Convergence of Array DBMS and Cellular Automata: A Road Traffic Simulation Case
P. 2399–2403.
Array DBMSs manage big N-d arrays, are not yet widely known, but are experiencing an R&D surge due to the rapid growth of array volumes. Cellular automata (CA) operate on a discrete lattice of cells that can be modeled by an N-d array. CA are successfully applied to model fire spread, land cover change, road traffic, and other processes. We made traffic CA simulations possible by array DBMS due to novel components: native UDF language, proactive exec plans, convolution operator, retiling strategy, array versioning, locks, virtual axes, etc. A database approach to CA brings powerful parallelization, data fusion, array processing, and interoperability to name a few. To our best knowledge, our work is the first to run end-to-end CA simulations completely inside array DBMS: we enable array DBMS to simulate the physical world for the first time.

Сверхпластическая газовая формовка – это один из способов обработки материалов давлением, используемый при производстве тонкостенных изделий сложной геометрической формы. Для проектирования технологических режимов производства таких изделий используется компьютерное моделирование технологического процесса, для которого необходимо задать свойства материала. Основной экспериментальный метод исследования свойств сверхпластичных материалов – одноосное растяжение плоских образцов с постоянной скоростью деформации. Однако, стандартная ...

T cell receptor (TCR) recognition of foreign peptides presented by major histocompatibility complex protein is a major event in triggering the adaptive immune response to pathogens or cancer. The prediction of TCR-peptide interactions has great importance for therapy of cancer as well as infectious and autoimmune diseases but remains a major challenge, particularly for novel ...

Array DBMSs operate on 𝑁-d arrays. During the Data Ingestion phase, the widely used mosaic operator ingests a massive collection of overlapping arrays into a single large array, called mosaic. The operator can utilize sophisticated statistical and machine learning techniques, e.g. Canonical Correlation Analysis (CCA), to produce a high quality seamless mosaic where the contrasts ...

Experiments based on multilevel computer simulations, which are becoming widespread today in scientific research practices, are forcing philosophers of science to shift the focus of attention from traditional concepts of scientific experiments to a fundamentally new methodology for designing, setting up and conducting an experiment. The computational power of modern high-performance clusters, which allow creating ...

Array DBMSs operate on big N-d arrays. Cellular automata (CA) work on a discrete lattice of cells, essentially on N-d arrays. CA facilitate decision support as they realistically simulate complex phenomena including road traffic, fire spread, and urban growth. Array DBMSs can bring numerous benefits to the CA domain via a ``database approach'': powerful parallelization, ...

We simulate the drop-chain movement in the two-dimensional channel using the lattice Boltzmann method coupled with the Immersed Boundary approach. We choose the asymmetric initial state of the drop chain to generate drop oscillations and calculate the wave spectrum. The numerical results coincide qualitatively with the experimental results obtained in the quasi-two-dimensional microfluidic device. ...

There is increasing interest in cumulative approaches to science, in which instead of
analyzing the results of individual papers separately, we integrate information
qualitatively or quantitatively. One such approach is meta-analysis, which has over 50
years of literature supporting its usefulness, and is becoming more common in
cognitive science. However, changes in technical possibilities by the widespread use of
Python ...

To date, it has been reliably shown that the lipid bilayer/water interface can be thoroughly characterized by a sophisticated so-called “dynamic molecular portrait”. The latter reflects a combination of time-dependent surface distributions of various physicochemical properties, inherent in both model lipid bilayers and natural multi-component cell membranes. One of the most important features of biomembranes ...

Array DBMSs strive to be the best systems for managing, processing, and even visualizing big N-d arrays. The last decade blossomed with R&D in array DBMS, making it a young and fast-evolving area. We present the first comprehensive tutorial on array DBMS R&D. We start from past impactful results that are still relevant today, then ...

In 2019, a new book by Lenhard was published. Lenhard attempts to separate computer simulations from classical mathematical modeling. Having structured the material accumulated over the years of research into three parts, Lenhard correctly, without starting the construction of revolutionary metaphysical concepts, takes the reader through the new world of the philosophy of computer simulations. ...
