On Some Model Theoretic Properties of Totally Bounded Ultrametric Spaces

open access: yesMathematics, 2022
Continuing investigations initiated by the first author, we associate relational structures for metric spaces and investigate their model theoretic properties. In this paper, we consider ultrametric spaces.

An Improved Acoustic Diffusion Equation Model for Long-Channel Underground Spaces

open access: yesSensors, 2023
The acoustic diffusion equation model has been widely applied in various scenarios, but a larger prediction error exists when applied to underground spaces, showing a significantly lower characteristic of the sound pressure level in the later stage ...

Generalizations of Snyder model to curved spaces

open access: yesPhysics Letters B, 2022
We consider generalizations of the Snyder algebra to a curved spacetime background with de Sitter symmetry. As special cases, we obtain the algebras of the Yang model and of triply special relativity.

“In Space” or “As Space”?: A New Model [PDF]

open access: yesLife, 2012
In this analysis natural systems are posed to subsystemize in a manner facilitating both structured information/energy sharing and an entropy maximization process projecting a three-dimensional, spatial, outcome. Numerical simulations were first carried out to determine whether n × n input-output matrices could, once entropy-maximized, project a three ...

Theater, Space and Place Making in North-East Bangladesh

open access: yesProceedings of the International Conference of Contemporary Affairs in Architecture and Urbanism-ICCAUA, 2022
Although Theater activities inject a significant effect on outdoor public affairs, local urban planners do not sufficiently consider such impact while designing a new civic theater in Habiganj, a growing sub-urban district of Bangladesh.

Model Checking Spatial Logics for Closure Spaces [PDF]

open access: yesLogical Methods in Computer Science, 2017
Spatial aspects of computation are becoming increasingly relevant in Computer Science, especially in the field of collective adaptive systems and when dealing with systems distributed in physical space. Traditional formal verification techniques are well

The Tao of Modeling Spaces. [PDF]

open access: yesThe Journal of Object Technology, 2006
The paper introduces modeling spaces in order to help software practitioner to understand modeling. Usually software engineers often think of a specific kind of models – UML models, but there are many open questions such as: Should we assume that the code we write is a model or not; What are models and metamodels, and why do we need them; What does it ...
