  1. 16. Some Notes on Post-Quantum Cryptanalysis

    Författare :Erik Mårtensson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cryptography; Post-quantum cryptography; LWE; BKW; Cryptanalysis; Lattice sieving; SVP; Lattice-based cryptography; Code-based cryptography;

    Sammanfattning : Cryptography as it is used today relies on a foundational level on the assumptionthat either the Integer Factoring Problem (IFP) or the DiscreteLogarithm Problem (DLP) is computationally intractable. In the 1990s PeterShor developed a quantum algorithm that solves both problems in polynomialtime. LÄS MER

  3. 17. Ultrasound Doppler Based In-Line Rheometry - Development, Validation and Application

    Författare :Johan Wiklund; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Food and drink technology; Livsmedelsteknik; Technological sciences; non-Newtonian; Chemistry; Kemi; process control; In-line rheometry; Doppler; process monitoring; ultrasound;

    Sammanfattning : The trend within fluid industry is towards continuous production, leading to an increasing demand for new and improved methods that allow real-time monitoring of quality parameters and fast process control. The consistency and viscosity can be described by fluid rheology and are frequently used as quality control parameters. LÄS MER

  4. 18. Performance Analysis of Application-Specific Multicore Systems on Chip

    Författare :Iyad Al Khatib; Axel Jantsch; Jari Nurmi; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multicore; System on Chip; Performance; Information technology; Informationsteknik;

    Sammanfattning : The last two decades have witnessed the birth of revolutionary technologies in data communications including wireless technologies, System on Chip (SoC), Multi Processor SoC (MPSoC), Network on Chip (NoC), and more. At the same time we have witnessed that performance does not always keep pace with expectations in many services like multimediaservices and biomedical applications. LÄS MER
