This paper discusses the importance and difficulties associated with testing analog circuits in general and those residing within mixed-signal circuits in particular. It proposes a tested method that is not specification oriented. The method is based on the excitation of the circuit-under-test with a pseudo random binary sequence and the subsequent analysis of the captured response. The fault d...

large capacity cylindrical tanks are used to store a variety of liquids. their satisfactoryperformance during earthquake is crucial for modern facilities. in present paper, the behavior of cylindricalconcrete tanks under harmonic excitation is studied using the finite element method. liquid sloshing, liquidviscosity and wall flexibility are considered and additionally excitation frequency, liqu...

europium (eu) doped zno microsphere based nano-sheets were synthesized through hydrothermal method. effects of different concentrations of europium on structural and optical properties of zno nano-sheets were investigated in detail. prepared un-doped and eu-doped zno samples were characterized using x-ray diffraction (xrd), energy dispersive x-ray spectroscopy (edx), scanning electron microscop...

An improved Penzien model is proposed in this paper as a simplified of soil–pile–structure interaction. The dynamic nonlinearity soil under earthquake excitation simulated by ANSYS free-field and added to the original model. uses finite element software 2021 simulate soil. then used calculation numerical substructure. A substructure pseudo-dynamic test based on carried out. realization verifies...

Original scientific paper The objectives of this paper are to perform a comparative analysis of the large-scale system of a high-pier railway bridge subjected to stationary and nonstationary spatially varying earthquake excitations using the pseudo-excitation method (PEM), and to estimate whether or not the non-stationary stochastic analysis of the high-pier railway bridges under tri-directiona...

In this paper, we introduce the concept of interval pseudo-homegeneous uninorms. We extend the concept of pseudo-homogeneity of specific functions for interval pseudo-homogeneous functions. It is studied two cases of interval pseudo-homogeneous uninorms, that is, interval pseudo-homogeneous tnorms and interval pseudo-homogeneous t-conorms. It is proved a form of interval pseudo-homogeneous t-no...
