A finite difference equation is developed for the stream function in cylindrical coordinates with axial symmetry which is applicable to an irregular mesh having different length and radial dimensions. In addition, the length and radial dimensions...

"In the magnetic testing of satellites and spacecraft, very homogeneous fields are needed. One method of obtaining such fields is to use a number of circular coils on a common axis. The parameters of the best three-and four-coil systems were...

"A method using steady-state transforms is described which indicates how the sum function of a Fourier series may be obtained. The method can be applied to problems arising from circuits containing concentrated circuit parameters, but is not quite...

"A method is described for obtaining the trees of a v vertex complete graph through an iterative process. The iterative process is as follows, first find all the trees of a 3 vertex complete graph, then by an appropriate substitution the trees of a...

"A series of stiffened shells made of plastic were tested to verify the theoretical equations for the effect of edge conditions on the buckling of stiffened and framed shells. The theory was developed by calculating the deflections during loading...

"In order to operate a power system at optimum economy, the production costs and transmission losses must be coordinated. A straightforward derivation of the co-ordination conditions is given. A widely adopted method of finding transmission penalty...
