Recently, studying social networks plays a significant role in many applications of social network analysis, from the studying the characterization of network to that of financial applications. Due to the large data and privacy issues of social network services, there is only a limited local access to whole network data in a reasonable amount of time. Therefore, network sampling arises to study...

Background: Staffs may suffer from high job stress and low quality of the marital relationship. Constructive skills can have a positive impact on them. Thus, the aim of the current research was to investigate the effectiveness of relationship enhancement (RE) approach training on job stress and quality of marital relationship among staffs of the Municipality of Karaj, Iran. Materials and Metho...

A robust and oblivious audio watermarking based on quantization of wavelet coefficients is proposed in this paper. Watermark data is embedded by quantizing large wavelet coefficient in absolute value of high frequency detail sub-band at the third level wavelet transform. The watermark can be extracted without using the host signal. Experimental results show that the proposed method has good imp...

Tree ensemble or combining methods that use re-sampling technique have been highlighted recently in Statistical classification and Data mining. In this paper, we propose a new ensemble method in decision trees that utilizes systematic patterns of classification. The new method improved the prediction accuracy of a single decision tree algorithm. It is also observed that this method performs rea...

A chromium electroplating bath with the ability to produce homogenous mist was used to evaluate parameters influencing hexavalent chromium (Cr+6) mist sampling methods. The results of 48 Cr+6mist samples collected using the U.S. National Institute for Occupational Safety and Health method 7600...

T h e re is considerable concern about increasing rates of dru g related mortality in the UK. Evidence has suggested that recently released offenders are at a high risk of dying from dru g related causes. This study provides estimates of the rates of mortality amongst re c e n t l y released prisoners in England and Wales and provides some evidence of the risk factors associated with this group...

An audio watermarking system based on multiple echoes hiding is designed for frequency modulation (FM) broadcasting. The embedded watermarking information of 16 bits can be recovered from the receiver by recording the broadcast for any 1 second. On the premise of guaranteeing the high imperceptibility and robustness, the multiple echoes scheme we proposed has a higher capacity. The proposed sys...

This paper deals with the task of tracking several similar looking athletes during a competition, using only a single camera. Due to the wide range of possible motions, non-rigid shape changes and mutual occlusions the tracking situations can become quite complex. We propose a novel method to use a high dimensional motion model for a particle filter without drastic increase in runtime. Integral...

Determining the significance of slope differences is a common requirement in studies of self-thinning, ontogeny and sexual dimorphism, among others. This has long been carried out testing for the overlap of the bootstrapped 95% confidence intervals of the slopes. However, the numerical random re-sampling with repetition favours the occurrence of re-combinations yielding largely diverging slopes...

Interpolation is one of the widely used in many applications Image processing such as scaling, re-sampling and re-targeting. The Interpolation which estimates unknown target pixel value from surrounding neighborhood known pixels, the quality of Interpolation algorithm depends on number of pixels used in estimation. An image consists of edge and smooth pixels. Hence To exploiting content of the ...
