Aluminium composites are remarkably used in automotive, aerospace, and agricultural sectors because of their lightweight with definable mechanical properties. The stir casting route was followed to fabricate cylindrical samples with base aluminium alloy LM4, LM4/SiC, LM4/Al2O3, and LM4/SiC/Al2O3. The tensile strength, compressive strength, hardness, and micro-structural analysis were performed on samples and Finite element analysis (FEA) was adopted to predict the failure modes of composites. The composites experimental results were found to be in line with the FEA results, however, the LM4/SiC/Al2O3 revealed better results on the mechanical properties when compared with other composite configurations. The mechanical properties improvement like hardness 5%-11%, tensile strength 10.26%-20.67%, compressive strength 15.19% - 32.58% and 71.52 - 82.1% reduction in dimension have been achieved in LM4/SiC/Al2O3 composite comparing to base metal. © 2024 SAE International.

The metal cutting process has been signed an improved surface finishing of components to minimize the assembling difficulties. The machining was performed in EN24 alloy steel using carbide inserts. The Central Composite Design (CCD) of Response Surface Methodology (RSM) was followed to determine the number of cutting trials. Twenty cutting trials were carried out by varying cutting speed, feed rate and depth of cut. The experiment results were analyzed in Design Expert −11 software and the developed regression models verified the competence of each input variable on responses. This research identifies the optimized level of cutting parameters to obtain better results on the surface roughness (SR), cutting tool temperature (CTT) and metal remove rate (MRR). The multi responses were enhanced with aid of a single solution by using the desirability approach. Optimal cutting parameters were found at 1000 rpm, 0.1 mm and 0.75 mm speed, feed rate and depth of cut respectively. The input factor of speed reveals the most significant contribution on surface finish and cutting tool temperature, however, depth of cut implies a better contribution to metal removal rate. The validation trial results are agreed with the predicted values. © 2022

Metal matrix composite processing allows the possibility of improving both mechanical and damping properties by selecting reinforcements which have high damping characteristics, hardness and strength. In this work, the effect of disperse SiC as passive agents on the dynamic properties such as damping ratio, loss factor and effect of damping factor on Al7075/Al2O3/SiC composite machinability was studied. The composite samples were fabricated as Al7075/5%Al2O3, Al7075/5%Al2O3/5%SiC, Al7075/5%Al2O3/10%SiC and Al7075/5%Al2O3/15%SiC as well subsequently experimented. The dynamic properties were found using free vibration test approach and the hysteresis loop method. Further, the machinability in end milling operation was accessed by experimentation with the surface finish as the parameter under scrutiny. The composite Al7075/5%Al2O3/5%SiC has better damping ratio comparing to others, also the composite with the best damping capacity produces a fine surface finish during machining. Due to the self damping characteristics of the composite reduces the chatter during machining process such that the surface finish and dimensional stability was improved on the machined components. © 2024 SAE International.

This study investigates the mechanical characteristics of an aluminium metal grid composite strengthened with graphite and palm stalk ash. The mechanical characteristics of the samples were examined after adding various amounts of graphite and palm stalk ash to the aluminium metal matrix composite. Stir casting is used to create the hybrid metal composite made up of aluminium. Stir casting is a productive process that is most frequently used to create aluminium hybrid composites. Stir casting is a fluid-state technology in which various reinforcements are mixed with the liquid metal using mechanical stir casting processes after being dried out in a furnace. Thus, the molten composite of hybrid metals was poured into the mould, separated, and cooled. The mechanical properties of the aluminium half breed metal grid composites were noted by conducting tests such as hardness test (HRF), Ultimate Tensile strength (as per ATSM E8), impact test and the microstructure of the samples under different magnification in which the microstructure can be used for particle counting and size determination and for process control. The result obtained from the samples by conducting the tests indicated that the hardness increases and decreases at different proportions and shows similar for both the tensile and impact test. Finally in this evaluation the test results shows the effects of palm stalk ash on the aluminium 6061 metal matrix composite reinforced with graphite. © 2024 IEEE.

Dampers were used to control the vibration in any system. It performs absorbing shock due to sudden shock or it supports the system in a continuous shock. Pneumatic and hydraulic dampers are the most commonly found dampers, but in recent years' electrical dampers were started to raised, this uses some electrical powders or iron powders which absorbs the shocks or vibration when an electrical signal is passed. In advanced level magneto-rheological fluid acts as a damping fluid which forms magnetic chains when electromagnetic induction takes place if an electrical signal is passed to the electromagnetic coil. In this research work, a magneto-rheological damper was prepared for the vibration control in automotive shocks. Here the damper uses an in-house prepared MR fluid and their characteristics were studied and FEA tool was used to predict the magnetic properties in MR damper, which can be used to redesign the damper or MR fluid can be improved in such a way. © 2024 IEEE.

In radial distribution system, reconfiguration is a mixed-integer nonlinear optimisation problem, which minimises power loss without incurring new costs. The reconfiguration problem in the radial distribution system may be solved by applying the Stud krill herd method, which is suggested in this research for system active power loss minimization and voltage profile improvement. By taking into account various load circumstances, the suggested algorithm's performance is confirmed on IEEE standard test systems with 33 and 69 buses. It is shown how the suggested SKHA compares to current techniques for reconfiguring radial distribution networks. The results were compared with current techniques for reconfiguring radial distribution networks. Our findings show that the SKHA method significantly enhanced voltage profile, reduced power loss, and improved the overall solution quality. Specifically, SKHA was able to reduce real power loss by 33.85% and reactive power loss by 28.45% for the 33-bus system and 56.17% of real power loss and 43.85% of reactive power loss for the 69-bus system. © 2024 IEEE.

In this detailed study, four different fiber lengths (20, 30, 40, and 50 mm) of Borassus stalk leaf fibers were manually stacked into an unsaturated polyester resin matrix to create a composite material. They conducted detailed evaluations of mechanical properties while closely adhering to ASTM guidelines in their experimental methods. The outcomes unequivocally demonstrated a significant correlation between increased mechanical performance, such as tensile, flexural and impact strengths, and fiber length. Notably, composites with 50 mm fibers consistently performed better than others on all metrics, highlighting the critical influence of fiber length on these characteristics. These results highlight the significance of choosing the appropriate fiber length and offer insightful information for optimizing composite designs for certain applications. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

When the task of target detection implies the use of denoising methods, it is regarded as one of the most important in the field of image processing. Although, technological advancements have made it easier for objects to be tracked in space, it is currently among the most popular things. An identification of a multiframe marked point process model for the automatic abstraction of target system from sequences of images and the means employed in observing the movements of images has been provided. The other method employed in the frequency assessment is the normal non-harmonic analysis which aids in the improvement of noise reduction. The observed image data and different prior physical interactive requirements between the target occur under the subsequent frame are also taken into the consideration successfully. It handles scatterer scintillations as well as high noise from speckle for the final target sequence in the iterative optimization. It proposes a lengthy Mask Non-harmonic Analysis of point sequence to evaluate non-uniform regions of segmentation-related shapes. Lastly, after excluding scatterer in the image scenarios, evaluation is carried out for sequences of aircraft targets in images with various time differences and the scenes build up to the intended destination area. © 2024 IEEE.
