This paper studies restricted fault diameter of the n-dimensional hypercube networks Qn (n ≥ 2). It is shown that for arbitrary two vertices x and y with the distance d in Qn and any set F with at most 2n− 3 vertices in Qn −{x, y}, if F contains neither of neighbor-sets of x and y in Qn, then the distance between x and y in Qn − F is given by D(Qn − F ;x, y)   = 1, for d = 1; ≤ d + 4, for ...

Iterated line digraphs arise naturally in designing fault tolerant systems. Diameter vulnerability measures the increase in diameter of a digraph when some of its vertices or arcs fail. Thus, the study of diameter vulnerability is a suitable approach to the fault tolerance of a network. In this article we present some upper bounds for diameter vulnerability of iterated line digraphs LkG. Our bo...

grapevine rootstocks are of the potential to increase cultivars, adaptation to different climates, soil types and a variety of unfavorable conditions. considering the existence of a rich grapevine germplasm in iran, it is possible to pick up vigorous genotypes and cultivars as drought tolerant rootstocks for commercial use due to their vast genetic potential. in this study, 698 fruitful genotyp...

shrink fit process is a useful technique in order to introduce beneficial residual stress in compound pressure vessels. in this paper, the effects of geometrical tolerances on residual stresses have been studied for a compound shrink fitted pressure vessel, practically. three layers, which are designed based on an optimum nominal thickness and overlap dimensions and tolerances, have been fitted...

BACKGROUND/AIMS Gestational diabetes mellitus (GDM) and milder gestational impaired glucose tolerance (GIGT) identify women who are at risk of developing cardiovascular disease. Endothelial dysfunction, as indicated by impaired flow-mediated dilatation (FMD) on brachial artery ultrasound, is an early marker of vascular disease. Thus, we sought to evaluate endothelial function in women with and ...

Oral administration of antigens has long been recognized as a method to prevent or delay the onset of diseases associated with untoward immune responses to self and non-self antigens. Although oral administration of antigens offers a convenient way to induce systemic tolerance, its therapeutic potential has been seriously limited by the fact that it requires repeated feeding of a large amount o...

The root is an important plant part contributing to peanut productivity underwater-limited conditions. Root volume, root surface area and root diameter may becharacters responding to pre-flowering drought (PFD) in peanut. The objectives ofthis study were to investigate the responses to PFD for root surface area, rootvolume and root diameter and to determine the inter-relationships among theresp...

The binary hypercube Qn has small diameter, but a relatively large number of links. Because of this, efforts have been made to determine the maximum number of links that can be deleted without increasing the diameter. However, the resulting networks are not vertex-symmetric. We propose a family of vertex-symmetric spanning subnetworks of Qn, whose diameter differs from that of Qn by only a smal...

The incidence of Swiss needle cast on Douglas-fir has increased significantly in recent years on the Oregon coast. Genetic variation in symptoms of disease infection, as measured by foliage traits, was assessed in two series of progeny trials to determine whether these “crown health” indicators were under genetic control and correlated with tolerance; tolerance being continued growth in the pre...
