Low-resolution and signal-dependent noise distribution in positron emission tomography (PET) images makes denoising process an inevitable step prior to qualitative and quantitative image analysis tasks. Conventional PET denoising methods either over-smooth small-sized structures due to resolution limitation or make incorrect assumptions about the noise characteristics. Therefore, clinically imp...

Trilateralism among the United States, Japan and Korea has significantly contributed to the peace and security of East Asia in the last fifty years. The most important links in the US-Japan-Korea triangle are the US’s bilateral alliances with Japan and South Korea. But trilateralism has been important in issue areas such as policy coordination regarding North Korea. Building on this success, th...

In the paper the potential fluid flow problem in porous media using the Darcy’s law and the continuity equation is solved. Mixed-hybrid finite element formulation based on general trilateral prismatic elements is considered. Spectral properties of resulting symmetric indefinite system of linear equations are examined. Minimal residual method for the solution of systems with a symmetric indefini...

In the paper a mixed-hybrid approximation of the potential uid ow problem based on prismatic discretization of the domain is presented. Trilateral prismatic elements with vertical faces and nonparallel bases suitable for the modelling of real geological circumstances are considered. The set of linearly independent vector basis functions is deened and existence and uniqueness of the approximate ...
