Pedagogic Use of Commercial Feature Film in Christ University Deanery of Humanities and Social Sciences

Pushpendra Kumar Aasita Bali

This thesis discusses the use of commercial feature film as a pedagogical tool in the classrooms within the Deanery of Humanities and Social Sciences of Christ University. It investigates the purpose of using films as pedagogy in higher education and the reasons behind its popularity among both teachers and students. Triangulation method was used for gathering data combining qualitative and quantitative methods such as pretesting posttesting, survey and in depth interviews. Information was gathered by using interview schedule and online questionnaires from teachers and students of the Deanery of Humanities and Social Sciences to analyze the plausible impact of feature films as pedagogy in subjects taught. The findings suggest that films are popular pedagogical tool and are effective if used along with discussions post screening.

Microscopic traffic dynamics and platoon control based on bond graph modeling

Pushpendra Kumar Rochdi Merzouki Belkacem Ould Bouamama Hafid Haffaf

Modeling of traffic dynamic is important for the good traffic management which leads to sustainable transport. Traffic models are classified based on level of details they provide as microscopic models and macroscopic models. A microscopic model of traffic flow describes the behavior of individual vehicle in response to motion of the vehicle preceding it, while, a macroscopic model describes the behavior of the traffic as a whole, but the behavior of individual vehicle is not described. In the present work, we develop a microscopic model of car-following behavior of the vehicles and introduce the sub-microscopic model of traffic, in which the dynamic model of each vehicle is developed, which is not considered in most of the existing microscopic models. Then, a model based control strategy is proposed for the local control of the platoon of the intelligent autonomous vehicles (IAVs). This model based control strategy analytically provides the calculation of necessary effort for the follower IAV to maintain the safe inter-distance with the leader IAV.

Experimental study on a bending type soft pneumatic actuator for minimizing the ballooning using chamber-reinforcement

Heliyon (2023)

Narendra Gariya Pushpendra Kumar Tej Singh

Soft robotics is an emerging area of research due to its safe interaction with humans; it also has exciting applications, such as wearable soft medical devices for rehabilitation, prosthetics, etc. Soft robots require soft actuators for performing desired movements, including bending, expansion, contraction, and twisting. This work focuses on bending-type multi-chambered extra-soft actuators actuated by pneumatic pressure. The corrugated design of a multi-chambered soft pneumatic actuator (SPA) is analyzed experimentally to observe the radial, longitudinal, and lateral expansions of different chambers, i.e., ballooning of the chambers under the application of air pressure. From the experimental study, it is observed that the ballooning mainly occurs at the free end of the actuator in a cantilever-type boundary condition, which could not be demonstrated by the computational solution using the finite element analysis (FEA). Moreover, it is observed that the effect of ballooning also disturbs the constant curvature profile of SPA. Therefore, a chamber-reinforcement solution is provided for minimizing the ballooning and ensuring the uniform bending of a SPA.

Dynamic Analysis of a Quarter Car Model Moving Over a Gaussian Bump

Journal of Graphic Era University (2020)

Vipul Paliwal Ritvik Dobriyal Pushpendra Kumar

Suspensions ystems have always been animportant part of consideration in automobile considering the ride comfort and passenger safety. A modern vehicle utilizes advanced suspension systems and therefore various studies regarding quarter car suspension analysis have been done. The present workon quarter car model passing over a Gaussian bump is carried out to investigate the effect of spring stiffness on the ride comfort considering a speed range of 10 km/hr –20 km/hr. The equations of the quarter car system are solved by MATLAB and the behavior of the system with different spring stiffness is analyzed with respect to its effect on sprung mass displacement and Root Mean Square (RMS) value of the sprung mass displacement

Bond Graph Model-Based Control of the Quadcopter Dynamics

Djihad Matouk Faraz Ahmad Pushpendra Kumar Rochdi Merzouki Manarshhjot Singh

This paper presents graphical modeling and control of the quadcopter dynamics. A quadcopter is an under-actuated system with nonlinear dynamics. For stabilization of such complex system, it is necessary to have a nonlinear control. Therefore, a model-based control is developed for the altitude (height) and attitude (roll, pitch, and yaw) control of the quadcopter dynamics. The dynamic model of quadcopter is developed using a power-based graphical modeling tool, called bond graph. Subsequently, the bond graph model is used to develop altitude and attitude control of the quadcopter. Finally, the developed algorithm is validated through simulation.

Barrel Effect of High-Rate Capability Determined by Anode Electrode for Lithium-Ion Battery

Hai Ming Mengyang Liu Songtong Zhang Xiayu Zhu Pushpendra Kumar

To date, charging time remains a critical issue that impedes the widespread application of lithium-ion batteries (LIBs). A comprehensive understanding of the attenuation mechanism of LIBs at high (dis)charging rates is essential for clarifying application strategies for extreme operating conditions and environments, thereby enhancing battery control, and guiding the design of advanced batteries with superior rate capability. In line with this focus, particular commercial LiNi0.5Co0.2Mn0.3O2/graphite batteries are explored under various high-rate (dis)charging procedures, alongside the investigation of the impact of constant voltage steps on battery performance. This exploration reveals that capacity degradation occurs in three stages, and the rate of capacity decay is directly proportional to the (dis)charging rate. Furthermore, the in-situ temperature and stress of the battery during cycling, primarily caused by side reactions, are monitored to confirm the thermal effects and stress variations under high-rate conditions. By characterizing the morphology and composition of the electrode surface after post-mortem analysis, the "barrel effect" of high-rate capability determined by the anode electrode for LIBs is proposed. This research aims to establish optimal guidelines for designing batteries with excellent high-rate properties and to provide solutions for improving the safety and reliability of batteries applied in high-rate conditions.

Experimental Study of a Soft Pneumatic Actuator for the Application of Robotic Gripper

Narendra Gariya Pushpendra Kumar Mohit Makkar

Soft bending actuators are being used in many applications such as in soft robotics and medical devices due to their compliant behavior and safe interaction. These soft actuators are mainly actuated by pneumatic pressure because of cleaner and safer operations while dealing with delicate objects and human. A soft pneumatic actuator (SPA) with multi-chambered structure is more efficient than a single chamber SPA. In this paper, a multi-chambered SPA is designed and studied experimentally. The designed SPA is fabricated using two different soft hyperelastic materials namely, Ecoflex-0030 and Ecoflex-0050. The fabrication process utilized the 3D printing and casting techniques. From the experimental studies, it is found that the SPA fabricated using Ecoflex-0050 shows more uniform bending. Therefore, this SPA is further utilized for developing a soft pneumatic gripper for the robotic application. Three fingers of Ecoflex-0050 SPA are used for the soft robotic gripper, which is tested experimentally for handling delicate objects. From the experiments, it has been observed that the developed SPA is able to grasp and hold objects of different shapes and sizes with a load carrying capacity of approximately 650 gm.
