This paper considers theoretical analysis of recovering a low rank matrix given few expansion coefficients with respect to any basis. The current approach generalizes the existing for low-rank completion problem sampling under entry sensing or symmetric orthonormal is based on dual certificates using basis approach. We introduce condition called correlation condition. can be computed in time O ...

Conventional electronic processors, which are the mainstream and almost invincible hardware for computation, approaching their limits in both computational power energy efficiency, especially large-scale matrix computation. By combining electronic, photonic, optoelectronic devices circuits together, silicon-based computation has been demonstrating great capabilities feasibilities. Matrix is one...

the matrix functions appear in several applications in engineering and sciences. the computation of these functions almost involved complicated theory. thus, improving the concept theoretically seems unavoidable to obtain some new relations and algorithms for evaluating these functions. the aim of this paper is proposing some new reciprocal for the function of block anti diagonal matrices. more...

Fullerene is a cage-like carbon allotrope admitting vast range of applications. Some the important fullerenes are C54,C58,C60,C70,C74,C76,C78,C80C82,C84,C86,C90. The physical properties can be exhibited using degree-based topological indices. sum based geometric arithmetic index significant in this manner. atomic bond connectivity, Randic, first and second Zagreb indices well known We have dete...

Introduction: The aim of this study was to evaluate the effect of proximal contour of class II composite restorations placed with straight or contoured matrix band using composite resins with different modulus of elasticity on stress distribution by finite element method. Methods: In order to evaluate the stress distribution of class II composite restorations using finite element method, upper ...
