Numerical Insights Into the Resistance Reduction Mechanisms of Forward Tapered Transoms in High‐Speed Catamaran: A Computational Fluid Dynamics‐Based Study

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study investigates the hydrodynamic influence of forward transom tapering on a displacement catamaran hull using computational fluid dynamics (CFD) simulations. Five taper configurations ranging from a vertical transom base design to a fully tapered stern (1.00B) were evaluated over a wide Froude number range (Fr = .3 to 1.0).

DFT Modeling and Impedance Spectroscopy Analysis of a High Performance Zirconia‐Based Solar Cell

open access: yesNano Select, EarlyView.
p‐SnS/n‐CdS heterojunction solar cells with Al‐ZnO/i‐ZnO window layers simulated using SCAPS‐1D and impedance spectroscopy enabled tracking of solar cell parameters. The optimal performance (η = 22.76%, Voc = 0.77 V) was achieved with a 5 µm SnS absorber at Rs = 1Ω.cm−2 and Rsh = 10 kΩ.cm−2.

Robustness Assessment of Public Transport Networks in Various Graph Representations: Systematic Review, Decision Support, and Case Study

open access: yesNetworks, EarlyView.
ABSTRACT The analysis of certain properties of the underlying graph of a public transport network generates insights about the network's structure. Hereby, the choice of the graph representation depends on a trade‐off between complexity reduction and information preservation to adequately model a public transport network.

Distilling food web dynamics: top–down and bottom–up drivers of extinction and trophic cascades

open access: yesOikos, EarlyView.
Quantifying population dynamics is a fundamental challenge in ecology and evolutionary biology, particularly for species that are cryptic, microscopic, or extinct. Traditional approaches rely on continuous representations of population size, but in many cases, the precise number of individuals is unknowable.
