Comparison of Unsteady Low- and Mid-Fidelity Propeller Aerodynamic Methods for Whirl Flutter Applications

Applied Sciences
Aircraft configurations with propellers have been drawing more attention in recent times, partly due to new propulsion concepts based on hydrogen fuel cells and electric motors.

The Role of Sediment Supply on Fish Habitat Dynamics of a Morphologically Active River Widening

River Research and Applications, EarlyView.
ABSTRACT Restoration measures, such as river widening, aim to reactivate key morphodynamic processes, which are critical drivers of fluvial habitat dynamics. While some evidence supports the important role of sediment supply on river widening's morphology, its link to fish habitat availability and dynamics remains unclear.

River Ice Processes Modelling: A Comprehensive Review

River Research and Applications, EarlyView.
ABSTRACT River ice strongly influences hydrology, hydrodynamics, and ecosystems in cold regions, with an impact on flooding, hydropower generation, navigation, and aquatic habitats. Modeling river ice processes is therefore essential for both scientific understanding and operational management.

Benefit Mechanism and Enhancement Strategy of High‐Proportion Building Photovoltaic Systems Under Carbon Reduction Constraints

IET Smart Energy Systems, EarlyView.
A benefit evaluation framework for high‐proportion building photovoltaic systems was established considering carbon reduction constraints and grid absorption costs. The study reveals the intrinsic contradiction between system‐level benefits and PV utilisation benefits, and proposes a dual‐driven optimisation pathway of effective generation and ...

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Non‐Alzheimer Aβ deposits in the human CNS: Implications with hypoxia and related conditions

Brain Pathology, EarlyView.
An Aβ deposit in a non‐Alzheimer's brain from an individual who experienced hypoxia/energy failure. Abstract We recently reported the deposition of Aβ in the frontal cortex of individuals who died of acute coronavirus disease 2019 (COVID‐19), or who did not have COVID‐19 but had respiratory distress, or infants with severe cardiac malformations.

Real‐Time Rendering of Dynamic Line Sets using Voxel Ray Tracing

Computer Graphics Forum, EarlyView.
Abstract Real‐time rendering of dynamic line sets is relevant in many visualization tasks, including unsteady flow visualization and interactive white matter reconstruction from Magnetic Resonance Imaging. High‐quality global illumination and transparency are important for conveying the spatial structure of dense line sets, yet remain difficult to ...

Steady and unsteady aerodynamics of wings

, 2021
Yukarıdaki hesaplamalar bir defa yapıldıktan sonra firar ve hücum kenarlarından atılan panellerin yeni konumlan ile baştaki denkleme tekrar dönülerek aynı yol tekrar izlenir. Bu tür bir yöntem iteratif bir teknik olmadığı için hem daha hızlı ve matris büyüklüğü daha az hem de daha kararlıdır.

Anchor Flow Maps: Efficient Sampling and Approximation of the Entire Flow Map

Computer Graphics Forum, EarlyView.
Abstract Flow maps are a fundamental concept for the visualization and analysis of time‐dependent flows. A common approach is to apply sampling and reconstruction – which comes with a number of problems: flow maps are high‐dimensional functions with locally large gradients which makes approximations very challenging.

Relics, writing, and devotion in early medieval Chelles

Early Medieval Europe, EarlyView.
The discovery in 1983 of a collection of relics with their medieval identificatory tags in the parish church of Chelles opened new avenues for research on devotional and writing practices in this Frankish royal foundation. This is the first systematic study of the corpus of relic labels that accompanied these sacred objects, particularly of the subset ...
