  1. 41. Dynamic Enforcement of Differential Privacy

    Författare :Hamid Ebadi Tavallaei; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; differential privacy;

    Sammanfattning : With recent privacy failures in the release of personal data, differential privacy received considerable attention in the research community. This mathematical concept, despite its young age (Dwork et al. LÄS MER

  3. 42. Optimizing and Approximating Algorithms for the Single and Multiple Agent Precedence Constrained Generalized Traveling Salesman Problem

    Författare :Raad Salman; Göteborgs universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PCGmTSP; GTSP; SOP; mTSP; branch and bound; asymmetric generalized multiple traveling salesman problem; VRP; PCGTSP; dynamic programming; sequential ordering problem; vehicle routing problem; ant colony optimization; metaheuristic local search heuristic; precedence constraints; edge exchange; ant colony optimization;

    Sammanfattning : In the planning phases of automated manufacturing, generating efficient programs for robot stations is a crucial problem which needs to be solved. One aspect of the programming is the optimization of task sequences, such as series of welds or measuring points, so that the cycle time is minimized. LÄS MER

  4. 43. Fuel-efficient and safe heavy-duty vehicle platooning through look-ahead control

    Författare :Valerio Turri; Karl H. Johansson; Nathan van de Wouw; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; platooning; eco-driving; look-ahead control; dynamic programming; distributed model predictive control; optimal control; autonomous vehicles; Electrical Engineering; Elektro- och systemteknik; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : The operation of groups of heavy-duty vehicles at small inter-vehicular distances, known as platoons, lowers the overall aerodynamic drag and, therefore, reduces fuel consumption and greenhouse gas emissions. Experimental tests conducted on a flat road and without traffic have shown that platooning has the potential to reduce the fuel consumption up to 10%. LÄS MER

  5. 44. Look-ahead control for fuel-efficient and safe heavy-duty vehicle platooning

    Författare :Valerio Turri; Karl H. Johansson; Petros Ioannou; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; platoon; platooning; optimization; optimal control; model predictive control; automatic control; fuel efficiency; intelligent transport systems; automated driving; cooperative; dynamic programming; trucks; heavy-duty vehicles; safe platooning; fuel-efficient platooning; distributed model predictive control; MPC; vehicle-following; pulse and glide; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : The operation of heavy-duty vehicles at small inter-vehicular distances, known as platoons, lowers the aerodynamic drag and, therefore, reduces fuel consumption and greenhouse gas emissions. Tests conducted on flat roads have shown the potential of platooning to reduce the fuel consumption of about 10%. LÄS MER

  7. 45. Probabilistic Models for Species Tree Inference and Orthology Analysis

    Författare :Ikram Ullah; Jens Lagergren; Arndt von Haeseler; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; phylogenetics; phylogenomics; gene tree; species tree; expectation maximization; mixture model; dynamic programming; markov chain monte carlo; PrIME; JPrIME; Datalogi; Computer Science;

    Sammanfattning : A phylogenetic tree is used to model gene evolution and species evolution using molecular sequence data. For artifactual and biological reasons, a gene tree may differ from a species tree, a phenomenon known as gene tree-species tree incongruence. Assuming the presence of one or more evolutionary events, e.g. LÄS MER
