We analyze and compare two different methods for unsupervised extractive spontaneous speech summarization in the meeting domain. Based on utterance comparison, we introduce an optimal formulation for the widely used greedy maximum marginal relevance (MMR) algorithm. Following the idea that information is spread over the utterances in form of concepts, we describe a system which finds an optimal...

This paper presents an R&D framework used by the National Institute of Standards and Technology (NIST) for biometric technology testing and evaluation. The focus of this paper is on fingerprint-based verification and identification. Since 9-11 the NIST Image Group has been mandated by Congress to run a program for biometric technology assessment and biometric systems certification. Four essenti...

The Internet’s interdomain routing protocol, BGP, is vulnerable to a number of potentially crippling attacks. Many promising cryptography-based solutions have been proposed, but none have been embraced by the necessary communities to garner significant adoption. This is largely due to the difficulty of developing and maintaining the necessary PKI infrastructure and changes to the BGP protocol t...

We have designed a series of computer sessions build around ImageJ (a public-domain software for image analysis), as a practical complement to a two-semester course in image processing. The students are challenged with simple practical imaging problems as they acquire hands-on practice by experimenting with image-processing operators. In the process, they also learn how to program standard imag...

In this note, we present a public domain analytical reactive transport modeling tool (ART3D, version 2.0). The tool is developed in FORTRAN and can be used for solving a system of a set of partial differential equations coupled with a first-order reaction network. ART3D uses a novel analytic solution technique proposed by Clement. The new software includes options for performing Monte Carlo sim...

We present a new open source implementation in the SageMath computer algebra system of algorithms for the numerical solution of linear ODEs with polynomial coefficients. Our code supports regular singular connection problems and provides rigorous error bounds. Extended abstract for a talk given at the 5th International Congress on Mathematical Software (ICMS 2016). Accepted for publication in t...

A Nokia Lumia 1020 cellular phone (Microsoft Corp., Auckland, New Zealand) was configured to image the ova of Ascaris lumbricoides converged into a single field of view but on different focal planes. The phone was programmed to acquire images at different distances and, using public domain computer software, composite images were created that brought all the eggs into sharp focus. This proof of...

Medical training in radiology should be viewed as a continuum that begins in medical school and proceeds throughout the years in practice. Unfortunately, there are significant barriers to providing continuing medical education. One key barrier is the physical separation between the information source and the workplace. A multimedia medical library distributed via wide area networks has been dev...

The paper presents performance results for some components of the new, public-domain version of the SLICOT library (Subroutine Library in Control Theory), in comparison with equivalent computations performed by some Matlab functions included in the Control Toolbox. SLICOT incorporates the new algorithmic developments in numerical linear algebra, implemented in the state-of-the-art software pack...
