Most often, autonomous robots maintain group formations by using global information such as the position of the group leader or even the position of all robots inside the formation. Alternative approaches to autonomous robot formations have considered local information, which is more realistic but presents some drawbacks such as troop deformation. In this paper we perform a step forward in loca...

Even since pioneering work of Levine and Athans and Melzer and Kuo, control of vehicular formations has been a topic of active research. In spite of its apparent simplicity, this problem poses significant engineering challenges, and it has often inspired theoretical developments. In this article, we view vehicular formations as a particular instance of dynamical systems over networks and summar...

In this paper, a systematic way of maintaining rigidity in case of vehicle removals in formations for coordinating mobile autonomous vehicles with limited communication/sensing links is presented. The main concern is the minimal rearrangement of links in such a way that the links that have not been removed are preserved as they are, and the minimum number of new links are created in the formati...

We examine the effect of financial dependence on the acquisition and investment of singlesegment and conglomerate firms at different stages of the industry life cycle. Conglomerates and single-segment firms differ in acquisition activity more than in the level of capital expenditure across all stages. Financial dependence, a deficit in a segment’s internal financing, decreases the likelihood of...
