In order to determine the best index for evaluating maize genotypes, 28 maize hybrids were evaluated in two planting dates, 6 July to coincide heat stress with pollination time and 27 July as normal planting to avoid high temperature during pollination and grain filling period, using a randomized complete block design with three replications, in Shushtar city, in 2008. Results showed that in st...

where ∂i = ∂/∂x i and D = ∪ 0≤t≤T {t}×Dt, Dt ⊂ R. Here V k = δvi = vk and we use the summation convention over repeated upper and lower indices. The velocity vector field of the fluid is V , p is the pressure and Dt is the domain the fluid occupies at time t. We also require boundary conditions on the free boundary ∂D; p = 0, on ∂D, (1.3) (∂t + V ∂k)|∂D ∈ T (∂D), (1.4) Condition (1.3) says that...

This equation is regular and already in normal form. We obtain the eigenvalues from the characteristic equation: α + ω = 0 α = −ω α = ±iω This gives {e} as eigenfunctions. However, since the original equation has real coefficients, we would like a basis of real-valued eigenfunctions. Since Re(e) = cosωx and Im(e) = sinωx, we take {cosωx, sinωx} as a basis. Thus the eigenfunctions of (?1) are al...

Let (* ) u,, du + q(x, t) u = 0 in D x [0, T], where D c R3 is a bounded domain with a smooth boundary dD, T> d, d: =diam D, q(x, I) E C( [O, 2’1, L”(D)). Suppose that for every (**) ~I,+~=f(x, l)EC’(dDx [0, T]), the value u*,;,:= h(s, t) is known, where N is the outer normal to dD, u solves (* ) and ( ** ) and satisfies the initial conditions u = U, = 0 at I = 0. Then q(x, I) is uniquely deter...

The trend towards larger wind turbines and remote locations of farms fuels the demand for automated condition monitoring strategies that can reduce operating cost avoid unplanned downtime. Normal behaviour modelling has been introduced to detect anomalous deviations from normal operation based on turbine’s SCADA data. A growing number machine learning models turbine subsystems are being develop...
