  1. 1. Reconciling gene family evolution and species evolution

    Författare :Joel Sjöstrand; Jens Lagergren; Nicolas Lartillot; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computational biology; Bioinformatics; Phylogenetics; Phylogenomics; Comparative genomics; Evolutionary biology; datalogi; Computer Science;

    Sammanfattning : Species evolution can often be adequately described with a phylogenetic tree. Interestingly, this is the case also for the evolution of homologous genes; a gene in an ancestral species may – through gene duplication, gene loss, lateral gene transfer (LGT), and speciation events – give rise to a gene family distributed across contemporaneous species.

  3. 2. Timing and Schedulability Analysis of Real-Time Systems using Hidden Markov Models

    Författare :Anna Friebe; Thomas Nolte; Alessandro Papadopoulos; Filip Markovic; Liliana Cucu-Grosjean; Mälardalens universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Sammanfattning : In real-time systems functional requirements are coupled to timing requirements, a specified event needs to occur at the appropriate time.  In order to ensure that timing requirements are fulfilled, there are two main approaches, static and measurement-based. LÄS MER

  4. 3. Determination of Banned Azo Dyes in Leather

    Författare :Lars-Henric Ahlström; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; Analytical chemistry; extraction; azo dyes; aromatic amines;

    Sammanfattning : Dyes are commercially indispensable and the expanding industry offers a complete palette of colors. Azo dyes constitute the largest chemical class of synthetic dyes because of their versatility, low price, and ease of production. LÄS MER

  5. 4. Modeling and optimization of least-cost corridors

    Författare :Lindsi Seegmiller; Takeshi Shirabe; Kai-Florian Richter; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; raster data modeling; raster-based geographic information systems; route planning; optimal routing; corridor; wide path; corridor width; distortion; three-dimensional grid; rasterdatamodellering; rasterbaserade geografiska informationssystem; ruttplanering; optimal dirigering; korridor; bred väg; korridorbredd; distorsion; tredimensionellt rutnät; Geoinformatics; Geoinformatik;

    Sammanfattning : Given a grid of cells, each having a value indicating its cost per unit area, a variant of the least-cost path problem is to find a corridor of a specified width connecting two termini such that its cost-weighted area is minimized. A computationally efficient method exists for finding such corridors, but as is the case with conventional raster-based least-cost paths, their incremental orientations are limited to a fixed number of (typically eight orthogonal and diagonal) directions, and therefore, regardless of the grid resolution, they tend to deviate from those conceivable on the Euclidean plane.

  7. 5. On the Treatment of Flow in Traffic Safety Analysis, - a non-parametric approach applied on vulnerable road users

    Författare :Lars Ekman; Trafik och väg; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Social sciences; Samhällsvetenskaper; Teknik; Technological sciences; safety performance function; accuracy; simulation; bootstrap; bicyclist; pedestrian; risk; Traffic Safety; accident rate;

    Sammanfattning : The treatment of flow in the area of traffic safety has a long tradition. The influence flow has on the number of accidents is, however, often considered so obvious that it tends to be trivial. In this thesis I can show that the relation between flow and accidents holds interesting information. LÄS MER
