ABSTRACT
After some experience with a mechanical differential analyser of the Bush type, the author became convinced that there was a need for a smaller, cheaper instrument of this type with a faster and more convenient setup procedure. The large instruments are so large and expensive mainly because of the torque amplifiers they contain and are somewhat inconvenient to use because, aside from considerations of accessibility to the individual researcher, they have rather long and complicated setup procedures.

Efficient Nordsieck second derivative general linear methods: construction and implementation
In this paper, by considering the order conditions for second derivative general linear methods of order p and stage order $$q=p-1$$q=p-1, we investigate construction and implementation of these methods in the Nordsieck form with $$r=s+1=p$$r=s+1=p, ...
Implementation of Nordsieck second derivative methods for stiff ODEs
It is the purpose of this paper to study the construction and implementation of Nordsieck second derivative methods for the numerical integration of stiff systems of first order ordinary differential equations. We construct L-stable methods of order p = ...
General Nyström methods in Nordsieck form
The paper is concerned with the analysis of the error associated to a family of multi-value numerical methods for the solution of initial value problems based on special second order ordinary differential equations. Such methods, denoted as General ...
