Sentence examples for extended obstacle from inspiring English sources

Numerical tests for the far-field patterns of scattered fields arising from uniformly or randomly distributed point scatterers and single or multiple extended obstacle scatterers are presented.

Our formulation is given as a coupled system, which combines the original Foldy Lax formulation for the point scatterers and the regular boundary integral equation for the extended obstacle scatterers.

Computationally, an efficient physically motivated Gauss Seidel iterative method is proposed to solve the coupled system, where only a linear system of algebraic equations for point scatterers or a boundary integral equation for a single extended obstacle scatterer is required to solve at each step of iteration.

Such macro-reentry can then be eliminated by extending the obstacle or by external stimuli that penetrate the excitable gap.

With these reports scrubbed, animal advocates will face extended delays and obstacles that may bring help too late – or not at all – for many suffering animals.

Alternatively, minicircle DNA vectors lacking bacterial DNA have been expressed at high levels in vivo for extended periods, yet obstacles in their mass production have limited their use.

In the quasi-steady propagation regime with the lowest blockage obstacles, burning pockets of gas extended only a few obstacles back from the flame-tip, whereas burning pockets were observed further back in tests with the higher obstacle blockage.

The pressure variations encountered by the different obstacles could be explained quantitatively with a granular force model, that assumes the formation of a mobilized volume of snow granules extending from the obstacle upstream whose dimensions depend on the incoming flow depth and the obstacle width.

In this paper, the method is first extended to include polygonal obstacles of any kind, allowing for less conservative workspace representations.

A building-block method, which gives the transmission and reflection matrices for a complex system from those of the parts, is applied to bifurcations, sudden area changes with or without extended inlets, and spherical obstacles (which may be lossy).

Visiting all the world's countries wasn't easy: war, revolution and the break-up of the Soviet Union were all sizeable obstacles that extended his mission.
