Power efficient comparators for long arguments in superscalar processors
Traditional pulldown comparators that are used to implement associativeaddressing logic in superscalar microprocessors dissipate energy on a mismatch in any bit position in the co...

Cache-oblivious shortest paths in graphs using buffer heap
We present the Buffer Heap (BH), a cache-oblivious priority queue that supports Delete-Min, Delete, and Decrease-Key operations in O( 1 B log2 N B ) amortized block transfers fro...

Segmentation and Probabilistic Registration of Articulated Body Models
There are different approaches to pose estimation and registration of different body parts using voxel data. We propose a general bottom-up approach in order to segment the voxels...

Node-Weighted Steiner Tree and Group Steiner Tree in Planar Graphs
We improve the approximation ratios for two optimization problems in planar graphs. For node-weighted Steiner tree, a classical network-optimization problem, the best achievable ap...

Secrecy in Multiagent Systems
We introduce a general framework for reasoning about secrecy requirements in multiagent systems. Because secrecy requirements are closely connected with the knowledge of individua...
