In the present work, an attempt is made to carry out a scientific comparison of three gait patterns namely One-phase, Two-phase, and Four-phase Discontinuous, which are under the category of Static and Periodic Gaits for a quadruped robot. In this paper, the authors have considered three degrees of freedom articulated leg mechanism for a quadruped robot. The kinematic analysis is implemented using MATLAB and simulations are performed in Simscape Multibody environment. The results are obtained for forward and lateral displacement, torso height, static stability margin, and longitudinal stability margin for different gaits considering the effect of Width-to-Length ratio of the body. Results of this study provide guidance on selecting the appropriate gait for different locomotion conditions.
With the increase in applications of FRP, disposal of waste has become a severe problem. So, incineration of the Fiber Reinforced Plastic (FRP) material waste is the alternate option to reduce the volume of waste. The incineration process produces small toxic dust particles. Double stage cyclone dust collector helps to remove small dust particles from flue gases. In this paper, different cyclone models are considered as 1D2D, 2D2D and 1D3D. Cyclone models are designed according to the functional requirement. Flow analysis is carried out in CFD software with parameters as velocity and barrel diameter of cyclone to study the dust collection efficiency.
Background: The escalating expansion of global telecom towers since the 1990s has led to an ageing infrastructure, with towers exceeding 30 years. Rust, a pervasive threat, jeopardizes structural integrity, posing risks of collapse and harm to riggers. Recognizing the importance of innovation in addressing this challenge, rust detection and tower maintenance patents play a crucial role in advancing the field. Objective: This paper focuses on detecting and evaluating rust levels on ageing telecom towers. Beyond addressing the immediate concerns, the objective includes exploring patented technologies in rust detection and prevention. The aim is to amalgamate innovative solutions into the algorithmic framework for automated rust detection, thereby enhancing the robustness and novelty of the proposed approach. Methods: The study involves a comprehensive literature review to identify patented technologies related to rust detection on structures like telecom towers. By integrating patented methods into the image processing code developed in Python, the algorithm gains an edge in accuracy and efficiency. The three-tier classification of rust severity aligns with patented preventative maintenance strategies, ensuring a holistic approach to tower care. Result: The amalgamation of patented technologies with the image processing code enhances the accuracy of rust detection on telecom towers. The results guide targeted treatments, informed by patented preventative maintenance strategies, including patented rust inhibitors, protective coatings, and corrosion-resistant materials. Conclusion: This paper introduces an innovative algorithm for rust detection and emphasizes the integration of patented technologies. Incorporating patented solutions into preventative maintenance strategies makes the approach more effective and technologically advanced. This holistic method not only benefits telecom companies in accident prevention and cost reduction but also positions the developed algorithm as a significant contribution to patented rust detection and tower maintenance technologies.
