Modern myoelectric hand prostheses continue to increase in functionality, while their control is constrained by the limits of myoelectric input. This paper covers the development and testing of grasp controlsystems for multifunctional myoelectric prosthetic hands. The functionality of modern hand prostheses is often focused on the task of grasping, which can be divided into high-level grasp planning and low-level finger control. Initially, models can used to test these controlsystems, but for proper evaluation actual implementation on a physical system is required. The University of Bologna (UB) Hand IV prototype is an anthropomorphic, tendon-driven robotic hand, which makes it well-suited to represent the structure of modern prostheses. One of the main controlsystems tested in this paper is based on the intrinsically passive controller (IPC), the structure of which offers guaranteed passivity and stability. After several grasping tests, the systems are evaluated on compliant behavior, grasping ability, and dynamic appearance. IPC proves to be a powerful approach to interaction control, without the associated sensor requirements which could be difficult to meet in modern hand prostheses.

The problem of the distributed identification of a macroscopic first-order traffic model, viz. the Cell Transmission Model (CTM), is considered in the paper. The parameters to be identified characterize the dynamics of the density in different sections of the freeway (cells). We explore different distributed identification schemes. The purposes of the approach are mainly to obtain good prediction models through the minimization of the one-step ahead prediction error of the densities of the cells, and to reduce the computational time and the effort required to perform the identification. The methodology is validated relying on real-life data measured on a portion of the A12 freeway in The Netherlands. An evaluation of the performance of the identified model used as a set of virtual sensors in different scenarios is presented.

Therapeutic decision support can be used to promptly assist clinical decision making process. This paper presents a new approach to interpreting multiple data streams in intensive care environments, the resulting model can be used to correct and maintain patients’ health whilst treating underlying illnesses. Rather than simply directing which treatments to be applied, multiple suggestive treatment pathways can be provided allowing several “what-if” scenarios to choose from. Hyper-heuristics are used to guide the treatments and therapeutic pathways selection. Algorithmic validation is made using a human cardiovascular system model parameterised with various post surgery conditions.

The IEEE RAS Ontologies for Robotics and Automation Working Group is dedicated to developing a methodology for knowledge representation and reasoning in robotics and automation. As part of this working group, the Autonomous Robots sub-group is tasked with developing ontology modules for autonomous robots. This paper describes the work in progress on the development of ontologies for autonomous systems. For autonomous systems, the focus is on the cooperation, coordination, and communication of multiple unmanned aerial vehicles (UAVs), unmanned ground vehicles (UGVs), and autonomous underwater vehicles (AUVs). The ontologies serve as a framework for working out concepts of employment with multiple vehicles for a variety of operational scenarios with emphasis on collaborative and cooperative missions.

This paper deals with the introduction and exploitation of space technologies based on the ERTMS (European Railways Train Management System) architecture bundling the EGNOS-Galileo infrastructures in the train control system, in order to improve performance and enhancing safety, reducing the investments on the railways circuitry and its maintenance. These solutions can be successfully applied for local and regional lines and low traffic lines, where the issue for a railroad enhanced service, requires increasingly financing to maintain and improve infrastructure. In order to assess the performance and validate the space technologies in a real railways environment, a special focus will be dedicated to the case of the regional lines in Sardinia where is a plan to deploy a Test Site.
In this paper, we describe a system that can carry out visual simultaneous localization and mapping (VSLAM) in structured indoor environments;this system uses a small-sized low-cost commercial humanoid robot which use...

A problem of optimised robust placement of the hard quality sensors in Drinking Water Distribution systems under several water demand scenarios for robust quality monitoring is formulated. Numerical algorithms to solve the problem are derived. The optimality is meant as achieving at the same time a desired trade off between the sensor capital and maintenance costs and resulting robust estimation accuracy of the monitoring algorithm for several water demand scenarios insuring robustness with respect to the demand uncertainty. The robust estimation algorithm recently developed by the authors is applied as a soft quality in design of the sensor placement algorithms. The method and algorithm are validated by application to Chojnice DWDS case study.

This paper explores the computational efficiency of the recently developed Laguerre optimal MPC. Laguerre OMPC facilitates substantial improvements in feasibility with lit- tle or no detriment to performance while not increasing the number of optimisation variables. However, it is shown that some of the structure of the optimisation problem is lost when using a Laguerre parameterisation. In contrast, Optimal MPC can has a strong structure which can be exploited in the active set method thus allowing relatively in- expensive optimisation with large numbers of degrees of freedom. This paper contrasts the two approaches to predictive control and in particular the computational load us- ing both a generic optimiser and active set methods.
control of a spatiotemporal field with mobile agents has received considerable recent interest. A key problem in this area is the tendency of agents to become static once a local control objective is met. To overcome ...
