The dynamic solicitations imposed on modern production machines make the rigid body hypothesis obsolete in mechanical design.
Remark 2.1 In the case X ∗ = I (rigid solid), all hypotheses (H1 - H4) are satisfied, and the undulatory velocity field w ∗ is equal to zero.
Another set of hypotheses focus more on the non-social symptoms of autism such as rigid and repetitive behaviors, restrictive interests, and resistance to change (Leekam, Prior, & Uljarevic, 2011).
The hypothesis of rigid block is particularly suitable for historical masonry, in which stone blocks may be assumed as rigid bodies, while the hypothesis of elastic blocks may be assumed for newly constructed brickwork structures.
The displacement-based assessment procedures in standards are based on the hypothesis of rigid block, which sometimes is unable to represent their actual behaviour; furthermore, very few information is available on dissipation, which is assumed as an equivalent viscous damping, usually kept constant to 5%.
Based on this hypothesis, the rigid PolI model is schematically shown in Figure 2. Consider that the polymerase domain has just synthesized a transient flap, with the DNA substrate binding to the polymerase domain, where the polymerase active site is positioned at the fork of the flap (see DNA substrate with solid lines in Figure 2).
In this paper, 6-story and 12-story building models are studied with two different modeling approaches: the first modeling approach includes raft foundation, soil and super-structure interaction (SSI model), while the second modeling approach considers over-ground portion of building based on fixed base-rigid foundation/rigid soil hypothesis (NSSI model/fixed base model).
As a result, under some specific hypotheses (uniform loading, rigid joints, and pinned boundary), the outcomes confirmed the static efficiency.
The present work explores the hypothesis that a more rigid hydrocarbon pendant groups on a polyacrylate will improve resistance to bacterial attachment.
