ABSTRACT – This tutorial will provide key insights into superconducting technology (bulks and tapes) for electric power systems and methodological approaches to estimate their design and performance. First, technical challenges are presented and discussed, along with current developments on how to overcome them. Then, their physical phenomena are explained, from a macroscopic point of view, for DC and AC magnetic fields and currents. A methodology is provided to analyze their performance in simple and complex systems using Finite Element and analytical modelling. Finally, a case study is presented comparing a conventional synchronous machine to a superconducting one. Upon completion, the attendees will obtain an important overview of the potential and challenges of superconducting technology and tools to evaluate superconducting systems.

ABSTRACT – The demand for more immersive and interactive experiences has driven the use of new 3D multimedia formats, more fitted to virtual and augmented reality applications. Among these formats, point clouds (PCs) have gained relevance, due to their ability to represent the scenes’ 3D visual information, using a set of points and associated attributes, notably color. To offer realistic and immersive experiences, PCs need millions, or even billions, of points, thus asking for efficient representation and coding solutions, which are critical for the practical deployment of emerging applications and services.

This tutorial will focus on the DL-based point cloud representation state-of-the-art and emerging trends. The potential of the DL-based coding has been recognized by JPEG and MPEG which have started projects towards standardizing DL-based PC coding solutions. Among these, the JPEG Pleno project is leading the efforts for the development of a new PC coding standard. These initiatives clearly demonstrate that the multimedia coding landscape is facing a revolution with the emergence of DL-based technology, not only supported by gains in compression efficiency when compared with previous hand-crafted coding solutions, but also on its potential to offer an effective, common, unique representation for both human visualization and machine consumption. In this context, computer vision tasks will be performed in the latent/compressed domain with high accuracy and not after decoding, thus suffering from compression artifacts, as it happens nowadays. The compressed domain processing will not only allow to use features directly extracted from the PC originals but will also allow to save the complexity associated with the decoding process.

Considering the fast changing pace of the disruptive new approaches in the multimedia coding arena brought by the DL-based algorithms, this tutorial targets members of the multimedia signal processing community, providing a first person testimony of some of the most recent developments in DL-based PC representation and compressed domain processing techniques.

ABSTRACT – In the last decades, the occurrence of extreme weather events (EWEs) increased and endangered both human lives and infrastructures. EWEs are usually classified as High-Impact/Low-Probability (HILP) events because they strongly affect the proper operation of the infrastructures, but their occurrence rate is not so high (yet). The electrical grid (and the distribution system in particular) is one of the infrastructures more under pressure, because i) it is extended and widespread in the territory, ii) most of its components are aged, and iii) its design was not based on events of such magnitude, because of their (past) low occurrence frequency. The impact of HILP phenomena on the electrical grid varies according to its resilience, i.e., its attitude to withstand extreme events and to absorb the stress due the hazard occurrence. But: how can be defined the resilience for the electrical system? How can we treat it? Which is the state-of-the-art about this topic? What about future trends? This tutorial aims to introduce the audience to the resilience topic, by focusing on real-world case studies involving the distribution system.
