It is also possible to combine some of the above solutions.

Another formulation of the above solution can be found if the following Maclaurin series:

The above solution can be very useful to design reinforcement, however, it has some practical limitations.

The above solutions minimize the variance of the output estimation error.

Thus, the above analytical solution provides a useful, but very qualitative, picture of the field behavior at the beam boundary.

The above solution assumed that the first house is the leftmost house.

The above solution is for the specific case of a box situated between and .

But this is tedious; the above solution is much faster.

With this, they have obtained a generalization of the above solution in the case when.

Halilsoy (1987) has considered an application of the transformation to the above solution.
