Speaker Adaptation of Language and Prosodic Models for Automatic Dialog Act Segmentation of Speech
This study explores speaker-specific modeling for the task of automatic segmentation of speech into dialog acts (DAs), using a linear combination of speaker-dependent and speaker-independent language and prosodic models.

Daytime Sleepiness, Psychomotor Performance, Waking Eeg Spectra and Evoked Potentials in Women with Severe Premenstrual Syndrome
We assessed daytime sleepiness using objective and subjective measures in women with severe premenstrual syndrome (PMS) compared with women without significant premenstrual symptoms.

A comparison of approaches for modeling prosodic features in speaker recognition
In this work, we study the two modeling techniques for the simpler set of features. We show that, for these features, a combination of JFA systems for different sequence lengths…

Design of Short Linear Peptides That Show Hydrogen Bonding Constraints in Water
Using a combination of an aromatic amino acid, a homoserine side chain, and a d-amino acid, a series of linear tetrapeptides were designed that adopt an “Hse turn” in water.

Across-phone variability and diagonal term in joint factor analysis for speaker recognition
We investigate usefulness of across-phone variability for speaker recognition in a joint factor analysis (JFA) framework. We estimate the variability as across-phone covariance within a conversation side averaged over all…

Design Pattern On Model Use In Interdependence Among Living Systems (Large-Scale Assessment Technical Report 13)
The report outlines the key elements of the design pattern, describes the design pattern development process, and illustrates with examples how the design pattern supports storyboard and item design for…

Inclined Dislocation-Pair Relaxation Mechanism in Homoepitaxial Green GaInN/GaN Light-Emitting Diodes
The creation of symmetrical pairs of inclined dislocations was observed in the GaInN/GaN quantum wells (QWs) of c-axis grown green light-emitting diodes (LEDs) on low-defect density bulk GaN substrate, but not…

Meeting Student Challenges to Innovative Instruction with Improved Assessment Techniques
Presentation of an R&D project focused on the assessment of project-based learning involving community college instructors, and engagement in some of the reflection activities that helped instructors identify and measure…

Fast likelihood computation using hierarchical Gaussian shortlists
We investigate the use of hierarchical Gaussian shortlists to speed up Gaussian likelihood computation.

Indirect Validation of Tropospheric Nitrogen Dioxide Retrieved from the OMI Satellite Instrument: Insight Into the Seasonal Variation of Nitrogen Oxides at Northern Midlatitudes
We examine the seasonal variation in lower tropospheric nitrogen oxides at northern midlatitudes by evaluating tropospheric NO2 columns observed from the Ozone Monitoring Instrument.

The Damage Mechanism Route to Better Armor Materials
This paper describes the mechanisms by which brittle materials are penetrated by impacting projectiles, links ballistic performance to fracture behavior, and in turn to microstructure, and suggests a route unexplored…

Using Knowledge about How People Learn to Define Learning Goals
How well are college general education classes preparing students to apply big ideas to real-world problems? What are the major steps of domain-specific assessment design? Presented at Innovations 2010.
