  2. 1. Driver modeling: Data collection, model analysis, and optimization

    Author : Ola Benderius; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driving simulator; driver modeling; stochastic optimization; simulation software; genetic algorithm;

    Abstract : This thesis concerns aspects of driver modeling, with an emphasis on critical near-crash scenarios, involving time spans of around 10 s of driving. Here,driver modeling has been studied using both computer simulations and experiments carried out in a high-fidelity driving simulator. READ MORE

  5. 3. Detection for multiple input multiple output channels : analysis of sphere decoding and semidefinite relaxation

    Author : Joakim Jaldén; Björn Ottersten; Zhi-Quan Luo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telekommunications; MIMO; Detection; Sphere Decoder; Semidefinite Relaxation; Telecommunication; Telekommunikation;

    Abstract : The problem of detecting a vector of symbols, drawn from a finite alphabet and transmitted over a multiple-input multiple-output (MIMO) channel with Gaussian noise, is of central importance in digital communications and is encountered in several different applications. Examples include, but are not limited to; detection of symbols spatially multiplexed over a multiple-antenna channel and the multiuser detection problem in a code division multiple access (CDMA) system.

  6. 4. Computing Vector-valued Modular Forms of Congruence Types and of Some Extension Types

    Author : Tobias Magnusson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; eisenstein series; modular forms; iterated eichler-shimura integrals; vector-valued modular forms;

    Abstract : This thesis explores applications of vector-valued modular forms of congruence and extension types to scalar-valued modular forms for congruence subgroups with a character, higher order modular forms, and iterated Eichler-Shimura integrals of depth one and two, including considerable generalizations thereof. In \textsc{Paper I} (co-authored with Martin Raum), we present an algorithm for computing bases for spaces of vector-valued modular forms of congruence type and of weight at least $2$ in terms of products of components of vector-valued Eisenstein series.

  7. 5. Probing the early Universe with B-mode polarization : The Spider instrument, optical modelling and non-Gaussianity

    Author : Adriaan Judocus Duivenvoorden; Katherine Freese; Jón Emil Gudmundsson; Juan García-Bellido; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cosmic microwave background; early universe; polarimetry; telescopes; fysik; Physics;

    Abstract : One of the main goals of modern observational cosmology is to constrain or detect a stochastic background of primordial gravitational waves. The existence of such a background is a generic prediction of the inflationary paradigm: the leading explanation for the universe's initial perturbations. READ MORE
