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 ↗695 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.

Thermal management of photovoltaic panels using perforated Acp plates under outdoor conditions ↗
Abstract The operating temperature of photovoltaic (PV) modules is a key factor affecting electrical output because heat accumulation reduces voltage, power generation, and conversion efficiency. This study experimentally evaluated a passive thermal-management method using perforated aluminium composite panel (ACP) plates installed on the rear side of a 100 Wp polycrystalline PV module under outdoor conditions. Three perforation diameters, 20, 22.5, and 25 mm, were compared with an uncooled reference panel. Solar irradiance, PV surface temperature, lower-panel/ACP-plate temperature, voltage, c…

Thermal–Hydraulic and Energy–Exergy Assessment of a Solar Salt–MgO Nanofluid in a Parabolic Trough Receiver ↗
This study presents an integrated receiver-level thermal–hydraulic and energy–exergy assessment of conventional Solar Salt and a 5 wt—% MgO–Solar Salt nanofluid in a three-dimensional parabolic-trough receiver. The novelty lies in systematically determining whether the experimentally characterized thermophysical-property modifications associated with MgO addition translate into receiver-level benefits across variations in receiver length, inlet temperature, and solar-thermal loading, while simultaneously considering heat-transfer performance, hydraulic demand, exergy destruction, and entropy g…

Investigating Electro-Thermal Distribution in High-Capacity Large-Format Blade Batteries for Energy Storage ↗
Batteries are regarded as a uniform heat source in traditional thermal management system design. Inconsistencies in electrochemical reactions across time and space are often ignored, which leads to an unreasonable battery thermal management system. This paper establishes a 2D electro-thermal fully coupled model based on the Kim model and NTGK model for a high-capacity blade battery. Based on the experimental results, the accuracy of the model was verified by examining terminal voltage, average battery temperature, and temperature distribution. The distribution characteristics of physical field…

Sensor-Rich Robotic Grasping in Unstructured Scenes: A Review of Vision, Multimodal Fusion, Learning Architectures, and Closed-Loop Manipulation ↗
Vision-based robotic grasping is a core capability for autonomous manipulation, yet reliable operation in unstructured scenes remains difficult because sensing, representation, contact mechanics, control, and hardware are tightly coupled. This structured qualitative review examines a 117-publication corpus spanning grasp detection and pose estimation, multimodal and tactile sensing, learning architectures, closed-loop correction, active interaction, and deployment-oriented evaluation. The update began with 91 candidate records; DOI and normalized-title deduplication produced 83 unique records,…

Comparison of Building Energy Performance Policies in the European Union and Türkiye in the Context of Climate Risk Management ↗
Due to its significant contribution to global energy consumption and greenhouse gas emissions, the building sector plays an important role in reducing carbon footprints, supporting climate adaptation, and strengthening risk management. This study compares building energy performance policies in the European Union (EU) and Türkiye from the perspective of climate risk management. The analysis focuses on the EU Energy Performance of Buildings Directive (EPBD), which has developed from the nearly zero-energy building (nZEB) approach toward the zero-emission building (ZEB) target, and on Türkiye’s…

Energy-dependent underwater abrasion behavior of sustainable lightweight concrete incorporating agro-waste aggregates and natural fibers under rotational hydraulic conditions ↗
Abstract Lightweight aggregate concrete has become a popular material in hydraulic engineering and coastal and offshore engineering, and understanding its durability under underwater rotational abrasion is critical. Comparative studies on the abrasion resistance of several agricultural waste aggregates under high-energy underwater conditions have been conducted for the production of sustainable concrete; however, such studies are still scarce, especially considering the combined effects of rotational speed, abrasion time, aggregate properties, and properties of the interfacial transition zone…

A new method for calculating the weak source startup of reactor based on Monte Carlo method ↗
Weak source startup represents a reactor startup regime in which neutron population evolution is dominated by stochastic effects and cannot be adequately described using conventional deterministic or point-kinetics approaches. The weak source startup approach, which operates without an external neutron source, eliminates the need for costly neutron source procurement and improves the economic performance of nuclear power plants. In this study, a Monte Carlo based method is developed for simulating weak source startup processes. The proposed approach enables direct time-dependent simulation of…

Visual–frequency bimodal fusion networks for oscillation detection and quantification in industrial control loops ↗
Oscillations arising from performance degradation in industrial control loops threaten operational safety and efficiency. Existing automated detection methods often rely on fixed assumptions and single-modality signals, limiting their robustness and generalization. In this work, we propose a visual–frequency bimodal fusion network (VFBFN) for oscillation detection and quantification. VFBFN employs a dual-branch encoder consisting of a two-dimensional (2D) convolutional neural network (CNN) for image-based signal embeddings and a one-dimensional (1D) CNN for frequency spectra to extract complem…

A Review of Energy-Efficient Routing Protocols for Underwater Acoustic Wireless Sensor Networks ↗
Underwater acoustic sensor networks (UASNs) are key enabling technology for the Internet of Underwater Things (IoUT), supporting environmental monitoring, offshore exploration, disaster warning and surveillance. Existing routing approaches include depth- and hop-by-hop schemes, geographic/vector-based forwarding, clustering, opportunistic and cross-layer routing, and more recent reinforcement-learning and multi-modal designs. Depth-based methods are simple and localization-free but can create redundant forwarding and energy hotspots near sinks; geographic methods provide directional forwarding…

Adaptive threshold optimization for efficient and robust high-dimensional sensor calibration in building energy systems ↗
With the rapid advancement of artificial intelligence and big data technologies, high-quality data have become increasingly essential for effective building energy system management. High-dimensional in-situ calibration provides a promising way to correct sensor biases in building energy systems without relying on physical reference sensors. However, practical applications face significant challenges due to random measurement noise and the computational burden of high-dimensional data. To address these issues, this study proposes a sensor in-situ calibration framework integrated with Bayesian…

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.
