It is also known that the mobile type of ILMs can be excited both in a spatially infinite system [6] and a

semi-infinite system driven at one end sinusoidally at a frequency in a linear stopping band above the passing band [7-11].

Then by selecting a finite number of them, the problem can be transformed into a

semi-infinite linear programming.

Figure 1 shows the two-dimensional Lamb mode, propagating towards the edge of a

semi-infinite plate along the x direction.

Kim and Fedorov [8] considered the case of mixed convection flow of a micropolar fluid past a

semi-infinite moving vertical porous plate with varying suction velocity normal to the plate in the presence of radiation.

In those models, the ground is regarded as a homogeneous

semi-infinite medium; the ground surface is treated as an isothermal surface by introducing a fictitious finite line source.

The theory allows for the expression of the reflector operator of a

semi-infinite periodic screen sequence, which then allows for the phenomenological characterization of the electromagnetic properties of an infinite periodic screen sequence, as well as its

semi-infinite or finite-layered parts.

The flow of incompressible viscous liquid is studied between two

semi-infinite parallel plates with partially filled space with porous medium.

The finite line source (FLS) model of the BHE in a

semi-infinite medium (Carslaw and Jaeger 1959) does account for vertical heat transfer with both the soil surface and deep earth.

The outdoor exposure geometry is modeled with a point receptor in air at a height h above a

semi-infinite volume of soil (earth floor) containing uniformly distributed gamma emitters.

For this purpose we formulate mathematical model describing heating or cooling of a

semi-infinite region.

Muthucumaraswamy and Ganesan [6] studied the effects of first order homogeneous chemical reaction on the flow past an impulsively started

semi-infinite vertical plate with uniform heat flux and mass diffusion.

Among steps in the process are the static hedging of barrier options, reformulation as a

semi-infinite problem, and avoiding model errors.
