Aims. We investigate the dependence of the luminosity-diameter relation of galaxies on the environment. Methods. This study is based on a comparison between the 80 galaxies in the Shapley-Ames Catalog that are located within a distance of 10 Mpc, and the luminosity-diameter relation for galaxies in great clusters such as Virgo and Coma. Results. A relatively tight linear correlation is observed...

The AMES Wholesale Power Market Test Bed is an agent-based computational laboratory designed for the systematic experimental study of restructured wholesale power markets. These notes show how AMES can be recast in more standard state-space equation form. The result is a highly nonlinear and highly coupled system of first-order stochastic difference equations. The AMES state-space equation repr...

Three methods for representing data in a relational storage system with an in-core frame-based system are experimented with and reported upon. Tradeoffs among these three representational methods are sizes of databases, times for loading data, and performance of queries. Essentially, these methods differ in ways of capturing relationships among frames. The three different ways of capturing such...
