Title Smart Cities for Promoting the Global Sustainability
Speaker Mohammad Shahidehpour
Illinois Institute of Technology
Abstract

A smart city will offer an integrated solution for managing a region's large and interdependent infrastructures including the electricity grid, natural gas supply system, telecommunication system, urban traffic and congestion management, smart vehicles including EVs, buses and urban trains, water supply system, waste water management, urban farming, smart street lights, municipal government system including urban security (physical/; cyber) and public works. A smart city solution will enhance the efficiency of public services, meet city resident's critical needs, improve the quality of life, and promote the global sustainability. Accordingly, a smart city will be more prepared to respond to everyday challenges than a traditional monitoring system which considers a simple transactional relationship with individual citizens. A smart city is an urban development for integrating multiple information and communication technology (ICT) and Internet of things (IoT) solutions in a secure fashion. The integrated smart city solution will enhance the performance and the interactivity of urban services, reduce costs, manage resource consumptions, and will ultimately improve security, reliability, resilience and sustainability in large metropolitan regions. The integrated solution will allow smart city officials to interact directly with community members and those in charge of critical infrastructures, in order to manage what is happening in the city, how the city functions are evolving, and how the city can enable a better quality of life in normal and stressed conditions. The information gathered through the use of smart sensors that are integrated with real‐time monitoring systems is the key for mitigating inefficiencies in smart cities. The pertinent city data are collected, processed and then analyzed with the goal of improving the management of urban flows and allowing for real-time responses to unforeseen challenges. This presentation will introduce the components and the structures embedded in smart cities and discuss the benefits and the predicaments of implementing smart cities for promoting the global sustainability.

Title Inference and Control of Ensemble and Networked Systems
Speaker Shuo Linda Wang
Washington University, St. Louis
Abstract

Complex systems in which a population of dynamic units interact with each other are prevalent in nature and human society in different scales. These systems often require an appropriate excitation, an optimal hierarchical organization, or a periodic dynamical structure, such as synchrony, to function as desired or operate optimally. In many emerging applications, such as brain stimulation and quantum pulse design, the dynamics of such population systems can only be regulated by the application of a single or sparsely distributed external inputs in order to alter their state configurations or dynamic structures. This control paradigm gives rise to challenging problems regarding robust control and computation for underactuated ensembles. In this talk, I will address theoretical and computational challenges for engineering dynamic structures in ensemble and networked systems, using both model-based and data-driven perspectives. In particular, I will present an iterative method to find optimal controls for driving ensemble systems, e.g., for pattern formation. Then, I will introduce a unified data-driven method to efficiently reveal the dynamic topology and learn mathematical models of ensemble and networked systems when a reliable model is not available. I will demonstrate the robustness and applicability of these model-based and data-driven methods through practical control design and inference problems. These include the design of optimal broadband pulses in nuclear magnetic resonance (NMR) spectroscopy and imaging (MRI), and the recovery of time-varying topology of oscillatory networks for understanding functional connectivity of circadian cells or social synchronization of groups of mice. This will be followed by the discussion of related topics and future research plans.

Title Event-Driven Control of Cyber-Physical Systems with Application to Smart Cities
Speaker Xiangyu Meng
Boston University
Abstract

A cyber-physical system (CPS) is a system in which computation systems interact with physical processes. Control systems in a CPS application often include algorithms that react to sensor data by issuing control signals via actors to the physical components of the CPS. In the first part of the talk, two examples are given to demonstrate that event-triggered control outperforms traditional time-triggered control for stochastic cyber-physical systems in terms of mean-square state variations, which both having the same control cost. In the second part of the talk, some selected results on event-triggered control of multi-agent systems are presented. It is shown that consensus can be reached under asynchronous aperiodic intermittent communication between neighboring agents. Furthermore, the elapsed time between any two successive triggering instants for any pair of linked agents is lower bounded by a constant. In the third part of the talk, a hybrid system model is presented to describe the behavior of multiple agents cooperating to solve an optimal coverage problem under energy depletion and repletion constraints. The model captures the controlled switching of agents between coverage (when energy is depleted) and battery charging (when energy is replenished) modes. In the last part of the talk, smart cities are viewed as cyber-physical systems with particular application to autonomous vehicles in urban environments. An optimal speed profile is developed for autonomous vehicles approaching a traffic light without stopping.  The design objective is to achieve both short travel time and low energy consumption as well as avoid idling at a red light.

Title Systemic Risk in Networked Control Systems: Challenges & Perspectives
Speaker Christoforos Somarakis
Lehigh University
Abstract

Real-world dynamic networks operate under structural deficiencies and imperfections. Due to their importance in the fabric of the modern way of life, any failure they may experience can have severe social and economic impacts. A resilient network of communicating cyber-physical systems must be designed in the face of uncertainties and some statistical knowledge, at best, about how the real operating environment will look like. From a network analyst perspective, this implies that system design constraints may need to be envisioned in terms of safety margins instead of exact requirements. We introduce notions of risk of systemic events in interconnected dynamic systems. The risk measures are leveraged as surrogates of fragility regarding output observables of interest. Our case study regards linear multi-agent rendezvous and platooning co-ordination problems, selected as simple yet rich benchmarks for the study of autonomy in networked control systems. Our risk measures evaluate the effect of the distributed feedback laws towards stochastic disturbances and communication delays. A novel robust analysis framework is derived via the calculation of explicit bounds of tolerable safety margins, before our network defaults or fails. Furthermore, we highlight how the interplay between time- delay restrictions and noise, results in fundamental limits on risk improvement via network design methods. In addition, we argue by theory and experiment that in real-world inter-connected systems, increasing connectivity can increase the risk of systemic failure.

Title To See a World in a Grain of SAND*
Speaker Luke P. Lee
University of California Berkeley
Abstract

In this talk, I will present how to gaze at the health status of humanity and the Earth in a grain of SAND* (Speedy Analytical Nano-optofluidic Diagnostic system), and find solutions in nature for predictive medicine and preventive healthy environment. Since the future of preventive health is in the palm of our hands, a few examples of integrated optofluidic platforms will be discussed along with the vision of smart digital healthcare systems for both developing and developed countries. Rapid precision integrated molecular diagnostic systems (iMDx) is recently developed for proactive personalized medicine. The smart mobile iMDx comprises three key elements of precision medicine: (1) ultrafast multiplexed photonic PCR for the early detection of DNA and RNA biomarkers in blood and signal amplifications of protein markers, (2) a self-contained sample preparation from whole blood on chip, which allows a sample-to-answer readout platform, (3) interactive e-healthcare IT with smart analytics. Smart SANDs' rapid and accurate molecular diagnostic network for human, agricultural, and environmental health will radically improve global healthcare and empower us to create a new proactive, predictive, and preventive paradigm for enhancing global biosecurity. If time permits, I will also discuss Microphysiological Analysis Platforms (MAP), or Integrated organs on Chip (IoC), which provide physiologically relevant microenvironments and innovative non-invasive real-time molecular and physiological imaging of pathogenesis dynamics of mini-brain model for systematic neuropathogenesis, personalized drug discovery, and therapeutics.
