In this paper, a nonlocal foundation model is proposed to analyze the vibration and instability of a Y-shaped single-walled carbon nanotube (Y-SWCNT) conveying fluid. In order to achieve more accurate results, fourth order beam theory is utilized to obtain strain-displacement relations. For the first time, a nonlocal model is presented based on nonlocal elasticity and the effects of nonlocal fo...

The Laplace transform technique with respect ...

Hardy’s non-locality theorem for multiple two-level systems is explored in the context of generalized nonlocal theory. We find nonlocal but non-signaling probabilities, providing Hardy’s nonlocal argument, which are higher than those in Quantum Mechanics. Maximum probability of success of Hardy’s argument is obtained for three two-level systems in quantum as well as in a more generalized theory...
