  1. 1. Functional Polytypic Programming

    Författare :Patrik Jansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; algebraic datatypes; functional programming; programming languages; polytypic programming; generic programming;

    Sammanfattning : Many algorithms have to be implemented over and over again for different datatypes, either because datatypes change during the development of programs, or because the same algorithm is used for several datatypes. Examples of such algorithms are equality tests, pretty printers, and pattern matchers, and polytypic programming is a paradigm for expressing such algorithms. LÄS MER

  2. 2. Non-parametric methods for functional data

    Författare :Johan Strandberg; Sara Sjöstedt de Luna; Konrad Abramowicz; Lina Schelin; Charlotte Häger; Pedro Delicado; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; functional data analysis; testing; clustering; prediction; inference; bagging Voronoi strategy; kriging; dependency; matematisk statistik; Mathematical Statistics;

    Sammanfattning : In this thesis we develop and study non-parametric methods within three major areas of functional data analysis: testing, clustering and prediction. The thesis consists of an introduction to the field, a presentation and discussion of the three areas, and six papers. LÄS MER

  3. 3. Modeling financial volatility : A functional approach with applications to Swedish limit order book data

    Författare :Suad Elezovic; Xavier de Luna; Gunnar Rosenqvist; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Financial data; functional time series; multivariate generalized least squares; seemingly unrelated autoregression; Statistics; computer and systems science; Statistik; data- och systemvetenskap; ekonometri; Econometrics;

    Sammanfattning : This thesis is designed to offer an approach to modeling volatility in the Swedish limit order market. Realized quadratic variation is used as an estimator of the integrated variance, which is a measure of the variability of a stochastic process in continuous time. LÄS MER

  4. 4. Functional Programming for Securing Cloud and Embedded Environments

    Författare :Abhiroop Sarkar; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; trusted execution environment; real time; functional programming; runtime; information flow control; microcontrollers; functional reactive programming;

    Sammanfattning : The ubiquity of digital systems across all aspects of modern society, while beneficial, has simultaneously exposed a lucrative attack surface for potential adversaries and attackers. Consequently, securing digital systems becomes of critical importance. LÄS MER

  5. 5. Pure Functional Parsing - an advanced tutorial

    Författare :Peter Ljunglöf; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; context-free grammars; parsing algorithms; parser combinators; functional programming;

    Sammanfattning : Parsing is the problem of deciding whether a sequence of tokens is recognized by a given grammar, and in that case returning the grammatical structure of the sequence. This thesis investigates di erent aspects of the parsing problem from the viewpoint of a functional programmer. LÄS MER
