Pressure-dependent Epanet Extension

In water distribution systems (WDSs), the available flow at a demand node is dependent on the pressure at that node. When a network is lacking in pressure, not all consumer demands will be met in full. In this context, the assumption that all demands are fully satisfied regardless of the pressure in the system becomes unreasonable and represents the main limitation of the conventional demand dr...

Alternative methods for learning in CSP Solvers

This paper outlines the major features of three solvers entered in this years CPAI solver competition. The solvers shared the same underlying architecture which is described in detail in the following paper, the base solver is rjw (submitted by Richard Wallace) which Diarmuid-rndi and Diarmuid-wtdi (both submitted by Diarmuid Grimes) are built on. Furthermore the solvers all used constraint wei...

Data collection outcomes comparing paper forms with PDA forms in an office-based patient survey.

PURPOSE We compared the completeness of data collection using paper forms and using electronic forms loaded on handheld computers in an office-based patient interview survey conducted within the American Academy of Family Physicians National Research Network. METHODS We asked 19 medical assistants and nurses in family practices to administer a survey about pneumococcal immunizations to 60 old...

Comparing Solvers for Large Systems of Nonlinear Algebraic Equations

The solution of systems of nonlinear algebraic equations is a problem which complexity grows as the number of equations increases. The number of engineering problems, which led to these systems, is increasing each year. In this paper we compare the performance of four advanced solvers for systems of nonlinear algebraic equations which have been collected from Internet repositories. We are parti...
