Defensive Publications Series
This disclosure establishes a low-tech, field-expedient, manned rotary-wing aircraft (specifically a gyroplane or autogyro) optimized for rapid tactical evacuation, medical casualty transport, or emergency egress from remote, unorganized, or contested sub-arctic environments. The aircraft completely eliminates the need for advanced industrial aviation manufacturing, mechanical gearboxes, complex transmission driveshafts, or petroleum-based internal combustion. Instead, it relies on un-milled juvenile wood cores, high-tensile algae-derived carbon fibers, unrefined conifer sap resins, and calcined bio-ceramic linear alternators powered by a closed-loop, phase-changing propane cycle. This document formally places these structural and mechanical configurations into the public domain to serve as un-patentable prior art for …

An Agentic Ai System For Meeting-Centric, Time-Bounded Security Policy Enforcement, Niranjan M M
An Agentic Ai System For Meeting-Centric, Time-Bounded Security Policy Enforcement, Niranjan M M
Defensive Publications Series
Enterprises increasingly rely on meetings as the primary unit of collaboration for sensitive decision-making, training, customer engagement, and incident response. However, current firewall and network security systems remain largely static and topology-driven, forcing administrators to manually create, deploy, and later remove temporary security policies for short-lived events. This approach is operationally complex, error-prone, and does not scale in modern hybrid and highly collaborative environments.
The proposal introduces a meeting-centric, agent-driven firewall policy framework that automatically derives security intent from meeting context and participant composition. By treating the meeting identifier as the authoritative security signal, the system dynamically forms a meeting-specific …

Defensive Publications Series
A system related to context-adaptive expressive digital avatars for user interface systems. The system can dynamically modify user avatars based on environmental, temporal, and emotional signals using a Context Engine that performs sentiment analysis and collects environmental data, a Priority Engine that resolves signal conflicts using a weighted hierarchy, and a Rendering Engine that generates avatar variations through asset mapping, generative synthesis, or representative overlays. By aligning the avatar's expression with the viewing context, the system can reduce contextual mismatch and can enhance the authenticity of digital interactions.
Automated Message Resurfacing Based On Interrogative Intent Detection In Electronic Communications, Piyush Goyal
Automated Message Resurfacing Based On Interrogative Intent Detection In Electronic Communications, Piyush Goyal
Defensive Publications Series
A common issue in electronic communication is the failure to respond to messages once the unread status is removed. This often occurs when a message containing a direct inquiry is opened but not immediately addressed, causing the communication to be buried by subsequent correspondence. To address this, the disclosed technology employs on-device natural language processing to detect interrogative syntax and intent at the time a message is accessed. If a request or question is identified, a contextual interface element is displayed, allowing for a single-action commitment to follow up. At a scheduled time, the message is automatically resurfaced to the …

The Whisper Web: A Mail Intelligence Framework For Semantic Coordination In Communication Systems, Johny Manuel-Devadoss, Joanna Johnson, Jayden Jack Johnson, Deepthi Prasad
Defensive Publications Series
This paper introduces The Whisper Web, a communication intelligence framework designed for post-static digital correspondence ecosystems operating under conditions of planetary-scale coordination complexity. Unlike conventional email systems that treat messages as isolated immutable payloads exchanged between endpoints, the Whisper Web reconceptualizes communication as a continuously evolving semantic biosphere composed of dynamic probabilistic entities known as Whisper Units. Each Whisper Unit functions as a compressed socio-semantic organism capable of propagating influence through adaptive trust topologies, negotiation-energy fields, obligation gradients, institutional resonance maps, and multi-agent predictive coordination networks.
The proposed framework abandons the traditional paradigms of inboxes, message queues, folders, labels, and …

3d Puzzle Generation Beyond Voxelized Parts, Iris Xia
3d Puzzle Generation Beyond Voxelized Parts, Iris Xia
Computer Science Theses
Burr puzzles are interlocking assemblies whose pieces must be inserted and removed through tightly constrained motions. Designing them is difficult because geometric fit, interlocking behavior, and disassembly order are tightly coupled, while existing computational methods remain largely limited to voxelized or template-based constructions.
This work presents a framework for 3D puzzle generation beyond voxelized parts. The method replaces local mobility heuristics with a certified search over geometry edits. Starting from a topological contact specification, it constructs signed distance fields for individual parts, applies complementary local edits, and validates each candidate using exact geometric checks and a kernel disassembly graph. The …
A Formal Ontology Of Combat Feel, Grayson Julian Von Goetz Und Schwanenfliess
A Formal Ontology Of Combat Feel, Grayson Julian Von Goetz Und Schwanenfliess
LMU Theses and Dissertations
Combat feel, the moment-to-moment subjective character of real-time melee combat in ac- tion games, is a central concern of game design and a recurring subject in design literature, but practitioners currently navigate it through intuition and reference to admired prior work, with no shared formal vocabulary for the design trade-o!s being made. This thesis presents a decision-theoretic framework that formalizes combat feel as a Bayesian network in which designer decisions act as interventions on measurable system variables, those variables drive latent perceptual states whose conditional distributions are grounded in the psychophysics literature on input-lag detection, duration discrimination, and audiovisual temporal …
Real-Time Instruction Internalization For Large Language Models, Brenden Smith
Real-Time Instruction Internalization For Large Language Models, Brenden Smith
Theses and Dissertations
For the end user, Large Language Models (LLMs) are programs that process natural language inputs into natural language outputs. In popular usage, this tends to take the form of conversation: a user asks a question, provides information, or gives instructions, and the LLM (hopefully) replies in a manner we would expect of an informed and compliant person. While convenient and intuitive for users, this natural conversational format encourages the misconception that LLMs are learning from conversations, when they do not. This work presents the benefits and practicality of a language model paradigm that meets this user expectation -- that is, …

Patterns And Drivers Of Cladocera Community Structure In The Black Sea, Elena Bisinicu, Luminita Lazar
Turkish Journal of Zoology
Cladoceran community dynamics were examined in the Romanian sector of the Black Sea during the warm seasons of 2013– 2020, using Marine Reporting Units (MRUs) to evaluate spatial heterogeneity across transitional, coastal, and marine waters. Analyses of density, biomass, mean individual biomass (MIB), and species composition revealed interannual fluctuations superimposed on strong nearshore–offshore gradients, with higher values in transitional and coastal MRUs. The assemblage was consistently dominated by Pleopis polyphemoides and Penilia avirostris, which together accounted for most of the total abundance and biomass. Multivariate analysis identified significant differences in taxonomic composition across MRUs and years, while correlation analyses highlighted …

The Effect Of Spatial Scale Of Habitat On Abundance Of Roe Deer (Capreolus Pygargus) And Water Deer (Hydropotes Inermis Argyropus) During Summer In South Korea, Naeyoung Kim, Hyejin Kim, Hyoun-Gi Cha, Hyun-Su Hwang
Turkish Journal of Zoology
Understanding species-specific habitat preferences provides essential ecological information about interactions among habitat components. In South Korea, roe deer (Capreolus pygargus) and water deer (Hydropotes inermis argyropus) are the dominant large herbivorous mammals of the family Cervidae. The increasing populations of these species have led to ecological and economic challenges. Therefore, we investigated the effects of spatial scale characteristics on the habitat preferences of roe deer and water deer. From June to August each year between 2021 and 2023, we calculated the relative abundance index (RAI) using camera-trap data and analyzed patch characteristics in the study area using remote sensing techniques, …

Hyperspectral Image Classification Using Novel 1-D And 2-D Deep Neural Networks, Özlem Polat, Zümray Dokur, Tamer Ölmez
Hyperspectral Image Classification Using Novel 1-D And 2-D Deep Neural Networks, Özlem Polat, Zümray Dokur, Tamer Ölmez
Turkish Journal of Earth Sciences
Hyperspectral image (HSI) classification is of critical importance in many fields including agriculture, geology, environmental monitoring, and urban planning. In recent years, many researchers have utilized deep neural networks (DNNs), known for their high performance in the classification of HSIs. When 2-D/3-D convolutional neural networks are used in HSI classification, filters are applied using input patches typically larger than 11 × 11. This allows spectral and spatial features to be evaluated together. However, this combination creates several problems. Because HSIs have low spatial resolution, they often do not contain strong texture details. Furthermore, features with little relevance to classification make …

The Regionalization Of The North American Auto Industry: A Comparative Analysis Of Automotive And White Goods Trade Under Nafta And The Usmca, 1990-2024, Helen Alexandra Helfgott
Master in Public Policy Theses
This research examines whether the auto-specific provisions introduced under the North American Free Trade Agreement (NAFTA) and the US-Mexico-Canada Agreement (USMCA) have had a measurable regionalizing effect on North American export flows. The USMCA's auto-specific provisions, established in the rules of origin requirements (ROOs), increase regional value content requirements (RVC) while imposing new requirements for labor value content (LVC), steel and aluminum sourcing, and core parts. This research assesses whether these provisions are associated with a distinctive pattern of intra-regional export concentration not present in other sectors.
The study employs a descriptive comparative framework using data from UN Comtrade, spanning …
