We present the results of a spectral study of the soft X-ray emission (0.2−2.5 keV) from low-latitude (‘disk’) regions of Jupiter. The data were obtained during two observing campaigns with XMM-Newton in April and November 2003. While the level of the emission remained approximately the same between April and the first half of the November observation, the second part of the latter shows an enh...

a new approach utilizing newton method and homotopy analysis method (ham) is proposed for solving nonlinear system of equations. accelerating the rate of convergence of ham, and obtaining a global quadratic rate of convergence are the main purposes of this approach. the numerical results demonstrate the efficiency and the performance of proposed approach. the comparison with conventional homoto...

We study several approaches to orbital optimization in selected configuration interaction (SCI) plus perturbation theory methods and test them on the ground excited states of three molecules using semistochastic heat-bath method. discuss ways which problem SCI resembles differs from that complete active space self-consistent field. Starting natural orbitals, these divide into classes according ...

in the present study, the mechanical behavior of aa5052 aluminum alloy during cold deformation and subsequent isothermal annealing in a temperature range of 225-300oc was investigated using the uniaxial tensile test data. it is found that by increasing the annealing time and temperature the material yield strength is decreased. the microstructural investigations of the annealed samples show tha...

In this paper, we present a full Newton step feasible interior-pointmethod for circular cone optimization by using Euclidean Jordanalgebra. The search direction is based on the Nesterov-Todd scalingscheme, and only full-Newton step is used at each iteration.Furthermore, we derive the iteration bound that coincides with thecurrently best known iteration bound for small-update methods.

This paper presents a new numerical approach to the simulation of plasma equilibrium evolution in tokamaks. It is based on an unusual coupling formulation current diffusion and axi-symmetric equations that does not require use flux-surface averages allows for fast Newton-type iterations schemes. A detailed derivation coupled system non-linear its discretization provided. Numerical examples, imp...

We propose a new formulation of the Wigner transport equation (WTE) with infinite correlation length. Since maximum length is not limited to finite value, there no uncertainty in simulation results owing integral range nonlocal potential term. For general and efficient simulation, proposed WTE solved self-consistently Poisson through volume method fully coupled Newton–Raphson scheme. Through th...

Reactive transport plays an important role in various subsurface applications, including carbon dioxide sequestration, nuclear waste storage, biogeochemistry and the simulation of hydro–thermal reservoirs. The model couples a set partial differential equations, describing chemical species, to nonlinear algebraic or reactions. Solution methods for resulting large system can be either fully coupl...
