Artificial Neural Network for Vibration Frequency Measurement Using Kinect V2 by Jiantao Liu, Xiaoxiang Yang

“…Furthermore, the optical measurement method can provide full-field measurement results of the target object without affecting the physical properties of the measurement target, such as stiffness, mass, or damping. The advent of consumer grade depth cameras, such as the Microsoft Kinect, Intel RealSence, and ASUS Xtion, has attracted significant research attention owing to their availability and robustness in sampling depth information. …”

Dynamic Characteristics of Coral Sand in the Condition of Particle Breakage by Hui Long, Ke Zhuang, Bo Deng, Jianlin Jiao, Junjie Zuo, Enlu You

“…The results show that with the degree of coral sand particle breakage increases, the maximum dynamic shear modulus of coral sand first increases and then decreases, and the minimum damping ratio also shows a similar trend. In addition, based on Hardin’s theory of the relative breakage, this study proposes a new modified relative breakage Br′ for describing particle breakage and establishes a relationship between the maximum dynamic shear modulus and the modified relative breakage Br′.…”

Review on Mathematical and Mechanical Models of the Vocal Cord by L. Cveticanin

“…The model is not only extended into three, five, and more mass systems, systems with time variable parameters and three-dimensional systems, but also simplified into one-mass system with coupled two-direction deflection and damping functions. The corresponding mathematical models are the systems of coupled second-order differential equations which describe the vibrations of the symmetric and asymmetric vocal folds. …”
