The paper deals with an approach to the Inverse Problems based upon their relations to the Boundary Control Theory (the BC-method). A possibility to recover a velocity c = ("") ?1=2 via response operator of the Maxwell dynamical system is discussed. The main result is that the operator (plus values of c; @c @ at a boundary) determines velocity uniquely in the maximal near-boundary layer in whic...

We calculate the cross section of J/ψ plus jet inclusive production in γγ collisions at next-to-leading order within the factorization formalism of nonrelativistic quantum chromodynamics (NRQCD) focusing on direct photoproduction. Apart from direct J/ψ production, we also include the feed-down from directly-produced χcJ and ψ ′ mesons. We discuss the analytical calculation, in particular the tr...

Fig. 3. Plus signs: smooth flows (ii); squares: upstream moving shocks (iii); diamonds: steady shocks (iii); circles: oblique waves (i). Solid stars: flows with three possible states for different configurations and paddle lengths. Indicative error bars. • Three multiple steady states in regions (i/iii/iv): Fig. 4. Multiple states: F0 = 3.07 & Bc = 0.7. Left to right: upstream steady shock (iii...

An investigation was conducted to examine the impact of additive mixing with wheat straw (WS) for pellet making. This study manufactured seven types pellets different combinations evaluate quality characteristics and their relationships. A laboratory-type hammer mill a were used feedstock preparation production. Experimental investigations showed that lignin content increased from 7.0% 13.1%, w...

in the early of 1st millennium bc, in the region of lorestan, iran, the ellipi kingdom formed and played a significant role in regional developments, particularly in relation with two rival governments, assyria and elam. the political history reconstruction of the ellipi kingdom is more reliant on assyrian resources which cover just very short and particular part of its life. the first recorded...

The study examined the effect of board characteristics (BC) on financial performance (FP) deposit money banks (DMBs) in Nigeria between 2012-2021(10years). specific objectives is to examine relationship measures [Board Size (BS), Board Independence (BI), Gender Diversity (BGD) and Meeting (BM)] [performance proxy with Returns equity (ROE)]. focused 10 were drawn out 18 listed Nigerian Exchange ...
