  1. 1. Chemoenzymatic synthesis of anionic alkyl glycosides

    Författare :NGOC NGO; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alkyl glycosides; laccase; TEMPO; oxidation; cyclodextrin glucanotransferases;

    Sammanfattning : Growing concerns for environmental issues and product safety for users have shifted research interests towards the use of renewable resources and climate-neutral processes. The enzymatic approach having high selectivity under mild reaction conditions is promising, and the nature-originating products are well accepted. LÄS MER

  3. 2. Side-Channel Analysis of Post-Quantum Cryptographic Algorithms

    Författare :Kalle Ngo; Johnny Öberg; Ingo Sander; Elena Dubrova; Lejla Batina; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Side-channel attack; Post-quantum cryptography; Deep learning; LWE LWR-based KEM; Hardware security; Sidokanalsattack; Postkvantkryptering; Djupinlärning; LWE LWR-baserad KEM; Hårdvarusäkerhet; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Public key cryptographic schemes used today rely on the intractability of certain mathematical problems that are known to be efficiently solvable with a large-scale quantum computer. To address the need for long-term security, in 2016 NIST started a project for standardizing post-quantum cryptography (PQC) primitives that rely on problems not known to be targets for a quantum computer, such as lattice problems.

  4. 3. Massive MIMO: Fundamentals and System Designs

    Författare :Hien Quoc Ngo; Erik G. Larsson; Giuseppe Caire; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The last ten years have seen a massive growth in the number of connected wireless devices. Billions of devices are connected and managed by wireless networks. At the same time, each device needs a high throughput to support applications such as voice, real-time video, movies, and games. LÄS MER

  5. 4. Model Checking of Software Systems under Weak Memory Models

    Författare :Tuan-Phong Ngo; Mohamed Faouzi Atig; Parosh Aziz Abdulla; Philipp Rümmer; Viktor Vafeiadis; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model checking; Concurrent program; Weak memory model; Computer Science; Datavetenskap;

    Sammanfattning : When a program is compiled and run on a modern architecture, different optimizations may be applied to gain in efficiency. In particular, the access operations (e.g., read and write) to the shared memory may be performed in an out-of-order manner, i. LÄS MER

  7. 5. Utilisation of health services in a transitional society : studies in Vietnam 1991-1999

    Författare :Ngo Van Toan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Utilisation; expenditure; exemption; reproductive health; outpatient services; transition; Vietnam.;

    Sammanfattning : General objective: The general objective is to assess the utilisation of public health services among different social groups in a period of rapid policy and society changes in Vietnam. Methods: Studies on the utilisation of reproductive health services were based on one household survey conducted in a lowland district in 1992 and two other surveys performed in 1991 and 1994 in a highland district.
