Excitation spectrum of an antiferromagnetic film with a non-uniform ground state
Journal of Physics: Condensed Matter, 1995Using a microscopic approach, we study the elementary excitations for a uniaxial antiferromagnetic film with an external magnetic field H applied along the easy axis. For H greater than a critical value, HS, the system has a non-uniform ground state which is obtained, very rapidly and with high accuracy, in terms of a two-dimensional area preserving ...

Response Characteristics of Large Span Structures Subjected to Non-Uniform Vertical Excitations
Advanced Materials Research, 2012The objective of this paper is to study the response characteristics of large span structures subjected to multiple vertical excitations by means of time history analyses. The spatial variation of ground motions are represented as the combined effect of wave-passage and incoherency.

Dynamic response analysis of RC bridge subjected to non-uniform seismic excitations
2011 International Conference on Remote Sensing, Environment and Transportation Engineering, 2011This study aims to reveal the dynamic response of a reinforced concrete rigid frame bridge subjected to non-uniform seismic excitations. Based on the displacement method and improved large mass method, an acquire technique for quasi-static/dynamic components of structural seismic responses has been presented and validated through numerical simulations.

A Comprehensive Method to Improve Gain from Symmetric Non-Uniform Linear Array
2024 2nd International Conference on Sustainable Computing and Smart Systems (ICSCSS)A non-uniform linear array design issue with real symmetric excitation for achieving a maximal pencil beam in the desired direction is presented. The method of convex optimization is employed to determine the optimal antenna element spacing and the ...

Shaking table test of utility tunnel under non-uniform earthquake wave excitation
Soil Dynamics and Earthquake Engineering, 2010Abstract A series of shaking table tests were conducted on scaled utility tunnel models with and without construction joints under non-uniform input earthquake wave excitation. Details of experimental setup are first presented with particular focuses on: design and fabrication of double-axis laminar shear box with a rectangular hole opened on its ...

Transverse collective instability excited by a non-uniform v-shift in intense beams
Nuclear Instruments and Methods, 1973Abstract A model which describes the effect of a non-uniform space charge v-shift on the resistive wall instability associated with transverse collective oscillations of a beam of particles is proposed. It successfully predicts the overall characteristics of the instability as observed at the CERN ISR: (1) the observation of a current limitation in ...
