Extended Static Checking by Calculation Using the Pointfree Transform [PDF]

open access: yes, 2009
The pointfree transform offers to the predicate calculus what the Laplace transform offers to the differential/integral calculus: the possibility of changing the underlying mathematical space so as to enable agile algebraic calculation. This paper addresses the foundations of the transform and its application to a calculational approach to extended ...

Advanced Methods for Static and Dynamic Shafting Calculations

open access: yesBrodogradnja : An International Journal of Naval Architecture and Ocean Engineering for Research and Development, 2006
This article introduces a computer program developed by Wärtsilä Switzerland which provides a three-dimensional model of the shafting for the calculation of coupled vibrations, alignment and whirling in a ship propulsion plant. Based on the fi nite-element method the program covers both dynamic and static problems. Each node has six degrees of freedom.
