Stanford University released the world’s top 2% scientists in 2021

I have been named in the world’s top 2% scientists, considering all fields and subfields of research. This list has been recently released by the US-based Stanford University.

November 2021: Stanford University has recently released a list that represents the most-cited scientists in various disciplines by analyzing the quality of research cited by other researchers in year 2021 – the World’s Top 2% Scientists. This ranking, considered as the most prestigious worldwide, is based on the bibliometric information contained in the Scopus database, and includes more than 180,000 researchers from the more than 8 million scientists considered to be active worldwide, with 22 scientific fields and 176 subfields taken into account. The Stanford ranking is based on a composite citation index that excludes self-citations and considers the position of researchers in the authorship of papers, with emphasis on single, first and last authorship. The same index including self-citations is provided for comparison.

Advanced FDI for the A350 aircraft

Today, Airbus A350 XWB is undoubtedly the most modern and efficient commercial jetliner in the world. Since January 2015, this aircraft is flying worldwide with a high performance robust model-based monitoring system on-boarded. This exceptional achievement has been resulted from an inspiring collaboration between my research team and Airbus on FDIR issues in aircraft systems, starting with mid-2000s. With current airworthiness certification standards in civil aviation, extremely rigorous specifications must be satisfied, not only in nominal flight regimes, but also in extreme, unusual, non-standard/off-nominal and unexpected flight conditions. The certification testifies that new systems meet all requirements set by the aviation regulatory authorities — FDA (USA) and EASA (Europe) — and that they themselves do not introduce new risks. Achieving flight-proven and certified model-based monitoring systems has been a tall order and required several years of research and innovation, ground V&V activities and in-flight tests and maturation.

Five years after the first A350 commercial flight, this note posted on the IFAC Blog and IFAC social media looks back at some lessons learnt from this amazing success story. The note has been prepared by Dr. Philippe Goupil (eXpert FDIR – A/C Control Architecture & Functions, Airbus, Toulouse – France) and myself. See also IFAC Newsletter, December 2020.

What about the aircraft of the 2030s and beyond? In civil aviation operations, the vector is pointed toward more autonomy and intelligence in the cockpit. Future avionics will have to ensure more autonomy and must provide safety functionalities at least equivalent to those of today blended-crew task environments, while coupled to a new cockpit concept. The next leap forward will be to take one pilot out of the cockpit (Single Pilot Operations, SPO). Improved flight management in SPO requires cross-domain methods for trustworthy, robust and scalable detection and mitigation of anomalous events.

Covid travel restrictions: stay of Prof. Lee in Bordeaux has been cancelled

Due to covid-19 travel restrictions, the stay of Prof. Edward Lee in April has been canceled – and will hopefully be postponed.

Stay of Prof. Edward Lee – UC Berkeley, USA – at the IMS lab (April 2020)

I  have the pleasure to welcome Prof. Edward A. Lee (Robert S. Pepper Distinguished Professor, University of California — Berkeley, USA) in April 2020 in Bordeaux. Prof. Lee is an internationally recognized pioneer in research in Cyber-Physical Systems (CPS). He has delivered more than 180 keynote talks and other invited talks at venues worldwide (h-index=84 with more than 48000 citations). He has pointed out the failure of standard abstraction layers, the need of reliable timing behavior, and lack of temporal semantics of existing programming language models for CPS design. Prof. Lee has led the development of several influential open-source software packages, notably Ptolemy and its various spinoffs. See his resume here.

During his stay, he will share his experience on open issues in CPS modeling, control and safety management, and emerging Artificial Intelligence (AI) issues. His coming to the University of Bordeaux is supported by the cluster SysNum. He will give a conference on “interaction, observation (and Determinism and Free Will)” on April 14, 2020, at 10:00, at the IMS lab:

 

Abstract:
Interaction is more powerful than observation. This may help to explain the recent revolution in machine learning, the power of feedback systems, the limitations of the Turing-Church model of computation, the differences between cyber-physical systems and computing systems, and the limits of objectivity. But what is interaction? It requires first-person involvement, a self, but the concept of "a self" is treacherous. In this talk, I examine the differences between interaction and observation from a technical point of view. I leverage the results of four Turing Award winners, starting with the concept of a zero-knowledge proof (introduced by Shafi Goldwasser and Silvio Micali), which requires first-person interaction. I continue with Judea Perle's demonstration that observation of data alone, without any interaction with the mechanisms that produce the data, cannot be used, by itself, to infer causality. It reveals only correlation. I then show that this observation has a strong connection to a classic result by Robin Milner, who shows that two automata that cannot be distinguished by observation alone may be able to be distinguished through interaction. These technical interpretations of interactions lead inevitably to treacherous ground, connecting with deep philosophical questions about determinism and free will.

 

More details will be available soon.
