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...

For a duopoly environment, we model the leader and follower real value functions assuming that the leader’s “market share” evolves according to an immigration (birth) and death process. We derive analytical solutions for the follower and leader options to invest, and numerical solutions for the leader’s optimal investment timing. Then we calculate the partial derivatives of the leader and follo...

Accurate maintenance of a geometric configuration between multiple autonomous vehicles can often accomplish objectives impossible for a single vehicle. Much work on formation control in the current literature relies on the leader-follower approach, where some vehicles are designated as leaders while others are designated as followers. The leaders track predefined trajectories, and the followers...

This paper introduces the notion of manipulability to mobile, multi-agent networks as a tool to analyze the instantaneous effectiveness of injecting control inputs at certain, so-called leader nodes in the network. Effectiveness is interpreted to characterize how the movements of the leader nodes translate into responses among the remaining follower nodes. This notion of effectiveness is a func...

Abstract: In order to explore the rendezvous problems of leader-follower multi-agent system further, three different kinds of strategies, namely the democracy strategy, the autarchy strategy as well as the mixed strategy, which were inspired by the mankind sys...

This paper addresses schemes for fault detection and isolation in a semi-decentralized environment. Now-a-days, sensor fault and failure are prevalent issues in numerous wireless sensor networks. We propose a few algorithms based on simple phenomenon of data fusion. Initially, a mutual consensus has been built among followers (e.g., Unmanned Autonomous Vehicles in this case) who are tracking a ...

Introduction F ORMATION flight of multiple aircraft has been an active research topic for many years. For the classical lead–follower configuration, when the follower is properly positioned with respect to the lead, the drag on the follower aircraft can be remarkably reduced due to strong wingtip vortices generated by the lead aircraft. Such close-formation flight configurations can lead to red...

Abstract This paper studies the simultaneous effects of relocation production (as part globalization) and institutions on intra- inter-country wage inequality. Firstly, empirical evidence shows that labor unions act at decreasing inequality, but this shrinking effect tends to be mitigated by globalization. Theoretically, we study conditions under which is verified. Unskilled labor-intensive rel...

Benevolent leadership, a traditional Chinese leadership style generated under the influence of Confucianism, has been under growing discussion since its proposal. However, existing research has focused mainly on the consequences of benevolent leadership, and research probing into its antecedents is scarce. To fill such research gap, the current study aims to explore the effect of the congruence...

Although it is challenging to implement follower forces in macroscale laboratory experiments, they can be implemented fairly easily in MEMS devices. This paper discusses the implementation of follower and axial end forces in a beam-type MEMS resonator for the application of resonant frequency tuning. r 2005 Elsevier Ltd. All rights reserved.
