Concept, features and types of civil legal relations by K. S. Naumenko

“…Attention is drawn to the fact that civil legal relations are regulated not only by the rules of civil law, in particular, this is indicated by such a principle as freedom of contract in civil law. In other words, the content of civil law contracts may go beyond the legal relations provided for by the Civil Code of Ukraine. …”

Safeguarding accuracy for CT imaging with industrial robots: Efficient calibration methods for arbitrary trajectories by Anton Weiss, Simon Wittl, Gabriel Herl, Simon Zabler, Anna Trauth, Markus G. R. Sause

“…In order to be able to scan an arbitrary Region of Interest (ROI), regardless of the position, size and weight of the specimen, conventional industrial robots can be used as flexible 6 degrees of freedom (DOF) manipulators. For example in a twin robot computed tomography system, acquisition geometries with arbitrary tool poses can be realized. …”

Dynamic Behaviors Analysis of a Chaotic Circuit Based on a Novel Fractional-Order Generalized Memristor by Ningning Yang, Shucan Cheng, Chaojun Wu, Rong Jia, Chongxin Liu

“…The order, as an important parameter, can increase the degree of freedom of the system. With the change of the order and parameters, the circuit will exhibit abundant dynamic behaviors such as coexisting upper and lower limit cycle, single scroll chaotic attractors, and double scroll chaotic attractors under different initial conditions. …”

A Spatial Euler-Bernoulli Beam Element for Rigid-Flexible Coupling Dynamic Analysis of Flexible Structures by Zhigang Zhang, Zhaohui Qi, Zhigang Wu, Huiqing Fang

“…During the analysis, the global displacement and rotation vectors with six degrees of freedom are selected as the nodal coordinates. In addition, the “shear locking” problem is avoided successfully since the beam cross-sections are always perpendicular to the current neutral axes by employing a special coupled interpolation of the centroid position and the cross-section orientation. …”
