A hospital-based cross sectoral serological study was undertaken in Chittagong metropolitan city – the second largest city in Bangladesh to assess the current receptivity of the country for DF/DHF, using the haemagglutination inhibition test (HI). Samples were taken from the suspected cases of dengue infection following the inclusion and exclusion criteria. A total of 253 paired samples was col...
In this article, distributed interleave-division multiplexing space-time codes (dIDM-STCs) are applied for multi-user two-hop decode-and-forward (DF) relay networks. In case of decoding errors at the relays which propagate to the destination, severe performance degradations can occur as the original detection scheme for common IDM-STCs does not take any reliability information about the first h...
In our real time experimental analysis the acoustic sensor estimates the specific target (elephant) coverage localization at 3 different types of forests. The proposed method consists of estimating Direction of Arrival Estimation using partial hyperbolic circular array and also identified few external factors affecting outdoor propagation and acoustic source localization in forest. We already i...

Let (Mt)t∈IR+ be a real locally integrable martingale starting from 0, with jumps of height one on a probability space (Ω, (Ft),F∞, P ), with the decomposition M = M c + X − ν, where (M c t )t∈IR+ is the continuous part of (Mt)t∈IR+ , (Xt)t∈IR+ is a point process on IR+ independent of (M c t )t∈IR+ , and (νt)t∈IR+ is the compensator of (Xt)t∈IR+ . Let β =< M c > denote the quadratic variation o...
Because of the infrared renormalons, it is difficult to get power accuracy in the traditional approach to the Wilson’s operator product expansion. Based on a new perturbative renormalization scheme for power-divergent operators, I propose a practical version of the OPE that allows to calculate power corrections to desired accuracy. The method is applied to the expansion of the vector-current co...
In this paper, an array aperture extension algorithm is developed for two-dimensional (2-D) direction-of-arrival (DOA) estimation with L-shaped array. We enlarge the dimension of the covariance matrix by using the rotational invariance in conjunction with the property that the signal covariance matrix is real diagonal matrix. Estimation of DOAs is performed by processing this larger dimensional...
This paper addresses asymptotically (in the number of measurements) minimum variance (AMV) estimators within the class of estimators based on a mixture of real and complexvalued sequence of statistics whose first covariance of its asymptotic distribution is singular. Thanks to two conditions, we extend the standard AMV estimator. We prove that these conditions are satisfied for the estimates of...
In a previous work, the authors have introduced a Mixture of Laplacians model in order to cluster the observed data into the sound sources that exist in an underdetermined two-sensor setup. Since the assumed linear support of the ordinary Laplacian distribution is not valid to model angular quantities, such as the Direction of Arrival to the set of sensors, the authors investigate the performan...
