Stone Enclosures —Linking Time and Guiding Space

open access: yesCurrent Swedish Archaeology, 1996
From the late Roman Iron Age, stone enclosures and houses with a stone foundation have been built on Gotland. Stone enclosures have generally been interpreted as fences between the infields and the outlying land.

Disconnection in the Alexandroff duplicate

open access: yesApplied General Topology, 2021
It was demonstrated in [2] that the Alexandroff duplicate of the Čech-Stone compactification of the naturals is not extremally disconnected. The question was raised as to whether the Alexandroff duplicate of a non-discrete extremally disconnected space ...

Damping of dynamic forces by materials used in the construction of ballast and ballastless railway tracks. Crushed stone

open access: yesВестник Научно-исследовательского института железнодорожного транспорта, 2019
Strength properties of mineral materials used in the track operation, which are crushed stone and sand, do not depend on the ambient temperature (up to 500 °C) and humidity, but gradually degrade when its pore space becomes clogged with fines, oil ...

Implicit Semantic Role of Material on the Quality of Living Space Using Semantic Differential Technique

open access: yesSAGE Open, 2022
Living spaces have been recognized as one of the functional spaces of housing. Materials and textures are regarded as some of the features of the space.

A Stone-Cech Compactification for Limit Spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1970
Wyler (Notices Amer. Math. Soc. 15 (1968), 169. Abstract #653-306.) has given a Stone-tech compactification for limit spaces. However, his is not necessarily an embedding. Here, it is shown that any Hausdorff limit space (X, r) can be embedded as a dense subspace of a compact, Hausdorff, limit space (X1, ri) with the following property: any continuous ...

A description of the Stone space of Banach lattice C(K,E)

open access: yesJournal of Function Spaces and Applications, 2006
We give a topological description of the Stone space of C(K,E), Banach lattices of continuous functions from a compact Hausdorff space K into a Banach lattice E.

STONE IN AN URBAN SPACE – ITS POTENTIAL TO PROMOTE GEOTOURISM [PDF]

open access: yesGeo Journal of Tourism and Geosites, 2019
The geological heritage of Pruszków, although with an easy access, remains beyond the knowledge and consciousness of its inhabitants. Besides the short description of the area’s geodiversity, the article presents ten large erratic boulders and other ...

Stone spaces and compactifications

open access: yesPure Mathematical Sciences, 2013
This paper deal with spaces such that their compactification is a Stone space. The particular cases of the one-point compactification, the Wallman compactification and the Stone- ˇ Cech compactification are studied.

Framework for Mapping Sublimation Features on Mars’ South Polar Cap Using Object-Based Image Analysis

open access: yesRemote Sensing
Mars’ south polar cap hosts dynamic landforms known as Swiss cheese features (SCFs), which form through the sublimation of carbon dioxide (CO2) ice driven by the planet’s extreme seasonal and diurnal solar insolation cycles.
