Illuminating the dark conformational space of macrocycles using dominant rotors
Nature Chemistry, 2021Three-dimensional conformation is the primary determinant of molecular properties. The thermal energy available at room temperature typically equilibrates the accessible conformational states. Here, we introduce a method for isolating unique and previously understudied conformations of macrocycles.

Time-Space Spectral Method for Rotor–Rotor/Stator–Stator Interactions
Journal of Turbomachinery, 2019AbstractThe paper presents a time-space spectral method for an efficient analysis of rotor–rotor/stator–stator interactions in the framework of the time spectral form harmonic balance method. The method treats time and space harmonics in a coherent way and allows for easy choice of time and passage through the introduction of pseudo-shaft frequency and

Induction Motor Rotor Condition Monitoring Using Rotor Voltage Space Vector
2019 Chinese Automation Congress (CAC), 2019High-speed train is developing very fast. As an important part of the train, motor failures can cause many problems. In order to solve the problems, it is important to get the precise motor condition in time. Over the past several decades, many researches on motor faults diagnosis, have been presented.

REMARKS ON SYMMETRIES OF GENERALIZED ROTOR SPACE
International Journal of Modern Physics E, 2004We propose methods of analysis of the symmetries of the rotor space. A few examples of the point symmetries and their consequences for the state space of the quantum rotors are shortly considered.

State Estimation for International Space Station Centrifuge Rotor
AIAA Guidance, Navigation, and Control Conference and Exhibit, 2005This paper describes the design of a state estimator to generate absolute centrifuge rotor state information from relative measurements, between the rotor and the International Space Station structure, in the absence of disturba nce input knowledge. A Kalman filter is designed for a plant model augmented with internal disturbance states.
