DOI: 10.1007/s00521-019-04028-9
Abstract: We present the Resilient Self-organizing Tissue (ReST) model, a self-organized neural model based on an infinitely often continuously differentiable ($$C^\infty$$C∞) energy function. ReST extends older work on energy-based self-organizing models (IEEE international conference on neural… read more here.

DOI: 10.1016/j.compstruct.2016.10.114
Abstract: Predicting the effective thermo-mechanical response of heterogeneous materials such as composites, using virtual testing techniques, requires imposing periodic boundary conditions on geometric domains. However, classic methods of imposing periodic boundary conditions require identical finite element… read more here.
