We present a comparative study of lexical chain-based summarisation techniques. The aim of this paper is to highlight the effect of lexical chain scoring metrics and sentence extraction techniques on summary generation. We present our own lexical chain-based summarisation system and compare it to other chain-based summarisation systems. We also compare the chain scoring and extraction technique...

Description Testing SNPs and SNP interactions with a genotypic TDT. This package furthermore contains functions for computing pairwise values of LD measures and for identifying LD blocks, as well as functions for setting up matched case pseudo-control genotype data for case-parent trios in order to run trio logic regression, for imputing missing genotypes in trios, for simulating case-parent tr...

Leaks represent a very important hazard for the buildings and they can affect all sorts of building materials and specially wood due to its hygroscopic properties. Excessive moisture content can affect in a negative way building processes such as the installation of wooden floors or the use of wood as a structural material. Moisture meters can provide prompt and non-destructive determination of...

Criteria for the design of an acoustic pulse reflectometer specifically intended for musical instrument research are discussed. Different types of pulse source are considered, and various approaches to the signal processing of the reflected pulse are evaluated., Finally, the practical utility of the technique for instrument designers and manufacturers is discussed.

We prove an existence of a topological decision tree which solves the range searching problem for a system of real polynomials, in other words, the tree finds all feasible signs vectors of these polynomials, with the (topological) complexity logarithmic in the number of signs vectors. This answers the problem posed in [FK98]. 1 Range Searching Problem Let polynomials f1, . . . , fm ∈ R[X1, . . ...

Topic Detection and Tracking (TDT) is a DARPA-sponsored initiative to investigate the state of the art in finding and following new events in a stream of broadcast news stories. The TDT problem consists of three major tasks: (1) segmenting a stream of data, especially recognized speech, into distinct stories; (2) identifying those news stories that are the first to discuss a new event occurring...

As an important task in Topic Detection and Tracking (TDT), Topic tracking aims to monitor story stream arranged in temporal order and identify relevant stories to given topics. On this basis Adaptive Topic Tracking focuses on modifying topic descriptions by learning feedbacks in real time to improve the accuracy of tracking. Many researches have achieved substantial performances in this field,...

Methods of measuring the acoustic behavior of tubular systems can be broadly characterized as steady state measurements, where the measured signals are analyzed in terms of infinite duration sinusoids, and reflectometry measurements which exploit causality to separate the forward and backward going waves in a duct. This paper sets out a multiple microphone reflectometry technique which performs...

In many biological and environmental applications spatially resolved sensing of molecular oxygen is desirable. A powerful tool for distributed measurements is optical time domain reflectometry (OTDR) which is often used in the field of telecommunications. We combine this technique with a novel optical oxygen sensor dye, triangular-[4] phenylene (TP), immobilized in a polymer matrix. The TP lumi...
