Black hole search and exploration in unoriented tori with synchronous scattered finite automata
(2012)We consider the problem of locating a black hole in a synchronous, anonymous, and unoriented torus network using mobile agents. A black hole is a harmful network node that destroys any agent visiting it without leaving any ... -
Black hole search with finite automata scattered in a synchronous torus
(2011)We consider the problem of locating a black hole in synchronous anonymous networks using finite state agents. A black hole is a harmful node in the network that destroys any agent visiting that node without leaving any ... -
Dangerous graphs
(2019)Anomalies and faults are inevitable in computer networks, today more than ever before. This is due to the large scale and dynamic nature of the networks used to process big data and to the ever-increasing number of ad-hoc ... -
Double chain-star: An RDF indexing scheme for fast processing of SPARQL joins
(2016)State of the art RDF stores often rely on exhaustive indexing and sequential (self-)joins for SPARQL query processing. However, query execution is dependent on, and often limited by the underlying storage and indexing ... -
Einstein and Møller Energy-Momentum Complexes for a New Regular Black Hole Solution with a Nonlinear Electrodynamics Source
(2016)A study about the energy and momentum distributions of a new charged regular black hole solution with a nonlinear electrodynamics source is presented. The energy and momentum are calculated using the Einstein and Møller ... -
Energy-Momentum for a Charged Nonsingular Black Hole Solution with a Nonlinear Mass Function
(2017)The energy-momentum of a new four-dimensional, charged, spherically symmetric, and nonsingular black hole solution constructed in the context of general relativity coupled to a theory of nonlinear electrodynamics is ... -
Localization of Energy-Momentum for a Black Hole Spacetime Geometry with Constant Topological Euler Density
(2018)The evaluation of the energy-momentum distribution for a new four-dimensional, spherically symmetric, static and charged black hole spacetime geometry with constant nonzero topological Euler density is performed by using ... -
Particle motion around charged black holes in generalized dilaton-axion gravity
(2018)The behaviour of massive and massless test particles around asymptotically flat and spherically symmetric, charged black holes in the context of generalized dilaton-axion gravity in four dimensions is studied. All the ... -
A Relativistic Compact Stellar Model of Anisotropic Quark Matter Mixed with Dark Energy
(2021)The possibility of strange stars mixed with dark energy to be one of the candidates for dark energy stars is the main issue of the present study. Our investigation shows that quark matter atcs as dark energy after a certain ... -
Tight bounds for scattered black hole search in a ring
(2011)We study the problem of locating a particularly dangerous node, the so-called black hole in a synchronous anonymous ring network with mobile agents. A black hole destroys all mobile agents visiting that node without leaving ...
