    Sammanfattning : The contemporary computers typically consist of multiple computing cores with high compute power. Such computers make excellent concurrent asynchronous shared memory system. LÄS MER

  3. 2. From Declarative Models to Local Search

    Författare :Gustav Björdal; Pierre Flener; Justin Pearson; Laurent Michel; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; discrete optimisation; combinatorial optimisation; local search; large-neighbourhood search; MiniZinc; constraint programming; declarative modelling; declarative neighbourhoods; Computer Science; Datavetenskap;

    Sammanfattning : A solver is a general-purpose software for solving optimisation problems. It takes as input a description of a problem, called a model, and uses a collection of algorithms, called its solving technology, to ideally produce an optimal solution as output. Most solvers have a modelling language that cannot be processed by other solvers. LÄS MER

  4. 3. Contributions to Semantic Dependency Parsing : Search, Learning, and Application

    Författare :Robin Kurtz; Marco Kuhlmann; Lilja Øvrelid; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Semantic dependency parsing is the task of mapping natural language sentences into representations of their meaning in the form of directed graphs on words. These bilexical graphs are designed to capture the sentence-internal predicate-argument relationships – they tell us “who did what to whom” in the given sentence. LÄS MER

  5. 4. Voyage optimization algorithms for ship safety and energy-efficiency

    Författare :Helong Wang; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; Dijkstra’s algorithm; Voyage optimization algorithms; Genetic algorithm; Ship safety; Expected time of arrival;

    Sammanfattning : Currently, over 90% of the world’s trade is transported by sea. The environmental impacts from shipping and societal challenges of human and property losses caused by ship accidents are pressuring the shipping industry for more energy efficiency and enhanced safety. LÄS MER

  7. 5. Active Noise Control of Enclosed Sound Fields Optimising the Performance

    Författare :Per Sjösten; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimising actuator and sensor positions; hybrid controller for anc; fast feedforward algorithm; multiple-error algorithm; active noise control; complex lms; multichannel feedforward algorithm; simulated annealing; mean-field annealing; multiple-reference controller;

    Sammanfattning : Active noise control is the art of reducing a primary unwanted sound field by interference with an actively created secondary sound field. To achieve high reduction, it is crucial to obtain both temporal and spatial matching between the primary and the secondary sound fields. LÄS MER
