Earlier sources: Energy
Energy research and engineering concern how power is produced, stored, delivered, and consumed. Follow solar and nuclear power, fusion, geothermal systems, batteries, electricity grids, and changing power demand.
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 ↗732 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.

Energy Consumption and Efficiency of Autoclaves in Steaming Wooden Beams Aiming for Their Homogeneous Pigmentation ↗
A methodology for computing the heat energy consumption and efficiency of autoclaves during the steaming of wooden beams with the aim of achieving homogeneous pigmentation of the desired wood color throughout their volume is presented. The methodology includes computer simulations with two personal multi-parametric models: one to calculate the 1D non-stationary temperature distribution along the thickness of the beams during their autoclave steaming and the second to compute the heat balance of industrial autoclaves for such treatment. With the help of the first model and a new temperature–tim…

Optimizing railway energy reliability using wind energy harvester with FLC - MPPT: A case study of Addis Ababa light rail transit ↗
For sustainable railway transportation, there is need for a reliable electrification system but the Addis Ababa Light Rail Transit faces a problem of frequent power outages which compromises its operational reliability. Wind energy harvesting is a solution that has been widely adopted by different industries but the harnessing wind energy generated by moving light rail trains in addition to the ambient wind remains a complex control challenge. This study proposes a novel small-scale Wind Energy Harvesting System (WEHS) that integrates a Savonius Vertical Axis Wind Turbine (VAWT) and a Permanen…

Scenario-based optimization of battery energy storage systems in low-voltage networks with high photovoltaic penetration: A Tunisian case study using MPSO ↗
High photovoltaic (PV) penetration in low-voltage distribution networks (LVDN) introduces several operational challenges, particularly overvoltage issues and increased power losses. Conversely, excessive load demand, especially during nighttime periods, can result in voltage sags within the LVDN. To address these challenges, this paper proposes a novel simulation-based planning framework for Battery Energy Storage Systems (BESSs) applied to an IEEE 33-bus LV network. The proposed framework utilizes realistic daily load and PV generation profiles provided by the Tunisian Company of Electricity…

A Review of Pendulum Systems and Structures for Wave Energy Conversion ↗
Wave energy has emerged as a promising renewable energy source due to its high energy density and consistency compared to solar and wind. This literature review explores the technological components and design considerations of wave energy converters (WECs), focusing on primary systems, power take-off (PTO) mechanisms, and innovative concepts utilizing enclosed-hull converters based on pendulum systems and structures. Various WEC designs are analyzed with respect to their operational principles, advantages and limitations. Special attention is given to recent advances in enclosed WEC systems u…

Hierarchical Multimodal Large Language Model-Based Interpretation and Aggregation of PDP and ICE Explanations for Battery State-of-Charge Prediction in Electric Vehicles ↗
Accurate prediction of the state-of-charge (SOC) of batteries is essential for reliable energy management and safety in electric vehicles (EVs). Although machine learning (ML) models have shown strong predictive performance for SOC estimation, their practical development is hindered by limited interpretability, particularly in understanding how individual input variables affect both global model behavior and instance-level responses. Partial dependence plots (PDPs) and individual conditional expectation (ICE) plots are widely adopted visual explanation techniques. However, their interpretation…

Rule anchored graph learning improves synthetic identity fraud detection through multi relation structure rather than score level fusion ↗
Abstract Synthetic Identity Fraud (SIF), in which fraudsters combine real and fabricated information to create untraceable identities, is a fast-growing and costly problem in payment systems. Prior work treats graph neural networks as an assumed improvement over transparent rule-based identity-linkage scoring, but rarely tests where, if anywhere, that improvement originates. We build a heterogeneous Client-SSN-Email-Phone graph from a PaySim-derived identity linkage dataset (2,433 profiles, 433 fraudulent) and compare rule-based, non-graph machine learning, non-deep propagation, and deep graph…

Assessment of the Spatial Potential of the Pljevlja Municipality (Montenegro) for the Construction of Solar Power Plants Using GIS and the BWM Method ↗
This paper investigates the assessment and mapping of the spatial potential of the Pljevlja Municipality for the construction of photovoltaic solar power plants. This is of particular environmental and economic importance for this area, as it has traditionally always relied on coal exploitation. The methodological approach is based on the integration of GIS and multi-criteria analysis through the application of the Best–Worst Method. Key physical geographic and infrastructural criteria were considered: aspect and terrain slope, land use, distance from primary roads, settlements, and major wate…

Offshore Energy Infrastructure Resilience and Sustainable Energy Transition in the Baltic Sea Region ↗
Offshore renewable energy development supports Europe’s decarbonization strategy, but its contribution depends on infrastructure performance and governance. This study examines these relationships in the Baltic Sea region through a structured narrative review with targeted documentary evidence extraction. Resilience denotes the capacity to maintain, recover, and adapt essential functions under disruption. Searches of public operator, institutional and publisher resources were completed on 12 September 2026. A traceable core of 26 records, including operator notices, policy instruments, technic…

Permeability Evolution and Heat Extraction in Superhot and Supercritical Geothermal Systems: From Brittle–Ductile Mechanics to Long-Term Reservoir Performance ↗
Superhot and supercritical geothermal resources provide higher-enthalpy fluids than conventional systems. Their feasibility, however, depends on a connected flow system that survives extreme temperature, pressure, stress, and fluid chemistry. This critical narrative review evaluates field, laboratory, and numerical evidence for the creation, evolution, and management of permeability. It distinguishes superhot rock from supercritical fluid. The latter requires temperature, pressure, and composition to be evaluated together. Kakkonda and the Iceland Deep Drilling Project (IDDP) demonstrate acces…

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.
