Öğe Design and Simulation of a Biocompatible Prosthesis Ti-15Mo-XTa Alloy: An Analysis of Mechanical Integrity Using Finite Element Modeling(Springer Science and Business Media Deutschland GmbH, 2024) Saud, A.N.; Majdi, H.S.; Koç, E.; Al, Maamori, M.The main focus of this work is the development and simulation of a prosthesis using a high entropy alloy known as Ti-15Mo-XTa. The selection of this alloy is based on its compatibility with the human body, which is a crucial factor when choosing materials for medical implants. Traditional metal implants can cause several problems for patients, including toxic reactions from the release of metal ions, wear and tear of joint replacements from movement, and structural failure from repetitive loading. To address these concerns, the present study creates a three-dimensional finite element model of the prosthesis using COMSOL software. The model includes both isotropic and anisotropic materials and is subjected to various mechanical loads based on experimental studies. The finite element method is used to analyze the distribution of stress and strain across adjacent elements of the prosthesis. By simulating the behavior of the prosthesis under different loading conditions, valuable insights into its performance and durability can be gained. To assess the static design, the prosthesis is tested using COMSOL simulation software and subjected to loading conditions of 70, 90 and 110 kg. The objective of this assessment is to determine the robustness and ability of the design to withstand real-world mechanical demands. By conducting these simulations and tests, the researchers hope to contribute to the development of improved prostheses that can offer better functionality, longevity and overall patient satisfaction. © 2024, The Author(s), under exclusive license to Springer Nature Switzerland AG.Öğe The Impact of SMES Integration on the Power Grid: Current Topologies and Nonlinear Control Strategies(Springer Science and Business Media Deutschland GmbH, 2024) Khaleel, M.; Gulbudak, O.; Ayed, S.K.; Mustafa, M.A.S.; Majdi, H.S.; Habeeb, L.J.; Elmnifi, M.Superconducting magnetic energy Storage (SMES) has recently provided fast and effective relief on the power grid (PG). In addition to that, the power quality (PQ) issues affecting the PG continue to receive special attention. There is no doubt that the PQ issues are an important point concerning the effect on the power grid (PG) utility. In this context, this manuscript aims to demonstrate in-depth the configurations, characterization, and properties of SMES as a robust energy storage (ES) technology. The main objective of SMES can be achieved by delivering excellent performance to support the demand load. From this perspective, current topologies SMES-PG interconnection are developed to evaluate the effectiveness and performance-enhancing while supplying efficient energy using non-linear control strategy including sliding mode controller strategies, partial feedback linearization, control strategy, hysteresis controller strategy, robust controller strategy, and predictive controller strategy. To conclude, this manuscript investigates in detail to determine the applications of SMES-PG interconnection and future scope. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.Öğe Investigation of the Effect of Adding Tantalum on the Microstructure and Mechanical Properties of Biomedical Ti-15Mo Alloy(Springer Science and Business Media Deutschland GmbH, 2022) Majdi, H.S.; Saud, A.N.; koç, E.; Al, Juboori, A.M.Titanium alloys have great applications as biomaterials due to their high mechanical strength and density ratio, good corrosion resistance, and biocompatibility. Type ? alloys have aroused enormous interest in the development of biomaterials due to their low elastic modulus. This new class of alloys has been formed mainly by adding tantalum, molybdenum, proven not to have biocompatibility. Tantalum is an alloy hardening element, which can increase the mechanical strength of the material. At the same time, molybdenum is a strong ?-stabilizer, stabilizing the ? phase with 10% quickly. In this work, Ti-15Mo-xTa system alloys were produced by the powder metallurgy method. The result shows the prepared alloy presented the ?-phase grain structure, showing more excellent mechanical properties than pure titanium due to hardening in solid solution. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.Öğe Modification of Acrylic Paint by Acetamide to Be Antibacterial Used for Medical Applications(Springer Science and Business Media Deutschland GmbH, 2024) Al, Maamori, M.; Majdi, H.S.; Kareem, A.; Saud, A.N.This study aimed to develop an innovative approach to produce an organic antibacterial composite material by combining acrylic paint and acetamide through a simple mixing method. Acetamide, known for its potent antibacterial properties, underwent a thorough evaluation to assess its effectiveness in the composite. The antibacterial properties were evaluated using established methods such as the minimum inhibitory concentration (MIC) and the agar well diffusion test. These tests provided quantitative and qualitative measures of inhibitory activity against two common bacterial strains, namely S. aureus and S. epidermidis. The results showed a clear correlation between the concentration of acetamide in the composite and its antibacterial activity. Higher concentrations of acetamide led to a significant increase in the effectiveness of the composite material against the targeted bacterial strains. In addition to the antibacterial properties, the mechanical and physical properties of the composite material were also analyzed comprehensively. Parameters such as wettability, swelling ratio and chemical structure were thoroughly investigated using Fourier Transform Infrared (FTIR) analysis. This comprehensive characterization enabled a detailed understanding of the behavior and performance of the composite material. The results of this study are auspicious in the context of operating rooms. The proposed composite antibacterial polymer coatings, utilizing organic or inorganic agents at low concentrations, represent an effective solution to eliminate bacteria and maintain a sterile environment. These coatings can be applied to operating room walls and offer improved infection control and reduced bacterial contamination risk. © 2024, The Author(s), under exclusive license to Springer Nature Switzerland AG.Öğe An Optimization Approaches and Control Strategies of Hydrogen Fuel Cell Systems in EDG-Integration Based on DVR Technology(International Information and Engineering Technology Association, 2024) Khaleel, M.; Yusupov, Z.; Alderoubi, N.; Habeeb, L.J.; Elmnifi, M.; Mohammed, A.; Majdi, H.S.Electrical Distribution Grid (EDG) will be required to further enhance PQ while also providing higher-efficiency electrical technology.
