In this paper, we present some gradient projection algorithms for solving optimization problems with a convex-constrained set. We derive the optimality condition when the convex set is a cone and under some mild assumptions, we prove the convergence of these algorithms. Finally, we apply them to quadratic problems arising in training support vector machines for the Wisconsin Diagnostic Breast Cancer (WDBC) classification problem.

A Control Chart can be designed based on heuristic, statistical, economic or economic statistical assumptions. When a control chart such as multivariate cumulative sum (MCUSUM) control chart is employed to monitor a production process, three parameters should be determined; subgroup size, sampling frequency and the control limits. This paper provides an algorithm for economic-statistical designing the PPCUSUM control charts parameters based on simulation approach. Finally, example and sensivity analysis are presented.

Today, countries’ power projection, along with tangible and intangible elements of power, is considered as one of the indicators of national power which through them, a country fulfills its demands by using consequences of power elements. Depending on the amount of this power, the scope and the range of countries’ power projection differs from each other. Although, many international scholars pay attention to the U.S. and Russia’s elements of strength and power projection as the world's greatest military powers, however, the prospect of China’s continuous and increasing economic growth considers the country’s likely increase of power projection.Thus, by viewing the concept of power projection, in this article, we will examine its elements in relation with China and then, with a comparative look, we study China’s power projection at regional and international level.

Objective: To examine the efficiency of both the Zeta and density gradient centrifugation (DGC) methods for the selection of normal chromatin sperm by TUNEL, sperm chromatin dispersion (SCD), acridine orange and chromomycin A3 (CMA3).Materials and Methods: The study was performed on 63 patients. Semen analysis was carried out according to WHO criteria. Semen samples were divided into three equal portions. One portion was used as the control, the second portion was used for the Zeta method and the third portion underwent DGC method. All portions were evaluated for sperm morphology (Diff Quick staining), protamine deficiency (CMA3) and DNA integrity (SCD, AO and TUNEL). Coefficients of correlation and student’s t test were carried out using SPSS 11.5.Results: The mean percentage of abnormal sperm, protamine deficiency and DNA fragmentation in the Zeta and DGC methods were significantly decreased as compared to the control group (p<0.005). In addition, the DGC method was higher in comparison to the Zeta method in the selection of sperm with normal morphology (p<0.005). The Zeta method was higher in comparison to the DGC method in the selection of sperm with intact DNA (p<0.005).Conclusion: Both Zeta and DGC methods were effective in the selection of sperm with better quality in terms of normal morphology, normal protamine content and DNA integrity. Therefore, we suggested that the combined Zeta and DGC method should be used for selection of normal sperm.

In this paper, simultaneous control of source terms is considered in a vibrational string problem. In the considered problem, the terms to be controlled are the force and the initial velocity functions. We state the generalized (weak) solution about the considered problem. The existence and uniqueness of the solution for optimal control problem is investigated. The Frechet derivative of the functional and the Lipschitz continuity of the gradient are investigated. Minimizing sequence is obtained by the method of the projection of the gradient.

Personification is one of the most important figures of speech that are manifested in poetry in several forms. Personification usually accompanies figures of speech such as ambiguity, pun, simile etc. Personification as a kind of metaphor or simile has got two bases; 'person' and 'thing', i.e. inanimate object. Whenever we attribute a human attribute or activity to or project a spiritual state and human activity into inanimate objects, the result is personification. Personification is one of the most important dimensions of beauty in Hafiz's poetry. Hafiz personified in different ways and in numerous forms and, in fact, his skill in doing so was excellent. The most important devices in Hafiz's personification include simile, metaphor, and ambiguity that occur in the ground of metaphor.
