Trends in Neural Computation

These days neural computation has turn into an interdisciplinary box in its personal correct; researches were performed starting from diversified disciplines, e. g. computational neuroscience and cognitive technological know-how, arithmetic, physics, desktop technological know-how, and different engineering disciplines. From various views, neural computation offers an alternate technique to appreciate mind features and cognitive approach and to resolve not easy real-world difficulties successfully.

Nonlinear problems of this type arise in many applications, including steady-state combustion theory where F (w) is an exponential function (cf. Ward et al. (1993)). The primary difference between the linear problem (1) and the unperturbed problem corresponding to (53) is that, depending on the form of the nonlinearity F (w), the unperturbed problem may have no solution, a unique solution, or multiple solutions. We shall assume that the unperturbed problem has at least one solution, and we will focus on determining how a specific solution to this problem is perturbed by the presence of the subdomain Ωε .

Consider the steady-state convection-diffusion equation for T (X), with X = (X1 , X2 ) posed outside two circular disks Ωj for j = 1, 2 of a common radius a, and with a center-to-center separation 2L between the two disks: κ T = U · ∇T , X ∈ R2 \ ∪j=1 Ωj , X ∈ ∂Ωj , j = 1, 2 , T = Tj , |X| → ∞ . T = T∞ , (102a) (102b) (102c) Here κ > 0 is constant, Tj for j = 1, 2 and T∞ are constants, and U = U(X) is a given bounded flow field with U(X) → (U∞ , 0) as |X| → ∞, where U∞ is constant. We introduce the dimensionless variables x, u(x), and w(x) by x = X/γ , T = T∞ w , γ ≡ κ/U∞ .

The constants Aj for j = 1, . . , N and χ satisfy the N + 1 dimensional linear algebraic system defined by (50) and (46). To implement the hybrid method, we must compute the Neumann Green’s function GN and its regular part RN . 3) of Kolokolnikov et al. (2005)) and for a rectangle. In particular, upon representing points as complex numbers, we obtain for the unit disk that GN (x; ξ) = 1 2π − log |x − ξ| − log x|ξ| − ξ 1 3 + (|x|2 + |ξ|2 ) − |ξ| 2 4 , (52a) 1 RN (ξ; ξ) = 2π ξ 3 − log ξ|ξ| − + |ξ|2 − |ξ| 4 .
