Evolutionary Mahalanobis Distance-Based Oversampling for Multi-Class Imbalanced Data Classification
Sensors, 2021 The number of sensing data are often imbalanced across data classes, for which oversampling on the minority class is an effective remedy. In this paper, an effective oversampling method called evolutionary Mahalanobis distance oversampling (EMDO) is ...

The size and shape of the oblong dwarf planet Haumea [PDF]
, 2014 We use thermal radiometry and visible photometry to constrain the size, shape, and albedo of the large Kuiper belt object Haumea. The correlation between the visible and thermal photometry demonstrates that Haumea's high amplitude and quickly varying ...

Reduction of geodetic observations to the reference ellipsoid
Vojnotehnički Glasnik, 2011 Field observations refer to the vertical of the geoid, because the geodetic instruments are put in the working position in respect to the vertical. It is not appropriate for the calculations on the ellipsoid surface, which request measured elements to be

Scalable Ellipsoidal Classification for Bipartite Quantum States [PDF]
, 2008 The Separability Problem is approached from the perspective of Ellipsoidal Classification. A Density Operator of dimension N can be represented as a vector in a real vector space of dimension $N^{2}- 1$, whose components are the projections of the matrix

A variational problem on Stiefel manifolds [PDF]
, 2006 In their paper on discrete analogues of some classical systems such as the rigid body and the geodesic flow on an ellipsoid, Moser and Veselov introduced their analysis in the general context of flows on Stiefel manifolds.

Structure model index does not measure rods and plates in trabecular bone
Frontiers in Endocrinology, 2015 Structure model index (SMI) is widely used to measure rods and plates in trabecular bone. It exploits the change in surface curvature that occurs as a structure varies from spherical (SMI = 4), to cylindrical (SMI = 3) to planar (SMI = 0).

Mathematics, 2023 The gravity force of a gravity field generated by a non-rotating level ellipsoid of revolution enclosing mass M is given as a solution of a partial differential equation along with a boundary condition of Dirichlet type. The partial differential equation

Ellipsoidal Collapse and Previrialization [PDF]
The Astronomical Journal, 2001 We study the non-linear evolution of a dust ellipsoid,embedded in a Friedmann flat background universe, in order to determine the evolution of the density of the ellipsoid as the perturbation to it related detaches from general expansion and begins to collapse.
