A Survey of Self-Organization in Wireless Networks

January 1, 2007
Author(s)
Kevin L. Mills
This paper surveys recent research on self-organizing techniques applied to design and control large wireless ad hoc and sensor networks. The survey divides that research into five functional categories: (1) resource sharing, (2) structure formation and

A Time-Resolved Kinetic Monte-Carlo Simulation Study On Si (111) Etching

January 1, 2007
Author(s)
Hui Zhou, Joseph Fu, Richard M. Silver
In this paper we have extended the Kinetic Monte-Carlo simulation method to study the etching dynamics of Si (111) surfaces in NH4F in a time-resolved basis. We have examined the step-flow dynamics of Si(111) etching using various simulation window sizes

Acoustic Emission Source Location in a Thick Steel Plate Using Lamb Modes

January 1, 2007
Author(s)
Marvin A. Hamstad
Using a validated finite-element modeling code, buried out-of-plane (two dimensional code (2D)) and in-plane (three dimensional code (3D)) acoustic emission (AE) dipole point sources were operated at different depths below the top surface of a 25.4 mm (1

Adiabatic Domain Wall Motion and Landau-Lifshitz Damping

January 1, 2007
Author(s)
Mark D. Stiles, Wayne M. Saslow, Michael J. Donahue, A Zangwill
Recent theory and measurements of the velocity of current-driven domain walls in magnetic nanowires have re-opened the unresolved question of whether Landau-Lifshitz damping or Gilbert damping provides the more natural description of dissipative

Anisotropic Wetting on Tunable Micro-Wrinkled Surfaces

January 1, 2007
Author(s)
Jun Y. Chung, Jeffrey Youngblood, Christopher M. Stafford
We demostrate that the buckling instability technique is promising for studying wettability because key elements of surface topography such as surface roughness can be precisely controlled by simple changes in experimental conditions. For demonstration, we
