The Asymptotic Dimension of the First Grigorchuk Group is Infinity
We prove that the asymptotic dimension of the first Grigorchuk group is
infinity.Comment: 3 page
On asymptotic dimension of countable abelian groups
We compute the asymptotic dimension of the rationals given with an invariant
proper metric. Also, we show that a countable torsion abelian group taken with
an invariant proper metric has asymptotic dimension zero.Comment: 9 pages, 1 figure, AMSTe
Computer program for analysis of flow across a gas turbine seal
Computer program analyzes the flow /leakage/ across a sealing dam for the case of steady, laminar, subsonic, isothermal, compressible flow. The analysis considers both parallel sealing-dam surfaces and surfaces with small tilt angles
The Mathematics of Information Science
This paper describes a course, The Mathematics of Information Science, which was taught at Towson University in Spring 1998, 1999, and 2000. This course is the junior level interdisciplinary course of the Maryland Collaborative for Teacher Preparation program. The effectiveness of the course in teaching problem solving techniques and abstract mathematical ideas is documented. The students constructed their own knowledge from laboratory experiences involving digital logic circuits. They were subsequently challenged to abstract this knowledge and to find ways to solve progressively more difficult problems using these digital logic circuits. The mathematics of encoding and decoding information constituted the major mathematical content of the course. This course is shown to be effective in introducing prospective elementary and middle school teachers to abstract mathematical ideas and problem solving techniques
