 Metric relations in the plane obtained by using complex numbers Author: Teodora Andrica Abstract: The main purpose of this paper is to obtain some important metric relations in the Euclidean plane by using complex numbers. In the first Section we prove the Lagrange's formula and we derive a generalization of the well-known Stewart's relation. Section 2 is devoted to Zarantonello's inequality and to its connection to the problem of finding the group of plane isometries.

PDF | No. of downloads: 187 A generalization of Radon's Inequality Author: Dumitru M. Bătinețu-Giurgiu / Ovidiu T. Pop Abstract: In this paper we prove a generalization of Radon's Inequality and give some applications. PDF | No. of downloads: 195 Certain aspects of some geometric inequalities Author: M. Bencze / N. Minculete / O. T. Pop Abstract: In this paper we prove some new inequalities for the triangle. We also improve Euler's Edwards and Weitzenbock inequalities. PDF | No. of downloads: 163 On the generalized CoÅŸniÅ£Äƒ-Turtoiu inequalities Author: Vasile Berinde Abstract: The aim of this note is twofold: first, to give a simple proof to a simplified version of a result of Y.-D. Wu and M. Bencze "The refinement and generalization of a double CoÅŸniÅ£Äƒ-Turtoiu inequality with one parameter", Creat. Math. Inf. 19(2010), No. 1, 96 - 100 and, secondly, to extend this one parameter CoÅŸniÅ£Äƒ-Turtoiu inequality to a two parameters inequality. PDF | No. of downloads: 160 Some new extensions on Hilbert's integral inequality and its applications Author: Shi Yanping / Mihaly Bencze / Gao Mingzhe Abstract: PDF | No. of downloads: 161 Empirical study of a Pade type accelerating method of Picard iteration Author: Oana Bumbariu / Vasile Berinde Abstract: We use a Pade type acceleration technique for the method of successive approximations in [J. Biazar and A. Amirteimoori, "An improvement to the fixed point iterative method}, Applied Mathematics and Computation \textbf{182} (2006), 567-571, doi:10.1016/j.amc.2006.04.019] to empirically study the possibility of accelerating Picard iteration for some other known test functions. PDF | No. of downloads: 143 Modelling normal boiling points of alkanes by linear regression using the SD index Author: Zoița Mărioara Berinde Abstract: Multiple linear regression methods based on the SD index, introduced previously by the author are used to develop quantitative structure-property models for estimating the normal boiling points of alkanes. The performance of the SD index, in this application, is comparable to the performance of the Wiener number and Harary index. PDF | No. of downloads: 134 An implementation of the piecewise-linear homotopy algorithm for the computation of fixed points Author: Andrei Bozântan Abstract: This paper describes the main aspects of the piecewise-linear homotopy method'' for fixed point approximation proposed by Eaves and Saigal "Homotopies for computation of fixed points on unbounded regions", Mathematical Programming 3 (1972), 225-237]. The implementation of the method is developed using the modern programming language C# and some interesting details are given. PDF | No. of downloads: 150 A weighted inequality involving the sides of a triangle Author: Jian Liu Abstract: A new weighted inequality involving the sides of a triangle is proved by applying the method of the Difference Substitution, and, as an application, a geometric inequality involving an interior point of the triangle is derived. Finally, two related conjectures which are checked by computer are put forward. PDF | No. of downloads: 167 A simple proof of Gautschi-Kershaw inequality Author: Cristinel Mortici Abstract: The aim of this paper is to give a simple proof of Gautschi-Kershaw inequality. PDF | No. of downloads: 178 Some results on integrals computation and applications to logsine and loggamma integrals Author: Cristinel Mortici Abstract: We describe here some methods for computing of some special integrals. The results are applied to the logsine and the loggamma integrals PDF | No. of downloads: 153 Remark regarding two classes of almost contractions with unique fixed point Author: Mădălina Păcurar Abstract: PDF | No. of downloads: 169 On generalized algebraic structures Author: Adina Pop / Maria Sânziana Pop Abstract: This paper deals with the generalized algebraic structures with local neutral element. We present as well several examples of generalized monoids. PDF | No. of downloads: 137 Bezier type curves generated by some class of positive linear operators Author: Ovidiu T. Pop / Dan Bărbosu / Laurian Pișcoran Abstract: PDF | No. of downloads: 144 Methods to evaluate the relationship between survival times Author: N. Todor / G. SÄƒplÄƒcan / M. RÄƒdulescu Abstract: PDF | No. of downloads: 117 The intersection convolution of relations Author: Arpad Szaz Abstract: We initiate a systematic study of the intersection convolution of relations on one groupoid to another. The intersection convolution allows of some natural generalizations of the Hahn-Banach type extension theorems.
