Partitioning bases of topological spaces [PDF]
Electronic Notes in Discrete Mathematics, 2013 We investigate whether an arbitrary base for a dense-in-itself topological space can be partitioned into two bases. We prove that every base for a T_3 Lindel f topology can be partitioned into two bases while there exists a consistent example of a first countable, 0-dimensional, Hausdorff space of size continuum and weight _1 which admits a point ...

Omnidirectional Vision Based Topological Navigation [PDF]
International Journal of Computer Vision, 2007 In this work we present a novel system for autonomous mobile robot navigation. With only an omnidirectional camera as sensor, this system is able to build automatically and robustly accurate topologically organised environment maps of a complex, natural environment.

Hybrid topologies on the real line
Applied General Topology, 2023 Given A ⊆ ℝ , the Hattori space H(A) is the topological space ( ℝ , τA ) where each a ∈ A has a τA -neighborhood base { ( a − ε , a + ε ) : ε > 0 } and each b ∈ ℝ − A has a τA -neighborhood base { [ b , b + ε ) : ε > 0 } .

Topological Design of a Mortar Base Plate under Impact Loads
Shock and Vibration, 2021 In this work, the topology optimization of a mortar base plate is analysed under impact loading conditions. Usually, in this case, only ordinary topology optimization under volume constraints is considered.

Topological-insulator-based terahertz modulator [PDF]
Scientific Reports, 2017 AbstractThree dimensional topological insulators, as a new phase of quantum matters, are characterized by an insulating gap in the bulk and a metallic state on the surface. Particularly, most of the topological insulators have narrow band gaps, and hence have promising applications in the area of terahertz optoelectronics.

Separation functions and mild topologies
Analysis and Geometry in Metric Spaces, 2023 Given MM and NN Hausdorff topological spaces, we study topologies on the space C0(M;N){C}^{0}\left(M;\hspace{0.33em}N) of continuous maps f:M→Nf:M\to N. We review two classical topologies, the “strong” and the “weak” topology. We propose a definition of “

Journal of Marine Science and Engineering, 2023 Ocean wireless sensor networks (OWSNs) play an important role in marine environment monitoring, underwater target tracking, and marine defense. OWSNs not only monitor the surface information in real time but also act as an important relay layer for ...

Topology-based signal separation
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2004 Traditional noise-filtering techniques are known to significantly alter features of chaotic data. In this paper, we present a noncausal topology-based filtering method for continuous-time dynamical systems that is effective in removing additive, uncorrelated noise from time-series data.

On The Stability Of Fixed Points In Topological Spaces
Journal of Kufa for Mathematics and Computer, 2014 In this papers we introduced new concepts of stability: strongly stable, c-stable, and c-strongly stable. We discussed the stability of fixed points with respect to each of a topology and a base for that topology.
