We study a model of proxy voting where the candidates, voters, and proxies are all located on real line, instead directly, each voter delegates its vote to closest proxy. The goal is find set that theta-representative, which entails for any anywhere favorite candidate within distance theta This property guarantees strong form representation as voters not required be fixed in advance, or even fi...

From 1997 to 1999, the prevalence of Salmonella was assessed at different stages through the pork, poultry, and beef meat production chains. Different dilutions of the initial sample suspension were analyzed to provide a semiquantitative evaluation of Salmonella contamination and to determine the most representative dilution necessary to detect a reduction in prevalence. An average of 300 sampl...

To evaluate the variability of multiphase flow properties of porous media at the pore scale, it is necessary to acquire a number of representative samples of the void-solid structure. While modern x-ray computer tomography has made it possible to extract three-dimensional images of the pore space, assessment of the variability in the inherent material properties is often experimentally not feas...

In this work, we present coding techniques that enable progressive transmission when trellis coded quantization (TCQ) is applied to wavelet coefficients. A method for approximately inverting TCQ in the absence of least significant bits is developed. Results are presented using different rate allocation strategies and different entropy coders. The proposed wavelet-TCQ coder yields excellent codi...

This paper considers the joint problem of dirty-paper and Wyner-Ziv coding with partial host information at the receiver. The rate-distortion and the capacity expressions have been derived for the Gaussian case. It is shown that the availability of the partial host information to the receiver has positive effects to the compression performance and the overall capacity. Moreover, a practical cod...

the molecular phylogenetic trees of 42 representative samples of malaysian pangasiid were constructed using cytochrome c oxidase subunit i (coi). the topologies resulting from molecular analyses, maximum parsimony, maximum likelihood, and bayesian inference, revealed the paraphyly of pangasius genus and monophyly of p. nasutus, p. bocourti, p. micronemus, and p. hypopthalmus with high support v...

the tropical asian cyprinid genus puntius is a major part of the ichthyofauna in southeast asia. systematic status of the genus puntius among cyprinidae, the most prominent freshwater fish all over the world, remain to be substantiated. the molecular phylogenetic analyses derived from recombination activating genesequences (rag2) for 35 representative samples of malaysian puntius and their alli...

With increasing demand for better yield in agricultural areas, soil physical property representative measurements are more and more essential. Nuclear techniques such as computerized tomography (CT) and gamma-ray attenuation (GAT) have been widely employed with this purpose. The soil mass attenuation coefficient (μ(s)) is an important parameter for CT and GAT analysis. When experimentally deter...

CBIR System consist of large datasets with millions of image samples for statistical analysis, hence putting tremendous challenge for pattern recognition techniques, which needs to be more efficient without compromising effectiveness. The image samples are stored in a database in the form of feature vectors. Pattern Recognition Technique requires a high computational burden for learning the dis...
