Thermal Aware Design Automation Of The Electronic Control System For Autonomous Vehicles, Ajinkya Bankar

FIU Electronic Theses and Dissertations

The autonomous vehicle (AV) technology, due to its tremendous social and economical benefits, is transforming the entire world in the coming decades. However, significant technical challenges still need to be overcome until AVs can be safely, reliably, and massively deployed. Temperature plays a key role in the safety and reliability of an AV, not only because a vehicle is subjected to extreme operating temperatures but also because the increasing computations demand more powerful IC chips, which can lead to higher operating temperature and large thermal gradient. In particular, as the underpinning technology for AV, artificial intelligence (AI) requires substantially increased …

Volitional Control Of Lower-Limb Prosthesis With Vision-Assisted Environmental Awareness, S M Shafiul Hasan

FIU Electronic Theses and Dissertations

Early and reliable prediction of user’s intention to change locomotion mode or speed is critical for a smooth and natural lower limb prosthesis. Meanwhile, incorporation of explicit environmental feedback can facilitate context aware intelligent prosthesis which allows seamless operation in a variety of gait demands. This dissertation introduces environmental awareness through computer vision and enables early and accurate prediction of intention to start, stop or change speeds while walking. Electromyography (EMG), Electroencephalography (EEG), Inertial Measurement Unit (IMU), and Ground Reaction Force (GRF) sensors were used to predict intention to start, stop or increase walking speed. Furthermore, it was investigated whether …

Parameter Estimation And Charge Control In Standalone And Grid-Tied Batteries, Asadullah Khalid

FIU Electronic Theses and Dissertations

Energy storage systems are the critical components enabling an electrified future ranging from electric vehicles (EVs) to microgrid (MG) applications. With the advancements in these applications, the operational dynamics of electrochemical energy storage such as Lithium-ion batteries need to be analyzed from the lifecycle impact, cybersecurity, balancing requirements, and prognostics perspectives. These operations enable the interconnected systems to be secure, efficient, and self-adaptive while reducing greenhouse emissions.

This research aims to develop threefold solutions. The first objective of this dissertation is to analyze lifecycle impact, quantify the interconnection requirements of battery energy storage systems, and evaluate cybersecurity frameworks for battery …
