Determination of the theoretical stress concentration factor in structural flat plates with two holes subjected to bending loads
(Contemporary Engineering SciencesBulgaria, 2018-11-22)
Numerous research works have studied the stress distribution in sections with
geometric discontinuities and the relationship with the theoretical factor of stress
concentration using the finite element method. These works ...

Black holes in Einstein–Gauss–Bonnet gravity with a string cloud background
(Elsevier Science, 2010-05)
We obtain a black hole solution in the Einstein–Gauss–Bonnet theory for the string cloud model in a five-dimensional spacetime. We analyze the event horizons and naked singularities. Later, we compute the Hawking temperature ...
Three-state model with competing antiferromagnetic and pairing interactions
(American Physical Society, 2019-04-24)
Motivated by the rich phase diagram of the high-temperature superconductors, we introduce a pseudospin model with three state variables which can be interpreted as two states (spin ±1/2) particles and holes. The Hamiltonian ...

Impedance spectroscopy study of solid-state dye-sensitized solar cells with varying Spiro-OMeTAD concentration
(2010-12-01)
This work reports on the changes of performance of solid-state cells dye-sensitized solar cells with the variation of concentration of spiro-OMeTAD between 5% and 25% in the fabrication of the cell. Variations of charge ...
Ab initio study on the role of the crystalline symmetry in the stabilization of the magnetic order in Al-doped SnS
(Elsevier Science, 2019-04)
We use firstprinciples calculations to study the electronic and magneticproperties of undoped and Al-doped SnS and their dependence withspace-group symmetry. The formation of a magnetic moment due to animpurity element was ...
