Surfaces de réponse par krigeage pour l'optimisation de formes aérodynamiques [PDF]

, 2008
Les simulations numériques RANS, utilisées en aérodynamique pour évaluer la performance d'une forme, sont coûteuses en temps de calcul. Comme une optimisation nécessite l'étude de plusieurs dizaines de formes différentes, ce coût limite le champ des ...

Bioaccessibility of Metal(loid)s From Anthropogenic Contamination in Dry Riverbed Sediments in the Cartagena–La Unión Mining District (Murcia, SE Spain): Implications for Human Health Risk Assessment

Environmental Toxicology, EarlyView.
ABSTRACT This study assessed the contamination levels, bioaccessibility, and potential health risks of As, Cd, Cu, Pb, and Zn in sediments from three dry riverbeds (El Beal‐EB, Las Matildes‐LM, and Ponce‐PN) impacted by historical mining activities in the Cartagena‐La Unión Mining District.

Artificial Intelligence in Medical Writing: A Practical and Ethical Framework for Surgical Research and Publication

World Journal of Surgery, EarlyView.
Artificial intelligence (AI) is rapidly transforming surgical research and medical publishing by changing how clinicians discover, evaluate, synthesize, and communicate scientific evidence. Despite widespread adoption, practical guidance on the responsible integration of AI into academic writing remains limited, particularly as large language models ...

Constrained optimization in simulation: a novel approach. [PDF]

This paper presents a novel heuristic for constrained optimization of random computer simulation models, in which one of the simulation outputs is selected as the objective to be minimized while the other outputs need to satisfy prespeci¯ed target values.

Changes of Potential Suitable Areas for Lynx Under Climate Change in Mohe Area, Daxing'anling Mountains, China 气候变化下中国大兴安岭漠河地区猞猁潜在适宜区的变化

Wildlife Letters, EarlyView.
Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

Using Harvest Data to Assess Factors Influencing Regional Population Declines of Muskrats (Ondatra zibethicus) 利用捕获数据评估影响麝鼠 (Ondatra zibethicus) 区域种群数量下降的相关因素

Wildlife Letters, EarlyView.
Reported annual per‐capita harvest of muskrats (PCHM) decreased as wetland complexity (total number of wetland patches) decreased in 13 state and federal wetland areas in the Midwest, USA. Our results support the hypothesis that regional‐scale declines in the abundance of muskrats are likely associated with the losses to wetland habitats throughout the

Thermo-fluid dynamic design optimization of a concentric tube heat exchanger

Journal of Fluid Science and Technology, 2019
This study proposes a shape optimization approach for the cross-sectional shape of the inner pipe of a counterflow concentric tube heat exchanger. The cross-sectional shape of the inner pipe is expressed by an algebraic expression with a small number of ...
