R-Preirresolute Functions
Author: C. W. Baker
Abstract: A strong form of a preirresolute function, called R-preirresolute, is introduced. It is established that R-preirresolute implies strongly preirresolute and that R-preirresolute functions satisfy a strong form of the closed graph property. Also it shown that R-preirresolute functions are closely related to pre-regularity.

Coincidence theorems for subadditive and superadditive functions
Author: Pal Burai / Arpad Szaz
Abstract: We give some necessary and sufficient conditions in order that a quasi-subadditive function should coincide with a quasi-superadditive one. Thus, we can easily prove a straightforward extension of a theorem of Marek Kuczma on the linearity of a subadditive function majorized by a differentiable one.

Modern routing techniques for future QoS enabled networks
Author: Sanda Dragoș / Radu Dragoș
Abstract: Modern technologies such as \emph{mobile agents} are ``intelligent'' solutions that can be used to achieve efficient QoS routing in the Internet. We present in this article the key architectural features of this paradigm from the routing perspective. The evolution of a mobile agent population dispatched to find optimal routes is also analyzed. Our experimental results show that a high performance level could be achieved with the cost of generating too much control traffic. We present a solution that overcomes this scalability issue while still providing optimal results.

A note on partially ordered topological spaces and a special type of lower semicontinuous function
Author: S. Ganguly / S. Jana
Abstract: $\theta$-closed partial order in a topological space has been studied in details. $\theta^\star$-lower semicontinuity of a function to a hyperspace has been introduced and such functions are compared to the multifunctions. Lastly the $\theta^\star$-lower semicontinuity of some special types of functions is studied.

Integral operators on certain classes of analytic functions with negative coefficients
Author: V. C. Holhoș / Grigore S.Sălăgean
Abstract: In this paper integral properties of some analytic functions with negative coefficients from certain classes of functions defined using a differential operator are studied. The obtained results are sharp and they are improvement of some known results.

The solution of the thermoelastic equilibrium problem for cylindrical tubes with big torsion angle
Author: Mircea Lupu / Florin Isaia
Abstract: In this paper, the coupled problem of the thermoelastic equilibrium for cylindrical tubes with big torsion angle is solved. The mathematical model of isotropic elastic cylinders with big torsion angle is also presented. Using this new mathematical model, we actually solve the thermoelasticity problem for cylindrical tubes.

On convex feasibility problems
Author: Laura Mărușter / Ștefan Mărușter
Abstract: In this paper we consider a projection method for convex feasibility problem that is known to converge only weakly. Exploiting a property concerning the intersection of a family of convex closed sets, we present a condition that makes them strongly convergent, without additional assumptions.

On the monotonicity of Schurer type polynomials
Author: Carmen Muraru
Abstract: The paper is a study of a sequence of Schurer type operators. It deduces a representation for the difference of two consecutive terms of the sequence of this type operators, by divided differences. Using this representation we enounces some sufficient conditions for the monotonicity of the sequence of Schurer operators.

About a class of linear and positive operators
Author: Ovidiu T. Pop
Abstract: In this article we shall give a general property to a class of linear and positive operators and then, through particular cases we shall obtain statements verified by the Bernstein, Schurer and Stancu operators.

A general common fixed point theorem of Meir and Keeler type for weakly compatible mappings
Author: Valeriu Popa
Abstract: In this paper, using a combination method used in [3], [20] and [22], the result of [16, Theorem 1] is improved by removing the assumption of continuity, relaxing compatibility to weakly compatibility property and replacing the completeness of the space with a set of four alternative conditions for functions satisfying an implicit relation.

Experimental Results on Isolated Speech Recognition System
Author: Gavril Toderean / Marieta Gâta / Alexandru Căruntu
Abstract: In this paper we described the development of Romanian ANN speech recognition system, which uses artificial neural networks. The network, which is composed by a three layer (a Multilayer Perceptron), is trained by conventional Back-propagation algorithm. The ANN speech recognition system based on Mel Frequency Cepstral Coefficients was developed using Matlab toolkit. The system was tested on the 50 isolated word Romanian speech corpus and it was training on a 50 distinct isolated word recognition task. The word recognition accuracy obtained was about 76%.
