Transmitting boundary conditions (tbcs) are developed, suitable for both boundary and finite element analyses, for the radiation of waves propagating in horizontal direction along a compressible inviscid fluid layer. The derivation of the proposed tbcs uses a completely continuum approach and is based on the spectral properties of radiating waves. The formulation is presented in Fourier space and accommodates the effects due to surface waves, as well as, due to the radiation of waves in viscoelastic foundation. The proposed tbcs may be used in the analyses of both dam-reservoir systems and wave load problems of floating or submerged bodies. Here, for assessment, they are used in the analyses of two simple benchmark problems. The results indicate that, when used in conjunction with boundary element analysis, the proposed tbcs not only improve the prediction of BEM, but also reduce the computational load of the analysis.

Domain-Structured Chaos in a Hopfield Neural Network Akhmet, Marat (World Scientific Pub Co Pte Lt, 2019-12-30) In this paper, we provide a new method for constructing chaotic Hopfield neural networks. Our approach is based on structuring the domain to form a special set through the discrete evolution of the network state variables. In the chaotic regime, the formed set is invariant under the system governing the dynamics of the neural network. The approach can be viewed as an extension of the unimodality technique for one-dimensional map, thereby generating chaos from higher-dimensional systems. We show that the dis...
Moving contact problems involving a rigid punch and a functionally graded coating Balci, Mehmet N.; Dağ, Serkan (Elsevier BV, 2020-05-01) Frictional contact mechanics analysis for a rigid moving punch of an arbitrary profile and a functionally graded coating/homogeneous substrate system is carried out. The rigid punch slides over the coating at a constant subsonic speed. Smooth variation of the shear modulus of the graded coating is defined by an exponential function and the variation of the Poisson's ratio is assumed negligible. Coulomb's friction law is adopted. Hence, tangential force is proportional to the normal applied force through the...
Accuracy of the two-iteration spectral method for phase change problems Dursunkaya, Zafer (Elsevier BV, 2006-12-01) The accuracy of the solution of phase change problems using a spectral method is studied. Two iterations in the expansion are used to obtain the interface location of a solidification problem. in semi-infinite domain. Asymptotic expansion of the current approach is compared to the existing analytical solution of the problem, and the validity of the expansion is studied. The results indicate the accuracy of a numerical application of the current approach to finite and semi-infinite geometries. (c) 2005 Elsev...
Exact and FDM solutions of 1D MHD flow between parallel electrically conducting and slipping plates Arslan, Sinem; Tezer, Münevver (Springer Science and Business Media LLC, 2019-08-01) In this study, the steady, laminar, and fully developed magnetohydrodynamic (MHD) flow is considered in a long channel along with the z-axis under an external magnetic field which is perpendicular to the channel axis. The fluid velocity u and the induced magnetic field b depend on the plane coordinates x and y on the cross-section of the channel. When the lateral channel walls are extended to infinity, the problem turns out to be MHD flow between two parallel plates (Hartmann flow). Now, the variations of u...
Shunting inhibitory cellular neural networks with strongly unpredictable oscillations Akhmet, Marat; Tleubergenova, Madina; Zhamanshin, Akylbek (Elsevier BV, 2020-10-01) The paper considers a new type of solutions for shunting inhibitory cellular neural networks (SICNNs), strongly unpredictable oscillations. The conditions for the existence, uniqueness and stability of the solutions are determined. Numerical examples are given to show the feasibility of the obtained results.
