This article considers the main parameters of experimental rotary working body (RWB) used for tillage and opening buried vines in protection zone between rows, soil loosening weeding blades crop zone, as well number paddles vines. The performance indicators largely depend on its kinematic mode operation, knives, dumps picks. destruction weeds root movement required volume towards row spacing is...

This paper proposes a novel approach for living and missing vine identification characterization in goblet-trained plots using aerial images. Given the periodic structure of goblet vineyards, RGB color coded parcel image is analyzed proper processing techniques order to determine locations vines. Vine achieved by implementing marker-controlled watershed transform where centers vines serve as ob...

As the ancestor of cultivated grape, Vitis vinifera subsp. sylvestris represents a unique, invaluable genetic resource for the improvement of cultivated grapevines. Recently, five populations of wild grapevines were identified in Portugal. Sixty vines were characterized with 11 nuclear SSR markers and further compared with 70 genotypes of Portuguese Vitis vinifera subsp. sativa. The obtained da...

The aim of this paper is to propose a novel approach to integrate financial information, incorporating the dependence structure among the variables. The approach is based on two types of graphical models: vines and non parametric Bayesian belief nets (NPBBNs). Vines are undirected graphs, representing pair copula constructions, which are used to model the dependence structure of a set of variab...

A method of representing transformations of a finite set pictorially is described. These pictures of a function are used to count certain idempotent transformations, and interesting formulae for the Fibonacci numbers are obtained. No part of any string extends beyond the region ° : : ; z ::; 1, and if two strings intersect then they join together, from the point of intersection, to meet the sam...

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 ...
