Hydro-climatic extremes: trends, anomalies and implications for urban water management

ABSTRACT Assessing the trends and anomalies of hydro-climatic extremes for improving the urban water managment. Intensifying hydrological and climatic risks are threatening infrastructures and services; therefore, understanding anomalies in hydro-climatic extremes (HCE) is impera...

HemaViT: transformer-based deep learning for automated non-invasive anemia detection using conjunctival imaging

Abstract Anemia is a common hematological disorder that requires timely diagnosis to reduce the risk of severe health complications, particularly in resource-limited healthcare settings. This study proposes HemaViT, a transformer-based deep learning framework for automated, non-i...

Data-Driven Machine Learning for Predicting Seismic Response and Fundamental Period of Masonry-Infilled Reinforced Concrete Frames

Accurate prediction of seismic response and fundamental vibration period (T) is essential for the robust seismic design of reinforced concrete moment-resisting frames, although masonry infill walls are often neglected. This study developed a hybrid machine learning framework usin...

Advanced numerical modelling of slab-subgrade interaction with uplift using an augmented Lagrangian Mortar FEM approach

Accurate representation of slab–subgrade interaction under partial contact is essential for evaluating rigid pavement response. This study develops an Augmented Lagrangian Mortar Finite Element Method (AL-MFEM) for modelling unilateral slab–subgrade contact and separation, combin...

Structural behavior and multi-objective optimization of monopile grouted connections in offshore wind turbines under early-age thermal-mechanical coupling

As offshore wind turbines scale up in harsher waters, the structural integrity of monopile foundations has become a central concern. The grouted connection between monopile and transition piece is a critical load-transfer interface, yet its behavior under early-age thermal condit...

Machine-learning projections of groundwater storage under climate, land-use, and human-driven changes in Madhesh Province, Nepal

Groundwater is the primary source of water in Madhesh Province, Nepal, yet the province lacks a reliable forecasting framework. This study develops a provincial-scale groundwater forecasting system by integrating satellite-derived groundwater storage (GWS), machine learning, and...

Recovery of AA7075 alloy and TiC-rich powder from laboratory-generated unusable AA7075/12 wt.% TiC composite using Box–Behnken design

This study investigates the recovery of AA7075 alloy and pre-existing in situ-formed TiC reinforcement from laboratory-generated, unusable AA7075/12 wt.%TiC metal matrix composite scrap. Controlled remelting experiments were designed using 17-run Box–Behnken design, and the effec...

Comparative Performance Analysis of Multi-Barrier GaN HEMTs with β-Ga2O3 Buffer and InGaN Back-Barrier Layers

A TCAD-based comparative study of AlGaN, InAlN, and quaternary InAlGaN barrier GaN HEMTs integrated with an InGaN back-barrier and β-Ga2O3 buffer layer on a SiC substrate is presented. The influence of barrier composition on carrier confinement, electrostatic behavior, and high-f...

The 2024 cascading glacial lake outburst flood in the Thame Valley of Everest region, Nepal: process, impacts and implications

Abstract. On the afternoon of 16 August 2024, a catastrophic flood devastated Thame Village in the Everest region of Nepal. This event resulted from a cascading glacial lake outburst flood (GLOF), where the outburst of an upstream glacial lake triggered the failure of a downstrea...

Experimental, finite element and machine learning based investigation of adhesive thickness on tensile strength of 3D printed PLA–CF composite lap joints

Additive manufacturing enables the fabrication of lightweight composite structures with improved mechanical performance and design flexibility. In fused deposition modelling, carbon fibre reinforced polylactic acid (PLA–CF) has attracted attention because of its higher stiffness...

Forensic geotechnical–geophysical investigation of groundwater-driven recurrent slope failure along the Kali Gandaki Road corridor, Lesser Himalayas, Nepal

Recurrent slope failures along Himalayan Road corridors cause substantial infrastructure damage and loss of life, yet systematic forensic investigation of individual failure sites remains rare in Nepal. This study presents an integrated forensic geotechnical–geophysical investiga...

Machine learning-assisted fixed-bed column adsorption of chlorpyrifos using sustainable biomass-derived activated carbon

Abstract Chlorpyrifos pollution in aquatic streams has become a serious environmental concern due to its high toxicity and adverse effects on ecosystems and human health. In this study, continuous fixed-bed column adsorption of chlorpyrifos was studied using activated carbon synt...
