Bankruptcy risk forecasting for the metallurgical branch in Romania

All investment decisions require a thorough analysis of the retrospective evolution of the entities from the concerned area, in order to estimate the long-term evolution perspectives. In this context, the present study analyzes the evolution of the entities from the Romanian metallurgical sector based on the accounting and financial information published for the period 2008 - 2012 and, in fact, it justifies the situation from the perspective of users (managers, investors, auditors) and of the economic environment specific to Romania. Starting from this premise we created a regression model particularly useful in forecasting the evolution of the ability to deal with debt for the entities from the Romanian metallurgical sector

Determinant factors for the growing of shareholders’ equity in the metallurgical sector in Romania

The article provides a statistical monograph of the financial position and performance for the period 2008 – 2012 of the entities from the Romanian metallurgical sector whose financial statements in the period 2004 – 2012 have become the object of the financial audit. There are tested five types of regression models in order to separately determine the evolution of equity in accordance with the variation of turnover, total assets, average number of employees and net result. After determining the most appropriate simple regression model, one proceeds at establishing a multiple regression model which would simultaneously reflect the evolution of equity in accordance with the above mentioned variables. The study’s importance is enhanced by certain statistically-based concrete measures which management should consider in order to increase the shareholders’ equity

A Static Optimality Transformation with Applications to Planar Point Location

Over the last decade, there have been several data structures that, given a planar subdivision and a probability distribution over the plane, provide a way for answering point location queries that is fine-tuned for the distribution. All these methods suffer from the requirement that the query distribution must be known in advance. We present a new data structure for point location queries in planar triangulations. Our structure is asymptotically as fast as the optimal structures, but it requires no prior information about the queries. This is a 2D analogue of the jump from Knuth's optimum binary search trees (discovered in 1971) to the splay trees of Sleator and Tarjan in 1985. While the former need to know the query distribution, the latter are statically optimal. This means that we can adapt to the query sequence and achieve the same asymptotic performance as an optimum static structure, without needing any additional information.Comment: 13 pages, 1 figure, a preliminary version appeared at SoCG 201

Convergence and stability theorems for the Picard-Mann hybrid iterative scheme for a general class of contractive-like operators

In this paper we use the general class of contractive-like operators introduced by Bosede and Rhoades (J. Adv. Math. Stud. 3(2):1-3, 2010) to prove strong convergence and stability results for Picard-Mann hybrid iterative schemes considered in a real normed linear space. We establish the strong convergence and stability of the Picard iterative scheme as a corollary. Our results generalize and improve a multitude of results in the literature, including the recent results of Chidume (Fixed Point Theory Appl. 2014:233, 2014)
