudinal complex magnetic susceptibility and relaxation time of superparamagnetic particles with cubic magnetic anisotropy
(American Physical Society, 1998)The magnetic relaxation of single-domain ferromagnetic particles with cubic magnetic anisotropy is treated by averaging the Gilbert-Langevin equation for an individual particle, so that the system of linear differential-recurrence ... -
Low-Complexity Equalization and Detection for OTFS-NOMA
(2023)Orthogonal time frequency space (OTFS) modula- tion has recently emerged as a potential 6G candidate waveform which provides improved performance in high-mobility scenarios. In this paper we investigate the combination ... -
Low-Complexity Joint CFO and Channel Estimation for RIS-aided OFDM Systems
