Early and accurate detection of melanoma skin cancer using hybrid level set approach [PDF]
Frontiers in Physiology, 2022 Digital dermoscopy is used to identify cancer in skin lesions, and sun exposure is one of the leading causes of melanoma. It is crucial to distinguish between healthy skin and malignant lesions when using computerised lesion detection and classification.

Level-Set-Based Kidney Segmentation from DCE-MRI Using Fuzzy Clustering with Population-Based and Subject-Specific Shape Statistics [PDF]
Bioengineering, 2022 The segmentation of dynamic contrast-enhanced magnetic resonance images (DCE-MRI) of the kidney is a fundamental step in the early and noninvasive detection of acute renal allograft rejection. In this paper, a new and accurate DCE-MRI kidney segmentation

Applications of $$\alpha$$ α -level neutrosophic set and strong $$\alpha$$ α -level neutrosophic set
Discover Applied SciencesIn this article, we present an innovative extension of the concept of $$\alpha$$ α -level neutrosophic set (NS). Building upon the pioneering work of Johnson Awolola [14] in 2020, who initially defined $$\alpha$$ α -level NS, our research introduces a ...

A Vaporization Model for Continuous Surface Force Approaches and Subcooled Configurations
Fluids, 2023 The integration of phase change phenomena through an interface is a numerical challenge that requires proper attention. Solutions to properly ensure mass and energy conservation were developed for finite difference and finite volume methods, but not for ...

Level sets of the Takagi function: local level sets [PDF]
Monatshefte für Mathematik, 2012 The Takagi function : [0, 1] \to [0, 1] is a continuous non-differentiable function constructed by Takagi in 1903. The level sets L(y) = {x : (x) = y} of the Takagi function (x) are studied by introducing a notion of local level set into which level sets are partitioned.
