This technical report describes the Spice implementation of IGM based on the Ice tesseral P2P substrate. Spice employs advanced load distribution techniques—enabled by the unique features of Ice— to ensure fair loading of all peers and network links.
Surface nuclear magnetic resonance (surface-NMR) method is a well-known tool for determining the water-bearing layers and subsurface resistivity structure. Harmonic interference is an inevitable interference in surface-NMR measurements. Accurate estimation of harmonic interference parameters (i.e., fundamental frequency, phase and amplitude) leads to better retrieval of power-line harmonics and...
The purpose of this paper is an optimal control problem of temperature using the Newton based method and the finite element method. This method is based on the first and second order adjoint technique allowing to obtained a better approximation to the Newton line search direction. The formulation is based on the optimal control theory in which the performance function is expressed by the comput...
<span lang="EN-US">Fractional differential equations play a major role in expressing mathematically the real-world problems as they help attain good fit to experimental data. It is also known that fractional order controllers are more flexible than integer controllers. But when it comes numerical approximation of functions inaccuracies arise if conversion technique not chosen properly. So...
A novel technique for identifying soil parameters on-line while traversing with a tracked vehicle on unknown terrain is presented. This technique, based on the Newton Raphson method is used to identify unknown soil parameters. Comparing with the Least Square method, it shows that the Newton Raphson method is better in terms of prediction accuracy, computational speed, and robustness to initial ...
The computation of periodic orbits of nonlinear mappings or dynamical systems can be achieved by applying a root-finding method. To determine a periodic solution, an initial guess should be located within a proper area of the mapping or a surface of section of the phase space of the dynamical system. In the case of Newton or Newton-like methods these areas are the basins of convergence correspo...
Multilevel inverters (MLIs) have offered significant contributions toward the implementation of energy conversion units used in industry and renewable applications. However, switching devices MLIs are associated with power loss division problems. The pulsewidth modulation (PWM) techniques greatly influence peak, average, ripple values device junction temperature. Thermal tension may be raised d...
In this paper, we present an inexact full Newton optimization method for the full waveform inversion algorithm in the frequency domain which utilizes simultaneous sources based upon the phase encoding technique. Tests show that the full Newton minimization method achieves a high convergence rate and a reasonably accurate reconstruction of the model parameters. Taking advantage of a direct solve...
