Inverse problems occur in many scientific fields. Albeit grid search, where points of a regular grid are tested as possible solutions, is a straightforward and robust method to numerically solve inverse problems, it is computationally intensive and b

SUMMARYExhaustive searches in regular grids is a traditional and effective method for inversion, that is numerical solution of systems of non-linear equations which cannot be solved using formal algebraic techniques. However, this technique is effect

We investigate the robustness of chimera states under the influence of a nonlinear coupling in the form of a power law with exponent α. Taking as working example the Leaky Integrate-and-Fire model coupled in a 1D ring geometry, we show that the chim

The real time response of actors to events occurring in a network area is of critical importance in Wireless Sensor and Actor Networks (WSANs). This in turn requires fast notification of actors from Sensor Nodes (SNs) about events as well as effectiv

We design a dual-band THz absorber by combining a double split-ring metallic resonator with a graphene sheet sandwiched between two polymer spacers. An analytical model based on multiple interference theory is employed in order to analyze the absorpt
