In this note, we deduce a bound between fast algebraic immunity and higher order nonlinearity (it is the first time that a bound between these two cryptographic criteria is given), and find that a Boolean function should have high r-order nonlinearity to resist fast algebraic attacks. As a corollary, we find that no matter how much effort we make, the Tu-Deng functions cannot be repaired in a stan
Popular Abstract in Swedish Vi använder allt mer energi och efterfrågan kommer bara öka, fram till 2050 spås en fördubbling av världens efterfrågan av energi. Drygt 85 procent av den energi som produceras i dag kommer från fossila bränslen som bidrar till växthuseffekten. En ny rapport från FN:s klimatpanel, IPCC, visar att koldioxid står för runt 76 procent av det totala utsläppet av växthusgasAccelerating actions to mitigate CO2 emissions was one of the important messages at the UN Climate Summit 2014. About 85 % of the world’s energy is provided through the burning of fossil fuels, which is the main source of CO2 emissions. Increasing the share of renewable energy, and making energy efficiency improvements and savings were actions that were agreed upon to meet CO2 emission reductions.
Certec has been working with touch-based interfaces - haptic interfaces - since 1995, exploring the possibilities they can offer people with different kinds of disabilities. A haptic interface transmits forces to your hand or fingers in a way that mimics
This thesis contains two main aspects of my research work towards physics in proton-proton collisions in the ATLAS experiment at the LHC. First, a Monte Carlo based analysis of the event yield and the mass shape for the ground state of the B_c meson in the hadronic decay channel B_c -> J/psi + pi was studied. The selection criteria have been optimised, the total number of signal events, and the si
What is woman’s role in the modernist avant-garde? Feminist art historians have long criticised the dominant masculinity of modernism. The problem, as I see it, is the unreflecting way in which history is written, and the way in which women are squeezed into theoretic models that really only affirm, and cater primarily for, men. The German-Swiss artist Meret Oppenheim (1913-1985) has been describe
