This note studies the relationship between Hutton's quasi-uniformities and Shi's quasi-uniformities. It is shown that when $L$ satisfies``multiple choice principle" for co-prime elements, the category of Hutton's quasi-uniform spaces is a bireflective full subcategory of the category of Shi's quasi-uniform spaces. Especially, if the remote-neighborhood mapping defined by Shi preserves arbitrary...

Transformations from the Enterprise Distributed Object Computing (EDOC) to Enterprise JavaBeans (EJB) are examined herein from the point of view of an efficiency characteristic of result models. Transformations are composed of mapping operations. Mapping operations map an element or a group of elements of the EDOC model into an element or a group of elements of the EJB model. A standard proposa...
