Bessel functionsBased reconstruction of nonuniformly sampled diffraction fields
(2007)A discrete computational model for the diffraction process is essential in forward problems related to holographic TV. The model must be as general as possible, since the shape of the displayed objects does not bear any ... 
Comparison of surfacemodeling techniques
(IEEE, Piscataway, NJ, United States, 1997)Solution techniques based on surface integral equations are widely used in computational electromagnetics. The accurate surface models increase the accuracy solutions by using exact and flattriangulation models for a ... 
Computationally efficient wavelet affine invariant functions for 2D object recognition
(IEEE, 2003)In this paper, an affine invariant function is presented for object recognition from wavelet coefficients of the object boundary. In previous works, undecimated wavelet transform was used for affine invariant functions. ... 
Contactfree measurement of respiratory rate using infrared and vibration sensors
(Elsevier BV, 2015)Respiratory rate is an essential parameter in many practical applications such as apnea detection, patient monitoring, and elderly people monitoring. In this paper, we describe a novel method and a contactfree multimodal ... 
Denoising using projections onto the epigraph set of convex cost functions
(Institute of Electrical and Electronics Engineers Inc., 2014)A new denoising algorithm based on orthogonal projections onto the epigraph set of a convex cost function is presented. In this algorithm, the dimension of the minimization problem is lifted by one and feasibility sets ... 
Economic design of EWMA control charts based on loss function
(Elsevier, 2009)For monitoring the stability of a process, various control charts based on exponentially weighted moving average (EWMA) statistics have been proposed in the literature. We study the economic design of EWMAbased mean and ... 
An efficient method for electromagnetic characterization of 2D geometries in stratified media
(IEEE, 2002)A numerically efficient technique, based on the spectraldomain method of moments (MoM) in conjunction with the generalized penciloffunctions (GPOF) method, is developed for the characterization of twodimensional ... 
Energetic efficient synthesis of general mutual intensity distribution
(Institute of Physics Publishing, 2000)The mutual intensity distribution of a light beam may contain available information. The task of encoding a given mutual intensity distribution is addressed in this paper. Various approaches for encoding the mutual intensity ... 
Exact calculation of blocking probabilities for bufferless optical burst switched links with partial wavelength conversion
(2004)In this paper, we study the blocking probabilities in a wavelength division multiplexingbased asynchronous bufferless optical burst switch equipped with a bank of tuneable wavelength converters that is shared per output ... 
The fractional fourier transform and its applications to image representation and beamforming
(2003)The ath order fractional Fourier transform operator is the ath power of the ordinary Fourier transform operator. We provide a brief introduction to the fractional Fourier transform, discuss some of its more important ... 
Guessing subject to distortion
(Institute of Electrical and Electronics Engineers, 199805)We investigate the problem of guessing a random vector X within distortion level D. Our aim is to characterize the best attainable performance in the sense of minimizing, in some probabilistic sense, the number of required ... 
Improving the accuracy of the MFIE with the choice of basis functions
(2004)The accuracy of the magneticfield integral equation (MFIE) for the Method of Moments (MOM) and fastmultiplemethod (FMM) solutions of the electromagnetic scattering problems modeled by abitrary planar triangulations is ... 
Influence function based Gaussianity tests for detection of microcalcifications in mammogram images
(IEEE, Los Alamitos, CA, United States, 1999)In this paper, computeraided diagnosis of microcalcifications in mammogram images is considered. Microcalcification clusters are an early sign of breast cancer. Microcalcifications appear as single bright spots in mammogram ... 
An inventory problem with two randomly available suppliers
(Institute for Operations Research and the Management Sciences, 1997)This paper considers a stochastic inventory model in which supply availability is subject to random fluctuations that may arise due to machine breakdowns, strikes, embargoes, etc. It is assumed that the inventory manager ... 
Investigation of the inaccuracy of the MFIE discretized with the RWG basis functions
(2004)The inaccuracy of the magneticfield integral equation (MFIE) discretized with the RaoWiltonGlisson (RWG) basis functions is discussed. The electricfield integral equation (EFIE) gives accurate results with the usage ... 
Joint sourcechannel coding and guessing
(IEEE, Piscataway, NJ, United States, 1997)We consider the joint sourcechannel guessing problem, define measures of optimum performance, and give singleletter characterizations. As an application, sequential decoding is considered. 
Language evolution and information theory
(2004)The use of Nowak's model to study the language evolution and to settle a conjecture by Nowak was discussed. These models explained the ways by which natural selection can lead to the gradual emergence of human language. ... 
Marginal allocation algorithm for nonseparable functions
(Taylor & Francis, 1999)Marginal allocation algorithm is implemented to discrete allocation problems with nonseparable objective functions subject to a single linear constraint. A Lagrangian analysis shows that the algorithm generates a sequence ...
