Abstract A construction of Bourgain [Bou05] gave the first 2-source extractor to break the min-entropy rate 1/2 barrier. In this note, we write an exposition of his result, giving a high level way to view his extractor construction. We also include a proof of a generalization of Vazirani’s XOR lemma that seems interesting in its own right, and an argument (due to Boaz Barak) that shows that any...

This paper reviews our on going e orts on designing a real time vision system The system consists of a real time feature extractor and a relaxation network The lter system is capable of performing multiple D non separable lters multi resolution decomposition and steerable transform The relaxation network is capable of performing various relaxation di usion and minimization operations The paper ...

We propose a new customizable tool, Language Independent Feature Extractor (LIFE), which models the inherent patterns of any language and extracts relevant features of the language. There are two contributions of this work: (1) no labeled data is necessary to train LIFE (It works when a sufficient number of unlabeled documents are given), and (2) LIFE is designed to be applicable to any languag...

Fuzzy extractors are a powerful tool to extract randomness from noisy data. A fuzzy extractor can extract randomness only if the source data is discrete while in practice source data is continuous. Using quantizers to transform continuous data into discrete data is a commonly used solution. However, as far as we know no study has been made of the effect of the quantization strategy on the perfo...

However ATPE has no large-scale industrial applications yet. This is based substantially on very long phase separation times resulting from low interfacial tensions and low density differences between the phases producing intensive and stable emulsions. This causes an increased footprint of the required mixer/settler devices or the application of additional equipment such as energy consuming ce...
