We study the second order nonlinear differential equation: (E) y′′ +h(t) f (y) = 0, 0 < t < 1, h(t) ∈ L1(0,1), f (y) ∈C(R,R+) subject to multi-point boundary conditions: (i) y(0) = m ∑ i=1 αiy(ξi), y(1) = m ∑ i=1 βiy(ξi), (ii) y′(0) = m ∑ i=1 αiy′(ξi), y(1) = m ∑ i=1 βiy(ξi), (iii) y(0) = m ∑ i=1 αiy(ξi), y′(1) = m ∑ i=1 βiy′(ξi), where 0 < ξ1 < · · · < ξm < 1,αi 0,βi 0, i = 1,2, · · · ,m . We ...

The so-called multiple hypothesis technique is applied to solve a recognition problem that can be divided into at least two sub-problems. The principle of the technique is to solve the sub-problems by recognisers, a pre-recogniser and a post-recogniser, and to allow the pre-recogniser to leave several possible solutions to the post-recogniser. The pre-recogniser uses several hypotheses based on...

The R-type corrections to ten and eleven dimensional supergravity required by string and M-theory imply corrections to supersymmetric supergravity compactifications on manifolds of special holonomy, which deform the metric away from special holonomy. Nevertheless, in many such cases, including Calabi-Yau compactifications of string theory and G2-compactifications of M-theory, it has been shown ...

We study the existence of solutions anH-system for a revolution surface without boundary for H depending on the radius f . Under suitable conditions we prove that the existence of a solution is equivalent to the solvability of a scalar equation N(a) = L/√2, where N : ⊂ R+ → R is a function depending on H . Moreover, using the method of upper and lower solutions we prove existence results for so...

rose (rosa hybrida l.) is one of the mostly cultivated cut flowers in iran and around the world. the study was carried out to increase the vase life and quality of cut rose ‘grand prix` and ‘avallanche` by using various floral preservative solutions. floral preservative solutions were agno3, 8-hqs, nano silver and distilled water. treatments were compared with tap water as control. the experime...

The objective of this study was to quantify the genetic associations between a range of carcass-related traits including wholesale cut weights predicted from video image analysis (VIA) technology, and a range of pre-slaughter performance traits in commercial Irish cattle. Predicted carcass cut weights comprised of cut weights based on retail value: lower value cuts (LVC), medium value cuts (MVC...

In practice, cutting large number of pieces with different shapes often requires a well plan of assigning number of shapes on the cut template. The working arrangement of the cut-template is treated as Cut order plan (COP). The aim is to optimize cutting templates of fabric cutting function in apparel manufacturing firms when the cut order requirement is known. This solving of cut order plan pr...

Recovering intrinsic low-dimensional subspaces from data distributed on them is a key preprocessing step to many applications. In recent years, a lot of work has modeled subspace recovery as low-rank minimization problems. We find that some representative models, such as robust principal component analysis (R-PCA), robust low-rank representation (R-LRR), and robust latent low-rank representatio...
