Design and control of an active ankle-foot orthosis
(2022-04-01)
Active ankle-foot orthoses (AAFOs) assist a user unable to dorsiflex the ankle joint. The optimal AAFO is lightweight and aids the user in achieving a nominal gait.
This thesis presents the design and control of a novel ...
Efficient design of reconfigurable intelligent surface assisted multi-group multicast beamforming
(2023-09-01)
This thesis considers a multi-group multicasting scenario facilitated by a reconfigurable intelligent surface (RIS). We propose low-complexity scalable algorithms for the joint design of the base station (BS) multicast ...
