An efficient approach using LPFT for the karaoke formation of musical song

Abstract: In today's world the music professionals are facing challenges when they want to practice on any song. The challenge is that the instrumentalists are not available at all times to accompany them. Thus there is an increase demand of the karaoke systems that can generate the instrumental music without having the vocals. This creates a significant need to develop such kind of systems. In this paper we are proposing an efficient approach that helps in creating the karaoke of any song and removes the vocal part from any song. Lots of researchers are focusing on using different aspects, we propose the LPF Technique that is exploited to separate the vocal and the instrumental portion from the song clip. As there is room for additional improvements for the system, the proposed technique is useful and easy to use with the proven validations. The strategy uses the matlab programming environment and the filtering techniques. Using the Matlab GUI one working prototype has been proposed that helps user to create the karaoke which is the vocal separated instrumental only.

Dynamical behaviour of parametrically driven Duffing and externally driven Helmholtz–Duffing oscillators under nonlinear dissipation

Abstract: In this paper, we mainly focus our attention on the global dynamical behaviour of some ubiquitous nonlinear oscillators under the presence of nonlinear dissipation. We particularly consider the parametrically driven Duffing oscillator and externally driven Helmholtz–Duffing oscillators with nonlinear dissipation term proportional to the power of velocity $$(v\left| v \right| ^{p-1})$$ . We obtain the threshold condition for the occurrence of chaos analytically as well as numerically for all the cases $$p=$$ 1, 2, 3 and 4. We also identify the regions of 2D parameter space (consisting of external forcing amplitude and damping coefficient) corresponding to various asymptotic dynamics and analyse the effect of nonlinear damping on the overall dynamical behaviour of these nonlinear oscillators.

Differential cross section calculations of positron and electron impact ionization of Ar (3p)

Abstract: We report the distorted wave Born approximation results of triple differential cross section of Ar (3p) by positron and electron impact. We compare the results of our calculations with the recent available experimental and theoretical results. We also provide a comparison of our positron impact ionization results with the electron impact ionization results to understand the effect of projectile charge on the projectile-target interaction.
