Implementation and improvements of affine arithmetic

open access: yesNonlinear Theory and Its Applications, IEICE, 2015
Affine arithmetic is a well-known tool to reduce the wrapping effect of ordinary interval arithmetic. We discuss several improvements both in theory and in terms of practical implementation. In particular details of INTLAB's affine arithmetic toolbox are presented. Computational examples demonstrate advantages and weaknesses of the approach.

Dispatching optimization of city gas station district energy systems with multiple uncertainties based on an improved affine arithmetic method

open access: yesEnergy Reports, 2023
According to the energy consumption characteristics of gas stations, the district energy system (DES) based on natural gas and renewable energy is a suitable form of energy supply.

Interval power flow calculation algorithm for multi‐terminal dc distribution networks considering distributed generation output uncertainties

open access: yesIET Generation, Transmission & Distribution, 2021
An interval power flow calculation (PFC) algorithm for multi‐terminal DC distribution networks is proposed to handle the uncertainties of distributed generation output powers and loads.

FDFB: Full Domain Functional Bootstrapping Towards Practical Fully Homomorphic Encryption

open access: yesTransactions on Cryptographic Hardware and Embedded Systems, 2022
Computation on ciphertexts of all known fully homomorphic encryption (FHE) schemes induces some noise, which, if too large, will destroy the plaintext.

Fit the Joint Moments: How to Attack Any Masking Scheme

open access: yesIEEE Access, 2022
Side-Channel Analysis (SCA) allows extracting secret keys manipulated by cryptographic primitives through leakages of their physical implementations. Supervised attacks, known to be optimal, can theoretically defeat any countermeasure, including masking,

Evaluation of Electric Vehicles Hosting Capacity Based on Interval Undervoltage Probability in a Distribution Network

open access: yesIEEE Access, 2021
The rapidly growing market for electric vehicles (EVs) and chargers has a considerable influence on the operation of the distribution network. Accurate evaluation of the number of EVs penetrating the distribution network, that is, the hosting capacity ...

Semënov Arithmetic, Affine VASS, and String Constraints

open access: yes, 2023
We study extensions of Semënov arithmetic, the first-order theory of the structure $(\mathbb{N}, +, 2^x)$. It is well-knonw that this theory becomes undecidable when extended with regular predicates over tuples of number strings, such as the Büchi $V_2$-predicate.

Ray casting implicit fractal surfaces with reduced affine arithmetic [PDF]

open access: yes, 2007
A method is presented for ray casting implicit surfaces defined by fractal combinations of procedural noise functions. The method is robust and uses affine arithmetic to bound the variation of the implicit function along a ray.

Modified Affine Arithmetic Is More Accurate than Centered Interval Arithmetic or Affine Arithmetic [PDF]

open access: yes, 2003
In this paper we give mathematical proofs of two new results relevant to evaluating algebraic functions over a box-shaped region: (i) using interval arithmetic in centered form is always more accurate than standard affine arithmetic, and (ii) modified affine arithmetic is always more accurate than interval arithmetic in centered form. Test results show

On the distribution of orbits in affine varieties [PDF]

open access: yes, 2014
Given an affine variety $X$, a morphism $\phi:X\to X$, a point $\alpha\in X$, and a Zariski closed subset $V$ of $X$, we show that the forward $\phi$-orbit of $\alpha$ meets $V$ in at most finitely many infinite arithmetic progressions, and the remaining
