Evolving an existing software system is fundamentally different from developing one from scratch. Consequently, tools to support evolution must go beyond traditional development tools. This paper describes the Esprit de Corps Suite (EDCS) of software evolution tools. EDCS supports the Mission Oriented Architectural Legacy Evolution (MORALE) software reengineering process. The paper briefly desc...

We examine the effect of inhomogeneous reionization on the galaxy power spectrum and the consequences for probing dark energy. To model feedback during reionization, we apply an ansatz setting the galaxy overdensity proportional to the underlying ionization field. Thus, inhomogeneous reionization may leave an imprint in the galaxy power spectrum. We evolve this imprint to low redshift and use t...

One of the aims of establishing the OpenMath standard is to support Internet Accessible Mathematical Computation (IAMC). The Esprit OpenMath project is, in part, concerned with determining the details of how this is to be done. In this paper we explore the framework proposed by Wang as a standard approach to IAMC and identify issues and design principles to guide further development of an IAMC ...

A three-dimensional (3-D) source localization algorithm of joint elevation, azimuth angles and range estimation for the mixed near-field (NF) and far-field (FF) sources is presented in this paper. We first estimate the elevation angles of all mixed sources by using the generalized ESPRIT method. With the elevation angle estimates, the range parameters of all mixed sources are obtained, and then...

This paper describes a strategy for mixed-initiative spoken dialogue management. The strategy is outlined, and two experiments are carried out to investigate the methodology. The experiments are carried out within the Esprit OVID1project. The OVID project is concerned with the development of trial applications within automated banking services [1]. Among other things, the OVID user specificatio...

1 M o t i v a t i o n s Performance evaluation is a central issue in the design of complex real-time systems. The general situation we consider in this paper can be described as follows : 1 / T h e real-time system in consideration consists of a finite collection of tasks. Tasks are triggered by events originating from both the environment and the system itself, depending on its internal state....

This DISC Working Paper present a first outline of a systematic approach to the evaluation of spoken language dialogue systems (SLDSs) and their components. The approach is illustrated for the case of dialogue manager evaluation. The basic components of the approach are (a) a model of the core properties of the SLDS or component to be evaluated; (b) a set of evaluation criteria which have been ...

good sound and good value, properties they share with a number of other Canadian makes who have taken advantage of Canada’s National Research Council facilities in Ottawa. In fact, the first components I bought specifically for what is now my multichannel system were Paradigm Esprit BP speakers, which had impressed me at a Stereophile show. When I took the step into multichannel and found that ...
