A Secure Multiple Elliptic Curves Digital Signature Algorithm for Blockchain [PDF]
arXiv, 2018 Most cryptocurrency systems or systems based on blockchain technology are currently using the elliptic curves digital signature algorithm (ECDSA) on the secp256k1 curve, which is susceptible to backdoors implemented by the curve creator (secp256k1). The paper proposes a multiple elliptic curves digi-tal signature algorithm (MECDSA), which allows not ...

On the Small Ball Inequality in All Dimensions [PDF]
arXiv, 2007 Let h_R denote an L ^{\infty} normalized Haar function adapted to a dyadic rectangle R contained in the unit cube in dimension d. We establish a non-trivial lower bound on the L^{\infty} norm of the `hyperbolic' sums $$ \sum _{|R|=2 ^{-n}} \alpha(R) h_R (x) $$ The lower bound is non-trivial in that we improve the average case bound by n^{\eta} for some

Action Recognition in Video Using Sparse Coding and Relative Features [PDF]
arXiv, 2016 This work presents an approach to category-based action recognition in video using sparse coding techniques. The proposed approach includes two main contributions: i) A new method to handle intra-class variations by decomposing each video into a reduced set of representative atomic action acts or key-sequences, and ii) A new video descriptor, ITRA ...

Om å kartleggja mørk materie med maskinlæring [PDF]
NIK, 1 (2023)Gravitational lensing occurs as the path of light from distant celestial bodies is distorted due to gravitational attraction by other celestial bodies, whose mass is partly invisible, being so-called dark matter. When observed through a gravitational lens, distant galaxies appear distorted.

The Impact of Foreign Players in the English Premier League: A Mathematical Analys [PDF]
arXivWe undertake extensive analysis of English Premier League data over the period 2009/10 to 2017/18 to identify and rank key factors affecting the economic and footballing performances of the teams. Alternative end-of-season league tables are generated by re-ranking the teams based on five different descriptors - total expenditure, total funds spent on ...
