Modified Dynamic Id-Based User Authentication Scheme Resisting Smart-Card-Theft Attack, Toan Thinh Truong, Minh Triet Tran, Anh Duc Duong May 2014

Modified Dynamic Id-Based User Authentication Scheme Resisting Smart-Card-Theft Attack, Toan Thinh Truong, Minh Triet Tran, Anh Duc Duong

Applied Mathematics & Information Sciences

Wireless environments such as GSM, 3G, and 4G are more and more popular. Consequently, communications in such networks need to be guarded. It is necessary to have a secure mutual authentication scheme to defend transactions between user and service provider against illegitimate adversaries. Especially, users are those vulnerable to attacks and there are many authentication schemes with smart-card proposed to protect them. Recently, Yung-Cheng Lee has suggested a dynamic identity based user authentication scheme to resist smart-card-theft attack. Nevertheless, he assumed that smart-card is tamperproof. In our opinion, this is not appropriate because Kocher and Messerges pointed that smart-card’s confidential …

In this paper, we introduce and consider a new system of extended general variational inequalities in Banach spaces. We establish the equivalence between the extended general variational inequalities and the fixed point problems. We use this equivalent formulation to suggest some iterative methods for solving this new system.We prove the convergence analysis of the proposed iterative methods under some suitable conditions. Several special cases, which can be obtained from main results are discussed. The idea and technique of this paper may stimulate further research activities in these fields.

Applied Mathematics & Information Sciences

In Appadu(2012d), we have used the technique of Minimized Integrated Exponential Error for Low Dispersion and Low Dissipation, (MIEELDLD) to construct high order methods with low dispersion and low dissipation properties which approximate the 1D linear advection equation. Modifications to the spatial discretisation schemes constructed by Lockard et al. (1995), Zingg et al. (1996) and Bogey and Bailly (2002) have been obtained and also a modification to the temporal scheme developed by Tam et al. (1993) has been devised. These novel methods obtained using MIEELDLD are more effective in terms of shock-capturing properties as they require less number of points …

Solving Fully Fuzzy Linear System With The Necessary And Sufficient Condition To Have A Positive Solution, Ghassan Malkawi, Nazihah Ahmad, Haslinda Ibrahim

Applied Mathematics & Information Sciences

This paper proposes new matrix methods for solving positive solutions for a positive Fully Fuzzy Linear System (FFLS). All coefficients on the right hand side are collected in one block matrix, while the entries on the left hand side are collected in one vector. Therefore, the solution can be gained with a non-fuzzy common step. The necessary theorems are derived to obtain a necessary and sufficient condition in order to obtain the solution.The solution for FFLS is obtained where the entries of coefficients are unknown.

Many numerical experiments are performed to calculate the vortex filaments development in superfluid helium II. We explained how the total length density, the number of vortex points, the velocity, reconnection events and average inverse radius of curvature are affected by both counterflow and temperature. We find that the vortex rings extend fast and the helical disturbances of vortex …

Yearly Electricity Consumption Forecasting Using A Nonhomogeneous Exponential Model Optimized By Pso Algorithm, Xiaomin Xu, Dongxiao Niu, Ming Meng, Huifeng Shi

Applied Mathematics & Information Sciences

Yearly electricity consumption trends of most developing countries usually exhibit approximately exponential growth curves. An optimized nonhomogeneous exponential model (ONEM) is proposed as a method of forecasting electricity consumption by using trend extrapolation. The parameters of the nonhomogeneous exponential equation are obtained by using the inverse accumulated generating operation, discretizing the differential equation, minimizing the residual sum of squares (RSS), and accumulating the homogeneous exponential equation. Furthermore, to improve forecasting precision, particle swarm optimization (PSO) algorithm is used to optimize the equation parameters. To evaluate the forecasting performance for comparison, the said model and two other traditional methods are used …


Mathematical Modeling Towards The Dynamical Interaction Of Leptospirosis, Muhammad Altaf Khan, Saeed Islam, Sher Afzal Khan May 2014

Mathematical Modeling Towards The Dynamical Interaction Of Leptospirosis, Muhammad Altaf Khan, Saeed Islam, Sher Afzal Khan

Applied Mathematics & Information Sciences

In this work, we extend the mathematical model of leptospirosis disease by taking into account the exposed individuals, the related death rate and the transmission coefficients between susceptible human and infected vector. Initially, we present the local asymptotical stability of both the disease-free and endemic equilibrium. We use the Lyapunov function theory with some sufficient conditions. This shows the global stability of both the disease-free and endemic equilibrium. Further, we present the bifurcation of the model and exhibit that the local asymptotical stability of the disease-free and endemic equilibrium co-exists with the threshold quantity. Finally, we discuss the numerical results.

Applied Mathematics & Information Sciences

In the present investigation we have studied the peristaltic flow of a couple stress fluid in a non-uniform rectangular duct. The flow is investigated in a wave frame of reference moving with the velocity c away from the fixed frame.

The exact solutions of velocity and pressure gradient have been found under lubrication approach. The pumping characteristics, axial pressure gradient, velocity field and trapping phenomena have been discussed to highlight the physical features of emerging parameters of couple stress fluid.

Linear Recursive Automotive Target Tracking Filter For Advanced Collision Warning Systems, Seul-Ki Han, Won-Sang Ra, Ick-Ho Whang, Jin Bae Park

Applied Mathematics & Information Sciences

This paper proposes an improved automotive target tracking scheme using FMCWradar which is necessary for the advanced collision warning systems. Since there exist strong nonlinear relationships between the FMCWradar measurements and the target state, the target tracking and data association in dense road clutters have been recognized as a quite challenging problem. It is obvious that the use of accurate range rate measurement might be an excellent choice to improve both target tracking and clutter suppression performances. This motivates us to develop a novel linear recursive automotive target tracking filter based on the measurement conversion in the predicted line-of-sight (LOS) …

Applied Mathematics & Information Sciences

Recently, a multigranulation rough set (MGRS) has become a new direction in rough set theory, which is different from the Pawlake’s rough set since the former takes multiple granulations on the universe into account.

Furthermore, several important measurements …

Exploration of large and high-dimensional data sets is one of the main problems in data analysis. Self-organizing feature maps (SOFM) is a powerful technique for clustering analysis and data mining. Competitive learning in the SOFM training process focuses on finding a neuron that its weight vector is most similar to that of an input vector. SOFM can be used to map large data sets to a simpler, usually one or two-dimensional topological structure. In this paper, we present a new approach to acquisition of initial fuzzy rules using SOFM learning algorithm, not only for its vector feature, but also for …
