The authors, with the help of a community hospital engineering staff, constructed a modern neurotological testing facility capable of performing on-line computer measurements of vestibulo-oculomotor, visual vestibulo-oculomotor, smooth pursuit, saccade, and optokinetic reflexes. The laboratory was built from component parts and uses a Digital Corporation laboratory computer. Programs from the UCLA Human Vestibular Laboratory were modified to work with the new laboratory. Construction and program modification cost $60,000 and was completed in seven months. The laboratory was working at full capacity six months after construction testing patients with suspected neurotologic and neurologic disorders. The procedures of construction as well as the financial and safety problems are discussed.

Scanning Electron

The use of large, remote computers in electron microscopy for picture processing is now quite common. In scanning electron microscopy the picture information is generated by electronically scanning the electron beam across the specimen and monitoring an electrical signal, and consequently the scanning electron microscope (SEM) lends itself quite easily to complete electronic control and signal processing by an on-line computer. A prototype on-line computer-SEM system was constructed at Berkeley using an IBM 1800 computer and a control console located at the SEM. The results obtained with this system clearly demonstrated the usefulness of this approach. In this paper we describe the use of a small laboratory computer to control the electron beam, to process the many different signals generated by the SEM, and to display the resulting information in the desired format. Although the system is capable of storing pictures and performing simple picture processing, its main advantage is that it allows one to perform unique experiments with the SEM, to correct and analyze the data during the experiment, and to store the information for future processing and display. An additional advantage of the system is that complex SEM experiments can be performed without the usual delay time and additional cost required for constructing new electronics for each experiment; it is this system flexibility that we wish to illustrate by the results presented below.

Data Summaries

Data from Automatic water quality monitors and gauging stations on the Bedford Ouse are telemetered to the Cambridge office of the Creat Ouse River Division of the Anglian Water Authority. A mini-computer has been installed to log data from the out-stations, convert data to meaningful units, prepare data summaries, check for alarm conditions and forecast flow and quality up to 80 hours ahead at key locations along the river system. The system provides information on flow and quality conditions in real time and has been used to forecast the movement of pollutants along the river system. A generalised suite of computer programs have been developed for data management and forecasting and a micro-processor controlled water quality monitor is currently under development.

The Individual

Innovative low transformation temperature (LTT) welding filler materials are featuring a characteristic chemical composition which favors the formation of martensite at comparatively low temperatures. This permits deliberate adjustment of welding residual stresses. Even though numerous investigations can be found in the literature on this issue, they provide only little insight into the interaction between phase transformation and resulting welding residual stresses. For this purpose, a component weld test was performed in a special large-scale testing facility. The results illustrate that the desired residual stress control by using LTT alloys is actually feasible. With increasing shrinkage restraint, however, higher tensile residual stresses are formed in transverse direction of the weld. By contrast, the residual stress level in longitudinal weld direction is nearly independent of the restraint conditions. On-line stress analysis revealed that the amount of stress reduction during cooling of the individual weld runs is dependent on the weld volume undergoing phase transformation. Overall, evidence was furnished that the approach of residual stress engineering by LTT alloys is suitable even in the case of large-scale multilayer welding.

The use of a laboratory computer system to deal with specimen problems is described. Problems such as ‘insufficient material’ or ‘haemolysis’ are entered by reception staff or by bench workers so that resolution of the problem will not be overlooked; problems are then listed and dealt with by the duty biochemist. Specimens on printed worksheets are annotated ‘urgent’ where appropriate. Results obtained on-line, which are above top standard, automatically cause the specimen to reappear on the next worksheet marked ‘dilution required’. Data relating to its use over a three-month period are presented together with some comments on the causation of specimen problems and their prevention.

Database Program

AbstractTwo new VAX/VMS computer programs are presented for accessing and searching the Powder Diffraction File (PDF) (1989) of the JCPDS-International Centre for Diffraction Data (ICDD). The programs use binary mapped index files which affords rapid searches of the database. Program LOGIC permits entries in the database to be selected by chemistry, peak position or name constraints. The selected entries may be displayed, printed or graphed. The program can display or print entries from the full PDF-2 (1989) database, if on-line. Program SEARCH searches for patterns in the database which match an unknown set of peaks; the program may be optimized for a wide variety of applications including identification of component phases in mixtures. Commands may be entered to the programs in two modes. In the “novice-friendly” mode, users must answer questions to select options. However, experienced users may opt to use a concise one-line command syntax. The modes may be mixed.
