Design, Fabrication and Characterization of the Thermal Filter Assembly on the Solar Ultraviolet Imaging Telescope (SUIT) on-board Aditya- L1
The Solar Ultraviolet Imaging Telescope (SUIT) observes the Sun in the near-ultraviolet regime on board the Aditya-L1 satellite, India's dedicated mission to study the Sun. SUIT will image the Sun in the wavelength range of 200-400 nm using 11 science bandpasses with varying spectral bandwidths between 0.1-58 nm. Within this range, the Sun provides huge incoming solar flux to the telescope that also varies by a factor of ~ 20 from the lower end to the upper end of the wavelength band of interes…

Optimal Navigation in Microfluidics via the Optimization of a Discrete Loss
Optimal path planning and control of microscopic devices navigating in fluid environments is essential for applications ranging from targeted drug delivery to environmental monitoring. These tasks are challenging due to the complexity of microdevice-flow interactions. We introduce a closed-loop control method that optimizes a discrete loss (ODIL) in terms of dynamics and path objectives. In comparison with reinforcement learning, ODIL is more robust, up to three orders faster, and excels in hig…
