Unlocking the hidden capacity of the electrical grid through power electronics


Marco Liserre
University of Kiel, Germany




Abstract : Studies have revealed that the actual electrical grid is less utilized than 25 years ago: there is a higher utilization for a shorter time. This “greater demand variability” has been mostly caused by new loads, like air conditioning, but also by changes in the industrialization landscape. The wider integration of renewable energies and new loads(like heat pumps and electric vehicle charging stations) is expected to worsen the situation resulting in further congestion or underutilization of the electrical network, while their control(e. g. Load Demand Response) could relive the problem. The use of direct current(Hybrid grid) and the coordination among more energy carriers(Multimodal grids) together with Smart Grid technologies, is attempting to give to the electrical grid more flexibility in controlling the power flow by exchanging it with the dc-infrastructure or with other energy layers. Power Electronics is a key technology in all these solutions and offer the possibility to unlock the hidden potential of the grid without the need of a massive reinforcement of the electrical infrastructure.

Using Everyday Routines for Understanding Health Behaviors


Anind K. Dey
University of Washington, USA




Abstract: We live in a world where the promise of ubiquitous computing and the Internet of Things is coming true. We have smart devices that pervade our lives, and that are constantly collecting data about us and mostly discarded as irrelevant. I will demonstrate how researchers can extract relevance from this passively collected data and use it to "image" people's behaviors. I will describe approaches for extracting behavioral routines from smart devices, and then how these routines can help us better understand individual and group human behaviors, as well as anomalies. Using examples from healthcare, I will describe how we can leverage both the routines and anomalies to improve our understanding of health-related behaviors and support behavior change.

Anind K. Dey is a Professor and Dean of the Information School and Adjunct Professor in the Department of Human-Centered Design and Engineering. Anind is renowned for his early work in context-aware computing, an important theme in modern computing, where computational processes are aware of the context in which they operate and can adapt appropriately to that context. His research is at the intersection of human-computer interaction, machine learning, and ubiquitous computing. For the past few years, Anind has focused on passively collecting large amounts of data about how people interact with their phones and the objects around them, to use for producing detection and classification models for human behaviors of interest. He applies a human-centered and problem-based approach through a collaboration with an amazing collection of domain experts in areas of substance abuse (alcohol, marijuana, opioids), mental health, driving and transportation needs, smart spaces, sustainability, and education. Anind was inducted into the ACM SIGCHI Academy for his significant contributions to the field of human-computer interaction in 2015.




Energy Technologies for Future Grids


Kashem M. Muttaqi
University of Wollongong, Australia




Abstract: New and modern energy technologies will make a significant change in the operation of electricity systems in future power grids. The current power grids are undergoing an unprecedented transformation, changing the way we have been producing, delivering, and consuming energy over the past century. This new energy era includes renewable sources and energy storage, integrated to power grids through power converters and transformers. In the future, these resources will be interfaced through high frequency magnetic links and solid state transformers. Electric vehicles and energy efficient technologies are also rapidly emerging and interacting with the grids. As these connections are being evolved, it is causing the engineers to rethink the current paradigms of system analysis and planning with a focus on how they can achieve the most flexible, efficient, and reliable power grid for the future.

Recent Advances in Learned Image and Video Compression


Ahmet Murat Tekalp
Koç University, Turkey




Abstract: Conventional video compression methods employ a linear transform and block motion model, and the steps of motion estimation, mode and quantization parameter selection, and entropy coding are optimized individually due to the combinatorial nature of the end-to-end optimization problem. Learned video compression allows end-to-end rate-distortion (R-D) optimized training of nonlinear transform, motion compensation and entropy model simultaneously. I will first review recent advances in learned image compression. Then, I will discuss the state-of-the-art in learned video compression and present recent results on learned hierarchical bi-directional video compression that combines the benefits of hierarchical bi-directional motion compensation and~end-to-end rate-distortion optimization.

Medical image analysis with artificial intelligence


Syoji Kobashi
University of Hyogo, Japan




Abstract: Computer-aided diagnosis (CAD) in medical image analysis (MIA) is one of the expected fields that artificial intelligence (AI), especially deep learning (DL), improves the performance. However, DL alone is not enough to analyze medical images. DL process is just one processing step in the overall CAD system. Rather, the main role of researcher is to develop methods to synthesize data that are processed by the DL models, and methods that derive satisfactory results from the inferred results of the DL model. In order to discuss how to develop AI-based-CAD systems, I will introduce some CAD applications using DL models. It will include fatigue fracture detection in 3-D computer tomography (CT) images, tooth recognition in dental panorama radiograph, finger joint detection in hand radiograph. Through the applications, I am going to summarize the strategy to develop AI-based-CAD systems.
