Estimation of Two Component Activities of Binary Liquid Alloys by the Pair Potential Energy Containing a Polynomial of the Partial Radial Distribution Function

open access: yesMetals, 2023
An investigation of pair partial radial distribution functions and molecular pair potentials within a system has established that the existing potential functions are rooted in the assumption of a static arrangement of atoms, overlooking their distribution and vibration.

Energy margin from time domain simulation using partial energy function

1994 Proceedings of Canadian Conference on Electrical and Computer Engineering, 1994
The value of the time domain simulation technique for power system transient stability analysis can be greatly enhanced if it can indicate the degree of stability by producing a stability index. Often referred to as energy margin, the stability index offers additional insight into the transient stability problem being studied, and has the capability of

Time dependent partial loss of the effects of isoproterenol on function and energy metabolism of isolated rat hearts

Basic Research in Cardiology, 1980
In isolated perfused rat hearts (medium: Krebs-Ringer solution containing about 15% bovine red cells) the following parameters were estimated: heart rate (F), left intraventricular peak pressure (P), dP/dt, oxygen consumption (VO2); myocardial tissue content of glycogen, ATP, ADP, AMP, cAMP, phosphocreatin (PC) and inorganic phosphate (Pi ...

Self-adaptive separation of multiple partial discharge sources based on optimized feature extraction of cumulative energy function

IEEE Transactions on Dielectrics and Electrical Insulation, 2017
Partial discharge (PD) measurement is an effective tool for insulation condition assessment of high-voltage power equipment. The occurrence of multiple PD sources causes great difficulty on pattern recognition and failure risk assessment. This paper presents a self-adaptive PD separation algorithm based on optimized feature extraction of cumulative ...

Finding Generalized Forces by Use of Partial Derivatives of Energy Functions

IEEE Transactions on Education, 1967
A general conservative system may be considered to be represented by n(generalized) ports at which energy can enter the system; two generalized variables are associated with each port, the generalized force variable and the generalized coordinate variable.

Analytic computation of energy derivatives. Relationships among partial derivatives of a variationally determined function

The Journal of Chemical Physics, 1986
This paper considers three functions of several variables, W(r,x), λ(r), and E(r), related by E(r)=W[r,λ(r)] and the condition that W(r,x) be stationary with respect to variations of x when x=λ. Formulas are presented which relate coefficients in the Taylor series expansions of these three functions. We call λ the response function. Partial derivatives

Excitation Energies from a Partially Spin-Restricted Wave Function

Computing Letters, 2007
A singe Slater determinant consisting of restricted and unrestricted, in spins, parts is proposed to construct a reference configuration for singlet excited states having the same symmetry as the ground one. A partially restricted Hartree-Fock approach is developed to derive amended equations determining the spatial molecular orbitals for singlet ...

Development of the quadrupole mass spectrometer with the Bessel–Box type energy analyzer: Function of the energy analyzer in the partial pressure measurements

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 2001
The quadrupole mass spectrometer (QMS) with the Bessel–Box type energy analyzer has been developed. The analyzer is placed between the ionizer and the quadrupole mass filter for the separation of the gas phase ions and the electron stimulated desorption (ESD) ions produced in the ionizer according to their kinetic energies.
