Abstract GaN high-electron-mobility transistors (HEMTs) have been extensively studied and commercialized due to their superior material properties for high-frequency and high-power applications. To fully harness their potential, GaN-based power ICs have been proposed to develop energy-efficient, high-density integrated circuits and systems. To ensure fail-safe operation, minimize standby power consumption, and facilitate circuit simplicity, enhancement-mode (E-mode) […]

Abstract Reconfigurable surface acoustic wave (SAW) phase shifters are emerging as important components for advancing secure wireless communication, adaptable signal processing, and intelligent sensing technologies.   A promising approach to SAW modulation involves gate voltage-controlled tuning through acoustoelectric interactions, which offers efficient modulation at low bias voltages.   However, current acoustoelectric devices face limitations, such as restricted […]

Abstract Microwave active circuits, such as low-noise amplifiers, power amplifiers, and oscillators, are essential components of the transceivers in the front-end of RF communication systems. As modern communication systems evolve, the demand for higher performance increases. This necessitates compact circuit designs for integration applications, along with reduced jitter and bit error rates for enhanced communication […]

Abstract Building energy systems (BESs) serve as crucial flexible resources within power systems. Among various building load types, thermostatically controlled loads (TCLs) for indoor temperature regulation are the primary contributors to flexible grid services. To harness this flexibility, it is essential to acquire a thermal dynamics model that represents temperature variations influenced by TCLs. Data-driven […]

Abstract Optimal Power Flow (OPF) problem has been studied for many years. Traditionally, this problem is solved using an iterative algorithm like the Interior Point Method (IPM). However, due to the non-convex and nonlinearity of the OPF problem, it is challenging for iterative algorithm to meet the real-time requirement of power system operation and security […]

Abstract Renewable integration in power systems causes a surge of frequency fluctuations, primarily due to the intermittent nature of renewable energy. To address this challenge, distributed energy resources (DERs) pave one promising way for frequency regulation by their aggregation as a virtual power plant (VPP). However, the technical heterogeneity of DERs results in varying frequency […]

Abstract The rapid advancement of artificial intelligence, driven by the emergence of multimodal large language models (MLLMs), is transforming the fields of computer vision and healthcare. By integrating diverse modalities, these models enable groundbreaking progress in image perception, restoration, and medical applications. This talk explores how MLLMs leverage foundational model paradigms—incorporating billions of parameters and […]

Abstract Considering the microphone is easily affected by noise and soundproof materials, the radio frequency (RF) signal is a promising candidate to recover audio as it is immune to noise and can traverse many soundproof objects. We introduce Radio2Speech, a system that uses RF signals to recover high quality speech from the loudspeaker. Radio2Speech can […]

Zoom ID: 998 6183 8733 Password: 275656 Abstract Autism Spectrum Disorder (ASD) is a neurodevelopmental condition characterized by challenges in social interaction, communication, and repetitive behaviors. Structural brain abnormalities associated with ASD are known to evolve across the developmental trajectory, making it difficult to identify consistent biomarkers for accurate individual diagnosis. In this seminar, we […]

This talk introduces strategies to address these challenges using multi-objective optimization methods that span MultiProcessor System On Chip (MPSoC), server, and application levels. Topics include the development of […]

Abstract “Be formless … shapeless, like water!”, which were the words used by Bruce Lee, as he was revealing the philosophy of Jeet Kune Do, the martial arts system Lee founded in 1967. Many parallels can be drawn in wireless communications technologies where engineers have been seeking greater flexibility in using the spectral and energy […]

Abstract This presentation will discuss converter control when power systems are operating with high (over 50%) inverter-based renewable generation.  Traditional synchronous generator controls are set to handle transient, voltage, damping, and frequency stability issues arising from contingencies.  With the anticipated retirement of many steam units and increased replacement by renewable resources and storage systems, the […]

Abstract Artificial Intelligence (AI) is transforming our world by including self-learning capabilities or extracting intriguing hidden patterns from input data. While the cloud-based computing paradigm has been a baseline approach for AI inferences in recent years, technological advances and AI optimization methods advocate a shift toward an edge-computing alternative. Nevertheless, combining cloud computing with the […]
