QIACO: A Quantum Dynamic Cost Ant System for Query Optimization in Distributed Database

open access: yesIEEE Access, 2021
Query optimization is considered as the most significant part in a model of distributed database. The optimizer tries to find an optimal join order, which reduces the query execution cost. Several factors may affect the cost of query execution, including

Moments in Pickwick: Opening a window into women’s lived experiences of transitional housing through participatory filmmaking

open access: yesScreenworks, 2022
This film utilises participatory filmmaking to explore transitional housing in Pickwick, Cape Town. As we join five women inhabiting the space, we gain insights into their lived experience of the environment.

Projection Based Large Scale High-Dimensional Data Similarity Join Using MapReduce Framework

open access: yesIEEE Access, 2020
Similarity join has been widely used in many data analysis and data mining applications, we mainly focus on the scalability and performance problem of similarity join query on massive high-dimensional data set.

Representations of bornologies

open access: yesApplied General Topology, 2022
Bornologies abstract the properties of bounded sets of a metric space. But there are unbounded bornologies on a metric space like $\mathcal{P}(\RR)$ with the Euclidean metric.

Algebraic Spaces and Set Decompositions

open access: yesRatio Mathematica, 2018
The contribution is growing up from certain parts of scientific work by professor Boruvka in several ways. Main focus is on the decomposition theory, especially algebraized decompositions of groups.

Modeling of complete combustion reaction of room temperature gaseous Alkanes via join space

open access: yesBulletin of Computational Applied Mathematics, 2021
Alkanes are highly flammable compound at high temperatures. Complete combustion of gaseous alkanes in presence of sufficient oxygen results in the production of steam (H2O(g)), and carbon dioxide (CO2(g)). The reaction is exothermic.

From lattices to Hv-matrices

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016
In this paper we study the concept of sets of elements, related to results of an associative binary operation. We discuss this issue in the context of matrices and lattices.

Exploiting database similarity joins for metric spaces [PDF]

open access: yesProceedings of the VLDB Endowment, 2012
Similarity Joins are recognized among the most useful data processing and analysis operations and are extensively used in multiple application domains. They retrieve all data pairs whose distances are smaller than a predefined threshold ε. Multiple Similarity Join algorithms and implementation techniques have been proposed. They range from

Abelization of join spaces of affine transformations of ordered field with proximity

open access: yesApplied General Topology, 2005
Using groups of affine transformations of linearly ordered fields a certain construction of non-commutative join hypergroups is presented based on the criterion of reproducibility of semi-hypergroups which are determined by ordered semigroups. The aim of

Space Weather in the Popular Media, and the Opportunities the Upcoming Solar Maximum Brings

open access: yesSpace Weather, 2023
The media interest/coverage of space weather has been increasing as we approach solar maximum and the private space industry has grown significantly since the last significant solar maximum in 2000–2002.
