Cardiac tamponade from a giant thymoma: case report

Thymoma, the most common neoplasm of the anterior mediastinum especially in adults, accounts for 20-25% of all mediastinal tumors and 50% of anterior mediastinal masses. These tumors are routinely asymptomatic for prolonged periods of time. Pericardial tamponade is a very rare initial manifestation of a thymoma. This report presents a patient who had hemorrhagic pericardial tamponade that likely resulted from the largest symptomatic mixed type (type AB) thymoma described in the literature

La conservazione preventiva del patrimonio librario come possibile alternativa al restauro tradizionale

The present paper focuses on the close relation between library collections and their preservation environment, aiming, in particular, at highlighting the importance of promoting and sustaining the monitoring. The paper proposes some simple and ready-to-use technologies – smart monitoring – to prevent future damages

Open-loop intermittent feedback control: Practical continuous-time GPC

A conceptual, and practical difficulty with the continuous-time generalised predictive controller is solved by replacing the continuously moving horizon by an intermittently moving horizon. This allows slow optimisation to occur concurrently with a fast control action. Some nonlinear simulations illustrate the potential of this approach

Nonlinear Continuous-Time Generalised Predictive Control Through Successive System Linearisations

Non linear predictive control may require significant off-line and online computations. This paper gives a nonlinear predictive control algorithm based on successive off-equilibrium linearisation which requires less computation whilst accounting for nonlinear system behaviour. A nonlinear example (the pendulum and cart system) is used to show that the method provides a practical tradeoff between computational requirements and performance. 1 Introduction Predictive control based on non-linear models often requires significant computations, both off-line and on-line. This can preclude practical implementation when processor power is limited and yet high bandwidth control is required. This is particularly true in the context of mechanical systems which typically have much higher closed loop bandwidth that process engineering systems. Different algorithms have been proposed to enable a faster optimisation (see for instance [19, 21, 20]). Alternatively, an intermittent receding horizon a..
