AI Agent for Hydrologic Modeling: Definition, Development, and Application

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Hydrologic modeling supports flood forecasting and water resources management, but complex preprocessing, parameterization, and configuration limit broader use. This study defines a six‐level framework for artificial intelligence (AI)‐agent autonomy in hydrologic modeling and develops a Level‐4 agent, powered by large language models, that ...

Segmented Vertex Chain Coding with Huffman Coding

, 2012
[[abstract]]To significantly decrease the amount of information while still preserving the contour shape, chain coding is widely applied to digital images analysis, especially to those raster-shaped ones.

Research on the effectiveness of noise reduction when encoding a lossless speech signal

Научно-технический вестник информационных технологий, механики и оптики
In the meantime, speech coding is one of the methods to represent the digital speech signal as in possible fewer bits value and to maintain the quality and its clearness.

A Review of Classical Lossless Data Compression Algorithmsand Their Contemporary Relevance [PDF]

Biuletyn Wojskowej Akademii Technicznej
Compression is data processing aimed at reducing the amount of information (e.g., for archiving and transfer). There is lossyand lossless compression. Compression algorithms can be either general-purpose or designed for specific types of data (e.g., for ...

3D Water Vapor Signature of Tropical Storms: GNSS Tomography of the 10 Most Severe Rainfall Events in Hong Kong 2015–2025

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract Monitoring water vapor during extreme events is crucial for understanding atmospheric physics, as well as for improving the prediction of severe weather and enhancing early warning systems. The major gap in monitoring water vapor during extreme events lies in the limited spatial and temporal resolutions of existing techniques.

Extensive but fragmented evidence limits understanding of factors shaping farmers' decisions regarding diversified farming systems: A global evidence map

People and Nature, Volume 8, Issue 7, Page 2212-2232, July 2026.
Abstract Diversified farming systems are increasingly recognised for their potential to enhance the sustainability and resilience of food systems. Yet it remains unclear whether empirical research adequately captures the drivers and constraints shaping farmers' decisions regarding diversified farming systems across stages of decision‐making ...

Determinants of Productivity and Sustainability in Small‐Scale Dairy Industries: Evidence From the Salale Zone of Oromia, Ethiopia

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Small‐scale dairy productivity in Ethiopia is significantly shaped by socio‐economic, institutional and climatic factors. Education, land ownership, infrastructure and veterinary access enhance performance, while market inefficiencies, feed costs and climate variability constrain success, underscoring the need for integrated interventions to improve ...

Anti-uniform Huffman codes

IET Communications, 2011
In this study, the authors consider the class of anti-uniform Huffman (AUH) codes. The authors derived tight lower and upper bounds on the average codeword length, entropy and redundancy of finite and infinite AUH codes in terms of the alphabet size of the source. These bounds are tighter than similar bounds.

Advancing Toward Gray Zone: Evaluation of Tropical Cyclones in Key Basins With the 12.5 km High Resolution CAS FGOALS‐f3 Model

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract State‐of‐the‐art climate models are approaching gray‐zone resolutions that can improve the representation of tropical cyclones (TCs), but the extent of these gains remains uncertain. This study evaluates the effect of spatial resolution, particularly near the gray‐zone, using three resolution configurations of the Chinese Academy of Sciences ...

Hybrid threshold adaptable quantum secret sharing scheme with reverse Huffman-Fibonacci-tree coding

, 2016
With prevalent attacks in communication, sharing a secret between communicating parties is an ongoing challenge. Moreover, it is important to integrate quantum solutions with classical secret sharing schemes with low computational cost for the real world
