Nonlocal Variational Image Deblurring Models in the Presence of Gaussian or Impulse Noise
Abstract. We wish to recover an image corrupted by blur and Gaussian or impulse noise, in a variational framework. We use two data-fidelity terms depending on the noise, and sever...

Using Global Information for Load Balancing in DHTs
Distributed Hash Tables (DHT) with order-preserving hash functions require load balancing to ensure an even item-load over all nodes. While previous item-balancing algorithms only...

Inverse Kinematics for a Point-Foot Quadruped Robot with Dynamic Redundancy Resolution
— In this work we examine the control of center of mass and swing leg trajectories in LittleDog, a point-foot quadruped robot. It is not clear how to formulate a function to comp...
