Unfortunately, sometimes even the slightest movement or change in the conveyer can throw the belt off track. Traditional condition monitoring methods are difficult to achieve comprehensive and effective monitoring. In this paper a new design of the anti drift system is proposed. The design will depends on micro-controller, stepper motors and position sensor to work together as online monitoring and readjusting the belt conveyer. 2024-06-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/569 High Availability Through Failover Clustering: Implementation and Analysis for Oracle ADF Web Applications Mohammed Ahmed Mohammed Alata; MojtabaAltayeb Abdullatif This paper presents a failover clustering implementation for Oracle ADF web applications using Oracle WebLogic Server clusters and Oracle HTTP Server. Through experimental testing of server failure scenarios, we demonstrate that applications remain accessible as long as at least one cluster node is operational, achieving near-continuous availability. The research examines failover mechanisms, recovery times, and configuration requirements, providing a practical framework for implementing high-availability architectures in enterprise web applications. 2024-06-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/568 Elastic Properties of Fibrous Composite Materials Osama Mohammed Elmardi Suleiman Khayal; Haitham Abd-Elrahman Mansoor Taha The study evaluates various mechanical properties of composite materials, such as modulus of elasticity, tensile strength, and elongation at break, using tensile, compression, and bending tests. It also investigates vibration damping capacity and water absorption/loss. Composite laminates comprise multiple layers engineered to achieve specific mechanical characteristics, including in-plane stiffness and thermal expansion coefficients. Understanding these properties is essential for assessing a material’s suitability for different applications. The paper identifies two main failure mechanisms during low-velocity impact (LVI): intralaminar damage, which occurs within the composite layers (e.g., fiber and matrix failures), and interlaminar damage, notably delamination. The properties of composites are influenced by several factors, including the characteristics of constituent materials (including additives), fiber length, orientation, cross-sectional shape, fiber distribution, and the volume fractions of the fiber and matrix materials. 2024-06-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/567 A Review Study of Materials Testing in Hardness Osama Mohammed Elmardi Suleiman Khayal; Haitham Abd-Elrahman Mansoor Taha The main purpose of hardness testing is to evaluate a material’s suitability or treatment history, taking into account factors such as the indenter type, geometry, and applied load. Hardness tests are frequently used in quality control to ensure materials conform to client specifications and industry standards, which typically define acceptable hardness ranges. In engineering, achieving a balance between hardness and other material properties is vital, as harder materials can resist wear but may also be more brittle and less ductile. This consideration is especially critical in the aerospace sector, where materials face extreme conditions. Ultimately, in manufacturing, a material’s hardness significantly influences product quality, including its durability, functionality, and overall performance 2024-06-01T00:00:00Z
