Design and development of easy operated and cost-effective advanced fertilizer spraying mechanism
Abstract: Agriculture is very labour-intensive and requires efficiency and productivity to minimise cost and maximise yield. Manual application of fertilizer was one of the greatest challenges that a farmer faces, and it is a very time-consuming, physically demanding, and labor-intensive task. The traditional backpack sprayers have high burden on the on-farm labor and with their non-uniform application, there are inefficiencies and potential crop injury. In response, it is proposed to develop …

Design and Development of Twin booster - A Sustainable Health Solution
Abstract: During the revolution in eco-friendly technologies, cycling has emerged as one of the most dependable and sustainable modes of transportation. Rising fuel prices, increasing traffic congestion, and the growing threat of global warming have challenged researchers and engineers to develop environmentally friendly alternatives for short-distance travel. Among the available solutions, bicycles remain one of the simplest, most affordable, and non-polluting transportation systems. In addition to mobility, bicycles have also gained …

A Review on the Design of Vortex Flow Generator to Optimize Heat Transfer Enhancement in a Straight Tube
Abstract: This research focuses on the design and evaluation of a vortex flow generator (VFG) for improving heat transfer performance in a straight circular tube. Vortex generators create longitudinal and swirling secondary flows inside the tube, which enhance fluid mixing, disturb the thermal boundary layer, and increase convective heat transfer. Vortex flow generators placed inside straight tubes are widely used to improve heat transfer performance in thermal systems. These devices create …

A Review on Design and Flow Analysis of Quadcopter Propellers
Abstract: The quadcopter is a complex system in which propeller blades, aerodynamics, and structural behavior are tightly interlinked. Changing a small detail, such as blade angle or material, can significantly affect performance parameters like thrust and efficiency, as well as the drone's vibrations and stability in flight. Because quadcopters typically operate at Reynolds numbers between roughly 20,000 and 150,000, propeller theories developed for full-scale aircraft often fail to translate directly, making …

Impact of Thermal Image Preprocessing Methods on a ResNet50 Model Baseline Performance for Ball Bearing Fault Diagnosis
Abstract: Ball bearings are an important part for the operational rotating machinery. To prevent it from failing, traditional engineering uses many methods. One of these is infrared thermography (IRT). IRT is a useful tool that helps monitor the situation without physical contact. But in the current world, various fields use artificial intelligence to do it more accurately & for fast detection. Deep learning models play an important role in fault detection …
