Homology flows, cohomology cuts
We describe the first algorithm to compute maximum flows in surface-embedded graphs in near-linear time. Specifically, given a graph embedded on a surface of genus g, with two spe...

Toward Goldilocks' pointing device: determining a "just right" gain setting for users with physical impairments
We designed and evaluated an agent that recommends a pointing device gain for a given user, with mixed success. 12 participants with physical impairments used the Input Device Age...

The Impact of Bit-Line Coupling and Ground Bounce on CMOS SRAM Performance
In this paper, we provide an analytical framework to study the inter-cell and intra-cell bit-line coupling when it is superimposed with the ground bounce effect and show how those...

A Better Approximation Ratio for the Vertex Cover Problem
We reduce the approximation factor for Vertex Cover to 2 − Θ( 1√ log n ) (instead of the previous 2 − Θ(log log n log n ), obtained by Bar-Yehuda and Even [2], and by Moni...

How to Find a Point on a Line Within a Fixed Distance
It is well known that on a line, a target point in unknown position can be found by walking a path at most 9 times as long as the distance from the start to the target point, in t...
