The most common organisms on Earth are plants, which are crucial to the maintenance of atmospheric composition, nutrient cycling and other ecosystem processes. The classification of plants is vital to the study of plant genetic diversity and ecological sensitivity, which is also helpful for many problems such as feeding the population and fighting disease. In this paper, we firstly dicuss the shortages of LDA, then classify the plant by using PCA+LDA. The experiments show that it is effective and feasible for plant classification.

Based on Maximum margin criterion (MMC), a new algorithm, named modified MMC, is proposed for supervised dimensionality reduction in this paper. The algorithm aims at learning a linear transformation, and aims at maximizing the average margin between classes in the projected space. After projecting, the considered pair wise points within the same class are as close as possible, while those between different classes are as far as possible. The performance on two gene expression profiles datasets demonstrates the effectiveness of the proposed method.

Compare to developed countries, e-Government implementation in developing countries seems to be slower. One of the important issues for the e-Government services is adoption of users. Finding the factors which impact on the adoption of government e-Services would lead the managers to a better technology adoption model which is more suitable for e-Government. This study presents the essential factors based on the interviews with the IT managers in the public organization using e-Government services. This study uses the most discussed adoption models to identify the factors. Based on interviews done in Iran's public organizations, this study finds the suitable factors and includes trustworthiness as an external key factor influencing the adoption of e-Government services.

In this paper, we investigate the persistence of a class of predator-prey system with double density restrict and Holling IV type functional response, the existence and the global stability of its global positive periodic solution by using Comparability Theorem, Coincidence Degree Theory and Lyapunov functions. We obtain the sufficient conditions which guarantee the existence of the global asymptotic stable positive periodic solution of the periodic system. Some new results obtained.

In this paper, we present a modification of the two-step Newton's method which produces a class of one-parameter iterative methods for solving nonlinear equations. An interpolating polynomial is constructed to avoid the evaluation of derivative. The convergence analysis shows that the new methods are third-order convergent and require one function and two first derivative evaluations per iteration. Several numerical examples are given to illustrate the performance of the presented methods.

In this paper, a virus infection dynamics model with nonlinear immune response is studied. By analyzing the corresponding characteristic equation, the local stability of each of feasible equilibri of the model is discussed. By constructing appropriate Lyapunov functional, the global stability of the infection-free equilibrium and the immune-free infection equilibrium and virus infection equilibrium are proved. Numerical simulations are carried out to illustrate the theoretical results.

We propose a combined Newton method for solving the symmetric conic linear programming based on the Chen-Harker-Kanzow-Smale smoothing function. The proposed algorithm combines the techniques used in both non-smoothing Newton methods and smoothing Newton methods. Under mild assumptions, the algorithm needs to perform at most one line search at each iteration and is shown to possess global convergence.
