Artifacts Inquiry For Social Studies And Science Classrooms, Tina Valenzuela, Jaime L. Coyne

Teaching Social Studies in the Peach State

Artifacts offer opportunities for students to move beyond reading about the past to investigating evidence from it. In this article, we describe a museum-based artifact inquiry activity developed with teacher candidates and offers practical ways to adapt the activity for K–12 interdisciplinary classrooms. Beginning with a single artifact, learners make careful observations, distinguish observation from inference, develop compelling and supporting questions, investigate additional sources, construct evidence-based claims, and consider perspectives and limitations of the available evidence. The activity aligns with the College, Career, and Civic Life (C3) Framework Inquiry Arc and connects with the Georgia Standards of Excellence in social …

No New Lessons: The Impact Of World War 2 On The American Fire Service, Brady L. Hutchison

Bound Away: The Liberty Journal of History

Large loss of life fires occurred with terrifying regularity in 1940s America. While overseas, the nation’s military waged a war on tyranny and oppression abroad, at home, the country faced an enemy every bit as deadly. Tradition in the fire service has held the notion that the 1940s saw so many deadly fires due to the nation being at war. The war, it is believed, drained fire departments of manpower, dramatically increased the call volume for departments, and led departments to cut or suspend fire inspections owing to lack of manpower. With that, the consensus is that fire codes in …

H-Nare 2.0: Hybrid Numeric-Alphabetic Research Indexing Engine For Multi-Domain Open-Hardware Invention Portfolios, Michael Victor Caldwell Mr.

Defensive Publications Series

H-NARE 2.0 is a hybrid numeric-alphabetic indexing and invention-development method for large, multi-domain open-hardware portfolios. It gives each disclosure a stable numeric identifier, assigns it to one or more engineering domains, records its development status, and links related inventions, upgraded versions, shared components, and research platforms.

The method addresses a practical problem: when an inventor or research group publishes hundreds of related disclosures, readers, collaborators, and AI-assisted research tools need a reliable way to locate relevant prior disclosures, distinguish new work from corrected or upgraded versions, and identify which existing inventions can be combined into a new system.

H-NARE 2.0 …

A Read-Only Listening Companion That Shows A Tabletop Role-Playing Group's Own Campaign Notes As Names Are Spoken, Wayne Bolt

Defensive Publications Series

Long tabletop role-playing campaigns build up hundreds of invented names. General speech recognition mishears exactly these names, so looking something up during play rarely happens. This disclosure describes a read-only companion that listens to a game and shows what the group's own notes say about each name as it is spoken. Speech is turned into text on the player's own device, from the computer's sound (a video call), a microphone (a physical table), or both. Recognition can be primed with the campaign's names. The text is matched against a casebook built from the group's notes database, with entries, aliases and …

It determines system boundaries across temporal, geospatial, technological, and functional dimensions in real-time. By aligning telemetry across shift durations, batch sizes, and cycle times, it establishes a discrete time window for the residence time of a physical workpiece within a transformation node. The system may also resolve sub-facility hierarchies and select unit-operation technology profiles to capture the specific engineering physics and thermodynamic operating envelope …

Caldwell Tpms‑Fc Test Platform V1.0 An Open-Hardware, Single-Cell Pem Fuel-Cell Research Platform For Comparing Tpms Flow Fields, Graded Thermal Management, Water Management, And Net Electrical Performance, Michael Victor Caldwell Mr.

Defensive Publications Series

The Caldwell TPMS‑FC Test Platform v1.0 is an open-hardware, single-cell proton-exchange-membrane fuel-cell research platform designed to determine whether triply periodic minimal surface (TPMS) flow fields, graded thermal-management structures, vortex-conditioned air inlets, and distributed sensing improve measurable fuel-cell performance.

The platform does not claim a new fuel-cell chemistry, a new membrane, or a guaranteed efficiency breakthrough. It provides a controlled method for comparing an experimental TPMS flow field against a conventional serpentine flow field under matched hydrogen flow, air flow, temperature, humidity, pressure, and electrical-load conditions.

The prototype uses commercially available membrane-electrode assemblies, gas-diffusion layers, hydrogen and air supplies, a coolant …

Method And System For Dynamically Repositioning Virtual Content In Augmented Reality Systems During Conversations, Ashish Singh, Ahmet Cengiz Öztireli

Defensive Publications Series

Users interacting with head-wearable augmented reality (AR) devices frequently experience virtual content clutter, such as incoming notifications, application windows, or video feeds overlaying their primary field of view. When a user engages in a face-to-face social interaction while wearing head-wearable devices, this virtual content can inadvertently obstruct the user's direct line of sight to the conversation partner's face and upper body. This obstruction disrupts natural eye contact and non-verbal communication cues, creating social disconnect and distraction. Furthermore, relying on manual hand gestures to adjust or reposition virtual content is cumbersome and interrupts conversational flow.

The disclosed technology describes a conversation-aware …

Dynamic Context-Aware Safety-Optimized Routing And Emergency Infrastructure Mapping In Mobile Navigation Systems, Arti Prasad

Defensive Publications Series

This disclosure describes a system, method, and graphical user interface for context-aware safety navigation and emergency infrastructure mapping. Traditional routing engines optimize strictly for travel time or shortest spatial distance, which can route vehicles through narrow, dark, or hazardous shortcuts to save negligible amounts of time. The disclosed system addresses this by incorporating a dynamic composite safety cost function that adds safety-related penalties, such as road classification, street illumination, lane width, and pavement quality, to estimate a cost to the route. To ensure the route remains practical, a bounded maximum-estimated time of arrival (“ETA”) tradeoff engine restricts the safety-optimized path …

Atomic Settlement Of Declarative Intents Across Heterogeneous Financial Networks, Sree Sitamahalakshmi Moguluru

Defensive Publications Series

Value exchange across heterogeneous financial networks can be challenged by fragmentation, latency, and a lack of atomic settlement capabilities. A system and method are described for autonomous value settlement using a declarative, intent-based protocol that can function as an orchestration layer. A user’s desired financial outcome, for example, can be encapsulated in a cryptographically signed data object. This object may be processed by a decentralized network of competitive solver nodes that can determine a potential execution path across disparate financial networks, such as traditional banking systems and distributed ledgers. An atomic settlement engine could then coordinate the transaction using a …

Multi-Tiered System For Operational Telemetry Analysis And Governed Roadmap Reconciliation, Parnika Singhal

Defensive Publications Series

Enterprise operations can be impeded by procedural friction and unmeasured work resulting from fragmented software tools, as conventional feedback methods may lack sufficient granularity and a mechanism for accountability. A multi-tiered system is described that can identify, quantify, and analyze sources of this friction. The system could employ a context-aware telemetry engine to capture user feedback enriched with organizational data, and a semantic classification engine to categorize unstructured comments using natural language processing. The resulting structured data can be used in a closed-loop governance process to route categorized friction signals to designated owner teams. This can provide a mechanism to …

Agent-To-Map Protocol: High-Throughput Spatial Vector Streaming For Ai Agents With Double-Buffered Synchronization, Arjun Vijayvargiya

Defensive Publications Series

The agent-to-map (A2Map) Protocol streams high-frequency geospatial vector data from remote large language model (LLM) agents to interactive client viewports through a distributed architecture. A remote LLM agent generates spatial updates, which a coordinate compression engine converts into token-compact serialized representations using techniques such as variable-length ASCII polyline encoding before streaming. A client-side spatial runtime receives these incremental delta packets and applies them to an offline, double-buffered virtual map state tree. The runtime atomically commits snapshots of the state tree to a single, hardware-accelerated canvas overlay synchronized with the display’s refresh rate, achieving smooth rendering without engaging the document object …

Monocular Edge-Based Road Hazard Detection With Covariance-Weighted Spatiotemporal Clustering And Frustum Temporal Decay, Richa Gupta

Defensive Publications Series

An edge road hazard classifier processes monocular camera video to detect and localize physical road surface anomalies. The system calculates the relative distance offset of a detected hazard using inverse perspective mapping (IPM). To estimate hazard depth, the system combines structure from motion (SfM) and a monocular depth estimation network. The hazard classifier bundles these measurement values into a metadata packet for transmission to a dynamic map ingestion engine. The map ingestion engine normalizes differences in sensor noise with a spatial covariance error matrix and groups overlapping reports using spatiotemporal HDBSCAN (ST-HDBSCAN). An extended Kalman filter (EKF) synthesizes the grouped …
