Approximate likelihood inference in generalized linear latent variable models based on integral dimension reduction

, 2015
Latent variable models represent a useful tool for the analysis of complex data when the constructs of interest are not observable. A problem related to these models is that the integrals involved in the likelihood function cannot be solved analytically.

State estimation of variable frequency power grid of multi-electric aircraft based on adaptive enhanced complex-coefficient filter

Xibei Gongye Daxue Xuebao
The power grid of a multi-electric aircraft is a typical isolated island microgrid with a wide frequency range from 360 to 800 Hz. The dynamic performance of the traditional constant-frequency power grid synchronization method is insufficient in the ...

A Monte Carlo evolution of the Functional Resonance Analysis Method (FRAM) to assess performance variability in complex systems

Safety Science, 2017
Abstract Modern trends of socio-technical systems analysis suggest the development of an integrated view on technological, human and organizational system components. The Air Traffic Management (ATM) system can be taken as an example of one of the most critical socio-technical system, deserving particular attention in managing operational risks and ...

On generation of Julia sets, Mandelbrot sets and biomorphs via a modification of the viscosity approximation method

Results in Control and Optimization
Iterative methodology has been demonstrated to be an achievement in the age of fractals. A novel method based on the viscosity approximation approach, one of the most popular iterative techniques for identifying non-linear operator fixed points, for ...

100% of the zeros of the Riemann zeta-function are on the critical line

, 2019
We consider a specific family of analytic functions $g_{\alpha,T}(s)$, satisfying certain functional equations and approximating to linear combinations of the Riemann zeta-function and its derivatives of the form $c_0\zeta(s)+c_1\frac{\zeta'(s)}{\log T}

COMPLEX METHOD OF SEEKING THE MAXIMUM OF NON-NEGATIVE FUNCTION OF TWO VARIABLES

Jixie qiangdu, 2018
The optimization problems of binary functions widely exist in many practical engineering problems,their global optimization methods have always been one of the hot research issues. A high effective method of global optimization to nonnegative binary functions was put forward basing on the maximum modulus theorem of the analytic function of complex ...
