This paper implements GRAFCET based model for processing station in modular production system. The GRAFCET for the sequence of operation in processing station was implemented and equations were extracted from the GRAFCET followed by converting the equation into equivalent ladder logic program. The implementation of the ladder logic program was performed using Codesys 2.3V software and hardware used to check the reliability of the program was modular production system - Processing station. The proposed GRAFCET based model was found to be reliable, efficient and accurate in performing the control sequence in the processing station. In future the GRAFCET will be implemented in the form of sequential flow chart instead of converting it into ladder logic programming which is time consuming. © 2023 IEEE.

Industrial 4.0 is revolutionizing the world including robotics, nanotechnologies etc., Still detecting defects on parts has a significant challenge to solve. The manufacturing factories and distribution centres have complex technologies for inspection of the products and packaging process. Especially the food and clothing industries have to deeply investigate the defects. Conventional inspection systems implement physical inspection techniques to find defects in the product which may have a chance to affect the final product. In some test methods only relatively non-porous surfaces can be inspected and in some cases, this can be affected by variations in magnetic permeability. A well-achieved visual inspection provides a reduction in the amount of repairs and overcomes the above-mentioned problems in the inspection system. By simply presenting the inspection system with several model images, deep learning enables it to learn to detect surface anomalies. The device which works on the concept of Deep Learning based image analysis for factory automation is our proposed theme. To train the machine, sample image sets are given. This can be made customized as data sheets are given to the software. Hence, the proposed system can be customizable according to the product dimensions. © 2023 IEEE.

Combined heat and power economic load dispatch is an optimization problem in power systems to schedule the generation output satisfying the demand with the most economical operational cost. This paper presents a class topper optimization technique to solve the highly non-linear combined heat and power economic dispatch (CHPED) problems. The class topper optimization (CTO) algorithm process identifies and implements strategies to enhance students’ learning performance to maximize their potential by improving knowledge. Here, the inter-dependency of power and heat production in CHPED problems increases the complexity and non-convexity in their nature. The main objective is to minimize the total operational fuel cost for power and heat generation units while fulfilling the demand and practical constraints, e.g., valve-point effects, prohibited operating zones (POZs) and transmission loss. For illustrative purposes, class topper optimization is applied to two case studies of the CHPED problem with and without losses to validate effectiveness and demonstrate superiority compared to well-known previously published existing techniques for obtaining desirable practical solutions. ©2024 IEEE.

Image fusion involves extracting and combining the most meaningful information from images captured by different sensors, aiming to create a single image beneficial for further applications. The development of deep learning has significantly advanced image fusion, with neural networks' powerful feature extraction and reconstruction capabilities broadening the prospects for fused images. This study introduces the Adaptive Variational Autoencoder Image Fusion Network (AVAFN), enhancing the Variational Autoencoder (VAE) architecture by incorporating additional convolutional, ReLU, and Dropout layers to improve feature extraction and prevent overfitting. AVAFN introduces a novel loss function that considers global contrast, feature intensity, and structural texture, reducing feature and contrast loss during fusion and preserving detail texture in line with human visual perception. The importance of loss function weights is evident in AVAFN's Adaptive Loss Assignment Method, which adjusts loss weights based on the different feature information of input images, analyzes various depth features, and obtains optimal fusion outcomes. Experimental results reveal that AVAFN excels in multi-modal and multi-exposure image fusion, achieving scene-appropriate fusion results through color channel transformation and effectively extracting depth features in multi-input image fusion tasks through the Concatenation function. These results, confirmed by comparisons with popular fusion methods across three image databases, demonstrate AVAFN's superiority in subjective visual perception and objective fusion metrics. The experiments validate AVAFN's applicability to various image fusion tasks, achieving the desired fusion outcomes even in low-quality images and showcasing its potential in the image fusion domain. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.

This paper proposed a population-based meta-heuristic algorithm, an adaptive chaotic class topper optimization (AC-CTO) algorithm for solving combined heat and power economic dispatch (CHPED) problems. The proposed algorithm is an improved version of classical class topper optimization, where the desirable practical solutions are obtained based on the learning process, improving the students' knowledge. Here, the complexity of combined heat and power is increased due to their mutual interdependence and is non-linear in nature. The main goal is to achieve the minimum fuel cost while satisfying demand, considering the practical system constraints such as valve-point effects, prohibited operating zones, and transmission loss. To evaluate the performance, the proposed algorithm is tested for two case studies, one without system losses - 4 unit system and the other with system losses - 7 unit system. The results of the study indicate that AC-CTO algorithms outperform popular optimization methods to solve the CHPED problems and obtain the lowest fuel cost. © 2024 IEEE.

The paper reports how welding current and electrode polarity affect on weld bead geometry and shape relationships in a gravity-assisted SMAW process. An air-hardening MFH 350 electrode was used. Various weld bead geometry parameters, i.e., bead height, bead penetration, bead width, and shape relationships, i.e., weld reinforcement form factor, weld penetration shape factor, percent dilution, and linear heat input, have been recorded and computed. A gravity-assisted mechanized setup, fabricated in the welding research laboratory was used for continuous mechanized contact welding. The mechanization fully eliminated the effect of the welder’s skill on the melting rate and the BG and SR. The melting rate and hence the welding speed of the bead on plate deposition were varied by varying the welding current. The welding current was varied from 120 to 180 amperes. The whole experiment was conducted with DCEN and DCEP. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
