High-Speed Binary-to-Residue Converter Design Using 2-Bit Segmentation of the Input Word

open access: yesScientific Journal of Gdynia Maritime University, 2022
In this paper a new approach to the design of the high-speed binary-to-residue converter is proposed that allows the attaining of high pipelining rates by eliminating memories used in modulo m generators. The converter algorithm uses segmentation of the

Function argument number identification in stripped binary under PPC and MIPS instruction set

open access: yes网络与信息安全学报, 2020
The identification of the number of function argument contributes to the recovery of the function prototype and is the basis for data flow analysis and other security analysis.In order to improve the accuracy of the recognition of the number of function ...

Stability of Characteristics of Physical Random Number Generators

open access: yesDoklady Belorusskogo gosudarstvennogo universiteta informatiki i radioèlektroniki, 2023
The development of technologies leads to the need of revising the methods used to obtain cryptographic keys. The randomness parameters of sequences generated by physical random sequence generators are affected by the physical parameters of the recording ...

Generalised divisor sums of binary forms over number fields [PDF]

open access: yes, 2016
Estimating averages of Dirichlet convolutions $1 \ast \chi$, for some real Dirichlet character $\chi$ of fixed modulus, over the sparse set of values of binary forms defined over $\mathbb{Z}$ has been the focus of extensive investigations in recent years,

Antisquares and Critical Exponents [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2023
The (bitwise) complement $\overline{x}$ of a binary word $x$ is obtained by changing each $0$ in $x$ to $1$ and vice versa. An $\textit{antisquare}$ is a nonempty word of the form $x\, \overline{x}$.

Catalan fragile words [PDF]

open access: yesInternational Journal of Group Theory, 2020
‎Fragile words have been already considered in the context of automata groups‎. ‎Here we focus our attention on a special class of strongly fragile words that we call Catalan fragile words‎.

Alternative formulations to compute the binary shape Euler number

open access: yesIET Computer Vision, 2014
The authors propose two equations based on the pixel geometry and connectivity properties, which can be used to compute, efficiently, the Euler number of a binary digital image with either thick or thin boundaries.

Congruences for the Apéry numbers modulo p³ [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
Let {Aₙ'} be the Apéry numbers given by Aₙ'=\Σⁿₖ₌ₒ$binom{n}{k}$²$binom{n+k}{k}$. For any prime p≡3 (mod 4) we show that A'_{(p-1)/2}≡p²/3$binom{(p-3)/2}{(p-3)/4}$² (mod p³). Let {tₙ} be given by t₀=1, t₁=5 and tₙ₊₁=(8n²+12n+5)tₙ-4n²(2n+1)²tₙ₋₁ (n≥1).

Enumeration of Binary Trees and Universal Types [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
Binary unlabeled ordered trees (further called binary trees) were studied at least since Euler, who enumerated them. The number of such trees with n nodes is now known as the Catalan number.
