Abstract Depression is a multifactorial disease with unknown etiology affecting globally. It’s the second most significant reason for infirmity in 2020, about 50 million people worldwide, 80% living developing nations. Recently, surge depression research has been witnessed, resulting multitude of emerging techniques developed prediction, evaluation, detection, classification, localization, and treatment. The main purpose this study to determine volume conducted on different aspects such as...
Abstract This research aims to investigate the influence of model parameters and fractional order on a novel mathematical with tangent hyperbolic memristor. investigation conducted by applying Lyapunov exponents bifurcation analysis. We utilize exponent theory understand characterize these chaotic behaviors under indices. The exponent, bifurcation, phase diagrams have been depicted explore intricate dynamics system governed equation. A approach termed Atangana-Baleanu-Caputo (ABC) derivative...
The purpose of the present work was to monitor reliability calibration-free laser-induced breakdown spectroscopy (CF-LIBS) by comparing results with inductively coupled plasma - mass spectrometry (ICP-MS). For laser ablation studies, generated a Q-switched Nd: YAG laser, and emission spectra alloy sample were recorded using set Avantes spectrometers covering wavelength region from 250 870 nm. Optical confirmed that copper iron are major constituents while traces sodium magnesium also...
The analysis of Lakhra Coal to determine its total carbon content and ash is reported by calibration-free laser-induced breakdown spectroscopy (CF-LIBS). in coal are key parameters for efficient energy u sepower plants. optical emission spectrum contains spectral lines Ca, Si, Fe, Ti, Mg, Na, K, Li, Al, C together with traces Ba Sr. excitation temperature electron number density the laser-produced plasma were estimated using a Boltzmann plot Stark broadened Hα line, respectively....
In this contribution, we present analysis of the total carbon contents and major constituents in Reference Coal sample known concentration (SARM 20) Pakistani Thar samples using laser induced breakdown spectroscopy (LIBS). A high-power Q-switched Nd:YAG Laser, (532nm, 5ns pulse width 10 Hz repletion rate) was used to produce plasma air optical emission spectra were registered a HR 4000 spectrometer covering wavelength region from 200 nm 1100 nm. The spectrum produced plume contains atomic...
The available software to study the spectroscopic characteristics of atoms, ions, and molecules runs on a server, e.g., general-purpose atomic structure package (GRASP) R-matrix method. A Python program has been developed compute Transition Probabilities, oscillator strengths, Line matrix elements, radii orbit for lithium its iso-electronic sequence. is straightforward, easily applicable without installation, uses built-in libraries. It can be run personal computers core I3 above. effective...
Nitrogen is one of the key elements in evolution and formation stellar objects. Earth's atmosphere contains 21% oxygen 78% nitrogen; these two gases give rise to aurora when ions solar wind ionosphere collide with them. Some aerosols made nitrogen are also found atmosphere. Nitrogen, hydrogen, carbon, main contributors origin life on Earth. The spectrum ion (N V) has been studied using Quantum defect theory (QDT) Numerical Coulombic approximation (NCA). N V electrons core, nucleus, electron...
