— In this paper, the multi-agent containment problem is investigated. In particular, we focus our efforts on a continuation of our previous work on leader-follower networks , by imposing a hierarchical structure on the network topology. The main idea is to organize the team of autonomous , mobile agents in a multi-layered structure, which enables us to(More)
RFX has been recently modified to improve its capability of controlling different MHD phenomena by means of fast, feedback controlled amplifiers and distributed radial field inductors. The paper, after summarizing the principal results obtained in the past by means of active control of magnetic fields in RFX, describes the recent modifications to the(More)
PURPOSE Super-resolution (SR) image processing produces a high-resolution image from a series of low-resolution images. The aim of this study was to evaluate SR-images based on fluoroscopic flat-detector (FD) acquisition at different frame rates. METHODS Fluoroscopic FD-sequences with 20 frames were obtained with varying pulse frequencies of (1) a line(More)
Isogeometric Analysis (IGA) is a novel discretization technique, introduced in [1], which is based on non-uniform rational B-splines (NURBS). Its main features are that it uses exactly the geometry description given by computer aided design (CAD) software, and that the analysis is performed with shape functions of different (possibly high) regularity. In(More)
