, 2007 We show that a generalised phantom Chaplygin gas can present a future singularity in a finite future cosmic time. Unlike the big rip singularity, this singularity happens for a finite scale factor, but like the big rip singularity, it would also take ...

On bulk singularities in the random normal matrix model [PDF]
, 2016 We extend the method of rescaled Ward identities of Ameur-Kang-Makarov to study the distribution of eigenvalues close to a bulk singularity, i.e. a point in the interior of the droplet where the density of the classical equilibrium measure vanishes.

Making Telehealth a Strategic Asset to Achieve Efficiency
Blockchain in Healthcare Today, 2021 Session Description: Efficiency is widely recognized as one of the most important concepts in economics and business, a generic definition from Knapp (1984) coins it as 'the allocation of scarce resources that maximizes the achievement of aims ...

Newtonian Analysis of Gravitational Waves from Naked Singularity [PDF]
, 2000 Spherical dust collapse generally forms a shell focusing naked singularity at the symmetric center. This naked singularity is massless. Further the Newtonian gravitational potential and speed of the dust fluid elements are everywhere much smaller than ...

Singularity property and singularity-free path planning of the Gough–Stewart parallel mechanism
International Journal of Advanced Robotic Systems, 2017 Singularity affects the performance of the parallel mechanisms seriously and so should be avoided as the mechanisms work. It is necessary to obtain the distribution of the singularity locus in the task space of a parallel mechanism and then further ...

Naked singularity resolution in cylindrical collapse
, 2006 In this paper, we study the gravitational collapse of null dust in the cylindrically symmetric spacetime. The naked singularity necessarily forms at the symmetry axis.

The Central Singularity in Spherical Collapse [PDF]
, 2000 The gravitational strength of the central singularity in spherically symmetric space-times is investigated. Necessary conditions for the singularity to be gravitationally weak are derived and it is shown that these are violated in a wide variety of ...

Naked singularity, firewall, and Hawking radiation
, 2017 Spacetime singularity has always been of interest since the proof of the Penrose-Hawking singularity theorem. Naked singularity naturally emerges from reasonable initial conditions in the collapsing process.
