Synthesis and Characterization of Cobalt Oxide Nanoparticles and Cobalt Oxide/MWCNTs as a Binary Nanocomposite
Safa Yassin, Haider Ghrabee, Donia Abdulateef (Author)
September 2024 ,Pages 13.0-23.0

Abstract: There is a rising interest in nanocomposites with unanticipated features that are different from traditional materials to fulfill the demands of these applications. Cobalt oxide (Co3O4) nanoparticles, and cobalt oxide with multi-walled carbon nanotubes (Co3O4/ MWCNTs) as nanocomposites were created. In this study, cobalt oxide nanoparticles (Co3O4 NPs) were synthesized via co-precipitation method chemical using CoCl2 salt as a source of cobalt nanoparticles and sodium hydroxide solution as a factor agent at room temperature. The cobalt hydroxide (Co(OH)2) precipitate was obtained, then it calcinated the cobalt hydroxide precipitate at 600°C to obtain the cobalt oxides nanoparticles (Co3O4 NPs). Also, MWCNTs were prepared by a locally manufactured reactor at 423 k. Binary composites were prepared by solution method using cobalt oxide nanoparticles dispersion over MWCNTs surfaces. The structural, morphological, and spectral properties were confirmed and investigated by using FE-SEM, Raman spectroscopy, and (XRD), respectively. The surface area and pore size obtained by BET and BJH showed that the binary nanocomposites (Co3O4/MWCNTs) have a higher surface area than their pristine cobalt oxide and multi-walled carbon nanotubes nanoparticles. The adsorption processes of nanocomposites have attracted significant care from the scientific public because of their distinctive possessions and aptitude to reduce and adsorb Cu+2 and Ni+2 as heavy metals from water pollution. As a result, Co3O4 and its nanocomposite with MWCNTs were used to remove copper and nickel ions from the dilute aqueous solution.

Deep Generative Adversarial Networks For Noise Reduction in Medical Images: A Review
Zahraa Hussien, Abbas Al-Asadi (Author)
September 2024 ,Pages 24.0-34.0

Abstract: Imaging is a vital component of the diagnostic and early detection processes for many medical disorders. However, the noise in the images can sometimes interfere with the accuracy of the diagnosis. Speckle noise, Poisson noise, salt and pepper noise, and Gaussian noise are a few instances of these disturbances, which are produced by imaging techniques and reduce diagnostic accuracy as well as image quality. Noise reduction methods, such as spatial filtering and transformational domain filtering, have a lot of problems when dealing with various kinds of noise. With the growth of deep learning, especially generative adversarial networks, the capabilities of image noise reduction are even superior to those of traditional techniques. This study compares the efficacy of GAN techniques with traditional de-noising techniques and illustrates the effects of various noise sources on medical imaging. Besides that, it describes how the GAN accomplishes the noise reduction task in medical imaging by discussing its advantages, uses, and efficiency in comparison to other techniques. The study's outcomes revealed a new approach to using GAN to filter out the noise in medical images and the possibility of utilizing this technique in real-world cases to generate accurate diagnosis and analysis. But, in addition to that, it serves as a passageway to more in-depth research that focuses on medical image enhancement and patient healthcare.

Finding the Exact Solution of the Dynamic Model for the Spread of Computer Viruses Using the Homogeneous Balance Method
Sadoon Ali, Ahmed Ghatet (Author)
September 2024 ,Pages 35.0-44.0

Abstract: In this paper, we solved the SEIR system (a system that describes the spread of viruses in computers) using the homogeneous balance method, which is one of the methods concerned with finding the accurate solution for equations of various types, linear, non-linear, partial, and ordinary.  SEIR is a system of nonlinear partial equations. Studying this system helps reduce the damage caused by viruses to computers and the problems they cause to devices by predicting the presence of viruses before they spread to computers. The system was solved and the exact solution of the SEIR system was found. The effect of the parameters  was studied, and it was found that the smaller these parameters were (close to zero), the slower the viruses leaked into computers. The impact of parameters and how much performance they can cause to devices is explained using 3D graphics. It has become clear that these viruses pose a great danger to devices, so studying them is a topic that deserves attention.

A Fuzzy-Based Expert System for Prenatal Care Advice
Lukman OGUNDELE, Adekunle Ejidokun, Femi Ayo, Abass TAIWO (Author)
September 2024 ,Pages 85.0-100.0

Abstract: Prenatal care refers to medical attention that a woman receives to maintain her health and the health of her unborn child. The traditional methods of medical experts in prenatal care advice can sometimes be inadequate and less efficient due to a number of factors. One major issue is the lack of knowledge in the area of prenatal care for most medical experts, which hinders quality advice to pregnant women. In order to overcome some of these challenges, computer-based methods for any health issue have been proposed, which have shown to be more effective and are being utilized more frequently to raise the standard of medical care. This research work proposes the use of an expert system approach based on a forward-chain inference engine. Java programming language was used in the implementation of the proposed expert system. The expert system for prenatal care recommendations had a mean satisfaction level score of 3.87 out of a possible 5.0, according to the assessment results based on survey opinions. This suggests a 77.5% level of user satisfaction. The performance level of the expert system in providing quality advice to pregnant women indicates that it is faster, more sensitive, and more reliable than the traditional method of using medical experts to provide prenatal care advice.
