Patterns of event propagation in online social networks provide novel insights on the modeling and analysis of information dissemination over networks and physical systems. This paper studies the importance of follower links for event propagation on Twitter. Three recent event propagation traces are collected with the user languages being used to identify the Network of Networks (NoN) structure...

The paper briefly presents the dynamic synthesis of mechanisms with superior couplings, force, and speed distribution, efficiency, loss coefficient, coefficient or motion transmission function, determination variable angular input from crank cam based on solving equation Lagrange, variation follower (adept) integration Newton’s equation, analysis several models taken into account. In end, origi...

The joints between segmental rings can withstand a certain amount of bending moment as well as axial and shear forces. Generally, in the structural analysis of tunnel segmental lining, the joints can be modeled as elastic hinges or rotational springs, and their rigidity should be demonstrated in terms of the rigidity of the joints or their rotational stiffness. Therefore, the bending moment act...

This study attempted to establish an optimal design and perform dynamic analysis for a spring-actuated cam-linkage composite mechanism in rated 12 kV, 25 kA vacuum circuit breaker (VCB). The of the VCB involves two steps: first step stiffness closing springs cam profile, based on three-order polynomial motion curve follower; second four-bar linkage. To minimize surplus work operating mechanism,...
