Title From Data to Decision in Smart and Connected Communities
Speaker Nasibeh Zohrabi
Penn State Brandywine

As urbanization moves towards globalization in the next century, the evolution of smart city technologies has also brought new approaches to help communities tackle local challenges and improve city services. Technology implemented using the Internet of Things (IoT) and data analytics offers unique advantages and challenges to address important problems in a community. In addition, interdisciplinary efforts are necessary to effectively utilize emerging technologies to address a problem while considering the underlying complex social, economic, and environmental dimensions. Improving quality of life, economic competitiveness, and sustainability are the three main goals for a smart city initiative. The development of a smart city that tracks and incorporates all urban facilities and resources comes with many challenges. One of the important research challenges that the development of smart cities faces is the assurance that the data-driven management systems that control and monitor the city's operations are working in a safe, secure and reliable manner. This talk will introduce a data-driven management approach to support smart city services, applications, and infrastructures. It will also discuss the necessity of interdisciplinary efforts for providing a unique perspective as a part of a community-engaged smart city development.

She received her Ph.D. in Electrical and Computer Engineering from Mississippi State University in 2018, and her M.S. in Control and Industrial Automation from Tarbiat Modares University in 2013. Dr. Zohrabi specializes in the field of control and dynamical systems, with specific interests in cyber-physical systems (CPS), model-based control, distributed control, and stochastic hybrid systems. Her current focus is mainly on the challenges of cyber physical systems for smart cities and connected communities. She is investigating the integration of learning-based and model-based control, aiming to take advantage of both domains, for addressing challenges of complex cyber-physical systems. She is interested in wide range of applications such as smart buildings, intelligent transportation systems/smart mobility, microgrids/shipboard power systems, and renewable energy systems. She is currently working on interdisciplinary research projects for addressing different problems in community (e.g., food desert problem, opioid overdose crisis) through harnessing the power of data analytics, smart technologies, and community engagement.

Title Reconfigurable, low power, and ultra-stable hardware: A paradigm shift in IoT, cloud computing, autonomous sensing, and neuromorphic computations
Speaker Mohammad Islam
Intel Corporation

The Fourth Industrial Revolution (4IR) which trending towards automation while converging digital, physical, and biological worlds through Cyber Physical System (CPS), EDGE-AI computation, Internet of Things/Everythings (IoTs/IoEs), cloud computing, 5G/6G communication, and collective artificial intelligence (AI). As an essential generic platform of such revolution, the pervasive IoT/IoE is driving the need for fundamental innovations in myriad of applications such as sensing, ubiquitous computing that enable scalable, miniaturized, secure, low power mobile and wearable devices and/or networks. However, due to unstoppable demand of data throughput and improving efficiency of the heavily connected network (trillions of devices will be interconnected i.e., the so-called TerraSwarm) that requiring miniaturized, modular, ultra-low power, autonomous, & secured transceivers or other modules that are very impractical to implement with conventional hardware. In order to overcome such aforementioned barriers, a paradigm shift in hardware development is essential in terms of power, performance & area (PPA). Therefore, this presentation will specifically focus on the development of CloudOscillator based on MEMS-referenced ultra-stable local oscillator (LO) for reconfigurable IoT transceivers, then an application of this LO will be discussed for AI-driven low power cognitive radios (CRs). More specifically, the first part of the talk will explain design, simulation, optimization, tape out, assembly, and post-Si verification of digitally-programmable & fine-grained CMOS based novel ASICs to build LO as system-on-chip (SoC) while implementing various techniques to improve its performance such as autonomous tracking the maximum stability point (stability limit to ± 0.5 ppm, FoM=182 dB), locked to GPS steering signal for augmenting long-term stability, multi-phase coupled oscillator arrays for digital computation, & arrays of parallel oscillators for increasing power handling capability to reduce noise. Following that, an emerging trend of these LOs in HW/SW based co-designing of multi-scale neuromorphic learning machines (comprising of heterogeneous computing resources such as ASICs, a reconfigurable processor e.g. FPGA, and a conventional CPU/GPU platform), in a hierarchical architecture to facilitating energy-efficient classification tasks will be presented. After that, a low power embedded machine learning (ML) algorithm based AI-driven reconfigurable hardware platform will be discussed towards developing next generation wireless networks to achieve higher data rates and channel capacity.

In the second part of the talk, I will present a low cost, custom-built, and short range communication platform for widespread deployment of IoT while integrating a highly sensitive and multi-sensor wireless networks (WSNs) to noninvasively monitor of human physiological signals. Additionally, I will also talk on decoding and encoding of human movement activities recorded using a Deep Brain Stimulator (DBS) sensor and using innovative neural network (NN) based ensemble classifier towards developing AI-driven & intelligent DBS system for future Brain-Machine-Brain-Interfaces (BMBI). Finally, I will conclude my talk by presenting vision towards paradigm shift in low power hardware for the IoT applications and neuromorphic system.

Title Silicon Carbide Electrochemical Sensor for Glucose Detection
Speaker Kavyashree Puttananjegowda
Qorvo Inc.

This research work presents an electrospun-nanofibrous-membrane (ENFM) of silicon carbide nanoparticles (SiCNPs) with a conductive polymer (CP) for an electrochemical enzymatic glucose sensor. The surface area of a fiber matrix is a key physical property of a nanofiber membrane for enzyme binding. It is found that glucose sensing electrodes, having a SiCNPs-ENFM nanostructure, show enhanced binding of glucose oxidase (GOx) enzyme within the fibrous membrane. Morphological characterization of SiCNPs based ENFM was performed by using scanning electron microscopy (SEM) and using transmission electron microscopy (TEM) for SiC nanoparticles. The electrochemical analysis of SiCNPs-ENFM electrode was conducted by using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and chronoamperometry (CA) methods. Glucose concentration was detected at +0.6 V in a 5 mM potassium ferricyanide electrolyte. SiCNPs-ENFM based glucose electrodes show a detection range from 0.5 mM to 20 mM concentration with the sensitivity of 30.75 µA/mM cm2 and the detection limit was 0.56 µM. The lower change in current response for SiCNPs-ENFM based glucose sensing electrodes was observed for a 50 day period.
