Effect Of Annealing On The Structural, Surface Morphology And Optical Properties For Cdo:Pbo Composite Thin Films, Rasha Hamid Ahmed, Maad Mohammed Ameen Jul 2021

Effect Of Annealing On The Structural, Surface Morphology And Optical Properties For Cdo:Pbo Composite Thin Films, Rasha Hamid Ahmed, Maad Mohammed Ameen

Al-Qadisiyah Journal of Pure Science

Thin films of pure cadmium oxide films (CdO) and composite with lead oxide (PbO) at different atomic ratios were prepared by pulsed laser deposition under vacuum usingpulsed laser of ND-YAG from CdO and CdO:PbO targets. The prepared thin films were characterized by different technique before and after annealing. The X-ray diffraction shows polycrystalline structures of cubic CdO phase convert tosample of mixed phases for composites. The AFM images illustratedecreasing the particle diameter and increasingsurface roughness with increasing the PbO ratio in composite. While, annealing cause to increase the particle size and reduce roughness. The optical absorbance increased with the PbO …


Quantitative And Qualitative Comparison Study Between Classification Methods On Normal And Abnormal (With A Coronavirus ) Lung Images, Hala Kadhim Hasan, Ayad A. Al-Ani, Noor Z. Al-Khazraji Jul 2021

Quantitative And Qualitative Comparison Study Between Classification Methods On Normal And Abnormal (With A Coronavirus ) Lung Images, Hala Kadhim Hasan, Ayad A. Al-Ani, Noor Z. Al-Khazraji

Classification is concerned with establishing criteria that can be used to identify or distinguish different populations of objects that appear in images. In this paper Supervised and unsupervised classification method applied on normal, abnormal (with a coronavirus) ct- lung images (which it took from Al shaikh zaeid Hospital) to study the quantitative and qualitative properties of these two categories. The analysis of performance with default quantitative parameters revealed that (kurtosis, skewness, entropy, Stander deviation (STD), mean). We found that: Qualitative (as seen) of abnormal lung images after applying Supervisors classification are better than the qualitative of abnormal lung images after …


Applying Many Of The Methods To Synchronization Of Chaoson The Electronic Circuit Chaotic From Type Memductance, Abo-Talib Y. Abbas Jan 2021

Applying Many Of The Methods To Synchronization Of Chaoson The Electronic Circuit Chaotic From Type Memductance, Abo-Talib Y. Abbas

Al-Qadisiyah Journal of Pure Science

the attractor chaotic from the type Chua’ attractors, was obtained at study one types of electronic circuit chaotic affiliate for family Chua’ circuit, where, the nonlinear part from type memductance, after we succeeded in found the attractor chaotic for circuit, we study many from the methods of synchronization chaos. It was the first method is Pecora and Carroll (PC), but it failed to reach for case complete synchronization, because the ratio of error not equal zero. The same as of result can reach for it, when we applying the method of adaptive-observer, at choose the value of feedback gain c=10. …
