Experimental study on radioactive concentration and filter function in SPECT reconstruction;

In this paper, Gauss filter function is used to filter the N S equation and the subgrid scale Reynold stress model is introduced to deduce the practical form of LES equation for 2 D flow calculation of hydraulic machine.

The Gauss filter function is used to filter the Navier stokes equation and the subgrid scale Reynold stresses model is introduced to deduce the practical form of LES equation for two dimensional case and its discrete form on physical plane and computational plane for flow field calculation of hydraulic machine.

According to the working principle and its characteristics, the Filter-hook Drive,is used to create filter function in Windows 2000/XP.

The objective of this paper is to construct a filter function for group multiple-attribute decision-making problem, which can make full use of the high-quality information and filter the low-quality information to sufficiently embody the will of the group.

The first step is to convert equivalently the discrete problem into continuous problem taking advantages of the step-up function; The second step is to define the polish function to approach the step-up function; The third step is to establish the mapping model by introducing the filter function which is the inverse functio.

Using continuous independent topological variables, adopting Taylor expansion and the filtering function, the objective function was expressed approximately as a second-order expression.

Based on the Taylor expansion,the filtering function and the Rayleigh quotient,the objective fu.

Based on the adaptive noise canceling technology,a neuron-based approach which can rebuild the noise adaptively by using the combination of noise base function is proposed.
