  1. 1. Generalized Vandermonde matrices and determinants in electromagnetic compatibility

    Detta är en avhandling från Västerås : Mälardalen University

    Författare :Karl Lundengård; Sergei Silvestrov; Dietrich von Rosen; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Sammanfattning : Matrices whose rows (or columns) consists of monomials of sequential powers are called Vandermonde matrices and can be used to describe several useful concepts and have properties that can be helpful for solving many kinds of problems. In this thesis we will discuss this matrix and some of its properties as well as a generalization of it and how it can be applied to curve fitting discharge current for the purpose of ensuring electromagnetic compatibility.

  2. 2. Stochastic Modeling and Simulation of the TCP protocol

    Detta är en avhandling från Uppsala : Avdelningen för matematisk statistik

    Författare :Jörgen Olsén; Uppsala universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; TCP; flow-control; network simulator; ns-2; stochastic modeling; throughput; packet loss rate; fixed-point method; Matematisk statistik; MATHEMATICS Applied mathematics Mathematical statistics; MATEMATIK Tillämpad matematik Matematisk statistik;

    Sammanfattning : The success of the current Internet relies to a large extent on a cooperation between the users and the network. The network signals its current state to the users by marking or dropping packets. The users then strive to maximize the sending rate without causing network congestion. LÄS MER

  3. 3. Nelson-type Limits for α-Stable Lévy Processes

    Detta är en avhandling från Linnéuniversitet

    Författare :Haidar Al-Talibi; Astrid Hilbert; Francesco Russo; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ornstein-Uhlenbeck position process; α-stable Lévy noise; scaling limits; time change; stochastic Newton equations; MATHEMATICS Applied mathematics Mathematical statistics; MATEMATIK Tillämpad matematik Matematisk statistik; MATHEMATICS Applied mathematics; MATEMATIK Tillämpad matematik; Mathematics; Matematik;

    Sammanfattning : Brownian motion has met growing interest in mathematics, physics and particularly in finance since it was introduced in the beginning of the twentieth century. Stochastic processes generalizing Brownian motion have influenced many research fields theoretically and practically. LÄS MER

  4. 4. On Methods for Real Time Sampling and Distributions in Sampling

    Detta är en avhandling från Umeå : Matematisk statistik

    Författare :Kadri Meister; Daniel Thorburn; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; Finite population sampling; inferential issues; real time sampling; sequential sampling methods; negative sampling correlations; model-design-based inference; multivariate Bernoulli and multinomial designs; Matematisk statistik; MATHEMATICS Applied mathematics Mathematical statistics; MATEMATIK Tillämpad matematik Matematisk statistik; Mathematical Statistics; matematisk statistik;

    Sammanfattning : This thesis is composed of six papers, all dealing with the issue of sampling from a finite population. We consider two different topics: real time sampling and distributions in sampling. The main focus is on Papers A–C, where a somewhat special sampling situation referred to as real time sampling is studied. LÄS MER

  5. 5. Aspects of cash-flow valuation

    Detta är en avhandling från Stockholm : Matematik

    Författare :Fredrik Armerin; Boualem Djehiche; Bjarne Astrup Jensen; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; arbitrage; coherent and convex measures of risk; immunization; insurance; martingale methods; Matematisk statistik; MATHEMATICS Applied mathematics Mathematical statistics; MATEMATIK Tillämpad matematik Matematisk statistik;

    Sammanfattning : This thesis consists of five papers. In the first two papers we consider a general approach to cash flow valuation, focusing on dynamic properties of the value of a stream of cash flows. The third paper discusses immunization theory, where old results are shown to hold in general deterministic models, but often fail to be true in stochastic models. LÄS MER
