One zinc-27 % aluminum alloy (ZA-27) with excellent corrosion resistance and high hardness is ZA-27, making it suitable for industrial applications such as vehicle parts. The alloy works better in tough mechanical conditions because it has carbide particles, like SiC or TiC, added to it, which make it harder, more resistant to wear, and improve its internal structure. Using Minitab statistical software, the design of experiments (DOE) was utilized to conduct studies with a statistical two-level factorial experimental design. The effect of three parameters, SiC particles percentage (X1), stirring speed (X2), and stirring time (X3), was studied on the tensile characteristics of the SiC-enhanced ZA-27. The ingot was smelted

The traditional healthcare sector has faced several challenges, such as poor health services, crowding and queuing at medical centers, and manual searches for or missing patient records; a smart health system is needed to overcome these challenges. This study presents the design and implementation of end-to-end IoT architecture, which is built by the integration of various open-source technologies. The pulse care system is implemented using Node.js and React.js, which offer features such as electronic health records (EHR), smart appointments, prescription documentation, and health monitoring.

Show MoreThe issue of noise transmission between residential units in high-rise buildings poses a significant challenge to privacy and auditory comfort, especially amid increasing urban expansion and population density. This study aims to address this problem by evaluating sound insulation strategies in high-rise residential units and assessing their alignment with international standards within local contexts. Six global residential projects were analyzed based on their adoption of advanced acoustic insulation solutions. The methodology involved examining key design elements such as the spatial distribution between quiet and noisy areas, and the use of insulation materials and techniques for walls, floors, ceilings, doors, and w

This study investigates the use of recycled plastic aggregate (RPA), as a partial replacement for conventional coarse aggregates by weight in lightweight concrete production. Concrete mixtures with different concentrations of RPA at (0, 15, 30, and 45%) were prepared and cured for 7, 14, 28, and 56 days. Including RPA into concrete reduced both density and compressive strength as the replacement level increased. Density decreased from 2,347 kg/m³ at 0% RPA to 1,895 kg/m³ at 45% replacement. Similarly, 28 days compressive strength decreased from 30.43 N

Recent advancements in nanotechnology have introduced various nanomaterials such as alumina (NA), carbon nanotubes (CNTs), and silica (NS) as potential asphalt modifiers. These materials possess unique properties that address challenges related to asphalt fatigue. However, their effectiveness depends on proper dispersion and mixing techniques. This review examines the mixing methods used for each nanomaterial to ensure uniform distribution within the asphalt matrix and maximize performance benefits. Recent research findings are synthesized to elucidate how these nanomaterials and their

Show MoreThis literature review investigates the seismic behavior of low-rise steel structural frames with fixed, pinned, and base-isolated column bases under single and successive earthquake excitations. Experimental shaking table tests and Abaqus finite element models are utilized to evaluate the impact of base flexibility on structural performance measures, including inter-story drift, base shear, and acceleration response. Base-isolated systems, including elastomeric, lead-rubber, and friction pendulum bearings, demonstrate superior energy dissipation capacity and reduced seismic demand compared to traditional fixed and pinned bases. While pinned bases offer rotational flexibility that reduces moment concentration, they are s
