This method utilizes the angular momentum of the base, without causing its nutation, which occurs unless the final attitude of the base is the same as the initial one. Although Kepler was forced to abandon them in favour of ellipses as a method of describing the structure of the solar system, he retained his fascination for these almost perfect shapes. Although symmetry was studied by the French mathematician Evariste Galois in the early 1830s and by the German Emmy Noether around 1916, its importance was not fully understood until the development of group theory later in the 20th century.

The algorithm develops within and through each MDCT slice, until the user stops its evolution. Its range of applications in daily practice is growing exponentially, although they mainly focus on spine, pelvis, and lower-limb imaging. Specifically, we are interested in: devising control methods to drive the shifting masses, evaluating the disturbance rejection capabilities under realistic conditions, and evaluating the implementation feasibility of the whole shifting masses concept. The images are taken in the standing position, allowing the spine and lower limbs to be examined under normal weight-bearing conditions. A well-trained operator can perform 3D reconstruction of the skeletal envelope, and about 100 clinical parameters for the spine and lower limbs are automatically calculated. The RS-422/423 ANSI standards were created as industrial serial bus standards, and have proved vastly superior performance than the previous RS-232 due to the use of lower voltages and differential signaling for higher bit rates.
Like Kepler they have looked to their stock of tools for expressing harmonious or symmetrical relationships for an answer. The regular solids used by Plato and Kepler to represent the elements and the planetary orbits are absolutely symmetrical. To create a concrete model of the planets’ orbits, which were puzzling astronomers, Kepler used geometric shapes that he knew were symmetrical, thereby expressing his vision of cosmic harmony. In his De Niva Sexangula (The Six-Cornered Snowflake) of 1610 he used five- and six-pointed star shapes to represent the structure of snow crystals, thereby laying the foundation of modern crystallography. Here, MTAR is the Target’s internal momentum, and τTAR is the applied torque in the Target’s frame (which could include external disturbance torques).
In his derivation, the reaction forces and torques at the joints are not explicit in the formulation and aims to expose the body axes so that it is convenient to incorporate control laws, internal forces and other disturbance forces into the model that would not be straightforward to introduce using a Lagrangian formulation. A spacecraft-manipulator system is here defined to be rotation-flying when the DOF at the manipulator joints are actively controlled by joint motor torques and the three DOF of orientation of the base-spacecraft are actively controlled by external torques only. The above analysis showed that in the case of the control of FFSMS with NZAM, the application of controllers, which ignore the system initial angular momentum (e.g., PD control law) results in final non-zero errors both in joint and Cartesian space. The calculation of this expression requires the joint-angle derivatives of the joint and link transformation matrices JTJi and JTLi, as well as the joint angle derivatives of the linear and angular motion Jacobians.
