The nonlinear system becomes an area with numerous investigations over the past decades. The conventional modal analysis could not be applied on nonlinear continuous system which makes it impossible to construct the reduced order models and obtain system response based on limited number of measurement points. Nonlinear normal modes provide a useful tool for extending modal analysis to nonlinea...
abstract this study aimed at investigating the translation of interjections from english into persian in dubbing. to carry out this study the expressive secondary interjections found in the film four weddings and a funeral and their equivalent in persian dubbed version were analyzed through the strategies proposed by cuenca. the descriptive analysis of the corpus showed that (strategy b) i.e...
in this paper, a structural damage identification method (sdim) is developed for plate-like structures. this method is derived using dynamic equation of undamaged/damaged plate, in which local change in flexural rigidity is characterized utilizing a damage distribution function. the sdim requires to modal data in the intact state and frequency response of damage state where most of vibration ba...
in this contribution, linearized dynamic model of cumulative mass fraction (cmf) of potassium nitrate-water seeded continues mixed suspension mixed product removal (cmsmpr) crystallizer is approximated by a simplified model in frequency domain. frequency domain model simplification is performed heuristically using the frequency response of the derived linearized models data. however, the cmf fr...
In this paper, a fully polarimetric time-frequency analysis method is introduced to decompose synthesized polarimetric and interferometric SAR images into range-frequency and azimuth-frequency domain. This 4-D representation permits to characterize the frequency response of the scene reflectivity, observed under different azimuth look-angles. A statistical analysis of polarimetric parameters pe...
burnout is a response to the chronic work stress which is prevalent mostly among the people who do people job, like teaching. the purpose of this study was to develop a valid and reliable instrument that can measure burnout in foreign language teachers. although some widely used instruments were developed before which measured burnout in teachers, a specific instrument which include specific sy...
This paper proposed an efficient and adaptive frequency sampling algorithm for response analysis using dynamic condensation-based reduced-order modeling. For the degree of freedom-based model reduction method, basis becomes a frequency-dependent matrix since relationship between master slave degrees freedom stems from partial equations second-order dynamical system. Such frequency-dependency ma...
New power systems based on VPP will be expanded in the future and analysis of the frequency behavior of these systems compared to current systems in the field of disruptions will be one of the most important issues of the system operators. In this paper, the equations of the frequency response model of conventional power system are expanded by considering the VPP's and their effective component...
