Batteryless Solutions refer to the elimination of the use of primary non-rechargeable batteries andreplacing them with any kind of sustainable alternatives that combines circuits with long lasting rechargeable batteries or with alternative energy storage systems that provide a less polluting and a much eco-friendlier alternative. There is no specific limit for batteryless solutions and it just involves innovation and improvisation on existing rechargeable battery technologies and alternative energy storage systems so that they are long lasting, use fewer toxic chemicals as raw material, have good energy densities and are compatible with renewable energy sources like solar and wind and should also offer compatibility to hybridization and combination with other sources and they should have the necessary protection features integrated for smootherrunning. This mini project aims at building two prototypes which can interface Lithium-Ion batteries and Supercapacitors with power electronics and other charging circuits so as to act as a source of energy.

In the Jidong region of the JS Basin, deep shale gas horizontal wells at depths over 3,500 meters have experienced casing deformation issues during staged fracturing operations. This problem has significantly constrained the development efficiency of deep shale gas in this area. A multi-factor analysis was conducted on typical deep shale gas horizontal wells in the Jidong block, further clarifying the main characteristics and causes of casing deformation. Physical simulation analysis of casing deformation during shale gas well fracturing revealed the mechanism behind the casing deformation, providing a theoretical basis for prediction and prevention. It was found that casing deformation in deep horizontal wells in the Jidong block is primarily influenced by geological and engineering factors. during fracturing, large volumes of fracturing fluid are injected into the formation, and after connecting with natural fractures, the formation exerts shear stress on the wellbore, leading to casing damage. The results show that in the presence of natural fractures, varying stress conditions can alter the direction of hydraulic fracture propagation. Under strike-slip fault stress conditions, hydraulic fractures are prone to deflection, causing sheardeformation. The stress state and the inclination of natural fractures are the primary factors influencing the slip and movement of the fracture surfaces. Under strike-slip fault stress conditions, natural fractures are more likely to experience slip and shear, leading to casing deformation. The closer the natural fractures are to the Coulomb failure surface, the more likely they are to slip anddisplace, causing casing deformation. Further analysis of field wells confirmed the contributing factors to casing deformation, providing technical guidance and experience for the prediction and prevention of casing deformation.

Laborsaving is a major issue in production. In an automotive production line, a yard that is used as a temporary storage for vehicles before shipping. The vehicle-loading robot that operates autonomously has been proposed to automate the alignment of vehicles in the yard instead of human driving. In this study, the dynamic wireless power transfer system that includes the structure of the roadside for the vehicle-loadedrobot is proposed. It is proven that the transmitter coil has enough durability for the load of the robot weight using simulation and actual measurement. It is also shown that the reinforcement bars of the road structure cause considerable eddy current loss even with stainless steel. This is similar to loss by coil resistance. This system achieves a 1.8 kW dynamic wireless power transfer with an automated coil detection system and a frequency control system, under factory conditions. 2022 The Institute of Electrical Engineers of Japan.

To guarantee extended battery life and sustainability, there is an increasing need to address power consumption concerns as IoT devices increase in various applications. AI and ML techniques have shown promise in reducing power usage in automated Internet of Things devices. To improve power utilization in IoTdevices, this study investigates the application of AI and ML approaches to various tactics, including energy-efficient scheduling, adaptive power management, and intelligent sensordata processing. IoT devices may adaptively modify their power consumption using AI and ML algorithms depending on contextual elements like user behavior, ambient circumstances, and workload needs. Predictive analytics powered by AI can also foresee future power needs and optimize energy use before they arise. The usefulness and possible drawbacks of AI and ML-based power-saving approaches for automated IoT devices are reviewed in this study, along with previous research on the subject. Therefore, intelligent power management that improves energy economy without sacrificing performance or user experience is made possible by incorporating AI and ML techniques into IoT device design. By offering insights into cutting-edge powerreduction techniques made possible by dL and ML, this article adds to the continuing conversation on the growth of the Internet of Things in a sustainable manner.
