α-Scattered spaces [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1998
α-scattered spaces, spaces whose α-topology is scattered, are introduced and used to slightly extend a recent result of A. V. Arhangel'skii and P. J. Collins [1]. Strong irresolvability of J. Foran and P.

On Scattered Spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1974
We show that each 0 0 -dimensional Hausdorff space which is scattered can be mapped continuously in a one-to-one way onto a scattered 0 0 -dimensional Hausdorff space of the same weight as its cardinality. This gives an easier and a new proof of the fact that a countable regular space admits a coarser compact Hausdorff

Function Replacement Decision-Making for Parking Space Renewal Based on Association Rules Mining

open access: yesLand, 2022
Parking lots are typical urban spaces with a large total area and scattered distribution. With the development of smart cars and shared driving, parking demand is likely to decline.

Supporting Bees in Cities: How Bees Are Influenced by Local and Landscape Features

open access: yesInsects, 2021
Urbanization is a major anthropogenic driver of decline for ecologically and economically important taxa including bees. Despite their generally negative impact on pollinators, cities can display a surprising degree of biodiversity compared to other ...

Microwave Tomography With LSTM-Based Processing of the Scattered Field

open access: yesIEEE Open Journal of Antennas and Propagation, 2021
The quantitative inspection of unknown targets or bodies by means of microwave tomography requires a proper modeling of the field scattered by the structures under test, which in turn depends on several factors related to the adopted antennas and ...

ParacompactC-scattered spaces [PDF]

open access: yesPacific Journal of Mathematics, 1987
A Hausdorff topological space X is said to be C-scattered [\textit{R. Telgársky}, Fundam. Math. 73, 59-74 (1971; Zbl 0226.54018)] provided that each of its non-empty closed subspaces contains a compact set with a non-empty relative interior. The authors prove that each countable product of paracompact C-scattered spaces is paracompact. A corollary says

Public green space quantity and distribution in Cairo, Egypt

open access: yesJournal of Engineering and Applied Science, 2022
Green spaces are recognised as an important contributor in enhancing the quality of urban life. Many cities are now working on preserving and increasing their green spaces as a part of their sustainable development plans.

Geometric scattering on measure spaces

open access: yesApplied and Computational Harmonic Analysis, 2022
The scattering transform is a multilayered, wavelet-based transform initially introduced as a model of convolutional neural networks (CNNs) that has played a foundational role in our understanding of these networks' stability and invariance properties.

Momentum-space Scattering Extremizations

open access: yesLaser & Photonics Reviews, 2023
Studies into scatterings of photonic structures have been so far overwhelmingly focused on their dependencies on the spatial and spectral morphologies of the incident waves. In contrast, the evolution of scattering properties through another parameter space of incident directions (momentum space) has attracted comparably little attention, though of ...

Impact of urban densification on building energy consumption [PDF]

open access: yesE3S Web of Conferences, 2020
The close layout of buildings is an important cause of urban densification. It makes solar radiation and long-wave radiation being blocked, scattered, and reflected multiple times. Radiant heat is a key factor affecting building energy consumption.
