We study the regularity of the extremal solution of the semilinear biharmonic equation ∆u = λ (1−u)2 , which models a simple Micro-Electromechanical System (MEMS) device on a ball B ⊂ R , under Dirichlet boundary conditions u = ∂νu = 0 on ∂B. We complete here the results of F.H. Lin and Y.S. Yang [14] regarding the identification of a “pull-in voltage” λ > 0 such that a stable classical solutio...

This paper deals with some uniqueness problems of meromorphic functions concerning their differential polynomials sharing the fixed-points or a small function with finite weight. These results in this paper greatly improve the recent results given by X.-Y. Zhang& J.-F. Chen and W.C. Lin[X.-Y. Zhang, J.-F. Chen, W.C. Lin , Entire or meromorphic functions sharing one value, Comput. Math. Appl. 56...

HyperMask is a system which projects an animated face onto a physical mask, worn by an actor. As the mask moves within a prescribed area, its position and orientation are detected by a camera, and the projected image changes with respect to the viewpoint of the audience. The lips of the projected face are automatically synthesized in real time with the voice of the actor, who also controls the ...

An innovative material constituted of a natural biopolymers blend (Funori) from Gloiopeltis algae and Ca(OH)2 nanocrystals was developed to consolidate linen fibers for cultural heritage conservation preventing future degradation due the alkaline reservoir by Ca(OH)2. The procedure extract Funori reliable reproducible consolidation performances aged Funori/Ca(OH)2 smart system were showed highl...

Traditional theories on ancient Egyptian mummification postulate that in the prehistoric period (i.e. the Neolithic and Chalcolithic periods, 5th and 4th millennia B.C.) bodies were naturally desiccated through the action of the hot, dry desert sand. Although molding of the body with resin-impregnated linen is believed to be an early Pharaonic forerunner to more complex processes, scientific ev...

Asbestos is named from the Greek asbeston, meaning inextinguishable or unquenchable, and describes not a single mineral, but a number of silicates distinguished by their fibrous structure, flexibility, strength and high resistance to heat and chemicals. These properties ensured the minerals’ use from the earliest times. Archaeologists have identified asbestos as a strengthener in earthenware fr...

Symmetric 2,5-bisazopyrroles 2(a-d) were synthesized by a one-step reaction of substituted phenyl diazonium salts [R'(Ph)N2(+)Cl-] [a, R' = 4-N(CH3)2; b, R' = 2-OH; c, R' = 2-CO2H; d, R' = 4-NO2] with pyrrole under basic conditions. Asymmetric 2,5-bisazopyrroles 3(a-d) were synthesized by reacting substituted phenyl diazonium salts [R''(Ph)N2(+)Cl-] (a, R'' = 4-OCH(3); b, R'' = H; c, R'' = 4-Br...
