abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...

We show that there are strong relationships between approaches to optmization and learning based on statistical physics or mixtures of experts. In particular, the EM algorithm can be interpreted as converging either to a local maximum of the mixtures model or to a saddle point solution to the statistical physics system. An advantage of the statistical physics approach is that it naturally gives...

Modern holism is an approach which tries to cover weaknesses of atomism in mechanically describing the world. Modern and pre-modern holisms are generally conceived to be similar. This paper mainly seeks to find if there is any similarity between architecture based on modern and pre-modern holism and, if yes, to what extent should we seek their similarities and differences. The hypothesis is tha...

In this paper, Newton Harmonic Balance Method (NHBM) is applied to obtain the analytical solution for an electron beam injected into a plasma tube where the magnetic field is cylindrical and increases towards the axis in inverse proportion to the radius. Periodic solution is analytically verified and consequently the relation between the Natural Frequency and the amplitude is obtained in an ana...

abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...

Abstract We present a novel method for the solution of the diÆusion equation on a composite AMR mesh. This approach is suitable for including diÆusion based physics modules to hydrocodes that support ALE and AMR capabilities. To illustrate, we proÆer our implementations of diÆusion based radiation transport and heat conduction in a hydrocode called ALE-AMR. Numerical experiments conducted with ...

Control of magnetic levitation systems suffer from coupled physics regardless of control. Feedback control is used to robustly reject disturbances, but is complicated by this coupling. Improved performance is possible by decoupling dynamic disturbance torque, an attractive solution provided by the physics-based control design methodology. Promising approaches include elimination of virtual-zero...
