Guaranteeing Safe Behavior for Real-World Control Systems

• Time: 11 a.m.
• Location: Engineering Building, Room 101
• Featured Speaker: Dr. Tamas Molnar
• Abstract:
  

  Control and automation have reached the point where robotic systems and automated vehicles enter our everyday lives. In order to deploy these systems in the real world, however, strict requirements of safe operation must be met. Guaranteeing safe behavior on these systems may often be challenging, since they exhibit complicated, high-dimensional dynamics. Thus, the goal of this talk is to discuss how nonlinear control theory can be utilized to achieve provably safe behavior on real-world control systems like robotic systems and vehicles.

  In this talk, I establish a control framework that endows real-world systems with formal safety guarantees when these systems are controlled based on simplified dynamical models. I address robustness to the discrepancies between the systems and their models, including disturbances and time delays. I implement this control framework on a wide variety of systems, such as legged, wheeled and flying robots, manipulators, aerial and ground vehicles, in both simulation and experiments. This work demonstrates the potential of nonlinear control theory to provide guaranteed safe behavior in real-world applications, that ultimately facilitates the widespread deployment of safe autonomous systems.

Advanced Material Processing Techniques for Wettability Modification and Vehicle Lightweighting

• Time: 9:30 a.m.
• Location: Rhatigan Student Center, Room 262
• Featured Speaker: Avik Samanta, post doctorate research associate in the Applied Materials and Manufacturing group at Pacific Northwest National Laboratory (PNNL), Richland, Washington
• Abstract:
  

  Advanced manufacturing methods have given rise to countless applications in diverse fields, such as aerospace, vehicle technology, energy harvesting, sensing, and decarbonization. Combining multiple functionalities in a single component increases complexity in fabrication and demands innovation in material processing. This talk includes two material processing techniques to modify material properties for specific applications. The first technique consists of a fast laser-based processing method for wettability modulation by controlling the surface structures and chemistry. It leads to various extreme wettabilities, including superhydrophobicity, superhydrophilicity, superwicking, and wettability patterning. We have used the textured surface to enhance catalytic activity, anti-icing capability, and corrosion resistance. The second technique incorporates solid-state friction stir processing (FSP). This thermomechanical processing tool is applied on high-pressure die-cast (HPDC) Al-alloys. HPDC Al-alloys are increasingly used in vehicle structural components for glider weight reduction and part unitizing to achieve greater fuel efficiency and lower carbon emission. FSP-driven microstructure modification results in enhanced yield strength, ductility, fatigue life, and fracture toughness, suggesting the possible scope of lightweighting for vehicles.

Intelligent Wireless Systems: From Human Sensing to Object Detection

• Time: 10:30 a.m.
• Location: Jabara Hall, Room 260
• Featured Speaker: Yili Ren, Doctoral Candidate, Department of Computer Science, Florida State University
• Abstract:
  Recently, the prevalence of wireless devices and ubiquitous coverage of wireless networks provide us with the opportunity to extend the capabilities of wireless signals from communication to sensing humans and objects in the physical world. In this talk, I will present our work in building intelligent wireless systems that leverage a novel WiFi vision approach and deep learning to enable various human-computer interaction (HCI), Internet of Things (IoT) as well as security monitoring applications. In particular, the WiFi vision approach could generate a visualization of the signal reflections from the surrounding environment, thus providing the ability for wireless devices to "see" a person in the physical world as we humans do. Deep learning techniques are utilized to extract both spatial and temporal information in the WiFi vision to digitize the human body. Therefore, we can achieve 3D human pose estimation, 3D human mesh construction, as well as person re-identification using wireless signals. In addition, we extend human sensing to object sensing. Specifically, we design a wireless signal-based liquid level sensing system for household containers that can be easily integrated with existing smart home networks and can support various smart home applications.

Reliable Uncertainty Characterization for Space Sustainability and Safety

• Time: 10:15 a.m.
• Location: Wallace Hall, Room 209
• Featured Speaker: Smriti Nandan Paul, Ph.D., Post-Doctoral Research Fellow, West Virginia University
• Abstract: 
  Safety of the near-Earth space environment, where we have many assets like communication and reconnaissance satellites, the International Space Station (ISS), space-based optical sensors, and others, is an ever-increasing concern because of the exploding number of satellite launches. Kessler's Syndrome, or the cascading phenomenon in which space debris collisions create more debris and collisions, could make this valuable near-Earth space inaccessible. In order to protect valuable space assets, we must have good space situational awareness (SSA) and space traffic management (STM) measures in place. This seminar focuses on the topic of stochastic machine learning techniques for SSA, STM, and space weather applications in low Earth orbit (LEO). The topic will cover the effect of uncertainty in atmospheric drag parameters on orbital perturbations under various space weather conditions. Uncertainties in drag parameters are the largest sources of dynamical uncertainties for objects in the LEO region and are particularly important during geomagnetic storms. Reliable uncertainty characterization affects important SSA/STM tasks such as the sensor tasking (important for catalog maintenance and discovery of untracked space objects) and probability of collision computation (important for collision avoidance maneuvers).

Towards Autonomous Malware Deception and Orchestration Using Advanced Dynamic Malware Analysis and Data Analytics

• Time: 10:30 a.m.
• Location: Jabara Hall, 260
• Featured Speaker: Md Sajidul Islam Sajid, Research Assistant, The University of North Carolina at Charlotte
• Abstract: 
  The traditional approach to cyber defense has proven to be insufficient, as attackers have the advantage of identifying targets and launching covert attacks. While the defender must patch all system vulnerabilities, the adversary must find only one exploit to abuse. Active Cyber Deception (ACD) has emerged as effective means to reverse this asymmetry by dynamically orchestrating the cyber deception environment to mislead attackers and corrupt their decision-making process. However, creating an efficient ACD system requires human expertise and in-depth malware analysis to understand attack behaviors. Automated understanding and deployment of deception systems face several key challenges, such as advanced dynamic malware analysis that is time-intensive and resource-demanding, manual identification of malware behaviors that are not scalable, and the existing deception methods that lack agility, robustness, and automation. My research addresses these shortcomings by developing solutions that include a comprehensive dynamic malware analysis agent that performs optimal symbolic execution without running into path explosion problems, an extracting agent that extracts deception parameters and Malicious Sub-graphs (MSGs) from real-world malware and maps them to MITRE ATT&CK techniques utilizing natural language processing, an orchestration engine that provides deception as a service and orchestrates a deceptive environment at runtime utilizing API hooking and/or HoneyThings.

Improving Human Motor Learning via Neuroimaging, Neuromodulation and Machine Learning

• Time: Seminar from 3:30 to 4:30 p.m. | Students Meet With Dr. Gao from 4:30 to 5 p.m.
• Location: Woolsey Hall, Room 134
• Featured Speaker: Dr. Yuanyuan Gao
• Abstract: 
  Motor performance is essential to the daily life of humans. The improvement of fine motor skills is critical in numerous fields, such as motor rehabilitation and skill-based training, as seen in stroke patients, athletics, aviation, driving, or surgery. We aim to improve motor skills using neuroimaging to monitor, neuromodulation to intervene and machine learning to model the brain activation. First, we investigated the potential of transcranial electrical stimulation (tES) in improving bimanual surgical skills (Fig. A). We performed a series of human subject studies to explore the effects of tES on the surgical task while monitoring by functional near-infrared spectroscopy (fNIRS). We found that transcranial direct current stimulation (tDCS) improves long-term skill acquisition in decreasing surgical error. The concurrently acquired fNIRS data, while medical students performed the surgical task, elucidated a correlation between cortical activations as reported by fNIRS with tES excitation and improved performance. Second, we explored the possibility of emulating the current standardized skill assessment metrics in a surgical motor task. To achieve this, a neural network structure, Brain-NET (Fig. B), was developed to extract information from fNIRS data acquired during the task execution for potentially fast and bedside implementation. Lastly, to further solve the problem of motion artifacts induced in this surgical task, we employed the denoising autoencoder (DAE) model (Fig. C) to remove the motion artifacts. This approach improved and speeded up the fNIRS data preprocessing workflow toward enabling real-time implementation.

Fantastic Ideas and Where to Find Them: Boosting Creativity in Self-organizing Social Networks

• Time: 10:30 a.m.
• Location: Jabara Hall, Room 260
• Featured Speaker: Raiyan Abdul Baten, University of Rochester
• Abstract: 
  

  Socio-cognitive soft skills such as creativity, leadership, storytelling, debate, teamwork, and negotiation are vital for the future of work. Moreover, teams increasingly rely on online interaction platforms to navigate remote work. Elevating people’s soft skills and performance outcomes at scale, particularly in online interaction settings, is one of the aspirational challenges of our time. 

  In this talk, I will focus on creativity—the most critical soft skill of the future. In particular, I will discuss how social interactions may affect the novelty of our ideas (or the lack thereof). Through the lens of our randomized experiments, I will explain how a social network’s connections and creative outcomes co-evolve in response to its members’ ideation performance, popularity, and identity attributes. I will touch on our modeling of the empirical insights (i.e., using agent-based, game-theoretic, deep neural, and statistical network models) and the validation approaches (i.e., in a real-life academic dataset). Bringing the findings together, I will discuss how AI-, HCI-, and policy-driven solutions can help boost people’s creative performances in a social network.
