Firms spend high sums trying to make their “home” page as memorable as possible to attract repeat visits. For this purpose, fancy pictures and words are used to catch the atte...
We study here the spectra of random lifts of graphs. Let G be a finite connected graph, and let the infinite tree T be its universal cover space. If λ1 and ρ are the spectral ...
We propose a discrete variant of the Bak-Sneppen model for self-organized criticality. In this process, a configuration is an n-bit word, and at each step one chooses a random bit...
Abstract. We say the endomorphism problem is solvable for an element W in a free group F if it can be decided effectively whether, given U in F , there is an endomorphism φ of F ...
: The Jacobian matrix of a robot manipulator is central to the analysis, kinematics, dynamics, and control of robot manipulators. In many instances, the Jacobian and its inverse or...
