30 Aug 2009TL;DR: This paper proposes a checksum-based approach, which is well-suited to the unique characteristics of database provenance, including non-linear provenance objects and provenance associated with multiple fine granularities of data.
Abstract: Database provenance chronicles the history of updates and modifications to data, and has received much attention due to its central role in scientific data management. However, the use of provenance information still requires a leap of faith. Without additional protections, provenance records are vulnerable to accidental corruption, and even malicious forgery, a problem that is most pronounced in the loosely-coupled multi-user environments often found in scientific research.
This paper investigates the problem of providing integrity and tamper-detection for database provenance. We propose a checksum-based approach, which is well-suited to the unique characteristics of database provenance, including non-linear provenance objects and provenance associated with multiple fine granularities of data. We demonstrate that the proposed solution satisfies a set of desirable security properties, and that the additional time and space overhead incurred by the checksum approach is manageable, making the solution feasible in practice.

TL;DR: A common exchange format for multimodal annotation is proposed, based on the annotation graph (AG) formalism, which is supported by import and export routines in the respective tools, and can be reliably exchanged between the tools.
Abstract: This paper presents the results of a joint effort of a group of multimodality researchers and tool developers to improve the interoperability between several tools used for the annotation and analysis of multimodality. Each of the tools has specific strengths so that a variety of different tools, working on the same data, can be desirable for project work. However this usually requires tedious conversion between formats. We propose a common exchange format for multimodal annotation, based on the annotation graph (AG) formalism, which is supported by import and export routines in the respective tools. In the current version of this format the common denominator information can be reliably exchanged between the tools, and additional information can be stored in a standardized way.

TL;DR: In this paper, a simplified procedure is developed and proved to correct erasures as well as errors by replacing the initial condition of the Euclidean algorithm by the erasure locator polynomial and the Forney syndrome polynomials.
Abstract: It is well known that the Euclidean algorithm or its equivalent, continued fractions, can be used to find the error locator polynomial and the error evaluator polynomial in Berlekamp's key equation needed to decode a Reed-Solomon (RS) code. A simplified procedure is developed and proved to correct erasures as well as errors by replacing the initial condition of the Euclidean algorithm by the erasure locator polynomial and the Forney syndrome polynomial. By this means, the errata locator polynomial and the errata evaluator polynomial can be obtained, simultaneously and simply, by the Euclidean algorithm only. With this improved technique the complexity of time domain RS decoders for correcting both errors and erasures is reduced substantially from previous approaches. As a consequence, decoders for correcting both errors and erasures of RS codes can be made more modular, regular, simple, and naturally suitable for both VLSI and software implementation. An example illustrating this modified decoding procedure is given for a (15, 9) RS code.

01 Dec 1998TL;DR: The Detailed Policy Assessment Tool (DPAT) is a widely used simulation of air traffic control that incorporates advanced technology for user-friendly operation that computes congestion-related air traffic delays, throughputs, traffic densities, and arrival/departure schedules while incorporating ground delay and ground stop programs.
Abstract: The Detailed Policy Assessment Tool (DPAT) is a widely used simulation of air traffic control that incorporates advanced technology for user-friendly operation. DPAT computes congestion-related air traffic delays, throughputs, traffic densities, and arrival/departure schedules while incorporating ground delay and ground stop programs, in-trail restrictions, historical, current, or future traffic demand, a fixed or free-flight route structure, and other relevant parameters. DPAT's advanced capabilities include parallel discrete-event simulation technology and easy access through Web-based simulation.
