The Contribution of Cepstral and Stylistic Features to SRI’s 2005 NIST Speaker Recognition Evaluation System
Recent work in speaker recognition has demonstrated the advantage of modeling stylistic features in addition to traditional cepstral features, but to date there has been little study of the relative contributions of these different feature types to a state-of-the-art system. In this paper we provide such an analysis, based on SRI’s submission to the NIST…

Compositionality for Tightly Coupled Systems: a New Application of the Propositions-As-Types Interpretation
Although compositional techniques are being successfully employed in practice, the use of such techniques is often rather informal and intuitive, and typically a justification for correct behaviour of the composed system exists but is not expressed explicitly. In this paper, we show what can be gained from treating such justifications as first-class citizens.

Measuring Middle School Teachers’ Mathematical Knowledge Of Teaching Rate And Proportionality
We are investigating if teachers from across the state of Texas can use a specially designed replacement unit and SimCalc software to help their students learn mathematics important to the Texas state frameworks, as well as content that goes beyond the state framework—the beginning pieces of the “mathematics of change,” leading to Calculus.
