continual bearing and production of the highest quality fruits in kiwi requires initial training and regular annual pruning. effects of three training systems including t-bar, as a common training system, modified ty (mty) and y-shape (y), and two pruning levels (60 and 80 buds per vine) was studied on yield and quality characteristics of kiwifruit ‘hayward’. experiment was carried out in a fac...

Let V and W be two real vector spaces and let &sim be a relation on both V and W. A linear function T : V → W is said to be a linear preserver (respectively strong linear preserver) of &sim if Tx &sim Ty whenever x &sim y (respectively Tx &sim Ty if and only if x &sim y). In this paper we characterize all linear functions T : M_{n,m} → M_{n,k} which preserve or strongly preserve multivariate an...

This paper proposes an improved predictor-corrector interior-point algorithm for the linear complementarity problem LCP based on the Mizuno-Todd-Ye algorithm. The modified corrector steps in our algorithm cannot only draw the iteration point back to a narrower neighborhood of the center path but also reduce the duality gap. It implies that the improved algorithm can converge faster than the MTY...

Combining these three definitions, Zamfirescu [12] proved the following important result. Theorem 1.1. Let (X ,d) be a complete metric space and T : X → X a mapping for which there exists the real numbers a,b, and c satisfying a∈ (0,1), b,c ∈ (0,1/2) such that for each pair x, y ∈ X , at least one of the following conditions holds: (z1) d(Tx,Ty)≤ ad(x, y), (z2) d(Tx,Ty)≤ b[d(x,Tx) +d(y,Ty)], (z...

   TiO2 based nanocomposites (NCs) were synthesized using the co-precipitation/hydrolysis (CPH) method. The composition of the first set (TZF) and the second set (TY) of NCs were: TiO2.[ZnFe2O4]x (with x = 0.1 to 0.5), and TiO2.[Y2O3]x (with x = 0.1 to 0.5), respectively. NCs with average crys...

for vectors x, y ∈ rn, it is said that x is left matrix majorizedby y if for some row stochastic matrix r; x = ry. the relationx ∼` y, is defined as follows: x ∼` y if and only if x is leftmatrix majorized by y and y is left matrix majorized by x. alinear operator t : rp → rn is said to be a linear preserver ofa given relation ≺ if x ≺ y on rp implies that t x ≺ ty onrn. the linear preservers o...

By a solution of (.) wemean a function y(t) ∈ C[ty,∞) which has the property r(t)y′(t) ∈ C[ty,∞) and r(t)(r(t)y′(t))′ ∈ C[ty,∞) and satisfies (.) on [ty,∞) for every t ≥ ty ≥ t. We restrict our attention to those solutions of (.) which exist on I and satisfy the condition sup{|x(t)| : t ≥ t} >  for any t ≥ ty. We assume that (.) possesses such a solution. A solution y(t) of (...
