A prototype Malayalam to Sign Language Automatic Translator
Jestin Joy, Kannan Balakrishnan
Sign language, which is a medium of communication for deaf people, uses manual communication and body language to convey meaning, as opposed to using sound. This paper presents a p…
Bulk viscous matter and recent acceleration of the Universe
Athira Sasidharan, Titus K. Mathew
We consider a cosmological model dominated by bulk viscous matter with total bulk viscosity coefficient proportional to the velocity and acceleration of the expansion of the univer…
Scalar and Electromagnetic Quasinormal modes of Extended black hole in F(R) gravity
Saneesh Sebastian, V. C. Kuriakose
In this paper we study the scalar and electromagnetic perturbations of an extended black hole in F(R) gravity. The quasinormal modes in two cases are evaluated and studied their be…
A unified thermodynamic picture of Hořava-Lifshitz black hole in arbitrary space time
Jishnu Suresh, Tharanath R, V C Kuriakose
In this paper, we analyze the complete thermodynamic and phase transition phenomena of a black hole solution in Hořava-Lifshitz gravity in arbitrary space time. Nature of phase tra…
Late-time evolution of Dirac field around Schwarzschild-quintessence black hole
Nijo Varghese, V. C. Kuriakose
The late-time evolution of Dirac field around spherically symmetric black hole surrounded by quintessece is studied numerically. Our results show, for lower values of the quintesse…
Phase transitions and Geometrothermodynamics of Regular black holes
R. Tharanath, Jishnu Suresh, V. C. Kuriakose
In this paper we study the thermodynamics and state space geometry of regular black hole solutions such as Bardeen black hole, Ayón-Beato and García black hole, Hayward black hole…
Cosmology and thermodynamics of FRW universe with bulk viscous stiff fluid
Titus K Mathew, Aswathy M B, Manoj M
We consider a cosmological model dominated by stiff fluid with a constant bulk viscosity. We classify all the possible cases of the universe predicted by the model and analyzing th…
Quasinormal Modes of Lovelock Black Holes
C. B. Prasobh, V. C. Kuriakose
The quasinormal modes of metric perturbations in asymptotically flat black hole spacetimes in the Lovelock model are calculated for different spacetime dimensions and higher orders…
Thermodynamic Geometry of Reissener-Nordström-de Sitter black hole and its extremal case
R. Tharanath, Jishnu Suresh, Nijo Varghese +1
We study the thermodynamics and the different thermodynamic geometric methods of Reissener-Nordström-de Sitter black hole and its extremal case, which is similar to the de Sitter b…
Phase transition, Quasinormal modes and Hawking radiation of Schwarzschild black hole in Quintessence field
R. Tharanath, Nijo Varghese, V C Kuriakose
Black hole thermodynamic stability can be determined by studying the nature of heat capacity of the system. For Schwarzschild black hole the heat capacity is negative, but in the q…
Thermodynamics and Thermodynamic geometry of Park black hole
Jishnu Suresh, Tharanath R, Nijo Varghese +1
We study the thermodynamics and thermodynamic geometry of Park black hole in Hořava gravity. By incorporating the ideas of differential geometry, we have investigated the thermodyn…
Betweenness Centrality in Some Classes of Graphs
Sunil Kumar R, Kannan Balakrishnan, M. Jathavedan
There are several centrality measures that have been introduced and studied for real world networks. They account for the different vertex characteristics that permit them to be ra…
Morphological filtering on hypergraphs
V. Bino Sebastian, A Unnikrishnan, Kannan Balakrishnan +1
The focus of this article is to develop computationally efficient mathematical morphology operators on hypergraphs. To this aim we consider lattice structures on hypergraphs on whi…
Dirac Quasinormal modes of MSW black holes
Saneesh Sebastian, V. C. Kuriakose
In this paper we study the Dirac quasinormal modes of an uncharged 2 + 1 black hole proposed by Mandal et. al and referred to as MSW black hole in this work. The quasi- normal mode…
Scattering of Scalar Field by an Extended Black Hole in F(R) gravity
Saneesh Sebastian, V. C. Kuriakose
In this work we have studied the scattering of scalar field around an extended black hole in F(R) gravity using WKB method. We have obtained the wave function in different regions…
