The paper presents some models for optimizing the production rate of an automatic multitest blood analyser. A blood analysis may require one or more tests. The performance of the analyser depends on the test compositions of the analyses and the design of the analyser itself, The design can be changed. The optimal design can be determined by solving a set partitioning problem, given a representa...

An automated analyser for total hydrocarbon contents and hydrocarbon composition (from methane to pentanes) was constructed and tested in both laboratory and field exploitation. It used two-channel analysis: continuous measurements of total hydrocarbon contents and periodic (90 or 150 s) composition analysis after separation of hydrocarbons on a gas chromatographic column. Flame ionization dete...

Introduction The C Parallel Analyser (Kone Oy, Instrument Division, Espoo, Finland) is a compact, new clinical analyser for photometric equilibrium and kinetic analyses. The instrument consists of a 24-channel parallel photometer, a control console with numeric display, an alphanumeric printer and a microcomputer which controls the analyser and takes care of automatic blanking and calibration. ...

BACKGROUND A study was undertaken to evaluate the reliability of a digital tracheal sound analyser (ELENS-DSA) in predicting nocturnal changes in airways resistance in asthmatic patients. This device allows continuous measurement of the proportion of the time occupied by wheezing (Wh%). METHODS Nocturnal polygraphic studies with simultaneous continuous monitoring of tracheal sounds and airway...
