Influence of Worm-wheel Rotational Deflection on Meshing Performance of the Cylindrical Roller Enveloping Internal Engagement Worm Gear by Song Yuanhong, Deng Xingqiao, Jiang Yuanyuan

“…The study indicates that the worm-wheel rotational deflection angle that is equal or larger than 44° has occurred undercutting,and the performance of rotation is degraded with the increase in wheel rotational angle; at the same time,performance of rotation is degraded with the increase in the curvature of the contact line on the cylindrical roller. …”

Film Cooling Effectiveness Data for Simple Injection Geometries: A Collection of Three-Axis Plots by L. D. Stone, R. J. Goldstein

“…By plotting data from several film cooling studies conducted at the University of Minnesota, the dominant roles played by density ratio, hole spacing, and surface curvature become apparent. It is also seen that a slot-plate prediction/correlation from two-dimensional film cooling studies makes an excellent standard of comparison for all film cooling studies, even though the more commonly encountered (two-axis) comparisons using standardized nondimensional parameters do not usually suggest this.…”

A finite element method for growth in biological development by Cornel M. Murea, H. G. E. Hentschel

“…We describe finite element simulations of limb growth based on Stokes flow models witha nonzero divergence representing growth due to nutrients in the early stages of limb bud development.We introduce a ''tissue pressure'' whose spatial derivatives yield the growth velocity in the limband our explicit time advancing algorithm for such tissue flows is described in detail.The limb boundary is approached by spline functions to compute the curvature andthe unit outward normal vector. At each time step, a mixed-hybrid finite element problem is solved,where the condition that the velocity is strictly normal to the limb boundary is treatedby a Lagrange multiplier technique. …”

STUDY ON FAULT DIAGNOSIS METHOD BASED ON MORLET WAVELET-SVD AND VPMCD by QI Peng, FAN YuGang, WU JianDe

“…Firstly,Morlet wavelet transform was used to pre-process the signals in the time domain to obtain a time-frequency coefficient matrix,then SVD was applied to the matrix to remove noise and extract the weak fault information in the corresponding dimensions according to the singular value curvature spectrum; Secondly,the signal components near the optimal meature were selected,and the Shannon energy entropy were used as the characteristic parameters to construct the feature vectors,which were then used to establish the fault identification model based on VPMCD. …”
