The purpose of this study is to compare the changing behavior of two counting methods (whole counting and whole-normalized counting) and inflation rate at country level research productivity and impact. For this, publication data on tribology research published between 1998 and 2012 from SCOPUS has been used. Only internationally collaborated papers are considered for comparison between two cou...

The objective of this research was to develop a screening inventory for Thai Muslims spouses at risk of domestic violence behaviors in Satun Province. The study was conducted with the subject group of 1,140 households consisting of 2,280 people recruited through multi-stage sampling. The data were analyzed using the R program to find out the indexes of item-objective congruence, t-values, corre...

Multi-channel acoustic echo cancellation is basically composed of two parts. One part is a multi-channel system identification problem which is nontrivial to solve. The other part, which is also nontrivial, is the so-called double-talk detection problem. Nearend speech detection is based on a test statistic. Recently, a new double-talk test statistic based on the normalized cross-correlation ve...

This paper presents an evaluation of different types and families of multiwavelets in stereo correspondence matching. Different multiwavelet families with different filter types such as balanced versus unbalanced, symmetricsymmetric versus symmetric-antisymmetric are used. Normalized cross correlation is employed to find the best correspondence points and generate a disparity map. In the case o...

A sensitivity analysis of a single-server, infinite-buffer queue with correlated arrivals and correlated service times is performed. We study and compare the isolated impact of (normalized) marginal moments and (normalized) correlation structures of the arrival and service processes on the performance measures of such a queue. For these correlated processes, we use Markovian arrival processes o...

In order to accelerate the motion estimation process, the normalized partial distortion search algorithm calculates the partial distortion by constantly selecting specific pixels from every sub-macroblock to early reject the incorrect motion vector. However, these selected pixels are supposed that the pixels’ values of sub-macroblock are uniform distribution. This paper proposes a partial disto...

Multichannel acoustic echo cancellation is basically composed of two parts. One part is a multichannel system identification problem which is nontrivial to solve. The other part, which is also nontrivial, is the so-called double-talk detection problem. Near-end speech detection is based on a test statistic. Recently, a new double-talk test statistic based on the normalized cross-correlation vec...

This paper presents the 3-D terrain reconstruction with aerial photography. The results of 3-D reconstruction using intensity-based matching and hybrid intensity-based and epipolar geometry approach matching are shown and compared. The intensity-based image matching uses maximum normalized cross correlation to find the displacement vector between two images. This method can overcome the effect ...

A Kalman/map filtering (KMF)-aided fast normalized cross correlation (FNCC)-based Wi-Fi fingerprinting location sensing system is proposed in this paper. Compared with conventional neighbor selection algorithms that calculate localization results with received signal strength (RSS) mean samples, the proposed FNCC algorithm makes use of all the on-line RSS samples and reference point RSS variati...
