Within-Session Variability Modelling for Factor Analysis Speaker Verification
This work presents an extended Joint Factor Analysis model including explicit modelling of unwanted within-session variability.

Deductive Formation of Recursive Workflows
We present an action theory with the power to represent recursive plans and the capability to reason about and synthesize recursive workflow control structures.
-
Action Exemplar Based Real-Time Action Detection
We propose a real-time action detection system based on a novel action representation and an effective learning method with a small training set. We represent actions with a new feature…

Document Logic: Risk Analysis of Business Processes Through Document Authenticity
Document Logic is a simple yet powerful framework to infer risks in business processes.

Effect of Various Coal Contaminants on the Performance of Solid Oxide Fuel Cells: Part I. Accelerated Testing
The contaminants that are potentially present in the coal-derived gas stream and their thermochemical nature are discussed.

Frontostriatal Fiber Bundle Compromise in HIV Infection Without Dementia
Quantitative fiber tracking derived from diffusion tensor imaging (DTI) was used to determine whether white matter association, projection, or commissural tracts are affected in nondemented individuals with HIV infection and to identify…

Test-Retest Reliability of Web-Based Retrospective Self-Report of Tobacco Exposure and Risk
The goal of this study was to examine the reliability of self-report of a specific health-affecting behavior, tobacco use, and its associated risk and protective factors as examined with a…

Effect of Various Coal Contaminants on the Performance of Solid Oxide Fuel Cells: Part II. Ppm and Sub-Ppm Level Testing
The poisoning effects of various trace contaminants in the coal-derived syngas stream at ppm and sub-ppm level on the performance of Ni-YSZ/YSZ/LSM solid oxide fuel cells were studied at extended…

Cavity Expansion Experiments with Spherical Explosive Charges in Concrete
Three experiments were conducted with 1-lb explosive spheres embedded in large concrete cylinders with flatpack stress gages and Dremin loop velocity gages surrounding the charge.

From 3D space to third place: the social life of small virtual spaces
Through our virtual ethnography of dance clubs and corner bars in three MMO environments, we find four features of virtual public spaces that appear critical for their success: accessibility, social…

Spectrum fusion: using multiple mass spectra for de novo peptide sequencing
We report on a new algorithm for combining the information from several mass spectra of the same peptide.

Natural and implicit interaction systems
The notion that humans move purposefully to obtain information provides a guiding framework to interpret natural body movements and gestures as implicit cues.
