In this project we investigate di erent hardware authentication schemes based on Physically Unclonable Functions. We start by analyzing the concepts of a fuzzy extractor and a secure sketch from an information-theoretic perspective. We then present a hardware implementation of a fuzzy extractor which uses the code o set construction with BCH codes. Finally, we propose a new cryptographic protoc...

We show that the maximum matroid-greedoid partition problem is NP-hard to approximate to within 1/2 + ε for any ε > 0, which matches the trivial factor 1/2 approximation algorithm. The main tool in our hardness of approximation result is an extractor code with polynomial rate, alphabet size and list size, together with an efficient algorithm for list-decoding. We show that the recent extractor ...

In this paper we propose a framework for the development of artificial art critics, consisting of an architecture and a validation methodology. The architecture includes two modules: a feature extractor, which performs a pre-processing of the artwork, extracting several measurements and characteristics; and an evaluator, which, based on the output of the feature extractor, classifies the artwor...

IsoQuest used its commercial software product, NetOwl Extractor, for the MUC-7 Named Entity task. The product consists of a high-speed C engine that analyzes text based on a configuration file containing a pattern rule base and lexicon. IsoQuest used the NameTag Configuration to recognize proper names and other key phrases in text, and mapped the product’s extraction tags to the MUC-7 NE tags. ...

In this paper, we describe how we have exploited the advantages of various methods for device recognition and modeling in a layout-to-circuit extractor, called Space. Hence, we have obtained a program that, for different technologies, can quickly translate a large layout into an equivalent network. The network includes layout parasitics of the interconnects and can directly be simulated by vari...

a pressurized fluid extraction (pfe) method for the extraction of pistachio oil was developed using a modified supercritical fluid extractor. the supercritical fluid extraction apparatus was modified to be able to pump liquid solvent and co2 into the extraction vessel alternatively. the experimental results showed that the extraction yield was independent of the extraction pressure. it was also...

Computational terminology has notably evolved since the advent of computers. Regarding the extraction of terms in particular, a large number of resources has been developed: from very general tools to other much more specific acquis ition methodologies. Such acquisition methodologies range from using simple linguistic patterns or frequency counting methods to using much more evolved strategies ...

The mass transfer efficiency and phase flow capacity of a 42.5-cm-diameter (i.d.1 sieve tray extractor has been investigated. The extraction of acetone from water with toluene was chosen because of the large amount of data for comparison with the performance of other devices, and particularly because of available data for a smaller sieve tray extractor tested in the same laboratory. For capacit...
