Abstract In radial partition immunoassay, radial chromatography is used for performing an immunoassay. We describe the application of this technology to the measurement of digoxin in serum by enzyme immunoassay, with the entire testing procedure carried out on glass-fiber filter paper. A sample is applied to a small central area of the filter paper, where it reacts with the antibody to digoxin immobilized there. Subsequently, enzyme-labeled digoxin is applied to react with remaining antibody sites. After incubation, substrate for the enzyme is applied to the center of the reaction area and washes out any unbound label to the periphery of the paper. This step also initiates the enzyme reaction, which is quantified by front-surface fluorescence. A microprocessor-controlled automated instrument has been developed to process the filter paper matrix through the above sequence, and calculate the final result. Total testing time for digoxin is less than 7 min.

This study examined the feasibility of repeated self-administration of a newly developed battery of mental acuity tests which may have application in screening for fitness-for-duty or for persons who may be exposed to environmental stress, toxic agents, or disease. 16 subjects self-administered 18 microcomputer-based tests (13 new, 5 “core”), without proctors, over 10 sessions. The hardware performed well throughout the study and the tests appeared to be easily self-administered. Stabilities and reliabilities of the tests from the “core” battery were comparable to those obtained previously under more controlled experimental conditions. Eight of the new tests exceeded minimum criteria for metric and practical requirements and can be recommended as additions to the menu. Although the average retest reliability was high, cross-correlations between tests were low, implying factorial diversity. The menu can be used to form batteries with flexible total testing time which are likely to tap different mental processes and functions.

A motion picture test of perceptual abilities has been developed for use with elementary school children. The test has two parts. In Part 1 the child must identify a hidden stimulus figure within one of four designs. In Part 2 the child must identify from four alternatives a figure formed by separate lines which have been presented successively. The test is a self-administering 16-mm sound film and requires about 30 min. of total testing time.

Aging Factor

In this study, ageing effect for xenon through experiment has been studied. The study focuses on the modeling, ageing characteristics of xenon car headlight. The modeling of the lamp is based on spline interpolation algorithms. In this model, the voltage drop at the electrodes is considered as the aging factor. Ageing characteristics under the flicker condition for 4 types of xenon car headlight lamps have been measured. The flicker time is 4 seconds turn on and 2 seconds turn off, and the total testing time is 48 hours. The luminous, voltage and current of the lamp are measured. It is found that even a short period of flicker significantly affects the life time of the lamp.

Generation of test plans is a crucial step for testing VLSI circuits. This paper presents a modified approach to test plan generation for the BILBO test methodology. A few limitations of the existing approaches have been identified and methods to address these have been suggested. The proposed approach has been implemented for the general case of n-port combinational logic blocks (CLBs). However, due to limitations of space and for clarity, only 2-port CLBs are considered in this paper. For this case, the problem is modelled as a Step Scheduling Matrix and an algorithm is presented for the solution. The algorithm has been tested on a number of benchmark circuits and the results are compared with those obtained through existing methods. The effectiveness of the proposed approach is clear from the results, as it contributes to the reduction in total testing time as well as generates a larger number of test plans.
