  2. 1. Metamathematical fixed points

    Author : Rasmus Blanck; Göteborgs universitet; []
    Keywords : HUMANIORA; HUMANITIES; arithmetised metamathematics; fixed point; recursion theory;

    Abstract : This thesis concerns the concept of metamathematical fixed points. After an introduction, we survey the field of metamathematics, from la fin du siècle to present. We are especially interested in the notion of fixed points, theorems on the existence of various kinds of fixed points, and their applications to metamathematics. READ MORE

  4. 2. Residue fixed point index and wildly ramified power series

    Author : Jonas Nordqvist; Karl-Olof Lindahl; Robert Laurent Benedetto; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; wildly ramified power series; residue fixed point index; formal invariant; iterative residue; ramification numbers; non-archimedean; discrete dynamical systems; arithmetic dynamics; periodic points; Nottingham group; Mathematics; Matematik;

    Abstract : This thesis concerns discrete dynamical systems. These are systems where the dynamics is modeled by iterated functions. There are several applications of discrete dynamical system e.g. READ MORE

  5. 3. Fixed Point Iterations for Finite Sum Monotone Inclusions

    Author : Martin Morin; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; monotone inclusions; operator splitting;

    Abstract : This thesis studies two families of methods for finding zeros of finite sums of monotone operators, the first being variance-reduced stochastic gradient (VRSG) methods. This is a large family of algorithms that use random sampling to improve the convergence rate compared to more traditional approaches. READ MORE

  6. 4. Improving the Schedulability of Real Time Systems under Fixed Preemption Point Scheduling

    Author : Filip Markovic; Jan Carlson; Radu Dobrin; Björn Lisper; Sebastian Altmeyer; José Javier Gutiérrez; Christian Berger; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Real-Time Systems; Limited Preemptive Scheduling; Fixed Preemption Points Scheduling; Probabilistic response time analysis; Cache-Related Preemption Delay Analysis; Computer Science; datavetenskap;

    Abstract : During the past decades of research in Real-Time systems, non-preemptive scheduling and fully preemptive scheduling have been extensively investigated, as well as compared with each other. However, it has been shown that none of the two scheduling paradigms dominates over the other in terms of schedulability. READ MORE

  7. 5. Aspects of Fixed-point Implementation of Multiuser Detctors in WCDMA

    Author : Hongxia Zhao; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Wideband code-division multiple-access (WCDMA) has been selected as the radio technique standard for the 3G mobile communication systems. However, it is well known that the conventional single-user detector, which is commonly used in CDMA systems, suffers from multiple-access interference (MAI). READ MORE
