Abstract: Nuclear Electric quadrapole moments Q in 58Ni for some selected levels have been investigated and calculated through Nuclear shell model and considering of 56Ni as an inert core with two active neutrons in a model space (2p3/2, 1f5/2 and 2p1/2) and the configuration mixing of the original states is also done. F5Pvh interaction has been utilized as a two body interaction to generate model space vectors with harmonic oscillator potential as a single particle wave function. OXBASH code is used to carry this calculations and the program of Core, Valence, Tassie (CVT) written in FORTRAN go language to calculate the Electric quadrapole moments between excited states themselves. All of these calculations have been carried through model space vectors only. One body density matrix elements (OBDM) for ground and Excited states is calculated in order to carry the calculations using single particle Transition matrix elements between excited states theme selves.

Abstract: In this paper, the nonconservative systems with second order Lagrangian are investigated using fractional derivatives. The fractional Euler Lagrange equations for these systems are obtained. Then, fractional Hamiltonian for these systems is constructed, which is used to find the Hamilton's equations of motion in the same manner as those obtained by using the formulation of Euler Lagrange equations from variational problems, and it is observed that the Hamiltonian formulation is in exact agreement with the Lagrangian formulation. The passage from the Lagrangian containing fractional derivatives to the Hamiltonian is achieved. We have examined one example to illustrate the formalism.

Abstract: The skin aging process, e.g. wrinkles and sagging, caused by not only aging but also ultraviolet irradiation, could be related to the depression of metabolic function. Therefore, an in vivo quantitative measurement of capillary blood flow velocity governing skin metabolism functionally, i.e. microcirculation, is crucial to clarify the skin aging and to create skincare products. The purpose of this study is to visualize the tomographic velocity of red blood cell in capillaries just below human epidermal skin using Optical Coherence Doppler Velocigraphy, namely OCDV. This was constructed on a low coherence interferometer, which could provide tomographic distribution of flow-modulated Doppler frequency by developing OCDV algorithm of Hilbert transform and adjacent autocorrelation. In order to validate OCDV system, this was in vivo applied to human forearm skin under respective mechanically stimulated conditions of control and avascularization. As a result, a cross-sectional imaging of blood flow velocity was found to display not only morphological OCT images but also networks of capillary vasculature inside dermal tissue. It was confirmed that blood flow velocity further decreased in upper dermis under avascularization than control condition. Additionally, OCDV could provide a velocity map of blood flow having sensitivity to mechanical stimulus, so has strong efficacy to diagnose “Capillary Angio-Dynamics” of skin tissue. In conclusions, OCDV system could be quite useful for a micro-tomographic imaging of blood flow velocity of capillaries inside skin.

Abstract: Ant tracking technique is a widely used seismic interpretation method of identifying faults in the field of oil and gas exploration and development. However, due to its poor noise immunity, the fault identification effect of ant tracking could be easily affected by the quality of seismic data. Usually, two types of methods can be used to improve the effect of ant tracking, to improve the algorithm of ant tracking or to remove the noise of the seismic data. The first method is usually carried out by the research personnel, and it will take quite a long time before it can be integrated into the software, therefore, the de-noising method is more realistic for the interpreters. This paper puts forward a method of improving the effect of ant tracking by using AC component filtering of reflected intensity. In this method, the structural orientation filtering of the original seismic data is carried out first, and then a coherence cube is calculated based on multiple seismic trace dip scanning. Next, a filtering will be carried out on the coherence cube by using the AC component of the reflected intensity, and then the positive value after the filtering will be set to zero. Finally, the ant tracking will be processed based on the data volume. The improved ant tracking has a better fault identification effect with a higher fault identification rate, which is more favorable for the detailed interpretation of faults.
