A Novel Method For Speech Segmentation Based On Speakers' Characteristics

, 2012
Speech Segmentation is the process change point detection for partitioning an input audio stream into regions each of which corresponds to only one audio source or one speaker. One application of this system is in Speaker Diarization systems.

High‐Sensitivity Terahertz Gas Sensing Enabled by Undercut Metal‐Dielectric‐Metal Metamaterial

Advanced Materials Interfaces, EarlyView.
A terahertz (THz) metamaterial gas sensor is demonstrated using a metal–dielectric–metal (MDM) absorber with an undercut dielectric layer, which enlarges the gas‐replaced volume and strengthens refractive‐index perturbation of the resonant mode. A reflection dip at 0.766 THz is observed, and acetone–nitrogen tests yield concentration‐dependent shifts ...

Automatic view schema generation in object-oriented databases [PDF]

, 1992
An object-oriented data schema is a complex structure of classes interrelated via generalization and property decomposition relationships. We define an object-oriented view to be a virtual schema graph with possibly restructured generalization and ...

Two Dimensional Clustering of Gamma-Ray Bursts using durations and hardness

, 2017
Gamma-Ray Bursts (GRBs) have been conventionally bifurcated into two distinct categories: ``short'' and ``long'' with durations less than and greater than two seconds respectively. However, there is a lot of literature (although with conflicting results)

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Multiphase oxidation of SO₂ by NO₂ on CaCO₃ particles [PDF]

Atmospheric Chemistry and Physics, 2018
Heterogeneous/multiphase oxidation of SO2 by NO2 on solid or aqueous particles is thought to be a potentially important source of sulfate in the atmosphere, for example, during heavily polluted episodes (haze), but the reaction mechanism and rate are ...

Tailoring Electric and Magnetic Dipole Emission of Er3+ Ions via Toroidal Dipole Resonance of Si Nanodisk Hexagonal Array

Advanced Optical Materials, EarlyView.
Hexagonal arrays of silicon nanodisks are proposed to control 1.5 µm emission of Er3+ ions. Toroidal dipole resonance of the nanodisk array generates accessible magnetic hot spots at the surface, leading to enhanced and highly directional magnetic dipole emission along the surface‐normal direction via the magnetic Purcell effect.

The role of meteorological conditions and pollution control strategies in reducing air pollution in Beijing during APEC 2014 and Victory Parade 2015 [PDF]

Atmospheric Chemistry and Physics, 2017
To control severe air pollution in China, comprehensive pollution control strategies have been implemented throughout the country in recent years. To evaluate the effectiveness of these strategies, the influence of meteorological conditions on levels ...

Efficient recursion termination for function-free horn logic [PDF]

, 1986
We present an efficient scheme to terminate infinite recursion in function-free Horn logic. In [BW84], Brough and Walker show that a preorder linear resolution with a goal termination strategy is incomplete, i.e. it must miss some answers.

Robotic Control for Human–Robot Collaborative Assembly Based on Digital Human Model and Reinforcement Learning

Advanced Robotics Research, EarlyView.
This work presents a robotic control method for human–robot collaborative assembly based on a biomechanics‐constrained digital human model. Reinforcement learning is used to generate physiologically plausible human motion trajectories, which are integrated into a virtual environment for robot control learning.
