Classification of Multioperations of Rank 2 by E-precomplete Sets

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2020
In this paper multioperations defined on a two-element set and their closure operator based on composition operator and the equality predicate branching operator is considered. The composition operator is based on union of sets.

Fast Line Segment Detection and Large Scene Airport Detection for PolSAR

open access: yesRemote Sensing, 2022
In this paper, we propose a fast Line Segment Detection algorithm for Polarimetric synthetic aperture radar (PolSAR) data (PLSD). We introduce the Constant False Alarm Rate (CFAR) edge detector to obtain the gradient map of the PolSAR image, which tests ...

FO2(<,+1,~) on data trees, data tree automata and branching vector addition systems [PDF]

open access: yesLogical Methods in Computer Science, 2016
A data tree is an unranked ordered tree where each node carries a label from a finite alphabet and a datum from some infinite domain. We consider the two variable first order logic FO2(

Efficient Multi-Client Functional Encryption for Conjunctive Equality and Range Queries

open access: yesIEEE Access, 2022
In multi-client functional encryption (MC-FE) for predicate queries, clients generate ciphertexts of plaintexts $x_{1}, \ldots, x_{n}$ binding with a time period $T$ and store them on a cloud server, and the cloud server receives a function key ...

Multi-client Predicate-Only Encryption for Conjunctive Equality Tests [PDF]

open access: yes, 2018
We propose the first multi-client predicate-only encryption scheme capable of efficiently testing the equality of two encrypted vectors. Our construction can be used for the privacy-preserving monitoring of relations among multiple clients. Since both the clients’ data and the predicates are encrypted, our system is suitable for situations in which ...

The Completeness Criterion for Closure Operator with the Equality Predicate Branching on the Set of Multioperations on Two-Element Set

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2019
Multioperations are operations from a finite set A to set of all subsets of A. The usual composition operator leads to a continuum of closed sets. Therefore, the research of closure operators, which contain composition and other operations becomes ...

On the Decidability of Connectedness Constraints in 2D and 3D Euclidean Spaces [PDF]

open access: yes, 2011
We investigate (quantifier-free) spatial constraint languages with equality, contact and connectedness predicates as well as Boolean operations on regions, interpreted over low-dimensional Euclidean spaces. We show that the complexity of reasoning varies

Mathematical foundations of epistemology based on experiments

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2015
The paper deals with basic prerequisites for the development of epistemology, which uses information concerning real experiments in the real world (with real objects).

A Bounded Domain Property for an Expressive Fragment of First-Order Linear Temporal Logic [PDF]

open access: yes, 2019
First-Order Linear Temporal Logic (FOLTL) is well-suited to specify infinite-state systems. However, FOLTL satisfiability is not even semi-decidable, thus preventing automated verification. To address this, a possible track is to constrain specifications

A Fine-Grained Hierarchy of Hard Problems in the Separated Fragment [PDF]

open access: yes, 2017
Recently, the separated fragment (SF) has been introduced and proved to be decidable. Its defining principle is that universally and existentially quantified variables may not occur together in atoms.
