Reducing the Standstill Spacing and Duration of Safe Braking Control in Vehicle Platoons With Delays

IEEE Access, 2020
Braking control, especially in an emergency, is a key technology that is needed to ensure safety in vehicle platoons. However, delays in vehicle platoons can severely affect braking control.

p21WAF1/CIP1 Acts as a Brake in Osteoblast Differentiation

Journal of Bone and Mineral Research, 2003
Abstract Continuous fibroblast growth factor signaling inhibits the differentiation of primary osteoblasts and osteoblastic cell lines. We studied the expression of several cell cycle regulatory molecules in response to fibroblast growth factor, and found that fibroblast growth factor strongly upregulates the expression of p21WAF1/CIP1 ...

Impact of large-scale photovoltaic-energy storage power generation system access on differential protection of main transformer under symmetrical faults

Frontiers in Energy Research, 2023
The low voltage ride-through (LVRT) requirements demand large-scale photovoltaic (PV) power generation system remain connected to the grid during faults. It results in considerable impact on the characteristics of fault current.

Magnetic braking and damping of differential rotation in massive stars

Physical Review D, 2019
Fragmentation of highly differentially rotating massive stars that undergo collapse has been suggested as a possible channel for binary black hole formation. Such a scenario could explain the formation of the new population of massive black holes detected by the LIGO/VIRGO gravitational wave laser interferometers.

Adaptive Rollover Prevention for Automotive Vehicles with Differential Braking [PDF]

IFAC Proceedings Volumes, 2008
Abstract In this paper we present an adaptive controller implementation based on the multiple models, switching, and tuning (MMST) paradigm [Narendra and Balakrishnan, 1994, 1997] for preventing un–tripped rollover in automotive vehicles. Our approach relies on differential-braking to keep the value of the Load Transfer Ratio ( LTR ) below a ...

Study on Differential Regenerative Braking Torque Control to Increase the Stability of the Small Electric Vehicle with Four In-Wheel Motors

MATEC Web of Conferences, 2017
Based on the advantages of the electric motor such as fast and precise torque response, the performance of the electric vehicle (EV) can be improved. During braking or driving on the cornering, the vehicle will over steer or under steer if a car turns by
