Fuzzy extractors are used to generate reliably reproducible randomness from a biased, noisy source. Known constructions of fuzzy extractors are built from a strong extractor, and a secure sketch, a function that transforms a biased noisy secret value into a public value, simultaneously hiding the secret and allowing for error correction. A robust sketch is secure against adversarial modificatio...

Binary relation extraction methods have been widely studied in recent years. However, few methods have been developed for higher n-ary relation extraction. One limiting factor is the effort required to generate training data. For binary relations, one only has to provide a few dozen pairs of entities per relation, as training data. For ternary relations (n=3), each training instance is a triple...

Chicory roots are a valuable source of inulin and other healthy nutrients. The most common direction their industrial processing is instant chicory powder production. Extraction the main process in Conventional extraction methods, which include maceration, percolation screw extractor, have number significant drawbacks, including high capital operating costs, low quality resulting extract, compl...

In light of the elevating pressures toward adopting intensifying technologies, centrifugal extractors are increasingly drawing attention as a promising alternative to traditional extraction equipment. Recently, many fields have applied them in research and that resulted considerable amount information may be hard follow. To keep interested researchers updated, this work presents state-of-the-ar...

The task of keyword extraction aims at capturing expressions (or entities) that best represent the main topics of a document. Given the rapid adoption of these online semantic annotators and their contribution to the growth of the Semantic Web, one important task is to assess their quality. This article presents an evaluation of the quality and stability of semantic annotators on domain-specifi...

Abstract. Here, we proposed an improved version of the deterministic random extractors SEJ and PEJ proposed by R. R. Farashahi in [5] in 2009. By using the Mumford’s representation of a reduced divisor D of the Jacobian J(Fq) of a hyperelliptic curve H of genus 2 with odd characteristic, we extract a perfectly random bit string of the sum of abscissas of rational points on H in the support of D...

Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA) are well known techniques for face recognition. Both PCA and LDA by themselves have good recognition rates. We propose Canonical Correlation Analysis (CCA) for combining two feature extractors to improve the performance of the system, by obtaining the advantages of both. CCA finds the transformation for each extractor dat...

We introduce a new notion flexible extractor. It is a generalization of the standard concept of a two-source-extractor which require each of a sources to have some entropy, flexible extractor requires the sum of sources entropy to exceed fixed value. We distinguish between a strong and a weak flexible extractors and (similarly to two-source-extractors case) prove that every weak flexible extrac...

In this paper, we present an approach to improve microaneurysm detection in digital color fundus images. Instead of following the standard process which considers preprocessing, candidate extraction and classification, we propose a novel approach that combines several preprocessing methods and candidate extractors before the classification step. We ensure high flexibility by using a modular mod...
