  • Azimuthal Anisotropy in High Energy Nuclear Collision – An Approach based on Complex Network Analysis
    Recently, a complex network based method of Visibility Graph has been applied to confirm the scale-freeness and presence of fractal properties in the process of multiplicity fluctuation. Analysis of data obtained from experiments on hadron-nucleus and nucleus-nucleus interactions results in values of Power-of-Scale-freeness-of-Visibility-Graph-(PSVG) parameter extracted from the visibility graphs. Here, the relativistic nucleus-nucleus interaction data […] keyboard_arrow_right

In this […] keyboard_arrow_right
  • Book: Chaos based on quantitative risk assessment of cardiac dysfunction
    Congestive Heart Failure(CHF) is a growing menace spreading its jaws worldwide. As for all diseases, early detection of the disease is the key to thwart the rampage caused by the disease. With the existent diagnostic devices and methodologies, cost of diagnosis is high and some are painful due to their invasive nature. This book discusses […] keyboard_arrow_right
  • Chaos Based Quantitative Risk Assessment of Cardiac Dysfunction
    Congestive heart failure (CHF) is a condition in which the heart is unable to pump sufficiently to maintain blood flow to meet the needs of human body. In CHF, blood pumping power of heart muscles becomes weaker compared to that of normal heart muscles. Coronary artery diseases, record of past heart attack (myocardial infarction), hypertension, […] keyboard_arrow_right
  • Clan-Model of Particle Production Process-Revisited in Chaos-based Complex Network Scenario
    The multiplicity-distribution of High-Energy-Interaction, had earlier been analysed w.r.t. clan-model and Negative-Binomial-Distribution(NBD), which described the underlying particle production process by means of cascading mechanism. Clan was defined to contain the particles stemming from the same ancestorsand Average-multiplicity within clan was deduced from the best fitted NBD for the multiplicity-distribution of full-phase-space. Since latest data couldn’t […] keyboard_arrow_right
  • Detecting tāla Computationally in Polyphonic Context – A Novel Approach
    In North-Indian-Music, tabla is mostly used as percussive accompaniment for vocal-song in polyphonic-composition. Human auditory system uses perceptual grouping of musical-elements and easily filters the tabla component, thereby decoding prominent rhythmic features like, tempo from a polyphonic-composition. For Western music, lots of works had been reported for automated drum analysis of polyphonic-composition. However, in the […] keyboard_arrow_right

    Multiplicity fluctuation provides enough information concerning the dynamics of particle production process and even signature of phase transition from hadronic to QGP phase expected in ultrarelativistic nuclear collision. Numerous analyses reported on the fluctuation pattern of pions have been studied from theoretical and phenomenological approaches. Also the fractal properties have been explored to characterize quantitative […] keyboard_arrow_right
  • Non-invasive alarm generation for Sudden Cardiac Arrest – a pilot study with visibility graph technique
    Sudden cardiac arrest is a serious medical condition claiming numerous lives across the globe. The fact that in most cases the victim succumbs to death within an hour of the onset of symptoms itself indicates the dreadful nature of the disease. The comparative study of values obtained through the analysis of diseased and normal subjects […] keyboard_arrow_right
