Abstract: | This paper deals with the maximum norm analysis of an overlapping Schwarz method on nonmatching grids for a class of evolutionary Hamilton-Jacobi-Belman equations. We consider a domain which is the union of two overlapping subdomains where each subdomain has its own independently generated grid. The grid points on the subdomain boundaries need not match the grid points from the other subdomain. Under a discrete maximum principle, we show that the discretization on each subdomain converges quasi-optimally in the L∞ norm. |

Abstract: | A theoretical formulation that describes energy transformation and dissipation caused by air bubble entrainment in water is developed. To verify the air bubble model for spilling breaking waves, laboratory experiments were carried out with measurements of void fraction distributions. A quantative analysis shows that the ratios of energy dissipation rate caused by bubble entrainment to total dissipation rate have been found to be 18-20% for spilling breakers. Further, the results of the air-bubble model are compared with the laboratory data and the computed results show good agreement except some of discrepancies in the vicinity of the breaking point and near the shoreline. |

Abstract: | The present paper describes a novel method of face recognition based on variance estimation and facial feature extraction. The proposed method uses OpenCV to load boosted haar classifier cascades which allows an initial detection of the faces within a given image. Variance estimation of RGB components is computed to compare the extracted faces and the faces within the database used in comparison. Also a new method to extract facial features is developed based on feature location with respect to face dimensions. Euclidean distance of facial features of the extracted faces from test image and faces extracted from database after variance test is used. The proposed method can be used in face recognition systems such as video surveillance, human computer interfaces, image database management and smart home applications. Results demonstrate the success of the proposed method, which show that our method of detection and verification achieves very encouraging results with good accuracy and simple computations. |

Abstract: | This paper deals with the singularly perturbed boundary-value problem for a non-linear second order delay ordinary differential equation. For the numerical solution of this problem, we use an exponentially fitted difference scheme on a uniform mesh which is accomplished by the method of integral identities with the use of exponential basis functions and interpolating quadrature rules with weight and remainder term in integral form. The method is shown to be uniform convergent of first-order in the discrete maximum norm.Numerical results supporting the theory are presented. |

Abstract: | Abstract The cable equation is one of the most fundamental equations for modelling neuronal dynamics. Due to its significant deviation from the dynamics of Brownian motion, the anomalous diffusion in biological systems can not be adequately described by the traditional Nernst-Planck equation or its simplification, the Cable equation. Recently, a modified Cable equation was introduced for modeling the anomalous diffusion in spiny neuronal dendrites (Henry, Langlands, and Wearne, 2008). The resulting governing equation, the so-called fractional Cable equation, which is similar to the traditional Cable equation except that the order of derivative with respect to the space and/or time is fractional. In this work, a numerical study for the fractional Cable equations which is introduced by using weighted average of finite difference methods. The stability analysis of the proposed methods is given by a recently proposed procedure similar to the standard John von Neumann stability analysis. A simple and accurate stability criterion valid for different discretization schemes of the fractional derivative and arbitrary weight factor is introduced and checked numerically. Numerical results, figures, and comparisons have been presented to confirm the theoretical results and efficiency of the proposed method |

The non-linear partial differential equations and boundary conditions are reduced to a system of non-linear ordinary differential equations and boundary conditions by similarity transformations. Graphs are plotted for various values of the emerging dimensionless parameters of the problem and discussed. A comparison with previously published work on a special case of the general problem was performed and the results were found to be in excellent agreement. Results for the wall shear stress and Sherwood number as well as the details of the velocities and concentration fields are presented for representative governing parameters. |

Abstract: | It is well known that in the classical Shannon sampling theory on band-limited signals, any finitely many missing samples can be recovered when the signal is oversampled at a rate higher than the minimum Nyquist rate. In this work, we consider the problem of recovering missing samples from multi-channel oversampling in a general shift-invariant space. We find conditions under which any finite or infinite number of missing samples can be recovered. |

Abstract: | A new semi-supervised dimensionality reduction method called Semi-supervised Tensor Graph-optimized Linear Discriminant Analysis (STGLDA) for two-dimensional face recognition. Unlike recent proposed Tensor Locally Linear Discriminative Analysis (TLLDA), STGLDA offers some advantages over TLLDA. 1) STGLDA is originated from Graph-based Fisher Analysis (GbFA) while TLLDA is originated from the Local Fisher Discriminant Analysis (LFDA). In contrast to LFDA, GbFA encodes the richer discriminating information and there is no assumption that the data obey Gaussian distribution. 2) With the linear weighted way of fusing Principal Component Analysis (PCA) and GbFA, STGLDA preserves global scatter structure information and Graph-based discriminant information capturing local structure feature. TLLDA only pay attentions to preserve local structure information and discriminant information while ignores preserving global structure information. Experimental results on real face databases demonstrate that STGLDA is highly competitive with TLLDA and other tensor dimensionality reduction algorithm. |

Abstract: | The recent convergence trend of multimedia technology and telecommunications along with the materialization of the Web as a strong competitor of conventional distribution networks have generated an acute need for enrichment in modalities and capabilities of the delivery of digital media. Within this new trend, a main challenge relates to the production of easy adaptable content capable of optimally fitting into evolving and heterogeneous networks as well as iterative delivery platforms with specific content requirements. Network supported multimedia applications involve many different transmission capabilities, including Web based applications, narrowcasting, conventional terrestrial for interactive broadcasting, wireless channels, high definition television for sensitive remote applications, e.g., remote medical diagnosis, etc. These applications are used to deliver content to a wide range of terminals and users surrounded by different environments and acting under totally different circumstances. In this paper, new techniques for the DCT color image coding based on feature extraction are proposed, to study the effect of the edge based color image coding on the compression quality. Moreover, modification of the traditional JPEG method based on edge coding is achieved. In the beginning, the image is subdivided into a block of pixels with different block size. Firstly; the block must be classified as foreground block or background block based on a pre-processing step. The foreground blocks will be compressed via JPEG technique but with significant quantized coefficients and the DC coefficient only from one block in the background is used to code it. A comparative analysis of coding efficiency for the proposed techniques relative to the recent coding methods is introduced in this paper. |

Abstract: | Piezoelectric materials possess really high potential to deliver nano-scale or micro-scale positioning resolution, huge blocking force, and fast response; hence they are widely utilized in a variety of engineering applications and product designs. However, a higher and unacceptable positioning error always occurs due to the hysteresis effect of the piezoelectric materials. For high-precision applications, this natural behavior should be eliminated. For solving this problem, a nonlinear nano-scale control design based on concepts of Bouc-Wen model, system identification, and the nonlinear sliding mode control method is proposed. This proposed design can be divided into the following four steps: 1. Input and output behaviors of piezoelectric materials are firstly mathematically described with Bouc-Wen model, 2. System parameters in Bouc-Wen model for representing the characteristics of piezoelectric materials then simultaneously identified with respect to practical input and output data of piezoelectric materials, 3. Stability verification for this identified Bouc-Wen model should be done in the next, and 4. A nonlinear sliding mode control is elegantly derived finally via minimizing the tracking error performance index. One important contribution of this investigation is that the tracking error between output displacement of mathematical modeled piezoelectric materials and desired trajectory can be proven to exponentially converge to zero. |

Abstract: | ress introduced and studied the concept of the tight span of a metric space. It is known that Dress's theory is equivalent to the theory of the injective hull of a metric space independently discussed by Isbell some years earlier. In a paper by Kemajou et al. it was shown that Isbell's approach can be modified to work similarly for $T_0$-quasi-metric spaces and nonexpansive maps. Continuing that work we show in the present paper that large parts of the theory developed by Dress do not use the symmetry of the metric and when appropriately modified-holds essentially unchanged for $T_0$-quasi-metric spaces. |

Abstract: | In this communication we discuss different aspects of multi-qubit system. Information dynamics of charge qubits coupled to a nanomechanical resonator under influence of both a phonon bath in contact with the resonator and irreversible decay of the qubits is considered. The focus of our analysis is devoted to multi-particle entanglement and the effects arising from the coupling to the reservoir. Even in the presence of the reservoirs, the inherent entanglement is found to be rather robust. Due to this fact, together with control of system parameters, the system may therefore be especially suited for quantum information processing. |

Abstract: | We study a method for estimating parameters of a moving average process. The estimator, called RIVE is based on the idea that all the information for the parameters is transmitted through the sample and the noise effect becomes negligible when n tends to infinity. The case of the MA(1) process is studied. It is show that the estimator RIVE is consistent and asymptotically normal and provides a consistent estimator of the variance of the white noise process. |

This extends some similar results in the case of a diagonal diffusion-operator associated with nonlinearities preserving the positivity and the total mass of the solutions or for which the total mass is a priori bounded. For this purpose, we use the appropriate techniques which are based on comparison theorem and Lyapunov functional methods. |

Abstract: | In this paper, Particle swarm optimization (PSO), a stochastic population-based evolutionary algorithm for problem solving is presented. PSO algorithm which has been successfully applied in many research and application areas is proposed to optimize least square support vector machine (LSSVM) to predict the daily stock prices. Stock market prediction is the act of trying to determine the future value of a company stock or other financial instrument traded on a financial exchange. The successful prediction of a stock's future price will maximize investor’s gains. The proposed model is based on the study of stocks historical data, technical indicators and optimizing LSSVM with PSO algorithm. PSO selects best free parameters combination for LS-SVM to avoid over-fitting and local minima problems and improve prediction accuracy. Artificial neural network trained with Levenberg-Marquardt (LM) algorithm is used as a benchmark for comparison with proposed algorithm. Results presented in this paper show the potential of PSO algorithm in optimizing LS-SVM. |

Abstract: | We formulate and analyzed a compartmental deterministic model for the transmission of malaria disease. The model contain the systems of continuous time ordinary differential equations in compartments involving human and vector(Mastomys nastalensis i.e. Household Rat) population. We imposed a control parameter(vaccination) and treatments in order to prevent and treat the disease occurrence in human. Our model has a disease-free equilibrium that is globally asymptotically stable if the basic reproduction number is less than unity, while the endemic equilibrium exists and it is globally asymptotically stable whenever the basic reproduction number is greater than unity. We further use the optimal control theory , by deriving its necessary conditions for optimal control of the malaria disease using the Pontryagin’s Maximum Principle (PMP).We finally discussed results from our numerical simulation to illustrate our analytical results.

Abstract: | In recent work, Alodat et al. (2009) introduced estimators of the simple linear regression parameters using Median Ranked Set Sampling (MRSS) where the ranking was performed on the response variable. In this paper, we intend to obtain Fisher information matrix of these parameters to assess the amount of information contained in Median Ranked Set Sample compared to its counterpart contained in simple random sample (SRS). Our intention is to point out that, under the same sample size, Fisher information using MRSS contains more information than that contained in a SRS. Also, we present the Maximum Likelihood Estimator (MLE) using MRSS as well as SRS. |

Abstract: | The problem to determine the Euclidean shortest path between two points in a simple polygon is very classical in motion planning. To date, all methods for solving this problem, as presented by Lee and Preparata in 1984, Mitchell in 2000, etc, rely on starting with a triangulation of a simple polygon and then rely on tools of graph theory (Dijkstra's algorithm/Thorup's algorithm for solving shortest path problems on graphs). In 2010, we present an efficient algorithm for determining convex ropes of a simple polygon and the convex hull for a finite set of points in 2D based on the idea of the method of orienting curves (introduced by Phu in 1987 for solving optimal control problems). These problems are variations of the shortest path problem in 2D and thus can be solved without triangulation algorithm and graph theory. There arises a question: Can we solve shortest path problems in 2D and in 3D without graph theory? In this talk, in 2D, based on the idea of the direct multiple shooting method (introduced by Bock in 1984 for solving optimal control problems) for the discretezation of the shortest paths in a simple polygon by cut segments parallel to y-coordinate 0y, we present an algorithm for finding the approximate shortest path between two points inside a simple polygon. It does not rely on triangulation of polygons and graph theory. In the same manner, in 3D, the discretization of the shortest paths on surface of a convex polytope is by cut slices parallel to the plane $x0y$. Then we present an algorithm for finding the approximate shortest path between two points surface of a convex polytope and show that graph tools (e.g., Dijkstra's algorithm/Thorup's algorithm) are crucial in the discretization above. Numerical examples are presented. Thus, in 3D, graph theory plays an crucial role in finding approximate shortest paths on surface of a convex polytope. This is a joint work with N. N. Hai, T. V. Hoai, and L. H. Trang. |

Abstract: | The object of the present paper is to study generalized 'phi-recurrent trans-Sasakian manifolds. It is proved that a generalized 'phi-recurrent trans-Sasakian manifold is an Einstein manifold. Also we obtained a relation between the associated 1-forms A and B for a generalized 'phi-recurrent and generalized concircular 'phi-recurrent trans-Sasakian manifolds and finally proved that a three dimensional locally generalized 'phi-recurrent trans-Sasakian manifold is of constant curvature. |

Abstract: | The work presents a new approach of modeling industrial reactors to receive polymer plastics. The efficient method of identifying stochastic model is suggested, at which unaccounted chance factors are presented as integrated disturbances. The models, received at which allow to take into consideration both the structure of flows in reactors and kinetic peculiarities of the process. |
