Study of the effect of different music stimuli on autonomic nervous system of a single subject

Abstract: Study of the effect of music on autonomic nervous system of human being through the analysis of Heart rate variability (HRV) signals is a very recent area of research. The present paper considers the effect of seven different types of music stimuli on a single subject. The data of the HRV signals are subjected to a recently developed technique known as `frequency-delay plot'. The quantification is done by `ellipsoid fit' and allied five different types of quantification measures. Such results of quantification are then analyzed by the method of 'randomized block ANOVA. It is proved that all the different types of music stimuli have different effects on ANS of the subject, and that the effects are significantly different. Moreover the five different measures also do differ significantly on the music data. Finally to test which music signal affects ANS most, we consider, as population, the totality of all data corresponding to different types of songs and different types of measures taken. By considering the data of individual song under all measures as data of a sample, we calculate the interval of confidence of the population mean and the population variance with the help of each sample mean and sample variance at 0.95 level of confidence. It is proved that the length of confidence interval for population mean as well as for population variance is minimum only in the case of song1. In other words, it means that song1 is the most effective one on ANS of the subject.

Does Music Affect HRV Impulse? A Time Domain Study

Abstract: The two-dimensional (2D) Poincare plot of HRV signal reflects the effect of different external stimuli on ANS. The classification is generally done by fitting an ‘ellipse’ on the dense region of the constructed Poincare plot of HRV signal. However, 2D Poincare plot sometimes fails to describe the proper behaviour of the system. One such example is 2D Poincare plot of HRV signal in pre-music and on-music condition. In fact, 2D Poincare plots in pre and on-music condition look almost similar for few subjects. So a proper classification tool is sought for. In this article, an improved technique called ‘3D Poincare plot with proper delay’ has been applied to properly distinguish the pre-music and on-music state of some normal healthy subjects.

Free Vibration Analysis of Laminated Composite Plates and Shells Subjected to Concentrated Mass at the Centre

Abstract: In this present paper, we deal with free vibration analysis of laminated composite plates and shell panels with concentrated mass at the centre of the shell. Two types of mass lumping schemes (RWOERI and RWERI) have been proposed in the present study. In one of the mass lumping schemes, effect of rotary inertia has been included. First-order shear deformation theory has been incorporated in the formulation. The entire finite element programme has been written using FORTRAN language. A nine-noded isoparametric shallow shell element has been used. Cylindrical composite shell panels having different boundary conditions with various concentrated masses at the centre have been analysed.

Optimal control problem of a replicator system on differentiable manifold with boundary

Abstract: The paper discusses constrained optimal control problem of the functional on a replicator system with restrictions in the domain of definition on the objective functional, in the sense that the domain is an open manifold with boundary where the boundary is a differentiable variety.
