Rotational Surfaces Generated by Planar Curves in E3 with Density

International Journal of Analysis and Applications, 2019
In this paper, we obtain the parametric expressions of curves which have zero weighted curvature in a plane with density $e^{ax+by}$ and create the Smarandache curves of the obtaining curves. Also, we construct the rotational surfaces which are generated

3D Numerical Investigation of Surface Wettability Effects on Runback Water Flow Evolution on the Aero‑engine Rotating Spinners

Transactions of Nanjing University of Aeronautics and Astronautics
The icing of areo-engine inlet components during flight can affect engine operational safety. Conventional hot-air anti-icing systems require a large amount of bleed air， which compromises engine performance.

Does Long‐Term Lower Extremity Strength Training in Adults With Knee Osteoarthritis and Varus Alignment Reduce Knee Joint Loading During Gait?

Arthritis Care &Research, EarlyView.
Objective We examined whether 18 months of strength training in individuals with knee varus alignment and medial tibiofemoral osteoarthritis (OA) reduced knee joint loads during walking compared to an attention control group. Methods This study was a secondary analysis of a randomized clinical trial that compared the effects of strength training to a ...

Generalized Bour’s theorem

Kuwait Journal of Science, 2015
We give the classical isometric minimal helicoidal and rotational surfaces using generalizedBour’s theorem in Euclidean 3-space. Furthermore, we investigate the minimality and havesame Gauss map of the surfaces.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

On the Lightweight Potential of Laser Additive Manufactured NiTi Triply Periodic Minimal Sheet Lattices

Advanced Engineering Materials, EarlyView.
This study explores the lightweight potential of laser additive‐manufactured NiTi triply periodic minimal surface sheet lattices. It systematically investigates the effects of relative density and unit cell size on surface quality, deformation recovery, compression behavior, and energy absorption.

A molecular dynamics study on the characteristics of molecules released from tungsten plasma-facing components

Nuclear Fusion
Impurity and neutral transport processes, together with plasma–molecule interactions, affect the particle and energy influx and outflow at the plasma edge, hence influencing reactor stability and performance. These transport and interaction phenomena are,

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

Advanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Visualization of Isometric Deformations of Helicoidal CMC Surfaces

Axioms
Helicoidal surfaces of constant mean curvature were fully described by do Carmo and Dajczer. However, the obtained parameterizations are given in terms of somewhat complicated integrals, and as a consequence, not many examples of such surfaces are ...
