in this note the notion of interval-valued fuzzy b-algebras (briefly,i-v fuzzy b-algebras), the level and strong level b-subalgebra is introduced.then we state and prove some theorems which determine the relationshipbetween these notions and b-subalgebras. the images and inverse images ofi-v fuzzy b-subalgebras are defined, and how the homomorphic images andinverse images of i-v fuzzy b-subalge...

We study a model system with nematic and magnetic order, within channel geometry modeled by an interval, $[-D, D]$. The is characterized tensor-valued order parameter ${{Q}}$ vector-valued magnetization ${{M}}$, the observable states are as stable critical points of appropriately defined free energy which includes nemato-magnetic coupling term, $c$. (i) derive $L^\infty$ bounds for ${{M}}$; (ii...

‎selecting the most suitable robot among their wide range of specifications and capabilities is an important issue to perform the hazardous and repetitive jobs‎. ‎companies should take into consideration powerful group decision-making (gdm) methods to evaluate the candidates or potential robots versus the selected attributes (criteria)‎. ‎in this study‎, ‎a new gdm method is proposed by utilizi...
