Maximising somersault rotation in tumbling.
Performing complex somersaulting skills during the flight phase of tumbling requires the generation of linear and angular momenta during the approach and takeoff phases. This paper investigates how approach characteristics and takeoff technique affect performance with a view to maximising somersault rotation in tumbling. A five-segment planar simulation model, customised to an elite gymnast, wa...
متن کاملTumbling and technicolor theory.
The extended technicolor theory is a candidate of the physics beyond the standard model. To explain the mass hierarchy of the quarks and leptons, the extended technicolor gauge symmetry must hierarchically break to the technicolor gauge symmetry. Tumbling gauge theory is considered as a candidate of the dynamics of such hierarchical symmetry breaking, since the sequential self-breaking of the g...
متن کاملA Variable Selection Method for Pulverizing Capability Prediction of Tumbling Mill Based on Improved Hybrid Genetic Algorithm
Tumbling mill of thermal power plant, grinding the raw coal for the boiler, has high energy consumption, and pulverizing capability is usually used for representing the efficiency of tumbling mill. In the paper, a variable selection method for pulverizing capability prediction of tumbling mill based on improved hybrid genetic algorithm is proposed. Based on the tradition GA, the proposed method...
متن کاملStrip/Foil Rolling Mill Stochastic Excitation Model and Its Stability
Based on the stochastic rolling force data from aluminum hot strip tandem mill, the ARMA time series model and the stochastic excitation power spectral density (PSD) model are established, and the stochastic rolling forces excitation model is established by utilizing Levenberg-Marquardt combined with generalized global planning algorithm. A two dimensional stochastic nonlinear dynamical model o...
متن کاملTumbling Political Theory
Blogging in the classroom is not a new idea, but my students have tended to view the blogging assignment negatively, as a homework assignment that simply needed to be done each week and then forgotten until the next time they were required to visit the blog. With that in mind, I decided to employ a very different method of educational blogging—using the Tumblr platform—in which each student wou...
