Studies in one dimension of the quantum crystal problem
(1961)
Various methods proposed for the quantum crystal problem are studied in one dimension, using a simple linear lattice whose particle mass, spacing, and Lennard-Jones potential parameters are chosen as the values for a normal ...
A theoretical method for representing the gas dynamic forces and convective heat transfer properties for concave bodies in high speed rarefied gases
(1961)
An analysis is performed on concave surfaces in high speed rarefied gases where the surfaces are oriented at an arbitrary angle of attack. A general procedure is presented for representing the force and heat transfer ...
A sequentially transforming conjugate gradient algorithm
(1961)
The field of nonlinear programming has witnessed a tremendous growth in the last several years. However, to some extent, nonlinear programming exists as an experimental field of research, advancing through the study of ...
The economic effects of regulated automobile insurance rates
(1961)
Most models concerning automobile insurance regulations lack the ability to empirically determine the relation between regulated and competitive insurance prices. The model developed in this study, by introducing a regulated ...
The distribution of euphausiids in the oceanic Gulf of Mexico, the Yucatan Strait, and the Northwest Caribbean
(1961)
A quasi-synoptic study is made of 27 species of euphausiids from the oceanic waters of the Gulf of Mexico, Yucatan Strait, and Northwest Caribbean. One species, Thysanopoda acutifrons is reported for the first time. Samples ...
On the dynamic structure of a tornado vortex near the ground
(1961)
The dynamic structure of a tornado vortex near the ground has been investigated by numerically solving the anelastic system of hydrodynamic equations with appropriate boundary conditions. The vertical and tangential velocity ...
Effect of tissue extract on healing of experimental burn ulcers
(1961)
Tissue extracts from subcutaneous tissue of albino rats subjected to massive lower limb scalds were demonstrated, upon intraperitoneal injection on the seventh day of healing, to alter the healing process in locally induced ...
A new approach to the estimation of variance components
(1961)
Consideration is given to obtaining maximum-likelihood estimates of variance components for both balanced and unbalanced data. The tool which allows this is the inverse of the variance-covariance matrix which is given for ...
