ZnO ceramic resistor doped with 3% MgO (mole fraction) has positive temperature coefficient. The linear property and energy density of the ZnO ceramic resistor were controlled by changing cooling rate. ZnO ceramic resistors with energy density greater than 450J/cm3 and good linearity were obtained.
According to the lack of the original reliability parameter and the necessity of exploiting original reliability parameter small stylebook,a linear combination forecasting model of original reliability parameter of power systems is proposed.
As in the case of affine Weyl groups, they can be obtained by adding a further node to the diagram for the linear part.
We discuss the linear independence of systems ofmvectors in n-dimensional complex vector spaces where the m vectors are time-frequency shifts of one generating vector.
An approximation of the linear fractional stable motion by a Fourier sum is presented.
However, the restrictions on g(u) do not allow the resulting restoring force function to increase faster than the linear function u-1 for u>amp;gt;1.
By using the Smith normal form of polynomial matrix and algebraic methods, this paper discusses the solvability for the linear matrix equation ΣAiXBi=C over a field, and obtains the explicit formulas of general solution or unique solution.
Reductive group actions on affine quadrics with 1-dimensional quotient: Linearization when a linear model exists
Such an action is called linearizable if it is equivalent to the restriction of a linear orthogonal action in the ambient affine space of the quadric.
A linear model for a given action is a linear orthogonal action with the same orbit types and equivalent slice representations.
We prove that if a reductive group action on an affine quadric with a 1-dimensional quotient has a linear model, then the action is linearizable.
More precisely, we show that under some conditions on X, every such automorphism is of the form Φ = ?g, where ? is an algebraic action of a linear algebraic group G of dimension 1 on X, and where g belongs to G.
