Let Ω ⊂ R, n ≥ 2, be a bounded domain with smooth boundary. Consider utt −4xu+ q(x, t)u = 0 in Ω× [0, T ] u(x, 0) = 0, ut(x, 0) = 0 if x ∈ Ω u(x, t) = f(x, t) on ∂Ω× [0, T ] We show that if u and f are known on ∂Ω× [0, T ], for all f ∈ C∞ 0 (∂Ω× [0, T ]), then q(x, t) may be reconstructed on C = { (x, t) : x∈Ω, 0 < t < T, x− tω & x+ (T − t)ω 6∈ Ω ∀ ω ∈ R, |ω| = 1 } provided q is known at all po...

1571 A multi-heat addition turbine engine (MHATE) incorporates a plurality of heat addition devices to transfer energy to air and a plurality of turbines to extract energy from the air while converting it to work. The MHATE provides dry power and lower fuel consumption or lower combustor exit temperatures. 2,501.181 4/1950 Constant ............................ 60/226.1 2 Claims, 4 Drawing Sheet...

This paper proposes to augment C++11’s TransformationTraits with a number of template aliases whose use dramatically simplifies the traits’ most common applications.

Serial measurements of urinary adrenaline, noradrenaline, and 11-hydroxycorticosteroid excretion were performed on 32 healthy men under two conditions of work stress; piecework and work on assembly line. A statistically significant increase in adrenaline, noradrenaline, and 11-hydroxycorticosteroids was observed for piecework and assembly line workers compared with salaried and 'ordinary' worke...

The catalytic effect of Zirconia Sulfuric Acid (ZrSA) nanoparticle which is synthesized from thereaction of ZrO with chlorosulfonic acid has been investigated in the synthesis oftetrahydrobenzo[a]xanthene-11-ones by one-pot three-component reaction of β-naphthol,aromatic aldehydes, and dimedone. Different reaction conditions were studied in the presence ofZrSA nanoparticle as catalyst. The resu...
