The design of homologically deforming cyclically symmetric structures
… deforming telescope structure is a purely cyclically symmetric one. However, for millimetre wave telescopes this form of structure presents practical difficulties, so a region of structural non-cyclic symmetry is introduced. To enable the complete telescope structure to be analysed yet …

Modal Analysis of General Cyclically Symmetric Systems with Applications to Multi-Stage Structures
… investigates the modal properties of general cyclically symmetric systems and the multi-stage systems with cyclically symmetric stages. The work generalizes the modal properties of engineering applications, such as planetary gears, centrifugal pendulum vibration absorber (CPVA) systems, …

Análise elástica bidimensional de problemas com simetria cíclica pelo método dos elementos de contorno
… Element Method is applied to the solution of cyclic symmetry plane problems. Initially, the basic concepts and the general formulation of the method are presented. The boundary of the body is discretized in quadratic continuous elements, over which the displacements and tractions are assumed …

Mean Field Analysis of Generalized Cyclic Competitions
… of high-dimensional models that possess a cyclic symmetry in the network that specifies their stochastic dynamics at the microscopic level. Our analysis is carried out in a manner that can be readily adapted for the mean field analysis of further generalized models that possess this …

Reduced-order aerodynamic models for aeroelastic control of turbomachines
… the models can be applied to problems which lack cyclic symmetry. Although most aeroelastic analyses assume each blade to be identical, in practice variations in blade shape and structural properties exist due to manufacturing limitations and engine wear. These blade to blade variations, known as …

Helical reconstruction of Mycobacterium smegmatis Mycothiol S-conjugate amidase filaments
… filaments, which showed helical order. Helical symmetry was estimated using power spectra from single filaments. The number of potential symmetry solutions was reduced using phase information from Fourier transforms of single filaments. Three possible solutions to the helical symmetry were …

Dynamics of High-Speed Planetary Gears with a Deformable Ring
… gears have structured modal properties due to cyclic symmetry, but these modal properties are different for spinning systems with gyroscopic effects and stationary systems without gyroscopic effects. Vibration modes for stationary systems are real-valued standing wave modes, while those for …
