Aesthetics of the female genitalia have come under increasing scrutiny with the popularity of Brazilian waxing trends and media promotion of sheer fashions. Women seek to have a clean and youthful appearance of the vaginal region, with minimal if any labial minora show beyond the labia majora. Labiaplasty by edge resection of the redundant labia minora tends to be the preferred method of treati...
In this paper, we design a kind of negative pressure vacuum recovery hood, arranged at the front spray gun nozzle by CFD simulation; addresses paint mist pollution problem robot spraying on outer plate ship, and is center hood. Three hood schemes are designed as follows: Scheme A, hemispherical with diameter 1.2 m; B, 1.6 C, 2.0 m. The suction holes three hoods differently. Firstly, mathematica...
Abstract The lightweight design of the hood is crucial for structural optimization an entire vehicle. However, traditional high-fidelity-based methods are time-consuming due to complex structures hood, and results heavily rely on engineering experiences. To this end, improved Adaptive Marine Predator Algorithm (AMPA) proposed solve problem. Compared original (MPA), AMPA adapts problems through ...

A small number of variants of a widely disseminated folktale is surveyed, and then analyzed in an attempt to determine how such variants can emerge while staying within the conventions of the genre. The study follows the classification of types and motifs contained in the Index of Antti Aarne and Stith Thompson. The paper's main contribution is the characterization of four kinds of type interac...
by elements of Taylor-Hood type. More specifically, for k = 2, 3, the velocity vector u is approximated in the space V k0,h = V k h ∩ H10(Ω), where V kh is the space of continuous piecewise polynomial vectors of degree ≤ k and the pressure p is approximated in the space Qk−1 h consisting of continuous piecewise polynomials of degree ≤ k−1. The stability of these pairs depends on verification of...
In this paper we show how tools based on extensions of Price’s equation allow us to look inside production-level EAs to see how selection, representation, and reproductive operators interact with each other, and how these interactions affect EA performance. With such tools it is possible to understand at a deeper level how existing EAs work as well as provide support for making better design de...
