Topic: Multi-Modality Sensing and Communications for Connected Vehicles Location: Lester W. Cory Conference Room, Science & Engineering Building (SENG), Room 213A Zoom Conference Link: https://umassd.zoom.us/j/92374869463 Meeting ID: 923 7486 9463 Passcode: 174802 Abstract: Connected and autonomous vehicles (CAVs) are set to transform intelligent transportation systems by enhancing safety, traffic efficiency, and mobility. Key use cases require high throughput, low latency, reliable communication, and precise positioning. The millimeter-wave (mmWave) band offers a broad spectrum to meet these demands but suffers from high path attenuation, necessitating beamforming techniques that use large antenna arrays to create narrow beams for better signal strength. Traditional beam alignment methods based on exhaustive searching can result in significant computational and communication overhead, making them unsuitable for dynamic vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) scenarios. This proposal outlines background information, problem statements, and the challenges of deploying mmWave communications in CAV use cases. It includes two preliminary solutions that utilize deep learning techniques, leveraging single and multi-modality sensing data to predict optimal beams for strong mmWave links. Real-world testing indicates that these methods significantly reduce the beam searching time and overhead compared to conventional approaches, representing a promising advancement in mmWave communication. The proposal concludes with suggested future directions for research.

However, further research is essential to clarify the complex interplay among these affective factors of early development. This includes pinpointing the contexts in which children's fearfulness is enacted and exploring specific types of emotion knowledge deficits that might be at play. A sample of 74 preschoolers participated in this study on emotion and internalizing behaviors. The study introduced a novel measure of children's fear expressed during non-fearful contexts (context-incongruent fear), and an unexplored assessment of sad and fearful narratives to a picture book. To clarify the contribution of children's processing of emotional contexts, knowledge of negative emotional situations was also assessed. Parents and teachers reported on children's internalizing behavior. Hypotheses predicted context-incongruent fear would be associated with less knowledge of negative emotions, more fearful and sad narratives, and greater internalizing behaviors. Hypotheses also predicted that less knowledge of negative emotion and more fearful and sad narratives would be associated with internalizing behaviors. It was also expected that context-incongruent fear would moderate the association between emotion knowledge and internalizing behavior, such that context-incongruent fear would strengthen the association. Likewise, I expected that context-incongruent fear would moderate the association between sad and fearful narratives and internalizing behavior, but context-incongruent fear would strengthen the association. Finally, a model that incorporated all study factors proposed that the association between emotion knowledge and internalizing behavior would be mediated by fearful and sad narratives, but that this mediation would be more likely in children who showed higher levels of context-incongruent fear. As expected, children's context-incongruent fear and understanding of negative emotion contexts were predictive of internalizing behavior. Additionally, although children who made fearful and sad narratives to the picture-book had greater internalizing behaviors, this was more likely for children who had greater knowledge of negative emotional situations. These findings suggest understanding of negative situations may transpire into negative expressions in everyday situations that promote internalizing behaviors. Additionally, they highlight the interplay between children's understanding of emotional context and the narratives they project onto them with relevance to their emotional well-being.

Topic: A Heterogeneous Multi-Agent Colluding Attack Defense System Location: Lester W. Cory Conference Room, Science & Engineering Building (SENG), Room 213A Zoom Conference Link: https://umassd.zoom.us/j/99742168771 Meeting ID: 997 4216 8771 Passcode: 976327 Abstract: The voting-based replication mechanism is widely used as a fault-tolerant technique across various engineering and computing domains. However, this technique is vulnerable to colluding attacks where multiple malicious resources can collaborate to produce identical wrong results to potentially fail a task execution, posing significant threats to system integrity, performance, and reliability. This research introduces a heterogeneous multi-agent colluding attack defense system, a novel credibility-based framework designed to detect and mitigate the impact of coordinated adversarial behavior within diverse agent environments. The proposed framework employs a dual-role architecture, consisting primarily of spotter and resource agents. Spotters are responsible for monitoring and evaluating the credibility of resource agents based on their performance and voting patterns. Resource agents that fail the spotter's check are excluded from task execution. The system dynamically and optimally allocates these roles under users' predefined cost constraints, balancing resource utilization and defense efficiency. By strategically adjusting the credibility scores of resource agents, the proposed defense mechanism adapts to ensure sustained system performance and reliability. Experimental studies are conducted to demonstrate the effectiveness of the proposed heterogeneous multi-agent system in defending against colluding attacks in voting-based computing environments. The impacts of several key model parameters on the system reliability are also investigated.
