DownloadMathematical Models Regarding the Basic Informative Elements for the Classical Computers and the Quantum Computers Respectively
Author(s): MALVINA BAICA and MIRCEA CARDU
Abstract: In this paper we use the results obtained in a previous paper [1] regarding the pairs of the DUAL roots (+1 OR -1) and respectively BIPOLAR roots (+1 AND -1) of a couple of equations “seen in the mirror” () and with the help of a mathematical artifice we arrive to the basic informative elements characteristic to the Classical Computers (1 OR 0) and respectively to the Quantum Computers (1 AND 0). In this way we also prove that the two categories of the basic informative elements have a joint origin in the couple of the equations mentioned above.

Author(s): IBTISAM AL-DAWISH and MASLINA DARUS
Abstract: Let denote the class of concave univalent functions defined in the open unit disk . Each function maps the unit disk onto the complement of an unbounded convex set. In this paper, we shall prove that the Libera operator is starlike by finding certain conditions on .
DownloadA New Approach to One-Dimensional Oscillators in Relativistic Quantum Mechanics
Author(s): LAUREAN HOMORODEAN
Abstract: A new approach to the one-dimensional oscillatory motion of a relativistic quantum particle with the spin is presented. It is based on a modified form of the Hamilton operator of the particle. As particular cases, the one-dimensional Dirac oscillator and the one-dimensional oscillator with equidistant energy levels are discussed. In this context, the first oscillator appears as an ancient representative, while the second oscillator is a new representative of an entire class of relativistic quantum one-dimensional oscillators.
DownloadOn the Maximum Term and Lower Order of Entire Monogenic Functions
Author(s): SUSHEEL KUMAR and G.S. SRIVASTAVA
Abstract: In the present paper, we study the growth properties of entire monogenic functions. The characterizations of lower order of entire monogenic functions have been obtained in terms of their Taylor’s series coefficients. Also we have obtained some inequalities between order, type, maximum term and central index of entire monogenic functions.

DownloadOn the Convergence of Modified Noor Iteration Method for Nearly Lipschitzian Mappings in Arbitrary Real Banach Spaces
Author(s): ADESANMI ALAO MOGBADEMU
Abstract: In this present paper, we employed a modified Noor iteration method introduced by Rafiq [9]. Some strong convergence theorems of this iteration scheme are established for three nearly uniformly Lipschitzian mappings if at least one of these maps is uniformly Lipschitzian mapping. Our results extend and improve the recent ones proved by Chang et al., Kim et al., Olaleru and Mogbademu, Ofoedu and many others.
DownloadState Space Approach for Solving Transient Queuing Systems
Author(s): T.S.L. RADHIKA and B.L.R. DEEPIKA
Abstract: In the present paper, we consider a transient queuing system and find its solution using the state space approach. For this, the given interval of study [0,T] is sub divided into small sub intervals, where it is reasonable to assume that the instantaneous arrival and service rates are constants. The system of equations together with the initial conditions is solved for an analytical expression for s’ in each interval. The solution obtained at the right end point of the previous sub interval is taken as the initial condition in the sub sequent interval. The developed method is illustrated for an (M/M/1):(FCFS/m/∞) system.

DownloadPositive Solutions for Second Order Impulsive Differential Equations with Integral Boundary Conditions on Time Scales
Author(s): WENGUI YANG
Abstract: In this paper, a class of second order impulsive differential equations with integral boundary conditions on time scales are considered. Under different combinations of superlineary and sublinearity of nonlinear term and the impulses, some existence, multiplicity, and nonexistence criteria of positive solutions are established based on Guo-Krasnosel’skii fixed point theorem, which are new and complement previously known results.
