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 ↗687 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.

Optimal bi-level scheduling of a PV - energy storage - charging station with consideration for EV aggregators ↗
To address the common issues of low overall operational economic efficiency, high volatility of photovoltaic (PV) output power, and insufficient local consumption capacity in PV-energy storage-charging stations during actual operation, a bi-level optimal scheduling method for station operation involving an electric vehicle (EV) aggregator is proposed. First, the EVs are clustered using the Particle Swarm Optimization-Fuzzy C-Means (PSO-FCM) algorithm, and the cluster aggregation modeling as well as constraint transformation are completed via the zonotope geometric method. Second, a bi-level op…

Context-Grounded Conceptual Design of an Environmentally Sustainable Hotel in Shiraz, Iran: Biomimicry, Voronoi Geometry, and Solar Energy Generation ↗
This study presents a context-grounded conceptual design for an environmentally sustainable hotel in Shiraz, Iran, integrating three complementary strategies: a biomimicry-inspired responsive façade, a Voronoi-based façade and landscape design, and solar energy generation. Inspired by the adaptive behavior of morning glory flowers, the responsive façade is designed to adjust dynamically to environmental conditions with the aim of improving daylight utilization and thermal performance. Voronoi patterns are incorporated into the façade and landscape with the design intent of enhancing natural li…

The State Monitoring of Energy Storage Power Stations Based on the Dynamic Local Preserving Projection–Local Outlier Factor Method ↗
Monitoring the operating status of energy storage power stations can detect battery faults in enough time to prevent them from evolving into serious accidents capable of causing economic losses or even casualties. In this paper, a novel data-driven operating status monitoring method named dynamic local preserving projection–local outlier factor (DLPP-LOF) is proposed to improve the system safety performance of energy storage power stations. First, considering that the data collected by the battery management system of the energy storage power station have temporal correlations, the collected d…

Sustainable optimization of AISI 1045 steel heat treatment using PSO-ANN, TOPSIS, MOALO algorithm for energy efficiency and hardness ↗
Abstract The study evaluates the interactive effects of quenching factors using different quenching media on hardness and on machinability energy usage of AISI 1045 steel. In conducting this research, Response Surface Methodology (RSM) Design of Experiments (DoE) was undertaken. The samples were subjected to various heat treatment conditions. When machined, hardness was measured as the primary post quench property and energy consumption was measured when dry cutting the specimens. Water quenching produced the highest surface hardness (approximately 56.7 HRC) but also the steepest hardness grad…

Energy trade across Africa and Europe: Long-term national investment and infrastructure pathways for electricity and natural gas ↗
The global energy transition is advancing under the Paris Agreement, yet progress remains fragmented across regions. Africa’s growing energy markets and abundant renewable resources, combined with Europe’s technological and financial capacity, create opportunities for closer energy cooperation. This study develops an open-source cost-optimisation model using the OSeMOSYS framework, covering forty-eight African and thirty European countries. It assesses the long-term costs and emissions impacts of electricity and natural gas trade across six scenarios, combining three levels of cross-border tra…

Mooring system analysis for a 15 MW semi-submersible floating offshore wind turbine in deep-sea deployment: Case study for Morro Bay Wind Energy Area, California ↗
Floating Offshore Wind Turbines (FOWTs) can harness high-quality wind resources at deep water sites, exemplified by the Morro Bay Wind Energy Area (WEA) in California, where depths exceed 1000 m. Such deepwater deployments present engineering challenges for reliable mooring systems that must withstand extreme, site-specific environmental conditions throughout the FOWT’s operational life. This study presents a comprehensive framework for analyzing and optimizing a 15 MW semi-submersible FOWT mooring system at the Morro Bay site. It adheres to industry standards (ABS, API, IEC, DNV) for ultimate…

MXene electrocatalysts for hydrogen evolution and methanol oxidation: Interfacial mechanisms, architectures, and emerging design principles for energy-saving electrolysis ↗
Electrochemical hydrogen production is central to renewable and sustainable energy systems, yet conventional water electrolysis remains limited by the sluggish oxygen evolution reaction, high anodic overpotentials, and associated efficiency losses. Coupling the hydrogen evolution reaction (HER) with the methanol oxidation reaction (MOR) offers an energy-saving alternative by replacing oxygen evolution with potentially value-added anodic conversion. In this context, MXenes have emerged as promising electrocatalytic platforms because their metallic conductivity, tunable surface terminations, def…

Design and Experimental Evaluation of a Spring-Supported Double-Layer Piezoelectric Energy Harvester ↗
This study presents the design and experimental evaluation of a spring-supported double-layer piezoelectric energy harvester (PEH). The proposed system was developed to improve energy harvesting performance using a double-layer piezoelectric disk configuration supported by compression springs. For comparison, a conventional single-layer PEH platform was also designed and tested under the same operating conditions. Experiments were performed under applied force levels ranging from 10 to 100 N and excitation frequencies between 0.2 and 1.4 Hz. The electrical output performance of both systems wa…

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.
