  1. 1. Functional understanding of space : Representing spatial knowledge using concepts grounded in an agent's purpose

    Författare :Kristoffer Sjöö; Patric Jensfelt; David Vernon; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spatial representation; autonomous robots; spatial understanding; semantic mapping; spatial relations; visual search; robot search;

    Sammanfattning : This thesis examines the role of function in representations of space by robots - that is, dealing directly and explicitly with those aspects of space and objects in space that serve some purpose for the robot. It is suggested that taking function into account helps increase the generality and robustness of solutions in an unpredictable and complex world, and the suggestion is affirmed by several instantiations of functionally conceived spatial models.

  3. 2. Spatial paths to holiness : Literary ‘Lived Spaces’ in Eleventh-Century Byzantine Saints’ Lives

    Författare :Myrto Veikou; Ingela Nilsson; Stephanos Efthyniadis; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Byzantine studies; spatial studies; Grekiska; Greek;

    Sammanfattning : This thesis explores literary spatialities, that is the notion of space and its agency in comprehending the deeper plot and meaning of two eleventh-century Byzantine hagiographical texts: the Life of St Lazaros from Mount Galesion, written by Gregory the Cellarer (Γρηγορίου του κελλαρίτη Βίος Λαζάρου τοῦ ἐν τῷ  Γαλησίῳ), and the Life of St Symeon the New Theologian, written by Niketas Stethatos (Νικήτα Στηθάτου Βίος Ἁγίου Συμεὼν τοῦ Νέου Θεολόγου). The study proposes a narratological inquiry of the broader meaning of ‘spatialities’ in Byzantine texts, which focuses on the employment of a ‘spatial’ language or ‘spatial’ narrative techniques and strategies.

  4. 3. Presence through actions : theories, concepts, and implementations

    Författare :Muhammad Sikandar Lal Khan; Shafiq ur Réhman; Haibo Li; Jiebo Luo; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Presence; Immersion; Computer mediated communication; Strong concept; Phenomenology; Philosophy; Biologically inspired system; Neck robot; Head pose estimation; Embodied interaction; Virtual reality headset; Social presence; Spatial presence; Face reconstruction retrieval; Telepresence system; Quality of interaction; Embodied telepresence system; Mona-Lisa gaze effect; eye-contact; design; design; Computer Science; datalogi; Computer Systems; datorteknik; datoriserad bildanalys; Computerized Image Analysis;

    Sammanfattning : During face-to-face meetings, humans use multimodal information, including verbal information, visual information, body language, facial expressions, and other non-verbal gestures. In contrast, during computer-mediated-communication (CMC), humans rely either on mono-modal information such as text-only, voice-only, or video-only or on bi-modal information by using audiovisual modalities such as video teleconferencing.

  5. 4. Spatial variability of geogenic contaminants in drinking water sources : Insights into hydrogeological controls, geospatial data for safe water supply and groundwater resource management

    Författare :J. Ijumulana; Prosun Bhattacharya; Felix Mtalo; Steve W. Lyon; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drinking water; geogenic contaminants; potentially toxic elements; fluoride; spatial analysis; spatial variability; Tanzania; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : The presence of geogenic contaminants in drinking water is a major health concern in many parts of the world. The interaction of groundwater with different rock types and sediments in the natural geochemical environment play an important role in controlling their mobility. LÄS MER

  7. 5. On flexible random field models for spatial statistics: Spatial mixture models and deformed SPDE models

    Författare :Anders Hildeman; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Spatial statistics; Significant wave height; Spatial mixture model; Stochastic partial differential equation; Log-Gaussian Cox process; Point process; Gaussian random field; Substitute-CT;

    Sammanfattning : Spatial random fields are one of the key concepts in statistical analysis of spatial data. The random field explains the spatial dependency and serves the purpose of regularizing interpolation of measured values or to act as an explanatory model. LÄS MER
