  2. 1. Automatic Detection of Grammar Errors in Primary School Children's Texts. A Finite State Approach

    Author : Sylvana Sofkova Hashemi; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; grammar errors; spelling errors; punctuation; children s writing; Swedish; language checking; light parsing; finite state technology;

    Abstract : This thesis concerns the analysis of grammar errors in Swedish texts written by primary school children and the development of a finite state system for finding such errors. Grammar errors are more frequent for this group of writers than for adults and the distribution of the error types is different in children's texts. READ MORE

  4. 2. Translation as Linear Transduction : Models and Algorithms for Efficient Learning in Statistical Machine Translation

    Author : Markus Saers; Joakim Nivre; Anna Sågvall Hein; Dekai Wu; Kevin Knight; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; linear transduction; linear transduction grammar; inversion transduction; zipper finite-state automaton; zipper finite-state transducer; formal language theory; formal transduction theory; translation; automatic translation; machine translation; statistical machine translation; Computational linguistics; Datorlingvistik; Language technology; Språkteknologi; Computational Linguistics; Datorlingvistik;

    Abstract : Automatic translation has seen tremendous progress in recent years, mainly thanks to statistical methods applied to large parallel corpora. Transductions represent a principled approach to modeling translation, but existing transduction classes are either not expressive enough to capture structural regularities between natural languages or too complex to support efficient statistical induction on a large scale.

  5. 3. The interdependence of plastic behaviour and final properties of steel wire, analysed by the finite element method

    Author : Henrik Överstam; Magnus Jarl; Sven-Erik Lundberg; Chunhui Luo; Örebro universitet; []
    Keywords : Technology; FEM; defects; steel wire; wire drawing; rolling; forging; Teknikvetenskap; TECHNOLOGY; TEKNIKVETENSKAP; Maskinteknik; Mechanical Engineering;

    Abstract : The finite element method (FEM) has been used in order to study the interdependence of plastic behaviour and final properties in steel wire. Three processes metal forming have been studied: billet forging, wire rod rolling, and cold drawing. READ MORE

  6. 4. Microstructure model for Ti-6Al-4V used in simulation of additive manufacturing

    Author : Corinne Charles Murgau; Lars-Erik Lindgren; Niklas Järvstråt; Robert Pederson; Sören Sjöström; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Titanium alloy; Ti-6Al-4V; Welding; Metal deposition; Additive manufacturing; Wire feed; Finite Element Method; Microstructure model; Johnson-Mehl-Avrami- Kolmogorov; Thermally driven; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik; Material Mechanics;

    Abstract : This thesis is devoted to microstructure modelling of Ti-6Al-4V. The microstructure and the mechanical properties of titanium alloys are highly dependent on the temperature history experienced by the material. The developed microstructure model accounts for thermaldriving forces and is applicable for general temperature histories. READ MORE

  7. 5. Particle interactions at the nanoscale : From colloidal processing to self-assembled arrays

    Author : Bertrand Faure; Lennart Bergström; Albert Philipse; Stockholms universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Colloidal processing; nanoparticles; colloidal forces; titania; iron oxide; Hamaker constant; surface modification; rheology; Monte Carlo simulations; collective properties; superparamagnetism; finite-size effects; Materials Chemistry; materialkemi;

    Abstract : Nanostructured materials are the next generation of high-performance materials, harnessing the novel properties of their nanosized constituents. The controlled assembly of nanosized particles and the design of the optimal nanostructure require a detailed understanding of particle interactions and robust methods to tune them. READ MORE
