Transient Angle Stability of Virtual Synchronous Generators Using Lyapunov’s Direct Method
IEEE Transactions on Smart Grid, 2019With an increasing number of distributed energy resources integrated into the power system, inverters need to take on the corresponding responsibility for the security and stability of the system.

In this paper, the direct-projection method given by Benzi and Meyer (1995) is derived by slightly different way - Basic Solutions of corresponding homogeneous system. The idea of the method differs from the idea of the Gaussian Elimination (or LU decomposition). The method works for every nonsingular coefficient matrix in the absence of rounding error.

Direct methods in surface crystallography
Vacuum, 1988Inspired by the heavy atom technique used in X-ray diffraction, the inversion of the Tensor LEED method is used to obtain structure information directly from experimental IV spectra i.e. without the usual trial and error procedure. From a LEED calculation for a certain reference structure (‘heavy atom’), intensities for neighboured structures can be ...

THE DIRECT METHOD, REDUCIBILITY
Mathematics of the USSR-Izvestiya, 1991Consider the linear system (*) \(dx/dt=\lambda P(t)x\) where \(P\) is a quasi-periodic matrix with the frequency basis \(\alpha\) and 1 (\(\alpha\) is an irrational number), \(\lambda\) is a complex parameter. Let \(\alpha=p_ k/q_ k+(-1)^ k/)q_ kq_{k+1})+(- 1)^{k+1}/(q_{k+1}q_{k+2})+\cdots\).

Acta Crystallographica Section A Foundations and Advances, 2019
The standard method of joint probability distribution functions, so crucial for the development of direct methods, has been revisited and updated. It consists of three steps: identification of the reflections which may contribute to the estimation of a given structure invariant or seminvariant, calculation of the corresponding joint probability ...

Author's summary.— The “direct” method of teaching a foreign language is not direct so far as the initial presentation of the vocabulary is concerned.

The unshielded twisted pair can be used as a transmission media for local distribution networks. To maintain a high transmission throughput, an analog or a digital adaptive channel equalizer is usually required in the receiver to minimize the effect of inter-symbol interference.

Alternating Direction Implicit Methods
1962Publisher Summary Alternating direction implicit methods, or ADI methods as they are called for short, constitute powerful techniques for solving elliptic and parabolic partial difference equations. However, in contrast with systematic overrelaxation methods, their effectiveness is hard to explain rigorously with any generality.
