This paper is concerned on analytical treatment of non-linear differential equation of a viscous boundary layer flow due to a moving sheet. An analytic approximate technique, namely Optimal Homotopy Asymptotic Method (OHAM) is employed into a new version for this purpose. It is proved that OHAM provide accurate solution for the nonlinear differential equation of the third-order with initial and boundary...
This paper describes application of a model for predicting the flash point of binary alcohol mixtures. To confirm the predictive efficiency of the derived flash points values, the model was verified by comparing the predicted values with the experimental data for the selected mixtures. The flash points values determined were similar to those of predicted ones. However, the measured and predicted flash...
In this paper we address the problem of tracking multiple AUVs using acoustic signals. Using For this challenging scenario, we propose to use a Probability Hypothesis Density Filter and present a suitable implementation of the Sequential Monte Carlo PHD filter. It will be demonstrated that a particle filter implementation of the aforementioned filter can be used to successfully track multiple AUVs,...
Uplink sum power minimization problem with required Quality of Service (QoS) under statistical Channel State Information (CSI) and probabilistic constraints in solved for a multicell multiuser scenario. To handle the probabilistic constraints and analyze the system performance, financial risk management measures Value at Risk (VaR) and Conditional Value at Risk (CVaR) are applied. The resulting expressions...
Newton-Raphson and Goldschmidt algorithms can be sped up by using variable latency hardware architectures for rounding division, square root and their reciprocals. A new approach based on a rounding method with remainder estimate calculated concurrently with the algorithm was proposed in [5]. This paper presents an study of the hardware implementation of this approach and shows that does not suppose...
We report on advanced full-wave techniques, both in the frequency and energy domains, aimed at the investigation of the combined electromagnetic-coherent transport problem in pristine graphene, as well as in some 2D-materials beyond graphene, with particular attention to buckleld silicene.
Novel sliding mode control design is proposed for a fractional order system in the presence of disturbance and nonlinear terms on mismatched input channel. This mismatched-channel situation is overcome by using the backstepping method. To authors best knowledge, this is first time to present the noninteger order backstepping approach. In order to demonstrate our design efficiency, some numerical simulations...
Although in semi-cooperative systems, agents are self-interested, they have to help others to get their help in the requirement time. However, designing a distributed method that encourages agents to be truthful and cooperative is challenging. If each agent is able to find useful co-workers to team up with, they are inspired to cooperate with each other, which leads to desirable results for both individuals...
Often new insights and advancements are made by a detailed study of the problem and the solution space. The area of community finding has had many algorithms proposed recently, but to our knowledge there have not been any detailed studies of the solution space. In this paper, we present two algorithms for enumerating and unranking the possible valid community assignments for a network. To demonstrate...
Implicit Runge-Kutta based convolution quadrature and temporal Galerkin approaches to the discretization of the time domain integral equations are combined to produce an accurate efficient solution approach. The underlying method is just the convolution quadrature approach itself, and is used to compute temporal interactions between proximal patches. More distant interactions are computed by a method...
The calculation of Fock-Exchange integral is becoming an important computational challenge in solving the quantum properties of systems with many electrons. In this work we show how techniques that are used in electromagnetic simulations for the similar Poisson equation can help in accelerating the calculation of such exchange integrals. The approach we present can be especially efficient for quasi-planar...
Propagation of short infrared/optical pulses, described by mutual coherence function, in a dilute random medium consisting of large (compared to the wavelength) non-absorbing scatterers is analyzed in the framework of radiative-transfer equation (RTE). A novel and rigorous approach based on analytic complex-contour integration of numerically determined cut and pole singularities of the RTE solution...
Degradation data are widely used in the field of reliability analysis and remaining useful lifetime estimation. Usually, a critical threshold must be defined before both reliability analysis and lifetime estimation is executed. In this paper, we present a method to specify a critical threshold for Wiener degradation process, based on both historical lifetime data and degradation data. The lifetime,...
In this paper we propose a fast matrix multiplication algorithm for Cauchy-like matrices with off-diagonal low-rank property, which uses hierarchically semiseparable (HSS) matrix techniques. We implemented this algorithm in shared memory environment by using OpenMP. The numerical results show it has good speedups and is much faster than the plain matrix-matrix multiplications. For matrices with big...
A novel affine registration technique is proposed which efficiently handles the partial occlusion problem. The proposed method is working without point wise correspondences or radiometric information's. The aligning transformation is found by solving a system of non-linear equations and minimizing the area of occlusions. Each equation is generated by integrating a non-linear function over the foreground...
Aiming at the interval rough numbers of multiple attribute decision making (MADM) problems, a method of ranking interval rough numbers based on possibility degree is proposed. First, the deviation degree for interval rough numbers is given, and then an optimal model with maximum deviation to solve the attribute weights is set up. Second, a possibility degree formula of interval rough numbers is proposed...
According to the response surface methodology (RSM), this paper proposes a new trial vector perturbation model for Differential Evolution(DE). It not only consists of linear and nonlinear heuristics for optimum exploring, but also retains simplicity style of DE mutation operator in appearance which can help the new algorithm absorb many existed elegant methods from a large amount of DE variants. The...
Nonnegative Boltzmann machines (NNBMs) are recurrent probabilistic neural network models that can describe multi-modal nonnegative data. NNBMs form rectified Gaussian distributions that appear in biological neural network models, positive matrix factorization, nonnegative matrix factorization, and so on. In this paper, an effective inference method for NNBMs is proposed that uses the mean-field method,...
This paper proposes a new method for detecting P and T waves in multilead ECG based on the Finite Rate of Innovation(FRI) technique [8]. A simple QRS detection scheme will be presented followed by a novel P and T wave detection algorithm. The novelty here is the modelling of the P and T wave using a Gaussian kernel. Using a 2D wavelet decomposition, the approximation coefficients are windowed based...
Convex power flow relaxations have become popular to alleviate difficulties with embedding the non-convex AC power flow equations into optimisation models, and to provide guarantees on the quality of feasible solutions generated by heuristic approaches. However, their use has almost universally been limited to purely continuous problems. This paper extends the reach of relaxations to reconfiguration...
