In order to guide the design of a new multi-robot system, we seek to evaluate two different designs of audio direction sensor. We have implemented a simple but useful audio propagation simulator as an extension to the stage multi-robot simulator. We use the simulator to evaluate the use of audio signals to improve the performance of a team of robots at a prototypical search task. The results indicate that, for this task, (i) audio can significantly improve team performance, and (ii) binary discrimination of the direction of a sound source (left/right) performs no worse than high-resolution direction information. This result suggests that a simple two-microphone audio system would be useful for our real robots, without advanced signal processing to find sound direction

Accepting recent proposals to supporting dependable e-health enterprise systems via the adoption of emerging autonomic grid computing and services-oriented architecture (SOA); this paper presents the motivations for a novel semantics/knowledge plane for a service-oriented e-health middleware and applications. The paper starts by a detailed description of a developed sensor and actuator framework and overlay. This is followed by, and illustrated using a remote healthcare monitoring scenario. A case-study of pregnancy monitoring is used to illustrate the design and usability of such a grid overlay. Finally, the paper concludes with general remarks and a statement of further work

This paper presents an intelligent online monitoring system for business enterprise applications based on grid computing overlay to improve QoS, performance, fidelity, and reliability of the system. This paper starts by describing a grid-based architectural model for financial application services, which is underpinned by a proposed sensor and actuator framework to provide context, governance and self awareness capabilities to ensure self management behaviour of the system. In particular, load monitoring of users account services is used in this paper illustrating and detailing the proposed architecture. The paper concludes with an evaluation and general concluding remarks

This paper presents the motivations behind the development of a novel knowledge plane to extend e-health service-oriented application services. The paper starts by a brief description of service-oriented architecture applied to remote health monitoring and execution system, which is implemented as a massively-distributed sensor and actuator grid overlay. This will be followed by an illustrative example of pregnancy monitoring is used to detail the proposed architecture and operation. Finally, the paper concludes with general remarks and a statement of further work

In this article a new approach to planning of a nonholonomic motion is presented. A flexible, intelligent planner based on a static map and the topology of the robot's environment has been developed. The approach uses 'particles' to construct automatically a path between two given locations. The generated path is a smooth trajectory, where the length of the path is kept at a minimum and obstacles are avoided. This concept applies to robots meeting the restrictions of a Dubin's car (nonholonomic robot that can only move forward). After the basic concepts of the approach has been described, simulations will be presented

The algebraic structure and Poisson＇s integral theory of mechanico-electrical systems are studied. The Hamilton canonical equations and generalized Hamilton canonical equations and their the contravariant algebraic forms for mechanico-electrical systems are obtained. The Lie algebraic structure and the Poisson＇s integral theory of Lagrange mechanico-electrical systems are derived. The Lie algebraic structure admitted and Poisson＇s integral theory of the Lagrange-Maxwell mechanico-electrical systems are presented. Two examples are presented to illustrate these results.

详细信息
Non-Noether symmetries and conservative quantities of nonholonomic nonconservative dynamical systems are investigated in this paper. Based on the relationships among motion, nonconservative forces, nonholonomic constrained forces and Lagrangian, non-Noether symmetries and Lutzky conservative quantities are presented for nonholonomic nonconservative dynamical systems. The relation between non-Noether symmetry and Noether symmetry is discussed and it is further shown that non-Noether conservative quantities can be obtained by a complete set of Noether invariants. Finally, an example is given to illustrate these results.

This work describes and compares two different methods for identifying growth patterns in preterm infants during the second year of development. One method is based on creating anatomical atlases from the population of subjects within each timepoint and using the transformation between atlases at different timepoints to create average volume change maps. The second method uses multiple longitudinal intra-subject registrations to produce individual volume change maps. These maps are then transformed into a common coordinate system and averaged with the method used for atlas creation. We show that there is a reasonable level of agreement between the two methods and both generate plausible growth patterns implying that either could be used to track development during this period of growth
