  1. 1. 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

  2. 2. Hidden Markov models : Identification, control and inverse filtering

    Författare :Robert Mattila; Bo Wahlberg; Eric Moulines; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hidden markov models; system identification; method of moments; inverse filtering; abdominal aortic aneurysm; medical; markov decision process; structure; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The hidden Markov model (HMM) is one of the workhorse tools in, for example, statistical signal processing and machine learning. It has found applications in a vast number of fields, ranging all the way from bioscience to speech recognition to modeling of user interactions in social networks. LÄS MER

  3. 3. Lokal radio och TV : en analys av publikstruktur och deltagande

    Författare :Anders Lindblad; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; RADIO; LOCAL TELEVISION; AUDIENCE; PARTICIPATION; DEMOCRACY; PUBLIC ACCESS; NEIGHBOURHOOD RADIO; SWEDEN; CABLE TELEVISION;

    Sammanfattning : The background to the thesis is the decentralization trend which has led to the development of various forms of local radio and television in a number of countries, including Sweden. Common to all official statements regarding the emergence of local media is the theme that local media has a potential for strengthening democracy. LÄS MER

  4. 4. Non-local models in manufacturing simulations

    Författare :Olufunminiyi Abiri; Miguel Vaz; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Sammanfattning : Ductile fracture presents challenges with respect to material modelling andnumerical simulations of localization. The strain and damage localization maybe unwanted as it indicates a failure in the process or, as in the case ofmachining and cutting, a wanted phenomenon to be controlled. LÄS MER

  5. 5. Simplifications of non-local damage models
