We solve the full-consensus problem (in position and orientation) with connectivity maintenance for multiple nonholonomic vehicles in a leader-follower configuration. rely on polar-coordinates based model which is more natural setting. The proposed control law smooth domain of definition) time-invariant uses only relative measurements, making it suited implementation. establish asymptotic conve...

Using tools from algebraic graph theory and nonsmooth analysis in combination with ideas of collective potential functions, velocity consensus and navigation feedback, a distributed leader–follower flocking algorithm formulti-agent dynamical systemswith time-varying velocities is developedwhere each agent is governed by second-order dynamics. The distributed leader–follower algorithm considers ...

This study tests the similarity attraction paradigm using a measure of work motivation and leader-member exchanges. Seventy-five elected officials were sampled along with 368 of their staffers. Results indicate actual self-reported differences in sources of work motivation were not predictive of leader-follower exchanges, which is counter to the similarity attraction paradigm. It is argued that...

This papers looks at moving a group of mobile robots in formation via a virtual leader-follower scheme. A novel way of introducing feedback from followers to a virtual leader is presented. Hardware results are presented for Hilare-type mobile robots.

In this paper, we investigate the synchronization phenomenon between two Spin-transfer Torque Nanooscillators (STNOs) of different frequencies in pillar systems under vortex configuration detunings or driving frequencies. The oscillators’ mutual occurs through magnetic dipolar interaction. Our micromagnetic simulations show that an amplitude fluctuation referred to as [Formula: see text] has a ...

Abstract Limited by rigid instruments, traditional open curettage of bone cysts requires large incisions and the removal substantial amounts healthy tissue to approach lesion. This causes a lengthy recovery period with an increased risk for complications. While other less invasive methods have been suggested, none accepted as standard treatment modalities, many them not applied beyond academic ...

This paper concerns the problem of consensus tracking for multiagent systems with a dynamical leader. In particular, it proposes the corresponding explicit control laws for multiple first-order nonlinear systems, second-order nonlinear systems, and quite general nonlinear systems based on the leader-follower and the tree shaped network topologies. Several numerical simulations are given to veri...

The third generation technology will confer to mobile phones all the capacity and speed of a fixed line phone with the additional flexibility of mobility. Major investments in 3G installation facilities are planned in developed economies; the reported investment plans indicate “leader-follower” patterns. Using three real competition options models, we determine the optimal timing of 3G investme...

In this work, we study a leader-follower consensus protocol where both leaders and followers negotiate their states over a stochastically-switching network. The model incorporates the phenomenon of numerosity, which limits the perception of exact numbers. We derive a closed form expression for the asymptotic convergence factor that provides a necessary and sufficient condition for convergence a...

The problem of computing the strategy to commit to has been widely investigated in the scientific literature for the case where a single follower is present. In the multi-follower setting though, results are only sporadic. In this paper, we address the multi-follower case for normal-form games, assuming that, after observing the leader’s commitment, the followers play pure strategies and reach ...
