In a Monte Carlo study of the two dimensional Ising system (of size 100 × 100) with nearest neighbour ferromagnetic interaction in the presence of a sinusoidally varying external magnetic field, we studied the variation of the hysteretic loop area (A) with frequency (f), amplitude (h0) of...

Using wavelet-based multiresolution analysis, this study investigates the effect of hydrogen addition on cyclic variability in a natural gas spark ignition engine. The engine is operated at 3000rpm, and a lean combustible mixture with excess air ratio of 1.4 is used. Three cases are examined:...

We have studied the transport in two random dimer models. The site energies are chosen randomly from a binary distribution, one pair at a time and the hopping terms (nearest neighbour only) are chosen to be either (i) a constant, or (ii) perfectly correlated to adjacent random site energies. In...

We study localization properties of a one-dimensional disordered system characterized by a random non-hermitean hamiltonian where both the randomness and the non-hermiticity arises in the local site-potential; its real part being random, and a constant imaginary part implying the presence of...

The dynamics of cycle-to-cycle variations (CCV) was investigated in a natural gas direct-injection spark-ignition engine. The method of continuous wavelet transform was used to analyze the time series of the indicated mean effective pressure (IMEP) and other combustion variables. The dominant...

The kinetic gas theory, like the two-agent money exchange model, recently introduced in the econophysics of wealth distributions, is revisited. The emergence of a Boltzmann–Gibbs-like distribution of money into Pareto's law in the tail of the distribution is examined in terms of a 2×2...

This work is primarily based on a recently proposed toy model by Thurner et al. (2010) [3] on Schumpeterian economic dynamics (inspired by the idea of economist Joseph Schumpeter [9]). Interestingly, punctuated equilibrium has been shown to emerge from the dynamics. The punctuated equilibrium...

The Kinetic Gas Theory like two-agent money exchange models, recently introduced in the Econophysics of Wealth distributions, are revisited. The emergence of Boltzmann-Gibbs like distribution of individual money to Pareto's law in the tail of the distribution is examined in terms of 2x2...

In our simplified description `wealth' is money ($m$). A kinetic theory of gas like model of money is investigated where two agents interact (trade) selectively and exchange some amount of money between them so that sum of their money is unchanged and thus total money of all the agents remains...
