Previous work has demonstrated a difference in human sensitivity to compressive and shearing speed gradients. This raises the possibility that the ability to estimate the slant of a surface may vary with its direction of tilt. No such variance was found here, which may indicate that slant estimation depends upon deformation rather than upon compression or shear.

Ductile failure prediction is essential to avoid loss of structural integrity or control crack propagation during forming processes. One the main difficulties complex paths. This study proposes a nonlocal extension local Gurson–Tvergaard–Needleman (GTN) ductile damage model at finite strains able capture cup–cone slant fracture. The proposed based on an implicit gradient formulation which enabl...

To further investigate the fracture response in propellant grain, numerical methodology is proposed to cope with crack propagation simulation especially for mixed mode condition. The discrete scheme of linear viscoelastic constitutive model proposed, which provides a key means propagation. In order simulate cohesive traction distribution on new surface, extrinsic Park-Paulino-Roesler (PPR) zone...

Several individual differences including age have been suggested to affect the perception of slant. A cross-sectional study of outdoor hill estimation (N = 106) was analyzed using individual difference measures of age, experiential knowledge, fitness, personality traits, and sex. Of particular note, it was found that for participants who reported any experiential knowledge about slant, estimate...

People judged the inclination of hills viewed either out-of-doors or in a computer-simulated virtual environment. Angle judgments were obtained by having people (1) provide verbal estimates, (2) adjust a representation of the hill's cross-section, and (3) adjust a tilt board with their unseen hand. Geographical slant was greatly overestimated according to the first two measures, but not the thi...

This study looks into the bislant submanifolds of almost product semi-Riemannian manifolds that are Riemannian, and lightlike. We also state theorems provide required conditions for constructing a slant submanifold from submanifold. Morever, we define semi-slant locally discuss integrability distributions invariants or slants constitute

Antennas which are fed by a “shunt” or other method in which a part of the antenna comprises a portion of an electrically small one-turn loop, so that the feed is in essence a sort of autotransformer, are quite common, particularly at frequencies above 10 megahertz. Shunt feed arrangements for grounded vertical tower radiators, such as those used for medium wave broadcasting, are less common. A...

modelling of crack propagation by finite element method under mixed mode conditions is of prime importance in fracture mechanics. this paper describes an application of finite element method to the analysis of mixed mode crack growth in linear elastic fracture mechanics. crack growth process is simulated by an incremental crack-extension analysis based on the maximum principal stress criterion,...

OBJECTIVES HIV prevalence among people who inject drugs (PWID) in Ottawa is estimated at about 10%. The successful integration of peers into outreach efforts and wider access to HIV point-of-care testing (POCT) create opportunities to explore the role of peers in providing HIV testing. The PROUD study, in partnership with Ottawa Public Health (OPH), sought to develop a model for community-based...
