This paper presents a theoretical study of the dynamic behaviour wind turbine consisting rotor, speed increaser with fixed axes, and counter-rotating electric generator, operating in variable conditions. In first part, analytical model mechanical system is elaborated based on equations associated component rigid bodies linear characteristics direct current (DC) generator rotor. The proposes met...

The Potential Energy Surface PES of (H2)2 dimer has been investigated, using five simple rigid rotor models. These models are called: head to head, symmetric side to side, L , steplike and T model. All calculations were done at two levels of ab initio  methods: MP2(Full) and QCISD (T,Full) using cc-pVTZ basis set at singlet state of spin multiplicity. The results of scanning PES were then fitte...

Exact numerical diagonalization of the Bohr Hamiltonian by SU(1, 1) × SO(5) methods is used to obtain detailed quantitative predictions for single-phonon and multi-phonon excitations in well-deformed rotor nuclei. Dynamical γ deformation is found to significantly influence the predictions through its coupling to the rotational motion. Basic signatures for the onset of rigid triaxial deformation...

We introduce a Hartree-Fock-Bogoliubov mean-field approach to treat the problem of proton emission from a deformed nucleus. By substituting a rigid rotor in a particle-rotor-model with a mean-field we obtain a better description of experimental data in Ho. The approach also elucidates the softening of kinematic coupling between particle and collective rotation, the Coriolis attenuation problem....

We analyze the nature of the rotational energy level structure of the OCS-He and OCS-H2 complexes with a comparison of exact calculations to several different dynamical approximations. We compare with the clamped coordinate quasiadiabatic approximation that introduces an effective potential for each asymmetric rotor level, with an effective rotation Hamiltonian constructed from ground state ave...
