Effects of Operating Temperature on the Characteristics of Nickel/Iron Traction Batteries

Description: Performance of improved Ni/Fe electric vehicle batteries was measured at ambient temperatures of 0, 25, and 50 C for a range of overcharge levels, open-circuit stand times, and charge and discharge rates. Tests in which charges and discharges were performed at different battery operating temperatures showed that the discharge capacity of a Ni/Fe battery is directly related to its operating temperature, but its charge acceptance is decreased at 0 and 50 C by approx. 6% from that obtained at 25 C… more

Mathematical Modeling and Evaluation of Radionuclide Transport Parameters from the ANL Laboratory Analog Program

Description: Computer model simulation is required to evaluate the performance of proposed or future high-level radioactive waste geological repositories. However, the accuracy of a model in predicting the real situation depends on how well the values of the transport properties are prescribed as input parameters. Knowledge of transport parameters is therefore essential. We have modeled ANL's Experiment Analog Program which was designed to simulate long-term radwaste migration process by groundwater flowing… more

Burner Stabilized Flames in Fluids

Description: In this report it is shown that a burner placed in a combustible fluid can have a stabilizing effect on a plane flame. A mathematical model is derived in which the flame is modeled as a surface of discontinuity in the flow field. Jump conditions for the fluid variables, as well as an expression for the flame speed, are obtained from an asymptotic analysis of the detailed structure of the flame. The model is applied to investigate the linear stability of a plane flame. Stable behavior is shown t… more

Improving the Accuracy of Computed Eigenvalues and Eigenvectors

Description: This paper describes a computational method for improving the accuracy of a given eigenvalue and its associated eigenvector. The method is analogous to iterative improvement for the solution of linear systems. An iterative algorithm using working precision arithmetic is applied to increase the accuracy of the eigenpair. The only extended precision computation is the residual calculation. The method is related to inverse iteration and to Newton's method applied to the eigenvalue problem.

Automatic Transformations in the Inference Process

Description: A technique for incorporating automatic transformations into processes such as the application of inference rules, subsumption, and demodulation provides a mechanism for improving search strategies for theorem proving problems arising from the field of program verification. The incorporation of automatic transformations into the inference process can alter the search space for a given problem, and is particularly useful for problems having broad rather than deep proofs. The technique can also b… more

REDUCE-Aided Study of a Problem in Hermitian Matrix Theory

Description: Let A be any n x n positive definite matrix and B any n x n non-negative definite matrix. In an earlier paper we showed that for each n there is a real number t/sub n/> 2 such that if t <t/sub n/ then the solution X of the matrix equation A²X + XA² + tAXA = B is non-negative definite. For n = 2, t₂ = infinity and for n = 3, t₃ = 8. In this report we show that t₄ = 4, t₅ <3.02048507 and t₆ <2.62120330.

Post-Test Analyses of Aqueous Batteries Developed for Electric Propulsion : Summary Report for January 1985-September 1986

Description: This document is a summary of the activities conducted on post-test examination of aqueous electric-vehicle batteries from January 1985 to September 1986. The post-test analyses were conducted to determine the causes of performance degradation (e.g., capacity decline, power loss, self-discharge) in lead-acid and nickel/iron batteries. For the lead-acid batteries, the primary causes of capacity decline were generally found to be morphological changes in the positive active material, corrosion of… more

Review of the Analyses of the Doppler-Effect Measurements in SEFOR (Southwest Experimental Fast Oxide Reactor)

Description: The SEFOR experimental results and the three original analyses are reviewed and discussed. The emphasis of the review is placed on aspects that are pertinent to a possible modern re-analysis of the experimental results. Looking at the analysis results in terms of zero and first order effects shows that the zero order effects, the Doppler constant of the two SEFOR cores, are obtained by the three analyses in satisfactory agreement. But the first order effects, but temperature variation of this D… more
