Neurons in area MT of primate visual cortex encode the velocity of moving objects. We present a model of how MT cells aggregate responses from VI to form such a velocity representation. Two different sets of units, with local receptive fields, receive inputs from motion energy filters. One set of units forms estimates of local motion, while the second set computes the utility of these estimates...

In this paper, a new frequency-domain approach to represent motions is proposed. The new scheme is based on a band-pass filtering with a set of logGabor spatio-temporal filters. It is well known that one of the main problems of these approaches is that a filter response varies with the spatial orientation of the underlying signal. To solve this spatial dependency, the proposed model allows to r...

in the current study, whey protein- pullulan- clay nanocomposite films are prepared by casting method. the effect of nanoclay at three concentrations (1%, 3% and 5%) on physical properties such as moisture content, solubility in water, water vapor permeability and transparency of whey protein- pullulan composite films investigated. the results show that the effect of nanoparticles on composite ...

We examine the phenomenon of electromagnetic transparency in semiconductor superlattices having various miniband dispersion laws in the presence of multi-frequency periodic and nonperiodic electric fields. Effects of induced transparency and spontaneous generation of static fields are discussed. We pay special attention to self-induced electromagnetic transparency and its correlation to dynamic...

We show that application of self-induced transparency (SIT) solitons as a driving field in V-type electromagnetically induced transparency (EIT) leads to ;;mixed induced transparency' (MIT) that nicely combines the best features of both SIT and EIT.

Innovations in electronic banking in Iran have led to the development in capacities such as payment instruments and transactions by cards, which are known as electronic payment equipment in the Iranian banking network. Financial supervision is required to be increasingly based on reporting and regulatory processes to efficiently and proactively monitor risk and compliance at banks and financial...
