Aerial safety separation is an important indicator to evaluate the flight performance of medium and low speed combination aircraft. In this paper, concept impact box safe corridor will be introduced for air problem composite aircraft, a numerical method quickly obtaining area aircraft proposed: influence box-corridor method, suitable generation studied by method. The article introduces simplifi...

the process of poetry in kuwait has always been progressive during the past centuries as well as the present century. this progression has raised remarkable questions such as is the good economical situation because of the foundation of petrol in this country and so on. the last question is about the time of formation of rticulate poetry in kuwait. the poets of kuwait do not care about the publ...

‎let us consider the set of non-abelian finite simple groups which‎ ‎admit non-trivial irreducible projective representations of degree $le 7$ over‎ ‎an algebraically closed field $f$ of characteristic $pgeq 0$‎. ‎we survey some recent results which‎ ‎lead to the complete list of the groups in this set which are‎ ‎$(2‎, ‎3‎, ‎7)$-generated and of those which are $(2,3)$-generated‎.

Light isotopes separation, such as (3)He/(4)He, H2/D2, H2/T2, etc., is crucial for various advanced technologies including isotope labeling, nuclear weapons, cryogenics and power generation. However, their nearly identical chemical properties made the separation challenging. The low productivity of the present isotopes separation approaches hinders the relevant applications. An efficient membra...
