RESEARCH OF THE THICKNESS NOISE OF MAIN ROTOR IN FAR FIELD

open access: yesНаучный вестник МГТУ ГА, 2014
The results of acoustic characteristics of the main rotor, in particular the thickness noise are presented. The influences of geometric and kinematic parameters on the thickness noise are investigated.

Construction and Analysis of Variable Wall Thickness Profile of Double Scroll Teeth of Scroll Compressor [PDF]

open access: yesE3S Web of Conferences, 2021
Based on the changing trend of the geometric parameters of the scroll profile of the involute of circle with variable radii, a new type of double scroll teeth profile of scroll compressor composed of involute of circle with variable radii is constructed.

Separating Thickness from Geometric Thickness [PDF]

open access: yes, 2002
We show that graph-theoretic thickness and geometric thickness are not asymptotically equivalent: for every t, there exists a graph with thickness three and geometric thickness >= t.

Geometric modeling of pelvic organs with thickness

open access: yesSPIE Proceedings, 2012
Physiological changes in the spatial configuration of the internal organs in the abdomen can induce different disorders that need surgery. Following the complexity of the surgical procedure, mechanical simulations are necessary but the in vivo factor makes complicate the study of pelvic organs.

Localization of 4D gravity on pure geometrical thick branes [PDF]

open access: yesPhysical Review D, 2006
6 pages in PRD format, 3 figures, we corrected signs in the field equations, the expressions for the scalar field and the self-interacting potential. Due to the fact that no changes are introduced in the warp factor, the physics of the system remains the ...

Bounded-Degree Graphs have Arbitrarily Large Geometric Thickness [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2006
The geometric thickness of a graph $G$ is the minimum integer $k$ such that there is a straight line drawing of $G$ with its edge set partitioned into $k$ plane subgraphs. Eppstein [Separating thickness from geometric thickness. In Towards a Theory of Geometric Graphs, vol. 342 of Contemp.

A RADIAL AGE GRADIENT IN THE GEOMETRICALLY THICK DISK OF THE MILKY WAY [PDF]

open access: yesThe Astrophysical Journal, 2016
ABSTRACT In the Milky Way, the thick disk can be defined using individual stellar abundances, kinematics, or age, or geometrically, as stars high above the midplane. In nearby galaxies, where only a geometric definition can be used, thick disks appear to have large radial scale lengths, and their red colors suggest that they are ...

Analysis of Collapse Pressure Performance of Ultra-High Pressure Perforating Gun under Different Blind Hole Depths

open access: yesShiyou jixie, 2021
For the blind hole depth, outer diameter ellipticity and wall thickness unevenness that affect the collapse performance of ultra-high pressure perforating gun, an ideal geometric model and a model with geometric defects of ultra-high pressure perforating
