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 ↗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.

Lights, Camera, Attack: Exploiting Temporal HDR Fusion with Pulsed Light ↗
Modern cameras widely use temporal High Dynamic Range (HDR) to improve visibility by capturing a sequence of exposures with different integration times and fusing them into a single image. This process implicitly assumes that scene illumination remains sufficiently stable during capture. We introduce FLASH (Fusion-Level Attack by Saturating HDR), an external pulsed-light attack that deliberately attacks this assumption by creating cross-exposure inconsistency before downstream perception. FLASH exploits an algorithmic assumption rather than relying on sensor damage or hardware failure, and req…

Profiling the Energy Consumption of Serverless Functions with Joule Profiler ↗
Cloud providers and customers have widely adopted serverless computing as a convenient paradigm for deploying and executing functions on demand. To do so, serverless platforms require provisioning an appropriate execution environment before a single line of the function's code runs. These environments consist of several layers, such as container engines, hypervisors, unikernels, and programming language runtimes. While the literature has investigated the performance of these serverless platforms, it treats functions as black boxes, and the community lacks key insights into the environmental im…

Safe-by-Design Learning via Energy-based Neural Networks ↗
Learning neural-network models of dynamical systems with safety guarantees is a fundamental requirement for their deployment in safety-critical settings. Safety is commonly established by proving the invariance of a desired subset in state-space, ensuring that every trajectory initialized in this subset remains confined to it for all time under admissible inputs. Existing frameworks, however, either rely on computationally expensive post-hoc verification or employ safety-enforcing mechanisms without formal correctness guarantees. In this paper, we introduce a novel neural architecture grounded…

State Transport Routing for Short-horizon Adaptation in Multi-horizon Photovoltaic Forecasting ↗
Recent power measurements provide valuable information for photovoltaic(PV) power forecasting, but directly extrapolating short-term trends can introduce substantial errors over longer forecast horizons. To address this challenge, we propose state transport routing (STR), a lightweight adapter that refines the predictions of a frozen forecasting model. STR combines the original forecast with two complementary trajectories derived from the latest measured power level and its recent trend. A horizon-conditioned router adjusts their contributions over the first 120 min, while leaving subsequent p…

Canal-Top Photovoltaics for Supplying the Electricity Demand of a Fully Electrified Provincial Vehicle Fleet: A Case Study of Erzincan, Türkiye ↗
This study assesses whether the annual electricity demand arising from the full electrification of the existing motor vehicle fleet in Erzincan, Türkiye, could be supplied by canal-top photovoltaic (PV) systems. A provincial-scale energy-balance framework was developed by integrating official vehicle stock data, national vehicle-kilometre statistics, electric vehicle energy consumption coefficients, tractor operating assumptions, local PV generation data, module specifications, canal length information, and investment cost benchmarks. The registered road vehicle fleet, excluding tractors, was…

Techno-economic Optimization of PV-battery-diesel Systems for Reducing Diesel Use at Eleven Off-grid Telecom Sites in Niger ↗
Remote off-grid telecommunication sites in Niger depend heavily on diesel generation, leading to high fuel use, operating costs, and direct emissions. This study evaluates site-specific photovoltaic (PV)-battery-diesel retrofit configurations for eleven operational sites using measured baseline data, analytical component sizing, and hourly hybrid optimization of multiple energy resources (HOMER) Pro simulations over one year. Technical performance, generator dispatch, diesel use, lifecycle economics, sensitivity to diesel price and total capital expenditure (CAPEX), and avoided direct CO 2 emi…
Live window recorded . This is the ingestion observation time, not the publication or discovery date of each source.
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.
