Radiative Hybrid Nanofluid Flow Over a Porous Riga Surface: A Fuzzy–ANN Modeling Approach
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This study proposes a fuzzy–ANN model to investigate the nonlinear thermal transport in a tangent hyperbolic (Tanh) hybrid nanofluid flow past a porous Riga surface, considering the effects of Rosseland diffusion, chemical reactions, and internal volumetric heating.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...

Proto‐Panic Modulation by Caffeine‐Proteinoid Complexes
Journal of Applied Polymer Science, EarlyView.Caffeine–proteinoid microspheres synthesized by thermal polymerization exhibit compartmentalized drug loading with encapsulation efficiencies of 61%–82% and triphasic release kinetics. Electrochemical monitoring reveals multi‐scale oscillatory dynamics consistent with chaotic and damped harmonic behavior, while Boolean logic operations demonstrate ...

From Fractal Geometry to Fractal Analysis
Applied Mathematics, 2016 Euclidian geometry pertained only to the artificial realities of the first, second and third dimensions. Fractal geometry is a new branch of mathematics that proves useful in representing natural phenomena whose dimensions (fractal dimensions) are non-integer values. Fractal geometry was conceived in the 1970s, and mainly developed by Benoit Mandelbrot.

Using fractal dimensions for characterizing intra-urban diversity. The example of Brussels [PDF]
The objective of this paper is to compare fractal-based parameters calculated by different fractal methods for urban built-up areas, and to link the observed spatial variations to variables commonly used in urban geography, urban economics or land use ...

The scale free and scale - bound properties of land surfaces: fractal analysis and specific geomorphometry from digital terrain models [PDF]
, 1990 The scale-bound view of landsurfaces, being an assemblage of certain landforms, occurring within limited scale ranges, has been challenged by the scale-free characteristics of fractal geometry.

Generalized Scheme For Fractal Based Digital Signature (GFDS). [PDF]
, 2007 This paper describes a new development in the cryptographic digital signature scheme based on Mandelbrot and Julia fractal sets. Recently it has been shown that it is possible to have digital signature scheme based on fractal due to the strong connection

Fractal Geometry as an Effective Heat Sink
Strojniški vestnik - Journal of Mechanical Engineering, 2022 "How long is the coast of Britain?" was the question stated by Mandelbrot. Using smaller and smaller rulers the coast length limits to infinity. If this logic is applied to the fractal heat sink geometry, infinite cooling capacity should be obtained using fractals with mathematically infinite surface area.

Analyzing urban sprawl patterns through fractal geometry: the case of Istanbul metropolitan area [PDF]
, 2008 Over the last decade, there has been a rapid increase in the amount of literature on the measurement of urban sprawl. Density gradients, sprawl indexes which are based on a series of measurable indicators and certain simulation techniques are some ...

VERMONT μQFR: Diagnostic Accuracy of Murray Law‐Based 2D‐μQFR Compared to 3D‐μQFR and vFFR
Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Murray law‐based quantitative flow ratio (μQFR) is an angiography‐derived physiological index that utilizes a single angiographic projection with artificial intelligence‐guided vessel segmentation. Aims To evaluate the diagnostic accuracy and time efficacy of 2D‐μQFR against wire‐based fractional flow reserve (FFR ≤ 0.80), compare ...
