Some Properties of C ∗ -Graded Metric Spaces and Fixed Point Results

open access: yesJournal of Mathematical Extension, 2010
In this paper, by using of C ∗ -algebra we give a metric with range in positive unit ball of a C ∗ -algebra. Indeed this is a generalization of a fuzzy metric space.

POTENSI DAN TINGKAT PEMANFAATAN SUMBERDAYA IKANDEMERSAL DI PERAIRAN KABUPATEN PEKALONGAN

open access: yesAgriekonomika, 2012
Pekalongan Regency seawaters is one of potential demersal fish distribution area. If resources utilization are uncontrol, the resources will be threatened by fishing effort increase. Information about potency and utilization rate should be known.

Bayesian Non-Parametric Inference for Multivariate Peaks-over-Threshold Models

open access: yesEntropy
We consider a constructive definition of the multivariate Pareto that factorizes the random vector into a radial component and an independent angular component. The former follows a univariate Pareto distribution, and the latter is defined on the surface

Quasi-homogeneous associative functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1998
A triangular norm is a special kind of associative function on the closed unit interval [0,1]. Triangular norms (or t-norms) were introduced in the context of probabilistic metric space theory, and they have found applications also in other areas, such ...

Graininess of RGB-Display Space

open access: yesi-Perception, 2018
RGB –display space, that is, the ‘ RGB –cube’, was sampled at 3,000 locations, uniformly and randomly distributed. Fifty observers contributed 60 samples each. At each location, participants synthesised a copy of the target, using a generic colour picker.

On the extremal semi-Lipschitz functions

open access: yesJournal of Numerical Analysis and Approximation Theory, 2002
The extremal elements of the unit balls of Banach spaces play an important role in the study of the geometry of the space as well as in various applications.

Unit Size Determination for Exploratory Brain Imaging Analysis: A Quest for a Resolution-Invariant Metric

open access: yesMathematics
Defining an adequate unit size is often crucial in brain imaging analysis, where datasets are complex, high-dimensional, and computationally demanding. Unit size refers to the spatial resolution at which brain data is aggregated for analysis.

On the boundary behavior of the holomorphic sectional curvature of the Bergman metric

open access: yesLe Matematiche, 2006
We obtain a conceptually new differential geometric proof of P. F. Klembeck’s result (cf. [9]) that the holomorphic sectional curvature k g (z ) of the Bergman metric of a strictly pseudoconvex domain Ω ⊂ ℂ n approaches −4/(n + 1 ...

Designing a TPMS metamaterial via deep learning and topology optimization

open access: yesFrontiers in Mechanical Engineering
Data-driven models that act as surrogates for computationally costly 3D topology optimization techniques are very popular because they help alleviate multiple time-consuming 3D finite element analyses during optimization.
