A functional central limit theorem for a class of urn models
We construct an independent increments Gaussian process associated to a class
of multicolor urn models. The construction uses random variables from the urn
model which are different from the random variables for which central limit
theorems are available in the two color case.Comment: 6 page
Structure and dynamics of premixed flames in microgravity
In this report we describe the research performed at the Naval Research Laboratory in support of the NASA Microgravity Science and Applications Program over the past three years with emphasis on the work performed since February 1992, the beginning of the current project. The focus of our research has been on investigating fundamental combustion questions concerning the propagation and extinction of gas-phase flames in microgravity and earth-gravity environments. Our approach to resolving these fundamental questions has been to use detailed time-dependent, multidimensional numerical models to perform carefully designed computational experiments. The basic questions we have addressed, a general description of the numerical approach, and a summary of the results are described in this report. More detailed discussions are available in the papers published which are referenced herein
