In the study, the effectiveness of combinations of cepstral features, channel compensation techniques, and different local distances in the Dynamic Time Warping (DTW) algorithm is experimentally evaluated in the text-dependent speaker identification task. The training and the testing has been done with noisy telephone speech (short phrases in Bulgarian with length of about 2 seconds) selected f...

There comes Fliess’s local realization theorem which provides criteria for the coefficients of such a series to be based on a non linear dynamic system. The rational series and the polynomials that are recognized by weighted automata (with or without cycles) meet these criteria (rank finiteness of the Lie–Hankel matrix, polynomial growth of coefficients). In the case of polynomials indeed, this...

The feasibility pump is a recent, highly successful heuristic for general mixed integer linear programming problems. We show that the feasibility pump heuristic can be interpreted as a discrete version of the proximal point algorithm. In doing so, we extend and generalize some of the fundamental results in this area to provide new supporting theory. We show that feasibility pump algorithms impl...

This paper investigates the use of Euclidean invariant features in a generalization of iterative closest point registration of range images. Pointwise correspondences are chosen as the closest point with respect to a weighted linear combination of positional and feature distances. It is shown that under ideal noise-free conditions, correspondences formed using this distance function are correct...

The aim of this study is to explore the attitude of local residents towards the socio, economic and environmental impact of tourism development in Madhupur and Sirajgonj upozilla of Bangladesh. The number of respondents was 384 and data were collected through a self-centered survey method. A convenience sampling technique was taken to select the sample. Data were collected using both primary an...

Due to abundant spectral information contained in the hyperspectral images, they are suitable data for anomalous targets detection. The use of spatial features in addition to spectral ones can improve the anomaly detection performance. An anomaly detector, called nonparametric spectral-spatial detector (NSSD), is proposed in this work which utilizes the benefits of spatial features and local st...

in this paper, we generalize a theorem of shao [12] by assuming that is a sequence of linear negatively dependent random variables. also, we extend some theorems of chao [6] and thrum [14]. it is shown by an elementary method that for linear negatively dependent identically random variables with finite -th absolute moment the weighted sums converge to zero as where and is an array of real numbe...

A class of nonlinear digital filters, called the threshold Boolean filter (TBF), is introduced. The TBF is defined by a Boolean function on the binary domain and is a natural extension of stack filters. Multilevel representations of a TBF corresponding to a Boolean function are derived; a TBF can be represented either as a sum of “local minimum-local maximum” terms or as an adaptive linear comb...

This work focuses on the mathematical combination of magnetogasdynamics (MGD) and Dunn Kang chemical kinetic model with a multi-component Harten–Lax–van Leer Contact (HLLC) local Riemann solver using high-order interpolation schemes. Due to nature nearly hypersonic, unsteady, viscous, reacting MGD flows, gas dissociates which is taken into account 11 species 26 reactions along temperature depen...
