The saturated magnetization (mtot) and the Gilbert damping constant (α) are two key factors that determine critical current density of reversal in spin-transfer-torque magnetic memory devices. Here, this study demonstrates efficient modulation these parameters by tunning composition Heusler Co3–xFexAl thin films, utilizing x-ray circular dichroism technique ferromagnetic resonance measurements....

Structural radar absorber has important application in stealth field for its ability to effectively absorb incoming wave and bear the load at same time. Metasurface absorbers can achieve nearly-perfect absorption of wave, have characteristics light weight thin structure, but their bandwidth are usually narrow. To solve this problem, a new method broadening metasurface is proposed work. With var...

The vehicle driving simulator (VDS) is a virtual reality-based system that provides drivers and passengers with feeling similar to the actual vehicle. However, motion of VDS has limitations in providing same as due its limited kinematics dynamic characteristics. In order solve these problems limit kinematic workspace, washout algorithm needed. since classical causes sickness time delay signal d...

Optimal reactive power dispatch (ORPD) intended for reducing the real losses of transmission scheme remains one supreme concerns research community to explore competence schemes. Numerous systems have been deliberate increase performance optimization method in tunning operational variables as well explored through estimating final results. The offering a novel approach based on entropy evolutio...

Rectification of interacting Brownian particles is investigated in a two-dimensional asymmetric channel the presence an external periodic driving force. The force can break thermodynamic equilibrium and induces rectification (or finite average velocity). spatial variation shape leads to entropic barriers, which indeed control particles. We find that by simply tunning frequency, amplitude, chann...

Recently, there is a revival of interest in low-rank matrix completion-based unsupervised learning through the lens dual-graph regularization, which has significantly improved performance multidisciplinary machine tasks such as recommendation systems, genotype imputation and image inpainting. While regularization contributes major part success, computational costly hyper-parameter tunning usual...

Bamboo, as a fast-grown forest resource, can be functionalized by metal–organic frameworks (MOFs) with various potential applications. However, the stability of MOFs immobilized on bamboo surface remains to improved. In this work, MOF199, known HKUST-1, was in situ anchoring moso via regulating pretreatment and green two-step synthesis route. The route completed under room temperature both prec...

The proposed loaded with constant load impedance. To improve the performance of microgrid, optimal control algorithm utilizing Cuckoo Search Algorithm (CSA) adapted. It has many merits such as fast convergence, simple tunning, high effici...

The early Universe inflation [11] is well known as a promising theory to explain the origin of large scale structure of the Universe, a causal theory for the origin of primordial density fluctuations which may explain the observed density inhomogeneities and cosmic microwave fluctuations in the very early Universe, and to solve the early universe pressing problems for the standard hot big bang ...

Metal-free catalysts, such as graphene/carbon nanostructures, are highly cost-effective to replace expensive noble metals for CO2 reduction if fundamental issues, such as active sites and selectivity, are clearly understood. Using both density functional theory (DFT) and ab initio molecular dynamic calculations, we show that the interplay of N-doping and curvature can effectively tune the activ...
