We study some generalized notions of cohesiveness which arise naturally in connection with effective versions of Ram-sey's Theorem. An infinite set A of natural numbers is n–cohesive (respectively, n–r–cohesive) if A is almost homogeneous for every computably enumerable (respectively, computable) 2–coloring of the n–element sets of natural numbers. (Thus the 1–cohesive and 1–r–cohesive sets coi...

Abstract Due to the lack of cohesive data in linguistics revealing how human brain functions, researchers make use various disciplines including biology, neuroscience and psycholinguistics investigate relationship between language brain. Within purview psycholinguistics, this study presupposes optimality theory Levelt’s speech production, order analyse errors committed by non-brain damaged spea...

We have established the cohesive law for interfaces between a carbon nanotube (CNT) and polymer that are not well bonded and are characterized by the van der Waals force. The tensile cohesive strength and cohesive energy are given in terms of the area density of carbon nanotube and volume density of polymer, as well as the parameters in the van der Waals force. For a CNT in an infinite polymer,...

Building on the similarities between software programs and workflow processes, this paper proposes a heuristic that offers guidance for the creation and evaluation of process designs in administrative settings. Designers can use it to select from several alternatives the process design that is strongly cohesive and weakly coupled. It is argued that such a design will result in fewer errors duri...

We calculate the cohesive energies of Fe-based glass-forming alloys in the B-Fe-Y-Zr quaternary system. Our ab-initio calculations fully relax atomic positions and lattice parameters yielding enthalpies of mixing at T=0K. We examine both the known equilibrium and metastable phases as well as a selection of plausible structures drawn from related alloy systems. This method, generally reproduces ...

It is shown that the errors of present-day exchange-correlation (XC) functionals are rather short ranged. For extended systems, the correction can therefore be evaluated by analyzing properly chosen clusters and employing highest-quality quantum chemistry methods. The XC correction rapidly approaches a universal dependence with cluster size. The method is applicable to bulk systems as well as t...

Ito, M. and G. Thierrin, Congruences, infix and cohesive prefix codes, Theoretical Computer Science 136 (1994) 471 485. A language L _~ X * is called a cohesive prefix code if xLyc~L ~ 0 implies that y = 1 and xL c L for any x, y~X*. An example of cohesive prefix codes is an infix code. We determine first the structure of cohesive prefix codes and then we study several relationships between max...

this study aims to understand certain linguistic and semantic resources for the text construction, namely the constructs of cohesion, coherence. the analysis of cohesive ties was conducted on the writing samples of 40 subjects (20 most coherent and 20 least coherent) iranian undergraduates of english. this prompted us to identify the dominant types of cohesive devices used in most coherent writ...

Cohesive zone failure models are widely used to simulate fatigue crack propagation under cyclic loadings, but the functional form of such phenomenological does not have a strong micromechanical basis. While numerical techniques been developed extract crack-tip cohesive law for monotonic fracture from experimental strain information, elucidating unloading-reloading hysteresis representing accumu...

Cohesive laws describe the resistance to incipient separation of material surfaces. A cohesive finite element is formulated on the basis of a particular cohesive law. Cohesive elements are placed at the boundary between adjacent standard volume finite elements to model fatigue damage that leads to fracture at the separation of the element boundaries per the cohesive law. In this work, a cohesiv...
