The analysis of NMR
data in terms of inversion of relaxation distribution is hampered by the
ill-posed nature of the required solution about the Fredholm integral equation.
Naive approaches such as multi-exponential fitting or standard least-squares
algorithms are numerically unstable and often failed. This paper updates the
application of Tikhonov regularization to stabilize this numerical inversion problem and
demonstrates the method for automatically choosing the optimal value of the
regularization parameter. The approach is computationally efficient and easy to
implement using standard matrix algebra techniques, which is based on mathematical
ware MATLAB. Example analyses arepresented using both synthetic data and experimental
results of NMR studies on the liquid samples like as oils and yoghurt.
this paper, based on the survey data of typical enterprises and a key
university of Guangdong province, we constructed human resource management
professional’s competency features based on social needs. According to the
intrinsic characteristics of the human resource management theory, we put
forward an “integrated teaching model”, namely the integration of human resources
management module of the course content as well as the integration of
theoretical teaching and comprehensive quality training, so as to achieve the
goal of improving teaching effects and meeting the demand of society.
