| 1 |  | Carter, John | A collective approach to harness idle resources | We propose a collective approach for harnessing the idle resources (cpu, storage, and bandwidth) of nodes (e.g., home desktops) distributed across the Internet. Instead of a purely peer-to-peer (P2P) approach, we organize participating nodes to act collectively using collective managers (CMs). Pa... | Idle resources; Computer nodes | 2008 |

John; Nilsson, Michael | Adaptive gain processing to improve feedback cancellation in digital hearing aids | Adaptive filters are commonly used to cancel acoustic feedback in hearing aids.
