The existence of infinitely many solutions is established for a class of nonlinear functionals involving the p-biharmonic operator with nonhomoge- neous Neumann boundary conditions. Using a recent critical-point theorem for nonsmooth functionals and under appropriate behavior of the nonlinear term and nonhomogeneous Neumann boundary conditions, we obtain the result.

Keywords: Positive solutions Third-order three-point BVPs Nonhomogeneous Fixed point theorem Existence and nonexistence a b s t r a c t In this work, by employing the Guo–Krasnosel'skii fixed point theorem and Schauder's fixed point theorem, we study the existence and nonexistence of positive solutions to the third-order three-point nonhomogeneous boundary value problem u (t) + a(t)f (u(t)) = 0...

In this paper, we address the cell averaging (CA), greatest of (GO), and smallest of (SO) constant false alarm rate (CFAR) processors for code acquisition in homogeneous and nonhomogeneous environment. The performance characteristics of the CA, GO, and SO processors are obtained and compared when receiving antenna diversity is employed in the pseudonoise code acquisition of direct-sequence code...

We consider the periodic solutions of a semilinear variable coefficient wave equation arising from forced vibrations nonhomogeneous string and propagation seismic waves in nonisotropic media. The characterizes inhomogeneity media its presence usually leads to destruction compactness inverse linear operator with periodic-Dirichlet boundary conditions on range.

This paper is devoted to a study of multivariate nonhomogeneous reenement equations of the form (x) = g(x) +

We prove the existence and multiplicity of solutions for a nonhomogeneous elliptic equation involving decaying cylindrical potential and critical exponent.

Forward scattering effects have been studied and compared when nonhomogeneous medium is illuminated by coherent and quasi-noise sources operating in mm-wave and microwave ranges. Double-layers dielectric structure simulating Fabry-Perot resonator properties was employed to develop a relevant model used for comparing transmittances of both coherent and noise signals. Experiments with nonhomogene...
