  2010 AUG 5 - (VerticalNews.com) -- According to a study from Perth, Australia, "The generalized nonlinear K (n, n) and B B M equations with variable coefficients are investigated under suitable conditions."

  "Applying the auxiliary differential equation techniques, we derive various explicit travelling wave solutions with different physical structures for the equations," wrote X.M. Lv and colleagues, Curtin University of Technology ...read more

  2010 AUG 5 - (VerticalNews.com) -- "In this paper, we propose a method for the numerical solution of singularly perturbed two-point boundary-value problems (BVPs). The artificial viscosity has been introduced to capture the exponential features of the exact solution on a uniform mesh and then the B-spline collocation method leads to a tridiagonal linear system," scientists writing in the journal Mathematical and Computer Modelling report ...read more

  2010 AUG 5 - (VerticalNews.com) -- "Estimating the fundamental frequency and harmonic parameters is basic for signal modelling in a power supply system. This paper present a gradient based algorithm and a least squares based algorithm to estimate the fundamental frequency, the amplitudes and the phased of harmonic waves according to the voltage/current samples of a power system," scientists in Jinan, People's Republic of China report ...read more
