  1. 1. Complexities of Parsing in the Presence of Reordering

    Författare :Martin Berglund; Frank Drewes; Bruce Watson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; parsing; membership problems; complexity theory; reordering; shuffle; mildly context-sensitive; formal languages; Computer Science; datalogi;

    Sammanfattning : The work presented in this thesis discusses various formalisms for representing the addition of order-controlling and order-relaxing mechanisms to existing formal language models. An immediate example is shuffle expressions, which can represent not only all regular languages (a regular expression is a shuffle expression), but also features additional operations that generate arbitrary interleavings of its argument strings.

  4. 3. Text Harmonization Strategies for Phrase-Based Statistical Machine Translation

    Författare :Sara Stymne; Lars Ahrenberg; Joakim Nivre; Nizar Habash; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; Statistical machine translation; text harmonization; compound words; definiteness; reordering; unknown words;

    Sammanfattning : In this thesis I aim to improve phrase-based statistical machine translation (PBSMT) in a number of ways by the use of text harmonization strategies. PBSMT systems are built by training statistical models on large corpora of human translations. This architecture generally performs well for languages with similar structure. LÄS MER

  5. 4. Transport-Layer Performance in Wireless Multi-Hop Networks

    Författare :Jonas Karlsson; Andreas Kassler; Yan Zhang; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TCP; MPTCP; transport protocols; packet aggregation; multi-path routing; reordering; wireless multi-hop networks; tactical MANET; mobile ad hoc networks; wireless mesh networks; Computer Science; Datavetenskap;

    Sammanfattning : Wireless communication has seen a tremendous growth in the last decades. Continuing on this trend, wireless multi-hop networks  are nowadays used or planned for use in a multitude of contexts, spanning from Internet access at home to emergency situations. LÄS MER

  7. 5. Algorithms and Library Software for Periodic and Parallel Eigenvalue Reordering and Sylvester-Type Matrix Equations with Condition Estimation
