Active earth thrust on walls supporting granular soils: Effect of wall movement
(IOS Press, 2013)The methods currently used in the design practice of retaining walls supporting granular soils (sand, gravel, silt, and their mixtures) assume that the soil friction angle and, consequently, the active earth pressure ...

Bilateral routing in emergency response networks
(IEEE Computer Society, 2013)An emergency response networking scenario is considered, in which immediately after the strike of a disaster, mobile terminals autonomously form an adhoc network. Distress nodes, use this network to disseminate helprequests ...

Change of θ dependence in 4D SU(N) gauge theories across the deconfinement transition
(2013)We study the dependence of 4D SU(N) gauge theories on the topological θ term at finite temperature T. We exploit the lattice formulation of the theory, presenting numerical results for the expansion of the free energy up ...

Computation of correlation matrices for tetraquark candidates with Jp = 0+ and flavor structure q1q2q3q3
(Proceedings of Science (PoS), 2015)The conjecture that several recently observed mesons have a structure, which is not dominated by an ordinary quarkAntiquark pair, but by a fourquark structure, is being actively investigated both theoretical and ...

Convergence analysis of an hp finite element method for singularly perturbed transmission problems in smooth domains
(2013)We consider a twodimensional singularly perturbed transmission problem with two different diffusion coefficients, in a domain with smooth (analytic) boundary. The solution will contain boundary layers only in the part of ...
