Attention Based Optimization for 3D Shape Registration

Computer Graphics Forum, EarlyView.
Abstract Transformers are sequence‐to‐sequence architectures originally designed to handle structurally rigid and order‐sensitive data, such as text and images. At their core, they exploit the attention mechanism, which is permutation‐equivariant and relies on computing token‐to‐token relationships.

A Fuzzy‐Logic and Machine Learning‐Based Framework for Water Quality Index Classification in Extensive and Intensive Aquaculture Systems

Engineering Reports, Volume 8, Issue 6, June 2026.
This study presents an Internet of Things (IoT)‐to‐Cloud framework for real‐time monitoring and prediction of the Water Quality Index (WQI) across both extensive and intensive aquaculture systems. By integrating Fuzzy Logic biological thresholds with ML classification, the Random Forest model achieves over 99.5% accuracy in both environments ...

New terrace‐tile inlet technologies reduce sediment and nutrient losses

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Surface inlets such as Hickenbottom risers (HBRs) are often used to drain closed depressions and potholes across agricultural landscapes in the US Midwest. Although HBRs provide efficient drainage, they also transport substantial nutrient and sediment losses from fields.

Development of a water quality index (WQI) for the Loktak Lake in India [PDF]

Applied Water Science, 2017
Abstract The present work was carried out to assess a water quality index (WQI) of the Loktak Lake, an important wetland which has been under pressure due to the increasing anthropogenic activities. Physicochemical parameters like temperature (Tem), potential hydrogen (pH), electrical conductivity (EC), turbidity (T), dissolved oxygen (DO), total ...

Applying a Multisector Scenario Framework to Evaluate Past and Future Public Surface Water Supply Infrastructure Strategies in Texas

Earth's Future, Volume 14, Issue 5, May 2026.
Abstract Facilitating decisions over future infrastructure transitions benefits from understanding past strategies to inform future scenario development. Here, we apply a scenario‐based indicator framework to generate plausible, spatially explicit future Public Water Supply Infrastructure (PWSI) alternatives.
