Universal Approach to Solution of Optimization Problems by Symbolic Regression
Applied Sciences, 2021 Optimization problems and their solution by symbolic regression methods are considered. The search is performed on non-Euclidean space. In such spaces it is impossible to determine a distance between two potential solutions and, therefore, algorithms ...

Arithmetic Coding for Data Compression [PDF]
Proceedings of the IEEE, 1994 Arithmetic coding provides an effective mechanism for removing redundancy in the encoding of data. We show how arithmetic coding works and describe an efficient implementation that uses table lookup as a first alternative to arithmetic operations. The reduced-precision arithmetic has a provably negligible effect on the amount of compression achieved ...

Компьютерная оптикаThe trend toward increasing the efficiency of computing systems and devices is directly related with the transition to parallel computing. We propose that parallel calculations should be conducted at the level of arithmetic operations using arithmetic ...

Language and Math: What If We Have Two Separate Naming Systems?
Languages, 2019 The role of language in numerical processing has traditionally been restricted to counting and exact arithmetic. Nevertheless, the impact that each of a bilinguals’ languages may have in core numerical representations has not been questioned until ...

Design and implementation of robust embedded processor for cryptographic applications [PDF]
, 2010 Practical implementations of cryptographic algorithms are vulnerable to side-channel analysis and fault attacks. Thus, some masking and fault detection algorithms must be incorporated into these implementations.

Secure FSM-based arithmetic codes [PDF]
Signal, Image and Video Processing, 2012 Recently, arithmetic coding has attracted the attention of many scholars because of its high compression capability. Accordingly, in this paper a method which adds secrecy to this well-known source code is proposed. Finite state arithmetic code (FSAC) is used as source code to add security.

Thermometer Code Based Modular Arithmetic [PDF]
2012 Spring Congress on Engineering and Technology, 2012 This paper presents a novel approach to perform modular arithmetic addition and subtraction using base-1 thermometer code data format for operands corresponding to the residues of the same modulus. Two n-bit thermometer code operands are first concatenated and logically shifted to produce a normalized 2n-bit thermometer code intermediate sum.

Membrane Wrapping for High Capacity and Rapidly Switchable Adhesives
Advanced Functional Materials, EarlyView.A membrane‐wrapping mechanism enables high‐capacity, rapidly switchable adhesion by coupling suction, friction, and adhesion. Broadband performance is achieved in dry and underwater conditions, allowing fast, reversible manipulation of objects of diverse sizes and shapes, from delicate eggs and berries to flat, complex, or heavy objects. These outcomes

Micromachines, 2019 Bose−Chaudhuri−Hocquenghem (BCH) codes are broadly used to correct errors in flash memory systems and digital communications. These codes are cyclic block codes and have their arithmetic fixed over the splitting field of their generator ...

Weight enumerators of Reed-Muller codes from cubic curves and their duals
, 2018 Let $\mathbb{F}_q$ be a finite field of characteristic not equal to $2$ or $3$. We compute the weight enumerators of some projective and affine Reed-Muller codes of order $3$ over $\mathbb{F}_q$.
