In this paper, a cubic objective programming problem (COPP) is defined. Introduced a new modification to solve a cubic objective programming problem. Suggested an algorithm for its solution. Also reported the algorithm of the usual simplex method. Application talks about how the developed algorithm can be used to unravel non-linear. The proposed technique, modification simplex technique, can be used with the constructed numerical examples an illustrative numerical problems are given to demonstrate the algorithms.

Beijing Review 2006年第47期49卷 3-页

The article reports on the visit of U.S. Secretary of Commerce Carlos Gutierrez to China from November 13-17, 2006. This is a move of the U.S. to tackle its widening trade imbalance with China. The hardline policy of the U.S. had failed, as shown in its September 2006 current account deficit of $64.3 billion. Gutierrez expressed that exporting to China would improve trade balance between the two countries.

The radial basis function （RBF） interpolation approach proposed by Freedman is used to solve inverse problems encountered in well-logging and other petrophysical issues. The approach is to predict petrophysical properties in the laboratory on the basis of physical rock datasets, which include the formation factor, viscosity, permeability, and molecular composition. However, this approach does not consider the effect of spatial distribution of the calibration data on the interpolation result. This study proposes a new RBF interpolation approach based on the Freedman＇s RBF interpolation approach, by which the unit basis functions are uniformly populated in the space domain. The inverse results of the two approaches are comparatively analyzed by using our datasets. We determine that although the interpolation effects of the two approaches are equivalent, the new approach is more flexible and beneficial for reducing the number of basis functions when the database is large, resulting in simplification of the interpolation function expression. However, the predicted results of the central data are not sufficiently satisfied when the data clusters are far apart.

A new approach is presented by means of a new general ansitz and some relations among Jacobian elliptic functions, which enables one to construct more new exact solutions of nonlinear differential-difference equations. As an example, we apply this new method to Hybrid lattice, diseretized mKdV lattice, and modified Volterra lattice. As a result, many exact solutions expressible in rational formal hyperbolic and elliptic functions are conveniently obtained with the help of Maple.

Glasses and glass ceramics in the system xCeO2·(50 - x)PbO·50B2O3 (0 ≤ x ≤ 50) have been studied, for the first time, by NMR and FTIR techniques. Effect of CeO2 substitution with PbO on NMR parameters has been discussed in terms of changing both boron and cerium coordination. The quantitative fraction of four coordinated boron (N4) has been simply determined from 11B NMR spectroscopy. On the other hand, the fraction of total tetrahedral structural units B4 (BO4 + PbO4 + CeO4) is obtained from FTIR spectral analysis. It is not possible to get the fraction of cerium oxide directly from the applied spectroscopic tools. Therefore, a simple approach is applied, for the first time, to determine CeO4 fraction by using the different criteria of both 11B NMR and FTIR spectroscopy. The fraction of B4 species is equal to N4, within the experimental error, of the same glasses in the composition region of up to 10 mol% CeO2. On the other hand, there is a clear difference between both N4 and B4 values in glasses of higher CeO2 content (>10 mol%). The related difference showed a linear increasing trend with increasing the content of CeO2 in the glass. This was discussed on the bases of structural role of CeO2 which acts as a glass former in the region >10 mol%, while, at lower concentration, it consumed as a glass modifier.
