Analysis of Spatial Multiplexing for Cross-Layer Design of MIMO Ad Hoc Networks
— We consider the application of spatial multiplexing to ad hoc networks where nodes have multiple antennas. At the physical level, we suppose that layered space–time multiuser...

UMR: A Multi-Round Algorithm for Scheduling Divisible Workloads
In this paper we present an algorithm for scheduling parallel applications that consist of a divisible workload. Our algorithm uses multiple rounds to overlap communication and co...

Optimizing All-Nearest-Neighbor Queries with Trigonometric Pruning
Many applications require to determine the k-nearest neighbors for multiple query points simultaneously. This task is known as all-(k)-nearest-neighbor (AkNN) query. In this paper,...

Immersive Planar Display using Roughly Aligned Projectors
When a projector is oblique with respect to a planar displaysurface, it creates keystoning and the projected imageis distorted. We present a rendering technique to display perspec...

Surface reconstruction from unorganized points
We describe and demonstrate an algorithm that takes as input an unorganized set of points fx1; : : : ; xng IR3 on or near an unknown manifold M, and produces as output a simplicia...
