Hybrid Hydrodynamic‐Machine Learning Modelling for Rapid Flood Scenario Assessment: A Case Study in Aotearoa New Zealand

open access: yesJournal of Flood Risk Management, Volume 19, Issue 2, June 2026.
ABSTRACT Flooding is one of the most devastating natural disasters worldwide. It is also expected to become more severe as climate change impacts are realised. Two‐dimensional (2D) hydrodynamic models are used to obtain reliable inundation estimations.

Compressive sampling for accelerometer signals in structural health monitoring [PDF]

open access: yes, 2011
In structural health monitoring (SHM) of civil structures, data compression is often needed to reduce the cost of data transfer and storage, because of the large volumes of sensor data generated from the monitoring system.

Improving Inter‐Satellite Tropical Cyclone Precipitation Consistency by Deep Learning

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Global Precipitation Measurement mission satellite constellation comprises multiple satellites that produce widely used global tropical cyclone precipitation estimates. The quality of precipitation estimates among these satellites varies significantly due to differences in mission purpose, channel availability, and spatial resolution ...

Representation of Stratocumulus and Shallow Cumulus Cloud Fraction Near the Southeast Pacific Ocean ITCZ in ERA5 and MERRA‐2 Reanalyses

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.
Abstract Model precipitation biases in the intertropical convergence zone (ITCZ) are often tied to the underestimation of stratocumulus (Sc) and shallow cumulus (Cu) clouds. We design a method to distinguish between Sc and Cu cloud regimes under subsidence on daily timescales based on cloud top pressure and vertical velocity to investigate the spatial ...

VLSI implementation of huffman design using FPGA with a comprehensive analysis of power restrictions [PDF]

open access: yes, 2015
Lossless compression is important in Information hypothesis as well as today's IT field. Lossless design of Huffman is most to a large degree used in the compression arena.

Anti-uniform Huffman codes

open access: yesIET 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.

Global Diurnal Precipitation Cycle in the AI Model GraphCast and a 5‐km Unified Model: Challenges and Opportunities

open access: yesGeophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract This study evaluates the ability of the AI weather forecast model GraphCast to reproduce the global diurnal cycle of boreal summer precipitation, comparing it with Integrated Multi‐satellite Retrievals for GPM (IMERG) satellite observations, the ERA5 reanalysis, and an experimental global 5‐km Met Office Unified Model (UM) which is convection ...
