We aim to combine the semantics of spatial natural language specified as a linguistically motivated ontology, the Generalized Upper Model, with spatial logics or ontologies that specify space according to certain conceptualisations, based on regions, shapes, orientations, distances, or object properties. Such combinations, however, introduce uncertainties of various kinds, caused by different l...

RCC8 is a popular fragment of the region connection calculus, in which qualitative spatial relations between regions, such as adjacency, overlap and parthood, can be expressed. While RCC8 is essentially dimensionless, most current applications are confined to reasoning about two-dimensional or threedimensional physical space. In this paper, however, we are mainly interested in conceptual spaces...

An object of investigation is the differential geometry Riemannian Π-manifolds; in particular, a natural connection, determined by property its torsion tensor, defined, and it called second connection on Π-manifold. The uniqueness this proved, necessary sufficient condition for coincidence with known first considered manifolds found. form tensor obtained classes Π-manifolds, which differs from ...

The world is experiencing new relations and transformations between natural, synthetic, digital substances. Rather than considering these as materially distinct or ontologically separate, this Special Issue of TSANTSA interrogates how they are interlocked in socio-material processes mediation, transmutation, valuation. By conceptualizing the specificity their separateness, special issue makes p...

A natural connection with torsion is defined, and it called the first on Riemannian Π-manifold. Relations between introduced Levi–Civita are obtained. Additionally, relations their respective curvature tensors, Ricci scalar curvatures in main classes of a classification Π-manifolds presented. An explicit example dimension five provided.

A natural connection whose torsion tensor is a 3-form defined and called the third on Riemannian Π-manifold. In cases of existence this connection, relation between it known first second connections considered manifolds established. An explicit example dimension 5 given in confirmation proven assertions.

Purpose. Studying the tectonic features of structure earth’s crust Kryvyi Rih-Kremenchuk suture zone to clarify nature origin seismic events in Kryvbas. Methodology. To analyze and generalize data on Kryvbas seismicity with reference large-scale geological maps exploration work. study its based geological, geophysical studies drilling Rih superdeep well. Findings. In period 2011–2021, about 1,2...
