Details
The Department of Electrical and Computer Engineering within the College of Engineering is hosting Dr. Maciej Zawodniok, an associate professor from Missouri University of Science and Technology, from 5:30 to 7 p.m. Thursday, Mar. 30 in 323 Woolsey Hall. Zawodniok will present "Cradle-to-Grave Digital Thread—Challenges and Solutions" to students, staff, faculty and industry partners. Pizza will be served.

Abstract
Modern manufacturing industry increasingly depends on digital domain for delivering high quality, economically viable, and technologically advanced products. Moreover, for safety critical applications, for example aircraft construction and maintenance, both the components and the manufacturing process must meet high quality requirements with appropriate documentation. Digital Thread refers to process of collection and processing of such data, whereas a particular component digital data portfolio is called a Digital Twin. There are many anticipated benefits of using Digital Thread and Digital Twin including: (a) automation of data collection, (b) ability to analyze and optimize manufacturing processes, (c) reduce time-consuming and costly certifications of processes and parts, (d) actual, individualized part usage history, tracking, and maintenance, (e) ability to refurbish or build individual replacement component that is no longer mas-produced, etc.

However, there are also many challenges that need to be addressed to realize these benefits. The challenges developing new technologies including tracking of components throughout the manufacturing and supply chains, distributed data storage and management, linking data items from various manufacturing stages into one, complete digital twin. In this talk, the overview of the Digital Thread framework is discussed in context of potential use cases and challenges. Also, the solutions for automated data collection and component localization and tracking will be presented including edge-device (LIMS Box) and passive RFID based tracking and 3D localization technique.

Biography
Dr. Maciej Zawodniok is an Associate Professor, Missouri University of Science and Technology (2014-Present). Dr. Zawodniok received PhD in Computer Engineering, Missouri University of Science and Technology in 2006. He has been awarded a prestigious NSF CAREER award on enhancing performance of Radio Frequency Identification (RFID) based network. He co-authored over 30 journal publications, two book chapters, and over 35 conferences. He is Senior Member of IEEE. He has graduated 8 PhD and 13 MS students. Currently he is leading projects on cyber-infrastructure for digital manufacturing and sensor fusion for air traffic control. He is participating in development of an RFID-based maintenance system. He was a lead investigator of an Embedded Systems and Networking Thrust in the ARL funded LoTrExWiSeNet project with a focus on localization and embedded sensing platform. Dr. Zawodniok has implemented control schemes for various real-time systems including embedded firmware for robot-supported inspection of aircraft components for Boeing Co., HVAC system controller for Verde GSE company. Moreover, he published multiple papers on developing communication schemes and protocols for sensor and control systems. His work on design and analysis of resilient, networked control system utilizes statistical analysis to prove guarantee of convergence and performance in the presence of stochastic communication network.
