A Decision-Tree-Based Algorithm for Speech/Music Classification and Segmentation

open access: yesEURASIP Journal on Audio, Speech, and Music Processing, 2009
We present an efficient algorithm for segmentation of audio signals into speech or music. The central motivation to our study is consumer audio applications, where various real-time enhancements are often applied.

Nonparametric IV estimation of shape-invariant Engel curves [PDF]

open access: yes, 2003
This paper concerns the identification and estimation of a shape-invariant Engel curve system with endogenous total expenditure. The shape-invariant specification involves a common shift parameter for each demographic group in a pooled system of Engel

A Spheroid Model for the Role of Shape in Particle Size Analysis

open access: yesKONA Powder and Particle Journal, 2015
Standard procedure in particle size analysis is to express size as an equivalent sphere diameter. As a consequence, results obtained by procedures based on different kinds of response give different results.

The inverse sieve problem in high dimensions [PDF]

open access: yes, 2011
We show that if a big set of integer points in [0,N]^d, d>1, occupies few residue classes mod p for many primes p, then it must essentially lie in the solution set of some polynomial equation of low degree.

Faster tuple lattice sieving using spherical locality-sensitive filters [PDF]

open access: yes, 2017
To overcome the large memory requirement of classical lattice sieving algorithms for solving hard lattice problems, Bai-Laarhoven-Stehl\'{e} [ANTS 2016] studied tuple lattice sieving, where tuples instead of pairs of lattice vectors are combined to form ...

Effect of nanoclay particles on some physical and mechanical properties of soils [PDF]

open access: yesJournal of Agricultural Machinery, 2016
Introduction: As a mechanical tillage practices on soil preparation improve soil structure, increase in porosity, better distribution of soil aggregates and eventually modify the physical properties of soil.

New image analysis of large food particles can discriminate experimentally suppressed mastication [PDF]

open access: yes, 2012
Objective parameters that could provide a basis for food texture selection for elderly or dysphagic patients have not been established. We, therefore, aimed to develop a precise method of measuring large particles (>2 mm in diameter) in a bolus and an ...

Six-Dimensional Pose Estimation of Molecular Sieve Drying Package Based on Red Green Blue–Depth Camera

open access: yesSensors
This paper aims to address the challenge of precise robotic grasping of molecular sieve drying bags during automated packaging by proposing a six-dimensional (6D) pose estimation method based on an red green blue-depth (RGB-D) camera. The method consists

Levels of Distribution and the Affine Sieve

open access: yes, 2014
This article is an expanded version of the author's lecture in the Basic Notions Seminar at Harvard, September 2013. Our goal is a brief and introductory exposition of aspects of two topics in sieve theory which have received attention recently: (1) the ...

First-principles prediction of magnetically ordered half-metals above room temperature

open access: yesJournal of Materiomics, 2019
Half-metallicity (HM) offers great potential for engineering spintronic applications, yet only few magnetic materials present metallicity in just one spin channel.
