On Selfish and Altruistic Coalition Formation in Cognitive Radio Networks
(IEEE, 2010)We formulate the sensing-throughput tradeoff problem for distributed cognitive radio (CR) networks as a coalition formation game. Formation of coalitions enables the CRs to increase their achievable throughput, under the ... -
On Software Tools and Stack Architectures for Wireless Network Experiments
(2011)Simulation is still the most widely adopted perfor- mance evaluation technique in mobile ad hoc network research, in spite of a growing number of questions about the fidelity of this technique. Implementation-based ... -
On the impact of introducing advanced devices into a cognitive radio network
(IEEE, 2009)Abstract?Cognitive Radio promises better spectrum utilisation through decentralised control, sensing and decision making. The devices are intended to be inexpensive, upgradeable and adaptable. However, introducing ... -
On the internal field correction in far ]infrared absorption of highly polar molecules in neat liquids and dilute solutions
(American Institute of Physics, 1993)Far-infrared absorption spectra for liquid acetone, methylene chloride, acetonitrile, methyl iodide, and their dilute solutions in cyclohexane at 20?C are measured by molecular laser spectrometer. Measurements of dielectric ... -
ON THE STABILITY OF TWO-DIMENSIONAL DISCRETE-SYSTEMS - COMMENT
(ISI Web of Science, 1981)This correspondence shows that independent necessary conditions and sufficient conditions for the asymptotic stability of two-dimensional discrete linear systems presented by Ahmed can be readily obtained from previous results. -
Online Parsing of Sports Coaching Video Through Intrinsic Motion Analysis
(2007)Automatic record and review of actions in sports training sessions is of great benefit to both coach and athlete. Many coaching sessions involve repetition of particular actions to hone technique, such as a swing from ... -
Optical characteristics of ordinary and tunable 1D Si photonic crystals in the mid-infrared range
(2005)Reflection spectra and photonic band gaps (PBGs) for periodic structures consisting of grooved Si infiltrated with nematic liquid crystals (LCs) E7 have been obtained experimentally and by simulation. Periodically grooved ... -
Optical confirmation of biaxial nematic (Nb) phase in a bent-core mesogen
(2009)A bent-core mesogen with different end groups has been studied for different surface conditions in both planar and homeotropic cells using techniques for measuring biaxiality and optical switching. Biaxial nematic phase ... -
Optical properties of diamond films grown by MPCVD method with alternating nanodiamond injection
(Society of Photo-optical Instrumentation Engineers (SPIE), 2005)Transparent polycrystalline diamond films with grain size ranging from a few tens to hundreds of nanometres were prepared on fused silica substrate by Microwave Chemical Plasma Vapour Deposition method (MPCVD). The ... -
Optical properties of grooved silicon structures: theory and experiment
(2011)The reflection spectra of grooved silicon structures consisting of alternating silicon walls and grooves (air channels) with a period of a = 4?6 ?m are studied experimentally and theoretically in the mid-IR spectral range ... -
Optical rotatory power of different phases of an antiferroelectric liquid crystal and implications for models of structure
(American Physical Society, 2001)The investigation of the antiferroelectic liquid crystal (AFLC) was presented. The crystal was found to possess different helical smectic phases identified through a texture under cross-polarizers with a homeotropic alignment ... -
Optical rotatory power, biaxiality and the models of the chiral tilted smectic phases
(2003)Among the chiral tilted smectics, the stable existence has been confirmed in numerous investigations of SmCA*, ~antiferroelectric smectic-CA) SmCF11* (SmCg*), SmCF12* ~antiferroelectric, AF! and SmC* phases. The structures ... -
Optical spectra of two-dimensional photonic crystal bars based on macroporous Si
(2011)Two-dimensional (2D) photonic crystal (PC) bars with 6 and 21 periods were fabricated by simultaneous photoelectrochemical etching of macropores and trenches in a pre-patterned silicon wafer. The structures had square ... -
Optical Study of Platinum-Modified Amorphous Carbon
(Fizika i Tekhnika Poluprovodnikov, 2009)Films of amorphous carbon a-C and a platinum-modified amorphous carbon composite a-C-Pt, produced by magnetron sputtering in a wide range of thicknesses and modifying platinum concentrations in the optimal mode for the ... -
Optimal Schemes for Motion Estimation on Colour Image Sequences
(IEEE Computer Society Press, 1997)This paper describes a method for incorporating the chrominance information when estimating the motion in a colour image sequence. It is based on a maximum likelihood formulation of the motion estimation problem which ... -
