  1. 16. Model-based System Testing of Safety-Critical Embedded Software

    Författare :Muhammad Nouman Zafar; Wasif Afzal; Eduard Paul Enoiu; Cyrille Artho; Mälardalens universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : System-level testing of safety-critical embedded systems is complex and costly. MBT has shown promising results in terms of fault detection effectiveness and efficiency of test generation and execution. However, the industrial adoption of MBT approaches is slow and limited to specific industries and domains. LÄS MER

  3. 17. Spatially Adaptive Analysis and Segmentation of Polarimetric SAR Data

    Författare :Wei Wang; Yifang Ban; Jianwei Wan; Xiaoxiang Zhu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polarimetric SAR; Spatially adaptive; Edge detection; Spherically invariant random vector SIRV ; Superpixel; Simple linear iterative clustering SLIC ; Entropy rate; Segmentation;

    Sammanfattning : In recent years, Polarimetric Synthetic Aperture Radar (PolSAR) has been one of the most important instruments for earth observation, and is increasingly used in various remote sensing applications. Statistical modelling and scattering analysis are two main ways for PolSAR data interpretation, and have been intensively investigated in the past two decades. LÄS MER

  4. 18. Mutations and Mutation Rate in the Development of Fluoroquinolone Resistance

    Författare :Patricia Komp Lindgren; Diarmaid Hughes; Fernando Baquero; Uppsala universitet; []
    Nyckelord :Microbiology; Mutation rate; Fluoroquinolone; Resistance; Biological fitness; Urinary tract infection; Escherichia coli; MPC; Mikrobiologi;

    Sammanfattning : The emergence of multidrug resistant bacteria world wide is a serious problem, and very few new drugs are under development. The selection of resistant bacteria is affected by factors such as mutation rate, biological fitness cost and the rate of fitness compensation. LÄS MER

  5. 19. Ultra-wideband Millimeter-wave Antenna Arrays and Front-end Systems : For high data rate 5G and high energy physics applications

    Författare :Imran Aziz; Dragos Dancila; Ville Viikari; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The demand for wireless data communications is rapidly increasing due to several factors including increased internet access, increasingly growing number of mobile users and services, implementation of the Internet of Things (IoT), high-definition (HD) video streaming and video calling. To meet the bandwidth requirement of new and emerging applications, it is necessary to move from the existing microwave bands towards millimeter-wave bands. LÄS MER
