this paper deals with leader-following and leaderless consensus problems of high-order multi-input/multi-output (mimo) multi-agent systems with unknown nonlinear dynamics in the presence of uncertain external disturbances. the agents may have different dynamics and communicate together under a directed graph. a distributed adaptive method is designed for both cases. the structures of the contro...

In a graph G, the distance d(u, v) between a pair of vertices u and v is the length of a shortest path joining them. The eccentricity e(u) of a vertex u is the distance to a vertex farthest from u. The minimum eccentricity is called the radius of the graph and the maximum eccentricity is called the diameter of the graph. The radial graph R(G) based on G has the vertex set as in G, two vertices ...

Automatic generation of distribution system diagrams is an important aid for the distribution system planner and operator alike for easy visualization of the system. Since a Radial distribution system has a tree structure, what we need to develop is essentially a tree drawing algorithm. In addition,we aim to generate a distribution system graph that is aesthetically pleasing. We define a new se...

There is a universal component to the semantics of reduplication, which can be expressed as a radial category of concepts. I present this radial category, along with supporting evidence from a range of languages, and motivations for the links between the various senses. The structure of the radial graph gives rise to a number of predicted implicational universals. I also show that the radial ca...

Graphs are widely and effectively used abstractions for organizing and visualizing information. In this paper we present a graph data structure for representing trees and a drawing framework for positioning the nodes such that the result is a planar radial layout. Radial drawings make good use of the screen space. An XML-based file format for the storing of graph data is presented. The design o...

The objective of this study was to compare the blood pressure (BP) measurements during night time sleep of a non-invasive, near-continuous, radial BP instrument to a conventional ambulatory blood pressure monitoring (ABPM) device in a field study setting, in which individuals were not controlled for moving. In order to assess the validity of the radial BP meter in a field setting, we carried ou...

A t-regular graph of radius s is radial Moore if it has diameter at most s + 1 and 1 + t + t(t−1) + . . . + t(t−1)s−1 vertices. We construct radial Moore graphs of radius 3 and degrees t = 3, 5, 7, 9, 10, . . . , 30 with at least t + 1 central vertices and at most t + 2 orbits under the automorphism group.
