A new algorithm for the numerical evaluation of gradients in semiempirical methods is described. The method is approximately twice as fast as the schemes currently employed and produces gradients of comparable accuracy. This method has been tested by comparing the results obtained by the new method

β¦ Synopsis
it is now possible to produce pilot quantities of cast shapes of both pure and alloyed titanium. Castings of complex shape weighing up to several pounds have been made. Carbon, oxygen, and nitrogen content are reasonably comparable with commercial wrought titanium. The surface attainable is equal to that of good sandcast metals.

New techniques allow for more efficient boundary integral algorithms to compute the Dirichlet-Neumann map for Laplace's equation in two-dimensional exterior domains. Novelties include a new post-processor which reduces the need for discretization points with 50%, a new integral equation which reduce
