Any multivariate density can be decomposed through successive conditionings into basic building blocks involving only pairs of variables. The various ways in which this can be done are called regular vines; C-vines and D-vines are prime examples of such structures. A pair-copula construction (PCC) is a modelling strategy in which conditional and unconditional bivariate copula densities are assi...

The black-rot fungus, Myeosphaerella melonis (Pass.) Chiu and J. C. Walker, was first reported in France in 1891 on leaves of a Chinese variety of cucumber {CueUQyiis sativus L.) (¡^i) .^ It was recorded the next year from Delaware on vines of watermelon {Gitrullus vulgaris Sehr ad.), squash {Cucúrbita spp.), pumpkin {Cucúrbita pepo L.), muskmelon {Cucumis meló L.), and cucumber {3). Grossenbac...

but neither should be implicated in the views expressed here. I would also like to thank Chris Allsopp, Ron Smith and David Vines for useful comments at the conference.

In an investigation on nematode dist r ibut ion in a vineyard (1), difficulty arose in determining tile Meloidogyne spp. present. Chromosomal analysis indicated the presence of at least six populations, representing four species (2). T h e objective of this study was to determine any differences among the Meloidogyne populat ions in their distr ibution in the soil and between vines. T o m a t o...

In this article we present a model of insect infestation of grape vines and consider the optimal control of the pest through the use of egg pesticides. We show existence and uniqueness and present the results of some numerical simulations.

How do vines climb upward and harvest sunlight? A detailed study of one species (Galium aparine L.) shows that leaf hairs (trichomes) provide one solution that solves both tasks simultaneously.

The effect of gravity and sliding friction on the dynamics around targeted energy transfer an inclined vibro-impact nonlinear sink (VINES) is addressed. non-smooth first formulated in Signorini’s contact law treated using a Moreau-Jean scheme adapted with energy-conserving integration method. Exhaustive discussions are then carried out regarding vibration damping performance VINES, as well thei...

Alternaria leaf blight is a much greater threat to muskmelons than watermelons. The disease is caused by a fungus (Alternaria cucumerina) that can rapidly defoliate plants, causing reductions in bulk yield. Melons on defoliated vines ripen prematurely and result in lower quality fruit compared to melons produced on healthy vines. Yield losses greater than 50% will occur in situations where the ...

Rapid growth in networks and related services have resulted in demands for more e ective, accessible, intelligent and scalable network management systems. Not only managers but also users need access to network management information. Traditional network management architectures are utterly inadequate to meet these requirements. In this work we describe VINES a next generation network managemen...

A site was prepared with 2 distinctly different soil depths and a vineyard of 'Concord' grapes (Vitis labrusca L.) was established with in-row spacings of 1.52, 1.83, 2.13, 2.44, and 3.05 m. Wider in-row vine spacings resulted in increased vine yields on deeper soils to the point that yields per meter of cordon and per hectare were not reduced; but yield per meter of cordon and per hectare was ...
