This paper reviews experience extending over 18 months obtained with the Elliott Automatic Laboratory Analysis (A.L.A.) system, coupled with a Teletype link for communicating with a computer situated half-a-mile away. The system has been used for the off-line processing by an Elliott 803 computer of data collected from AutoAnalyzers carrying out urea and electrolyte determinations. The A.L.A. equipment itself has proved reliable, apart from faults in the translator-timers occurring mostly during the first 3 months of routine operation, but the Teletype link has been subject to frequent breakdowns. The advantages of using the A.L.A. system of data-collection and computation have been confirmed, but disadvantages of this off-line system are discussed and reasons given why an on-line system of data-collection from AutoAnalyzers is preferred. The importance of reliable performance of laboratory data-acquisition and data-processing equipment in routine operation, and the need for good servicing arrangements, are stressed. The system described in this paper has been deficient in back-up servicing arrangements in respect of the A.L.A. equipment itself and of the Elliott 803 computer, but most of all in respect of the Teletype units. Alphabetical coding patterns have proved of little value as a means of reducing the number of reports requiring detailed scrutiny, but they have served to draw attention to markedly abnormal results.

Oswald Werner was one of the first to actually take data processing equipment into the field. This section is included as an illustration of the difficulties that face the technological innovator. The story illustrates the saying "Anything you can buy is already obsolete." Nonetheless, Werner has successfully implemented a sophisticated data collection, management, and analysis technique using readily available equipment and working under field conditions.

Aeration Control

On-line analyzers to monitor the effluent levels of ammonia and phosphate have been installed at all four nutrient removal activated sludge plants in Johannesburg. The data from these instruments is transferred to a SCADA system for control purposes. The on-line system is supplemented by laboratory data, which is stored on a separate computer system. A combination of this data is used for routine operational control. Dissolved oxygen probes are installed in the aerobic reactors of all plants and are used for aeration control. Automatic aeration control has recently been installed at one of the plants. In this paper some experience with on-line monitoring is discussed in terms of its usefulness and cost savings achieved. Savings of 1 million US $ in the purchase of phosphate precipitation chemicals have been achieved in the current financial year as a result of more efficient operational control.

Summary:—Competition is too keen to permit Management to continue with methods satisfactory five or ten years ago and some typical modern tools of management are reviewed.The use of Electronic Data processing equipment (EDP) can be overdone but when used wisely it can be of tremendous help in enabling management to fulfil its responsibilities and to make good decisions. Many areas are reviewed where EDP has been used to advantage, including processes used for planning, marketing, maintenance, inventory, finance, personnel and on-line systems such as automatic reservations, teletype switching, etc. Although the examples represent modern airline management techniques they are also usable by many other industries.

At the design stage, the work reported here recommends provision of the possibility of employing modern on-line spectral condition-monitoring equipment in order to improve the operational availability of nuclear power plant equipment, the reactor coolant pump (RCP). Following an analysis of the leading causes in the RCP forced outages, incorporation of the use of advanced on-line spectral condition-monitoring sensors and their corresponding data-processing equipment in new power plant designs is sought. They are employed in order to detect the incipient symptoms generated during the progression of potential system faults of major concern. Firstly, the applicability of recent developments in new sensors and data-processing techniques is examined. This examination concerns system status parameter monitoring in the analysis of vibration, motor current, partial discharge and wear debris. Finally, use of modern sensors and data-processing equipment, which are valuable for the intended condition-monitoring systems, is recommended. Furthermore, valuable information on the future trend of currently developing sensors at the research stage is briefly presented. This state-of-the-art review lays a foundation for developing modern comprehensive sensor networks to support efficient condition monitoring in other power plant rotating machines.

Summary The organisational efficiency of sample admission to the routine laboratory and the allocation to test methods has been improved by a scheduling system based on an on-line minicomputer. A flexible system has been constructed using multiple visual displays, which produce work allocation lists. Computer techniques have been developed which enable maximal use of the on-line system while retaining the general flexibility of high-level language coding, as implemented on an unsophisticated 12-bit processor. The file structure has been designed to provide cumulative information on the requesting patterns appropriate to any of the many sources of samples to thelaboratory, and to allow the automatic merging of worksheet and laboratory data, the latter being generated and transmitted from a second mini-computer system.

An on-line computer has been in use at Jodrell Bank since 1964, both controlling the Mk II radio telescope and performing data processing functions in connection with it. However this system is now being superseded, and the following describes the present state of development, including some facilities that are only now being constructed.An Argus 400 computer is associated with each of the two main telescopes. Each has 12 000 words of core store, the word length being 24-bits, and the time for obeying most functions is 12 μs. The 24-bit word length is well suited to the application since more than 16-bit accuracy is required in the coordinate transformation. This fact, and the very versatile organization of the Argus computer, makes the effective speed relatively higher when compared with faster machines of smaller word size. In addition a drum store of about 50,000 words capacity will be fitted to each machine, and CRT and graphical output devices are available. Each machine operates a permanent program, which performs a number of functions, including in the case of the Mk II telescope the control of the instrument itself. In addition, up to three “user” programs may be operated simultaneously; these may be on-line data collection, with links to the telescope control sections, or completely off-line background jobs. A wide selection of library routine, available to all programs, is permanently in the core store, and this makes the writing of programs a relatively simple matter.

SummaryThis paper reports on a computerised approach to the management of an epidemiological field trial, which aimed at determining the effects of insecticide-impregnated bed nets on the incidence of malaria in children. The development of a data system satisfying the requirements of the project and its implementation using a database management system are discussed. The advantages of this method of management in terms of rapid processing of and access to data from the study are described, together with the completion rates and error rates observed in data collection.
