SYMTRI organizes observations from public sources into a living map. Connections reflect shared subject matter; they do not establish causation or endorse a source.
Open in the map ↗720 classified signals in the fourteen-day window. Recent momentum: steady. These counts include signals awaiting readable evidence.
Earlier sources
Up to ten sources with readable evidence, ordered by their feed timestamp. These archive sources can be older than the live fourteen-day window. This list is a sample, not a measure of total activity. Dates distinguish paper publication, repository creation, model/dataset activity, Hacker News posts, and KEV catalog additions. “First archived” records when SYMTRI first stored the signal.

Plug-and-play predictive energy management for fuel-efficient platooning of gasoline-powered autonomous vehicles ↗
In this paper, we present a plug-and-play predictive energy management framework for fuel-efficient platooning of gasoline-powered autonomous vehicles. Unlike existing approaches that target electric or hybrid drivetrains, the proposed architecture addresses the nonlinear thermodynamic and aerodynamic challenges inherent to internal combustion engine (ICE) vehicles. The framework integrates an Adaptive Neuro-Fuzzy Inference System optimized via Teaching-Learning-Based Optimization (ANFIS-TLBO) with Model Predictive Control (MPC) and a Quantum-inspired Long Short-Term Memory (QLSTM) network tha…

Forecast-Driven, Energy-Based, and Degradation-Aware Energy Management for a Photovoltaic-Integrated Hybrid UPS with a Dedicated Grid Battery Charger ↗
This paper presents a forecast-plan/actual-replay energy management framework for a photovoltaic-integrated hybrid uninterruptible power supply. A day-ahead schedule is generated from forecasts and replayed using realized profiles. The formulation accounts for converter losses, LiFePO4 battery degradation, reserve requirements, and terminal stored-energy constraints. Economic comparisons require terminal inventory comparability and critical validation compliance. Ten baseline 24 h scenarios cover positive and negative prices, photovoltaic forecast error, alternative objectives, and unannounced…

Transient AC-bus voltage support for a low-voltage PV-battery shipboard microgrid under CPL-equivalent propulsion transients ↗
Photovoltaic (PV)-battery electric propulsion vessels may experience AC-bus voltage sag during rapid propulsion-power changes and renewable-power fluctuations. This study investigates transient voltage support in a scaled low-voltage shipboard microgrid using a finite-bandwidth constant-power-load (CPL)-equivalent propulsion transient. The sag of conventional Andronov–Hopf-oscillator (AHO) grid-forming control is linked to amplitude-equilibrium displacement, CPL negative incremental impedance, and the inverter/filter/feeder current-to-voltage path. A current-deviation-triggered branch is there…

Mechanically efficient disordered metamaterials: Synergistic strength and energy-absorption enhancement ↗
Disordered metamaterials exhibit excellent defect tolerance and progressive collapse energy dissipation. However, their disordered topologies lack efficient force transmission paths, creating an inherent challenge in simultaneously achieving high strength and energy-absorption capacity. To address this limitation, a stable post-buckling load-bearing reinforcement strategy based on asymmetric configurations is proposed, diverging from conventional buckling suppression strategies. Inspired by the microstructure of cuttlebone, a biomimetic disordered metamaterial system is constructed to validate…

γ‐Ray Controlled Topological Evolution of Binders for Stable and Activated Li─S Battery Cathodes ↗
ABSTRACT γ‐ray irradiation facilitates controllable, clean, and reagent‐free cross‐linking of polymer networks without side reactions. Leveraging these merits, we precisely tune the irradiation dose to engineer a three‐dimensional (3D) poly(vinyl alcohol) (PVA) binder network for lithium‐sulfur (Li─S) batteries. By integrating multiscale synchrotron radiation X‐ray characterization techniques, we elucidate how the γ‐ray irradiation dose governs the 3D network structure and consequently regulates sulfur cathode stability and sulfur reaction kinetics without using catalysts. The optimal dose of…

Intelligent Parameter Tuning Strategy for Nuclear Power Simulation Systems Based on Soft Actor–Critic ↗
The effective tuning of extensive, high-dimensional parameter sets within nuclear power simulation systems presents considerable challenges for conventional, experience-based methodologies. Such approaches often exhibit limitations including slow convergence rates, susceptibility to local optima, and inadequate adaptability across diverse scenarios. This study introduces an automated parameter tuning strategy employing the Soft Actor–Critic (SAC) reinforcement learning approach. A SAC-based agent is formulated, where state representations, action spaces, and reward functions are specifically d…

Sensitivity of Heating Energy Demand to Indoor Temperature, Effective Air-Change Rate, and Climate: A TRNSYS Case Study Supporting Sustainable Operation of a Multi-Apartment Building ↗
Building heating energy demand is influenced by indoor temperature, air exchange, and climatic conditions. This study examines the individual and combined effects of these parameters on a district-heated multi-apartment residential building in Osijek, Croatia. A TRNSYS model was evaluated using measured space-heating consumption for the analysed period from October 2024 to April 2025 and representative TMYx weather data. In the model, air exchange was represented by an effective air-change rate accounting for both uncontrolled air infiltration through the building envelope and natural ventilat…

The physical and chemical structure of Titan’s upper atmosphere: energy balance, photochemistry and Jeans escape ↗
Abstract Titan’s upper atmospheric layers provide a unique opportunity to study how photochemistry, photoionisation, haze microphysics and escape processes shape its atmospheric chemical structure, providing a unique benchmark for understanding these processes in exoplanets. Using a 1D first-principles approach, we extend the Kompot model to simulate Titan’s upper atmosphere and investigate its thermal and chemical structure, and Jeans escape. We performed self-consistent simulations of Titan’s upper atmosphere, above the dense haze layer, over a 1D radial grid by solving the coupled hydrodyna…

Hybrid-Actuated Linkage Mechanisms: Design, Control, and Energy Management ↗
Hybrid-actuated linkage mechanisms combine a main drive with a controllable auxiliary input to shape motion while distributing actuator demand. This narrative review examines mechanism design, control strategies, and energy management for presses and related cyclic machinery. The mechanisms are grouped into five-bar, seven-bar, slider-crank and differential, and application-specific configurations. The synthesis identifies trade-offs among motion programmability, dwell generation, actuator loading, and structural complexity; it does not establish a universal ranking of topologies. Control meth…

Prospects and theoretical investigation of edge isolation technology in multi-cut TOPCon solar cells ↗
Multi-cut cell technology is an effective approach to enhance photovoltaic (PV) module power, but the exposed edge significantly limits cut-cell performance due to increased perimeter-to-area ratios, i.e., more severe edge recombination. Currently, laser-assisted edge isolation (LAEI) has been proven that effectively suppresses edge recombination in half-cut cells. Here, a 3D multi-cut tunnel oxide passivated contact (TOPCon) cell model was developed in Quokka3 to systematically investigate the mechanisms and potential of LAEI. Simulations reveal that, considering only edge recombination, the…

How to assess evidence about Energy
Check each original source for its methods, release status, limitations, and supporting data. A repository announcement, a preprint, and a published study provide different kinds of evidence. SYMTRI’s subject classification helps discovery; it does not independently validate the source’s claims.
