Ductility Tuning via Cluster Network Characteristics of Porous Components

Advanced Materials Technologies, EarlyView.
Network optimization via cluster characteristics induced by interaction of stress concentration is proposed, demonstrating increased cluster size and dispersion in non‐uniform porous components. The optimized structures exhibit, for the first time, that enhanced ductility and damage progression is controllable through zigzag cluster network designed by

ACCELERATED FRACTAL ENCODING VIA DOMAIN CLASSIFICATION

Science Journal of University of Zakho
The story of fractal image compression is that the image to be compressed is partitioned into many blocks (range pool). Domain pool is created from range pool. Then, each range block is compared with all domain blocks, searching for the best match. This

Map online system using internet-based image catalogue [PDF]

, 2005
Digital maps carry along its geodata information such as coordinate that is important in one particular topographic and thematic map. These geodatas are meaningful especially in military field.

Reprogramming the Myocardial Infarction Conductive Microenvironment with Superconductive Ionic Patch for Cardiac Function Repair

Advanced Science, EarlyView.
A super‐conductive ionic patch reprograms the post‐infarction microenvironment by enabling stable ionic migration and electrical signal transmission within damaged myocardium. The patch rapidly adheres to cardiac tissue, enhances conduction velocity, suppresses excitation‐contraction decoupling, and promotes structural and functional cardiac repair in ...

Speeding-Up Fractal Image Compression by Using Classification Range Blocks [PDF]

Engineering and Technology Journal, 2013
In fractal compression technique, an image is partitioned into sub blocks called range blocks, each of which is encoded by matching it (after an appropriate affine transformation) with a block chosen from a large pool of domain blocks, which is ...

Numerics and Fractals [PDF]

, 2014
Local iterated function systems are an important generalisation of the standard (global) iterated function systems (IFSs). For a particular class of mappings, their fixed points are the graphs of local fractal functions and these functions themselves are

High Velocity Dust Collisions: Forming Planetesimals in a Fragmentation Cascade with Final Accretion

, 2009
In laboratory experiments we determine the mass gain and loss in central collisions between cm to dm-size SiO2 dust targets and sub-mm to cm-size SiO2 dust projectiles of varying mass, size, shape, and at different collision velocities up to ~56.5 m/s ...

Sulfate‐Directed Silver Dendrites with Enhanced Stability for Ultrasensitive SERS‐Based Therapeutic Drug Monitoring

Advanced Science, EarlyView.
This study presents sulfate‐directed silver dendrites (s‐AgDs) as oxidation‐resistant SERS substrates with long‐term stability, reproducibility, and sub‐picomolar sensitivity. Sulfate ions guide anisotropic growth and protect the surface, enabling improved performance over 7 months under ambient conditions.
