     The symmetry energy accounts for the rise in nuclear matter's energy as the ratio of protons to neutrons deviates from equality. Using the Coherent Density Fluctuation Model (CDFM), the nuclear symmetry energy (S), neutrons pressure (Po), and asymmetric compressibility (ΔK) in argon isotopes were calculated. The in-depth study also investigates the correlation between the neutron skin thickness (ΔR_n) and the properties of the nuclear symmetry energy's density dependence for Ar isotope chains. In addition, the significance of the neutron-proton asymmetry, the nuclear symmetry energy's mass dependency, and the neutron skin's thickness are investigated. Analysis of density-dependent nuclear symmetry energy characteris

Wind energy is considered the world's second sustainable energy source after solar energy was utilized to generate electrical energy. Iraq's accession to the Paris Climate Agreement encouraged the government to involve small and large projects in generating electricity from renewable energy sources, including wind. This requires preliminary studies on the feasibility of investing in renewable energy sources in Iraq. This work was concerned with analyzing wind energy for the city of Sinjar-Nineveh in northern Iraq to determine the extent of the potential of wind energy in generating electrical energy in that region. The wind speed and direction in the area were analyzed at three altitudes for 44 years. The results showed that the northwes

Diyala is one of Iraq's largest citrus producer areas, characterized by many orange trees and sour and sweet lemon trees embraced by palm orchards. The absence of outstanding quality and spectral remotely sensed information makes distinguishing between distinct fruit tree species with similar spectral and spatial characteristics difficult, particularly for broadleaf evergreen trees. This work provides a unique decision technique for mapping the geographical distribution of citrus trees using spectral reflectance characteristics taken from Landsat 9 band spectral indices data. The spectrum reflectance of citrus trees was calculated using a seasonal series of data (2018-2023) of spectral indicators such as the Normal Difference Vegetation

     In this work, the influence of positive and negative corona discharges on the variation of air gap discharge characteristics with applied voltage under atmospheric pressure in the tap water electrodes system has been investigated. The discharge characteristics included emission spectra, electron temperature, electron number density, Debye length and plasma frequency. The results show no effect of polarity of space charge on the emission peaks. While the intensity of emission peaks increases when the presence of the negative space charge forms the negative corona discharge. Increasing the applied voltage increases the (T_e , n_e , ) plasma parameters while parameters (λ_D , N_D) decrease.

     This work examines novel conjugate gradient methods. To address unconstrained optimization problems and optimize the training of neural networks. The methodologies employ advanced derivative-based techniques to enhance optimization outcomes. The novel approach employs any line search to guarantee adequate descent. Moreover, we prove that, given specific assumptions, our proposed method converges universally. Experimental evidence has demonstrated that our proposed approach is superior in terms of efficiency and robustness compared to traditional conjugate gradient approaches for training neural networks and solving unconstrained optimization issues.

     Feature Selection (FS) is a technique that removes redundant and unnecessary characteristics from the original data to identify the smallest subset of features. Its goal is to make classification algorithms more efficient. Rough set theory (RST) offers a reliable route to feature selection; however, it resorts to comprehensive searches to find all subsets of features and dependence to assess them. However, due to its high cost, the entire search may not be viable for huge data sets. As a result, meta-heuristic algorithms, particularly Nature-Inspired Algorithms, are commonly employed to substitute the RST reduction step. The Hybrid Rough Set based Binary Grasshopper Optimization Algorithm (HRBGOA) was proposed as a FS approach f

Examination of skewness makes academics more aware of the importance of accurate statistical analysis. Undoubtedly, most phenomena contain a certain percentage of skewness which resulted to the appearance of what is -called "asymmetry" and, consequently, the importance of the skew normal family . The epsilon skew normal distribution ESN (μ, σ, ε) is one of the probability distributions which provide a more flexible model because the skewness parameter provides the possibility to fluctuate from normal to skewed distribution. Theoretically, the estimation of linear regression model parameters, with an average error value that is not zero, is considered a major challenge due to having difficulties, as no explicit formula to calcula
