Analysis of Sound Transmission Loss in Hybrid Mufflers for Automotive Applications
Abstract: An exhaust system's noise level can be reduced with the use of a muffler. There is general recognition that baffled exhaust mufflers reduce noise emissions and increase the loss of sound transmission. The reduction of sound transmission can be further achieved by inserting sound-absorbing materials inside the muffler. Exhaust muffler systems with strategically positioned baffles have been shown to effectively reduce noise emissions, thereby improving acoustic performance. Baffles divert and …

Machine Learning Optimization for VARTM Carbon Polymer Laminates
Abstract: Vacuum-assisted resin transfer moulding (VARTM) is a key low-cost, out-of-autoclave process for manufacturing large-scale carbon-fibre reinforced polymer (CFRP) laminates crucial to aerospace wings, wind-turbine blades, marine hulls, and automotive structures. Unpredictable resin flow often leads to voids, dry spots, and race-tracking defects, resulting in 27.9% scrap rates and lengthy, costly trial-and-error design cycles. Although surrogate models provide rapid impregnation predictions for simple flat-plate geometries, vision-based monitoring is limited to idealized …

Hematological and Biochemical Changes in the Freshwater Fish, Pseudetroplus Maculatus Exposed to Sublethal Concentrations of Chlorpyrifos
Abstract: Sublethal effects of chlorpyrifos on hematological and biochemical parameters were assessed in the freshwater fish, Pseudetroplus maculatus. Fish were exposed to chlorpyrifos at two sublethal concentrations, 0.661 µg/L (one-tenth of LC50—96 h) and 1.32 µg/L (one-fifth of LC50—96 h), for 15 and 30 days maintaining the control group. Blood collected from the control and treated groups were used for analyzing the hematological and biochemical parameters. Chlorpyrifos exposure significantly (P<.05) decreased …

Effect of Improvement of Collapsible Soils with Bitumen Emulsions on Collapsibility Rate for Varying Degrees of Saturation
Abstract: Collapsible soils are one of many problematic soils in Iraq. Many foundation failure problems that occurred in Iraq are associated with percolation of water; the change in the degree of saturation can affect the stability of these soils and may encounter large volumetric change. A series of tests conducted on collapsible soil using oedometer apparatus and the settlement–time curves are determined accurately, then each test is determined to a different …
