Advanced Methods for Generating and Processing Simulated Radar Sounder Data for Planetary Missions
Radar sounders (RS) are active instruments that have proved to be able to profile the subsurface of planetary bodies. The design of RS instruments, as well as the interpretation of the acquired data, is a non-trivial task due to the complexity of the scenario of acquisition and the limited amount …

Smart Surgical Needle Actuated by Shape Memory Alloys for Percutaneous Procedures
… errors of surgeons/physicians. Therefore, active needles were proposed recently where actuation forces provided by shape memory alloys (SMAs) are utilized to assist the maneuverability and accuracy of surgical needles. This work also aims to introduce a novel needle insertion simulation to …
