  2. 1. Asthenopia in schoolchildren

    Author : Saber Abdi; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Asthenopia; prevalence; accommodative insufficiency; convergence; binocular disorders; refractive errors; Visual Analogue Scale; eye movements and reading;

    Abstract : Asthenopia is a term used to describe different symptoms associated with the use of the eyes, such as pain, blurred vision, diplopia, headaches. Asthenopia is most often reported in association with near vision. Children with asthenopia complain of such symptoms particularly when reading and writing. READ MORE

  4. 2. Transport of Particles in Turbulent Flow with Application to Bio-Fuels

    Author : Ammar Saber; Magnus Marklund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bio fuels; Turbulent flow; PIV measurement; Strömningslära; Fluid Mechanics;

    Abstract : Development of civilization faces a challenge of developing the resources of energy demand for the modern life. Extensive use of conventional fuel resources like crude oil and coal rise up a serious problem of increasing CO2 emission. New records levels of CO2 were registered during the early beginning of industrial revolution (http://climate.nasa. READ MORE

    Abstract : Establishing efficient methods for local administration of drugs to the inner ear has great clinical relevance for the management of inner ear disorders. However, the administration route remains a critical issue. READ MORE

  6. 4. Side-Channel Analysis of Post-Quantum Cryptographic Algorithms

    Author : Kalle Ngo; Johnny Öberg; Ingo Sander; Elena Dubrova; Lejla Batina; KTH; []
    Keywords : 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;

    Abstract : 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.

  7. 5. EMI from Switched Converters – Simulation Methods and Reduction Techniques

    Author : Andreas Henriksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; state space methods; EMI; semiconductor device modeling; diode reverse recovery; diode modeling; conducted emissions; Semiconductor device measurements; DC DC converters;

    Abstract : In this thesis, the conducted EMI from switched power converters has been analyzed using various existing models, own-derived models as well as measurements. The ingoing passive components in a switching converter have been modeled with respect to their high frequency behavior and the static and dynamic behavior of the active semiconductors has been analyzed.
