Magnetization dynamics of two interacting spins in an external magnetic field
(American Physical Society, 2005)The longitudinal relaxation time of the magnetization of a system of two exchange coupled spins subjected to a strong magnetic field is calculated exactly by averaging the stochastic Gilbert-Landau-Lifshitz equation for ... -
Microstructural investigation supporting an abrupt stress induced transformation in amorphous carbon films
(American Institute of Physics, 2009)The intrinsic stress of carbon thin films deposited by filtered cathodic arc was investigated as a function of ion energy and Ar background gas pressure. The microstructure of the films was analyzed using transmission ... -
Microwave absorbent properties of nanosized cobalt ferrite powders prepared by coprecipitation and subjected to different thermal treatments
(Elsevier, 2011)Cobalt ferrite nanopowders were produced by means of two methods using a common precipitating agent. After precipitation, in the first method the cobalt ferrite was calcined, whilst in the second method the precipitation ... -
Mobile context aware stories
(IEEE, 2002)An interactive narrative is a story that is shaped by digital technology and that allows the dynamic presentation of scenes or sequences based on input from the user. In this paper we present a new foundation for interactive ... -
A model for human skin impedance during surface functional neuromuscular stimulation
(IEEE, 1999)A new mathematical model for the bulk electrical impedance of human skin is presented. In particular this model describes the impedance of skin during surface functional neuromuscular stimulation (FNS) with square stimulation ... -
Molecular tilt angle and order parameter of low molar mass ferroelectric liquid crystal using IR spectroscopy
(1996)Fourier transform infrared spectroscopy of a ferroelectric liquid-crystalline material: 4-(3)-(S)- methyl-2-(S)-chloropentanoyloxy-4'-octyloxy-biphenyl has been investigated in the wavenumber range 450 - 4000 cm-1 for ... -
Motion model selection in tracking humans
(IET, 2006)The performance of many human tracking algorithms rely on accurate motion models. Due to the nature of human motion it is often difficult to determine the suitability of a chosen model. It is typically the case that over ... -
Multi-channel, Si-Liquid Crystal Filter, with Fine Tuning Capability of Individual Channels for Compensation of Fabrication Tolerances
(2012)In this study, a technique for the optimization of the optical characteristics of multi-channel filters after fabrication is proposed. The multi-channel filter under consideration is based on a Si photonic crystal (PhC), ... -
A multi-hop ARQ protocol for underwater acoustic networks
(IEEE, 2007)Underwater acoustic networks are envisaged to be the enabling technology for oceanographic data collection, pollution monitoring, offshore exploration and tactical surveillance applications. Unique characteristics of ... -
Multi-operator connectivity sharing for reliable networks: a data-driven risk analysis
(2021)A key distinction between today’s and future networks is the appetite for reliable communication to support emerging critical-communication services. In this paper, we study multi-operator connectivity as a form of redundancy ... -
N-dimensional probability density function transfer and its aplication to colour transfer
(2005)This article proposes an original method to estimate a continuous transformation that maps one N-dimensional distribution to another. The method is iterative, non-linear, and is shown to converge. Only 1D marginal distribution ... -
Network Sharing for Reliable Networks: A Data-Driven Study
(2020)The next generation of mobile networks will bring an appetite for reliable communication, which enables emerging critical-communication services. In this paper, we present network sharing between operators as a way to ... -
Neurosciences and Wireless Networks: The Potential of Brain-Type Communications and Their Applications
(2021)This paper presents the first comprehensive tutorial on a promising research field located at the frontier of two well-established domains, neurosciences and wireless communications, motivated by the ongoing efforts to ... -
A noise adaptive symbol timing synchronization algorithm for software radio receivers
(2004)Software radio promises tremendous benefits from both commercial and military standpoints. Currently, there are a number of different 'shades' of software radio based on the use of FPGAs, DSP chips or general-purpose ... -
Non-Contact Radio Frequency Level Sensor Based on Wheeler Cap
(2023)In this paper, we propose a novel non-contact liquid level sensor based on the Wheeler cap. The sensor utilizes an electrically small antenna operating at 276 MHz enclosed within a metal cap, in conjunction with the liquid ... -
Nonexponential dielectric relaxation dynamics in supercooled liquid and glassy states of isoamyl bromide and 2-methylpentane mixtures
(American Institute of Physics, 2001)The dielectric spectra of mixtures of the polar solute isoamyl bromide in 2-methylpentane have been investigated in the frequency range 1 mHz to 1 MHz and in the temperature range approaching the glass transition temperature. ...
