Multi-UAV cooperative path planning can improve the efficiency of task completion. To deal with space and time conflicts multi-UAVs in complex environments, a multi-collision-based multi-UAV algorithm, multi-conflict-based search (MCBS), is proposed. First, flight constraints UAV are analyzed, three-dimensional environment model established that incorporates geographical information. Then, hier...

In this paper, we construct context-independent single-path and multi-path syllable models aimed at improved pronunciation variation modelling. We use phonetic transcriptions to define the topologies of the syllable models and to initialise the model parameters, and the Baum-Welch algorithm for the re-estimation of the model parameters. We hypothesise that the richer topology of multi-path syll...

—The goal of traffic management is efficiently utilizing network resources via adapting of source sending rates and routes selection. Traditionally, this problem is formulated into a utilization maximization problem. The single-path routing scheme fails to react to instantaneous network congestion. Multi-path routing schemes thus have been proposed aiming at improving network efficiency. Unfort...

Providing quality-of-service (QoS) guarantees in packet networks gives rise to several challenging issues. One of them is how to determine a feasible path that satisfies a set of constraints while maintaining high utilization of network resources. The latter objective implies the need to impose an additional optimality requirement on the feasibility problem. This can be done through a primary c...

Animating goal-driven agents in an environment with obstacles is a time consuming process, particularly when the number of agents is large. In this paper, we introduce an efficient algorithm that creates path plans for objects that move between user defined goal points and avoids collisions. In addition, the system allows “culling” of some of the computation for invisible agents: agents are acc...

In risky applications it is advantageous to use multiple robots in order to improve performances. In a research or patrol scenario robots have to move cooperatively in order to avoid collisions and to improve performance. In this paper we describe the implementation of two variations of a cooperative planning algorithm: Cooperative A* and Cooperative Voronoi A*. The task is decoupled into a ser...

Quality of Service issues of IP networks are mostly related to guaranteeing bandwidth for flows. However, many interactive real-time applications also require this bandwidth in an uninterrupted fashion. This paper describes how multi-path routing and local failure reaction can be employed to provide uninterrupted QoS to applications. We show how multi-path route sets can be found in reasonably ...
