Buckling Stability of Cylindrical Shells: Classical Theory, Nonlinear Analysis, and Design Implications
* Today * Wednesday 21 May 2025, 14:00, M2 (M233)
Cylindrical shell structures display complex and sensitive buckling behavior that challenges both theoretical modeling and practical design. This presentation revisits classical asymptotic shell buckling theory and examines its numerical treatment, emphasizing nonlinear structural mechanics and the ability of modern computational tools to capture critical loads and deformation modes. The derivation and interpretation of design-oriented knockdown factors are discussed in relation to numerical results. Particular attention is given to the spatial characteristics of buckling modes and more interaction which are essential to accurately assess structural stability through numerical analysis.

A system-level approach to generalized feedback Nash equilibrium seeking
* Monday 26 May 2025, 15:00, M2 (M233)
In this presentation, we discuss an algorithm for seeking generalised feedback Nash equilibria (GFNE) in noncooperative dynamic games. The focus is on the feedback control of decentralised networked systems with dynamics which are linear, potentially unstable, and partially observed. We employ System Level Synthesis to reformulate the problem as the search for an equilibrium profile of closed-loop responses to random noise. Under this setup, we leverage monotone operator theory to design a GFNE-seeking algorithm capable to enforce closed-loop stability, operational constraints, and communication constraints onto the feedback policies.

Synthetic longitudinal patient data generation: opportunities and limitations
* Tuesday 27 May 2025, 15:15, M2 (M233)
Synthetic longitudinal patient data (LPD) offers a solution to challenges related to data privacy and availability. It involves generating data that mimics real patient information for use in research, development, innovation as well as education. This presentation will explore the concept of synthetic and longitudinal data, review methods for generating and evaluating synthetic longitudinal patient data, and address the limitations and future directions in the field of synthetic LPD generation.
