Convergence of space and time through GIS [PDF]
Glasnik Srpskog Geografskog Društva, 2023 Human's exploration of space has changed over time, depending on the expansion of the limits of his knowledge. Space is infinite, but it is limited by the possibility of human knowledge. The original man knew very little about the space in which

Compactifications of convergens spaces
International Journal of Mathematics and Mathematical Sciences, 1979 This paper summarizes most of the results to date on convergence space compactifications, and establishes necessary and sufficient conditions for the existence of largest and smallest compactifications subject to various conditions imposed upon the ...

Tuning Multiple Fano Resonances for On-Chip Sensors in a Plasmonic System
Sensors, 2019 This paper proposed a plasmonic resonator system, consisting of a metal-insulator-metal structure and two stubs, and a Fano resonance arose in its transmittance, which resulted from the coupling between the two stubs.

Separation axioms for partially ordered convergence spaces
International Journal of Mathematics and Mathematical Sciences, 1984 In partially ordered convergence spaces, separation axioms are introduced and then related to the concept of complete separatedness due to Nachbin as well as to connectedness concepts. A method to generate new separation axioms is studied.

Multi-core fiber channel equalization algorithm based on K nearest neighbor method [PDF]
ITM Web of Conferences, 2022 Aiming at the channel damage problems of multi-core fiber (Multi-core Fiber, MCF), the AKNN (Adapted K-Nearest Neighbor) algorithm is proposed. The MATLAB software was used to simulate the channel of the seven-core fiber, both the inter-core crosstalk ...

Compactifying a convergence space with functions
International Journal of Mathematics and Mathematical Sciences, 1996 A convergence space is a set together with a convergence structure. In this paper we discuss a method of constructing compactifications on a class of convergence spaces by use of functions.

A class of completely regular spaces
International Journal of Mathematics and Mathematical Sciences, 1984 In this paper we investigate topologies with ultrafilters having bases of open sets. It is shown that these topologies are completely regular. All results are obtained by using Richardson's compactification of convergence spaces.

Performance Analysis and Power Tilt Mitigation of Ultra-Wideband WDM Transmission Systems
Photonics, 2023 Ultra-wideband (UWB) wavelength division multiplexing (WDM) transmission, which utilizes low-loss spectral windows of single-mode fiber for data transmission, is a highly promising method for increasing the capacity of optical communication.

Generalized Statistical Convergence and Convergence Free Spaces
Journal of Mathematical Analysis and Applications, 2000 The statistical convergence was introduced by H. Fast in 1951. Since then this notion has been studied by many authors including J. Connor, J. A. Fridy, H. I. Miller, A. R. Freedman, J. J. Sember, I. J. Maddox, T. Salat, etc. In this paper, by using the concepts of convergence free spaces, cofilters and filters based on a countably infinite set, the ...

I-Statistical convergence in 2-normed space
Arab Journal of Mathematical Sciences, 2014 In this paper, we investigate the notion I-statistical convergence and I-statistical Cauchy sequence in 2-normed space, study of their relationship, and make some observations about these classes.
