The transferability of adversarial examples is the key property in practical black-box scenarios. Currently, numerous methods improve across different models trained on same modality data. investigation generating video with imagebased substitute to attack target models, i.e., cross-modal examples, rarely explored. A few works directly apply image for each frame and no factors especial data are...

We have developed a theory that unifies the analysis of the modal properties of surface-emitting chirped circular grating lasers. This theory is based on solving the resonance conditions which involve two types of reflectivities of chirped circular gratings. This approach is shown to be in agreement with previous derivations which use the characteristic equations. Utilizing this unified analysi...

In a natural environment, objects that we look for often make characteristic sounds. A hiding cat may meow, or the keys in the cluttered drawer may jingle when moved. Using a visual search paradigm, we demonstrated that characteristic sounds facilitated visual localization of objects, even when the sounds carried no location information. For example, finding a cat was faster when participants h...

This paper deals with designing material parameters for physical models. It is shown that the characteristic relation between modal frequencies and damping factors of a sound object is the acoustic invariant of the material from which the body is made. Thus, such characteristic relation can be used for designing damping models for a conservative physical model to represent a particular material.

A modal analysis of transverse electromagnetic (TEM) mode in a circular–rectangular coaxial waveguide is presented in this paper. The analysis is based on the modal-expansion technique. Analytic expressions for the characteristic impedance and attenuation coefficient are derived from the solution of the TEM mode. The calculated results are compared with those of the finite-element method, as we...

in the present paper, we are to put forth a paradigm for the systematic study of modality in persian.with this end in view, we consider modality as a linguistic phenomenon that can be expressed at the level of sentence, at the level of constituents smaller than sentence and/or at the level of discourse. in such a system where sentential modality, sub-sentential modality and discourse modality a...

suhrawardi’s logic of the hikmat al-ishraq is basically modal. so to understand his modal logic one first has to know the non-modal part upon which his modal logic is built. in my previous paper ‘suhrawardi on syllogisms’(3) i discussed the former in detail. the present paper is an exposition of his treatment of modal syllogisms. on the basis of some reasonable existential presuppositions and a...

the problem of crack identification in continuous beam like structures is considered. the cracks’ locations and their depths are identified by employing experimental modal test results performed on the structure. the cracks are modeled using generic elements to include the coupling effects between shear forces and bending moments at the crack section. in the identification procedure eigen- sens...
