  1. 1. Authentication under Constraints

    Författare :Elena Pagnin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Security.; Distance-Bounding; Privacy; Biometrics; Anonymity; Authentication; Digital Signatures;

    Sammanfattning : Authentication has become a critical step to gain access to services such as on-line banking, e-commerce, transport systems and cars (contact-less keys). In several cases, however, the authentication process has to be performed under challenging conditions. LÄS MER

  3. 2. Assessing the Integration of Biomass Gasification-Based Production of Chemicals — Case Study of an Oxo Synthesis Plant

    Författare :Maria Arvidsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemicals production; biorefinery; gasification; syngas; oxo synthesis; process integration;

    Sammanfattning : The chemical industry sector is energy-intensive and highly dependent on fossil feedstock. The primary long-term option to reduce fossil feedstock dependence and greenhouse gas (GHG) emissions is to switch to renewable feedstock. LÄS MER

  4. 3. Holistic Grasping: Affordances, Grasp Semantics, Task Constraints

    Författare :Martin Hjelm; Danica Kragic; Markus Vincze; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; robotics; robotic grasping; grasping; cognition; embodied cognition; computer vision; machine learning; artificial intelligence; AI; Gaussian process; Gaussian process latent variable model; GPLVM; 3D vision; point cloud features; robotik; manipulation; datorseende; maskininlärning; artificiell intelligens; kognition; Computer Science; Datalogi;

    Sammanfattning : Most of us perform grasping actions over a thousand times per day without giving it much consideration, be it from driving to drinking coffee. Learning robots the same ease when it comes to grasping has been a goal for the robotics research community for decades. LÄS MER

  5. 4. The Interplay Between Selection And Constraints On Adaptive Divergence And Phenotypic Evolution

    Författare :Fabrice Eroukhmanoff; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Selection; Constraints; Adaptive Divergence; G-matrix; Gene Flow.; Speciation;

    Sammanfattning : Under natural or sexual selection, individuals with advantageous traits or combinations of traits will be more successful than their peers at surviving and/or reproducing. Provided these traits are heritable, meaning that they have a genetic basis, the traits combinations which are selected for, will increase in frequency in the population. LÄS MER

  7. 5. Analysis, synthesis and application of automaton-based constraint descriptions

    Författare :María Andreína Francisco Rodríguez; Justin Pearson; Pierre Flener; Christopher Jefferson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; constraint programming; constraint predicates; global constraints; automata; automaton-described constraint predicates; automaton-induced constraint decompositions; implied constraints; time-series constraints; transducers; automaton invariants; Computer Science; Datavetenskap;

    Sammanfattning : Constraint programming (CP) is a technology in which a combinatorial problem is modelled as a conjunction of constraints on variables ranging over given initial domains, and optionally an objective function on the variables. Such a model is given to a general-purpose solver performing systematic search to find constraint-satisfying domain values for the variables, giving an optimal value to the objective function. LÄS MER
