Abstract: The presentation opens with a comparison of high-temperature materials with everyday metals. This will be followed by a discussion of challenges and an understanding of the machinability of high-temperature materials. Next, various strategies for machining high-temperature materials, along with practical real-life case studies, will be presented. We will be introducing the concept of Feed […]

Laser beam is highly affected by prevailing atmospheric conditions and limit the system performance for various applications. The talk mainly covers the cause of optical turbulence, its effects on laser beam and further discuss the technologies for controlling the beam for enhancing the effectiveness. Two main techniques namely the Tip-tilt correction for maintaining the beam […]

Miniaturised technologies, due to their portability, rapid responses, low powers and ability of multi-component integration, have received an ever-growing interest in areas like healthcare, air quality, and space research. This talk will provide an overview of my research in 3 domains of miniaturised technologies: a) microfluidics, b) MEMS sensors and c) nanoaerosol instruments. I will […]

Some decades ago J. T. Stuart formulated a theory for nonlinear saturation of hydrodynamically unstable modes. He proposed that an unstable mode, upon gaining sufficient energy, distorts the mean flow. This mean flow distortion reduces the shear, thus reducing the inviscid energy production mechanism which eventually results in a saturation of instability. In a hypersonic […]

Since the Apollo era, space has become an increasingly valuable domain for national security due to diplomatic, informational, and economic reasons. The last few years have seen exponential growth in the launch of space objects and there is an increased interest in having a permanent cislunar presence through the Artemis program. The understanding of motion […]
