Two distinct redistribution grids - adaptation techniques, spring analogy and elliptic grid generator are applied to two-dimensional steady, inviscid, shocked flows, and the ability of each technique is examined and compared. Euler equations are solved base on Roe's Reimann solver approach to simulate supersonic flow around a sphere, transonic flow about an airfoil and supersonic flow in a symm...

The Set Partitioning in Hierarchical Trees (SPIHT) approach for still image compression proposed by Said and Pearlman [8], is one of the most efficient embedded gray image compression schemes till date. The algorithm relies on a very efficient scanning cum bit-allocation scheme for quantizing the coefficients obtained by a wavelet decomposition of an image. In this paper, we adopt this scheme t...

Flexible-grid wavelength-division multiplexing is a powerful tool in lightwave communications for maximizing spectral efficiency. In the emerging field of quantum networking, need effective resource provisioning particularly acute, given generally lower power levels, higher sensitivity to loss, and inapplicability digital error correction. this Letter, we leverage flex-grid technology demonstra...

High penetration level of renewable energy sources and introduction controllable loads will result in significant harmonic emissions sag swell events the future electricity networks. Development methods for high performance simultaneous estimation frequency amplitude is required stable operation networks since zero crossing detection method (which widely used nowadays industry) not accurate eno...

Smart grid concept is introduced to modify the power grid by utilizing new information and communication technology. Smart grid needs live power consumption monitoring to provide required services and for this issue, bi-directional communication is essential. Security and privacy are the most important requirements that should be provided in the communication. Because of the complex design of s...

The International Thermonuclear Experimental Reactor (ITER) is a cutting-edge project that aims to develop sustainable energy source by harnessing the power of nuclear fusion. One key challenges in development ITER complex electrical grid required support its operations. To address this challenge, digital twin (DT) Central Solenoid (CS) Converter Power Supply has be developed, and real-time sim...

Autonomous robots must be able to learn and maintain models of their environments. Research on mobile robot navigation has produced two major paradigms for mapping indoor environments: grid-based and topological. While grid-based methods produce accurate metric maps, their complexity often prohibits efficient planning and problem solving in large-scale indoor environments. Topological maps, on ...

A simple way to avoid idle processors in implementing the multigrid method on a parallel computer is to select a proper ner grid as the new coarsest grid. For clarity, the variant of the V-cycle generated by this approach is called the U-cycle in this paper. It is proved that the U-cycle with a ner coarsest grid can have a faster convergence rate, and the coarsest grid equations of the U-cycle ...
