The more basic the environment, the more the participation of LL into the growing chain, and so an increased random structure formation to be expected.
The fatigue reliability estimation method was proposed to calculate the reliability of random structure, based on the modified first-order second-moment method and finite element method.
The proposed model presented in this study, simulates the interfacial structure of the junction between different layers as a random structure. The roughness are assumed to follow a Gaussian distribution.
Amorphous alloys are unique materials that are distinguished by their ability to retain a random structure when they solidify, in contrast to the crystalline atomic structure that forms in ordinary metals and alloys.
[18-21] have developed the orthogonal polynomial method to approximate the dynamics response of linear random structure by a series of orthogonal basis functions.
Nonsignificant coherence indicates random structure. Species occurrences in random structures are scattered along the latent environmental gradient such that measures of species turnover and range boundary clumping do not effectively reflect the concepts that they are intended to measure.
Multiaxial expansion of ePTFE materials produces a random structure of nodes and fibrils.
Throughout this paper, a random structure is always chosen uniformly at random from a given family of structures.
Unfortunately, their random structure makes metallic glasses quite brittle.
Random structure allows for the student to choose his or her own pace through the lesson, the sequence of the topics and activities, and the number of times that he or she wants to review (or return to) a topic.
Webs from aerodynamic Fehrer web forming and random carding machines are characterized by a totally random structure, isotropic strength distribution and extreme softness.
It is the resemblance between eukaryotic gene structure and the hypothetically random structure of such sequences in the "primordial soup' that makes Senapathy argue for the precedence of primordial eukaryotes.
