Hierarchical Temporal Memory: How a New Theory of Neocortex May Lead to Truly Intelligent Machines
Online Presentations | 12 Dec 2007 | Contributor(s):: Jeff Hawkins
Coaxing computers to perorm basic acts of perception and robotics, let alone high-level thought, has been difficult. No existing computer can recognize pictures, understand language, or navigate through a cluttered room with anywhere near a child's facility. Following nature's example, Jeff...

Computing the Horribleness of Soft Condensed Matter
Online Presentations | 19 Oct 2007 | Contributor(s):: Eric Jakobsson
A great triumph of computer simulations 40 years ago was to make the liquid state of matter understandable in terms of physical interactions between individual molecules. Prior to the first simulations of liquid argon and liquid water in the 1960's, there was no quantitatively rigorous molecular...

MCW07 Electronic Level Alignment at Metal-Molecule Contacts with a GW Approach
Online Presentations | 05 Sep 2007 | Contributor(s):: Jeffrey B. Neaton
Most recent theoretical studies of electron transport in single-molecule junctions rely on a Landauer approach, simplified to treat electron-electron interactions at a mean-field level within density functional theory (DFT). While this framework has proven relatively accurate for certain systems,...

SUGAR: the SPICE for MEMS
Online Presentations | 21 May 2007 | Contributor(s):: Jason Clark
In this seminar, I present some design, modeling, and simulation features of a computer aided engineering tool for microelectromechanical systems (MEMS) called SUGAR. For experimental verification, I use a microdevice that is difficult to simulate with conventional MEMS software. I show that...

Modeling and Analysis of VLSI Interconnects
Online Presentations | 10 May 2007 | Contributor(s):: Cheng-Kok Koh
With continual technology scaling, the accurate and efficient modeling and simulation of interconnect effects have become problems of central importance. In order to accurately model the distributive effects of interconnects, it is necessary to divide a long wire into several segments, with each...

Surprises on the nanoscale: Plasmonic waves that travel backward and spin birefringence without magnetic fields
Online Presentations | 08 Jan 2007 | Contributor(s):: Daniel Neuhauser
As nanonphotonics and nanoelectronics are pushed down towards the molecular scale, interesting effects emerge. We discuss how birefringence (different propagation of two polarizations) is manifested and could be useful in the future for two systems: coherent plasmonic transport of near-field...
