&lt;p>STRATOS develops a cloud-native, model-agnostic security middleware for protecting AI models used in time-critical scientific and energy-system operations. AI is increasingly embedded in workflows such as grid forecasting, contingency analysis, and operational decision making, creating new risks from adversarial perturbations, inference-time evasion, and backdoor attacks that may remain physically plausible while corrupting model outputs. STRATOS addresses this problem through a physics-grounded DevSecOps architecture that continuously evaluates inference streams, computes certified trust scores, and distinguishes malicious manipulation from legitimate operational variability without requiring modification of the protected model.&lt;/p>
&lt;p>The project combines physics-constrained adversarial emulation, imbalance-resilient certified detection, and a multi-tier runtime mitigation pipeline that includes targeted input purification, Control Barrier Function-based graceful degradation, and quarantine or rollback of compromised data and models. The Phase I system will be evaluated across the University of Hawaiʻi at Mānoa campus microgrid and Argonne National Laboratory&amp;rsquo;s Controller-Hardware-in-the-Loop platform, targeting at least 90% certified detection, no more than 5% false positives, at least 95% interception of synthesized adversarial payloads, and end-to-end latency of 20 ms or less. The longer-term goal is to transition STRATOS toward a federated security architecture for trustworthy AI across DOE scientific computing and critical-infrastructure environments.&lt;/p></description></item><item><title>RASRE: Reflectarray and Applications in Smart Radio Environment</title><link>https://gustybear.github.io/projects/vip_reflectarray_and_applications/</link><pubDate>Tue, 10 Dec 2024 00:00:00 -1000</pubDate><guid>https://gustybear.github.io/projects/vip_reflectarray_and_applications/</guid><description>&lt;hr>
&lt;h1 id="executive-summary">Executive Summary&lt;/h1>
&lt;p>Reflectarray present a paradigm shift in wireless communication and sensing in mmWave and sub-THz region by offering unprecedented control over the propagation environment. Traditional wireless systems are largely at the mercy of the channel, which can be severely impaired by obstacles, fading, and interference. Reflectarray, however, introduce a new degree of freedom by enabling programmable manipulation of the wireless channel. Through precise control of the reflection and refraction properties of an array of elements, reflectarray can be used to mitigate path loss, combat fading, null interference, and shape radiation patterns, which can be used to enhancing spectral efficiency, energy efficiency, and expanding coverage. This project aims to investigate the fundamental principles of reflectarray operation, develop novel reflectarray architectures and control algorithms, and explore their applications in a wide range of wireless communication, sensing, energy transfer, and security scenarios.&lt;/p>
