Effect of Oxygen and Nitrogen Oxide Gas Concentration on Corrosion of 310N Stainless Steel in Solar Salt at 600°C

Materials and Corrosion, EarlyView.
Schematic depicting corrosion layer formation and changes in stainless steel exposed to Solar Salt at 600°C for 1000 h under different atmospheres: (a) N2 accelerates salt decomposition, producing nitrite and oxide ions, causing severe corrosion. (b) Adding O2 reduces nitrite ions formation, resulting in less corrosion than N2 alone.

Two Neighbourhood-based Approaches for the Set Covering Problem

U.Porto Journal of Engineering, 2019
The Set Covering Problem is a well-known NP-complete problem which we address in this work. Due to its combinatorial nature heuristic methods, namely neighbourhood-based meta-heuristics, were used.

Leveraging Public Transit for Robotic Deliveries: A Column Generation Approach

Naval Research Logistics (NRL), EarlyView.
ABSTRACT Autonomous mobile robots (AMRs) are small, electric, wheeled vehicles that operate at pedestrian speeds. In the last‐mile delivery service considered in this study, a fleet of AMRs is deployed across multiple recharging depots within a service area, from which they depart to perform point‐to‐point deliveries. We consider an operational setting

The importance of wild meat and freshwater fish for children's nutritional intake in the Congo Basin

People and Nature, EarlyView.
Abstract Wild meat and freshwater fish are widely consumed in the Congo Basin, but in some areas, they are at risk of disappearing due to unsustainable hunting and fishing and changes in their habitat. Wild meat is also at risk of being eliminated from local diets due to potential policy changes such as wild meat bans.

Physics‐Informed Neural Networks for Battery Degradation Prediction Under Random Walk Operations

Quality and Reliability Engineering International, EarlyView.
ABSTRACT This study addresses the challenge of predicting the state of health (SoH) and capacity degradation in Battery Energy Storage Systems (BESS) under highly variable conditions induced by frequent control adjustments. In environments where random walk behavior prevails due to stochastic control commands, conventional estimation methods often ...

Multi‐objective optimization of reservoir refill operate considering energy storage and hydrological conditions

River, EarlyView.
Abstract Optimizing reservoir refill operation rules is crucial for enhancing reservoir sustainability and resilience. This study proposes a refill operation model designed to derive optimal refill guide curves by considering flood risk prevention, maximum storage levels, and the combined benefits of hydropower generation and energy storage.

Spatial heterogeneity in basin hydrology and hydropower potential: Implications for climate resilience and economic development in Nepal

River, EarlyView.
Abstract Nepal's vast hydropower potential is central to its long‐term economic development; however, it exhibits pronounced spatial heterogeneity and is increasingly vulnerable to climate‐induced risks. This study employs an integrated, Basin‐scale analytical framework to evaluate the hydrological productivity and economic viability of major river ...
