The dynamics of the steady-state Sweet–Parker-type reconnection is analyzed in relativistic regime when energy density in the inflowing region is dominated by magnetic field. The structure of reconnection layer (its thickness, inflow and outflow velocities) depends on the ratio of two large dimensionless parameters of the problem magnetization parameter σ 1 (the ratio of the magnetic to particl...

Trade and Migration with Renewable Natural Resources: Out-of-Steady-State Dynamics Commodity price increases associated with the entry of China, India and other countries into the world economy has led to increased pressure on common-property renewable natural resources (NR). The problem is particularly worrisome for economies that obtain a large share of their income from the exploitation of N...

Analytical solutions have been obtained for both conservative and non-conservative forms of one-dimensional transport and transport-dispersion equations applicable for pollution as a result of a non-conservative pollutant-disposal in an open channel with linear spatially varying transport velocity and nonlinear spatially varying dispersion coefficient on account of a steady unpolluted lateral i...

We present flow-based results from the early stage design cycle, based on computational modeling, of a prototype flow-diverter device, known as the 'Sphere', intended to treat bifurcation aneurysms of the cerebral vasculature. The device is available in a range of diameters and geometries and is constructed from a single loop of NITINOL® wire. The 'Sphere' reduces aneurysm inflow by means of a ...

Detention rockfill dams are an easy and common tool for flood control. Due to their coarse pores, the flow in void spaces is turbulent and non-Darcy. Different relationships introduced by researchers are used to define the hydraulics of the flow within the rockfill materials. The present research is aimed at gaining a better understanding of the difference among these relationships and the sour...
