  1. 1. The Effects of Age of Onset on VOT in L2 Aquisition and L1 Attrition : A Study of the Speech Production and Perception of Advanced Spanish-Swedish Bilinguals

    Författare :Katrin Stölten; Niclas Abrahamsson; Ulla Sundberg; Kirk Sullivan; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; second language acquisition; first language attrition; maturational constraints; critical period; voice onset time; stop production; categorical perception; activation threshold hypothesis; L1 use; highly proficient L2 learners; L1 Spanish; L2 Swedish; Bilingualism; tvåspråkighet;

    Sammanfattning : This thesis explores the role of age in second language (L2) acquisition and first language (L1) attrition. The focus is on Voice Onset Time (VOT) in the production and categorical perception of word-initial L1 and L2 stops in highly advanced L1 Spanish learners of L2 Swedish. LÄS MER

  3. 2. Toward a Sustainable Human-Robot Collaborative Production Environment

    Författare :Abdullah Alhusin Alkhdur; Lihui Wang; Gunnar Bolmsjö; KTH; []
    Nyckelord :vision sensor; 3D image processing; collision detection; safety; robot; kinematics; dynamics; collaborative assembly; energy consumption; optimisation; manufacturing; Production Engineering; Industriell produktion;

    Sammanfattning : This PhD study aimed to address the sustainability issues of the robotic systems from the environmental and social aspects. During the research, three approaches were developed: the first one an online programming-free model-driven system that utilises web-based distributed human-robot collaboration architecture to perform distant assembly operations.

  4. 3. Search for Pair-Produced Supersymmetric Top Quark Partners with the ATLAS Experiment

    Författare :Yiming Abulaiti; Sara Strandberg; Kerstin Jon-And; Isabell Melzer-Pellmann; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ATLAS; supersymmetry; SUSY; Beyond Standard Model; stop; pMSSM; Large Hadron Collider; LHC; CERN; fysik; Physics;

    Sammanfattning : Searches for the supersymmetric partner of the top quark (stop) are motivated by natural supersymmetry, where the stop has to be light to cancel the large radiative corrections to the Higgs boson mass. This thesis presents three different searches for the stop at √s = 8 TeV and √s = 13 TeV using data from the ATLAS experiment at CERN’s Large Hadron Collider. LÄS MER

  5. 4. Human Fetal Hemoglobin : Biochemical Characterization and Recombinant Production

    Författare :Khuanpiroon Ratanasopa; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Blood substitutes; HBOCs; HbF; recombinant hemoglobin; pseudoperoxidase; ITC; haptoglobin;

    Sammanfattning : Blood transfusion is a common medical procedure when oxygen supply in the body is impaired. However, blood transfusion is not always without risks. The uncontrolled spreading of blood borne pathogens such as HIV or hepatitis B and C virus has urged researchers to look for “blood substitutes”. LÄS MER

  7. 5. A flexible real-time solution to modular design of an adaptive control system for turning

    Författare :Thomas Lundholm; Bo Lindström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turning; adaptive control; real-time control; Manufacturing engineering; Produktionsteknik;

    Sammanfattning : This thesis deals with the organization of an adaptive control system for turning and, furthermore, the development of an integration framework for subsystems in the adaptive control system. The thesis is organized in three main parts. LÄS MER
