A few remarks concerning the flow of fluid under a sluice gate

"August, 1965.""The two-dimensional, irrotatational flow of incompressible fluid under a sluice gate in a gravitational field has been treated by de Boor (Ref. 1) using the integral equation method of Birkhoff and Zarantonello (Ref. 2). However, de Boor was not able to satisfactorily satisfy the constant pressure condition on the free streamline in the neighborhood of the point at infinity. He established (using certain hypotheses) that this difficulty occurred because the singularity in the velocity potential at this point did not have a continuous derivative. The author has determined the apparent form of this singularity. By removing part of it, he has obtained solutions which appear to be substantially more accurate than those obtained by deBoor."--Abstract

Developing engineering design core competences through analysis of industrial products

Many product development projects are directed towards designing an upgraded variant of an existing product. These redesign projects require that the engineering designers understand needs and requirements from users, and know how the existing product functions and how it is manufactured. For an engineering designer to be able to contribute to a redesign project, he/she must have core competences to carry through a composite product analysis, which encompasses both a user-oriented and a technical side. We have developed and refined a product analysis method and a staging of it, which is very productive in building the students' competences
