Tandem configurations of two self-propelled flexible flappers finite span are explored by means numerical simulations. The same sinusoidal vertical motion is imposed on the leading edge both flappers, but with a phase shift ( $\phi$ ). In addition, offset, $H$ , prescribed between flappers. that emerge characterized in terms their hydrodynamic performance and topology. reach stable configuratio...

In this paper a new leader-follower formation of nonholonomic mobile robots is studied. The follower is a car-like vehicle and the leader is a tractor pulling a trailer. The leader moves along assigned trajectories and the follower is to maintain a desired distance and orientation to the trailer. A sliding mode control scheme is proposed for asymptotically stabilizing the vehicles to a time-var...

The multi-leader-follower game can be looked on as a generalization of the Nash equilibrium problem and the Stackelberg game, which contains several leaders and a number of followers. Recently, the multi-leader-follower game has been drawing more and more attention, for example, in electricity power markets. However, when we formulate a general multi-leader-follower game as a single-level game,...

Using a traditional leader-follower decisional sequence as the manifestation of power structure in a supply chain, this work generalizes extant research in IT security. We propose a game theoretic model to analyze the equilibrium IT security of the supply chain in the Stackelberg game, where the power structure in the supply chain manifests in a natural leader. Our results indicate that a natur...

This paper presents a formated navigation based on the leader-follower approach. In this approach, the control law of the follower robot includes the states of the leader robot. This is a drawback for implementing the control laws on real mobile robots. To overcome this drawback, this paper proposes a new follower’s control law, called the self-made follower input, in which the state of the lea...

Animals within groups need to coordinate their reactions to perceived environmental features and to each other in order to safely move from one point to another. This paper extends our previously published work on the flight patterns of Myotis velifer that have been observed in a habitat near Johnson City, Texas. Each evening, these bats emerge from a cave in sequences of small groups that typi...

As robotic platforms and unmanned aerial vehicles (UAVs) increase in sophistication and complexity, the ability to determine the spatial orientation and placement of the platform in real time (localization) becomes an important issue. Detecting and extracting locations of objects, barriers, and openings is required to ensure the overall effectiveness of the device. Current methods to achieve lo...

A field study of 84 registered nurses and their supervisors revealed that leaders' perceptions of leader-follower attitudinal similarity and follower extraversion were positively related to the quality of leader-follower exchanges. Neither followers' locus of control nor growth need strength was found to be significantly correlated with the quality of the exchange between leaders and followers.

Local health department directors' intent on getting their organizations ready for accreditation must embrace the blurring of leader/follower lines and create an accreditation readiness team fueled not by traditional leader or follower roles but by teamship.

Particularly socially influential individuals are present in many groups [1-8], but it is unclear whether their emergence is determined by their social influence versus the social susceptibility of others [9]. The social spider Stegodyphus dumicola shows regional variation in apparent leader-follower dynamics. We use this variation to evaluate the relative contributions of leader social influen...
