Energy Consumption Balancing In Olsr Ad Hoc Wireless Routing Protocol, Nabil Ghanem, Habiba Belleili
Energy Consumption Balancing In Olsr Ad Hoc Wireless Routing Protocol, Nabil Ghanem, Habiba Belleili
Applied Mathematics & Information Sciences
The Mobile computer science requires many processing. Besides the communication activities, the energy consumption is one of the most critical issues as far as the batteries mobile devices are concerned. Especially, in ad hoc networks where each node is responsible to transmit data packets for the neighbour nodes. Thus, a particular wariness must be taken not only to minimize all nodes appropriate energy consumption but also to balance the batteries individual levels. Any unbalanced energy usage can, however, cause a failure on one of the overloaded nodes and thus lead to partitioning and decreasing the network lifetime. In the present …

Annular Regions Containing All The Zeros Of A Polynomial Via Special Numbers, Eze R. Nwaeze
Applied Mathematics & Information Sciences
In this paper, we obtain some results concerning annular regions containing all the zeros of a given polynomial. These annular regions have radii in terms of the Bell numbers, Pell numbers, Stirling numbers, Fibonacci numbers, Motzkin numbers, Catalan numbers, and/or the Schr¨oder numbers. Also, we show, by means of examples, that for some polynomials our results sharpen some of the known results in this direction.
Algebraic Iterative Reconstruction-Reprojection (Airr) Method For High Performance Sparse-View Ct Reconstruction, Ali Pour Yazdanpanah, Emma E. Regentova, George Bebis
Algebraic Iterative Reconstruction-Reprojection (Airr) Method For High Performance Sparse-View Ct Reconstruction, Ali Pour Yazdanpanah, Emma E. Regentova, George Bebis
Applied Mathematics & Information Sciences
The reconstruction from sparse- or few-view projections is one of important problems in computed tomography limited by the availability or feasibility of a large number of projections. Working with a small number of projections provides a lower radiation dose and a fast scan time, however an error associated with the sparse-view reconstruction increases significantly as the space sparsity increases that may cause the reconstruction process to diverge. The iterative reconstruction-re-projection (IRR) algorithm which uses filtered back projection (FBP) reconstruction has been used for the sparse-view computed tomography applications for several years. The IRR-TV method has been developed as a higher …

Pairing-Friendly Curves With Discrete Logarithm Trapdoor Could Be Useful, Parshuram Budhathoki, Thomas Eisenbarth, Rainer Steinwandt, Adriana Suarez Corona
Applied Mathematics & Information Sciences
Pairing-friendly curves and elliptic curves with a trapdoor for the discrete logarithm problem are versatile tools in the design of cryptographic protocols. We show that curves having both properties simultaneously enable a non-interactive protocol for identitybased 3-party key distribution and deterministic identity-based signing with “short” signatures. All our protocols are in the random oracle model.

Adapted Basic Connections On The Big-Tangent Manifold, Adelina Manea, Cristian Ida
Applied Mathematics & Information Sciences
In this paper we give local characterisations for basic connections adapted to vertical foliation and subfoliations on the big-tangent manifold T M of a Riemannian space (M,g).

Finally, we give an application of these connections in study of Lagrangians on the big-tangent manifold and also, we write in a simple form the equation of motion for scalar fields on the big-tangent manifold.

Applied Mathematics & Information Sciences
Scientists have been gaining inspiration from several natural processes and systems to find fine solutions in many complex hard to solve engineering problems for many years now. Nevertheless, most of these natural systems suffer from great amount of time to perform; thus, scientists are seeking for computational tools and methods that could encapsulate in a conscious way nature’s genius, dealing at the same moment with time complexity. In this conquest, Cellular Automata (CA) proposed long time ago by John von Neumann, can be considered as a promising candidate. CA have the ability to capture the essential features of systems in …

Ikeda Map And Phase Conjugated Ring Resonator Chaotic Dynamics, V. Aboites, D. Liceaga, A. Kiryanov, M. Wilson
Applied Mathematics & Information Sciences
The dynamical behavior of a laser beam confined within a ring-phase-conjugated resonator modeled with a chaos generating element based on the Ikeda map is presented. Using the matrix ray optics, explicit expressions are obtained for the elements of the 2x2 dynamical matrix, which is found in terms of the specific map parameters, state variables and resonator parameters. The phase diagrams obtained show that the so called Ikeda map beams present complex dynamics, including critical points and metastability.

Applied Mathematics & Information Sciences
In this work, a characterization of different properties of p-ary local Frobenius rings and their generating characters is given. Using the generating character, a general form for the homogeneous weights of such rings is described. In particular it is shown that the homogenous weights of all such rings have two non-zero values. Moreover, distance-preserving, linear Gray maps for the homogeneous weights of some classes of p-ary local Frobenius rings are found and using the Gray image, many linear p-ary codes attaining the Griesmer bound are counstructed.

Co-Dynamics Of Trypanosomiasis And Cryptosporidiosis, Kazeem Oare Okosun, Mirirai Mukamuri, Oluwole Daniel Makinde
Applied Mathematics & Information Sciences
In this paper a mathematical model for trypanosomiasis-cryptosporidium co-infection dynamics is investigated to give a theoretical mathematical account of the impact of cryptosporidiosis on trypanosomiasis dynamics. The model steady states are analyzed. The disease-free equilibrium is shown to be locally asymptotically stable when the associated epidemic basic reproduction number for the model is less than unity. The trypanosomiasis only and the cryptosporidiosis only model are each found to exhibit transcritical and backward bifurcation phenomena respectively. While the co-infection model exhibits the possibility of multiple endemic equilibria. From the sensitivity analysis, the trypanosomiasis reproductive number Rlt 0 is more sensitive to …

Supra Semi Open Soft Sets And Associated Soft Separation Axioms, A. M. Abd El-Latif, Rodyna A. Hosny
Applied Mathematics & Information Sciences
In this paper, we introduce and investigate some weak soft separation axioms by using the notion of supra semi open soft sets. We study the relationships between these new soft separation axioms and their relationships with some other properties. As a consequence the relations of some supra soft separation axioms are shown in a diagram. We show that, some classical results in general supra topology are not true if we consider supra soft topological spaces instead. For instance, if (X,m,E) is supra soft semi T1-space need not every soft singleton xE is supra semi closed soft.

A Comparative Study Of A Face Components Based Model Of Ethnic Classification Using Gabor Filters, Hajra Momin, Jules-Raymond Tapamo
Applied Mathematics & Information Sciences
The determination of ethnicity of an individual can be very useful in face recognition and person identification. In this paper, we propose a model of ethnic classification of a person from face images. The proposed model detects facial landmarks such as eyes, nose and mouth in a face image and then applies Gabor filters to each component to extract key facial features. K-Means, Naive Bayesian(NB), Multilayer Perceptron(MLP), SVM(Support Vector Machines) are then used to classify the human face image into different ethnic groups. Classification is performed in 2-class ( Asian and Non- Asian), 3-class (Asian,White and Black) or 4-class (Asian, …

In this paper we present a generalization of Sz´asz operators using the Dunkl generalization of the exponential function. We investigate approximating properties for these operators using the Korovkin approximation theorem and the weighted Korovkin-type theorem.We obtain quantitative estimates by using the modulus of continuity and the rate of convergence for functions belonging to the Lipschitz class. Furthermore, we obtain the rate of convergence in terms of the classical, the second order, and the weighted modulus of continuity.
