A Hybrid Fuzzy–Support Vector Machine Framework for Real‐Time Dust Detection and Thermal Mapping in Photovoltaic Panels

Energy Science &Engineering, EarlyView.
A hybrid Fuzzy–SVM framework for real‐time dust detection and thermal mapping in PV panels. ABSTRACT Dust accumulation significantly degrades the energy output of photovoltaic (PV) panels, particularly in arid and semi‐arid regions. While existing studies have separately explored image‐based dust detection, environmental modeling, and machine learning (

Climate Change Has Already Reshaped North American Forest Pest Dynamics: Insights From Multidecadal Process‐Based Modelling

Global Change Biology Communications, EarlyView.
Climate change has rapidly expanded and shifted suitable climate conditions for eight major forest pests across North America, especially toward northern and higher elevation areas. Host exposure and overlap among pests are increasing, raising ecological and economic risks, and signaling accelerating future impacts under continued warming.

Past summer upwelling events in the Gulf of Oman derived from a coral geochemical record

Scientific Reports, 2017
We used a high-resolution oxygen isotope (δ18Ocoral), carbon isotope (δ13Ccoral) and Sr/Ca ratios measured in the skeleton of a reef-building coral, Porites sp., to reveal seasonal-scale upwelling events and their interannual variability in the Gulf of ...

Mesoscale Circulation and Coral Community Disturbance at Isolated Reefs

Global Change Biology Communications, EarlyView.
The Loop Current is a seasonally and interannually dynamic mesoscale oceanographic feature in the Gulf of Mexico that strongly influences connectivity and environmental conditions across the region. We investigated the influence of Loop Current variability on coral reef disturbances at isolated reefs in the northwest Gulf, including coral disease ...
