  1. 1. Non-parametric methods for functional data

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  3. 3. An approach to systems engineering tool data representation and exchange

    Author : Erik Herzog; Anders Törne; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; engineering processes; information systems; data exchange; data representation; COTS; Information technology; Informationsteknologi;

    Abstract : Over the last decades computer based tools have been introduced to facilitate systems engineering processes. There are computer based tools for assisting engineers in virtually every aspect of the systems engineering process from requirement elicitation and analysis, over functional analysis, synthesis, implementation and verification.

  4. 4. Advances in Functional Decomposition: Theory and Applications

    Author : Andrés Martinelli; Elena Dubrova; Jon Muzio; Andres Martinelli; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; computer science; electronic system design; Boolean decomposition; binary decision diagram; logic synthesis; graph algorithm; Computer science; Datavetenskap;

    Abstract : Functional decomposition aims at finding efficient representations for Boolean functions. It is used in many applications, including multi-level logic synthesis, formal verification, and testing. This dissertation presents novel heuristic algorithms for functional decomposition.

  5. 5. Protecting Functional Programs From Low-Level Attackers

    Author : Adriaan Larmuseau; Dave Clarke; Julian Rathke; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Security; Functional Programming; Compilation; Interoperation; Bisimulation; Memory Protection; Datavetenskap; Computer Science;

    Abstract : Software systems are growing ever larger. Early software systems were singular units developed by small teams of programmers writing in the same programming language. Modern software systems, on the other hand, consist of numerous interoperating components written by different teams and in different programming languages. READ MORE
