| Contrastive Texture Metric Learning: An Attention-Guided Siamese Model for Fabric Inspection | ||||||
In smart manufacturing systems, it is crucial to diagnose defects as products pass along conveyor belts using automated computer vision systems. Compared to traditional manual defect diagnosis methods, this approach reduces time loss, high costs, and operator errors. This study proposes a fast Siamese network supported by contrastive learning and attention mechanisms for the detection and classification of fabric defects. A Channel Attention module is integrated during the feature extraction phase to ensure the network focuses on key regions. Thanks to the Siamese structure, samples belonging to the same class are brought closer together in the feature space, while different classes are distanced from each other............

| Vibroacoustic Response of a Finite Double-Composite Plate Filled with an Air Cavity in Thermal Environment | ||||||
This work develops an analytical framework based on classical laminated plate theory to characterize the vibroacoustic behavior of finite, simply supported, orthotropic double-panel composite structures enclosing an air cavity. The coupled system is subjected to simultaneous thermal fields and harmonic wave excitations. By leveraging the modal decomposition technique, the governing equations are solved using a double Fourier series approach to map the acoustic insulation metrics of the panel........

| Design and Development of Musical Toy using Shape Display Board | ||||||
The project focuses on the Design and Development of Musical Toy using Shape Display Board. The design of the product aims to provide a musical toy for children between the ages of 3 – 5 Years to promote Cognitive Development. Factors like safety of the child, ease of use are also considered while designing the product.
The Aim and objective of the design of the musical toy is to incorporate suggestions and improvements of the musical toy by understanding the problems faced by the child and the parents in the existing musical toys. The process of designing incorporates multiple steps which include literature study, material study, case study, location study, user study, market study, patent study & working of the toy to obtain the final product..........

| Attenuation of Stress Disturbances Around Nozzles in Pressure Vessels | ||||||
Nozzles installed in pressure vessels introduce local geometric discontinuities that disturb the nominal membrane stress distribution of the vessel shell. These disturbances arise from the shell opening, nozzle stiffness, reinforcement details, weld attachments, and externally applied loads transmitted through connected piping. Although high localized stresses may develop in the vicinity of the nozzle-to-shell junction, classical shell theory predicts that their influence diminishes rapidly with increasing distance from the discontinuity. This paper examines the attenuation of nozzle-induced stress disturbances in both cylindrical and spherical pressure-vessel shells, including unreinforced and pad-reinforced nozzle configurations..........
