In this research work an attempt has been made to minimize flank wear of uncoated carbide inserts while machining AISI 1045 steel by finite element analysis. Tool wear is the predominant factor that causes poor surface finish and is responsible for the dimensional accuracy of the machined surface. The quality of component produced decides the effectiveness and competitiveness of any manufacturi...

Book Review: Cryptonomicon, Volume 46, Number 11

Of course, cryptography is necessary for a project such as the data haven, and, as the title would imply, discussions of codes and ciphers run throughout the book. Mathematicians with a background in cryptanalysis might be especially interested in a new output-feedback mode stream cipher formally introduced in this book for the first time. The code is described in greater detail in an appendix ...

This article relies on data from the Panel Study of Income Dynamics matched to U.S. census data to explain the factors contributing to homeownership transitions for a sample of renters who first left their parents’ homes during the years 1978 through 1987. The article employs continuous time duration models to explain first-time homeownership transitions as a function of various individual and ...

group Aut(M). Stability and Diophantine Geometry A structure M is said to be unstable if it interprets a bipartite graph (P,Q,R) with the feature that for each n there are ai ∈ P and bi ∈ Q for i = 1, . . . , n such that R(ai, bj ) if and only if i < j. A complete theory is unstable if some (any) model is unstable. If M is unstable (witnessed by (P,Q,R) ) and saturated, then there are ai and bi...
