The introduction of the displacements of nodal points of a structural system as unknowns in the displacement method yields matrix equations of a very great size. The various methods recently introduced in reducing the number of unknowns are discussed in this paper with special reference to ...
Incremental unknowns and graph techniques with in-depth refinement Summary: The condition number of the incremental unknowns matrix associated to the Laplace operator is $O(1/h^2_0) O((\\log h)^2)$, where $h_0$ is the mesh... F Tone - 《International Journal of Numerical Analysis &...
Using a generic normal form, we demonstrate that the unstable periodic orbit generated by a subcritical Hopf bifurcation, which has a single real unstable Floquet multiplier, can in fact be stabilized. We derive explicit analytical conditions for the control matrix in terms of the amplitude and ...

Estimation of the mixing matrix for underdetermined blind source separation using spectral estimation techniques Blind source separation is concerned with estimating n source signals from m measurements that are generated through an unknown mixing process. In the unde... L Vielva,I Santamaría,C Pantal...

(2018)). This model differs from tree models in that we do not estimate parameters such as splitting times which may or may not be meaningful or appropriate for various species (Scerri et al., 2019) depending on their actual (unknown) demographic history. We acknowledge the limitations of ...
Within the plethora of collective states a complex network can exhibit, we show that the phenomenon of Collective Almost Synchronisation (CAS), which describes a state with an infinite number of patterns emerging in complex networks for weak coupling strengths, deserves special attention. We show ...
where is a n×n fuzzy numbers matrix,the unknown vector X and the constant U are all n dimension vectors sonsisting of fuzzy numbers,and the addition and multiplication are defined by Zadeh's extension principle.Firstly we study the existential condition of solution,then discuss the iteration ...
then the contribution to the ground state energy due to the three-body correlations could become dominant and provide a self-trapping mechanism1. The second scenario corresponds to a condensed Bose–Bose mixture where the interspecies attraction becomes stronger than the geometrical average of the int...
