The aerodynamic design and optimization of a wing-fuselage junction fillet as part of a multi-disciplinary optimization process during the early aircraft design stages [PDF]
, 1996 An attempt to minimize interference drag in a wing-fuselage junction by means of inserting a fillet is presented in this thesis. The case of a low-wing com- mercial transport aicraft at cruise conditions is examined.

Additively Manufactured Scaffolds with Optimized Thickness Based on Triply Periodic Minimal Surface
Materials, 2022 Triply periodic minimal surfaces (TPMS) became an effective method to design porous scaffolds in recent years due to their superior mechanical and other engineering properties. Since the advent of additive manufacturing (AM), different TPMS-based scaffolds are designed and fabricated for a wide range of applications.

Optimal boundary regularity for minimal surfaces with a free boundary
Manuscripta Mathematica, 1981 Let x(w), w=u+iv ∈ B, be a minimal surface in ℝ3 which is bounded by a configuration 〈Γ, S〉 consisting of an arc Γ and of a surface S with boundary. Suppose also that x(w) is area minimizing with respect to 〈Γ, S〉. Under appropriate regularity assumptions on Γ and S, we can prove that the first derivatives of x(u, v) are Holder continuous with the ...
