Relaxed ferroelectric ceramics with good energy storage stability, high density and efficiency, charge/discharge rates have shown great potential for commercial applications. In this paper, 0.85[0.9BaTiO3 −0.1Bi(Ni0.5Zr0.5)O3]−0.15(Bi0.5Na0.5)0.7Sr0.3TiO3 ceramic was prepared via a solid – phase reaction method by doping (Bi0.5Na0.5)0.7Sr0.3TiO3 into 0.9BaTiO3 > −0.1Bi(Ni0.5Zr0.5)O3; it exhibit...

Abstract Ni-Ti-Cu alloy can not only prevent scale and biological adhesion, but also has applications in aerospace, automotive engineering, nanotechnology. In this study, Ni 50 Ti 40 Cu 10 45 15 large-size thin-walled parts are prepared on the surface of plates using laser additive manufacturing technology. The optimum operational parameters explored through a two-factor controlled variable met...

Abstract Based on the coprecipitation of FeSO 4 (NH ) 2 SO with CuCl and ZnSO , CuFe O ZnFe nanocrystals were successfully synthesized. The morphology crystal structures nanoparticles studied via SEM, TEM XRD, which showed that MFe samples formed aggregated sizes 16 ? 20 nm a narrow dispersion in size. had typical spinel structures. Magnetic analyses demonstrated sample saturation magnetization...

Recently, fractal and subband coding were combined to achieve good picture quality at very low bit rates, and the technique was named predictive pyramid coding (PPC) [5]. In this paper, we improve PPC performance by utilizing the inter-subband correlation between different groups of subbands. As a result, we can reduce the bit rate by 0.0110.043 bpp without degrading the coded picture quality,...

Two bookmakers compete in Bertrand fashion while setting odds on the outcomes of a sporting contest where an influential punter (or betting syndicate) may bribe some player(s) to fix the contest. Zero profit and bribe prevention may not always hold together. When the influential punter is quite powerful, the bookies may coordinate on prices and earn positive profits for fear of letting the ‘lem...
