Muscle fiber excitation system

2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2016
Persons unable to exercise due to old age, immobility or medical condition may develop low bone density, decline in muscle contraction, blood pooling or clot. Due to musculoskeletal fragility caution is required in bone and muscle strengthening. Similarly, caution is required to use anticoagulant drug to prevent blood clot due to side effect, and ...

Amplidyne main exciter excitation system

Transactions of the American Institute of Electrical Engineers. Part III: Power Apparatus and Systems, 1961
The amplidyne exciter combines the basic characteristics of a conventional commutator-type exciter with the buckboost amplidyne features presently used for voltage regulators. The power required to control this exciter is small, permitting new types of voltage regulators to be used and additional, previously impossible exciter functions to be performed.

Generator Excitation Loss Detection on Various Excitation Systems and Excitation System Failures

2020
Generating steadiness of synchronous generator is highly dependent on their exciter as the direct current from excitation system sustains stator and rotor windings magnetically coupled. But generator loss of excitation weakens stator and rotor coupling which result in mechanical and electrical power imbalance and rotor speed rise beyond synchronous ...

Double excitations in finite systems

The Journal of Chemical Physics, 2009
Time-dependent density-functional theory (TDDFT) is widely used in the study of linear response properties of finite systems. However, there are difficulties in properly describing excited states, which have double- and higher-excitation characters, which are particularly important in molecules with an open-shell ground state.
