    Effects of carbides on fatigue characteristics of austempered ductile iron

    No full text
    Crack initiation and growth behavior of an austempered ductile iron (ADI) austenitized at 800 °C and austempered at 260 °C have been assessed under three-point bend fatigue conditions. Initiation sites have been identified as carbides remaining from the as-cast ductile iron due to insufficient austenization. The number of carbides cracking on loading to stresses greater than 275 MPa is critical in determining the failure mechanism. In general, high carbide area fractions promote coalescence-dominated fatigue crack failure, while low area fractions promote propagation-dominated fatigue crack failure. Individual carbides have been characterized using finite body tessellation (FBT) and adaptive numerical modeling (SUpport vector Parsimonious ANalysis Of VAriance (SUPANOVA)) techniques in an attempt to quantify the factors promoting carbide fracture. This indicated that large or long and thin carbides on the whole appear to be susceptible to fracture, and carbides that are locally clustered and aligned perpendicular to the tensile axis are particularly susceptible to fracture

    FNT-based reed-solomon erasure codes

    This paper presents a new construction of Maximum-Distance Separable (MDS) Reed-Solomon erasure codes based on Fermat Number Transform (FNT). Thanks to FNT, these codes support practical coding and decoding algorithms with complexity O(n log n), where n is the number of symbols of a codeword. An open-source implementation shows that the encoding speed can reach 150Mbps for codes of length up to several 10,000s of symbols. These codes can be used as the basic component of the Information Dispersal Algorithm (IDA) system used in a several P2P systems

    The use of reed canary-grass (Phalaris arundinacea) as a short fibre raw material for the pulp and paper industry

    No full text
    This thesis describes the use of delayed harvested reed canary-grass (Phalaris arundinacea) as a short fibre raw material for the pulp and paper industry. This study examines the following aspects of reed canary-grass: quality, transportation, storage, refining of the raw material by dry fractionation, chemical pulping, bleaching and paper production. The delayed harvesting method of reed canary-grass produces an economically and environmentally sustainable short fibre raw material for the pulp and paper industry. The ash content and fibre properties of reed canary-grass depend on soil type and growing location. The yearly variation in fibre yield and fibre properties is also considerable. There is, however, a potential for minimising quality variations by choosing reed canary-grass varieties suitable to a specific growing location. The leaf and leaf sheath content of reed canary-grass also affects the quality of the pulp. These quality variations can be eliminated by dry fractionation, a method that removes the unwanted parts of the grass. These unwanted parts can be used as a valuable bio-fuel raw material. Transport of reed canary grass after fractionation can be improved by briquetting, a method that doubles the transport capacity of reed canary-grass compared to that of birch logs on a fibre basis. High quality short fibre chemical pulp can be produced from reed canary-grass. The whole process from grass production to pulp production has been demonstrated successfully in full scale. Bleached reed canary-grass pulp can be used in products such as fine paper and white-top liner paper

    Reed Hall (2001)

    A photograph of Reed Hall on the campus of Springfield College, seen across a green field. International Hall can be seen to the right.Construction began on David Allen Reed Hall on August 1st, 1961 and was completed on September 1st, 1962. The dedication took place on October 20th, 1962. The building was originally to be named Massasoit Hall, but was changed to Reed Hall when the trustees decided that the last dormitory constructed in the tri-pod of dormitories (Massassoit Hall and Lakeside Hall) built at that time should be named after the College’s founder in order to allow time to collect proper funds in his name. Reed Hall was originally built as an all male dormitory housing 155 students, but today is coed, housing first years or freshmen.On the back is stamped "July 2001 <No.13A.023 329 60** N N N-1-04 2(023)"

    Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Engenharia Elétrica, Florianópolis, 2014.Atualmente, diversos sistemas de comunicação demandam grandes volumes de tráfego de dados para consumo quase instantâneo. Estes dados devem ser entregues aos usuários tal qual foram gerados: sem erros. Por isso, técnicas de controle e correção de erros estão intrinsecamente ligadas aos sistemas que realizam trocas de dados, sejam sistemas de armazenamento, os quais estão sujeitos a falhas durante a leitura, ou sistemas de comunicação, que estão sujeitos às adversidades do meio (radiação, interferência eletromagnética, desvanecimento, entre outros). Neste cenário, os códigos Reed-Solomon representam uma solução viável para inúmeras aplicações, bem como pesquisas acadêmicas, mesmo tanto tempo após sua invenção. Este trabalho realiza um estudo da teoria que embasa os códigos Reed-Solomon, assim como implementa as técnicas do estado-da-arte dos módulos que compõem tanto o codificador quanto o decodificador, as quais são prototipadas em hardware reconfigurável.<br

    Reed-solomon forward error correction (FEC) schemes, RFC 5510

    No full text
    This document describes a Fully-Specified Forward Error Correction (FEC) Scheme for the Reed-Solomon FEC codes over GF(2^^m), where m is in {2..16}, and its application to the reliable delivery of data objects on the packet erasure channel (i.e., a communication path where packets are either received without any corruption or discarded during transmission). This document also describes a Fully-Specified FEC Scheme for the special case of Reed-Solomon codes over GF(2^^8) when there is no encoding symbol group. Finally, in the context of the Under-Specified Small Block Systematic FEC Scheme (FEC Encoding ID 129), this document assigns an FEC Instance ID to the special case of Reed-Solomon codes over GF(2^^8). Reed-Solomon codes belong to the class of Maximum Distance Separable (MDS) codes, i.e., they enable a receiver to recover the k source symbols from any set of k received symbols. The schemes described here are compatible with the implementation from Luigi Rizzo
