Sedentary Sphere: Wrist-Worn Accelerometer-Brand Independent Posture Classification
GENEACTIV ACTIGRAPH ACTIVPAL SITTING TRIAXIAL
2017/4/13
Introduction: Access to raw acceleration data should facilitate comparisons between accelerometer outputs regardless of monitor brand.
Purpose: To evaluate the accuracy of posture classification usin...
Private Moralities in the Public Sphere:Democratization,Islam,and Gender in Indonesia
Islam democratization gender Indonesia morality
2016/1/26
Over the past two decades, Indonesia has been transformed socially and politically by two major movements: the Islamic movement and the democratization movement. One point of convergence between these...
Numerically simulating impact disruptions of cohesive glass bead agglomerates using the soft-sphere discrete element method
Asteroids, Surfaces Collisional physics Geological processes Regoliths
2015/12/25
We present our implementation of cohesion in the parallel N-body code pkdgrav in order to model small bodies that are not fully monolithic but that have at least some degree of cohesion. Small bodies ...

2015/12/25
We present our implementation of the soft-sphere discrete element method (SSDEM) in the parallel gravitational N-body code pkdgrav, a well-tested simulation package that has been used to provide many ...
Numerical simulations of granular dynamics:I. Hard-sphere discrete element method and tests
Asteroids, Surfaces Collisional physics Geological processes Regoliths
2015/12/25
We present a new particle-based (discrete element) numerical method for the simulation of granular dynamics, with application to motions of particles on small solar system body and planetary surfaces....

Robust Algorithm for Fitting Sphere to 3D Point Clouds in Terrestrial Laser Scanning
Laser scanning Fitting Terrestrial photogrammetry
2015/12/16
Sphere target is one of the most important tools in terrestrial laser scanning. Different point clouds obtained form different views can
be transformed into the same coordinate system frame by using ...
REPRESENTATION OF GRADIENTS OF A SCALAR FIELD ON THE SPHERE USING A 2D FOURIER EXPRESSION
2D Fourier series gradients representation coefficients D-functions spectral transfers
2016/1/18
Representation of data on the sphere is conventionally done using spherical harmonics. Making use of the Fourier series of the Legendre function in the SH representation results in a 2D Fourier expres...
Robust and Automatic Vanishing Points Detection with Their Uncertainties from a Single Uncalibrated Image, by Planes Extraction on the Unit Sphere
Photogrammetry Geometry Vanishing points extraction Image Orientation Error estimation
2015/12/4
This paper deals with the retrieval of vanishing points in uncalibrated images. Many authors did work on that subject in the computer vision field because the vanishing point represents a major inform...

ON SIMULTANEOUS LINEARIZATION OF DIFFEOMORPHISMS OF THE SPHERE
DIFFEOMORPHISMS SIMULTANEOUS LINEARIZATION
2015/9/29
Let R1, R2 . . . Rm be rotations generating SOd+1, d ≥
2, and f1, f2 . . . fm be their small smooth perturbations. We show
that {fα} can be simultaneously linearized if and only if the assocated ran...

Symmetric quadrature rules for simplexes based on sphere close packed lattice arrangements
Quadrature Integration Symmetric Triangle
2015/7/3
There have been significant efforts to identify high-order quadrature rules on d-simplex and d-hypercube geometries as evidenced by the surveys in [1–5]. On thed-hypercube, it is well-known that optim...
