Abstract: An integrated speed prediction framework based on historical traffic data mining and real-time V2I communications for CAVs. The present framework provides multi-horizon speed predictions with different fidelity over short and long horizons. The present multi-horizon speed prediction is integrated with an economic model predictive control (MPC) strategy for the battery thermal management (BTM) of connected and automated electric vehicles (EVs) as a case study. The simulation results over real-world urban driving cycles confirm the enhanced prediction performance of the present data mining strategy over long prediction horizons. Despite the uncertainty in long-range CAV speed predictions, the vehicle level simulation results show that 14% and 19% energy savings can be accumulated sequentially through eco-driving and BTM optimization (eco-cooling), respectively, when compared with normal-driving and conventional BTM strategy.

Abstract: Due to geometric discontinuities introduced by welding and joining processes, stresses or strain cannot be calculated reliably calculated using modern analytical and computer methods as result of stress or strain singularity at joint locations, which leads to severe mesh sensitivity. Design and fatigue evaluation of these structures remain empirical.

Abstract: Cameras provide an easy-to-deploy and information-rich datastream for a wide range of ubiquitous sensing and health monitoring applications. However, their unrestricted operation often captures personally identifiable information (PII), preventing their use in privacy-sensitive settings, such as the home, workplace, and hospitals. This disclosure proposes pairing RGB and thermal imaging to robustly detect and remove PII (e.g., an individual's face, skin color, gender, body shape, etc.,) from images before they are stored or sent off the device. A dual camera prototype includes an onboard embedded GPU capable of performing real-time privacy sanitization tasks at 8FPS at under 5 W power consumption. Results show that in the most fail safe settings the system completely removes all PII.

Abstract: Plasmonic nanostructures function as an antenna-reactor nanostructure to focus and convert light into thermal/chemical energy, and thus have significant potential for sustainable solar water disinfection. However, the insufficient energy harvesting efficiency resulting from inconsistent nano-features linked with arrangement and scaling is a persistent challenge. An integrated optofluidic fabrication method is presented to produce a high density integrative plasmonic dimer array to enhance solar water disinfection. The plasmonic dimer array is constructed by a combined fabrication of self-assembly monolayer method and block-co-polymer lithography approaches. This combination leads to a two-dimensional hexagonal array of dimer structures consisting of 1.3 nm nanogap. The uniformity and high density of the nanogaps in the plasmonic dimer array allows strong light focusing and a rapid and highly efficient harvesting of photothermal energy at visible and near-infrared region.
