Degeneracy in transportation problems [PDF]

open access: yes, 1986
This paper presents a systematic study of the effects of degeneracy on a primal simplex algorithm as implemented in GNET. The relationship between the degeneracy and the geometry of a transportation polytope is discussed and some new results are provided.

Cosmographic degeneracy

open access: yesPhysical Review D, 2011
We examine the dark energy and matter densities allowed by precision measurements of distances out to various redshifts, in the presence of spatial curvature and (near) arbitrary behavior of the dark energy equation of state. Degeneracies among the parameters permit a remarkably large variation in their values when using only distance measurements of ...

Weak degeneracy of graphs [PDF]

open access: yes, 2022
Motivated by the study of greedy algorithms for graph coloring, we introduce a new graph parameter, which we call weak degeneracy. By definition, every $d$-degenerate graph is also weakly $d$-degenerate. On the other hand, if $G$ is weakly $d$-degenerate,

Simultaneous Dirac-like Cones at Two Energy States in Tunable Phononic Crystals: An Analytical and Numerical Study

open access: yesCrystals, 2021
Simultaneous occurrence of Dirac-like cones at the center of the Brillouin zone (Γ) at two different energy states is termed Dual-Dirac-like cones (DDC) in this article. The occurrence of DDC is a rare phenomenon.

Detection and Compensation of Degeneracy Cases for IMU-Kinect Integrated Continuous SLAM with Plane Features

open access: yesSensors, 2018
In a group of general geometric primitives, plane-based features are widely used for indoor localization because of their robustness against noises. However, a lack of linearly independent planes may lead to a non-trivial estimation.

The Woodlanders : pur darwinisme ou ‘evolutionary meliorism’ ?

open access: yesMiranda: Revue Pluridisciplinaire du Monde Anglophone, 2010
Thomas Hardy was deeply influenced by his discovery of The Origin of Species when he was nineteen and his dark, favourite novel The Woodlanders, with its intricate web of woods and entwined destinies, is steeped in Darwinian metaphors connoting the ...

Extending the permissible control loop latency for the controlled inverted pendulum [PDF]

open access: yes, 2004
A pendulum can be stabilized in its upright position by proportional-plus-derivative (PD) feedback control only if the latency in the control loop is smaller than a certain critical delay.

Ion‐channel degeneracy: Multiple ion channels heterogeneously regulate intrinsic physiology of rat hippocampal granule cells

open access: yesPhysiological Reports, 2021
Degeneracy, the ability of multiple structural components to elicit the same characteristic functional properties, constitutes an elegant mechanism for achieving biological robustness.
