In this article, we apply this new method for solving an engineering system withinitial and boundary conditions and integral criterion, and we will use dynamicprogramming as iteration for solving model. تفاصيل المقالة

We suggest a new viscosity iterative scheme for finding a common element of theset of solutions of the general equilibrium problem system (GEPS) and the set ofall common fixed points of two non-commutative non-expansive self mappings in theframework of a real Hilbert space. The results in the paper generalize and improvesome well-known results in Jankaew et al.[2] and many others. Moreover, we presenta numerical example (by using Maple software) to grantee the main result of thispaper. تفاصيل المقالة

In this paper, we introduce a new iterative process for two nonexpansive mapsatisfying the condition (II) in CAT(0) space and establish \Delta-convergence theoremfor the proposed process under condition. تفاصيل المقالة

A new iterative is proposed for finding a common fixed points of multi-valuedquasi nonexpansive mappings and the strong convergence the scheme is proved inCAT(0) spaces. The strong convergence theorem for hemicompact map shown isalso. تفاصيل المقالة

Organizational risk is often defined as a change in the flow of profit, or as a sys-tematic or non-systematic changes in the stock return flow. The risk taking of management is conceptualized as the actual investment decisions that are indictors due to uncertainty results. The purpose of this study is to investigate the effect of financial characteristics on future corporate risk taking behavior. After designing the indicators for assessing financial characteristics, the transaction data were collected from the Stock Exchange in the five-year period of 2011-2015. A sample of 111 companies was selected by sampling method based on the Cochran formula, which resulted in a total of 555 year-firm observations. In this study, linear regression and correlation were used to investigate the hypothesis, and for analyzing data and hypothesis testing, we used Eviews software. What can be said in the summing-up and conclusion of the general test of research hypotheses is that the disproportionate changes in sales costs, advertising costs, rental costs, liquidity, financial leverage, and disproportionate changes in capital costs have a positive impact on future corporate risk taking behavior. In addition, other results indicate a negative impact of disproportionate changes in sales growth, inventory, liquidity, and asset turnover on future corporate risk-taking behavior. The results obtained in this paper are consistent with the documentation referenced in the research's theoretical framework and financial literature.. تفاصيل المقالة

In this paper is introduced a new type of generalization of metric spaces called $S_b$ metric space. For this new kind of spaces it has been proved a common fixed point theoremfor four mappings which satisfy generalized contractive condition. We also present example to confirm our theorem. تفاصيل المقالة
