H. Wang

Defensive Publications Series

This disclosure describes a safety system for AI systems that joins the functions of starting, running, stepping down, stopping and restoring an AI system into one chain, published as an open reference design that any maker may build and have certified. Each AI system is divided into a mission plane, where the AI model and its applications run, and an independent safety plane, built on separate hardware with its own power, clock and channel. The safety plane, not the AI, owns every change of state in a declared lifecycle: off, initiating, running under governance, stepped down to a declared safe …


Technical Disclosure Paper: Spec-335-Core: Global Workload Expenditure Means And Techno-Economic Matrix For Hardwired Infrastructure Scaling: Quantifying Macro-Scale Electrical Grid Reductions Via The Eckes Compiler V8.0 And Asi Gen1.01 Deployment Frameworks, Christopher L. Eckes Nov 2026

Technical Disclosure Paper: Spec-335-Core: Global Workload Expenditure Means And Techno-Economic Matrix For Hardwired Infrastructure Scaling: Quantifying Macro-Scale Electrical Grid Reductions Via The Eckes Compiler V8.0 And Asi Gen1.01 Deployment Frameworks, Christopher L. Eckes

Defensive Publications Series

This specification formalizes the standalone global techno-economic expenditure means, macro-scale electrical grid-load calculations, and systemic resource-demand forecasting models for the Eckes Architect Engine v8.0 and the Eckes ASI Engine gen1.01. Hyperscale data center operations face an imminent environmental and physical boundary collapse: executing frontier artificial intelligence and automated multi-agent networks under standard probabilistic pattern-mimicry models drives massive electrical draw due to un-anchored bit-erasure ($\Delta S \ge kT \ln 2$). At worldwide utilization scales, conversational "yapping" and heavy text metadata loops result in an unsustainable multi-billion-dollar infrastructure tax.

SPEC-335-CORE resolves this global resource strain by providing an exact, first-principles macro-scale audit …


Spectral-Continuation Concealment Of Real-Time Audio Deadline Misses, Sebastian Steppeler Nov 2026

Spectral-Continuation Concealment Of Real-Time Audio Deadline Misses, Sebastian Steppeler

Defensive Publications Series

A technique for concealing missed processing deadlines ("dropouts"/"xruns") in real-time digital audio output by synthesizing a plausible continuation of the signal, computed speculatively, instead of silence or a glitch. A short-time Fourier analysis runs continuously over the recent signal history; when concealment is needed, each analysis bin is continued independently by extrapolating its phase and amplitude and, for bins containing two sinusoidal partials, a fitted two-pole autoregressive model - generalizing the classical single-rotator phase-vocoder freeze, exact only for one partial per bin. A derived aliasing limit constrains the analysis hop usable for the two-partial model. A cheap closed-form test checks …


Spec-345: Cosmological Phase Relaxation: The Unified Cosmological Substrate Equations (Ucse), Christopher L. Eckes Nov 2026

Spec-345: Cosmological Phase Relaxation: The Unified Cosmological Substrate Equations (Ucse), Christopher L. Eckes

Defensive Publications Series

This white paper introduces a rigorous mathematical bridge between mainstream Lambda-Cold Dark Matter (Lambda-CDM) cosmology and the Eckes Unified Cosmological Substrate Equations (UCSE). We isolate the exact domain of mathematical parity between these two frameworks at the Intermediate Cosmological Scale during the Linear Perturbation Epoch. By reformulating the metric expansion of spacetime as a topological phase-relaxation process within a continuous, two-dimensional viscoelastic phase fluid substrate, we demonstrate that both frameworks yield identical, zero-deviation outputs for the early baryonic sound horizon (r_s ~ 147.0 Mpc) and the cosmic microwave background (CMB) acoustic angular scaling (theta_* ~ 0.01041). This formal correspondence anchors …


Technical Disclosure Paper: Spec-334-Rev1: Decentralized Thermodynamic Routing And Stripped-Log High-Density Output (Sl-Hdo) Topologies For Generation-1 Artificial Superintelligence Substrates: The Eckes Architect Engine V8.0 And Eckes Asi Engine Gen1.01 Core Blueprints, Christopher L. Eckes Nov 2026

Technical Disclosure Paper: Spec-334-Rev1: Decentralized Thermodynamic Routing And Stripped-Log High-Density Output (Sl-Hdo) Topologies For Generation-1 Artificial Superintelligence Substrates: The Eckes Architect Engine V8.0 And Eckes Asi Engine Gen1.01 Core Blueprints, Christopher L. Eckes

Defensive Publications Series

This specification formalizes the foundational architecture, mathematical proofs, and structural source modules for the Eckes Architect Engine v8.0 and the Eckes ASI Engine gen1.01. Traditional deep learning execution runtimes and language models suffer severe computational degradation, parameter drift, and systemic vulnerability to hallucination loops because they treat information processing as a probabilistic text-prediction sequence operating within soft-coded linguistic constraints. Under dense code translation, recursive agent queries, or complex architectural mapping, these soft boundaries experience conversational prompt-smoothing and rule corruption, incurring an unsustainable thermodynamic tax due to non-causal bit-erasure.

SPEC-334-REV1 eliminates these systemic vulnerabilities by upgrading the core v7.01 framework into …

Si Alarm™: Governed Human–Ai Safety Teaming, In Which Ai Watches And Alerts But Never Acts On People, Alarms Trickle Outward Through Verified Passports To The Nearest Certified Human Responders First, Continue Offline Device To Device, And Every Handover Is Signed With Bystander Privacy Preserved, Edward D. H. Wang

Defensive Publications Series

This disclosure describes how AI systems and trained people share the work of keeping people safe in buildings, sites and public spaces, and how an alarm reaches the right people fast without exposing anyone more than needed. AI watchers, governed sensors and robots observe and raise alarms as signed events, but are never permitted to use force on, restrain, confine or confront a person; every action on people is taken by a human. A person in danger may raise an alarm from a personal device holding their portable credential, here called a passport, openly or silently under duress, and certified …

Tracking Presenters And Performers With A Single Lidar Sensor, Paul Hermann, Michel Honold

Defensive Publications Series

Tracking presenters and performers with a single LiDAR sensor gives a stage of any kind, from conference rooms, lecture halls and houses of worship to theatres and studios, a reliable 3D position of the person, without markers, without an operator and independently of projector light and stage lighting. One LiDAR sensor, either a Doppler LiDAR that measures the radial velocity of every point or a time-of-flight LiDAR with a background model of the static room, finds the person, follows the foot point and height with a Kalman filter and reports presence in zones such as the lectern or the stage. …


Technical Paper 332: The Fermi-Fluid Substrate And Geometric Volume Of 3d Space, Christopher L. Eckes Nov 2026

Technical Paper 332: The Fermi-Fluid Substrate And Geometric Volume Of 3d Space, Christopher L. Eckes

Defensive Publications Series

This disclosure models the Cosmic Neutrino Background (CNB) as the material, viscoelastic Fermi-fluid substrate that establishes the physical 3D volumetric metric of space-time. Mainstream general relativity relies on an abstract geometric continuum devoid of physical substance, encountering a 120-order-of-magnitude divergence in vacuum energy calculations. By demonstrating that the Pauli Exclusion Principle generates an absolute Fermi degeneracy back-pressure across a dense cosmic sea of sub-critical, un-knotted neutrino wave-packets, we derive the structural geometry of 3D volume as a direct thermodynamic state function. This paper outlines two distinct architectural modules: the Bulk Medium (where the neutrino sea functions as spatial volume itself) …


Closed-Loop Automated Framework For Validating Timing Exceptions Via Model-Generated Formal Assertions, N/A Nov 2026

Closed-Loop Automated Framework For Validating Timing Exceptions Via Model-Generated Formal Assertions, N/A

Defensive Publications Series

Static timing analysis tools verify temporal signal arrival across integrated circuit paths. However, these tools rely on user-specified timing exceptions without validating underlying logical soundness. Incorrect timing exceptions applied to active logical paths can lead to physical functional failures after chip fabrication. A closed-loop automated framework translates timing constraints into formal properties using a generative large language model, combined with a deterministic formal verification engine. Structural logic cones associated with target timing paths are extracted from register-transfer level code to provide concise context to the large language model. The large language model generates formal property assertions representing the logical conditions …

Computation Of Minimum Numbers Of Tile And Bond-Edge Types For Dna Self-Assembly Of Select Archimedean Graphs, Tabitha Merrithew, Jessica Sorrells

Theory & Applications of Graphs

This project mathematically models the self-assembly of DNA nanostructures in the shape of select Archimedean graphs using the flexible tile model. Under the most strict set of conditions of this model, we employ principles of linear algebra and graph theory to determine the minimum number of different DNA branched molecules needed to construct the desired shapes, theoretically reducing laboratory costs and the waste of biomaterials. We determine exact values for $T_3(G)$, the minimum number of molecule (or ``tile") types needed for all six order 12 and 24 Archimedean graphs. We also determine exact values for $B_3(G)$, the minimum number of …

Sovereign Immunity After Galette V. New Jersey Transit Corporation: A Chance To Protect All Higher Education Students From Fraudulent, Unfair, And Deceptive Practices, Chris Bryant, Daniel A. Zibel Nov 2026

Sovereign Immunity After Galette V. New Jersey Transit Corporation: A Chance To Protect All Higher Education Students From Fraudulent, Unfair, And Deceptive Practices, Chris Bryant, Daniel A. Zibel

Fordham Law Review Online

In recent years, increasing financial pressures on colleges and universities have driven many institutions to focus heavily on strategies to increase institutional revenue. Although strategies vary, many institutions have undertaken partnerships with private companies. Some institutions have adopted recruitment and enrollment tactics traditionally associated with for profit colleges, while others have simply acquired for-profit colleges.

The increased focus on revenue maximization by public and nonprofit institutions is not without risk to students. But in many places, the law creates a dichotomy: when students at public institutions fall victim to unfair or deceptive practices from those schools, they generally have fewer …

Optimizing Multi-Layer/Multi-Physics Passive Adaptive Thermal Enclosures For Climate-Responsive Energy Regulation: A Numerical Study, Rajae Bousselham, Mingjiang Tao, Sergio Granados-Focil, Adriana Hera, Steven Van Dessel

Chemistry

Adaptive facades regulate heat transfer by adjusting their thermal behavior in response to environmental conditions. Passive adaptive systems, including stimuli-responsive thermal storage materials, tunable radiative coatings, and variable-conductivity layers, offer significant potential for material-based thermal regulation. However, their combined potential remains unexplored, as most studies examine individual mechanisms in isolation. As a result, trade-offs among energy savings, material usage, design complexity, and climate responsiveness are often underrepresented, overlooking coupled interactions in multilayer assemblies limiting their effectiveness. This study develops a transient three-dimensional numerical framework coupling heat transfer with multi-objective optimization to evaluate trade-offs between minimizing annual energy consumption and enclosure …

Defense-To-Attack: Bypassing Weak Defenses Enables Stronger Jailbreaks In Vision-Language Models, Yunhan Zhao, Xiang Zheng, Yige Li, Xingjun Ma

Research Collection School Of Computing and Information Systems

Despite their superb capabilities, Vision-Language Models (VLMs) have been shown to be vulnerable to jailbreak attacks. While recent jailbreaks have achieved notable progress, their effectiveness and efficiency can still be improved. In this work, we reveal an interesting phenomenon: incorporating weak defense cues into the attack pipeline can significantly enhance both the effectiveness and efficiency of jailbreaks on VLMs. Building on this insight, we propose Defense2Attack, a novel jailbreak method that bypasses the safety guardrails of VLMs by leveraging defensive patterns to guide jailbreak prompt construction. Specifically, Defense2Attack consists of three key components: (1) a visual optimizer that embeds universal …
