We present the preferential filtering method for gravity anomaly separation based on Green equivalent-layer concept and Wiener filter. Compared to the conventional upward continuation and the preferential continuation, the preferential filtering method has the advantage of no requirement of continuation height. The method was tested both on the synthetic gravity data of a model of multiple rect...

The multilinear PageRank model [Gleich et al., SIAM J Matrix Anal Appl, 2015;36(4):1507–41] is a tensor-based generalization of the model. Its computation requires solving system polynomial equations that contains parameter ? ? [ 0 , 1 ) . For ? this remains challenging problem, especially since solution may be nonunique. Extrapolation strategies start from smaller values and “follow” by slowly...

In this paper we study synchronization phenomena of spin-torque oscillators coupled on a ring. Spin-torque are nanoelectronic devices that promise efficient microwave generation provided they synchronized in large arrays. Due to their nonlinear and non-isochronous nature, properties difficult analyse explicitly. To address challenge, employ recently developed continuation method transform the n...

A non-interior continuation method is proposed for nonlinear complementarity problems. The method improves the non-interior continuation methods recently studied by Burke and Xu 1] and Xu 29]. Our deenition of neighborhood for the central path is simpler and more natural. In addition, our continuation method is based on a broader class of smooth functions introduced by Chen and Mangasarian 7]. ...

background : there are various variables such as the duration and the client consistency' in using a special contraceptive method as well as some individual determinants. which play important roles in optimal using of different contraceptive methods. iud cu- 380a is a safe and an effective method used by 12.5% urban women in east azarbaijan. correlation between continuation rate of using iud cu...
