The Hybrid-Layer Index: A synergic approach to answering top-k queries in arbitrary subspaces
In this paper, we propose the Hybrid-Layer Index (simply, the HL-index) that is designed to answer top-k queries efficiently when the queries are expressed on any arbitrary subset ...

Programming asynchronous layers with CLARITY
Asynchronous systems components are hard to write, hard to reason about, and (not coincidentally) hard to mechanically verify. In order to achieve high performance, asynchronous c...

Guaranteeing the network lifetime in wireless sensor networks: A MAC layer approach
Energy is the most crucial but scarce resource in wireless sensor networks (WSNs). A wealth of MAC protocols are proposed only to prolong the network lifetime for energy-efficienc...

Fast optical layer mesh protection using pre-cross-connected trails
Conventional optical networks are based on SONET rings, but since rings are known to use bandwidth inefficiently, there has been much research into shared mesh protection, which pr...

DeMIMA: A Multilayered Approach for Design Pattern Identification
Design patterns are important in object-oriented programming because they offer design motifs, elegant solutions to recurrent design problems, which improve the quality of software...
