Such processes are characterized by the operations of batch processes generating periodic strong disturbances to the continuous processes and traditional regulatory controllers are unable to eliminate these periodic disturbances. ILMPC integrates the feature of iterative learning control （ILC） handling repetitive signal and the flexibility of model predictive control （MPC）. By on-line monitoring the operation status of batch processes, an event-driven iterative learning algorithm for batch repetitive disturbances is initiated and the soft constraints are adjusted timely as the feasible region is away from the desired operating zone. The results of an industrial application show that the proposed ILMPC method is effective for a class of continuous/batch processes.展开更多

Can patients/older people be treated, monitored, and managed successfully with mobile and wearable technologies？ The project involved three different groups of patients/participants： Patients with heart failure shock in ＂Home Monitoring Scenario＂; Patients with different pathologies in ＂Virtual Ward Scenario＂; Patients with limited mobility due to Neurological and Orthopaedic disease in ＂Rehabilitation Scenario＂. Due to the complexity of the issue, the methodological approach adopted must be multidimensional and interdisciplinary, addressing the complexity of the chronic patient from all viewpoints, not reducing it, yet analysing, understanding, rearranging, and managing it in an organic manner. The three different scenarios were allowed to identify several impacts on organizational and clinic management of chronic diseases, the tests showed significant improvements in quality of life of patients enrolled in the project. The data deriving from the three scenario demonstrate that wearable divide and ICT, in general, can empower both patients and physician personnel allowing them to be active part in the chronic disease management process. The PRO DOMO SUD experience derived from the Living Lab, this is a new paradigm for industrial research and development activities which allows the final users to actively collaborate with the designers and technicians in the development and test of new products and services aimed to them. The Living Labs stimulate social innovation by transferring research results from the closed industrial laboratory towards real life contexts where citizens and users become co-developers.展开更多

This paper is based on a specific individual study and on empirical evidence collected using various techniques. It demonstrates how the management of the technological learning process and the innovation system boost the growth trajectory in a small company, by the fact that they contribute to the effective development of technological competencies considered fundamental to perfect the level of competitiveness of the company.展开更多
