AE Seminar

he constructive role of temporal disorder (random noise) in facilitating responses of nonlinear systems will be explored in this talk, through a combination of experimental and numerical investigations. In particular, nonlinear oscillators and nonlinear oscillator arrays will be considered. These oscillator systems represent models of micro-scale and macro-scale systems and energy harvester systems. It is […]

Air Marshal TD Joseph examines aerospace power as a critical instrument of statecraft, highlighting its strategic, coercive, and diplomatic roles in modern conflict and international relations. The latest example is India itself choosing aerospace power as the first instrument of choice to punish the enemy as in ‘Op Sindoor’. Drawing on historical and contemporary examples […]

Over the past decade, the fluidic pinball has become a valuable benchmarkfor studying flow control strategies. The configuration consists of three independently rotating cylinders positioned at the vertices of an equilateral triangle, with the flow directed perpendicularly to one of its sides. The cylinder rotation rates serve as the control inputs, while velocity sensors located […]

This talk presents a comprehensive overview of advanced fluidic and thermal management strategies across biomedical and defense applications. We begin with a systematic evaluation of Particle Image Velocimetry (PIV), specifically addressing the challenges of simultaneous velocity and particle size measurement. By analyzing Gaussian intensity variations across the light sheet and the optical system’s depth of […]

A mathematical framework is presented to guide the search for Rayleigh waves in lattice materials based on periodic structure theory and the Bloch theorem. Architected materials with a periodic microstructure are distinguished from crystals in continuum anisotropic elasticity by the presence of at least one length scale and a band structure with partial and complete […]

Fluid flows in nature and engineering exhibit a wide range of spatial and temporal scales. This talk presents two problems across this range: compressible turbulence in channel flows and large-scale vorticity dynamics in the tropical atmosphere. The first part of the talk focuses on compressible turbulence, which plays a key role in many aerospace flows, […]

AI in general and Agentic AI Frameworks in particular have begun to appear in safety critical and mission critical application of autonomous systems. Assurance of their behavior lags behind in terms of principles, tools and engineering practice. In this presentation I will cover some emerging approaches that are both powerful and practical, and easily understood […]

As civil and military aircraft evolve toward increasingly complex designs and intelligent systems, understanding pilot–vehicle interactions and their impact on safety and performance remains essential. Rotorcraft shipboard landing is among the most demanding flight operations, requiring pilots to contend with degraded and rapidly changing visual cues, deck motion, and environmental disturbances, often resulting in elevated […]

Autonomous robots operating in challenging environments must make reliable decisions under geometric, dynamic, and environmental constraints. In such settings, motion planning plays a central role in enabling robots to move safely and efficiently through cluttered, narrow, disconnected or uncertain spaces, while balancing feasibility, robustness, and computational efficiency. This talk will focus on motion planning for […]
