Different Decomposition Strategies to Solve Stochastic Hydrothermal Unit Commitment Problems [PDF]

, 2017
Solving very-large-scale optimization problems frequently require to decompose them in smaller subproblems, that are iteratively solved to produce useful information. One such approach is the Lagrangian Relaxation (LR), a broad range technique that leads

From Rainfall to Rumors: Interpreting the 2024 Bangladesh Floods Through Numbers, Narratives, and Information Gaps

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract When severe floods struck southeastern Bangladesh in August 2024, competing explanations emerged. Meteorological analysis revealed that extreme precipitation was exacerbated by the Madden‐Julian Oscillation and jet stream dynamics. However, alternative narratives proliferated on social media, particularly claims that India deliberately ...

Hidden Complexity in Reservoir Flow Regulation Revealed by Spectral Analysis

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Understanding reservoir regulation of streamflow is critical for hydrological modeling and ecohydrological assessments, yet our knowledge of how reservoirs preferentially modify flow variability remains limited. Here we apply spectral analysis to daily inflow‐outflow data from 205 US reservoirs, decomposing regulation effects into operational ...

Impacts of Extreme Events on Community Livelihoods: El Niño Effects and Management of Seaweed Farms in the South Coast of Kenya

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Seaweed farming affected by El Nino event, needs policy, data and value‐added documents ABSTRACT Seaweed farming is a vital economic activity for coastal communities in the Western Indian Ocean, with growing potential in food, bio‐stimulants, pharmaceuticals and environmental management. Some farmed species, such asEucheuma denticulatum and Kappaphycus

From Disruption to Stabilization: A Functional Governance Perspective on the Renewable Energy Transition in Montenegro

Environmental Policy and Governance, Volume 36, Issue 2, Page 385-402, April 2026.
ABSTRACT As global climate ambitions intensify, the key challenge lies not in setting renewable energy targets but in designing governance systems that can translate them into lasting transformation. The transition management literature has advanced a valuable research agenda for initiating change through niche innovations and participatory arenas in ...

Power Losses in Energy Generation: Mechanisms, Mitigation Strategies, and Pathways to a Sustainable Future

Energy Technology, Volume 14, Issue 4, April 2026.
This article provides a comprehensive review of loss mechanisms in the generation stage of energy systems, covering fossil, nuclear, and renewable technologies. It examines their environmental and operational implications and shows how overlooking generation losses distorts efficiency assessments.

Seismic Design of Concrete Dams: An Integrated Risk‐Informed Performance‐Based (RIPB) Framework

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 5, Page 1019-1049, 25 April 2026.
ABSTRACT This paper advances the integration of risk‐informed principles into the seismic design of dams—a domain long guided by standards‐based, largely deterministic approaches. While performance‐based earthquake engineering is well established for buildings and bridges, its systematic adoption in dam engineering remains limited. We first address two
