  2. 6. Mutual Understanding in Situated Interactions with Conversational User Interfaces : Theory, Studies, and Computation

    Author : Dimosthenis Kontogiorgos; Joakim Gustafsson; Gabriel Skantze; Catherine Pelachaud; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; human-computer interaction; social robots; smart-speakers; multimodal behaviours; social signal processing; common ground; dialogue and discourse; joint-construction tasks; embodiment; conversational failures; Computer Science; Datalogi;

    Abstract : This dissertation presents advances in HCI through a series of studies focusing on task-oriented interactions between humans and between humans and machines. The notion of mutual understanding is central, also known as grounding in psycholinguistics, in particular how people establish understanding in conversations and what interactional phenomena are present in that process.

  4. 7. Feature Extraction for Low-Frequency Signal Classification

    Author : José Chilo; Thomas Lindblad; Christian Bohm; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; infrasound; seismic signals; feature extraction; wavelets; fingerprints; mining; multimodal data space; Atomic physics; Atomfysik; Electronics;

    Abstract : The development of the International Monitoring System (IMS) for the verification of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) has led to a rapid revival of interest in infrasound. Furthermore, the installation of low-frequency sensors at seismic sites has increased in recent years, providing researchers with large and heterogeneous data-sets in near real-time. READ MORE

  5. 8. Who is laughing now? Laughter-infused dialogue systems

    Author : Vladislav Maraev; Göteborgs universitet; []
    Keywords : HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; laughter; dialogue systems; humour; machine learning; reasoning; natural language processing; artificial agents;

    Abstract : This thesis paves the way for including laughter in spoken dialogue systems in a domain-general and linguistically valid way using computational linguistics tools and methods. The thesis is concerned with three main areas. The first area concerns the placement of laughter in relation to speech and other behaviours. READ MORE

  6. 9. Dopamine, decision-making, and aging : neural and behavioural correlates

    Author : Lieke de Boer; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : On any given day, we make tons of decisions. These can be as simple as deciding how to dress or what to eat, or more complex, such as whether to spend or invest money. Good decision-making involves being able to select the best alternative from a range of options, and adjust one’s preferences based on what is happening in the environment. READ MORE

  7. 10. Neuroblastoma as a target for effector mechanisms of the immune system

    Author : Anna De Geer; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Neuroblastoma (NB) is the most common solid extracranial tumor in children. Despite intensive multimodal treatment, the prognosis for high-risk NB patients remains poor and therefore new treatment modalities are needed. The main aim of my studies was to assess NB as a target for cytotoxic T lymphocyte (CTL)-mediated immunotherapy. READ MORE
