in this study, the spatial distribution of overwintered adults of sunn pest, eurygaster integriceps puton, was investigated by using dispersion parameters and indices, mathematical distribution, and regression techniques in rainfed wheat fields by sample size of 1 m2 in 2009 and 2010. the dispersion parameters including: mean-variance test and clumping parameter () showed that the overwintered ...

We show that a left-invariant metric g on a nilpotent Lie group N is a soliton metric if and only if a matrix U and vector v associated the manifold (N, g) satisfy the matrix equation Uv = [1], where [1] is a vector with every entry a one. We associate a generalized Cartan matrix to the matrix U and use the theory of Kac-Moody algebras to analyze the solution spaces for such linear systems. We ...

This paper deals with Electronic Services Delivery, a form of Electronic Commerce in Services Sector. Firstly, it defines Electronic Commerce and Electronic Services Delivery and secondly, it presents the Current State of either both in Slovenia and in the World. The second part of the paper briefly presents the most interesting findings of an electronic Services Delivery and Electronic Commerc...

This paper introduces a variant for the symmetric matrix-based key distribution in sensor network introduced by Du et al. Our slight modification shows that the usage of specific structures for the public matrix instead of fully random matrix with elements in Zq can reduce the computation overhead for generating the public key information and the key itself. An intensive analysis followed by mo...

This review deals with the present state of knowledge of methods concerned with control of reproduction in the sheep and cattle industries of Australia. Most emphasis will be placed on recent advances in those areas of research likely to find relevance to the Australian animal production scene. There is a large and expanding volume of literature in this field. To keep references to a minimum re...

We find a class of flat supersymmetric brane-antibrane configurations. They follow from ordinary brane-antibrane systems by turning on a specific worldvolume background electric field, which corresponds to dissolved fundamental strings. We have clarified in detail how they arise and identified their constituent charges as well as the corresponding supergravity solutions. Adopting the matrix the...

Noncommutative geometric gauge theory is reconstructed based on the superconnection concept. The bosonic action of the Connes-Lott model including the symmetry breaking Higgs sector is obtained by using a new generalized derivative, which consists of the usual 1-form exterior derivative plus an extra element called the matrix derivative, for the curvatures. We first derive the matrix derivative...

This article examines the application of a popular measure of sparsity, Gini Index, on network graphs. A wide variety of network graphs happen to be sparse. But the index with which sparsity is commonly measured in network graphs is edge density, reflecting the proportion of the sum of the degrees of all nodes in the graph compared to the total possible degrees in the corresponding fully connec...

Therefore, the potential V is subquadratic and the operator − ε 2 ∆q+V (q) is essentially self–adjoint on the Schwartz space. Such systems naturally arise in quantum chemistry when studying the dynamics of large molecules in the frame of Born-Oppenheimer approximation. The parameter ε is small because it encounters for the ratio of the mass of the electron and of the averaged mass of the nuclei...
