In Heemskerk the world's largest dual membrane municipal water treatment works ( WTW) “Jan-Lagrand” (55 Ml/d or 2,250 m3/h or approximately 15 MGD) was commissioned at the end of 1999. At Heemskerk WTW, pretreated surface water is subsequently treated by ultrafiltration (UF) and reverse osmosis (RO). The RO permeate is directly blended into drinking water without chemical disinfection. Before Heemskerk the dual membrane concept had not been considered on this scale, and during project preparation numerous developments and innovations needed to be flexibly accommodated into the ongoing design. Conceptual system development, pilot research and design and engineering were successfully conducted “in parallel”. This paper deals with the innovations that were materialized in Heemskerk, e.g. UF-membrane pretreatment, on line membrane integrity testing (UF and RO) for disinfection approval, and a dual floor building concept for membrane installations. This paper explains how these innovations could be accommodated into an ongoing design, while innovative testing was still proceeding.

From a survey of 77 people involved in information system development, it is estimated that on average more than 30 percent of operational software is devoted to the user-system interface (USI). Improvements are needed in early requirements definition, guidance and documentation of USI design.

Fast measurement of soil properties is of great value for farmland fertilizer management with the purpose of reducing environmental pollution caused by over-fertilizing and improving yield/cost ratio of land. In the study, an optical fiber sensing system was introduced. It consisted of a topsoil opener, a portable spectrophotometer (350-2500nm) and an optical fiber. Prediction models of total nitrogen (N), phosphorous (P), moisture content (MC), pH and organic matter (OM) were created in laboratory and validated by field testing. Soil samples were collected from 30 farmland blocks covering north of Zhejiang Province and south of Jiangsu Province, P.R. China. Partial least squares (PLS) regression with full cross-validation was used for calibration models building. The correlation coefficient of R2 between on-line and laboratory measurements of N, P, MC, pH and OM are 0.92, 0.78, 0.85, 0.83 and 0.76, respectively. The study shows the potential of using the optical fiber soil sensing system for next generation of precision farming.

Analyzed and recomposed to J2EE architecture, and during research of design pattern, the document bases on existing frame for achieving more application-layer reuse to engineer framework, and forms an optimal design pattern of electronic commerce. The pattern is actualized in on-line shopping system found on J2EE. The experiment results show that it reduces system development cycle, optimizes system structure, enhances the system's performance, and decreases the risk and the cost in software development when the framework and design pattern are combined artfully to use on electronic commerce

Help System

The sheer volume of information, 15 books and over 1,500 graphics, contained in CSC's corporate system development methodology, Catalyst,sm has created a need to have this information on-line. On-line access, it was felt, would dramatically impact productivity. To help support users and facilitate the use of Catalyst, the Microsoft (MS) help system, in conjunction with RoboHELPTM, was used to put Catalyst online in a hypertext format. Incorporating feedback and usability concerns was key in determining how its more than 20,000 users could best utilize this product. The design evolved over several months and in its final form also extended the limited functionality of the MS help system, providing a more robust product. This paper discusses the challenges surrounding the design of a large windows help system, approximately 53 MB in size (33 MB when fully compressed). The lessons learned can form the basis for creating an effective help system development process for meeting users' needs.

Conform™ extrusion is a very versatile manufacturing process enabling the production of a wide range of extruded profiles. It is critical to maintain a precise predefined wheel-tooling gap for the efficient running of the Conform extrusion process and to maintain high product quality. However, this is a challenging task due to the hostile environment, high operating temperatures, and required accuracy. An accurate high-temperature gap measurement system for Conform extrusion machinery, using a capacitive sensing system, is developed in this study. The sensor is implemented in a copper Conform extrusion machine, and experimental results are presented, providing for the first time a detailed view of Conform Extrusion gap behavior during production. It is shown that the proposed gap-sensing and control system results in a number of advantages, including reduced machine setup times, reduced flash (waste) rates, and on-line monitoring and control of gap size. The research is carried out in collaboration with Holton Machinery Ltd., a leading manufacturer of Conform Extrusion machinery.
