We present a non-dimensional gas-fed pulsed plasma thruster performance model. The analysis uses a circuit element discharge description and a snow-plow mass accumulation model with two non-dimensional parameters for an outer electrode geometry contour and an exponential mass distribution. Implementing a non-dimensional scheme is shown to reduce the number of free parameters in the equations fr...

The one-dimensional model of Lippincott and Schroeder for hydrogen bond has Been re-examined and it has been shown that O-H bond distance depends on repulsive van der Waals and attractive electrostatic potentials.it has been shown that constant b in the van der Waals repulsion potential is not transferable to all hydrogen bonds. The possibility of obtaining the semi-empircal parameters i...

Based on the study of dimensional characteristics reeds, a sprayer is proposed for treatment panicles reeds growing in elements irrigation system rice checks. The boom offered has an original shape, sprayers which are located along trajectory parabola, taking into account placement upper points across width channel and equipped with protective chamber device, made form Archimedes spiral pitch e...

High dimensional predictive regressions are useful in wide range of applications. However, the theory is mainly developed assuming that model stationary with time invariant parameters. This at odds prevalent evidence for parameter instability economic series, but theories models a small number covariates. In this paper, we present two L2 boosting algorithms estimating high which coefficients mo...

Non-equilibrium dynamics is omnipresent in nature and technology can exhibit symmetries order. In idealistic systems this universality well-captured by traditional models of dynamical systems. Realistic processes are often more complex. This work considers two paradigmatic complexities—canonical Kolmogorov turbulence interfacial Rayleigh-Taylor mixing. We employ invariant forms to assess very d...
