“…Where the Dialect classification is a solution which can characterize speaker traits and help in the development/selection of dynamic lexicons by selecting alternative pronunciations, generate pronunciation modeling via dialect adaptation, or train and adapt dialect dependent acoustic models. Dialect knowledge is also helpful for data mining and spoken document retrieval [5].…”

Automatic Dialect classification (ADC) is represented important new part in automatic speech recognition (ASR). In this paper an automatic Dialect classification to independent system for Arabic languages is presented. The speakers of this system are from some Arabic countries: Egyptian, Iraq, Levantine and Kuwait, where each speaker speaks clip from the dialect of his country. The MFCC is adopted here to extract the important features from the speech signal. In the recognition task the Linear discriminant analyses (LDA) and Dynamic time warping (DTW) are used in classification stage. The LDA and DTW methods are efficient tools for the classification problems with many variations in speech signal. During the testing process, the LDA and DTW was given efficient results in identifying the classes dialect speaker, but the success rate her for DTW is somewhat better compared to LDA .

“…The PNC-CSM method is proposed to treat properly the pairing correlations and blocking effects. It has been applied successfully for describing the properties of normal deformed nuclei in A ∼ 170 mass region [47][48][49][50][51][52], superdeformed nuclei in A ∼ 150, 190 mass region [53][54][55][56][57][58][59], high-K isomeric states in the rare-earth and actinide mass region [60][61][62][63][64][65][66] and recently in the heaviest actinides and light superheavy nuclei around Z ∼ 100 region [23,24,39,67]. In contrast to the conventional Bardeen-Cooper-Schrieffer (BCS) or HFB approach, the Hamiltonian is diagonalized directly in a truncated Fock space in the PNC method [68,69].…”

Experimentally observed ground state band based on the 1/2 − [521] Nilsson state and the first exited band based on the 7/2 − [514] Nilsson state of the odd-Z nucleus 255 Lr are studied by the cranked shell model (CSM) with the paring correlations treated by the particle-number-conserving (PNC) method. This is the first time the detailed theoretical investigations are performed on these rotational bands. Both experimental kinematic and dynamic moments of inertia (J (1) and J (2) ) versus rotational frequency are reproduced quite well by the PNC-CSM calculations. By comparing the theoretical kinematic moment of inertia J (1) with the experimental ones extracted from different spin assignments, the spin 17/2 − → 13/2 − is assigned to the lowest-lying 196.6(5) keV transition of the 1/2 − [521] band, and 15/2 − → 11/2 − to the 189(1) keV transition of the 7/2 − [514] band, respectively. The proton N = 7 major shell is included in the calculations. The intruder of the high−j low−Ω 1j 15/2 (1/2 − [770]) orbital at the high spin leads to band-crossings at ω ≈ 0.20 ( ω ≈ 0.25) MeV for the 7/2 − [514] α = −1/2 (α = +1/2) band, and at ω ≈ 0.175 MeV for the 1/2 − [521] α = −1/2 band, respectively. Further investigations show that the band-crossing frequencies are quadrupole deformation dependent.
