- How our brain sees objects in 3-D
- Neuroscientists at Johns Hopkins University JHU have discovered how we see objects in depth. Even if computers are better than humans in chess games, they can't beat us in the field of object recognition. This JHU research work 'suggests that higher-level visual regions of the brain represent objects as spatial...

- Online Client-Server Load Balancing Without Global Information
- A distributed online algorithm is considered for maximizing throughput in a network of clients and servers, modeled as a bipartite graph. Unlike most prior work on online load balancing, it do not assume centralized control and seek algorithms and lower bounds for decentralized algorithms in which each participant has only...

- A Scalable Peer-to-Peer System for Music Content and Information Retrieval
- Currently a large percentage of Internet traffic consists of music files, typically stored in MP3 compressed audio format, shared and exchanged over Peer-to-Peer (P2P) networks. Searching for music is performed by specifying keywords and naive string matching techniques. In the past years the emerging research area of Music Information Retrieval...

- Scaling Byzantine Fault-Tolerant Replication to Wide Area Networks
- This paper presents the first hierarchical Byzantine fault-tolerant replication architecture suitable to systems that span multiple wide area sites. The architecture confines the effects of any malicious replica to its local site, reduces message complexity of wide area communication, and allows read-only queries to be performed locally within a site...
