We improve iterative decoding of the moderate density parity-check codes, recently suggested as code candidates in the McEliece public key cryptosystem. In case of bit-flipping (BF) decoder failure, the code parity-check matrix is extended by adding auxiliary variable nodes based on reliability information from the BF decoder. Then iterative decoding is applied to the extended parity-check matrix.
Software startups use prototyping to develop and test business ideas and to validate market viability. While prototyping is emphasized in agile methods, there is little research on how startups can best utilise scarce resources to effectively use prototypes in their dynamic business context. We performed a case study of four startups and investigated how startups currently use prototyping to elici
Background. During the translation of mRNA into polypeptide, elongation factor G (EF-G) catalyzes the translocation of peptidyl-tRNA from the A site to the P site of the ribosome. According to the 'classical' model, EF-G in the GTP-bound form promotes translocation, while hydrolysis of the bound GTP promotes dissociation of the factor from the post-translocation ribosome. According to a more recen
We present a simple key-recovery attack on the LCMQ Authentication Protocol, an RFID authentication protocol proposed by Li, Gong, and Qin in 2013. We show that a successful attack is performed by solving a Learning Parity with Noise instance in a not-too-large dimension. For the proposed LCMQ parameters, the attack requires only a few invocations with the tag under attack. When there is no restri
We prove the first hardness results against efficient proof search by quantum algorithms. We show that under Learning with Errors (LWE), the standard lattice-based cryptographic assumption, no quantum algorithm can weakly automate TC0-Frege. This extends the line of results of Krajíček and Pudlák (Information and Computation, 1998), Bonet, Pitassi, and Raz (FOCS, 1997), and Bonet, Domingo, Gavaldà

In this paper, we propose a novel inter-domain fast-authentication scheme based on a concept of "trust clouds". A trust cloud is formed among neighbouring access points based on a relationship among the owners of the access points. Fast-authentication for inter-domain sites is achieved through cooperation among the trust cloud members. The approach is distributed without a central authentication s
Inom identitetsforskning finns det olika definitioner av identitet. För att få en djupare förståelse för begreppet identitet, har jag valt att undersöka hur kosovoalbaner förhåller sig till sin identitet i ett svenskt samhälle. De empiriska uppgifterna samlades in genom kvalitativa semi-strukturerade intervjuer. Min analys baserades på begreppen identitet, tillhörighet och kultur. Baserat på det e
Rapid Clay Formations (RCF) is an ongoing research project investigating robotic aggregation of soft clay elements. This thesis presents our research into RCF construction on an architectural scale. It outlines our development of a fabrication process suitable for the construction of tall and slender structures made out of clay. This fabrication process is evaluated through a series of prototypes
Arbetet med att identifiera och inventera förorenade områden är en del av Sveriges miljökvalitetsmål. Regeringen har fastställt 16 mål, och ett av dessa är Giftfri miljö. För att våra kommande generationer ska få leva i en miljö fri från föroreningar behöver vi städa upp efter nuvarande och tidigare farliga utsläpp. Landets länsstyrelser har fått i uppdrag av Regeringen att genomföra identifieringThe process of identifying and inventorying polluted areas is part of The Environmental Objectives in Sweden. The government has put down 16 objectives, and one of these is A Non-Toxic Environment. To ensure that our future generations will live in an environment free from pollution, we need to clean up after current and former hazardous emissions. All of Sweden’s Länsstyrelser have been commissio

Free-electron lasers will change the way we carry out time-resolved X-ray experiments. At present date, we use laser-produced plasma sources or synchrotron radiation. Laser-produced plasma sources have short pulses, but unfortunately large pulse-to-pulse fluctuations and large divergence. Synchrotron radiation from third generation source provide collimated and stable beams, but unfortunately long
Purpose: The purpose of this thesis is to examine the role of online store image in the internationalization process of online retailers. Based on the assumption that a favorable image is a competitive advantage for retailers, this master thesis examines whether or not a favorable domestic online store image, can be replicated in the in- ternationalization process of online retailers. Using a comp
In blood, the oxygen-transporting protein hemoglobin (Hb) governs the oxygenation of cells and tissues. Naturally, this protein has claimed a place in the center of the research field of artificial oxygen therapeutics. Such Hb-based products have used cell-free Hb purified from human, bovine, invertebrate, or recombinant sources to create hemoglobin-based oxygen carriers (HBOCs). However, administ
