IEEE JETCAS Special Issue on Unconventional Computing Techniques for Emerging Technology Applications - Guest Edited by Professor Pavlos P. Sotiriadis

Congratulations to Professor Pavlos P. Sotiriadis, of the School of Electrical and Computer Engineering of the NTUA, for leading the Guest Editorial team of the recent IEEE Journal on Emerging and Selected Topics in Circuits and Systems (JETCAS) Special Issue on Unconventional Computing Techniques for Emerging Technology Applications, and to ECE-NTUA recent Ph.D. graduate, Dr. Nikos Temenos for coordinating the effort.

The Special Issue was dedicated to the latest developments in the interdisciplinary field of unconventional computing, focused on three main directions: 1) Novel Techniques and Approaches in Unconventional Computing, 2) Circuits, Systems, and Architectures for Approximate and Stochastic Computing, and, 3) In- and Near-Memory Processing with an emphasis on Memristive Devices Utilization.

The announcement of the Special Issue created excitement in the international research community, attracting more than 70 high quality contributions. Of these, 36 were rigorously selected for the Special Issue. Research groups from major universities, research companies, and national research labs around the world contributed their latest research results. The following is a partial list of affiliations of the contributors:

Universities: Arizona State University, Bar-Ilan University, Concordia University, Georgia Institute of Technology, Indian Institute of Technology, Karlsruhe Institute of Technology, Khalifa University of Science and Technology, McGill University, National Chung Hsing University, National Taiwan University, National Technical University of Athens, Northeastern University, Technion - Israel Institute of Technology, Texas A&M University, Politecnico di Torino, The George Washington University, Tohoku University, Tsinghua University, TU Wien, Universidade de Lisboa Instituto Superior, University of California San Diego, University of Edinburgh, University of Stuttgart, TU Dortmund, Washington University.

Major research companies: IBM Zurich Research Laboratory, Intel Corporation.

National research labs: National Institute of Standards and Technology USA, NCSR Demokritos Greece

The IEEE Journal on Emerging and Selected Topics in Circuits and Systems (JETCAS) is a premier journal of the IEEE Circuits and Systems Society. With a high Impact Factor (~5.9), JETCAS covers the entire field of interest of the theory, analysis, design, tools, and implementation of circuits and systems. This includes theoretical foundations, applications, and architectures, as well as the circuits and systems implementation of algorithms for signal and information processing. JETCAS has a particular focus on emerging areas in the field.

Professor Paul Sotiriadis was named IEEE Fellow!

We are thrilled to announce that Prof. Paul Sotiriadis of the School of Electrical and Computer Engineering - NTUA (National Technical University of Athens) has been named a 2023 IEEE Fellow for his contributions to Advanced Frequency Synthesis and High-Speed Data Buses. This is a great recognition of his contributions to two important technical areas: Frequency Synthesis, which is of fundamental importance to Radar, Telecommunications, Navigation, Timing, Instrumentation and other systems, and, (on-chip) High-Speed Data Buses (optimization) for increasing on-chip data transmission speed and power efficiency. His work has been adopted by the industry and has been included in technical books, which is an important criterion for elevation to the Fellow level. IEEE Fellow is one of IEEE's most prestigious Honors and the highest grade of IEEE membership, awarded to a very limited number of Senior Members who have made significant contributions to the advancement or application of Engineering, Science and Technology. According to the IEEE Fellows Directory, Prof. Sotiriadis is the only IEEE Fellow in the technical area of Integrated Circuits in Greece, one of the 8 IEEE Fellows who are members of our School, and, one of the 26 IEEE Fellows in Greece.


ECE-NTUA Undergraduate and Graduate students attended and volunteered for the international MIT Global Startup Workshop 2023

ECE-NTUA undergraduate and graduate students played a key role in the successful organization of the prestigious MIT Global Startup Workshop 2023, which was held in Athens last week. According to Bill Aulet, a renowned entrepreneurship educator from MIT, this was the most successful GSW in the series since its launch in 1998. The workshop brought together entrepreneurs, students, investors, and other stakeholders from various fields to foster the entrepreneurial ecosystem of the host region. With over 1,300 attendees, almost 400 of whom were students, the event featured tailored workshops, keynote speakers, and panel discussions with distinguished technology entrepreneurs and investors in fields ranging from artificial intelligence to fusion reactors. The atmosphere was exhilarating, and the students had the opportunity to network and engage with these experts, gaining invaluable insights into the world of startups. Overall, the workshop provided a unique opportunity for the students to learn from the best and take a step closer to their shared dream of becoming successful entrepreneurs.

The MIT Global Startup Workshop (MIT GSW) is an international annual conference that brings together entrepreneurs, students, investors, and stakeholders from around the world to accelerate the entrepreneurial ecosystem of the host region. It shares the entrepreneurial practices that empowered over 30,000 companies to launch from MIT affiliates, with a cumulative annual revenue of nearly $2 trillion. Organized by a diverse group of graduate students at MIT, the conference receives robust support from the MIT entrepreneurial ecosystem and has attracted participants from over 70 countries.
