We see a world where personal system software is self-installing, self-configuring, self-personalizing, self-administering, and self-healing. In this world, personal system data is visible in a single name space regardless of " owning " application and data location, supports uniform non-procedural query, transactions, and security, is automatically backed up, is recoverable, and supports porta...

Provenance research has generally focused on issues with data collection and organization. Most approaches represent stored provenance data as a directed acyclic graph (DAG), where objects such as files and processes are nodes in the graph and directed edges specify ancestry relationships between them. While there has been some work addressing logical compression of these provenance graphs, eff...

The CLEO III experiment will collect on the order of 200 TB of data over the lifetime of the experiment. The challenges facing CLEO III are how to store such a large dataset. We will describe our experiences with Objectivity/DB on top of a Hierarchical Storage Manager.

Most data retrieval mechanisms in wireless sensor networks adopt a data-centric approach, in which data is identified directly by name rather than through the location of the node on which it is stored. Initial data-centric methods, such as directed diffusion and TinyDB/TAG, focused on the conveyance of data. One of the advantages of these algorithms is that they do not require pointto-point ro...

The distribution of audio information in disk format—sound stored as modulations in a flat surface—has had a long and successful track record. At first, analog signals were imprinted on shellac and then later vinyl platters. But recently, sound has been almost exclusively distributed as and replayed from digitally encoded data, molded into the surface of compact polymer disks. This migration wa...

Introduction With its omnipresent computers, all connected via the Internet, the Information Age has led to an explosion of information available to users. The decreasing cost of storing data, and the increasing storage capacities of the same small device footprint, have been key enablers of this revolution. While current storage needs are being met, storage technologies must continue to improv...

Abstract The current conventional maintenance methods for transmission and substation operation equipment are mainly used to extract fault data features by combining micro-network algorithms process data. lack of effective analysis characteristics leads poor results. In this regard, a power system multi-device status hierarchical method considering the age service is proposed. By accessing conf...
