Students have difficulty learning data flow diagram material because of the lack references and constraints in accessing other reference sources. In addition, students also understanding notations symbols used making DFDs. Therefore interactive multimedia aims to produce computer-based products, which can be by as a source media diagrams at Instituto Superior Cristal. The resulting product is f...

We study the stationary Poiseuille flow in a cylindrical channel of arbitrary cross-section with temperature dependent viscosity and internal dissipation. We assume the flow-rate Φ given and the axial pressure gradient μ unknown. This leads to a nonlocal problem. We show the existence in the response diagram, the plane (Φ, μ), of two turning points. 1. In this paper we study the stationary Pois...

Modern scientific research is characterized by extensive computerized data processing of laboratory results and other scientific data. Such processes are often complex, consisting of several data manipulating steps. We refer to such processes as dataflows, to distinguish them from more general workflows. General workflows also emphasize the control flow aspect of a process, whereas our focus is...

Hypotheses and some results of the three-phase traffic theory by the author are compared with results of the fundamental diagram approach to traffic flow theory. A critical discussion of model results about congested pattern features which have been derived within the fundamental diagram approach to traffic flow theory and modelling is made. The empirical basis of the three-phase traffic theory...

This document describes use cases and documents call flows that require the History-Info header field to capture the Request-URIs as a Session Initiation Protocol (SIP) Request is retargeted. The use cases are described along with the corresponding call flow diagrams and messaging details.

We show that the minimum energy requirement for separation of a multicomponent mixture in a three-product Petlyuk arrangement is equal to the minimum energy for the most difficult of the two separations (top/middle or middle/bottom product) in a conventional single column. In the Vmin diagram (part 1 of this series), this is simply the highest peak. These results are based on an analytical solu...

: In this article, the ‘information channel diagram’ (ICD) approach is introduced as a diagrammatical tool for modelling information flow during the delivery phase of organisations in which goods are deployed or delivered to customers. An initial review and evaluation of current tools for modelling information flow will be conducted based on the characteristics of information flow during the de...
