To improve the efficiency of the electric vehicle (EV) drive systems and EV performance, the use of multi-speed transmissions and distributed drives has been studied extensively.In addition, to develop efficient and compact drive systems, new clutch solutions are needed.In this paper, we propose an in-wheel two-speed automatic mechanical transmissi
Abstract Background Protection of privacy data published in the health care field is an important research field.The Health Insurance Portability and Accountability Act (HIPAA) in the USA is the current legislation for privacy protection.However, the Institute of Medicine Committee on Health Research and the Privacy of Health Information recently c
The demand for new propeller designs has increased alongside the development of new technology, such as urban aircraft and large unmanned aerial vehicles.In order to experimentally identify the performance of a propeller, a wind tunnel that provides the operating flow is essential.However, in the case of a meter class or larger propeller, a large w
Postural stabilization during rapid and powerful hopping actions represents a significant challenge for legged robotics.One strategy utilized by humans to negotiate this difficulty is the robust activation of biarticular thigh muscles.Guided by this physiological principle, this study aims to enhance the postural stability of a hopping robot throug
